The purpose of this study was to assess the effectiveness of a menopause clinic to enhance trainees' medical knowledge. Between July 2004 and May 2007, 73 resident physicians completed a rotation that included a weekly menopause clinic and completion of a pretest and posttest examination. Each test contained questions on topics covering menopause, perimenopause, and general women's health. At the end of each testing session, a total score and a menopause score were given. The mean (SD) pretest menopause score and total score were 63.2% (13.3%) and 63.7% (11.3%), respectively. The mean posttest increase in the menopause score was 14%, with a median score increase of 10.2% (P < 0.0001). The posttest results ranged from a maximum decrease of 7.8% to a maximum increase of 47.1%. The mean increase in the total score was 13%, with a median increase of 10.7% (P < 0.0001). For the posttest total score, the range went from -7.2% to 39.3%. There was no correlation between the score changes and the number of clinic sessions attended, the resident specialties (obstetrics/gynecology vs non-obstetrics/gynecology), the level of training (postgraduate year 1 or 2), or the examination order (test A vs test B taken first). Menopause clinics can add to resident physician knowledge about menopause-related matters. Menopause clinics may help educate future physicians in their ability to care for postmenopausal women.

A Note on Stochastic Ordering of the Latent Trait Using the Sum of Polytomous Item Scores

In contrast to dichotomous item response theory (IRT) models, most well-known polytomous IRT models do not imply stochastic ordering of the latent trait by the total test score (SOL). This has been thought to make the ordering of respondents on the latent trait using the total test score questionable and throws doubt on the justifiability of using…

The COPD assessment test (CAT) consists of eight nonspecific scores of quality of life. The aim of this study was to compare the health-related quality of life and severity of airflow limitation in patients with asthma, COPD, and asthma-COPD overlap syndrome (ACOS) using the CAT. We examined CAT and lung functions in 138 patients with asthma, 99 patients with COPD, 51 patients with ACOS, and 44 patients with chronic cough as a control. The CAT score was recorded in all subjects, and the asthma control test was also administered to patients with asthma and ACOS. The CAT scores were compared, and the relationships between the scores and lung function parameters were analyzed. The total CAT scores and scores for cough, phlegm, and dyspnea were higher in patients with ACOS than in patients with asthma and COPD. The total CAT scores were correlated with the percent predicted forced expiratory volume in 1 second only in patients with COPD. The total CAT scores and dyspnea scores adjusted by the percent predicted forced expiratory volume in 1 second were higher in patients with ACOS than in patients with COPD and asthma. The CAT scores and asthma control test scores were more closely correlated in patients with ACOS than in patients with asthma. Patients with ACOS have higher disease impacts and dyspnea sensation unproportional to the severity of airflow limitation.

Neurocognitive test scores are often considered an important aspect of concussion management. To best use these data, clinicians must understand potential factors that may influence baseline performance on these tests. To determine preexisting factors that may influence performance on the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT). Cross-sectional study. Research laboratory. A total of 486 National Collegiate Athletic Association Division I collegiate student-athletes. To determine neurocognitive functioning and total symptom score at baseline, ImPACT was administered. Outcomes were verbal memory, visual memory, visual motor speed, reaction time, and total symptom score. A self-report demographic section at the beginning of ImPACT was used to gather information concerning previous treatment for headaches, migraines, and psychiatric conditions; diagnosis of attention-deficit/hyperactivity disorder; and exposure to previous strenuous exercise. We conducted multivariate analyses of variance to determine if the ImPACT composite and total symptom scores differed according to preexisting factors (P < .0083). Sex showed an effect on verbal memory (P = .001), visual motor speed (P < .001), and reaction time (P = .006), with women performing better than men. A previous diagnosis of attention-deficit/hyperactivity disorder affected visual motor speed (P = .008). Previous treatment for headaches (P < .001), migraines (P = .001), a psychiatric condition (P < .001), or a diagnosis of attention-deficit/hyperactivity disorder (P < .001) all showed effects on the total symptom score. Strenuous exercise did not affect neurocogntive performance or total symptom score. Based on our findings and the previous literature, we suggest that many preexisting factors influence baseline neurocognitive data. Baseline testing is an important aspect of concussion management. Sports medicine professionals should be cognizant of these factors when developing concussion-management protocols.

The Stroop Color-Word Interference Test (Stroop) measures cognitive flexibility, selective attention, cognitive inhibition and information processing speed. The Tower of London-Drexel University version test (TOL) assesses higher-order problem solving and executive planning abilities. In this study, as part of the Spanish normative studies project in young adults (NEURONORMA young adults), we present normative data for the Stroop and young adults TOL tests. The sample consisted of 179 participants who are cognitively normal and range in age from 18 to 49 years. Tables are provided to convert raw scores to scaled scores. Scores adjusted for sociodemographic factors were obtained by applying linear regression techniques. No effects were found for age and sex in either test. Educational level impacted most of the Stroop test variables and some of the TOL scores (Total Moves score and Total Initiation Time score). The norms obtained will be extremely useful in the clinical evaluation of young Spanish adults. Copyright © 2011 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

2015-12-01

The Dimensional Obsessive-Compulsive Scale (DOCS) is a promising measure of obsessive-compulsive disorder (OCD) symptoms but has received minimal psychometric attention. We evaluated the utility and reliability of DOCS scores. The study included 832 students and 300 patients with OCD. Confirmatory factor analysis supported the originally proposed four-factor structure. DOCS total and subscale scores exhibited good to excellent internal consistency in both samples (α = .82 to α = .96). Patient DOCS total scores reduced substantially during treatment (t = 16.01, d = 1.02). DOCS total scores discriminated between students and patients (sensitivity = 0.76, 1 - specificity = 0.23). The measure did not exhibit gender-based differential item functioning as tested by Mantel-Haenszel chi-square tests. Expected response options for each item were plotted as a function of item response theory and demonstrated that DOCS scores incrementally discriminate OCD symptoms ranging from low to extremely high severity. Incremental differences in DOCS scores appear to represent unbiased and reliable differences in true OCD symptom severity. © The Author(s) 2014.

Validity of four approaches of using repeaters' MCAT scores in medical school admissions to predict USMLE Step 1 total scores.

2010-10-01

This study investigated the validity of four approaches (the average, most recent, highest-within-administration, and highest-across-administration approaches) of using repeaters' Medical College Admission Test (MCAT) scores to predict Step 1 scores. Using the differential predication method, this study investigated the magnitude of differences in the expected Step 1 total scores between MCAT nonrepeaters and three repeater groups (two-time, three-time, and four-time test takers) for the four scoring approaches. For the average score approach, matriculants with the same MCAT average are expected to achieve similar Step 1 total scores regardless of whether the individual attempted the MCAT exam one or multiple times. For the other three approaches, repeaters are expected to achieve lower Step 1 scores than nonrepeaters; for a given MCAT score, as the number of attempts increases, the expected Step 1 decreases. The effect was strongest for the highest-across-administration approach, followed by the highest-within-administration approach, and then the most recent approach. Using the average score is the best approach for considering repeaters' MCAT scores in medical school admission decisions.

The objective of this study was to evaluate the inter-rater reliability, test-retest reliability, concurrent validity, and discriminant validity of the Complex Task Performance Assessment (CTPA): an ecologically valid performance-based assessment of executive function. Community control participants (n = 20) and individuals with mild stroke (n = 14) participated in this study. All participants completed the CTPA and a battery of cognitive assessments at initial testing. The control participants completed the CTPA at two different times one week apart. The intra-class correlation coefficient (ICC) for inter-rater reliability for the total score on the CTPA was .991. The ICCs for all of the sub-scores of the CTPA were also high (.889-.977). The CTPA total score was significantly correlated to Condition 4 of the DKEFS Color-Word Interference Test (p = -.425), and the Wechsler Test of Adult Reading (p  = -.493). Finally, there were significant differences between control subjects and individuals with mild stroke on the total score of the CTPA (p = .007) and all sub-scores except interpretation failures and total items incorrect. These results are also consistent with other current executive function performance-based assessments and indicate that the CTPA is a reliable and valid performance-based measure of executive function.

The aim of this study was to investigate the prevalence of olfactory dysfunction and evaluate the relationship between olfactory function and nutritional status, comorbidity, and the results of a neurocognitive test in geriatric patients who do not suffer from neurodegenerative disease. A total of 45 patients who visited the Geriatric Health Center of Chungnam National University Hospital were enrolled in this study. Olfactory function was assessed using a Korean Version of Sniffin' Stick Test II. Cognitive status of all participants was assessed with the MMSE-K (Korean version of the Mini-Mental State Examination). Nutritional status was assessed with body mass index, Mini-Nutritional Assessment (MNA), and serum total protein and albumin. A total of 45 participants were enrolled in this study. Of these subjects, 28 were men and 17 were women, with a mean age of 71.7±5.16 years. Nine (20%) were normosmia, 13 (28.9%) were hyposmia, and 23 (51.1%) were anosmia. Thirty-six patients (80%) suffered from olfactory dysfunction (anosmia or hyposmia). MMSE score showed significant correlation with MNA score. There were significant negative correlations between age and total TDI (threshold, discrimination, and identification) score, discrimination score, identification score, and MMSE score. MMSE score showed significant correlation with discrimination score and identification score. However, MNA score did not show any significant correlation with olfactory function test results. Although olfactory function was not influenced by nutritional status, abilities of discrimination and identification of odors were associated with cognitive function in geriatric patients.

The purpose of this study was to predict baseline neurocognitive and postural control performance using a measure of motivation, high school grade point average (hsGPA), and Scholastic Aptitude Test (SAT) score. Cross-sectional. Clinical research center. Eighty-eight National Collegiate Athletic Association Division I incoming student-athletes (freshman and transfers). Participants completed baseline clinical concussion measures, including a neurocognitive test battery (CNS Vital Signs), a balance assessment [Sensory Organization Test (SOT)], and motivation testing (Rey Dot Counting). Participants granted permission to access hsGPA and SAT total score. Standard scores for each CNS Vital Signs domain and SOT composite score. Baseline motivation, hsGPA, and SAT explained a small percentage of the variance of complex attention (11%), processing speed (12%), and composite SOT score (20%). Motivation, hsGPA, and total SAT score do not explain a significant amount of the variance in neurocognitive and postural control measures but may still be valuable to consider when interpreting neurocognitive and postural control measures.

Universities in Thailand are preparing for Thailand's integration into the ASEAN Economic Community (AEC) by increasing the number of tests in English language. English language is not the native language of Thailand Differences in English language proficiency may affect scores among test-takers, even when subject knowledge among test-takers is comparable and may falsely represent the knowledge level of the test-taker. To study the impact of English language multiple choice test questions on test scores of medical students. The final examination of fourth-year medical students completing internal medicine rotation contains 120 multiple choice questions (MCQ). The languages used on the test are Thai and English at a ratio of 3:1. Individual scores of tests taken in both languages were collected and the effect of English language on MCQ was analyzed Individual MCQ scores were then compared with individual student English language proficiency and student grade point average (GPA). Two hundred ninety five fourth-year medical students were enrolled. The mean percentage of MCQ scores in Thai and English were significantly different (65.0 ± 8.4 and 56.5 ± 12.4, respectively, p < 0.001). The correlation between MCQ scores in Thai and English was fair (Spearman's correlation coefficient = 0.41, p < 0.001). Of 295 students, only 73 (24.7%) students scored higher when being tested in English than in Thai language. Students were classified into six grade categories (A, B+, B, C+, C, and D+), which cumulatively measured total internal medicine rotation performance score plus final examination score. MCQ scores from Thai language examination were more closely correlated with total course grades than were the scores from English language examination (Spearman's correlation coefficient = 0.73 (p < 0.001) and 0.53 (p < 0.001), respectively). The gap difference between MCQ scores in both languages was higher in borderline students than in the excellent student group (11.2 ± 11.2 and 7.1 ± 8.2, respectively, p < 0.001). Overall, average student English proficiency score was very high, at 3.71 ± 0.35 from a total of 4.00. Mean student GPA was 3.40 ± 0.33 from a possible 4.00. English language MCQ examination scores were more highly associated with GPA than with English language proficiency. The use of English language multiple choice question test may decrease scores of the fourth-year internal medicine post-rotation final examination, especially those of borderline students.

To determine whether significant correlations existed among quantitative and qualitative predictors of students' academic success and quantitative outcomes of such success over a 12-year period in a small university's premedical program. A database was assembled from information on the 199 graduates who earned BS degrees in biology from Barry University's School of Natural and Health Sciences from 1980 through 1991. The quantitative variables were year of BS degree, total score on the Scholastic Aptitude Test (SAT), various measures of undergraduate grade-point averages (GPAs), and total score on the Medical College Admission Test (MCAT); and the qualitative variables were minority (54% of the students) or majority status and transfer (about one-third of the students) or nontransfer status. The statistical methods were multiple analysis of variance and stepwise multiple regression. Statistically significant positive correlations were found among SAT total scores, final GPAs, biology GPAs versus nonbiology GPAs, and MCAT total scores. These correlations held for transfer versus nontransfer students and for minority versus majority students. Over the 12-year period there were significant fluctuations in mean MCAT scores. The students' SAT scores and GPAs proved to be statistically reliable predictors of MCAT scores, but the minority or majority status and the transfer or nontransfer status of the students were statistically insignificant.

Carotid artery atherosclerosis is a major risk factor for stroke and subsequent cognitive impairment. Prospective population studies have shown associations between carotid intima-media thickness (IMT) and stenosis and cognitive decline and dementia in elderly stroke-free persons, whereas results in the middle-aged are conflicting. In this prospective population-based study, 4,371 stroke-free middle-aged participants underwent carotid ultrasound examination and assessment of vascular risk factors at baseline and were tested for cognitive function 7 years later. Associations between IMT, number of plaques and total plaque area and cognitive test scores on verbal memory test, digit symbol-coding test and tapping test were assessed in linear regression models. In the multivariable analyses adjusted for sex, age, education, depression and vascular risk factors, the presence of plaques was significantly associated with lower test scores on the verbal memory test (p = 0.01) and on the digit symbol-coding test (p = 0.03). The number of plaques (p = 0.01) and the total plaque area (p = 0.02) were associated with lower scores on the verbal memory test. No significant association was seen between common carotid artery IMT and cognitive test scores. The tapping test was not associated with the carotid ultrasound variables. In this middle-aged general population, subclinical carotid atherosclerosis measured as the presence of plaques, number of plaques and total plaque area were independent long-term predictors of lower cognitive test scores.

Field test results are reported for the Observable Indicators of Nursing Home Care Quality Instrument-Assisted Living Version, an instrument designed to measure the quality of care in assisted living facilities after a brief 30-minute walk-through. The OIQ-AL was tested in 207 assisted-living facilities in two states using classical test theory, generalizability theory, and exploratory factor analysis. The 34-item scale has a coherent six-factor structure that conceptually describes the multidimensional concept of care quality in assisted living. The six factors can be logically clustered into process (Homelike and Caring, 21 items) and structure (Access and Choice; Lighting; Plants and Pets; Outdoor Spaces) subscales and for a total quality score. Classical test theory results indicate most subscales and the total quality score from the OIQ-AL have acceptable interrater, test-retest, and strong internal consistency reliabilities. Generalizability theory analyses reveal that dependability of scores from the instrument are strong, particularly by including a second observer who conducts a site visit and independently completes an instrument, or by a single observer conducting two site visits and completing instruments during each visit. Scoring guidelines based on the total sample of observations (N = 358) help guide those who want to use the measure to interpret both subscale and total scores. Content validity was supported by two expert panels of people experienced in the assisted-living field, and a content validity index calculated for the first version of the scale is high (3.43 on a four-point scale). The OIQ-AL gives reliable and valid scores for researchers, and may be useful for consumers, providers, and others interested in measuring quality of care in assisted-living facilities.

The aim of this pilot study was to evaluate reproducibility of the Jebsen Taylor Test of Hand Function (JTTHF) in children. Eighty-seven typically developing children 5 to 10 years old were included from five Outside School Hours Care centers in the Greater Brisbane Region, Australia. Hand function was assessed on two occasions with a modified JTTHF, then reproducibility was assessed using Intraclass Correlation Coefficient (ICC [3,1]) and the Standard Error of Measurement (SEM). Total scores for male and female children were not significantly different. Five-year-old children were significantly different to all other age groups and were excluded from further analysis. Results for 71 children, 6 to 10 years old were analyzed (mean age 8.31 years (SD 1.32); 33 males). Test-retest reliability for total scores on the dominant and nondominant hands were ICC 0.74 (95% CI 0.61, 0.83) and ICC 0.72 (95% CI 0.59, 0.82), respectively. 'Writing' and 'Simulated Feeding' subtests demonstrated poor reproducibility. The Smallest Real Difference was 5.09 seconds for total score on the dominant hand. Findings indicate good test-retest reliability for the JTTHF total score to measure hand function in typically developing children aged 6 to 10 years.

Service-learning provides an excellent pedagogy for introducing students to clients of different cultural backgrounds, helping students become aware of the issues these clients face related to culture and health care, and teaching culturally appropriate care. The Transcultural Self-Efficacy Tool was used to evaluate self-perceived cultural competence in a convenience sample of 60 baccalaureate nursing students enrolled in a community health nursing course following the completion of service-learning projects with local and international communities. Pre- and posttests were analyzed based on total scores and subscale (cognitive, practical, and affective) scores. A paired-samples t test compared the mean pretest total score to the mean posttest total score, which demonstrated a significant increase. In addition, paired-samples t tests demonstrated a significant increase in each subscale.

The purpose of this study was to adapt the English version of the Hospital for Special Surgery (HSS) knee score for use in a Turkish population and to evaluate its validity, reliability and cultural adaptation. Standard forward-back translation of the HSS knee score was performed and the Turkish version was applied in 73 patients. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Mini-Mental State Examination and sit-to-stand test were also performed and analyzed. Internal consistency reliability was tested using Cronbach's alpha. The intraclass correlation coefficient (ICC) was used to calculate the test-retest reliability at one-week intervals. Validity was assessed by calculating the Pearson correlation between the HSS, WOMAC and sit-to-stand test scores. The ICC ranged from 0.98 to 0.99 with high internal consistency (Cronbach's alpha: 0.87). The WOMAC score correlated with total HSS score (r: -0.80, p<0.001) and sit-to-stand score (r: 0.12, p: 0.312). The Turkish version of the HSS knee score is reliable and valid in evaluating the total knee arthroplasty in Turkish patients.

2001-11-01

This study examines the reliability of the Melbourne Assessment of Unilateral Upper Limb Function: a quantitative test of quality of movement in children with neurological impairment. The assessment was administered to 20 children aged from 5 to 16 years (mean age 9 years 10 months, SD 2 years 10 months) who had various types and degrees of cerebral palsy (CP). The performances of the 20 children during assessment were videotaped for subsequent scoring by 15 occupational therapists. Scores were analyzed for internal consistency of test items, inter- and intrarater reliability of scorings of the same videotapes, and test-retest reliability using repeat videotaping. Results revealed very high internal consistency of test items (alpha=0.96), moderate to high agreement both within and between raters for all test items (intraclass correlations of at least 0.7) apart from item 16 (hand to mouth and down), and high interrater reliability (0.95) and intrarater reliability (0.97) for total test scores. Test-retest results revealed moderate to high intrarater reliability for item totals (mean of 0.83 and 0.79) for each rater and high reliability for test totals (0.98 and 0.97). These findings indicate that the Melbourne Assessment of Unilateral Upper Limb Function is a reliable tool for measuring the quality of unilateral upper-limb movement in children with CP.

The Motivated Strategies for Learning Questionnaire (MSLQ) purports to measure motivation using the expectancy-value model. Although it is widely used in other fields, this instrument has received little study in health professions education. The purpose of this study was to evaluate the validity of MSLQ scores. We conducted a validity study evaluating the relationships of MSLQ scores to other variables and their internal structure (reliability and factor analysis). Participants included 210 internal medicine and family medicine residents participating in a web-based course on ambulatory medicine at an academic medical centre. Measurements included pre-course MSLQ scores, pre- and post-module motivation surveys, post-module knowledge test and post-module Instructional Materials Motivation Survey (IMMS) scores. Internal consistency was universally high for all MSLQ items together (Cronbach's α = 0.93) and for each domain (α ≥ 0.67). Total MSLQ scores showed statistically significant positive associations with post-test knowledge scores. For example, a 1-point rise in total MSLQ score was associated with a 4.4% increase in post-test scores (β = 4.4; p < 0.0001). Total MSLQ scores showed moderately strong, statistically significant associations with several other measures of effort, motivation and satisfaction. Scores on MSLQ domains demonstrated associations that generally aligned with our hypotheses. Self-efficacy and control of learning belief scores demonstrated the strongest domain-specific relationships with knowledge scores (β = 2.9 for both). Confirmatory factor analysis showed a borderline model fit. Follow-up exploratory factor analysis revealed the scores of five factors (self-efficacy, intrinsic interest, test anxiety, extrinsic goals, attribution) demonstrated psychometric and predictive properties similar to those of the original scales. Scores on the MSLQ are reliable and predict meaningful outcomes. However, the factor structure suggests a simplified model might better fit the empiric data. Future research might consider how assessing and responding to motivation could enhance learning. © Blackwell Publishing Ltd 2011.

The aim of this study was to analyze the validity and reliability of the Turkish version (ICOAP-TR) of the intermittent and constant osteoarthritis pain (ICOAP) questionnaire in patients with knee osteoarthritis (OA). Thirty-eight volunteer patients diagnosed with knee OA answered the questionnaire twice with an interval of 2-4 days. The reliability of the measurement was assessed using Cronbach's alpha coefficient and intraclass correlation (ICC) for test-retest reliability. Criterion validity was tested against the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain score and visual analog scale (VAS) designed to assess the perceived discomfort rated by the patient. Test-retest reliability was found to be ICC=0.942 for total score, 0.902 for constant pain subscale, and 0.945 for intermittent pain subscale. Internal consistency was tested using Cronbach's alpha and was found to be 0.970 for total score, 0.948 for constant pain subscale, and 0.972 for intermittent pain subscale. For criterion validity, the correlation between the total score of ICOAP-TR and WOMAC pain subscale was r=0.779 (p<0.05), and correlation between total score of ICOAP-TR and VAS was r=0.570 (p<0.05). The ICOAP-TR is a reliable and valid instrument to be used with patients with knee OA.

Objective Many studies have reported that olfactory dysfunction frequently occurs in chronic rhinosinusitis (CRS) populations; however, the prevalence and degree of olfactory loss has not been systematically studied. The aims of this study are to use combined data to report the prevalence of olfactory dysfunction and to calculate weighted averages of olfactory test scores in CRS patients. Data Sources A search was conducted in PubMed and Scopus, following the methods of Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Review Methods Studies reporting the prevalence of olfactory dysfunction using objective measures or olfactory test scores using validated scales were included. Results A total of 47 articles were included in systematic review and 35 in the pooled data analysis. The prevalence of olfactory dysfunction in chronic rhinosinusitis was found to be 30.0% using the Brief Smell Identification Test, 67.0% using the 40-item Smell Identification Test, and 78.2% using the total Sniffin’ Sticks score. Weighted averages ± standard deviation of olfactory test scores were 25.96±7.11 using the 40-item Smell Identification Test, 8.60±2.81 using the Brief Smell Identification Test, 21.96±8.88 using total Sniffin’ sticks score, 5.65±1.51 using Sniffin’ Sticks threshold, 9.21±4.63 using Sniffin’ Sticks discrimination, 9.47±3.92 using Sniffin’ Sticks Identification, and 8.90±5.14 using the questionnaire for olfactory disorders-negative statements. Conclusion In chronic rhinosinusitis populations, a significant percentage of patients experience olfactory dysfunction and mean olfactory scores are within the dysosmic range. PMID:27873345

To cross-culturally adapt the Achilles tendon Total Rupture Score (ATRS) to Persian language and to preliminary evaluate the reliability and validity of a Persian ATRS. A cross-sectional and prospective cohort study was conducted to translate and cross-culturally adapt the ATRS to Persian language (ATRS-Persian) following steps described in guidelines. Thirty patients with total Achilles tendon rupture and 30 healthy subjects participated in this study. Psychometric properties of floor/ceiling effects (responsiveness), internal consistency reliability, test-retest reliability, standard error of measurement (SEM), smallest detectable change (SDC), construct validity, and discriminant validity were tested. Factor analysis was performed to determine the ATRS-Persian structure. There were no floor or ceiling effects that indicate the content and responsiveness of ATRS-Persian. Internal consistency was high (Cronbach's α 0.95). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.58-0.95). The test-retest reliability was excellent [(ICC)agreement 0.98]. SEM and SDC were 3.57 and 9.9, respectively. Construct validity was supported by a significant correlation between the ATRS-Persian total score and the Persian Foot and Ankle Outcome Score (PFAOS) total score and PFAOS subscales (r = 0.55-0.83). The ATRS-Persian significantly discriminated between patients and healthy subjects. Explanatory factor analysis revealed 1 component. The ATRS was cross-culturally adapted to Persian and demonstrated to be a reliable and valid instrument to measure functional outcomes in Persian patients with Achilles tendon rupture. II.

To evaluate the relationship between the severity of bronchiectatic diseases, as evident on high-resolution computed tomography (HRCT) and the patient's quality of life measured using the St George's Respiratory Questionnaire (SGRQ). Forty-six patients (25 women, 21 men, mean age: 63 years) with bronchiectatic disease as evident on recent HRCT examinations were recruited. Each patient completed the SGRQ and underwent respiratory function tests. HRCT findings were blindly and independently scored by two radiologists, using the modified Bhalla scoring system. The relationships between HRCT scores, SGRQ scores and pulmonary function tests were evaluated. The patients' total CT score did not correlate with the SGRQ scores. However, patients with more advanced disease on HRCT, significantly differed in their SGRQ scores from patients with milder bronchiectatic disease. A significant correlation was found between the CT scores for the middle and distal lung zones and the activity, impacts and total SGRQ scores. No correlation was found between CT scores and respiratory function test indices. However, a significant correlation was found between the SGRQ scores and most of the respiratory function test indices. A correlation between the severity of bronchiectatic disease as expressed in HRCT and the health-related quality of life exists in patients with a more severe bronchiectatic disease but not in patients with mild disease. Such correlation depends on the location of the bronchiectasis in the pulmonary tree.

To date, the comprehensive geriatric assessment (CGA) does not include an evaluation tool for handicap. To develop a new instrument for assessing handicap in the elderly: the Geriatric Handicap Scale (GHS). 656 community-dwelling elderly were enrolled in this study. We identified the thematic areas investigated by the CGA which showed a significant correlation with the handicap condition (handicap yes/not) to be included in our scale (Phase 1). Afterwards, we evaluated the possible correlations between: (1) the score obtained in each area of GHS and those obtained in CGA tests investigating similar dimensions, (2) GHS total score and the Multidimensional Prognostic Index (MPI) total score (Phase 2). In Phase 1, data analysis showed several significant correlations between the handicap condition and the scores obtained to the CGA tests exploring cognition, mood, functional impairment, comorbidity, social and environmental variables. Thus, we developed a tool considering five variables: (1) cognition and mood; (2) functional impairment; (3) hearing/visual impairment; (4) any additional comorbidity factors; (5) environmental/social risk factors. In Phase 2, data analysis showed significant correlations between the score obtained in each area of GHS and those obtained in the CGA tests investigating similar dimensions. A positive correlation between GHS total score and MPI total score (r = 68; p = 0.001) was also reported. Cut-off score for the GHS was established. Psychometric properties of GHS were also investigated and adequate estimates of internal reliability were demonstrated. Our tool could prove useful to correctly categorize the disadvantageous condition related to patient's disability.

To design and test a simple, easily modifiable system for calculating faculty productivity in teaching, research, administration, and patient care in which all areas of endeavor would be recognized and high productivity in one area would produce results similar to high productivity in another at the Louisiana State University School of Medicine in New Orleans. A relative-value and time-based system was designed in 1996 so that similar efforts in the four areas would produce similar scores, and a profile reflecting the authors' estimates of high productivity ("super faculty") was developed for each area. The activity profiles of 17 faculty members were used to test the system. "Super-faculty" scores in all areas were similar. The faculty members' mean scores were higher for teaching and research than for administration and patient care, and all four mean scores were substantially lower than the respective totals for the "super faculty". In each category the scores of those faculty members who scored above the mean in that category were used to calculate new mean scores. The mean scores for these faculty members were similar to those for the "super faculty" in teaching and research but were substantially lower for administration and patient care. When the mean total score of the eight faculty members predicted to have total scores below the group mean was compared with the mean total score of the nine faculty members predicted to have total scores above the group mean, the difference was significant (p < .0001). For the former, every score in each category was below the mean, with the exception of one faculty member's score in one category. Of the latter, eight had higher scores in teaching and four had higher scores in teaching and research combined. This system provides a quantitative method for the equal recognition of faculty productivity in a number of areas, and it may be useful as a starting point for other academic units exploring similar issues.

2016-12-01

Despite the availability of various field-tests for many competitive sports, a reliable and valid test specifically developed for use in men's gymnastics has not yet been developed. The Men's Gymnastics Functional Measurement Tool (MGFMT) was designed to assess sport-specific physical abilities in male competitive gymnasts. The purpose of this study was to develop the MGFMT by establishing a scoring system for individual test items and to initiate the process of establishing test-retest reliability and construct validity. A total of 83 competitive male gymnasts ages 7-18 underwent testing using the MGFMT. Thirty of these subjects underwent re-testing one week later in order to assess test-retest reliability. Construct validity was assessed using a simple regression analysis between total MGFMT scores and the gymnasts' USA-Gymnastics competitive level to calculate the coefficient of determination (r 2 ). Test-retest reliability was analyzed using Model 1 Intraclass correlation coefficients (ICC). Statistical significance was set at the p<0.05 level. The relationship between total MGFMT scores and subjects' current USA-Gymnastics competitive level was found to be good (r 2  = 0.63). Reliability testing of the MGFMT composite test score showed excellent test-retest reliability over a one-week period (ICC = 0.97). Test-retest reliability of the individual component tests ranged from good to excellent (ICC = 0.75-0.97). The results of this study provide initial support for the construct validity and test-retest reliability of the MGFMT. Level 3.

Women with early-stage breast cancer, of whom only 15% will experience a recurrence, are often conflicted or uncertain about taking chemotherapy. Gene expression profiling (GEP) of tumours informs risk prediction, potentially affecting treatment decisions. We examined whether receiving a GEP test score reduces decisional conflict in chemotherapy treatment decision making. A general population sample of 200 women completed the decisional conflict scale (DCS) at baseline (no GEP test score scenario) and after (scenario with GEP test score added) completing a discrete choice experiment survey for early-stage breast cancer chemotherapy. We scaled the 16-item DCS total scores and subscores from 0 to 100 and calculated means, standard deviations and change in scores, with significance (p < 0.05) based on matched pairs t-tests. We identified five respondent subgroups based on preferred treatment option; almost 40% did not change their chemotherapy decision after receiving GEP testing information. Total score and all subscores (uncertainty, informed, values clarity, support, and effective decision) decreased significantly in the respondent subgroup who were unsure about taking chemotherapy initially but changed to no chemotherapy (n =33). In the subgroup of respondents (n = 25) who chose chemotherapy initially but changed to unsure, effective decision subscore increased significantly. In the overall sample, changes in total and all subscores were non-significant. GEP testing adds value for women initially unsure about chemotherapy treatment with a decrease in decisional conflict. However, for women who are confident about their treatment decisions, GEP testing may not add value. Decisions to request GEP testing should be personalised based on patient preferences.

We investigated the prevalence and correlates of comorbid depression among patients with internet gaming disorder using the Internet Gaming Disorder scale (IGD-9) and the Patient Health Questionnaire-9 (PHQ-9) among nonclinical online survey respondents. Korean adolescents and adults from 14 to 39 years of age were selected. We compared internet gaming use patterns and sociodemographic and clinical variables between patients with internet gaming disorder who had depression and those without depression. In 2016, 7200 people participated in an online survey. Respondents with internet gaming disorder that was comorbid with depression were older, more often female, had greater Internet Addiction Test total scores, Alcohol Use Disorder Identification Test total scores, Generalized Anxiety Disorder Scale-7 total scores, Fagerstrom Test for Nicotine Dependence total scores, and higher Dickman Dysfunctional Impulsivity Instrument dysfunctional subscale scores than those without depression. The binary logistic regression analysis revealed that female gender, problematic alcohol use, anxiety, and a past history of psychiatric counseling or treatment due to internet gaming use were significant predictors for comorbid depression among participants with internet gaming disorder. Depression was a common comorbidity of internet gaming disorder. Internet gaming disorder with comorbid depression was related to more serious psychiatric phenomenology and a greater psychiatric burden. Copyright © 2017. Published by Elsevier B.V.

To test the applicability of the Environmental Scoring System, a quick and simple approach for quantitatively measuring environmental triggers collected during home visits, and to evaluate its contribution to improving asthma outcomes among various child asthma programs. We pooled and analyzed data from multiple child asthma programs in the Greater Boston Area, Massachusetts, collected in 2011 to 2016, to examine the association of environmental scores (ES) with measures of asthma outcomes and compare the results across programs. Our analysis showed that demographics were important contributors to variability in asthma outcomes and total ES, and largely explained the differences among programs at baseline. Among all programs in general, we found that asthma outcomes were significantly improved and total ES significantly reduced over visits, with the total Asthma Control Test score negatively associated with total ES. Our study demonstrated that the Environmental Scoring System is a useful tool for measuring home asthma triggers and can be applied regardless of program and survey designs, and that demographics of the target population may influence the improvement in asthma outcomes.

Errors in judgment during thyroidectomy can lead to recurrent laryngeal nerve injury and other complications. Despite the strong link between patient outcomes and intraoperative decision-making, methods to evaluate these complex skills are lacking. The purpose of this study was to develop objective metrics to evaluate advanced cognitive skills during thyroidectomy and to obtain validity evidence for them. An interactive online learning platform was developed ( www.thinklikeasurgeon.com ). Trainees and surgeons from four institutions completed a 33-item assessment, developed based on a cognitive task analysis and expert Delphi consensus. Sixteen items required subjects to make annotations on still frames of thyroidectomy videos, and accuracy scores were calculated based on an algorithm derived from experts' responses ("visual concordance test," VCT). Seven items were short answer (SA), requiring users to type their answers, and scores were automatically calculated based on their similarity to a pre-populated repertoire of correct responses. Test-retest reliability, internal consistency, and correlation of scores with self-reported experience and training level (novice, intermediate, expert) were calculated. Twenty-eight subjects (10 endocrine surgeons and otolaryngologists, 18 trainees) participated. There was high test-retest reliability (intraclass correlation coefficient = 0.96; n = 10) and internal consistency (Cronbach's α = 0.93). The assessment demonstrated significant differences between novices, intermediates, and experts in total score (p < 0.01), VCT score (p < 0.01) and SA score (p < 0.01). There was high correlation between total case number and total score (ρ = 0.95, p < 0.01), between total case number and VCT score (ρ = 0.93, p < 0.01), and between total case number and SA score (ρ = 0.83, p < 0.01). This study describes the development of novel metrics and provides validity evidence for an interactive Web-based platform to objectively assess decision-making during thyroidectomy.

New strategies for selection and training of physicians are emerging. Previous studies have demonstrated a correlation between visual-spatial ability and visual working memory with surgical simulator performance. The aim of this study was to perform a detailed analysis on how these abilities are associated with metrics in simulator performance with different task content. The hypothesis is that the importance of visual-spatial ability and visual working memory varies with different task contents. Twenty-five medical students participated in the study that involved testing visual-spatial ability using the MRT-A test and visual working memory using the RoboMemo computer program. Subjects were also trained and tested for performance in three different surgical simulators. The scores from the psychometric tests and the performance metrics were then correlated using multivariate analysis. MRT-A score correlated significantly with the performance metrics Efficiency of screening (p = 0.006) and Total time (p = 0.01) in the GI Mentor II task and Total score (p = 0.02) in the MIST-VR simulator task. In the Uro Mentor task, both the MRT-A score and the visual working memory 3-D cube test score as presented in the RoboMemo program (p = 0.02) correlated with Total score (p = 0.004). In this study we have shown that some differences exist regarding the impact of visual abilities and task content on simulator performance. When designing future cognitive training programs and testing regimes, one might have to consider that the design must be adjusted in accordance with the specific surgical task to be trained in mind.

This manuscript presents a translation and adaptation of the Common Object Token (COT) test, which assesses speech perception, into the Sinhalese language and an attempt to validate it for use on children with normal hearing (NH) and children with a cochlear implant (CI). Ninety-five children (70 with NH, 25 with a CI) participated in the study. The COT test was translated, back-translated, and evaluated by a team of experts until the Sinhalese translation was deemed acceptable. Data of Sinhalese children with NH and values of children with a CI were analysed. Internal reliability and consistency of the COT total score were determined. Lastly, a quick version of the COT test was created. The total mean scores and subtest mean scores improved with age for children with NH. For children with a CI, a strong relationship between the COT total score and device experience, i.e. hearing age, was found. A Quick Sinhalese COT test version, suitable for children with a CI, could be created from Subtests 2, 3, and 4. The Sinhalese COT test is valid for assessing the age-related development of speech perception and identification skills of children with NH. Results suggest that the COT is valid for use in children with a CI. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The Tokyo Autistic Behavior Scale (TABS) consisting of 39 items provisionally grouped in four areas--interpersonal-social relationship, language-communication, habit-mannerism and others--is an instrument used by a child's caretaker to rate the child's autistic behaviors on a 3-point scale. Test-retest reliability was satisfactory (i.e., an r for a total score was .94). Among six DSM-III diagnostic groups, infantile autism showed a significantly higher total TABS score than the other five groups, and a taxonomic validity coefficient was .54. An r between total scores of the TABS and the Childhood Autism Rating Scale--Tokyo Version was .59. The area scores showed a lower validity than the total score. The TABS appears to be a useful instrument to assess autistic behavior.

Sadler, Philip Michael

1992-01-01

This study of 1,414 high school earth science and astronomy students characterizes the prevalence of their astronomical misconceptions. The multiple-choice instrument was prepared by scouring the literature on scientific misconceptions for evidence of preconceptions and from the author's interviews with students. Views that were incorrect, but espoused by a large fraction of students, were included as distractors. Results have been analyzed using classical test theory. A linear multiple regression model has helped to show the relative contributions of demographic and school factors to the number of misconceptions held by students. The instrument was found to be a reliable and valid test of students' misconceptions. The mean student score was 34 percent. Fifty-one student misconceptions were revealed by this test, nineteen of which were preferred by students to the correct answer. Several misconceptions appeared more frequently among the higher-performing students. Significant differences in student performance were found in several subgroups based upon schooling and demographic factors. Twenty -five percent out of a total of 30 percent of the variance in total test score could be accounted for by gender, race, and math level courses taken. Grade level and previous enrollment in an earth science course were not found to be predictive of total score. Mother's education proved to be of small import; level of father's education was not significant. This test is a useful addition to instruments that measure student misconceptions. It could find application in tests of effective intervention for conceptual learning. Significantly shortened versions of this instrument that account for 75 and 90 percent of the variance in the forty-seven-item instrument are recommended. Such tests of misconceptions may be somewhat disheartening to teachers and their students. A test made up of only misconception questions will probably have average total scores less than 40 percent. If teachers are to test their students using misconception questions, they should adjust grading policies to reflect this lower average score.

In-training examination (ITE) is a cognitive examination similar to the written test, but it is different from the Clinical Practice Examination of the Korean Academy of Family Medicine (KAFM) Certification Examination (CE). The objective of this is to estimate the positive predictive value of the KAFM-ITE for identifying residents at risk for poor performance on the three types of KAFM-CE. 372 residents who completed the KAFM-CE in 2011 were included. We compared the mean KAFM-CE scores with ITE experience. We evaluated the correlation and the positive predictive value (PPV) of ITE for the multiple choice question (MCQ) scores of 1st written test & 2nd slide examination, the total clinical practice examination scores, and the total sum of 2nd test. 275 out of 372 residents completed ITE. Those who completed ITE had significantly higher MCQ scores of 1st written test than those who did not. The correlation of ITE scores with 1st written MCQ (0.627) was found to be the highest among the other kinds of CE. The PPV of the ITE score for 1st written MCQ scores was 0.672. The PPV of the ITE score ranged from 0.376 to 0.502. The score of the KAFM ITE has acceptable positive predictive value that could be used as a part of comprehensive evaluation system for residents in cognitive field.

The Trail Making Test is a popular neuropsychological test and its interpretation has traditionally used time-based scores. This study examined an alternative approach to scoring that is simply based on the examinees' ability to complete the test. If an examinee is able to complete Trails B successfully, they are coded as "completers"; if not, they are coded as "noncompleters." To assess this approach to scoring Trails B, the performance of 97 diagnostically heterogeneous individuals referred for a dementia evaluation was examined. In this sample, 55 individuals successfully completed Trails B and 42 individuals were unable to complete it. Point-biserial correlations indicated a moderate-to-strong association (r(pb)=.73) between the Trails B completion variable and the Total Scale score of the Repeatable Battery for the Assessment of Neurological Status (RBANS), which was larger than the correlation between the Trails B time-based score and the RBANS Total Scale score (r(pb)=.60). As a screen for dementia status, Trails B completion showed a sensitivity of 69% and a specificity of 100% in this sample. These results suggest that dichotomous scoring of Trails B might provide a brief and clinically useful measure of dementia status.

Purpose/Background Despite the availability of various field-tests for many competitive sports, a reliable and valid test specifically developed for use in men's gymnastics has not yet been developed. The Men's Gymnastics Functional Measurement Tool (MGFMT) was designed to assess sport-specific physical abilities in male competitive gymnasts. The purpose of this study was to develop the MGFMT by establishing a scoring system for individual test items and to initiate the process of establishing test-retest reliability and construct validity. Methods A total of 83 competitive male gymnasts ages 7-18 underwent testing using the MGFMT. Thirty of these subjects underwent re-testing one week later in order to assess test-retest reliability. Construct validity was assessed using a simple regression analysis between total MGFMT scores and the gymnasts’ USA-Gymnastics competitive level to calculate the coefficient of determination (r2). Test-retest reliability was analyzed using Model 1 Intraclass correlation coefficients (ICC). Statistical significance was set at the p<0.05 level. Results The relationship between total MGFMT scores and subjects’ current USA-Gymnastics competitive level was found to be good (r2 = 0.63). Reliability testing of the MGFMT composite test score showed excellent test-retest reliability over a one-week period (ICC = 0.97). Test-retest reliability of the individual component tests ranged from good to excellent (ICC = 0.75-0.97). Conclusions The results of this study provide initial support for the construct validity and test-retest reliability of the MGFMT. Level of Evidence Level 3 PMID:27999723

A comparison of hands-on inquiry instruction to lectureinstruction with special needs high school biology students

NASA Astrophysics Data System (ADS)

Jensen-Ruopp, Helga Spitko

A comparison of hands-on inquiry instruction with lecture instruction was presented to 134 Patterns and Process Biology students. Students participated in seven biology lessons that were selected from Biology Survey of Living Things (1992). A pre and post paper and pencil assessment was used as the data collecting instrument. The treatment group was taught using hands-on inquiry strategies while the non-treatment group was taught in the lecture method of instruction. The team teaching model was used as the mode of presentation to the treatment group and the non-treatment group. Achievement levels using specific criterion; novice (0% to 50%), developing proficiency (51% to 69%), accomplished (70% to 84) and exceptional or mastery level (85% to 100%) were used as a guideline to tabulate the results of the pre and post assessment. Rubric tabulation was done to interpret the testing results. The raw data was plotted using percentage change in test score totals versus reading level score by gender as well as percentage change in test score totals versus auditory vocabulary score by gender. Box Whisker plot comparative descriptive of individual pre and post test scores for the treatment and non-treatment group was performed. Analysis of covariance (ANCOVA) using MINITAB Statistical Software version 14.11 was run on data of the seven lessons, as well as on gender (male results individual and combined, and female results individual and combined) results. Normal Probability Plots for total scores as well as individual test scores were performed. The results suggest that hands-on inquiry based instruction when presented to special needs students including; at-risk; English as a second language limited, English proficiency and special education inclusive students' learning may enhance individual student achievement.

This study tested the reliability and subtraction frequency of the study model-scoring system of the American Board of Orthodontists (ABO). We used a sample of 36 posttreatment study models that were selected randomly from six different orthodontic offices. Intrajudge and interjudge reliability was calculated using nonparametric statistics (Spearman rank coefficient, Wilcoxon, Kruskal-Wallis, and Mann-Whitney tests). We found differences ranging from 3 to 6 subtraction points (total score) for intrajudge scoring between two sessions. For overall total ABO score, the average correlation was .77. Intrajudge correlation was greatest for occlusal relationships and least for interproximal contacts. Interjudge correlation for ABO score averaged r = .85. Correlation was greatest for buccolingual inclination and least for overjet. The data show that some judges, on average, were much more lenient than others and that this resulted in a range of total scores between 19.7 and 27.5. Most of the deductions were found in the buccal segments and most were related to the second molars. We present these findings in the context of clinicians preparing for the ABO phase III examination and for orthodontists in their ongoing evaluation of clinical results.

Objective The Adult Myopathy Assessment Tool (AMAT) is a 13-item performance-based battery developed to assess functional status and muscle endurance. The purpose of this study was to determine the intrarater and interrater reliability of the AMAT in adults with myosits. Methods Nineteen raters (13 physical therapists and 6 physicians) scored videotaped recordings of patients with myositis performing the AMAT for a total of 114 tests and 1,482 item observations per session. Raters rescored the AMAT test and item observations during a follow up session (19 ±6 days between scoring sessions). All raters completed a single, self-directed, electronic training module prior to the initial scoring session. Results Intrarater and interrater reliability correlation coefficients were .94 or greater for the AMAT Functional Subscale, Endurance Subscale, and Total score (all p < 0.02 for Ho:ρ ≤ 0.75). All AMAT items had satisfactory intrarater agreement (Kappa statistics with Fleiss-Cohen weights, Kw = .57-1.00). Interrater agreement was acceptable for each AMAT item (K = .56-.89) except the sit up (K = .16). The standard error of measurement and 95% confidence interval range for the AMAT Total scores did not exceed 2 points across all observations (AMAT Total score range = 0-45). Conclusions The AMAT is a reliable, domain-specific assessment of functional status and muscle endurance for adult subjects with myositis. Results of this study suggest that physicians and physical therapists may reliably score the AMAT following a single training session. The AMAT Functional Subscale, Endurance Subscale, and Total score exhibit interrater and intrarater reliability suitable for clinical and research use. PMID:25201624

The purpose of this randomized controlled study was to explore the effectiveness of an educational intervention on nurses' attitudes and knowledge regarding pain management and to explore associations with nurses' characteristics. A four Solomon group experimental design was employed to assess the effect of the intervention and potential effects of pre-intervention testing. One hundred and twelve nurses were randomized to two intervention and two control groups. The intervention was based on viewing a series of educational videotapes and case scenarios. The Validated Hellenic version of the Nurses Knowledge and Attitudes Survey Regarding Pain (GV-NKASRP) was used. Pre-intervention scores revealed various limitations in regard to pain assessment and management. At the pre-test, the average number of correct answers was 17.58+/-7.58 (45.1%+/-19.3% of total questions). Pre-intervention scores differed significantly among participants with different educational backgrounds (P < 0.0001). A significant effect of pain education on total knowledge scores as well as regarding specific questions was detected. Intervention group participants provided 6.11+/-5.55 additional correct answers (15.66%+/-14.23% improvement, P < 0.0001), and they exhibited significantly improved post-test scores compared to controls (26.49+/-5.24 vs. 18.75+/-4.48; P < 0.0001). A potential negative effect of pre-test on knowledge gain for specific items and for total scores was detected. These findings suggest low pre-test knowledge scores among Hellenic oncology nurses and a significant effect of the intervention.

Purpose To describe a method for monitoring progression of glaucoma using the multifocal visual evoked potential (mfVEP) technique. Methods Eighty-seven patients diagnosed with open-angle glaucoma were divided into two groups. Group I, comprised 43 patients who had a repeat mfVEP test within 50 days (mean 0.9 ± 0.5 months), and group II, 44 patients who had a repeat test after at least 6 months (mean 20.7 ± 9.7 months). Monocular mfVEPs were obtained using a 60-sector pattern reversal dartboard display. Monocular and interocular analyses were performed. Data from the two visits were compared. The total number of abnormal test points with P < 5% within the visual field (total scores) and number of abnormal test points within a cluster (cluster size) were calculated. Data for group I provided a measure of test–retest variability independent of disease progression. Data for group II provided a possible measure of progression. Results The difference in the total scores for group II between visit 1 and visit 2 for the interocular and monocular comparison was significant (P < 0.05) as was the difference in cluster size for the interocular comparison (P < 0.05). Group I did not show a significant change in either total score or cluster size. Conclusion The change in the total score and cluster size over time provides a possible method for assessing progression of glaucoma with the mfVEP technique. PMID:18830654

To study relationship between the cognitive and the non-cognitive symptoms of delirium. Eighty-four patients referred to psychiatry liaison services and met DSM-IVTR criteria of delirium were assessed using the Delirium Rating Scale Revised-1998 (DRSR-98) and Cognitive Test for Delirium (CTD). The mean DRS-R-98 severity score was 17.19 and DRS-R-98 total score was 23.36. The mean total score on CTD was 11.75. The mean scores on CTD were highest for comprehension (3.47) and lowest for vigilance (1.71). Poor attention was associated with significantly higher motor retardation and higher DRS-R-98 severity scores minus the attention scores. There were no significant differences between those with and without poor attention. Higher attention deficits were associated with higher dysfunction on all other domains of cognition on CTD. There was significant correlation between cognitive functions as assessed on CTD and total DRS-R-98 score, DRS-R-98 severity score and DRS-R-98 severity score without the attention item score. However, few correlations emerged between CTD domains and CTD total scores with cognitive symptom total score of DRS-R-98 (items 9-13) and non-cognitive symptom total score of DRS-R-98 (items 1-8). Our study suggests that in delirium, cognitive deficits are quite prevalent and correlate with overall severity of delirium. Attention deficit is a core symptom of delirium.

BACKGROUND: The Balance Evaluation Systems Test (BESTest) was recently created to allow the development of treatments according to the specific balance system affected in each patient. The Brazilian version of the BESTest has not been specifically tested after stroke. OBJECTIVE: To evaluate the intra- and inter-rater reliability and concurrent and convergent validity of the total score of the BESTest and BESTest sections for adults with hemiparesis after stroke. METHOD: The study included 16 subjects (61.1±7.5 years) with chronic hemiparesis (54.5±43.5 months after stroke). The BESTest was administered by two raters in the same week and one of the raters repeated the test after a one-week interval. Intraclass correlation coefficient (ICC) was calculated to assess intra- and interrater reliability. Concurrent validity with the Berg Balance Scale (BBS) and convergent validity with the Activities-specific Balance Confidence scale (ABC-Brazil) were assessed using Pearson's correlation coefficient. RESULTS: Both the BESTest total score (ICC=0.98) and the BESTest sections (ICC between 0.85 and 0.96) have excellent intrarater reliability. Interrater reliability for the total score was excellent (ICC=0.93) and, for the sections, it ranged between 0.71 and 0.94. The correlation coefficient between the BESTest and the BBS and ABC-Brazil were 0.78 and 0.59, respectively. CONCLUSIONS: The Brazilian version of the BESTest demonstrated adequate reliability when measured by sections and could identify what balance system was affected in patients after stroke. Concurrent validity was excellent with the BBS total score and good to excellent with the sections. The total scores but not the sections present adequate convergent validity with the ABC-Brazil. However, other psychometric properties should be further investigated. PMID:25003281

To test the hypotheses that community-dwelling veterans with spinal cord injury (SCI) who receive the Wheelchair Skills Training Program (WSTP) in their own environments significantly improve their manual wheelchair-skills capacity, retain those improvements at one year and improve participation in comparison with an Educational Control (EC) group. We carried out a randomized controlled trial, studying 106 veterans with SCI from three Veterans Affairs rehabilitation centers. Each participant received either five one-on-one WSTP or EC sessions 30-45 minutes in duration. The main outcome measures were the total and subtotal percentage capacity scores from the Wheelchair Skills Test 4.1 (WST) and Craig Handicap Assessment and Reporting Technique (CHART) scores. Participants in the WSTP group improved their total and Advanced-level WST scores by 7.1% and 30.1% relative to baseline (p < 0.001) and retained their scores at one year follow-up. The success rates for individual skills were consistent with the total and subtotal WST scores. The CHART Mobility sub-score improved by 3.2% over baseline (p = 0.021). Individualized wheelchair skills training in the home environment substantially improves the advanced and total wheelchair skills capacity of experienced community-dwelling veterans with SCI but has only a small impact on participation.

To test the reliability and validity of two mental workload assessment scales, i.e. subjective workload assessment technique (SWAT) and NASA task load index (NASA-TLX). One thousand two hundred and sixty-eight mental workers were sampled from various kinds of occupations, such as scientific research, education, administration and medicine, etc, with randomized cluster sampling. The re-test reliability, split-half reliability, Cronbach's alpha coefficient and correlation coefficients between item score and total score were adopted to test the reliability. The test of validity included structure validity. The re-test reliability coefficients of these two scales and their items were ranged from 0.516 to 0.753 (P < 0.01), indicating the two scales had good re-test reliability; the split-half reliability of SWAT was 0.645, and its Cronbach's alpha coefficient was more than 0.80, all the correlation coefficients between its items score and total score were more than 0.70; as for NASA-TLX, both the split-half reliability and Cronbach's alpha coefficient were more than 0.80, the correlation coefficients between its items score and total score were all more than 0.60 (P < 0.01) except the item of performance. Both scales had good inner consistency. The Pearson correlation coefficient between the two scales was 0.492 (P < 0.01), implying the results of the two scales had good consistency. Factor analysis showed that the two scales had good structure validity. Both SWAT and NASA-TLX have good reliability and validity and may be used as a valid tool to assess mental workload in China after being revised properly.

The aim of this research is to investigate if two additional interventions, test and reflection, after standard cardiopulmonary resuscitation (CPR) training facilitate learning by comparing 13-year-old students' practical skills and willingness to act. Seventh grade students in council schools of two municipalities in south-east Sweden. School classes were randomised to CPR training only (O), CPR training with a practical test including feedback (T) or CPR training with reflection and a practical test including feedback (RT). Measures of practical skills and willingness to act in a potential life-threatening situation were studied directly after training and at 6 months using a digital reporting system and a survey. A modified Cardiff test was used to register the practical skills, where scores in each of 12 items resulted in a total score of 12-48 points. The study was conducted in accordance with current European Resuscitation Council guidelines during December 2013 to October 2014. 29 classes for a total of 587 seventh grade students were included in the study. The total score of the modified Cardiff test at 6 months was the primary outcome. Secondary outcomes were the total score directly after training, the 12 individual items of the modified Cardiff test and willingness to act. At 6 months, the T and O groups scored 32 (3.9) and 30 (4.0) points, respectively (p<0.001), while the RT group scored 32 (4.2) points (not significant when compared with T). There were no significant differences in willingness to act between the groups after 6 months. A practical test including feedback directly after training improved the students' acquisition of practical CPR skills. Reflection did not increase further CPR skills. At 6-month follow-up, no intervention effect was found regarding willingness to make a life-saving effort. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Translation and adaptation of the fatigue severity scale for use in Portugal.

PubMed

Laranjeira, Carlos António

2012-08-01

The Fatigue Severity Scale (FSS) is a widely used instrument to measure the impact of fatigue on specific types of functioning. This study aims to translate and test the reliability and validity of the Portuguese version of the FSS. The questionnaire was administered to a worker sample of 424 nurses. Reliability analysis showed satisfactory results (Cronbach's alpha coefficient = .87). The test-retest reliability was .85. The principal component analysis showed that the FSS was a measure with a one-factor structure. The construct validity of the total FSS score was assessed by correlation with Maslach Burnout Inventory (MBI) score, Depression Anxiety Stress Scale (DASS) score, and Visual Analogue Scale (VAS) score. Each of the corresponding correlation coefficients among the total FSS score and MBI score, DASS score, and perceived fatigue score (VAS) were .55 (p < .01), .62 (p < .01), and .68 (p < .01), respectively, which shows sufficient construct validity. To measure the discriminant validity of FSS, we examined the differences in scores between groups in terms of the number of hours of sleep and overtime. The less nurses slept and the longer they worked, the higher their total FSS score became. This preliminary validation study of the Portuguese version of FSS proved that it is an acceptable, reliable, and valid measure of fatigue in the working population. Copyright © 2012 Elsevier Inc.

Repeated measurements of episodic memory are needed for monitoring amnestic mild cognitive impairment (aMCI) and mild Alzheimer's disease (AD). Most episodic memory tests may pose a challenge to patients, even when they are in the milder stages of the disease. This cross-sectional study compared floor effects of the Visual Association Test (VAT) and the Rey Auditory Verbal Learning Test (RAVLT) in healthy elderly controls and in patients with aMCI or AD (N = 125). A hierarchical multiple regression analysis was used to examine whether linear or quadratic trends best fitted the data of cognitive test performance across global cognitive impairment. Results showed that VAT total scores decreased linearly across the range of global cognitive impairment, whereas RAVLT total scores showed a quadratic trend, with total scores levelling off for 90% of aMCI patients and 94% of AD patients. We conclude that the VAT shows few if any floor effects in patients with aMCI and mild AD and is therefore a potentially promising cognitive test for monitoring episodic memory impairment.

There is currently no published information on the validity and reliability of the Golombok Rust Inventory of Sexual Satisfaction in the Asian population, specifically in patients with stress urinary incontinence, which limits its use in this region. Our study aimed to evaluate the psychometric properties of this questionnaire in the Malaysian population. Ten couples were recruited for the pilot testing. The agreement between the English and Chinese or Malay versions were tested using the intraclass correlation coefficients, with results of more than 0.80 for all subscales and overall scores indicating good agreement. Sixty-six couples were included in the subsequent phase. The following data are presented in the order of English, Chinese, and Malay. Cronbach's alphas for the male total score were 0.82, 0.88, and 0.95. For the female total score, Cronbach's alphas were 0.76, 0.78, and 0.88. Intraclass correlation coefficients for the male total score were 0.93, 0.94, and 0.99, while intraclass correlation coefficients for the female total score were 0.89, 0.86, and 0.88. In conclusion, the English, Chinese, and Malay versions each proved to be valid and reliable in our Malaysian population.

A balanced diet informed by sound nutrition knowledge is key for operational readiness and the health of military personnel. Unfortunately, research suggests that military personnel have inadequate dietary intakes. This study assessed general nutrition knowledge, diet quality and their association in Australian military personnel. A convenience sample of male military personnel (n 211) including Army soldiers and officers completed a validated general nutrition knowledge questionnaire (GNKQ) and FFQ. The GNKQ assessed knowledge of dietary guidelines (Section A), sources of nutrients (Section B), choosing everyday foods (Section C) and diet-disease relationships (Section D). The Australian Recommended Food Score (ARFS) was used to assess diet quality from FFQ data. Statistical analyses included the χ 2 test, Spearman's correlation test, t test, median test, ANCOVA and ordinal logistic regression. The mean total GNKQ score was 52·7 %. Participants performed best on Section A (58·5 %) followed by Sections B (57·3 %) and C (57·0 %) and worst on Section D (31·0 %). Overall, officers scored significantly higher than soldiers (58·7 v. 51·9 %, P=0·001). Age was weakly but positively correlated with GNKQ total scores (r 0·307; P<0·0005), with no significant effects seen for level of education (P=0·463) or living arrangement (P=0·167). Overall ARFS was 37·6 (sd 7·7) (50·8 %) with officers scoring significantly higher than soldiers (54·7 v. 50·3 %, P=0·040). No demographic variables influenced total ARFS. The total GNKQ score had a significant, positive but weak relationship with total ARFS (r 0·179; P=0·009). Given the importance of nutrition to personnel health and operational readiness, initiatives to improve nutrition knowledge and diet quality are recommended in this population, especially in soldiers.

Several authors have tested the accuracy of the Total Body Score (TBS) method for quantifying decomposition, but none have examined the reliability of the method as a scoring system by testing interobserver error rates. Sixteen participants used the TBS system to score 59 observation packets including photographs and written descriptions of 13 human cadavers in different stages of decomposition (postmortem interval: 2-186 days). Data analysis used a two-way random model intraclass correlation in SPSS (v. 17.0). The TBS method showed "almost perfect" agreement between observers, with average absolute correlation coefficients of 0.990 and average consistency correlation coefficients of 0.991. While the TBS method may have sources of error, scoring reliability is not one of them. Individual component scores were examined, and the influences of education and experience levels were investigated. Overall, the trunk component scores were the least concordant. Suggestions are made to improve the reliability of the TBS method. © 2016 American Academy of Forensic Sciences.

This study examined the ability of computerized maze test performance to predict the road test performance of cognitively impaired and normal older drivers. The authors examined 133 older drivers, including 65 with probable Alzheimer disease, 23 with possible Alzheimer disease, and 45 control subjects without cognitive impairment. Subjects completed 5 computerized maze tasks employing a touch screen and pointer as well as a battery of standard neuropsychological tests. Parameters measured for mazes included errors, planning time, drawing time, and total time. Within 2 weeks, subjects were examined by a professional driving instructor on a standardized road test modeled after the Washington University Road Test. Road test total score was significantly correlated with total time across the 5 mazes. This maze score was significant for both Alzheimer disease subjects and control subjects. One maze in particular, requiring less than 2 minutes to complete, was highly correlated with driving performance. For the standard neuropsychological tests, highest correlations were seen with Trail Making A (TrailsA) and the Hopkins Verbal Learning Tests Trial 1 (HVLT1). Multiple regression models for road test score using stepwise subtraction of maze and neuropsychological test variables revealed significant independent contributions for total maze time, HVLT1, and TrailsA for the entire group; total maze time and HVLT1 for Alzheimer disease subjects; and TrailsA for normal subjects. As a visual analog of driving, a brief computerized test of maze navigation time compares well to standard neuropsychological tests of psychomotor speed, scanning, attention, and working memory as a predictor of driving performance by persons with early Alzheimer disease and normal elders. Measurement of maze task performance appears to be useful in the assessment of older drivers at risk for hazardous driving. PMID:18287166

Detecting Intervention Effects in a Cluster-Randomized Design Using Multilevel Structural Equation Modeling for Binary Responses.

Cho, Sun-Joo; Preacher, Kristopher J; Bottge, Brian A

2015-11-01

Multilevel modeling (MLM) is frequently used to detect group differences, such as an intervention effect in a pre-test-post-test cluster-randomized design. Group differences on the post-test scores are detected by controlling for pre-test scores as a proxy variable for unobserved factors that predict future attributes. The pre-test and post-test scores that are most often used in MLM are summed item responses (or total scores). In prior research, there have been concerns regarding measurement error in the use of total scores in using MLM. To correct for measurement error in the covariate and outcome, a theoretical justification for the use of multilevel structural equation modeling (MSEM) has been established. However, MSEM for binary responses has not been widely applied to detect intervention effects (group differences) in intervention studies. In this article, the use of MSEM for intervention studies is demonstrated and the performance of MSEM is evaluated via a simulation study. Furthermore, the consequences of using MLM instead of MSEM are shown in detecting group differences. Results of the simulation study showed that MSEM performed adequately as the number of clusters, cluster size, and intraclass correlation increased and outperformed MLM for the detection of group differences.

The aim of this study was to evaluate the value of conventional factors, the Risk Assessment and Predictor Tool (RAPT) and performance-based functional tests as predictors of delayed recovery after total hip arthroplasty (THA). A prospective cohort study in a regional hospital in the Netherlands with 315 patients was attending for THA in 2012. The dependent variable recovery of function was assessed with the Modified Iowa Levels of Assistance scale. Delayed recovery was defined as taking more than 3 days to walk independently. Independent variables were age, sex, BMI, Charnley score, RAPT score and scores for four performance-based tests [2-minute walk test, timed up and go test (TUG), 10-meter walking test (10 mW) and hand grip strength]. Regression analysis with all variables identified older age (>70 years), Charnley score C, slow walking speed (10 mW >10.0 s) and poor functional mobility (TUG >10.5 s) as the best predictors of delayed recovery of function. This model (AUC 0.85, 95% CI 0.79-0.91) performed better than a model with conventional factors and RAPT scores, and significantly better (p = 0.04) than a model with only conventional factors (AUC 0.81, 95% CI 0.74-0.87). The combination of performance-based tests and conventional factors predicted inpatient functional recovery after THA. Two simple functional performance-based tests have a significant added value to a more conventional screening with age and comorbidities to predict recovery of functioning immediately after total hip surgery. Patients over 70 years old, with comorbidities, with a TUG score >10.5 s and a walking speed >1.0 m/s are at risk for delayed recovery of functioning. Those high risk patients need an accurate discharge plan and could benefit from targeted pre- and postoperative therapeutic exercise programs.

To determine the measurement properties and diagnostic utility of the JFK Coma Recovery Scale-Revised (CRS-R). Analysis of interrater and test-retest reliability, internal consistency, concurrent validity, and diagnostic accuracy. Acute inpatient brain injury rehabilitation hospital. Convenience sample of 80 patients with severe acquired brain injury admitted to an inpatient Coma Intervention Program with a diagnosis of either vegetative state (VS) or minimally conscious state (MCS). Not applicable. The CRS-R, the JFK Coma Recovery Scale (CRS), and the Disability Rating Scale (DRS). Interrater and test-retest reliability were high for CRS-R total scores. Subscale analysis showed moderate to high interrater and test-retest agreement although systematic differences in scoring were noted on the visual and oromotor/verbal subscales. CRS-R total scores correlated significantly with total scores on the CRS and DRS indicating acceptable concurrent validity. The CRS-R was able to distinguish 10 patients in an MCS who were otherwise misclassified as in a VS by the DRS. The CRS-R can be administered reliably by trained examiners and repeated measurements yield stable estimates of patient status. CRS-R subscale scores demonstrated good agreement across raters and ratings but should be used cautiously because some scores were underrepresented in the current study. The CRS-R appears capable of differentiating patients in an MCS from those in a VS.

Fl oor effects are present in most dementia assessment tools as dementia progresses and the in-depth assessment of patients considered more or less on vegetative state is questionable. To develop a questionnaire (the "Gatos Clinical Test-GCT") for the assessment of end-stage demented patients. Five hundred patients with dementia of various causes and an MMSE score between 0 and 2 were enrolled in the study. The GCT consists of 14 closed type questions rated on a Likert scale. The total score is used to evaluate patient's dementia. Various aspects of validity and reliability (including face, content and structural validity as well as test-retest reliability) were examined. Three subscales "Autonomy/Alertness", "Gnosias" and "Somatokinetic function" were defined, with a Cronbach equal to 0.851, 0.756 and 0.598 respectively. The GCT subscales and total score were statistically significant higher in patients with MMSE score 1 or 2 compared with those with MMSE score 0 (p<0.0005). Patients with GCT total score less than 12.5 had 75% probability to have zero MMSE score. The "GATOS" questionnaire is a valid and reliable test for patients with severe dementia, aiming at identification of those patients who could sustain some quality of life. It is a relatively short and easy to administer tool. As dementia prevalence is expected to rise further worldwide we believe that GCT could offer valuable services to health professionals, caregivers and patients.

The Developmental Eye Movement (DEM) test is commonly used as a clinical visual-verbal ocular motor assessment tool to screen and diagnose reading problems at the onset. No established norm exists for using the DEM test with Mandarin Chinese-speaking Chinese children. This study aims to establish the normative values of the DEM test for the Mandarin Chinese-speaking population in China; it also aims to compare the values with three other published norms for English-, Spanish-, and Cantonese-speaking Chinese children. A random stratified sampling method was used to recruit children from eight kindergartens and eight primary schools in the main urban and suburban areas of Nanjing. A total of 1,425 Mandarin Chinese-speaking children aged 5 to 12 years took the DEM test in Mandarin Chinese. A digital recorder was used to record the process. All of the subjects completed a symptomatology survey, and their DEM scores were determined by a trained tester. The scores were computed using the formula in the DEM manual, except that the "vertical scores" were adjusted by taking the vertical errors into consideration. The results were compared with the three other published norms. In our subjects, a general decrease with age was observed for the four eye movement indexes: vertical score, adjusted horizontal score, ratio, and total error. For both the vertical and adjusted horizontal scores, the Mandarin Chinese-speaking children completed the tests much more quickly than the norms for English- and Spanish-speaking children. However, the same group completed the test slightly more slowly than the norms for Cantonese-speaking children. The differences in the means were significant (P<0.001) in all age groups. For several ages, the scores obtained in this study were significantly different from the reported scores of Cantonese-speaking Chinese children (P<0.005). Compared with English-speaking children, only the vertical score of the 6-year-old group, the vertical-horizontal time ratio of the 8-year-old group and the errors of 9-year-old group had no significant difference (P>0.05); compared with Spanish-speaking children, the scores were statistically significant (P<0.001) for the total error scores of the age groups, except the 6-, 9-, 10-, and 11-year-old age groups (P>0.05). DEM norms may be affected by differences in language, cultural, and educational systems among various ethnicities. The norms of the DEM test are proposed for use with Mandarin Chinese-speaking children in Nanjing and will be proposed for children throughout China.

Background In-training examination (ITE) is a cognitive examination similar to the written test, but it is different from the Clinical Practice Examination of the Korean Academy of Family Medicine (KAFM) Certification Examination (CE). The objective of this is to estimate the positive predictive value of the KAFM-ITE for identifying residents at risk for poor performance on the three types of KAFM-CE. Methods 372 residents who completed the KAFM-CE in 2011 were included. We compared the mean KAFM-CE scores with ITE experience. We evaluated the correlation and the positive predictive value (PPV) of ITE for the multiple choice question (MCQ) scores of 1st written test & 2nd slide examination, the total clinical practice examination scores, and the total sum of 2nd test. Results 275 out of 372 residents completed ITE. Those who completed ITE had significantly higher MCQ scores of 1st written test than those who did not. The correlation of ITE scores with 1st written MCQ (0.627) was found to be the highest among the other kinds of CE. The PPV of the ITE score for 1st written MCQ scores was 0.672. The PPV of the ITE score ranged from 0.376 to 0.502. Conclusion The score of the KAFM ITE has acceptable positive predictive value that could be used as a part of comprehensive evaluation system for residents in cognitive field. PMID:22745873

A digital analysis that is shown to be accurate will ease the demonstration of initial case complexity. To date, no literature exists on the accuracy of the digital American Board of Orthodontics Discrepancy Index (DI) calculations when applied to pretreatment digital models. Plaster models were obtained from 45 previous patients with varying degrees of malocclusion. Total DI scores and the target disorders were computed manually with a periodontal probe on the original plaster casts (gold standard) and digitally using Ortho Insight 3D (Motion View Software, Hixson, Tenn) and OrthoCAD (Cadent, Carlstadt, NJ). Intrarater and interrater reliabilities were assessed for 15 subjects using the Spearman rho correlation test. Accuracies of the DI scores and target disorders were assessed for all 45 subjects using Wilcoxon signed ranks tests. Intrarater and interrater reliabilities were high for total DI scores and most target disorders (r > 0.8). No significant difference was found between total DI score when measured with OrthoCAD compared with manual calculations. The total DI scores calculated by Ortho Insight 3D were found to be significantly greater than those by manual calculation by 2.71 points. The findings indicate that a DI calculated by Ortho Insight 3D may lead the clinician to overestimate case complexity. OrthoCAD's DI module was demonstrated to be a clinically acceptable alternative to manual calculation of the total scores. Copyright © 2015 American Association of Orthodontists.

The purpose of this study was to understand changes in knowledge and opinions of underserved American Indian and Hispanic high school students after attending a 2-week summer pipeline program using and testing a pre/postsurvey. The research aims were to (a) psychometrically analyze the survey to determine if scale items could be summed to create a total scale score or subscale scores; (b) assess change in scores pre/postprogram; and (c) examine the survey to make suggestions for modifications and further testing to develop a valid tool to measure changes in student perceptions about going to college and nursing as a result of pipeline programs. Psychometric analysis indicated poor model fit for a 1-factor model for the total scale and majority of subscales. Nonparametric tests indicated statistically significant increases in 13 items and decreases in 2 items. Therefore, while total scores or subscale scores cannot be used to assess changes in perceptions from pre- to postprogram, the survey can be used to examine changes over time in each item. Student did not have an accurate view of nursing and college and underestimated support needed to attend college. However students realized that nursing was a profession with autonomy, respect, and honor. Copyright © 2016 Elsevier Inc. All rights reserved.

The purpose of this study was to assess the impact of bronchiectasis, anxiety and depression, and parameters of disease severity on health-related quality of life (HRQOL) in subjects with COPD. Sixty-two subjects with stable COPD were selected for the study. The presence of bronchiectasis in all subjects with COPD was investigated by high-resolution computed tomography. Pulmonary function tests were performed. Dyspnea was assessed using the Modified Medical Research Council (MMRC) dyspnea scale. Psychological disorders were investigated using the Hospital Anxiety and Depression Scale (HADS), and the HRQOL was examined using the St George Respiratory Questionnaire (SGRQ). High-resolution computed tomography revealed that 44 of 62 (70.9%) subjects with COPD had bronchiectasis. There were no differences in pulmonary function tests, symptoms, activities, impact, SGRQ total scores, and HADS scores between COPD subjects with and without bronchiectasis. Pearson correlation analyses showed that there was no significant association between the presence of bronchiectasis, bronchial wall thickness, or severity of bronchial dilatation and all subscales of the SGRQ or HADS scores. Additionally, HADS scores showed significant positive association with all subscales of the SGRQ in all subjects. In linear regression analysis, a statistically significant relationship was found between the SGRQ total score and percent-of-predicted FEV1, percent-of-predicted diffusing capacity of the lung for carbon monoxide, MMRC score, and anxiety score, but the SGRQ total score was not associated with age, body mass index, total number of hospitalizations, PaO2 , or depression score. The presence of bronchiectasis in subjects with COPD does not impact HRQOL and psychological disorders. However, disease severity, dyspnea levels, and anxiety scores predict poor HRQOL.

The purpose of the present study was to investigate the possible effects of sociocultural influences, specifically pertaining to language and education, on baseline neuropsychological concussion testing as obtained via immediate postconcussion assessment and cognitive testing (ImPACT) of players from a professional baseball team. A retrospective chart review. Baseline testing of a professional baseball organization. Four hundred five professional baseball players. Age, languages spoken, hometown country location (United States/Canada vs overseas), and years of education. The 5 ImPACT composite scores (verbal memory, visual memory, visual motor speed, reaction time, impulse control) and ImPACT total symptom score from the initial baseline testing. The result of t tests revealed significant differences (P < 0.05) when comparing native English to native Spanish speakers in many scores. Even when corrected for education, the significant differences (P < 0.05) remained in some scores. Sociocultural differences may result in differences in computer-based neuropsychological testing scores.

Background The inFLUenza Patient Reported Outcome (FLU-PRO) measure is a daily diary assessing signs/symptoms of influenza across six body systems: Nose, Throat, Eyes, Chest/Respiratory, Gastrointestinal, Body/Systemic, developed and tested in adults with influenza. Objectives This study tested the reliability, validity, and responsiveness of FLU-PRO scores in adults with influenza-like illness (ILI). Methods Data from the prospective, observational study used to develop and test the FLU-PRO in influenza virus positive patients were analyzed. Adults (≥18 years) presenting with influenza symptoms in outpatient settings in the US, UK, Mexico, and South America were enrolled, tested for influenza virus, and asked to complete the 37-item draft FLU-PRO daily for up to 14-days. Analyses were performed on data from patients testing negative. Reliability of the final, 32-item FLU-PRO was estimated using Cronbach’s alpha (α; Day 1) and intraclass correlation coefficients (ICC; 2-day reproducibility). Convergent and known-groups validity were assessed using patient global assessments of influenza severity (PGA). Patient report of return to usual health was used to assess responsiveness (Day 1–7). Results The analytical sample included 220 ILI patients (mean age = 39.3, 64.1% female, 88.6% white). Sixty-one (28%) were hospitalized at some point in their illness. Internal consistency reliability (α) of FLU-PRO Total score was 0.90 and ranged from 0.72–0.86 for domain scores. Reproducibility (Day 1–2) was 0.64 for Total, ranging from 0.46–0.78 for domain scores. Day 1 FLU-PRO scores correlated (≥0.30) with the PGA (except Gastrointestinal) and were significantly different across PGA severity groups (Total: F = 81.7, p<0.001; subscales: F = 6.9–62.2; p<0.01). Mean score improvements Day 1–7 were significantly greater in patients reporting return to usual health compared with those who did not (p<0.05, Total and subscales, except Gastrointestinal and Eyes). Conclusions Results suggest FLU-PRO scores are reliable, valid, and responsive in adults with influenza-like illness. PMID:29566007

Home Observation for Measurement of the Environment (HOME) was designed to reflect parental support of early cognitive and socioemotional development. 12-month HOME scores were correlated with elementary school achievement, 5--9 years later. 50 low-income children were rank ordered by a weighted average of centile estimates of achievement test scores, letter grades, and curriculum levels in reading and math. 24 children were classified as having significant school achievement problems. The HOME total score correlated significantly, r = .37, with school centile scores among the low-income families. The statistically more appropriate contingency table analysis revealed a 68% correct classification rate and a significantly reduced error rate over random or blanket prediction. The results supported the predictive value of the 12-month HOME for school achievement among low-income families. In an additional sample of 21 middle-income families, there was insufficient variability among HOME scores to allow prediction. The HOME total scores were highly correlated, r = .86, among siblings tested at least 10 months apart.

The aim of this study was to document receptive and expressive language levels and reading skills achieved by Mandarin-speaking children who had received cochlear implants (CIs) and used them for 4.75-7.42 years. The effects of possible associated factors were also analyzed. Standardized Mandarin language and reading tests were administered to 39 prelingually deaf children with Nucleus 24 devices. The Mandarin Chinese version of the Peabody Picture Vocabulary Test was used to assess their receptive vocabulary knowledge and the Revised Primary School Language Assessment Test for their receptive and expressive language skills. The Graded Chinese Character Recognition Test was used to test their written word recognition ability and the Reading Comprehension Test for their reading comprehension ability. Raw scores from both language and reading measurements were compared to normative data of nor- mal-hearing children to obtain standard scores. The results showed that the mean standard score for receptive vocabulary measurement and the mean T scores for the receptive language, expressive language and total language measurement were all in the low-average range in comparison to the normative sample. In contrast, the mean T scores for word and text reading comprehension were almost the same as for their age-matched hearing counterparts. Among all children with CIs, 75.7% scored within or above the normal range of their age-matched hearing peers on receptive vocabulary measurement. For total language, Chinese word recognition and reading scores, 71.8, 77 and 82% of children with CIs were age appropriate, respectively. A strong correlation was found between language and reading skills. Age at implantation and sentence perception scores account for 37% of variance for total language outcome. Sentence perception scores and preimplantation residual hearing were revealed to be associated with the outcome of reading comprehension. We concluded that by using standard tests, the language development and reading skill of Mandarin-speaking children who use CIs from a young age appear to fall within the normal range of their hearing age mates, at least after 4.8-7.4 years of experience. However, to fully evaluate the fine linguistic skills of these subjects, a more detailed study and longer follow-up period are needed. Copyright © 2010 S. Karger AG, Basel.

Most research examining the predictive validity of the Medical College Admission Test (MCAT) has focused on the relationship between MCAT scores and scores on the United States Medical Licensing Examination Step exams. This study examined whether MCAT scores predict students' unimpeded progress toward graduation (UP), which the authors defined as not withdrawing or being dismissed for academic reasons, graduating within five years of matriculation, and passing the Step 1, Step 2 Clinical Knowledge, and Step 2 Clinical Skills exams on the first attempt. Students who matriculated during 2001-2004 at 119 U.S. medical schools were included in the analyses. Logistic regression analyses were used to estimate the relationships between UP and MCAT total scores alone, undergraduate grade point averages (UGPAs) alone, and UGPAs and MCAT total scores together. All analyses were conducted at the school level and were considered together to evaluate relationships across schools. The majority of matriculants experienced UP. Together, UGPAs and MCAT total scores predicted UP well. MCAT total scores alone were a better predictor than UGPAs alone. Relationships were similar across schools; however, there was more variability across schools in the relationship between UP and UGPAs than between UP and MCAT total scores. The combination of UGPAs and MCAT total scores performs well as a predictor of UP. Both UGPAs and MCAT total scores are strong predictors of academic performance in medical school through graduation, not just the first two years. Further, these relationships generalize across medical schools.

Multilevel modeling (MLM) is frequently used to detect group differences, such as an intervention effect in a pre-test–post-test cluster-randomized design. Group differences on the post-test scores are detected by controlling for pre-test scores as a proxy variable for unobserved factors that predict future attributes. The pre-test and post-test scores that are most often used in MLM are summed item responses (or total scores). In prior research, there have been concerns regarding measurement error in the use of total scores in using MLM. To correct for measurement error in the covariate and outcome, a theoretical justification for the use of multilevel structural equation modeling (MSEM) has been established. However, MSEM for binary responses has not been widely applied to detect intervention effects (group differences) in intervention studies. In this article, the use of MSEM for intervention studies is demonstrated and the performance of MSEM is evaluated via a simulation study. Furthermore, the consequences of using MLM instead of MSEM are shown in detecting group differences. Results of the simulation study showed that MSEM performed adequately as the number of clusters, cluster size, and intraclass correlation increased and outperformed MLM for the detection of group differences.

In an effort to empower nursing students to successfully persist in chemistry, predictors of success for undergraduate nursing students enrolled in a one-semester organic and biochemistry course were identified. The sample consisted of 308 undergraduate nursing students enrolled in Chemistry 108 (Principles of Organic and Biochemistry) during a period of seven semesters. In this study, Supplemental Instruction (SI) is a nonremedial academic support program offered for Chemistry 108 students. Placement tests in Mathematics, Reading, and English are required of all entering students. The English Placement Test assesses proficiency in analytical reading and writing; the Nelson Denny Reading Test (Form E) assesses the student's understanding of written vocabulary and the mastery of reading comprehension, and the Mathematics Placement Test measures the student's mastery of arithmetic and algebraic calculations. Both demographic and academic variables were examined. For the entire sample, five predictor variables were identified: Mathematics Placement Test score, Chemistry 107 grade (a prerequisite), total number of SI sessions attended, Nelson Denny Reading Test (Form E) score, and age. Predictors for various subpopulations of the sample were also identified. Predictors for students of traditional age were Mathematics Placement Test score, total number of SI sessions attended, and Chemistry 107 grade. The best predictors for continuing education students were Chemistry 107 grade and Nelson Denny Test score.

The impact of stroke on emotional intelligence

PubMed Central

2010-01-01

Background Emotional intelligence (EI) is important for personal, social and career success and has been linked to the frontal anterior cingulate, insula and amygdala regions. Aim To ascertain which stroke lesion sites impair emotional intelligence and relation to current frontal assessment measurements. Methods One hundred consecutive, non aphasic, independently functioning patients post stroke were evaluated with the Bar-On emotional intelligence test, "known as the Emotional Quotient Inventory (EQ-i)" and frontal tests that included the Wisconsin Card Sorting Test (WCST) and Frontal Systems Behavioral Inventory (FRSBE) for correlational validity. The results of a screening, bedside frontal network syndrome test (FNS) and NIHSS to document neurological deficit were also recorded. Lesion location was determined by the Cerefy digital, coxial brain atlas. Results After exclusions (n = 8), patients tested (n = 92, mean age 50.1, CI: 52.9, 47.3 years) revealed that EQ-i scores were correlated (negatively) with all FRSBE T sub-scores (apathy, disinhibition, executive, total), with self-reported scores correlating better than family reported scores. Regression analysis revealed age and FRSBE total scores as the most influential variables. The WCST error percentage T score did not correlate with the EQ-i scores. Based on ANOVA, there were significant differences among the lesion sites with the lowest mean EQ-i scores associated with temporal (71.5) and frontal (87.3) lesions followed by subtentorial (91.7), subcortical gray (92.6) and white (95.2) matter, and the highest scores associated with parieto-occipital lesions (113.1). Conclusions 1) Stroke impairs EI and is associated with apathy, disinhibition and executive functioning. 2) EI is associated with frontal, temporal, subcortical and subtentorial stroke syndromes.

As simulator fidelity (i.e., realism) increases from low to high, the simulator more closely resembles the real environment, but it also becomes more expensive. It is generally assumed that the use of high-fidelity simulators results in better learning; however, the effect of fidelity on learning non-technical skills (NTS) is unknown. This was a non-inferiority trial comparing the efficacy of high- vs low-fidelity simulators on learning NTS. Thirty-six postgraduate medical trainees were recruited for the trial. During the pre-test phase, the trainees were randomly assigned to manage a scenario using either a high-fidelity simulator (HFS) or a low-fidelity simulator (LFS), followed by expert debriefing. All trainees then underwent a video recorded post-test scenario on a HFS, and the NTS were assessed between the two groups. The primary outcome was the overall post-test Ottawa Global Rating Scale (OGRS), while controlling for overall pre-test OGRS scores. Non-inferiority between the LFS and HFS was based on a non-inferiority margin of greater than 1. For our primary outcome, the mean (SD) post-test overall OGRS score was not significantly different between the HFS and LFS groups after controlling for pre-test overall OGRS scores [3.8 (0.9) vs 4.0 (0.9), respectively; mean difference, 0.2; 95% confidence interval, -0.4 to 0.8; P = 0.48]. For our secondary outcomes, the post-test total OGRS score was not significantly different between the HFS and LFS groups after controlling for pre-test total OGRS scores (P = 0.33). There were significant improvements in mean overall (P = 0.01) and total (P = 0.003) OGRS scores from pre-test to post-test. There were no significant associations between postgraduate year (P = 0.82) and specialty (P = 0.67) on overall OGRS performance. This study suggests that low-fidelity simulators are non-inferior to the more costly high-fidelity simulators for teaching NTS to postgraduate medical trainees.

Academic dishonesty, including cheating and plagiarism, is on the rise in colleges, particularly among engineering students. While students decide to engage in these behaviors for many different reasons, academic integrity training can help improve their understanding of ethical decision making. The two studies outlined in this paper assess the effectiveness of an online module in increasing academic integrity among first semester engineering students. Study 1 tested the effectiveness of an academic honesty tutorial by using a between groups design with a Time 1- and Time 2-test. An academic honesty quiz assessed participants' knowledge at both time points. Study 2, which incorporated an improved version of the module and quiz, utilized a between groups design with three assessment time points. The additional Time 3-test allowed researchers to test for retention of information. Results were analyzed using ANCOVA and t tests. In Study 1, the experimental group exhibited significant improvement on the plagiarism items, but not the total score. However, at Time 2 there was no significant difference between groups after controlling for Time 1 scores. In Study 2, between- and within-group analyses suggest there was a significant improvement in total scores, but not plagiarism scores, after exposure to the tutorial. Overall, the academic integrity module impacted participants as evidenced by changes in total score and on specific plagiarism items. Although future implementation of the tutorial and quiz would benefit from modifications to reduce ceiling effects and improve assessment of knowledge, the results suggest such tutorial may be one valuable element in a systems approach to improving the academic integrity of engineering students.

2014-01-01

The Psychometric Entrance Test (PET), used for admission to higher education in Israel together with the Matriculation (Bagrut), had in the past one general (total) score in which the weights for its domains: Verbal, Quantitative and English, were 2:2:1, respectively. In 2011, two additional total scores were introduced, with different weights for the Verbal and the Quantitative domains. This study compares the predictive validity of the three general scores of PET, and demonstrates validity in terms of utility. 100,863 freshmen students of all Israeli universities over the classes of 2005-2009. Regression weights and correlations of the predictors with FYGPA were computed. Simulations based on these results supplied the utility estimates. On average, PET is slightly more predictive than the Bagrut; using them both yields a better tool than either of them alone. Assigning differential weights to the components in the respective schools further improves the validity. The introduction of the new general scores of PET is validated by gathering and analyzing evidence based on relations of test scores to other variables. The utility of using the test can be demonstrated in ways different from correlations.

This study was performed to determine the relationship between undergraduate academic performance and total Medical College Admission Test score and academic performance in the podiatric medical program at Des Moines University. The allopathic and osteopathic medical professions have published educational research examining this relationship. To our knowledge, no such educational research has been published for podiatric medical education. The undergraduate cumulative and science grade point averages and total Medical College Admission Test scores of four podiatric medical classes (2007-2010, N = 169) were compared with their academic performance in the first 2 years of podiatric medical school using pairwise Pearson product moment correlations and multiple regression analysis. Significant low to moderate positive correlations were identified between undergraduate cumulative and science grade point averages and student academic performance in years 1 and 2 of podiatric medical school for each of the four classes (except one) and the pooled data. There was no significant correlation between Medical College Admission Test score and academic performance in years 1 and 2 (except one) and the pooled data. These results identify undergraduate cumulative grade point average as the strongest cognitive admissions variable in predicting academic performance in the podiatric medicine program at Des Moines University, followed by undergraduate science grade point average. These results also suggest limitations of the total Medical College Admission Test score in predicting academic performance. Information from this study can be used in the admissions process and to monitor student progress.

Numerous studies have reported that maternal cigarette smoking during pregnancy is related to lower IQ scores in the offspring. Confounding is a crucial issue in interpreting this association. In the US National Longitudinal Survey of Youth 1979, IQ was ascertained serially during childhood using the Peabody Individual Achievement Test, the total score for which comprises results on 3 subtests: mathematics, reading comprehension, and reading recognition. Maternal IQ was assessed by using the Armed Forces Qualification Test. There were 5578 offspring (born to 3145 mothers) with complete information for maternal smoking habits, total Peabody Individual Achievement Test score, and covariates. The offspring of mothers who smoked > or = 1 pack of cigarettes per day during pregnancy had an IQ score (Peabody Individual Achievement Test total) that was, on average, 2.87 points lower than children born to nonsmoking mothers. Separate control for maternal education (0.27-IQ-point decrement) and, to a lesser degree, maternal IQ (1.51-IQ-point decrement) led to marked attenuation of the maternal-smoking-offspring-IQ relation. A similar pattern of results was seen when Peabody Individual Achievement Test subtest results were the outcomes of interest. The only exception was the Peabody Individual Achievement Test mathematics score, in which adjusting for maternal IQ essentially led to complete attenuation of the maternal-smoking-offspring-IQ gradient (0.66-IQ-point decrement). The impact of controlling for physical, behavioral, and other social indices was much less pronounced than for maternal education or IQ. These findings suggest that previous studies that did not adjust for maternal education and/or IQ may have overestimated the association of maternal smoking with offspring cognitive ability.

Assessing the Medication Adherence App Marketplace From the Health Professional and Consumer Vantage Points

PubMed Central

2017-01-01

Background Nonadherence produces considerable health consequences and economic burden to patients and payers. One approach to improve medication nonadherence that has gained interest in recent years is the use of smartphone adherence apps. The development of smartphone adherence apps has increased rapidly since 2012; however, literature evaluating the clinical app and effectiveness of smartphone adherence apps to improve medication adherence is generally lacking. Objective The aims of this study were to (1) provide an updated evaluation and comparison of medication adherence apps in the marketplace by assessing the features, functionality, and health literacy (HL) of the highest-ranking adherence apps and (2) indirectly measure the validity of our rating methodology by determining the relationship between our app evaluations and Web-based consumer ratings. Methods Two independent reviewers assessed the features and functionality using a 4-domain rating tool of all adherence apps identified based on developer claims. The same reviewers downloaded and tested the 100 highest-ranking apps including an additional domain for assessment of HL. Pearson product correlations were estimated between the consumer ratings and our domain and total scores. Results A total of 824 adherence apps were identified; of these, 645 unique apps were evaluated after applying exclusion criteria. The median initial score based on descriptions was 14 (max of 68; range 0-60). As a result, 100 of the highest-scoring unique apps underwent user testing. The median overall user-tested score was 31.5 (max of 73; range 0-60). The majority of the user tested the adherence apps that underwent user testing reported a consumer rating score in their respective online marketplace. The mean consumer rating was 3.93 (SD 0.84). The total user-tested score was positively correlated with consumer ratings (r=.1969, P=.04). Conclusions More adherence apps are available in the Web-based marketplace, and the quality of these apps varies considerably. Consumer ratings are positively but weakly correlated with user-testing scores suggesting that our rating tool has some validity but that consumers and clinicians may assess adherence app quality differently.

Background Assessing residents’ understanding and application of the 6 intrinsic CanMEDS roles (communicator, professional, manager, collaborator, health advocate, scholar) is challenging for postgraduate medical educators. We hypothesized that an objective structured clinical examination (OSCE) designed to assess multiple intrinsic CanMEDS roles would be sufficiently reliable and valid. Methods The OSCE comprised 6 10-minute stations, each testing 2 intrinsic roles using case-based scenarios (with or without the use of standardized patients). Residents were evaluated using 5-point scales and an overall performance rating at each station. Concurrent validity was sought by correlation with in-training evaluation reports (ITERs) from the last 12 months and an ordinal ranking created by program directors (PDs). Results Twenty-five residents from postgraduate years (PGY) 0, 3 and 5 participated. The interstation reliability for total test scores (percent) was 0.87, while reliability for each of the communicator, collaborator, manager and professional roles was greater than 0.8. Total test scores, individual station scores and individual CanMEDS role scores all showed a significant effect by PGY level. Analysis of the PD rankings of intrinsic roles demonstrated a high correlation with the OSCE role scores. A correlation was seen between ITER and OSCE for the communicator role, while the ITER medical expert and total scores highly correlated with the communicator, manager and professional OSCE scores. Conclusion An OSCE designed to assess the intrinsic CanMEDS roles was sufficiently valid and reliable for regular use in an orthopedic residency program. PMID:25078926

Psychometric testing of the Persian version of Pain Anxiety Symptom Scale 20. The aim of this study was to assess the reliability and construct validity of the PASS-20 in nonspecific chronic low back pain (LBP) patients. The PASS-20 is a self-report questionnaire that assesses pain-related anxiety. The Psychometric properties of this instrument have not been assessed in Persian-speaking chronic LBP patients. One hundred and sixty participants with chronic LBP completed the Persian version of PASS-20, Tampa Scale of Kinesiophobia (TSK), Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), trait form of the State-Trait Anxiety (STAI-T), Oswestry Low Back Pain Disability Index (ODI), Beck Depression Inventory (BDI-II), and Visual Analogue Scale (VAS). To evaluate test-retest reliability, 60 patients filled out the PASS-20, 6 to 8 days after the first visit. Test-retest reliability (intraclass correlation coefficient [ICC], standard error of measurement [SEM], and minimal detectable change [MDC]), internal consistency, dimensionality, and construct validity were examined. The ICCs of the PASS-20 subscales and total score ranged from 0.71 to 0.8. The SEMs for PASS-20 total score was 7.29 and for the subscales ranged from 2.43 to 2.98. The MDC for the total score was 20.14 and for the subscales ranged from 6.71 to 8.23. The Cronbach alpha values for the subscales and total score ranged from 0.70 to 0.91. Significant positive correlations were found between the PASS-20 total score and PCS, TSK, FABQ, ODI, BDI, STAI-T, and pain intensity. The Persian version of the PASS-20 showed acceptable psychometric properties for the assessment of pain-related anxiety in Persian-speaking patients with chronic LBP. 3.

Our goal was to validate an instrument with which terminally ill patients could evaluate the quality of care they receive at the end of life (EOL). Questionnaire development followed a four-phase process: item generation and reduction, construction, pilot testing, and field-testing. Using relevance and priority criteria and pilot testing, we developed a 16-item questionnaire. Factor analyses of data from 235 patients resulted in the Quality Care Questionnaire-End of Life (QCQ-EOL) covering dignity-conserving care, care by health care professionals, individualised care, and family relationships. All subscales and total scores showed high internal consistency (Cronbach alpha range, 0.73-0.89). The ability of total score and selective subscale scores clearly differentiated patients on the basis of clinical situation, sense of dignity, and general rating of care quality. Correlations of scores between patients and caregivers were substantial. The QCQ-EOL can be adopted to assess the quality of care received by terminally ill patients.

Abstract Background: The aim of the study was to assess whether an inexpensive tablet-based box trainer (TBT) is at least equally effective compared with a standard box trainer (SBT) to learn basic laparoscopic skills (BLS). BLS training outside the operating room has been shown to be beneficial for surgical residency. However, simulation trainers are expensive and are not consistently available in all training centers. Therefore, TBT and other homemade box trainers were developed. Methods: Medical students were randomized to either a TBT or an SBT and trained 4 fundamentals of laparoscopic surgery (FLS) tasks for 1 hour twice a week for 4 weeks. A baseline test before the training period and a posttraining test were performed. All students then completed a questionnaire to assess their assigned box trainer. The primary outcome measure was the improvement in total test scores. Improvement in the scores for the 4 individual FLS tasks was chosen as a secondary outcome measure. Results: Thirty-two medical students were recruited. Baseline test scores did not differ significantly between the groups. BLS improved significantly in both groups for the total score and for all 4 tasks separately. Participants in the TBT group showed a greater improvement of total scores than those in the SBT group, although this did not reach statistical significance; noninferiority of the TBT compared with the SBT concerning the improvement of total scores could be demonstrated. Regarding the individual FLS tasks, noninferiority of the TBT could be shown for the pattern cutting and the suturing with intracorporeal knot-tying task. The acceptance of the TBT by the trainees was very good. Conclusion: Learning BLS on a homemade TBT is at least equally effective as on an SBT, with the advantage of being very cost saving. Therefore, this readily available box trainer may be used as an effective, flexible training device outside the operating room to improve accessibility to simulation training. PMID:27684813

Errors in judgment during laparoscopic cholecystectomy can lead to bile duct injuries and other complications. Despite correlations between outcomes, expertise and advanced cognitive skills, current methods to evaluate these skills remain subjective, rater- and situation-dependent and non-systematic. The purpose of this study was to develop objective metrics using a Web-based platform and to obtain validity evidence for their assessment of decision-making during laparoscopic cholecystectomy. An interactive online learning platform was developed ( www.thinklikeasurgeon.com ). Trainees and surgeons from six institutions completed a 12-item assessment, developed based on a cognitive task analysis. Five items required subjects to draw their answer on the surgical field, and accuracy scores were calculated based on an algorithm derived from experts' responses ("visual concordance test", VCT). Test-retest reliability, internal consistency, and correlation with self-reported experience, Global Operative Assessment of Laparoscopic Skills (GOALS) score and Objective Performance Rating Scale (OPRS) score were calculated. Questionnaires were administered to evaluate the platform's usability, feasibility and educational value. Thirty-nine subjects (17 surgeons, 22 trainees) participated. There was high test-retest reliability (intraclass correlation coefficient = 0.95; n = 10) and internal consistency (Cronbach's α = 0.87). The assessment demonstrated significant differences between novices, intermediates and experts in total score (p < 0.01) and VCT score (p < 0.01). There was high correlation between total case number and total score (ρ = 0.83, p < 0.01) and between total case number and VCT (ρ = 0.82, p < 0.01), and moderate to high correlations between total score and GOALS (ρ = 0.66, p = 0.05), VCT and GOALS (ρ = 0.83, p < 0.01), total score and OPRS (ρ = 0.67, p = 0.04), and VCT and OPRS (ρ = 0.78, p = 0.01). Most subjects agreed or strongly agreed that the platform and assessment was easy to use [n = 29 (78 %)], facilitates learning intra-operative decision-making [n = 28 (81 %)], and should be integrated into surgical training [n = 28 (76 %)]. This study provides preliminary validity evidence for a novel interactive platform to objectively assess decision-making during laparoscopic cholecystectomy.

Psychometric evaluation of the impact of weight on quality of life-lite questionnaire (IWQOL-lite) in a community sample.

The short form of impact of weight on quality of life (IWQOL)-Lite is a 31-item, self-report, obesity-specific measure of health-related quality of life (HRQOL) that consists of a total score and scores on each of five scales--physical function, self-esteem, sexual life, public distress, and work--and that exhibits strong psychometric properties. This study was undertaken in order to assess test-retest reliability and discriminant validity in a heterogeneous sample of individuals not in treatment. Individuals were recruited from the community to complete questionnaires that included the IWQOL-Lite, SF-36, Rosenberg self-esteem (RSE) scale, Marlowe-Crowne social desirability scale, global ratings of quality of life, and sexual functioning and public distress ratings. Persons currently enrolled in weight loss programs or with a body mass index (BMI) of less than 18.5 were dropped from the analyses, leaving 341 females and 153 males for analysis, with an average BMI of 27.4. For test-retest reliability, 112 participants completed the IWQOL-Lite again. ANOVA revealed significant main effects for BMI for all IWQOL-Lite scales and total score. Females showed greater impairment than males on all scales except public distress. Internal consistency ranged from 0.816 to 0.944 for IWQOL-Lite scales and was 0.958 for total score. Test-retest reliability ranged from 0.814 to 0.877 for scales and was 0.937 for total score. Internal consistency and test-retest results for overweight/obese subjects were similar to those obtained for the total sample. There was strong evidence for convergent and discriminant validity of the IWQOL-Lite in overweight/obese subjects. As in previous studies conducted on treatment-seeking obese persons, the IWQOL-Lite appears to be a reliable and valid measure of obesity-specific quality of life in overweight/obese persons not seeking treatment.

In this study, we investigated the reliability of the Nociception Coma Scale which has recently been developed to assess nociception in non-communicative, severely brain-injured patients. Prospective cross-sequential study. Semi-intensive care unit and long-term brain injury care. Forty-four patients diagnosed as being in a vegetative state (n=26) or in a minimally conscious state (n=18). Patients were assessed by two experts (rater A and rater B) on two consecutive weeks to measure inter-rater agreement and test-retest reliability. Total scores and subscores of the Nociception Coma Scale. We performed a total of 176 assessments. The inter-rater agreement was moderate for the total scores (k = 0.57) and fair to substantial for the subscores (0.33 ≤ k ≤ 0.62) on week 2. The test-retest reliability was substantial for the total scores (k = 0.66) and moderate to almost perfect for the subscores (0.53 ≤ k ≤ 0.96) for rater A. The inter-rater agreement was weaker on week 1, whereas the test-retest reliability was lower for the least experienced rater (rater B). This study provides further evidence of the psychometric qualities of the Nociception Coma Scale. Future studies should assess the impact of practical experience and background on administration and scoring of the scale. © The Author(s) 2014.

Translation of the Spinal Cord Injury Falls Concern Scale (SCI-FCS), and investigation of test-retest reliability on item-level and total-score-level. Translation, adaptation and test-retest study. A specialized rehabilitation setting in Norway. Fifty-four wheelchair users with a spinal cord injury. The median age of the cohort was 49 years, and the median number of years after injury was 13. Interventions/measurements: The SCI-FCS was translated and back-translated according to guidelines. Individuals answered the SCI-FCS twice over the course of one week. We investigated item-level test-retest reliability using Svensson's rank-based statistical method for disagreement analysis of paired ordinal data. For relative reliability, we analyzed the total-score-level test-retest reliability with intraclass correlation coefficients (ICC2.1), the standard error of measurement (SEM), and the smallest detectable change (SDC) for absolute reliability/measurement-error assessment and Cronbach's alpha for internal consistency. All items showed satisfactory percentage agreement (≥69%) between test and retest. There were small but non-negligible systematic disagreements among three items; we recovered an 11-13% higher chance for a lower second score. There was no disagreement due to random variance. The test-retest agreement (ICC2.1) was excellent (0.83). The SEM was 2.6 (12%), and the SDC was 7.1 (32%). The Cronbach's alpha was high (0.88). The Norwegian SCI-FCS is highly reliable for wheelchair users with chronic spinal cord injuries.

The purpose of this study was to investigate whether the functional movement screen (FMS) could predict running injuries in competitive runners. Eighty-four competitive male runners (average age = 20.0 ± 1.1 years) participated. Each subject performed the FMS, which consisted of 7 movement tests (each score range: 0-3, total score range: 0-21), during the preseason. The incidence of running injuries (time lost because of injury ≤ 4 weeks) was investigated through a follow-up survey during the 6-month season. Mann-Whitney U-tests were used to investigate which movement tests were significantly associated with running injuries. The receiver-operator characteristic (ROC) analysis was used to determine the cutoff. The mean FMS composite score was 14.1 ± 2.3. The ROC analysis determined the cutoff at 14/15 (sensitivity = 0.73, specificity = 0.54), suggesting that the composite score had a low predictability for running injuries. However, the total scores (0-6) from the deep squat (DS) and active straight leg raise (ASLR) tests (DS and ASLR), which were significant with the U-test, had relatively high predictability at the cutoff of 3/4 (sensitivity = 0.73, specificity = 0.74). Furthermore, the multivariate logistic regression analysis revealed that the DS and ASLR scores of ≤3 significantly influenced the incidence of running injuries after adjusting for subjects' characteristics (odds ratio = 9.7, 95% confidence interval = 2.1-44.4). Thus, the current study identified the DS and ASLR score as a more effective method than the composite score to screen the risk of running injuries in competitive male runners.

Perception of the impact of voice disorders may differ across different cultural backgrounds. This study investigated the difference in the perception of the impact of voice disorders between the American (Pittsburgh) and Chinese (Hong Kong) cultures. Sixty dysphonic subjects from Hong Kong, China, and 60 dysphonic subjects from Pittsburgh, USA, were recruited to complete the Chinese and English versions of the Voice Activity and Participation Profile (VAPP), respectively. Data analyses using independent t tests were conducted on (1) the total profile scores; (b) total activity limitation score (ALS) and total participation restriction score (PRS); (c) section scores of job, daily communication, and social communication; and (d) section ALS and section PRS. Hong Kong subjects showed significantly higher scores than the Pittsburgh subjects in total profile and other subsections except in the job PRS. RESULTS support the possible influence of individualist and collectivist cultures on the perceived impact of voice disorders on the activity and participation. Copyright © 2011 The Voice Foundation.

To validate the Parsonnet scoring model to predict mortality following adult cardiac surgery in Indian scenario. A total of 889 consecutive patients undergoing adult cardiac surgery between January 2010 and April 2011 were included in the study. The Parsonnet score was determined for each patient and its predictive ability for in-hospital mortality was evaluated. The validation of Parsonnet score was performed for the total data and separately for the sub-groups coronary artery bypass grafting (CABG), valve surgery and combined procedures (CABG with valve surgery). The model calibration was performed using Hosmer-Lemeshow goodness of fit test and receiver operating characteristics (ROC) analysis for discrimination. Independent predictors of mortality were assessed from the variables used in the Parsonnet score by multivariate regression analysis. The overall mortality was 6.3% (56 patients), 7.1% (34 patients) for CABG, 4.3% (16 patients) for valve surgery and 16.2% (6 patients) for combined procedures. The Hosmer-Lemeshow statistic was <0.05 for the total data and also within the sub-groups suggesting that the predicted outcome using Parsonnet score did not match the observed outcome. The area under the ROC curve for the total data was 0.699 (95% confidence interval 0.62-0.77) and when tested separately, it was 0.73 (0.64-0.81) for CABG, 0.79 (0.63-0.92) for valve surgery (good discriminatory ability) and only 0.55 (0.26-0.83) for combined procedures. The independent predictors of mortality determined for the total data were low ejection fraction (odds ratio [OR] - 1.7), preoperative intra-aortic balloon pump (OR - 10.7), combined procedures (OR - 5.1), dialysis dependency (OR - 23.4), and re-operation (OR - 9.4). The Parsonnet score yielded a good predictive value for valve surgeries, moderate predictive value for the total data and for CABG and poor predictive value for combined procedures.

"Reliability of the Norwegian version of the short physical performance battery in older people with and without dementia".

Olsen, Cecilie Fromholt; Bergland, Astrid

2017-06-09

The purpose of the study was to establish the test-retest reliability of the Norwegian version of the Short Physical Performance Battery (SPPB). This was a cross- sectional reliability study. A convenience sample of 61 older adults with a mean age of 88.4(8.1) was tested by two different physiotherapists at two time points. The mean time interval between tests was 2.5 days. The Intraclass Correlation Coefficient model 3.1 (ICC, 3.1) with 95% confidence intervals as well as the weighted Kappa (K) were used as measures of relative reliability. The Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) were used to measure absolute reliability. The results were also analyzed for a subgroup of 24 older people with dementia. The ICC reflected high relative reliability for the SPPB summary score and the 4 m walk test (4mwt), both for the total sample (ICC = 0.92, and 0.91 respectively)) and for the subgroup with dementia (ICC = 0.84 and 0.90 respectively). Furthermore, weighted Ks for the SPPB subscales were 0.64 for the chair stand, 0.80 for gait and 0.52 for balance for the total sample and almost identical for the subgroup with dementia. MDC-values at the 95% confidence intervals (MDC95) were calculated at 0.8 for the total score of SPPB and 0.39 m/s for the 4mwt in the total sample. For the subgroup with dementia MDC95 was 1.88 for the total score of SPPB and 0.28 m/s for 4mwt. The SPPB total score and the timed walking test showed overall high relative and absolute reliability for the total sample indicating that the Norwegian version of the SPPB is reliable when used by trained physiotherapists with older people. The reliability of the Norwegian SPPB in older people with dementia seems high, but due to a small sample size this needs further investigation.

To date, there is no overall consensus on the definition of cure after surgery for pelvic organ prolapse (POP). The aim of the study was to design and test the scoring system S.A.C.S. (Satisfaction-Anatomy-Continence-Safety) to assess and compare the outcomes of POP repair. A total of 233 women underwent open sacrocolpopexy. The S.A.C.S. outcome scoring system was scheduled at 24 months of follow-up, and each component was detected according to: Satisfaction by mean of Patient Global Improvement Inventory scale, Anatomy by mean of POP Quantification system and bulge symptom, Continence by mean of pad use, and Safety by mean of the Clavien-Dindo classification of surgical complications. Each component produced a binary nominal categorical variable (1 or 0), with a total score of 4 representing cure. As a comparative tool, patients answered a simple yes/no question: "If you had to undergo surgery all over again, would you still do it?". The degree of concordance was estimated using Cohen's Kappa test. According to the S.A.C.S. scoring system, only 160 patients (68.6 %) reached the maximum score of cure. Sensitivity of the S.A.C.S. score was 74.1 %, specificity was 90 %, total diagnostic capacity was 75.5 %. The S.A.C.S. score internal consistency was good; the k-coefficient was higher for the satisfaction component of the score (k = 0.560). This study proposes an original, simple post-operative scoring system integrating satisfaction, anatomy, continence, and safety reports for patients undergoing surgery for POP, providing a complete, although perfectible, method to accurately report outcomes in all clinical scenarios.

Background The KIPPPI (Brief Instrument Psychological and Pedagogical Problem Inventory) is a Dutch questionnaire that measures psychosocial and pedagogical problems in 2-year olds and consists of a KIPPPI Total score, Wellbeing scale, Competence scale, and Autonomy scale. This study examined the reliability, validity, screening accuracy and clinical application of the KIPPPI. Methods Parents of 5959 2-year-old children in the Rotterdam area, the Netherlands, were invited to participate in the study. Parents of 3164 children (53.1% of all invited parents) completed the questionnaire. The internal consistency was evaluated and in subsamples the test-retest reliability and concurrent validity with regard to the Child Behavioral Checklist (CBCL). Discriminative validity was evaluated by comparing scores of parents who worried about their child’s upbringing and parent’s that did not. Screening accuracy of the KIPPPI was evaluated against the CBCL by calculating the Receiver Operating Characteristic (ROC) curves. The clinical application was evaluated by the relation between KIPPPI scores and the clinical decision made by the child health professionals. Results Psychometric properties of the KIPPPI Total score, Wellbeing scale, Competence scale and Autonomy scale were respectively: Cronbach’s alphas: 0.88, 0.86, 0.83, 0.58. Test-retest correlations: 0.80, 0.76, 0.73, 0.60. Concurrent validity was as hypothesised. The KIPPPI was able to discriminate between parents that worried about their child and parents that did not. Screening accuracy was high (>0.90) for the KIPPPI Total score and for the Wellbeing scale. The KIPPPI scale scores and clinical decision of the child health professional were related (p<0.05), indicating a good clinical application. Conclusion The results in this large-scale study of a diverse general population sample support the reliability, validity and clinical application of the KIPPPI Total score, Wellbeing scale and Competence scale. Also, the screening accuracy of the KIPPPI Total score and Wellbeing scale were supported. The Autonomy scale needs further study. PMID:23185388

To describe the development and initial testing of the Pieper-Zulkowski Pressure Ulcer Knowledge Test (PZ-PUKT). Cross-sectional, instrument testing. Hospital association pressure ulcer educational program conference. Pressure ulcer research and guidelines from the last 5 years were examined for test item content. The initial PZ-PUKT had 115 items; response options were "true," "false," and "don't know." Registered nurses (N = 108) were randomly divided into 2 groups to take either the 60 prevention/risk and staging items or the 55 wound description items. Analyses of these responses resulted in 72 items, which were administered in total to a second cohort of 98 nurses for reliability. Cronbach's α was .80 for the 72-item PZ-PUKT. Cronbach's α values for the subscales were as follows: staging, .67; wound description, .64; and prevention/risk, .56. The mean correct scores were as follows: total, 80%; prevention, 77%; staging, 86%; and wound description, 77%. Nurses with wound care certification scored significantly higher on the PZ-PUKT than did nurses with other clinical certifications or with nurses who lacked certification. The PZ-PUKT has updated content about pressure ulcer prevention/risk, staging, and wound description. Reliability values are highest for the total test. Further use of the instrument in diverse settings will add to reliability testing and may provide direction for determination of a passing cutoff score.

The aim of this study is to assess the comprehensibility, internal consistency, patient-physician reliability, test-retest reliability, and validity of Turkish version of Migraine Disability Assessment (MIDAS) questionnaire in patients with headache. MIDAS questionnaire has been developed by Stewart et al and shown to be reliable and valid to determine the degree of disability caused by migraine. This study was designed as a national multicenter study to demonstrate the reliability and validity of Turkish version of MIDAS questionnaire. Patients applying to 17 Neurology Clinics in Turkey were evaluated at the baseline (visit 1), week 4 (visit 2), and week 12 (visit 3) visits in terms of disease severity and comprehensibility, internal consistency, test-retest reliability, and validity of MIDAS. Since the severity of the disease has been found to change significantly at visit 2 compared to visit 1, test-retest reliability was assessed using the MIDAS scores of a subgroup of patients whose disease severity remained unchanged (up to +/-3 days difference in the number of days with headache between visits 1 and 2). A total of 306 patients (86.2% female, mean age: 35.0 +/- 9.8 years) were enrolled into the study. A total of 65.7%, 77.5%, 82.0% of patients reported that "they had fully understood the MIDAS questionnaire" in visits 1, 2, and 3, respectively. A highly positive correlation was found between physician and patient and the applied total MIDAS scores in all three visits (Spearman correlation coefficients were R= 0.87, 0.83, and 0.90, respectively, P <.001). Internal consistency of MIDAS was assessed using Cronbach's alpha and was found at acceptable (>0.7) or excellent (>0.8) levels in both patient and physician applied MIDAS scores, respectively. Total MIDAS score showed good test-retest reliability (R= 0.68). Both the number of days with headache and the total MIDAS scores were positively correlated at all visits with correlation coefficients between 0.47 and 0.63. There was also a moderate degree of correlation (R= 0.54) between the total MIDAS score at week 12 and the number of days with headache at visit 2 + visit 3, which quantify headache-related disability over a 3-month period similar to MIDAS questionnaire. These findings demonstrated that the Turkish translation is equivalent to the English version of MIDAS in terms of internal consistency, test-retest reliability, and validity. Physicians can reliably use the Turkish translation of the MIDAS questionnaire in defining the severity of illness and its treatment strategy when applied as a self-administered report by migraine patients themselves.

Introduction The aim of this study was to compare schizophrenic patients with and without a suicide attempt history in terms of sociodemographic and clinical features and cognitive functions and to determine the predictive factors for suicide attempt history. Methods In this study, we assessed and compared 70 patients with schizophrenia, 27 patients with a suicide attempt history, and 43 patients without a suicide attempt history. The cognitive functions of patients were assessed by the Stroop test, Wisconsin Card Sorting Test (WCST), and Rey Auditory Verbal Learning Test. In order to evaluate clinical symptoms, the Positive and Negative Syndrome Scale (PANSS) and Calgary Depression Scale for Schizophrenia (CDSS) were used. Results In this study, the number of hospitalizations, PANSS general psychopathology subscale score, CDSS total score, suicide item score, and WCST total number of responses (WCST1) were significantly higher among the patients with a suicide attempt history. The WCST1 and CDSS total scores were predicted using the suicide attempt history. Conclusion Revealing the factors related to suicidal behavior in patients with schizophrenia contributes to the prevention of suicide. Studies with long-term follow-up and with a larger sample group are required for the investigation of relationship suicide, cognitive impairment, which is one of the core symptoms of schizophrenia, and depression.

Clinical reasoning is one of the most important skills in the process of training a medical student to become an efficient physician. Assessment of the reasoning skills in a medical school program is important to direct students' learning. One of the tests for measuring the clinical reasoning ability is Clinical Reasoning Problems (CRPs). The major aim of this study is to measure psychometric qualities of CRPs and define correlation between this test and routine MCQ in cardiology department of Shiraz medical school. This study was a descriptive study conducted on total cardiology residents of Shiraz Medical School. The study population consists of 40 residents in 2014. The routine CRPs and the MCQ tests was designed based on similar objectives and were carried out simultaneously. Reliability, item difficulty, item discrimination, and correlation between each item and the total score of CRPs were all measured by Excel and SPSS software for checking psycometeric CRPs test. Furthermore, we calculated the correlation between CRPs test and MCQ test. The mean differences of CRPs test score between residents' academic year [second, third and fourth year] were also evaluated by Analysis of variances test (One Way ANOVA) using SPSS software (version 20)(α=0.05). The mean and standard deviation of score in CRPs was 10.19 ±3.39 out of 20; in MCQ, it was 13.15±3.81 out of 20. Item difficulty was in the range of 0.27-0.72; item discrimination was 0.30-0.75 with question No.3 being the exception (that was 0.24). The correlation between each item and the total score of CRP was 0.26-0.87; the correlation between CRPs test and MCQ test was 0.68 (p<0.001). The reliability of the CRPs was 0.72 as calculated by using Cronbach's alpha. The mean score of CRPs was different among residents based on their academic year and this difference was statistically significant (p<0.001). The results of this present investigation revealed that CRPs could be reliable test for measuring clinical reasoning in residents. It can be included in cardiology residency assessment programs.

To determine whether performance in any of the Health Professions Admissions Test (HPAT) sections, most specifically the interpersonal understanding section, correlates with self-reported empathy levels in medical students. The study was conducted in University College Cork, Ireland. 290 students participated in the study. Matching HPAT scores were available for 263 students. All male and female undergraduate students were invited to participate. Postgraduate and international students were excluded. Primary measures: HPAT-Ireland and Jefferson Scale of Physician Empathy (JSE) scores were compared including subsection analysis. Secondary measures: comparisons were made between groups such as gender and year of programme. A total of 290 students participated. Males scored significantly higher than females for total HPAT-Ireland (U=7329, z=-2.04, p<0.05), HPAT-Ireland section 1 (U=5382, z=-5.21, p<0.001) and section 3 scores (U=6833, z=-2.85, p<0.01). In contrast, females scored significantly higher than males on HPAT-Ireland section 2 (U=5844, z=-4.46, p<0.001). Females demonstrated significantly higher total JSE scores relative to males (mean score ± SEM: 113.33±1.05 vs 109.21±0.95; U=8450, z=-2.83, p<0.01). No significant association was observed between JSE scores and any of the HPAT-Ireland measures (all p>0.05). There was no effect of programme year on JSE scores (all p>0.05). The introduction of the HPAT-Ireland test was partly designed to identify students with strong interpersonal skills. A significant finding of this study is that JSE values did not correlate with HPAT-Ireland scores. This study suggests no clear link between scores on a selection test, the HPAT-Ireland, which is designed to assess several skill domains including interpersonal skills, and scores on a psychometric measure of empathy, at any point during medical education. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The Fundamentals of Endoscopic Surgery™ (FES) program consists of online materials and didactic and skills-based tests. All components were designed to measure the skills and knowledge required to perform safe flexible endoscopy. The purpose of this multicenter study was to evaluate the reliability and validity of the hands-on component of the FES examination, and to establish the pass score. Expert endoscopists identified the critical skill set required for flexible endoscopy. They were then modeled in a virtual reality simulator (GI Mentor™ II, Simbionix™ Ltd., Airport City, Israel) to create five tasks and metrics. Scores were designed to measure both speed and precision. Validity evidence was assessed by correlating performance with self-reported endoscopic experience (surgeons and gastroenterologists [GIs]). Internal consistency of each test task was assessed using Cronbach's alpha. Test-retest reliability was determined by having the same participant perform the test a second time and comparing their scores. Passing scores were determined by a contrasting groups methodology and use of receiver operating characteristic curves. A total of 160 participants (17 % GIs) performed the simulator test. Scores on the five tasks showed good internal consistency reliability and all had significant correlations with endoscopic experience. Total FES scores correlated 0.73, with participants' level of endoscopic experience providing evidence of their validity, and their internal consistency reliability (Cronbach's alpha) was 0.82. Test-retest reliability was assessed in 11 participants, and the intraclass correlation was 0.85. The passing score was determined and is estimated to have a sensitivity (true positive rate) of 0.81 and a 1-specificity (false positive rate) of 0.21. The FES hands-on skills test examines the basic procedural components required to perform safe flexible endoscopy. It meets rigorous standards of reliability and validity required for high-stakes examinations, and, together with the knowledge component, may help contribute to the definition and determination of competence in endoscopy.

This study examined the reliability and validity of the Japanese versions of the DISABKIDS-37 generic modules, a tool for assessing the health-related quality of life (HRQOL) of children and adolescents with a chronic condition. The study was conducted using a sample of 123 children/adolescents with a chronic medical condition, aged 8-18 years, and their parents. Focus interviews were performed to ensure content validity after translation. The classical psychometric tests were used to assess reliability and scale intercorrelations. The factor structure was examined with confirmatory factor analysis (CFA). Convergent validity was assessed by the correlation between the total score and the sub-scales of DISABKIDS-37 as well as the total score of KIDSCREEN-10. Both the children/adolescent and parent versions of the score showed good to high internal consistency, and the test-retest reliability correlations were r = 0.91 or above. The CFA revealed that the modified models for all domains were better fit than the original 37 item scale model for both self-report and proxy-report. Moderate to high positive correlations were found for the associations within DISABKIDS-37 sub-scales and between the subscales and total score, except for the treatment sub-scale, which correlated weakly with the remaining sub-scales. The total score of the child-reported version of KIDSCREEN-10 correlated significantly and positively with the total score and all the sub-scales of the child-reported version of DISABKIDS-37 except the Treatment sub-scale in adolescents. The modified models of Japanese version of DISABKIDS generic module were psychometrically robust enough to assess the HRQOL of children with a chronic condition.

The Italian translations of the Pathological Narcissism Inventory (PNI) and Triarchic Psychopathy Measure (TriPM) were administered to 609 community dwelling adults. Participants who scored in the upper 10% of the distribution of the PNI total score were assigned to the group of participants at risk for pathological narcissism, whereas participants who scored in the upper 10% of the distribution of the TriPM total score were assigned to the group of participants at risk for psychopathy. The final sample included 126 participants who were administered the Reading the Mind in the Eyes Test (RMET) and emotion-eliciting movie clips. Participants at risk for pathological narcissism scored significantly lower on the RMET total score than participants who were not at risk for pathological narcissism. Participants at risk for psychopathy showed a significant reduction in the subjective experience of disgust, fear, sadness, and tenderness compared to participants who were not at risk for psychopathy.

The number-transcoding task on the Japanese version of the Rapid Dementia Screening Test (RDST-J) requires mutual conversion between Arabic and Chinese numerals (209 to , 4054 to , to 681, to 2027). In this task, question and answer styles of Chinese numerals are written horizontally. We investigated the impact of changing the task so that Chinese numerals are written vertically. Subjects were 211 patients with very mild to severe Alzheimer's disease and 42 normal controls. Mini-Mental State Examination scores ranged from 26 to 12, and Clinical Dementia Rating scores ranged from 0.5 to 3. Scores of all four subtasks of the transcoding task significantly improved in the revised version compared with the original version. The sensitivity and specificity of total scores ≥9 on the RDST-J original and revised versions for discriminating between controls and subjects with Clinical Dementia Rating scores of 0.5 were 63.8% and 76.6% on the original and 60.1% and 85.8% on revised version. The revised RDST-J total score had low sensitivity and high specificity compared with the original RDST-J for discriminating subjects with Clinical Dementia Rating scores of 0.5 from controls. © 2017 Japanese Psychogeriatric Society.

Patient-reported questionnaires in MS rehabilitation: responsiveness and minimal important difference of the multiple sclerosis questionnaire for physiotherapists (MSQPT).

2017-03-16

The Multiple Sclerosis Questionnaire for Physical Therapists (MSQPT) is a patient-rated outcome questionnaire for evaluating the rehabilitation of persons with multiple sclerosis (MS). Responsiveness was evaluated, and minimal important difference (MID) estimates were calculated to provide thresholds for clinical change for four items, three sections and the total score of the MSQPT. This multicentre study used a combined distribution- and anchor-based approach with multiple anchors and multiple rating of change questions. Responsiveness was evaluated using effect size, standardized response mean (SRM), modified SRM and relative efficiency. For distribution-based MID estimates, 0.2 and 0.33 standard deviations (SD), standard error of measurement (SEM) and minimal detectable change were used . Triangulation of anchor- and distribution-based MID estimates provided a range of MID values for each of the four items, the three sections and the total score of the MSQPT. The MID values were tested for their sensitivity and specificity for amelioration and deterioration for each of the four items, the three sections and the total score of the MSQPT. The MID values of each item and section and of the total score with the best sensitivity and specificity were selected as thresholds for clinical change. The outcome measures were the MSQPT, Hamburg Quality of Life Questionnaire for Multiple Sclerosis (HAQUAMS), rating of change questionnaires, Expanded Disability Status Scale, 6-metre timed walking test, Berg Balance Scale and 6-minute walking test. The effect size ranged from 0.46 to 1.49. The SRM data showed comparable results. The modified SRM ranged from 0.00 to 0.60. Anchor-based MID estimates were very low and were comparable with SD- and SEM-based estimates. The MSQPT was more responsive than the HAQUAMS in detecting improvement but less responsive in finding deterioration. The best MID estimates of the items, sections and total score, expressed in percentage of their maximum score, were between 5.4% (activity) and 22% (item 10) change for improvement and between 5.7% (total score) and 22% (item 10) change for deterioration. The MSQPT is a responsive questionnaire with an adequate MID that may be used as threshold for change during rehabilitation of MS patients. This trial was retrospectively (01/24/2015) registered in ClinicalTrials.gov as NCT02346279.

Correlation between musical responsiveness and developmental age among early age children as assessed by the Non-Verbal Measurement of the Musical Responsiveness of Children.

The currently-available standardized music tests are not suitable for administration to young children and children with special needs because they are complicated and require verbal instructions and verbal responses. A test that was named the Non-Verbal Measurement of the Musical Responsiveness of Children, was developed to assess the musical responsiveness of young children. This test does not depend on verbal instructions, and is composed of two parts, Rhythm and Melody. Ninety-two children [age, range, 6-69 months; 36.39+/-17.61 (mean +/-standard deviation) months] who attended mainstream pre-schools were studied. Each child was tested to see whether the child correctly imitated 7 different patterns of rhythm and 6 different patterns of melody that were delivered by clapping of hands or the voice of the examiner, respectively. The examiner rated whether the child could imitate each pattern and the total score was the sum of successfully reproduced patterns. Two independent observers viewed videotapes of the testing sessions and assigned scores in a similar manner. The inter-rater reliability among the three raters was assessed. The total score in Melody (R=0.63, p<0.001) and the total score in Rhythm (R=0.81, p<0.001) were each correlated with developmental age. The inter-rater reliability was good (Melody: Kendall's W=0.78, Rhythm: Kendall's W=0.95). The degree of musical responsiveness of normal young children is correlated with general development. This measurement tool is valid and reliable for use in young children who lack sufficient verbal understanding to take standardized music tests. This test may also be administered to children with special needs.

Item Selection and Pre-equating with Empirical Item Characteristic Curves.

Livingston, Samuel A.

An empirical item characteristic curve shows the probability of a correct response as a function of the student's total test score. These curves can be estimated from large-scale pretest data. They enable test developers to select items that discriminate well in the score region where decisions are made. A similar set of curves can be used to…

Little is known about the critical on-road driving skills that get affected after a stroke. The purpose of this study was to investigate the key on-road driving impairments and their associated cognitive deficits after a stroke. A second aim was to investigate if lateralization of stroke impacts results of the cognitive and on-road driving tests. In this cross-sectional study, 99 participants with a first-ever stroke who were actively driving prior to stroke underwent a cognitive battery and a standardized road test that evaluated 13 specific on-road driving skills. These on-road driving skills were mapped onto an existing, theoretical framework that categorized the on-road items into hierarchic clusters of operational, tactical, visuo-integrative, and mixed driving skills. The total score on the road test and the on-road decision, made by a certified fitness-to-drive expert, decided the main outcome. The critical on-road driving skills predicting the on-road decision were identified using logistic regression analysis. Linear regression analysis was employed to determine the cognitive impairments leading to poor total on-road scores. Analyses were repeated for right- and left-sided strokes. In all, 37 persons scored poorly on the road test. These participants performed worse in all hierarchic clusters of on-road driving. Performances on the operational cluster and the visuo-integrative cluster best predicted on-road decisions (R(2) = 0.60). 'Lane changing' and 'understanding, insight, and quality of traffic participation' were the critical skill deficits leading to poor performance on the road test (R(2) = 0.65). Divided attention was the main determinant of on-road scores in the total group (R(2) = 0.06). Participants with right-sided stroke performed worse on visual field, visual neglect, visual scanning, visuo-constructive skills, and divided attention compared with those with left-sided stroke. Divided attention was the main determinant of total on-road scores in the right-sided stroke group (R(2) = 0.10). A combination of visual scanning, speed of processing, and executive dysfunction yielded the best model to predict on-road scores in left-sided strokes (R(2) = 0.46). Poor performance in the road test after stroke is determined by critical operational and visuo-integrative driving impairments. Specific and different driving evaluation and training programs are needed for right- and left-sided strokes. © 2014 S. Karger AG, Basel.

The Free and Cued Selective Reminding test (FCSRT) was used to assess memory in 19 patients with prodromal dementia with Lewy bodies (DLB) and 25 Alzheimer's disease (AD) patients. DLB scored better than AD in selective measures of the FCSRT: immediate total recall (p = 0.01) and index of sensitivity of cueing (p = 0.001), while free delayed and total memory scores were similarly impaired. The index of sensitivity of cueing held a sensitivity of 76% and specificity of 79% in distinguishing DLB. FCSRT could help in disentangling hippocampal memory deficits from memory impairment due to ineffective recall strategies.

Tobii eye tracking was compared with webcam-based observer scoring on an animation viewing measure of attention (Early Childhood Vigilance Test; ECVT) to evaluate the feasibility of automating measurement and scoring. Outcomes from both scoring approaches were compared with the Mullen Scales of Early Learning (MSEL), Color-Object Association Test (COAT), and Behavior Rating Inventory of Executive Function for preschool children (BRIEF-P). A total of 44 children 44 to 65 months of age were evaluated with the ECVT, COAT, MSEL, and BRIEF-P. Tobii ×2-30 portable infrared cameras were programmed to monitor pupil direction during the ECVT 6-min animation and compared with observer-based PROCODER webcam scoring. Children watched 78% of the cartoon (Tobii) compared with 67% (webcam scoring), although the 2 measures were highly correlated (r = .90, p = .001). It is possible for 2 such measures to be highly correlated even if one is consistently higher than the other (Bergemann et al., 2012). Both ECVT Tobii and webcam ECVT measures significantly correlated with COAT immediate recall (r = .37, p = .02 vs. r = .38, p = .01, respectively) and total recall (r = .33, p = .06 vs. r = .42, p = .005) measures. However, neither the Tobii eye tracking nor PROCODER webcam ECVT measures of attention correlated with MSEL composite cognitive performance or BRIEF-P global executive composite. ECVT scoring using Tobii eye tracking is feasible with at-risk very young African children and consistent with webcam-based scoring approaches in their correspondence to one another and other neurocognitive performance-based measures. By automating measurement and scoring, eye tracking technologies can improve the efficiency and help better standardize ECVT testing of attention in younger children. This holds promise for other neurodevelopmental tests where eye movements, tracking, and gaze length can provide important behavioral markers of neuropsychological and neurodevelopmental processes associated with such tests.

We previously operationally-defined subtle cognitive decline (SCD) in preclinical Alzheimer's disease (AD) using total scores on neuropsychological (NP) tests. NP process scores (i.e., provide information about how a total NP score was achieved) may be a useful tool for identifying early cognitive inefficiencies prior to objective impairment seen in mild cognitive impairment (MCI) and dementia. We aimed to integrate process scores into the SCD definition to identify stages of SCD and improve early detection of those at risk for decline. Cognitively "normal" participants from the Alzheimer's Disease Neuroimaging Initiative were classified as "early" SCD (E-SCD; >1 SD below mean on 2 process scores or on 1 process score plus 1 NP total score), "late" SCD (L-SCD; existing SCD criteria of >1 SD below norm-adjusted mean on 2 NP total scores in different domains), or "no SCD" (NC). Process scores considered in the SCD criteria were word-list intrusion errors, retroactive interference, and learning slope. Cerebrospinal fluid AD biomarkers were used to examine pathologic burden across groups. E-SCD and L-SCD progressed to MCI 2.5-3.4 times faster than the NC group. Survival curves for E-SCD and L-SCD converged at 7-8 years after baseline. The combined (E-SCD+L-SCD) group had improved sensitivity to detect progression to MCI relative to L-SCD only. AD biomarker positivity increased across NC, SCD, and MCI groups. Process scores can be integrated into the SCD criteria to allow for increased sensitivity and earlier identification of cognitively normal older adults at risk for decline prior to frank impairment on NP total scores.

The quantitative LOD score: test statistic and sample size for exclusion and linkage of quantitative traits in human sibships.

1998-04-01

We present a test statistic, the quantitative LOD (QLOD) score, for the testing of both linkage and exclusion of quantitative-trait loci in randomly selected human sibships. As with the traditional LOD score, the boundary values of 3, for linkage, and -2, for exclusion, can be used for the QLOD score. We investigated the sample sizes required for inferring exclusion and linkage, for various combinations of linked genetic variance, total heritability, recombination distance, and sibship size, using fixed-size sampling. The sample sizes required for both linkage and exclusion were not qualitatively different and depended on the percentage of variance being linked or excluded and on the total genetic variance. Information regarding linkage and exclusion in sibships larger than size 2 increased as approximately all possible pairs n(n-1)/2 up to sibships of size 6. Increasing the recombination (theta) distance between the marker and the trait loci reduced empirically the power for both linkage and exclusion, as a function of approximately (1-2theta)4.

The purpose of this study was to reduce the number of items in the Modified Finnegan Neonatal Abstinence Syndrome Tool (M-FNAST) to the minimum possible while retaining or improving its validity in a short version. All infants with a diagnosis of neonatal abstinence syndrome (171) who were admitted to a large neonatal intensive care unit in southwest Florida between September 2010 and October 2012 comprised the sample. This was a psychometric evaluation of 33 856 M-FNAST assessments that were downloaded from the electronic medical record. Principal axis factoring extraction with varimax rotation was performed on the M-FNAST data. Principal components extraction was used before principal factors extraction to estimate the number of factors with the scree test and factorability of the correlation matrices with Bartlett's chi-square test, and Kaiser-Meyer-Olkin Measure of Sampling Adequacy. The M-FNAST scores ranged from 0 to 29, with a mean of 3.5 (SD = 2.5). Less than 1% (21) of infants had scores of 17 or more. Nearly all (97.7%) scores fell between 0 and 9. Most subjects were full-term gestation, but 11 were preterm between 28 and 37 weeks' gestational age. The 2-factor solution explained 23.74% of the total variance and consists of 2 factors, mild/early and moderate/advanced signs. The 2-factor solution was significantly correlated with the total score on the MFNAST (r = 0.917; P < .001). Among infants who scored 8 or greater, the total score on the 2-factor solution short form FNAST was significantly correlated with the total score on the M-FNAST (r = 0.629; P < .001).

Pain catastrophizing has been found to be an important predictor of disability and days lost from work in patients with low back pain. The most commonly used outcome measure to identify pain catastrophizing is the Pain Catastrophizing Scale (PCS). To enable the use of the PCS in clinical settings and research in Norwegian speaking patients, the PCS had to be translated. The purpose of this study was therefore to translate and cross-culturally adapt the PCS into Norwegian and to test internal consistency, construct validity and reproducibility of the PCS. The PCS was translated before it was tested for psychometric properties. Patients with subacute or chronic non-specific low back pain aged 18 years or more were recruited from primary and secondary care. Validity of the PCS was assessed by evaluating data quality (missing, floor and ceiling effects), principal components analysis, internal consistency (Cronbach's alpha), and construct validity (Spearman's rho). Reproducibility analyses included standard error of measurement, minimum detectable change, limits of agreement, and intraclass correlation coefficients. A total of 38 men and 52 women (n = 90), with a mean (SD) age of 47.6 (11.7) years, were included for baseline testing. A subgroup of 61 patients was included for test-retest assessments. The Norwegian PCS was easy-to-comprehend. The principal components analysis supported a three-factor structure, internal consistency was satisfactory for the PCS total score (α 0.90) and the subscales rumination (α 0.83) and helplessness (α 0.86), but not for the subscale magnification (α 0.53). In total, 86% of the correlation analyses were in accordance with predefined hypothesis. The reliability analyses showed intraclass correlation coefficients of 0.74 - 0.87 for the PCS total score and subscales. The PCS total score (range 0-52 points) showed a standard error of measurement of 4.6 points and a 95% minimum detectable change estimate of 12.8 points. The Norwegian PCS total score showed acceptable psychometric properties in terms of comprehensibility, consistency, construct validity, and reproducibility when applied to patients with subacute or chronic LBP from different clinical settings. Our study support the use of the PCS total score for clinical or research purposes identifying or evaluating pain catastrophizing.

Nonadherence produces considerable health consequences and economic burden to patients and payers. One approach to improve medication nonadherence that has gained interest in recent years is the use of smartphone adherence apps. The development of smartphone adherence apps has increased rapidly since 2012; however, literature evaluating the clinical app and effectiveness of smartphone adherence apps to improve medication adherence is generally lacking. The aims of this study were to (1) provide an updated evaluation and comparison of medication adherence apps in the marketplace by assessing the features, functionality, and health literacy (HL) of the highest-ranking adherence apps and (2) indirectly measure the validity of our rating methodology by determining the relationship between our app evaluations and Web-based consumer ratings. Two independent reviewers assessed the features and functionality using a 4-domain rating tool of all adherence apps identified based on developer claims. The same reviewers downloaded and tested the 100 highest-ranking apps including an additional domain for assessment of HL. Pearson product correlations were estimated between the consumer ratings and our domain and total scores. A total of 824 adherence apps were identified; of these, 645 unique apps were evaluated after applying exclusion criteria. The median initial score based on descriptions was 14 (max of 68; range 0-60). As a result, 100 of the highest-scoring unique apps underwent user testing. The median overall user-tested score was 31.5 (max of 73; range 0-60). The majority of the user tested the adherence apps that underwent user testing reported a consumer rating score in their respective online marketplace. The mean consumer rating was 3.93 (SD 0.84). The total user-tested score was positively correlated with consumer ratings (r=.1969, P=.04). More adherence apps are available in the Web-based marketplace, and the quality of these apps varies considerably. Consumer ratings are positively but weakly correlated with user-testing scores suggesting that our rating tool has some validity but that consumers and clinicians may assess adherence app quality differently. ©Lindsey E Dayer, Rebecca Shilling, Madalyn Van Valkenburg, Bradley C Martin, Paul O Gubbins, Kristie Hadden, Seth Heldenbrand.

Cognitive impairment affects approximately 50% of people with amyotrophic lateral sclerosis (ALS). Research has indicated that impairment may worsen with disease progression. The Edinburgh Cognitive and Behavioural ALS Screen (ECAS) was designed to measure neuropsychological functioning in ALS, with its alternate forms (ECAS-A, B, and C) allowing for serial assessment over time. The aim of the present study was to establish reliable change scores for the alternate forms of the ECAS, and to explore practice effects and test-retest reliability of the ECAS's alternate forms. Eighty healthy participants were recruited, with 57 completing two and 51 completing three assessments. Participants were administered alternate versions of the ECAS serially (A-B-C) at four-month intervals. Intra-class correlation analysis was employed to explore test-retest reliability, while analysis of variance was used to examine the presence of practice effects. Reliable change indices (RCI) and regression-based methods were utilized to establish change scores for the ECAS alternate forms. Test-retest reliability was excellent for ALS Specific, ALS Non-Specific, and ECAS Total scores of the combined ECAS A, B, and C (all > .90). No significant practice effects were observed over the three testing sessions. RCI and regression-based methods produced similar change scores. The alternate forms of the ECAS possess excellent test-retest reliability in a healthy control sample, with no significant practice effects. The use of conservative RCI scores is recommended. Therefore, a change of ≥8, ≥4, and ≥9 for ALS Specific, ALS Non-Specific, and ECAS Total score is required for reliable change.

A total of 199 patients were selected for a comparison of the anti-dandruff efficacy of four shampoos. After a 2-week lead in (all patients used only Johnson's Baby Shampoo twice weekly) the patients were randomly assigned to Selsun Blue, Head & Shoulders, Flex, or Tegrin. The test preparation, which was unknown to the observer, was used twice weekly for 4 weeks. Loose and adherent dandruff were each rated on a scale of 0 to 20 (absent to severe) at the end of the lead-in (when a total score of 15 was required), and each week of study. The mean total pre-study score for all subjects was 19.5. At the end of the study the mean improvement scores were: 16.2 (Selsun Blue), 14.6 (head & Shoulders), 13.5 (Flex), and 13.1 (Tegrin). The improvement was significantly greater (p less than 0.05) on Selsun Blue than on any of the other shampoo. At the end of the study significantly (p less than 0.05) more patients had total scores of zero on Selsun Blue (15) than on Tegrin or Head & Shoulders. In addition, the rate of improvement was significantly (p less than 0.05) faster with Selsun Blue than with any of the other test preparations.

Postoperative pain control is a significant concern after total shoulder arthroplasty. Injectable periarticular liposomal bupivacaine, which has been found to decrease opioid use after orthopedic procedures, has been proposed as a viable alternative to regional anesthesia. This study compared the efficacy of liposomal bupivacaine vs interscalene block among patients undergoing total shoulder arthroplasty. A retrospective review was conducted of 79 patients who underwent anatomic total shoulder arthroplasty performed by a single surgeon between January 2013 and April 2015. Patient demographics, in-hospital Numeric Pain Rating Scale (NPRS) score obtained at 12-hour intervals, length of stay, and total in-hospital morphine equivalents in both the bupivacaine (n=25) and block (n=44) groups were recorded. Differences in length of stay, morphine equivalents, and age were assessed with Wilcoxon tests. Sex differences were assessed with the chi-square test. Repeated measures analysis with least square means was used to assess longitudinal changes in NPRS scores. No significant differences were found between groups for sex (P=.89), age (P=.81), American Society of Anesthesiologists classification (P=.50), preoperative opioid use (P=.41), length of stay (P=.32), or morphine equivalents (P=.71). The average NPRS score in the first 12 hours was 3.01 for the bupivacaine group and 4.41 for the interscalene block group (P=.25). By 48 hours postoperatively, average NPRS scores were similar (P=.93) for the 2 groups, 4.90 for the bupivacaine group and 4.19 for the interscalene block group. The findings for this cohort of patients undergoing anatomic total shoulder arthroplasty showed no significant difference for pain scores, postoperative narcotic use, or length of stay with injectable liposomal bupivacaine vs interscalene block.

Objective: Development of early social skills in children is a complex process. To understand this process, it is important to assess how strengths or weaknesses in other developmental domains may be affected by these skills. The present study aimed at investigating the association of motor skills and imitation ability with early social communication skills in children with autism spectrum disorder (ASD). Method: In this study, 20 children with ASD aged 3 to 5 years (M = 4.05, SD = 0.55) participated. All children were diagnosed as ASD based on the DSM-V criteria by an independent child psychiatrist. Additionally, Autism Diagnostic interview-Revised was used for subsequent diagnostic confirmation. Children were tested with Test of Gross Motor Development (TGMD-2), the Motor Imitation Scale (MIS), and the Early Social Communication Scales (ESCS). All examinations were videotaped for subsequent scoring. The relationship between these skills was estimated by Pearson correlation coefficient. Results: A significant and strong correlation was obtained between TGMD total score and imitation total score (r =.776; p <0.001). However, the relationship between MIS subscales and TGMD-2 locomotor subtest scores was not significant (P>0.05). A significant correlation was found between MIS and TGMD total scores with Initiating Joint Attention and Responding to Joint Attention (p≤0/025) as ESCS subscales. But MIS and TGMD total scores were not correlated with social interaction and responding to behavioral requests subscales. Conclusion: The results of the present study showed that indicated both imitation ability and motor function have an association with each other and with early social communication skills.

Therapeutic options for patients failing hepatitis C retreatment are limited. EPIC(3) included a prospective trial assessing long-term peginterferon alfa-2b (PegIFNα-2b) maintenance therapy in patients with METAVIR fibrosis scores (MFS) of F2 or F3 who previously failed hepatitis C retreatment. Patients with F2/F3 MFS who failed retreatment were randomized to PegIFNα-2b (0.5 μg/kg/week, n=270) or observation (n=270) for 36 months. Blinded liver biopsies obtained before retreatment and after maintenance therapy were evaluated using MFS and activity scores, and confirmatory testing was performed using FibroTest and ActiTest. In total, 348 patients had paired biopsies: 192 patients had missing post-treatment biopsies and were considered as having no change in fibrosis/activity scores. In total, 16% of patients receiving PegIFNα-2b and 11% of observation patients had improvement in MFS (p=0.32). More PegIFNα-2b than observation patients had improvement in activity score (20% vs. 9%; p <0.001). Among patients treated for >2.5 years, improvement in MFS or activity score was more common with PegIFNα-2b than observation (21% vs. 14%, p=0.08 and 26% vs. 10%, p <0.001). FibroTest and ActiTest evaluations indicated significant benefit associated with PegIFNα-2b in terms of reduced fibrosis progression and improved activity score. The safety profile of PegIFNα-2b was similar to previous studies. PegIFNα-2b did not significantly improve MFS estimated by biopsy compared with observation; however, activity scores were significantly improved and MFS trended toward increased improvement with treatment durations >2.5 years. Both FibroTest and ActiTest were significantly improved during maintenance therapy. Copyright © 2012 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

Measuring eating disorder attitudes and behaviors: a reliability generalization study

PubMed Central

2014-01-01

Background Although score reliability is a sample-dependent characteristic, researchers often only report reliability estimates from previous studies as justification for employing particular questionnaires in their research. The present study followed reliability generalization procedures to determine the mean score reliability of the Eating Disorder Inventory and its most commonly employed subscales (Drive for Thinness, Bulimia, and Body Dissatisfaction) and the Eating Attitudes Test as a way to better identify those characteristics that might impact score reliability. Methods Published studies that used these measures were coded based on their reporting of reliability information and additional study characteristics that might influence score reliability. Results Score reliability estimates were included in 26.15% of studies using the EDI and 36.28% of studies using the EAT. Mean Cronbach’s alphas for the EDI (total score = .91; subscales = .75 to .89), EAT-40 (total score = .81) and EAT-26 (total score = .86; subscales = .56 to .80) suggested variability in estimated internal consistency. Whereas some EDI subscales exhibited higher score reliability in clinical eating disorder samples than in nonclinical samples, other subscales did not exhibit these differences. Score reliability information for the EAT was primarily reported for nonclinical samples, making it difficult to characterize the effect of type of sample on these measures. However, there was a tendency for mean score reliability to be higher in the adult (vs. adolescent) samples and in female (vs. male) samples. Conclusions Overall, this study highlights the importance of assessing and reporting internal consistency during every test administration because reliability is affected by characteristics of the participants being examined.

On March 11, 2011, Japan was struck by a massive earthquake and tsunami. The tsunami caused tremendous damage and traumatized several people, including children. The aim of this study was to assess changes in traumatic symptoms 8, 20, and 30 months of the 2011 tsunami. The study comprised three groups. Copies of the Post-Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-rating questionnaire on traumatic symptoms, were distributed to 12,524 children (8-month period), 12,193 children (20-month period), and 11,819 children (30-month period). An effective response of children 8 months, 20 months, and 30 month after the disaster was obtained in 11,639 (92.9%), 10,597 (86.9%), and 10,812 children (91.4%), respectively. We calculated the total score, PTSD subscale, and Depression subscale of PTSSC-15. We calculated the total score, PTSD subscale, and Depression subscale of PTSSC-15. The PTSSC-15 total score and PTSD subscale of children belonging to 1st-9th grade groups who were tested 30 and 20 months after the tsunami significantly decreased compared with those of children tested 8 months after the tsunami. The PTSSC-15 total score and PTSD subscale of children in 1st-9th grade groups tested after 30 months did not decrease significantly compared with those of children tested after 20 months. The PTSSC-15 Depression subscale and PTSD subscale of children in 1st-9th grade groups tested after 30 months significantly decreased compared with those of children tested 8 months after the tsunami. The PTSSC-15 Depression subscale of children in 1st-9th grade groups evaluated after 30 months significantly decreased compared with those of children evaluated after 20 months. This study demonstrates that the traumatic symptoms of children who survived the massive tsunami improved with time. Nonetheless, the traumatic symptoms, which in some cases did not improve with time.

To develop and assess structure, test-retest reliability, and discriminative validity of a self-report questionnaire (University of South Australia Urinary Sensation Assessment: USA 2 ) to assess multiple dimensions of urgency sensation. The USA 2 was designed and tested over two prospective, observational studies (2013-2014). Participants were English speaking Australians aged 50 or more with and without overactive bladder (OAB; determined by OAB awareness tool), recruited via health and recreation centers. In Study 1, exploratory factor analysis determined USA 2 structure and subscales. In Study 2, confirmatory factor analysis reassessed structure; Mann-Whitney U-tests determined discriminative validity (OAB vs. non-OAB for subscale and total scores) with Cohen's d effect sizes. Thirty-three individuals completed the USA 2 twice; intraclass correlation coefficients (ICCs) and Wilcoxon signed rank tests assessed test-retest reliability. Questionnaires were returned by 189 eligible participants in Study 1 and 211 in Study 2. Exploratory factor analysis revealed three subscales: "urgency," "affective," "fullness." Confirmatory factor analysis supported these subscales. Subscale and total scores were significantly different between groups with and without OAB (P < 0.001). Cohen's d effect sizes (95%CI) were total score 1.8 (0.5-3.1), "urgency" subscale 1.8 (1.3-2.3), "affective" 1.7 (0.95-2.4), and "fullness" 0.75 (0.42-1.09). Total and subscales scores demonstrated test-retest reliability; ICCs (95%CIs) of 0.95 (0.9-0.98), 0.96 (0.92-0.98), 0.94 (0.88-0.97), and 0.78 (0.56-0.89). The USA 2 assesses multiple dimensions of urgency sensation, is reliable over a 2-week period, and discriminates between older adults with and without OAB. Further validation is required in conditions other than overactive bladder. Neurourol. Urodynam. 36:667-672, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The Relationship Between the Learning Style Perceptual Preferences of Urban Fourth Grade Children and the Acquisition of Selected Physical Science Concepts Through Learning Cycle Instructional Methodology.

NASA Astrophysics Data System (ADS)

Adams, Kenneth Mark

The purpose of this research was to investigate the relationship between the learning style perceptual preferences of fourth grade urban students and the attainment of selected physical science concepts for three simple machines as taught using learning cycle methodology. The sample included all fourth grade children from one urban elementary school (N = 91). The research design followed a quasi-experimental format with a single group, equivalent teacher demonstration and student investigation materials, and identical learning cycle instructional treatment. All subjects completed the Understanding Simple Machines Test (USMT) prior to instructional treatment, and at the conclusion of treatment to measure student concept attainment related to the pendulum, the lever and fulcrum, and the inclined plane. USMT pre and post-test scores, California Achievement Test (CAT-5) percentile scores, and Learning Style Inventory (LSI) standard scores for four perceptual elements for each subject were held in a double blind until completion of the USMT post-test. The hypothesis tested in this study was: Learning style perceptual preferences of fourth grade students as measured by the Dunn, Dunn, and Price Learning Style Inventory (LSI) are significant predictors of success in the acquisition of physical science concepts taught through use of the learning cycle. Analysis of pre and post USMT scores, 18.18 and 30.20 respectively, yielded a significant mean gain of +12.02. A controlled stepwise regression was employed to identify significant predictors of success on the USMT post-test from among USMT pre-test, four CAT-5 percentile scores, and four LSI perceptual standard scores. The CAT -5 Total Math and Total Reading accounted for 64.06% of the variance in the USMT post-test score. The only perceptual element to act as a significant predictor was the Kinesthetic standard score, accounting for 1.72% of the variance. The study revealed that learning cycle instruction does not appear to be sensitive to different perceptual preferences. Students with different preferences for auditory, visual, and tactile modalities, when learning, seem to benefit equally from learning cycle exposure. Increased use of a double blind for future learning styles research was recommended.

The Life-Space Assessment (LSA), developed in the USA, is an instrument focusing on mobility with respect to reaching different areas defined as life-spaces, extending from the room where the person sleeps to mobility outside one's hometown. A newly translated Swedish version of the LSA (LSA-S) has been tested for test-retest reliability, but the validity remains to be tested. The purpose of the present study was to examine the concurrent validity of the LSA-S, by comparing and correlating the LSA scores to other measures of mobility. The LSA was included in a population-based study of health, functioning and mobility among older persons in Sweden, and the present analysis comprised 312 community-dwelling participants. To test the concurrent validity, the LSA scores were compared to a number of other mobility-related variables, including the Short Physical Performance Battery (SPPB) as well as "stair climbing", "transfers", "transportation", "food shopping", "travel for pleasure" and "community activities". The LSA total mean scores for different levels of the other mobility-related variables, and measures of correlation were calculated. Higher LSA total mean scores were observed with higher levels of all the other mobility related variables. Most of the correlations between the LSA and the other mobility variables were large (r = 0.5-1.0) and significant at the 0.01 level. The LSA total score, as well as independent life-space and assistive life-space correlated with transportation (0.63, 0.66, 0.64) and food shopping (0.55, 0.58, 0.55). Assistive life-space also correlated with SPPB (0.47). With respect to maximal life-space, the correlations with the mobility-related variables were generally lower (below 0.5), probably since this aspect of life-space mobility is highly influenced by social support and is not so dependent on the individual's own physical function. LSA was shown to be a valid measure of mobility when using the LSA total, independent LS or assistive LSA.

Multivariate base rates allow for the simultaneous statistical interpretation of multiple test scores, quantifying the normal frequency of low scores on a test battery. This study provides multivariate base rates for the Delis-Kaplan Executive Function System (D-KEFS). The D-KEFS consists of 9 tests with 16 Total Achievement scores (i.e. primary indicators of executive function ability). Stratified by education and intelligence, multivariate base rates were derived for the full D-KEFS and an abbreviated four-test battery (i.e. Trail Making, Color-Word Interference, Verbal Fluency, and Tower Test) using the adult portion of the normative sample (ages 16-89). Multivariate base rates are provided for the full and four-test D-KEFS batteries, calculated using five low score cutoffs (i.e. ≤25th, 16th, 9th, 5th, and 2nd percentiles). Low scores occurred commonly among the D-KEFS normative sample, with 82.6 and 71.8% of participants obtaining at least one score ≤16th percentile for the full and four-test batteries, respectively. Intelligence and education were inversely related to low score frequency. The base rates provided herein allow clinicians to interpret multiple D-KEFS scores simultaneously for the full D-KEFS and an abbreviated battery of commonly administered tests. The use of these base rates will support clinicians when differentiating between normal variations in cognitive performance and true executive function deficits.

A psychometrically constructed short test as a prerequisite for screening was developed on the basis of a revision of the Marburger Speech Screening to assess speech/language competence among children in Hessen (Germany). A total of 257 children (age 4.0 to 4.5 years) performed the test battery for speech/language competence; 214 children repeated the test 1 year later. Test scores correlated highly with scores of two competing language screenings (SSV, HASE) and with a combined score from four diagnostic tests of individual speech/language competences (Reynell III, patholinguistic diagnostics in impaired language development, PLAKSS, AWST-R). Validity was demonstrated by three comparisons: (1) Children with German family language had higher scores than children with another language. (2) The 3-month-older children achieved higher scores than younger children. (3) The difference between the children with German family language and those with another language was higher for the 3-month-older than for the younger children. The short test assesses the speech/language competence of 4-year-olds quickly, validly, and comprehensively.

Verification of learner’s differences by team-based learning in biochemistry classes

2017-01-01

Purpose We tested the effect of team-based learning (TBL) on medical education through the second-year premedical students’ TBL scores in biochemistry classes over 5 years. Methods We analyzed the results based on test scores before and after the students’ debate. The groups of students for statistical analysis were divided as follows: group 1 comprised the top-ranked students, group 3 comprised the low-ranked students, and group 2 comprised the medium-ranked students. Therefore, group T comprised 382 students (the total number of students in group 1, 2, and 3). To calibrate the difficulty of the test, original scores were converted into standardized scores. We determined the differences of the tests using Student t-test, and the relationship between scores before, and after the TBL using linear regression tests. Results Although there was a decrease in the lowest score, group T and 3 showed a significant increase in both original and standardized scores; there was also an increase in the standardized score of group 3. There was a positive correlation between the pre- and the post-debate scores in group T, and 2. And the beta values of the pre-debate scores and “the changes between the pre- and post-debate scores” were statistically significant in both original and standardized scores. Conclusion TBL is one of the educational methods for helping students improve their grades, particularly those of low-ranked students. PMID:29207457

Background Preoperative expectations of outcome of total hip and knee arthroplasty are important determinants of patients' satisfaction and functional outcome. Aims of the study were (1) to translate the Hospital for Special Surgery Hip Replacement Expectations Survey and Knee Replacement Expectations Survey into Dutch and (2) to study test-retest reliability and concurrent validity. Methods Patients scheduled for total hip (N = 112) or knee replacement (N = 101) were sent the Dutch Expectations Surveys twice with a 2 week interval to determine test-retest reliability. To determine concurrent validity, the Expectation WOMAC was sent. Results The results for the Dutch Hip Replacement Expectations Survey revealed good test-retest reliability (ICC 0.87), no bias and good internal consistency (alpha 0.86) (N = 72). The correlation between the Hip Expectations Score and the Expectation WOMAC score was 0.59 (N = 86). The results for the Dutch Knee Replacement Expectations Survey revealed good test-retest reliability (ICC 0.79), no bias and good internal consistency (alpha 0.91) (N = 46). The correlation with the Expectation WOMAC score was 0.52 (N = 57). Conclusions Both Dutch Expectations Surveys are reliable instruments to determine patients' expectations before total hip or knee arthroplasty. As for concurrent validity, the correlation between both surveys and the Expectation WOMAC was moderate confirming that the same construct was determined. However, patients scored systematically lower on the Expectation WOMAC compared to the Dutch Expectation Surveys. Research on patients' expectations before total hip and knee replacement has only been performed in a limited amount of countries. With the Dutch Expectations Surveys it is now possible to determine patients' expectations in another culture and healthcare setting. PMID:20958990

Objective: To study the concurrent and construct validity and test-retest reliability in the practice setting of an outcome measure for myasthenia gravis (MG). Methods: Eleven centers participated in the validation study of the Myasthenia Gravis Composite (MGC) scale. Patients with MG were evaluated at 2 consecutive visits. Concurrent and construct validities of the MGC were assessed by evaluating MGC scores in the context of other MG-specific outcome measures. We used numerous potential indicators of clinical improvement to assess the sensitivity and specificity of the MGC for detecting clinical improvement. Test-retest reliability was performed on patients at the University of Virginia. Results: A total of 175 patients with MG were enrolled at 11 sites from July 1, 2008, to January 31, 2009. A total of 151 patients were seen in follow-up. Total MGC scores showed excellent concurrent validity with other MG-specific scales. Analyses of sensitivities and specificities of the MGC revealed that a 3-point improvement in total MGC score was optimal for signifying clinical improvement. A 3-point improvement in the MGC also appears to represent a meaningful improvement to most patients, as indicated by improved 15-item myasthenia gravis quality of life scale (MG-QOL15) scores. The psychometric properties were no better for an individualized subscore made up of the 2 functional domains that the patient identified as most important to treat. The test-retest reliability coefficient of the MGC was 98%, with a lower 95% confidence interval of 97%, indicating excellent test-retest reliability. Conclusions: The Myasthenia Gravis Composite is a reliable and valid instrument for measuring clinical status of patients with myasthenia gravis in the practice setting and in clinical trials.

Before starting the implementation of integrated hospital information systems, the physicians' and nurses' attitudes towards computers were measured by means of a questionnaire. The study was conducted in Dubrava University Hospital, Zagreb in Croatia. Out of 194 respondents, 141 were nurses and 53 physicians, randomly selected. They surveyed by an anonymous questionnaire consisting of 8 closed questions about demographic data, computer science education and computer usage, and 30 statements on attitudes towards computers. The statements were adapted to a Likert type scale. Differences in attitudes towards computers between groups were compared using Kruskal-Wallis and Mann Whitney test for post-hoc analysis. The total score presented attitudes toward computers. Physicians' total score was 130 (97-144), while nurses' total score was 123 (88-141). It points that the average answer to all statements was between "agree" and "strongly agree", and these high total scores indicated their positive attitudes. Age, computer science education and computer usage were important factors witch enhances the total score. Younger physicians and nurses with computer science education and with previous computer experience had more positive attitudes towards computers than others. Our results are important for planning and implementation of integrated hospital information systems in Croatia.

A general equation to obtain multiple cut-off scores on a test from multinomial logistic regression.

PubMed

Bersabé, Rosa; Rivas, Teresa

2010-05-01

The authors derive a general equation to compute multiple cut-offs on a total test score in order to classify individuals into more than two ordinal categories. The equation is derived from the multinomial logistic regression (MLR) model, which is an extension of the binary logistic regression (BLR) model to accommodate polytomous outcome variables. From this analytical procedure, cut-off scores are established at the test score (the predictor variable) at which an individual is as likely to be in category j as in category j+1 of an ordinal outcome variable. The application of the complete procedure is illustrated by an example with data from an actual study on eating disorders. In this example, two cut-off scores on the Eating Attitudes Test (EAT-26) scores are obtained in order to classify individuals into three ordinal categories: asymptomatic, symptomatic and eating disorder. Diagnoses were made from the responses to a self-report (Q-EDD) that operationalises DSM-IV criteria for eating disorders. Alternatives to the MLR model to set multiple cut-off scores are discussed.

Palliative care education for health care professionals is a key element in improving access to quality palliative care. The Palliative Care Emphasis Program on Symptom Management and Assessment for Continuous Medical Education (PEACE) was designed to provide educational opportunities for all physicians in Japan. As of 2015, 57,764 physicians had completed it. The objective of this study was to estimate the effects of the program. This study was an analysis of 2 nationwide observational studies from 2008 and 2015. We conducted 2 questionnaire surveys for representative samples of physicians. The measurements used were the Palliative Care Knowledge Test (range, 0-100) and the Palliative Care Difficulties Scale (range, 1-4). Comparisons were made with the unpaired Student t test and with a multivariate linear regression model using 2 cohorts and a propensity score-matched sample. This study analyzed a total of 48,487 physicians in 2008 and a total of 2720 physicians in 2015. Between 2008 and 2015, physicians' knowledge and difficulties significantly improved on the Palliative Care Knowledge Test with total scores of 68 and 78, respectively (P < .001; effect size, 0.40) and on the Palliative Care Difficulties Scale with total scores of 2.65 and 2.49, respectively (P < .001; effect size, 0.29). Propensity-score matching resulted in 619 untrained physicians matched to 619 trained physicians, and physicians who trained with the PEACE program had a higher knowledge score (74 vs 86; P < .001; effect size, 0.64) and a lower difficulties score (2.6 vs 2.3; P < .001; effect size, 0.42). Physicians' knowledge of and difficulties with palliative care improved on a national level. The PEACE program may have contributed to these improvements.

Retrospective review. To compare surgical outcomes of patients who have undergone anterior lumbar interbody fusion (ALIF) with and without plating. In biomechanical testing, ALIF constructs supplemented with plating (ALIFP) reduce range of motion and increase construct stiffness compared with ALIF alone. However, whether ALIFP constructs translate into improved clinical outcomes over ALIF alone is unknown. From 2004 through 2010, 231 patients underwent ALIF with (146) or without (85) plating. Eight patients lost to follow up were excluded from final evaluation. Patients' records were evaluated retrospectively for demographics, complications, and outcomes. At a mean follow-up of 13.7 months (range, 1-108 mo), the mean Economic, Functional, and Total Prolo scores for ALIF patients were 4.23, 3.63, and 7.87, respectively. The mean Oswestry Disability Index (ODI) was 24%. At a mean follow-up of 11.2 months (range, 1-93 mo), the mean Economic, Functional, and Total Prolo scores for ALIFP patients were 4.28, 3.67, and 7.95, respectively. The mean ODI was 22.9%. There was no significant difference between rate of complications or Prolo scores or ODI between the 2 groups (t test). Neither diabetes, hypertension, smoking, sex, nor age older than 55 years was significantly related to whether patients had higher Prolo scores with or without plating. Patients with a normal body mass index and ALIF had significantly better Prolo Economic scores and total scores than patients with a normal body mass index and ALIFP (P=0.04 and 0.02, independent samples t test). Patients were also stratified by surgical indication for surgery, and there was no significant difference in Prolo scores or ODI for patients who underwent ALIF alone versus ALIFP. Even when stratified by indication for surgery, anterior plating does not seem to improve Prolo scores or ODI, suggesting that not all patients undergoing ALIF require plating.

Testing a computer-based ostomy care training resource for staff nurses.

Bales, Isabel

2010-05-01

Fragmented teaching and ostomy care provided by nonspecialized clinicians unfamiliar with state-of-the-art care and products have been identified as problems in teaching ostomy care to the new ostomate. After conducting a literature review of theories and concepts related to the impact of nurse behaviors and confidence on ostomy care, the author developed a computer-based learning resource and assessed its effect on staff nurse confidence. Of 189 staff nurses with a minimum of 1 year acute-care experience employed in the acute care, emergency, and rehabilitation departments of an acute care facility in the Midwestern US, 103 agreed to participate and returned completed pre- and post-tests, each comprising the same eight statements about providing ostomy care. F and P values were computed for differences between pre- and post test scores. Based on a scale where 1 = totally disagree and 5 = totally agree with the statement, baseline confidence and perceived mean knowledge scores averaged 3.8 and after viewing the resource program post-test mean scores averaged 4.51, a statistically significant improvement (P = 0.000). The largest difference between pre- and post test scores involved feeling confident in having the resources to learn ostomy skills independently. The availability of an electronic ostomy care resource was rated highly in both pre- and post testing. Studies to assess the effects of increased confidence and knowledge on the quality and provision of care are warranted.

The Rivermead Behavioural Memory Test (RBMT) is a short, ecologically-valid memory test battery that can provide data about a subject's memory function in daily life. We used RBMT to examine daily memory function in patients with mild cognitive impairment (MCI), Alzheimer disease (AD), and in healthy controls. We also evaluated differences between the memory profiles of subjects whose MCI remained stable after 1 year and those with conversion to AD. Sample of 91 subjects older than 60 years: 30 controls, 27 MCI subjects and 34 AD patients. Subjects were assessed using MMSE and RBMT. The 40 men and 51 women in the sample had a mean age of 74.29±6.71 and 5.87±2.93 years of education. For the total profile and screening RBMT scores (P<.001) and total MMSE scores (P<.05), control subjects scored significantly higher than those with MCI, who in turn scored higher than AD patients. In all subtests, the control group (P<.001) and MCI group (P<.05) were distinguishable from the AD group. Prospective, retrospective, and orientation subtests found differences between the MCI and control groups (P<.05). MCI subjects who progressed to AD scored lower at baseline on the total RBMT and MMSE, and on name recall, belongings, story-immediate recall, route-delayed recall, orientation (P<.05), face recognition, story-delayed recall, and messages-delayed recall sections (P<.01). RBMT is an ecologically-valid episodic memory test that can be used to differentiate between controls, MCI subjects, and AD subjects. It can also be used to detect patients with MCI who will experience progression to AD. Copyright © 2012 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

To describe the sensitivity and specificity of Coma Recovery Scale-Revised (CRS-R) total scores in detecting conscious awareness. Data were retrospectively extracted from the medical records of patients enrolled in a specialized disorders of consciousness (DOC) program. Sensitivity and specificity analyses were completed using CRS-R-derived diagnoses of minimally conscious state (MCS) or emerged from minimally conscious state (EMCS) as the reference standard for conscious awareness and the total CRS-R score as the test criterion. A receiver operating characteristic curve was constructed to demonstrate the optimal CRS-R total cutoff score for maximizing sensitivity and specificity. Specialized DOC program. Patients enrolled in the DOC program (N=252, 157 men; mean age, 49y; mean time from injury, 48d; traumatic etiology, n=127; nontraumatic etiology, n=125; diagnosis of coma or vegetative state, n=70; diagnosis of MCS or EMCS, n=182). Not applicable. Sensitivity and specificity of CRS-R total scores in detecting conscious awareness. A CRS-R total score of 10 or higher yielded a sensitivity of .78 for correct identification of patients in MCS or EMCS, and a specificity of 1.00 for correct identification of patients who did not meet criteria for either of these diagnoses (ie, were diagnosed with vegetative state or coma). The area under the curve in the receiver operating characteristic curve analysis is .98. A total CRS-R score of 10 or higher provides strong evidence of conscious awareness but resulted in a false-negative diagnostic error in 22% of patients who demonstrated conscious awareness based on CRS-R diagnostic criteria. A cutoff score of 8 provides the best balance between sensitivity and specificity, accurately classifying 93% of cases. The optimal total score cutoff will vary depending on the user's objective.

To assess for usefulness and validity evidence for incorporating the C-Arm Trainer (CAT) simulator into the annual AUA hands on course for training percutaneous nephrolithotomy (PCNL). The course started with a didactic session followed by four stations for training the "bull's eye" technique using the CAT simulator. Each station included a pre-test, 30-min practice on the simulator, and post-test. All participants were assessed using a 4-item checklist. All participants were asked to fill in a qualitative self-assessment questionnaire after the pre- and the post-test, and respond to a course evaluation questionnaire and post-course survey. A total of 38 physicians, who attended the hands on course, voluntarily participated in the study. Only 21.1% had previous practice on PCNL simulators. Compared with the results of the checklist total score and the qualitative self-assessment questionnaire scores after the pre-test, there was significant improvement in the checklist total score (p < 0.001), temporal demands (p = 0.003), situational stress (p = 0.003, and performance (0.003) after the post-test. A total of 14 (36%) participants responded to the course evaluation questionnaire, 50% evaluated the course as excellent, 28.6% as very good, and 21.4% as good. Unfortunately, only five (13%) participants responded to the post-course survey, 4/5 implemented the new competencies and knowledge into their practice, and 3/5 have attempted to obtain fluoroscopic guided PCA without assistance. The CAT simulator was considered useful for training the percutaneous renal access procedure. There was significant improvement in the qualitative and quantitative assessment parameters after the post-test compared with the pre-test.

Patients with polycystic ovary syndrome (PCOS) report a decreased health-related quality of life (HRQOL) and higher levels of psychological distress. Validated questionnaires are necessary to assess the impact of PCOS on patients' lives. The aim of the present study was to evaluate the German "Polycystic Ovary Syndrome Questionnaire" (PCOSQ-G). The psychometric properties of the PCOSQ-G were investigated in PCOS patients with item-total correlation, internal consistency and test-retest reliability. Correlations with the Short-Form-36 Health Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS-D) were calculated to evaluate the validity of the PCOSQ-G. Discriminatory validity was investigated through a receiver operating characteristic curve and independent sample t tests compared with healthy controls. Good psychometric properties were found for most items. Acceptable to high internal consistency was found for the total score (α = 0.94-0.95) and all subscales (α = 0.70-0.97). High test-retest reliability was found for the total score (0.86) and all subscales (0.81-0.90). The validity analyses showed that the PCOSQ-G total score was positively correlated with both SF-36 summary scales and was negatively correlated with both HADS subscales. Patients reported significantly lower values for the PCOSQ-G total score (p < 0.001) and all subscales, and the PCOSQ-G discriminated well between patients and healthy controls (AUC = 0.81, p < 0.001). PCOSQ-G is a reliable and valid tool to assess the HRQOL in patients with PCOS and can be used in future clinical research. Patients with PCOS exhibited an impaired HRQOL, which indicates the need for psychosomatic counseling.

The aim of this study was to examine the effects of home and educational environments on children's motor performance in China. We conducted a cross-sectional study of 4001 preschool children selected from 160 classes. The children's motor performance was assessed using the Movement Assessment Battery for Children, 2nd edition (MABC-2). Home and educational environments were evaluated using validated checklists. The effects of home and educational environments on motor performance were analysed using mixed and multilevel logistic regression models. The results showed that one score increase in the outside space of the family home was positively associated with the increase in total test score (0.104) subtest score of aiming and catching (0.037), and balance (0.034) of the MABC-2, after adjusting for potential confounders (each p<0.05). Possession of motor toys at home and parental rearing behaviours were also related to total test score, manual dexterity, and balance (β=0.022-0.104, each p<0.05). Space and furnishings, activity, and interaction in the classroom had a significant positive association with total test score (β=0.069-0.201), and with subtest scores of manual dexterity, aiming and catching, and balance respectively (β=0.115-0.206). Space and furnishings of classrooms and possession of toys in the household were protective factors for 'at risk' or significant poor performance (odds ratio 0.942-0.973, each p<0.05). A permissive and accepting family and educational environment made a positive contribution to children's motor performance. Access to sufficient space and furnishings within the classroom, as well as toys in the family, were protective factors for poor motor performance. Future assistance is needed to support an advantageous environment in early childhood programmes in China. © 2016 Mac Keith Press.

The purpose of this study was to translate the Oxford hip score (OHS) into Turkish and to evaluate the psychometric properties by testing the internal consistency, reproducibility, construct validity, and responsiveness in patients with hip osteoarthritis (OA). Oxford hip score was translated and culturally adapted according to the guidelines in the literature. Seventy patients (mean age 61.45 ± 9.29 years) with hip osteoarthritis participated in the study. Patients completed the Turkish Oxford hip score (OHS-TR), the Short-Form 36 (SF-36), and Western Ontario and McMaster Universities Index (WOMAC). Internal consistency was tested using Cronbach's α coefficient. Patients completed OHS-TR questionnaire twice in 7 days for determining the reproducibility. Correlation between the total results of both tests was determined by the Pearson correlation coefficient and intraclass correlation coefficient (ICC). Validity was assessed by calculating the Pearson correlation coefficient between the OHS-TR and WOMAC and SF-36 scores. Floor and ceiling effects were analyzed. The internal consistency was high (Cronbach's α 0.93). The construct validity showed a significant correlation between the OHS-TR and WOMAC and related SF-36 domains (p < 0.001). The ICC's ranged between 0.80 and 0.99. There was no floor or ceiling effect in total OHS-TR score. The OHS-TR questionnaire is valid, reliable, and responsive for the Turkish-speaking patients with hip OA.

Emotional intelligence in orthopedic surgery residents.

Chan, Kevin; Petrisor, Brad; Bhandari, Mohit

Emotional intelligence (EI) is the ability to understand and manage emotions in oneself and others. It was originally popularized in the business literature as a key attribute for success that was distinct from cognitive intelligence. Increasing focus is being placed on EI in medicine to improve clinical and academic performance. Despite the proposed benefits, to our knowledge, there have been no previous studies on the role of EI in orthopedic surgery. We evaluated baseline data on EI in a cohort of orthopedic surgery residents. We asked all orthopedic surgery residents at a single institution to complete an electronic version of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). We used completed questionnaires to calculate total EI scores and 4 branch scores. Data were analyzed according to a priori cutoff values to determine the proportion of residents who were considered competent on the test. Data were also analyzed for possible associations with age, sex, race and level of training. Thirty-nine residents (100%) completed the MSCEIT. The mean total EI score was 86 (maximum score 145). Only 4 (10%) respondents demonstrated competence in EI. Junior residents (p = 0.026), Caucasian residents (p = 0.009) and those younger than 30 years (p = 0.008) had significantly higher EI scores. Our findings suggest that orthopedic residents score low on EI based on the MSCEIT. Optimizing resident competency in noncognitive skills may be enhanced by dedicated EI education, training and testing.

This study evaluated the effectiveness of a brief intervention (BI) for illicit drugs (cannabis, cocaine, amphetamine-type stimulants and opioids) linked to the World Health Organization (WHO) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). The ASSIST screens for problem or risky use of 10 psychoactive substances, producing a score for each substance that falls into either a low-, moderate- or high-risk category. Prospective, randomized controlled trial in which participants were either assigned to a 3-month waiting-list control condition or received brief motivational counselling lasting an average of 13.8 minutes for the drug receiving the highest ASSIST score. Primary health-care settings in four countries: Australia, Brazil, India and the United States. A total of 731 males and females scoring within the moderate-risk range of the ASSIST for cannabis, cocaine, amphetamine-type stimulants or opioids. ASSIST-specific substance involvement scores for cannabis, stimulants or opioids and ASSIST total illicit substance involvement score at baseline and 3 months post-randomization. Omnibus analyses indicated that those receiving the BI had significantly reduced scores for all measures, compared with control participants. Country-specific analyses showed that, with the exception of the site in the United States, BI participants had significantly lower ASSIST total illicit substance involvement scores at follow-up compared with the control participants. The sites in India and Brazil demonstrated a very strong brief intervention effect for cannabis scores (P < 0.005 for both sites), as did the sites in Australia (P < 0.005) and Brazil (P < 0.01) for stimulant scores and the Indian site for opioid scores (P < 0.01). The Alcohol, Smoking and Substance Involvement Screening Test-linked brief intervention aimed at reducing illicit substance use and related risks is effective, at least in the short term, and the effect generalizes across countries. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

2016-01-01

To fill an important gap in the psychometric assessment of children and adolescents with impaired vision, we designed a new battery of haptic tests, called Haptic-2D, for visually impaired and sighted individuals aged five to 18 years. Unlike existing batteries, ours uses only two-dimensional raised materials that participants explore using active touch. It is composed of 11 haptic tests, measuring scanning skills, tactile discrimination skills, spatial comprehension skills, short-term tactile memory, and comprehension of tactile pictures. We administered this battery to 138 participants, half of whom were sighted (n=69), and half visually impaired (blind, n=16; low vision, n=53). Results indicated a significant main effect of age on haptic scores, but no main effect of vision or Age × Vision interaction effect. Reliability of test items was satisfactory (Cronbach's alpha, α=0.51-0.84). Convergent validity was good, as shown by a significant correlation (age partialled out) between total haptic scores and scores on the B101 test (rp=0.51, n=47). Discriminant validity was also satisfactory, as attested by a lower but still significant partial correlation between total haptic scores and the raw score on the verbal WISC (rp=0.43, n=62). Finally, test-retest reliability was good (rs=0.93, n=12; interval of one to two months). This new psychometric tool should prove useful to practitioners working with young people with impaired vision. Copyright © 2015 Elsevier Ltd. All rights reserved.

We provide a tutorial on differential item functioning (DIF) analysis, an analytic method useful for identifying potentially biased items in assessments. After explaining a number of methodological approaches, we test for gender bias in two scenarios that demonstrate why DIF analysis is crucial for developing assessments, particularly because simply comparing two groups’ total scores can lead to incorrect conclusions about test fairness. First, a significant difference between groups on total scores can exist even when items are not biased, as we illustrate with data collected during the validation of the Homeostasis Concept Inventory. Second, item bias can exist even when the two groups have exactly the same distribution of total scores, as we illustrate with a simulated data set. We also present a brief overview of how DIF analysis has been used in the biology education literature to illustrate the way DIF items need to be reevaluated by content experts to determine whether they should be revised or removed from the assessment. Finally, we conclude by arguing that DIF analysis should be used routinely to evaluate items in developing conceptual assessments. These steps will ensure more equitable—and therefore more valid—scores from conceptual assessments. PMID:28572182

Objective To validate manual muscle testing (MMT) for strength assessment in juvenile and adult dermatomyositis (DM) and polymyositis (PM). Methods Seventy-three children and 45 adult DM/PM patients were assessed at baseline and reevaluated 6–9 months later. We compared Total MMT (a group of 24 proximal, distal, and axial muscles) and Proximal MMT (7 proximal muscle groups) tested bilaterally on a 0–10 scale with 144 subsets of six and 96 subsets of eight muscle groups tested unilaterally. Expert consensus was used to rank the best abbreviated MMT subsets for face validity and ease of assessment. Results The Total, Proximal and best MMT subsets had excellent internal reliability (rs:Total MMT 0.91–0.98), and consistency (Cronbach’s α 0.78–0.97). Inter- and intra-rater reliability were acceptable (Kendall’s W 0.68–0.76; rs 0.84–0.95). MMT subset scores correlated highly with Total and Proximal MMT scores and with the Childhood Myositis Assessment Scale, and correlated moderately with physician global activity, functional disability, magnetic resonance imaging, axial and distal MMT scores and, in adults, with creatine kinase. The standardized response mean for Total MMT was 0.56 in juveniles and 0.75 in adults. Consensus was reached to use a subset of eight muscles (neck flexors, deltoids, biceps, wrist extensors, gluteus maximus and medius, quadriceps and ankle dorsiflexors) that performed as well as the Total and Proximal MMT, and had good face validity and ease of assessment. Conclusions These findings aid in standardizing the use of MMT for assessing strength as an outcome measure for myositis. PMID:20391500

Psychometric Properties of the Autism-Spectrum Quotient for Assessing Low and High Levels of Autistic Traits in College Students.

Stevenson, Jennifer L; Hart, Kari R

2017-06-01

The current study systematically investigated the effects of scoring and categorization methods on the psychometric properties of the Autism-Spectrum Quotient. Four hundred and three college students completed the Autism-Spectrum Quotient at least once. Total scores on the Autism-Spectrum Quotient had acceptable internal consistency and test-retest reliability using a binary or Likert scoring method, but the results were more varied for the subscales. Overall, Likert scoring yielded higher internal consistency and test-retest reliability than binary scoring. However, agreement in categorization of low and high autistic traits was poor over time (except for a median split on Likert scores). The results support using Likert scoring and administering the Autism-Spectrum Quotient at the same time as the task of interest with neurotypical participants.

To evaluate the quality of life (QOL) of overweight and obese middle or high school students and identify relevant factors influencing their QOL scores. 716 students were recruited from 6 middle or high schools in Hangzhou, China. The Chinese version of the Youth Quality of Life Instrument-Weight Module (YQOL-W) was self administered. The YQOL-W scores were compared among different BMI groups, gender, educational status, annual household income, parental education and recruitment community using t test or one-way analysis of variance. The independent association of these variables with QOL among overweight and obese students was examined using multivariable linear regression modeling. Overweight and obese students reported lower total scores, self, social and environment scores than their normal weight peers (all P<0.001). The QOL of overweight and obese middle and high school students was associated with BMI value, gender, educational status, parental education, and recruitment community. Girls had lower total scores, self, social and environment domain scores than boys (all P<0.001); high school students had lower total and three domain scores than middle school students (all P<0.05). Students whose fathers had higher education reported higher total scores, self and social scores than students with less educated fathers (all P<0.05). Students whose mothers had higher education reported higher environment scores than students with less educated mothers (P = 0.01). Students from migrant communities reported significantly lower total scores, self and social scores than those from rural communities (all P<0.05), but comparable scores with those from urban communities (P>0.05). Students from migrant communities reported comparable environment scores with those from rural and urban communities (P>0.05). Overweight and obesity have negative effects on students' quality of life. Therefore weight specific QOL could be included in weight reduction interventions as a relevant outcome.

It is expected that nursing education improves abilities of students in solving problems, decision making and critical thinking in different circumstances. This study was performed to analyse the effects of care plans prepared using concept maps on the critical thinking dispositions of students. An experimental group and a control group were made up of a total of 80 freshman and sophomore students from the nursing department of a health school. The study used a pre-test post-test control group design. The critical thinking dispositions of the groups were measured using the California Critical Thinking Disposition Inventory. In addition, the care plans prepared by the experimental group students were evaluated using the criteria for evaluating care plans with concept maps. T-test was used in analysing the data. The results showed that there were no statistically significant differences in the total and sub-scale pre-test scores between the experimental group and control group students. There were also significant differences in the total and sub-scale post-test scores between the experimental group and control group students. There were significant differences between concept map care plan evaluation criteria mean scores of the experimental students. In the light of these findings, it could be argued that the concept mapping strategy improves critical thinking skills of students. © 2012 Blackwell Publishing Asia Pty Ltd.

The aim of this study was to develop and validate a bedside test for executive function in patients with idiopathic normal pressure hydrocephalus (INPH). Twenty consecutive patients with INPH and 20 patients with Alzheimer's disease (AD) were enrolled in this study. We developed the counting-backward test for evaluating executive function in patients with INPH. Two indices that are considered to be reflective of the attention deficits and response suppression underlying executive dysfunction in INPH were calculated: the first-error score and the reverse-effect index. Performance on both the counting-backward test and standard neuropsychological tests for executive function was assessed in INPH and AD patients. The first-error score, reverse-effect index and the scores from the standard neuropsychological tests for executive function were significantly lower for individuals in the INPH group than in the AD group. The two indices for the counting-backward test in the INPH group were strongly correlated with the total scores for Frontal Assessment Battery and Phonemic Verbal Fluency. The first-error score was also significantly correlated with the error rate of the Stroop colour-word test and the score of the go/no-go test. In addition, we found that the first-error score highly distinguished patients with INPH from those with AD using these tests. The counting-backward test is useful for evaluating executive dysfunction in INPH and for differentiating between INPH and AD patients. In particular, the first-error score may reflect deficits in the response suppression related to executive dysfunction in INPH. © 2012 John Wiley & Sons A/S.

The concept of well-being which focuses on positive emotions has received increased research attention. However, a consensus definition of this term is lacking. The Well-Being Index scale (WHO-5) is a generic, self-report scale that contains five Likert-type items to evaluate psychological well-being. This construct may provide a relevant outcome in bipolar disorder (BD) research and care beyond the rating of mood symptoms. Thus, in the current study, the psychometric properties of the WHO-5 Spanish version were assessed in a sample of euthymic patients with BD. Patients with BD- I and BD-II and healthy controls completed the Well-Being Index (WHO-5) together with an assessment of depressive (Hamilton Depression Rating Scale-17; HAM-D) and manic symptoms (Young Mania Rating Scale; YMRS); and a measure of psychosocial functioning (Functioning Assessment Short Test; FAST). Internal consistency reliability was measured through Cronbach's alpha. Test-retest reliability was calculated comparing the WHO-5 total score at baseline and after 10 days of the first administration. To assess the structure of the scale, a principal component analysis (PCA) was carried out. Correlations between the WHO-5, HAM-D, YMRS and FAST were calculated. Finally, a t-test for independent samples was applied to compare the WHO-5 total score in the patient and control groups. A total of 104 patients with BD and 40 healthy controls were included in this study. A Chronbach's alpha of 0.83 indicated acceptable internal consistency. A paired sample t-test revealed no significant differences between WHO-5 total score at baseline and at follow-up (tn = - 0.72; df = 15; p = 0.48). The PCA provided a single factor solution that accounted for 59.74% of the variation in WHO-5. Test-retest reliability was high (r = 0.83; p < 0.001). Moderate negative correlations were observed between the WHO-5 total score, the FAST (r = - 0.46.; p < 0.001) and the HAM-D (r = - 0.68; p < 0.001), but not with the YMRS (r = - 0.07; p = 0.42). Finally, significant differences were found when comparing the WHO-5 total score between patient and healthy controls (t = 5.1; df = 147; p < 0.001). some limitations include the lack of a comparator scale to test for validity construct and the small sample size in the test-retest reliability CONCLUSIONS: The WHO-5 shows an acceptable reliability index and measures a unitary construct in a Spanish population of euthymic patients with BD.

Women with polycystic ovary syndrome (PCOS) are reported to experience depressive episodes at a higher rate than healthy controls (HC). Affective temperament features are psychiatric markers that may help to predict and identify vulnerability to depression in women with PCOS. Our aim was to evaluate the affective temperaments of women with PCOS and to investigate the association with depression and anxiety levels and laboratory variables in comparison with HC. The study included 71 women with PCOS and 50 HC. Hormonal evaluations were performed for women with PCOS. Physical examination, clinical history, Hospital Anxiety and Depression Scale (HADS) and TEMPS-A were performed for all subjects. Differences between groups were evaluated using Student's t-tests and Mann-Whitney U tests. Correlations and logistic regression tests were performed. All temperament subtype scores, except hyperthymic, and HADS anxiety, depression, and total scores were significantly higher in patients with PCOS compared to HC. A statistically significant positive correlation was found between BMI and irritable temperament, and insulin and HADS depression scores in patients with PCOS. Additionally, hirsutism score and menstrual irregularity were correlated with HADS depression, anxiety and total scores in PCOS patients. In logistic regression analysis, depression was not affected by PCOS, hirsutism score or menstrual irregularity. However, HADS anxiety score was associated with hirsutism score. Our study is the first to evaluate the affective temperament features of women with PCOS. Consequently, establishing affective temperament properties for women with PCOS may help clinicians predict those patients with PCOS who are at risk for depressive and anxiety disorders.

Embedded performance validity tests (PVTs) allow for continuous assessment of invalid performance throughout neuropsychological test batteries. This study evaluated the utility of the Wechsler Memory Scale-Fourth Edition (WMS-IV) Logical Memory (LM) Recognition score as an embedded PVT using the Advanced Clinical Solutions (ACS) for WAIS-IV/WMS-IV Effort System. This mixed clinical sample was comprised of 97 total participants, 71 of whom were classified as valid and 26 as invalid based on three well-validated, freestanding criterion PVTs. Overall, the LM embedded PVT demonstrated poor concordance with the criterion PVTs and unacceptable psychometric properties using ACS validity base rates (42% sensitivity/79% specificity). Moreover, 15-39% of participants obtained an invalid ACS base rate despite having a normatively-intact age-corrected LM Recognition total score. Receiving operating characteristic curve analysis revealed a Recognition total score cutoff of < 61% correct improved specificity (92%) while sensitivity remained weak (31%). Thus, results indicated the LM Recognition embedded PVT is not appropriate for use from an evidence-based perspective, and that clinicians may be faced with reconciling how a normatively intact cognitive performance on the Recognition subtest could simultaneously reflect invalid performance validity.

The UCSD Performance-based Skills Assessment (UPSA) is a widely used measure of functional capacity with strong reliability and validity. However there is a lack of psychometric data on Hispanics. The purpose of this study was to determine the impact of acculturation and education on UPSA performance among 62 Hispanic participants with schizophrenia or schizoaffective disorder and 46 healthy comparison subjects. Functional capacity was measured using the UPSA. Acculturation was measured using the Acculturation Rating Scale for Mexican Americans (ARSMA). Independent t-tests indicated that participants with schizophrenia had significantly lower UPSA total scores and scored lower on all UPSA sub-scales relative to the comparison group. Multiple regression also indicated that education and acculturation were significant predictors of UPSA total scores. These data provide a better understanding of UPSA scores in Hispanics with and without schizophrenia, and suggest that education and acculturation adjustments may be required to improve interpretation of test results.

Nurses play the key role in prevention of pressure ulcers, and negative attitudes of them may affect preventive care strategies. This research aimed to identify surgical nurses' attitudes towards pressure ulcer prevention. A descriptive and cross-sectional study design was used to collect data between March 31-May 16, 2016 on 101 voluntary nurses (66.01% of all nurses) working in surgical units of a university hospital in Turkey. "Attitude towards Pressure Ulcer Prevention Instrument" and "Nurse Information Form" were used to investigate nurses' attitude toward preventing pressure ulcer. Descriptive statistics, Mann-Whitney U test, independent samples t-test, Pearson's chi-squared, and correlation tests were used to analyse the data. The mean age of nurses' was 32.0 ± 6.3 years and, the average duration of clinical experience was 72.3 ± 61 months. A total of 54.5% were working in surgical wards and, 40.6% gained additional education about pressure ulcer care. The mean total attitude score was found to be 80.5% (41.8 ± 4.8). Previous education significantly affected the total attitude score of nurses (p < 0.05). The total scale score showed that surgical nurses had a positive attitude towards pressure ulcer prevention and nurses who had previous education about pressure ulcer care has higher attitude score than who had not. It is recommended that effective in-service education programs be developed at hospitals or that nurses be required to attend courses to help them to improve their pressure ulcer care.

Chronic kidney disease (CKD) is a serious public health problem in Taiwan and the world. The most effective, affordable treatments involve early prevention/detection/intervention, requiring screening. Successfully implementing CKD programs requires good patient participation, affected by patient perceptions of screening service quality. Service quality improvements can help make such programs more successful. Thus, good tools for assessing service quality perceptions are important. to investigate using a modified SERVQUAL questionnaire in assessing patient expectations, perceptions, and loyalty towards kidney disease screening service quality. 1595 kidney disease screening program patients in Taichung City were requested to complete and return a modified kidney disease screening SERVQUAL questionnaire. 1187 returned them. Incomplete ones (102) were culled and 1085 were chosen as effective for use. Paired t-tests, correlation tests, ANOVA, LSD test, and factor analysis identified the characteristics and factors of service quality. The paired t-test tested expectation score and perception score gaps. A structural equation modeling system examined satisfaction-based components' relationships. The effective response rate was 91.4%. Several methods verified validity. Cronbach's alpha on internal reliability was above 0.902. On patient satisfaction, expectation scores are high: 6.50 (0.82), but perception scores are significantly lower 6.14 (1.02). Older patients' perception scores are lower than younger patients'. Expectation and perception scores for patients with different types of jobs are significantly different. Patients higher on education have lower scores for expectation (r = -0.09) and perception (r = -0.26). Factor analysis identified three factors in the 22 item SERVQUAL form, which account for 80.8% of the total variance for the expectation scores and 86.9% of the total variance for the satisfaction scores. Expectation and perception score gaps in all 22 items are significant. The goodness-of-fit summary of the SEM results indicates that expectations and perceptions are positively correlated, perceptions and loyalty are positively correlated, but expectations and loyalty are not positively correlated. The results of this research suggest that the SERVQUAL instrument is a useful measurement tool in assessing and monitoring service quality in kidney disease screening services, enabling the staff to identify where service improvements are needed from the patients' perspectives.

This study examined the predictive ability of educational background and demographic variables, available at the admission stage, to identify applicants who will graduate in 4 years from podiatric medical school. A logistic regression model was used to identify two predictors of 4-year graduation: age at matriculation and total Medical College Admission Test score. The model was cross-validated using a second independent sample from the same population. Cross-validation gives greater confidence that the results could be more generally applied. Total Medical College Admission Test score was the strongest predictor of 4-year graduation, with age at matriculation being a statistically significant but weaker predictor. Despite the model's capacity to predict 4-year graduation better than random assignment, a sufficient amount of error in prediction remained, suggesting that important predictors are missing from the model. Furthermore, the high rate of false-positives makes it inappropriate to use age and Medical College Admission Test score as admission screens in an attempt to eliminate attrition by not accepting at-risk students.

The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a commonly used tool in sports concussion assessment. While test-retest reliabilities have been established for the ImPACT cognitive composites, few studies have evaluated the psychometric properties of the ImPACT's Post-Concussion Symptom Scale (PCSS). The purpose of this study was to establish the test-retest reliability of symptom indices associated with the PCSS. Participants included 38 undergraduate students (50.0% male) who underwent neuropsychological testing as part of their participation in their psychology department's research subject pool. The majority of the participants were Caucasian (94.7%) and had no history of concussion (73.7%). All participants completed the ImPACT at two time points, approximately 6 weeks apart. The PCSS was the main outcome measure, and eight symptom indices were calculated (a total symptom score, three symptom summary indices, and four symptom clusters). Pearson correlations (r) and intraclass correlation coefficients (ICCs) were computed as measures of test-retest reliability. Overall, reliabilities ranged from low to high (r = .44 to .80; ICC = .44 to .77). The cognitive symptom cluster exhibited the highest test-retest reliability (r = .80, ICC = .77), followed by the positive symptom total (PST) index, an indicator of the total number of symptoms endorsed (r = .71, ICC = .69). In contrast, the commonly used total symptom score showed lower test-retest reliability (r = .67, ICC = .62). Paired-samples t tests revealed no significant differences between test and retest for any of the symptom variables (all p > .01). Finally, reliable change indices (RCI) were computed to determine whether differences observed between test and retest represented clinically significant change. RCI values were provided for each symptom index at the 80%, 90%, and 95% confidence intervals. These results suggest that evaluating additional symptom indices beyond the total symptom score from the PCSS is beneficial. Findings from this study can be applied to athlete samples to assess reliable change in symptoms following concussion.

Introducing Computer-Based Testing in High-Stakes Exams in Higher Education: Results of a Field Experiment.

2015-01-01

The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security) and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

Skill acquisition and maintenance requires spaced deliberate practice. Assessing medical students' physical examination performance ability is resource intensive. The authors assessed the nature and size of physical examination performance samples necessary to accurately estimate total physical examination skill. Physical examination assessment data were analyzed from second year students at the University of Illinois College of Medicine at Chicago in 2002, 2003, and 2004 (N = 548). Scores on subgroups of physical exam maneuvers were compared with scores on the total physical exam, to identify sound predictors of total test performance. Five exam subcomponents were sufficiently correlated to overall test performance and provided adequate sensitivity and specificity to serve as a means to prompt continued student review and rehearsal of physical examination technical skills. Selection and administration of samples of the total physical exam provide a resource-saving approach for promoting and estimating overall physical examination skills retention.

The dizziness handicap inventory (DHI) is widely used to evaluate self-perceived handicap due to dizziness, and is known to correlate with vestibular function tests in chronic dizziness. However, whether DHI reflects subjective symptoms during the acute phase has not been studied. This study aims to investigate the correlations of subjective and objective measurements to highlight parameters that reflect the severity of dizziness during the first week of acute unilateral vestibulopathy. Thirty-seven patients with acute unilateral vestibulopathy were examined. Patients' subjective perceptions of dizziness were measured using the DHI, Vertigo Visual Analog Scale (VVAS), Disability Scale (DS), and Activity-Specific Balance Scale (ABC). Additionally, the oculomotor tests, Romberg and sharpened Romberg tests, functional reach test, and dynamic visual acuity tests were performed. The correlation between the DHI and other tests was evaluated. DHI-total scores exhibited a moderately positive correlation with VVAS and DS, and a moderately negative correlation with ABC. However, DHI-total score did not correlate with results of the Romberg, sharpened Romberg, or functional reach tests. When compared among four groups divided according to DHI scores, VVAS and DS scores exhibited statistically significant differences, but no significant differences were detected for other test results. Our findings revealed that the DHI correlated significantly with self-perceived symptoms measured by VVAS and DS, but not ABC. There was no significant correlation with other balance function tests during the first week of acute vestibulopathy. The results suggest that DHI, VVAS and DS may be more useful to measure the severity of acute dizziness symptoms. Copyright © 2015 Elsevier Inc. All rights reserved.

This study examined the relationships between the Executive Function Performance Test (EFPT), the NIH Toolbox Cognitive Function tests, and neuropsychological executive function measures in 182 persons with traumatic brain injury (TBI) and 46 controls to evaluate construct, discriminant, and predictive validity. Construct validity: There were moderate correlations between the EFPT and the NIH Toolbox Crystallized (r = -.479), Fluid Tests (r = -.420), and Total Composite Scores (r = -.496). Discriminant validity: Significant differences were found in the EFPT total and sequence scores across control, complicated mild/moderate, and severe TBI groups. We found differences in the organisation score between control and severe, and between mild and severe TBI groups. Both TBI groups had significantly lower scores in safety and judgement than controls. Compared to the controls, the severe TBI group demonstrated significantly lower performance on all instrumental activities of daily living (IADL) tasks. Compared to the mild TBI group, the controls performed better on the medication task, the severe TBI group performed worse in the cooking and telephone tasks. Predictive validity: The EFPT predicted the self-perception of independence measured by the TBI-QOL (beta = -0.49, p < .001) for the severe TBI group. Overall, these data support the validity of the EFPT for use in individuals with TBI.

Association between home environment and the behavioral and neurocognitive development of children from a community childcare center for low-income families was examined (aged 6 to 12 years, n=155). The parents performed a questionnaire on home environment (K-HOME-Q) to assess home environment including parenting attitude and the Child Behavior Checklist (K-CBCL). The children performed the Wechsler Intelligence (IQ) Scale, Stroop interference test (Stroop), word fluency test (WF), and design fluency test (DF) to assess their neurocognitive development. 'Nurturing of Development' and 'Variety of Language Interaction' scores from the K-HOME-Q, were inversely associated with total behavior problems, externalization, rule-breaking, and aggressive behavior subscales of K-CBCL, and 'Emotional atmosphere' and 'Tolerance toward the child' scores showed inverse associations with the total behavior problems, rule-breaking, aggressive behavior, and withdrawn/depressed subscales. Despite economic hardship, the mean scores of the neurocognitive tests were comparable to the average level of Korean children's normative sample. However, 'Nurturing of Development' and 'Tolerance toward the Child' score of K-HOME-Q were associated with better executive function (IQ, WF, DF). These results suggest that parental stimulation of development and tolerant parenting attitude may offer protection against the negative effects of suboptimal economic environment on children's behavior and neurocognitive development.

Differences in testing modalities and cut-points used to define olfactory dysfunction contribute to the wide variability in estimating the prevalence of olfactory dysfunction in chronic rhinosinusitis (CRS). The aim of this study is to report the prevalence of olfactory impairment using each component of the Sniffin’ Sticks test (threshold, discrimination, identification, and total score) with age-adjusted and ideal cut-points from normative populations. Patients meeting diagnostic criteria for CRS were enrolled from rhinology clinics at a tertiary academic center. Olfaction was assessed using the Sniffin’ Sticks test. The study population consisted of 110 patients. The prevalence of normosmia, hyposmia, and anosmia using total Sniffin’ Sticks score was 41.8%, 20.0%, and 38.2% using age-appropriate cut-points and 20.9%, 40.9%, and 38.2% using ideal cut-points. Olfactory impairment estimates for each dimension mirrored these findings, with threshold yielding the highest values. Threshold, discrimination, and identification were also found to be significantly correlated to each other (P < 0.001). In addition, computed tomography scores, asthma, allergy, and diabetes were found to be associated with olfactory dysfunction. In conclusion, the prevalence of olfactory dysfunction is dependent upon olfactory dimension and if age-adjusted cut-points are used. The method of olfactory testing should be chosen based upon specific clinical and research goals. PMID:27469973

Administered the Bender-Gestalt (BG) and Minnesota Percepto-Diagnostic Test (MPD) to 69 first-grade children prior to administration of the California Achievement Test (CAT). Order of administration for the BG and MPD was counterbalanced to control for practice effects. Correlations (rs) were computed between the 9 CAT subtests and scores from the BG and MPD. The DD score from the MPD correlated significantly with all 9 CAT subtests. The SpCD score from the MPD correlated significantly with 6 of the 9 CAT subtests. The BG Koppitz score correlated significantly with 6 of the 9 CAT subtests. Both the DD and SpCD scores showed a significantly higher negative r with Reading Vocabulary, Total Reading, and Arithmetic Computation than the BG. Furthermore, both types of MPD scores showed a much higher average r with the 9 CAT subtests than was evident for the BG. These findings suggest that DD and SpCD scores from the MPD provide a more sensitive measure of deficits in visual-motor perception than the Koppitz score from the BG.

After 7 years, a group of originally nonemployed poverty-level older people (over 60) who had been employed as foster grandparents were retested with the WAIS. Four WAIS subtests - Vocabulary Similarities, Digit Span, and Block Design - were employed. Of the original group of 39, complete data were available for 28; 18 of these were still working on the project, and the other 10 had dropped out. Dropouts as a group tested lower originally and also showed more deterioration in functional health ratings over time. For the total group of 32 foster grandparents, three subtest scores showed stability over the 7 years. Only Digit Span showed a statistically significant drop. Neither age nor the initial level of health or WAIS scores was related to test-score changes over time.

Introduction: Clinical reasoning is one of the most important skills in the process of training a medical student to become an efficient physician. Assessment of the reasoning skills in a medical school program is important to direct students’ learning. One of the tests for measuring the clinical reasoning ability is Clinical Reasoning Problems (CRPs). The major aim of this study is to measure psychometric qualities of CRPs and define correlation between this test and routine MCQ in cardiology department of Shiraz medical school. Methods: This study was a descriptive study conducted on total cardiology residents of Shiraz Medical School. The study population consists of 40 residents in 2014. The routine CRPs and the MCQ tests was designed based on similar objectives and were carried out simultaneously. Reliability, item difficulty, item discrimination, and correlation between each item and the total score of CRPs were all measured by Excel and SPSS software for checking psycometeric CRPs test. Furthermore, we calculated the correlation between CRPs test and MCQ test. The mean differences of CRPs test score between residents’ academic year [second, third and fourth year] were also evaluated by Analysis of variances test (One Way ANOVA) using SPSS software (version 20)(α=0.05). Results: The mean and standard deviation of score in CRPs was 10.19 ±3.39 out of 20; in MCQ, it was 13.15±3.81 out of 20. Item difficulty was in the range of 0.27-0.72; item discrimination was 0.30-0.75 with question No.3 being the exception (that was 0.24). The correlation between each item and the total score of CRP was 0.26-0.87; the correlation between CRPs test and MCQ test was 0.68 (p<0.001). The reliability of the CRPs was 0.72 as calculated by using Cronbach's alpha. The mean score of CRPs was different among residents based on their academic year and this difference was statistically significant (p<0.001). Conclusion: The results of this present investigation revealed that CRPs could be reliable test for measuring clinical reasoning in residents. It can be included in cardiology residency assessment programs. PMID:29344528

Appropriate instructional design plays a crucial role in e-learning success, and analyzing learners is the cornerstone for instructional design process. Students' readiness for e-learning was assessed in the present study as an example of learner analysis for a distance course in medical education master program. A census sample of 23 students applied for distance master program on medical education, completed the "Students' E-Learning Readiness Scale" developed by Watkins, via email. The reliability and validity of the scale has been confirmed before. Average scores in total and 6 subscales were calculated. The score range was 1-5 and scores above 3 indicated good readiness. Data was interpreted using descriptive and non-parametric tests (Mann-Whitney U and Kruskal-Wallis). Response rate was 100%. The students' readiness scores in total and all subscales ("technology access", "online skills and relationships", "motivation", "online audio/video", "readiness for online discussions", and "importance of e-learning to your success") were above 3. Comparing different subscales, students' mean scores in "motivation" and "internet discussion" subscales were less than others, although the difference was not significant. There were no significant gender differences in the readiness scores. Students who were academic staff had significantly higher scores than others in total and in "motivation" and "online skills and relationship" subscales. Good learners' readiness, observed in the present study, may imply that the instructional designer can rely on e-learning strategies and build the course upon them. However, according to the slightly lower scores in "motivation" and "online discussion" subscales, it is recommended to stress more on strategies that improve these two components. To generalize the results, it is needed to test students' readiness in more different degree programs.

We present the initial validation of a two-factor structure of Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) using ImPACT composite scores and document the reliability and validity of this factor structure. Factor analyses were conducted for baseline (N = 21,537) and post-concussion (N = 560) data, yielding "Memory" (Verbal and Visual) and "Speed" (Visual Motor Speed and Reaction Time) Factors; inclusion of Total Symptom Scores resulted in a third discrete factor. Speed and Memory z-scores were calculated, and test-retest reliability (using intra-class correlation coefficients) at 1 month (0.88/0.81), 1 year (0.85/0.75), and 2 years (0.76/0.74) were higher than published data using Composite scores. Speed and Memory scores yielded 89% sensitivity and 70% specificity, which was higher than composites (80%/62%) and comparable with subscales (91%/69%). This emergent two-factor structure has improved test-retest reliability with no loss of sensitivity/specificity and may improve understanding and interpretability of ImPACT test results.

To contribute normative data for the Fototest from neurological patients with no cognitive impairment, including disaggregated data on each domain of the test (naming, free recall, total recall, and naming fluency). We performed a cross-sectional study in which neurological patients with no cognitive impairment were tested with the Fototest; we recorded total and domain scores. We performed a descriptive study of the total and domain scores, with data disaggregated by sex, age (over/under 65 years), and level of education (primary education completed/not completed; further study completed). We included a sample of 1,055 patients, who were mainly women (57.1%), aged over 65 (60.6%), and had a low level of education (38.6% had not completed primary education). Sex, age, and level of education influence total Fototest score (34.6 ± 5.3; P 10 : 28; P 5 : 27) and naming (5,9±0,3; 6; 5), free recall (8.5 ± 2.2; 6; 4), total recall (10.0 ± 1.5; 8; 7), and naming fluency scores (18.7 ± 4.9; 13; 12). For total score, the multivariate analysis revealed values of 1.5 ± 0.3 (ß ± SE) for sex (female), -2.4 ± 0.3 for age (> 65), and -1.6 ± 0.4 and 3.3 ± 0.4 for incomplete primary education and completed post-primary education, respectively (completed primary study was used as a reference). We provide normative data for total and domain Fototest results for each of the groups defined according to sex, age, and level of education. We also provide a percentile distribution of scores. We hope that these normative data will translate into increases in efficiency in Fototest administration in the clinical setting. Copyright © 2018 Sociedad Española de Neurología.

Holocaust survivors report a much higher prevalence of osteoporosis and fracture in the hip joint compared to those who were not Holocaust survivors. To evaluate whether being a Holocaust survivor could affect the functional outcome of hip fracture in patients 64 years of age and older undergoing rehabilitation. A retrospective cohort study compromising 140 consecutive hip fracture patients was conducted in a geriatric and rehabilitation department of a university-affiliated hospital. Being a Holocaust survivor was based on registry data. Functional outcome was assessed by the Functional Independence Measure (FIM)TM at admission and discharge from the rehabilitation ward. Data were analyzed by t-test, chi-square test, and linear regression analysis. Total and motor FIM scores at admission (P = 0.004 and P = 0.006, respectively) and total and motor FIM gain scores at discharge (P = 0.008 and P = 0.004 respectively) were significantly higher in non-Holocaust survivors compared with Holocaust survivors. A linear regression analysis showed that being a Holocaust survivor was predictive of lower total FIM scores at discharge (β = -0.17, P = 0.004). Hip fracture in Holocaust survivors showed lower total, motor FIM and gain scores at discharge compared to non-Holocaust survivor patients. These results suggest that being a Holocaust survivor could adversely affect the rehabilitation outcome following fracture of the hip and internal fixation.

Cough is a prevalent symptom that impacts quality of life in COPD. The aim of this study was to assess the relationship between cough-specific quality of life, abdominal muscle endurance, fatigue, and depression in stable patients with COPD. Twenty-eight patients with COPD (mean age 60.6±8.7 years) referred for pulmonary rehabilitation participated in this cross-sectional study. Sit-ups test was used for assessing abdominal muscle endurance. Leicester Cough Questionnaire (LCQ) was used to evaluate symptom-specific quality of life. Fatigue perception was evaluated with Fatigue Impact Scale (FIS). Beck Depression Inventory (BDI) was used for assessing depression level. The LCQ total score was significantly associated with number of sit-ups; BDI score; FIS total; physical, cognitive, and psychosocial scores (P<0.05). Scores of the LCQ physical, social, and psychological domains were also significantly related with number of sit-ups, FIS total score, and BDI score (P<0.05). FIS total score and number of sit-ups explained 58% of the variance in LCQ total score (r=0.76, r (2)=0.577, F(2-20)=12.296, P<0.001). Chronic cough may adversely affect performance in daily life due to its negative effect on fatigue and decrease abdominal muscle endurance in patients with COPD. Decreased cough-related quality of life is related with increased level of depression in COPD patients. Effects of increased abdominal muscle endurance and decreased fatigue in COPD patients with chronic cough need further investigation.

Recent evidence suggests that combining individual imaging markers of cerebral small vessel disease (SVD) may more accurately reflect its overall burden and better correlate with clinical measures. We wished to establish the clinical relevance of the total SVD score in a memory clinic population by investigating the association with SVD score and cognitive performance, cortical atrophy, and structural network measures, after adjusting for amyloid-β burden. We included 243 patients with amnestic mild cognitive impairment (MCI), Alzheimer's disease dementia, subcortical vascular MCI, or subcortical vascular dementia. All underwent MR and [11C] PiB-PET scanning and had standardized cognitive testing. Multiple linear regression was used to evaluate the relationships between SVD score and cognition, cortical thickness, and structural network measures. Path analyses were performed to evaluate whether network disruption mediates the effects of SVD score on cortical thickness and cognition. Total SVD score was associated with the performance of frontal (β - 4.31, SE 2.09, p = 0.040) and visuospatial (β - 0.95, SE 0.44, p = 0.032) tasks, and with reduced cortical thickness in widespread brain regions. Total SVD score was negatively correlated with nodal efficiency, as well as changes in brain network organization, with evidence of reduced integration and increasing segregation. Path analyses showed that the associations between SVD score and frontal and visuospatial scores were partially mediated by decreases in their corresponding nodal efficiency and cortical thickness. Total SVD burden has clinical relevance in a memory clinic population and correlates with cognition, and cortical atrophy, as well as structural network disruption.

Some healthy athletes report high levels of baseline concussion symptoms, which may be attributable to several factors (eg, illness, personality, somaticizing). However, the role of baseline symptoms in outcomes after sport-related concussion (SRC) has not been empirically examined. To determine if athletes with high symptom scores at baseline performed worse than athletes without baseline symptoms on neurocognitive testing after SRC. Cohort study. High school and collegiate athletic programs. A total of 670 high school and collegiate athletes participated in the study. Participants were divided into groups with either no baseline symptoms (Postconcussion Symptom Scale [PCSS] score = 0, n = 247) or a high level of baseline symptoms (PCSS score > 18 [top 10% of sample], n = 68). Participants were evaluated at baseline and 2 to 7 days after SRC with the Immediate Post-concussion Assessment and Cognitive Test and PCSS. Outcome measures were Immediate Post-concussion Assessment and Cognitive Test composite scores (verbal memory, visual memory, visual motor processing speed, and reaction time) and total symptom score on the PCSS. The groups were compared using repeated-measures analyses of variance with Bonferroni correction to assess interactions between group and time for symptoms and neurocognitive impairment. The no-symptoms group represented 38% of the original sample, whereas the high-symptoms group represented 11% of the sample. The high-symptoms group experienced a larger decline from preinjury to postinjury than the no-symptoms group in verbal (P = .03) and visual memory (P = .05). However, total concussion-symptom scores increased from preinjury to postinjury for the no-symptoms group (P = .001) but remained stable for the high-symptoms group. Reported baseline symptoms may help identify athletes at risk for worse outcomes after SRC. Clinicians should examine baseline symptom levels to better identify patients for earlier referral and treatment for their injury. Additional investigation of baseline symptoms is warranted to help delineate the type and severity of premorbid symptoms.

We investigate whether responses on a Low Luminance Questionnaire (LLQ) in patients with a range of age-related macular degeneration (AMD) severity are associated with their performance on focal dark adaptation (DA) testing and with choroidal thickness. Cross-sectional, single-center, observational study. A total of 113 participants older than 50 years of age with a range of AMD severity. Participants answered the LLQ on the same day they underwent DA testing using a focal dark adaptometer measuring rod intercept time (RIT). We performed univariable and multivariable analyses of the LLQ scores and age, RIT, AMD severity, subfoveal choroidal thickness [SFCT], phakic status, and best-corrected visual acuity. The primary outcome of this study was the score on the 32-question LLQ. Each item in the LLQ is designated to 1 of 6 subscales describing functional problems in low luminance: driving, emotional distress, mobility, extreme lighting, peripheral vision, and general dim lighting. Scores were computed for each subscale, in addition to a weighted total mean score. Responses from 113 participants (mean age, 76.2±9.3 years; 58.4% were female) and 113 study eyes were analyzed. Univariable analysis demonstrated that lower scores on all LLQ subscales were correlated with prolonged DA testing (longer RIT) and decreased choroidal thickness. All associations were statistically significant except for the association of choroidal thickness and "peripheral vision." The strongest association was the LLQ subscale of driving with RIT (r =-0.97, P < 0.001). Multivariable analysis for each of the LLQ subscale outcomes, adjusted for age, included RIT, with total LLQ score, "driving," "extreme lighting," and "mobility" also including choroidal thickness. In all multivariable analyses, RIT had a stronger association than choroidal thickness. This cross-sectional analysis demonstrates associations of patient-reported functional deficits, as assessed on the LLQ, with both reduced DA and reduced choroidal thickness, in a population of older adults with varying degrees of AMD severity and good visual acuity in at least 1 eye. These analyses suggest that local functional measurements of DA testing (RIT) and choroidal thickness are associated with patient-reported functional deficits. Published by Elsevier Inc.

The pediatric voice handicap index (pVHI) has been developed to provide a better insight into the parents' perception of their child's voice related quality of life. The purpose of the present study was to validate the Dutch pVHI by evaluating its internal consistency and reliability. Furthermore, we determined the optimal cut-off point for a normal pVHI score. All items of the English pVHI were translated into Dutch. Parents of children in our dysphonic and control group were asked to fill out the questionnaire. For the test re-test analysis we used a different study group who filled out the pVHI twice as part of a large follow up study. Internal consistency was analyzed through Cronbach's α coefficient. The test-retest reliability was assessed by determining Pearson's correlation coefficient. Mann-Whitney test was used to compare the scores of the questionnaire of the control group with the dysphonic group. By calculating receiver operating characteristic (ROC) curves, sensitivity and specificity we were able to set a cut-off point. We obtained data from 122 asymptomatic children and from 79 dysphonic children. The scores of the questionnaire significantly differed between both groups. The internal consistency showed an overall Cronbach α coefficient of 0.96 and an excellent test-retest reliability of the total pVHI questionnaire with a Pearson's correlation coefficient of 0.90. A cut-off point for the total pVHI questionnaire was set at 7 points with a specificity of 85% and sensitivity of 100%. A cut-off point for the VAS score was set at 13 with a specificity of 93% and sensitivity of 97%. The Dutch pVHI is a valid and reliable tool for the assessment of children with voice problems. By setting a cut-off point for the score of the total pVHI questionnaire of 7 points and the VAS score of 13, the pVHI might be used as a screening tool to assess dysphonic complaints and the pVHI might be a useful and complementary tool to identify children with dysphonia.

Abstract Background: Neurosteroids are endogenous molecules synthesized de novo in brain, adrenals, and other tissues. They demonstrate pleiotropic actions that are highly relevant to the neurobiology of schizophrenia. Clozapine markedly elevates neurosteroids in rodent hippocampus, potentially contributing to its superior therapeutic efficacy. Clinical evidence from a randomized controlled trial (RCT) conducted in Singapore suggests that pregnenolone significantly enhances functional capacity (as demonstrated by improvements in the UPSA Total Score and UPSA Communication Subscale Score) and that neurosteroid changes posttreatment predict therapeutic response (Marx et al 2014; Psychopharmacology). We thus conducted an RCT investigating adjunctive pregnenolone in schizophrenia. Methods: After a 2-week placebo lead-in, 88 participants with schizophrenia were randomized to pregnenolone (n = 42) or placebo (n = 46) for 8 weeks. Neurosteroids were quantified at baseline and posttreatment by mass spectrometry. Functional end points included the UPSA Total Score and UPSA Communication Subscale. Cognitive end points included the MCCB Composite Score and MCCB Subscales. Modified intent-to-treat analyses were conducted. Results: Participants randomized to the pregnenolone group did not outperform placebo on the UPSA Total Score or MCCB Composite Score. However, the pregnenolone group demonstrated significantly greater improvement in the UPSA Communication Subscale compared to participants randomized to placebo (P = .034), replicating prior RCT findings from Singapore. Elevations in pregnenolone post-treatment also predicted improvements in UPSA Total Score (r = .373; P = .039), again replicating prior efforts. In addition, the pregnenolone group demonstrated significantly greater improvement in the MCCB Verbal Learning Subscale compared to placebo (P = .023). Pregnenolone did not outperform placebo in the BACS Composite Score, SANS Total Score, or PANSS Total Score. Pregnenolone was well tolerated. Conclusion: Treatment with pregnenolone appears to improve functional capacity in a US population with schizophrenia, as assessed by the UPSA Communication Subscale and also supported by a significant positive correlation between pregnenolone changes and UPSA Total Score improvements—thus replicating findings from a prior RCT conducted in Singapore. Pregnenolone may also improve verbal memory. Given the positive correlation between pregnenolone increases posttreatment and UPSA Total Score improvements, it is possible that higher doses of pregnenolone may be clinically efficacious, and that neurosteroid quantification has biomarker potential for the predication of therapeutic response. Additional dose-finding investigations will be required to test these hypotheses. A pregnenolone decanoate formulation is currently in preclinical development.

The Brief Visuospatial Memory Test - Revised (BVMTR) and the Symbol Digit Modalities Test (SDMT) oral-only administration are known to be sensitive to cerebral disease in adult samples, but pediatric norms are not available. A demographically balanced sample of healthy control children (N = 92) ages 6-17 was tested with the BVMTR and SDMT. Multiple regression analysis (MRA) was used to develop demographically controlled normative equations. This analysis provided equations that were then used to construct demographically adjusted z-scores for the BVMTR Trial 1, Trial 2, Trial 3, Total Learning, and Delayed Recall indices, as well as the SDMT total correct score. To demonstrate the utility of this approach, a comparison group of children with acute disseminated encephalomyelitis (ADEM) or multiple sclerosis (MS) were also assessed. We find that these visual processing tests discriminate neurological patients from controls. As the tests are validated in adult multiple sclerosis, they are likely to be useful in monitoring pediatric onset multiple sclerosis patients as they transition into adulthood.

The functional performance of currently available body-powered prostheses is unknown. The goal of this study was to objectively assess and compare the functional performance of three commonly used body-powered upper limb terminal devices. Experimental trial. A total of 21 able-bodied subjects (n = 21, age = 22 ± 2) tested three different terminal devices: TRS voluntary closing Hook Grip 2S, Otto Bock voluntary opening hand and Hosmer Model 5XA hook, using a prosthesis simulator. All subjects used each terminal device nine times in two functional tests: the Nine-Hole Peg Test and the Box and Blocks Test. Significant differences were found between the different terminal devices and their scores on the Nine-Hole Peg Test and the Box and Blocks Test. The Hosmer hook scored best in both tests. The TRS Hook Grip 2S scored second best. The Otto Bock hand showed the lowest scores. This study is a first step in the comparison of functional performances of body-powered prostheses. The data can be used as a reference value, to assess the performance of a terminal device or an amputee. The measured scores enable the comparison of the performance of a prosthesis user and his or her terminal device relative to standard scores. © The International Society for Prosthetics and Orthotics 2014.

Outcomes after ventral incisional hernia (VIH) repair are measured by recurrence rate and subjective measures. No objective metrics evaluate functional outcomes after abdominal wall reconstruction. This study aimed to develop testing of abdominal wall strength (AWS) that could be validated as a useful metric. Data were prospectively collected during 9 months from 35 patients. A total of 10 patients were evaluated before and after VIH repair, for a total of 45 encounters. The patients were tested simultaneously or in succession by two of three examiners. Data were collected for three tests: double leg lowering (DLL), trunk raising (TR), and supine reaching (SR). Raw data were compared and tested for validity, and continuous data were transformed to categorical data. Agreement was measured using the intraclass correlation coefficient (ICC) for DLL and using kappa for the ordinal measures. Simultaneous testing yielded the following interobserver reliability: DLL (0.96 and 0.87), TR (1.00 and 0.95), and SR (0.76). Reproducibility was assessed by consecutive tests, with correlation as follows: DLL (0.81), TR (0.81), and RCH (0.21). Due to poor interobserver reliability for the SR test compared with the DLL and TR tests, the SR test was excluded from calculation of an overall score. Based on raw data distribution from the DLL and TR tests, the DLL data were categorized into 10º increments, allowing construction of a 10-point score. The median AWS score was 5 (interquartile range [IQR], 4-7), and there was agreement within 1 point for 42 of the 45 encounters (93%). The findings from this study demonstrate that the 10-point AWS score may measure AWS in an accurate and reproducible fashion, with potential for objective description of abdominal wall function of VIH patients. This score may help to identify patients suited for abdominal wall reconstruction while measuring progress after VIH repair. Further longitudinal outcomes studies are needed.

The Achilles tendon Total Rupture Score (ATRS), which is originally developed in 2007 in Swedish, is the only patient-reported outcome measure (PROM) for specific outcome assessment of an Achilles tendon rupture.Purpose of this study is to translate and cross-culturally adapt Achilles tendon Total Rupture Score (ATRS) into simplified Chinese, and primarily evaluate the responsiveness, reliability and validity. International recognized guideline which was designed by Beaton was followed to make the translation of ATRS from English into simplified Chinese version (CH-ATRS). A prospective cohort study was carried out for the cross-cultural adaptation. There were 112 participants included into the study. Psychometric properties including floor and ceiling effects, Cronbach's alpha, intraclass correlation coefficient, effect size, standard response mean, and construct validity were tested. The mean scores of CH-ATRS are 57.42 ± 13.70. No sign of floor or ceiling effect was found of CH-ATRS. High level of internal consistency was supported by the value of Cronbach's alpha (0.893). ICC (0.979, 95%CI: 0.984-0.993) was high to indicate the high test-retest reliability. Great responsive ness was proved with the high absolute value of ES and SRM (0.84 and 8.98, respectively). The total CH-ATRS score had very good correlation with physical function and body pain subscales of SF-36 (r = -0.758 and r = -0.694, respectively, p < 0.001), while poor correlation with vitality and role physical subscales of SF-36 (r = -0.033 and r = -0.025, respectively, p ≥ 0.05), which supported construct validity of CH-ATRS. This Chinese version of Achilles tendon Total Rupture Score (CH-ATRS) can be used as a reliable and valid instrument for Achilles tendon rupture assessing in Chinese-speaking population.

Individuals with attention deficit/hyperactivity disorder (ADHD) may suffer from emotional dysregulation (ED), although this symptom is not listed among the diagnostic criteria. Methylphenidate (MPH) is useful in reducing emotional symptoms in ADHD. The aim of the present study was to determine both psychosocial risk factors and presence of ED in adolescents with ADHD before and after MPH treatment. Eighty-two patients aged 12-18 years with ADHD were included as participants. The Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children - Present and Lifetime, the Difficulties in Emotion Regulation Scale (DERS), sociodemographic form, and the Inventory of Statements About Self-Injury were administered. Results were compared before and after 6 months MPH treatment. A significant improvement was detected on DERS for impulsivity (15.9±6.8 initial vs 14.2±6.5 final test, p <0.01) and total score (88.4±23.3 initial vs 82.4±2.7 final test, p <0.05) across all patients taking MPH regardless of subtype and sex. Despite treatment, a significant difference remained for impulsivity, strategies, and total score in patients with comorbid oppositional defiant disorder (ODD) compared with those without ODD, but no difference was detected for conduct disorder comorbidity. In patients who self-harm, scores for goals, impulsivity, strategies, clarity, and total score were higher before treatment: furthermore, impulsivity and total score remained high after treatment. In maltreated patients, goals, impulsivity, strategies, and total scores were significantly higher before treatment; however, their symptoms were ameliorated after treatment with MPH. Individuals with severe ED may "self-medicate" by smoking and/or self-harming. MPH led to significant improvements in ED possibly owing, in part, to a decrease in impulsivity, so that individuals felt more able to supervise their emotions and engage in goal-directed behaviors. ED should be considered particularly in patients with additional psychosocial factors and ODD comorbidity, and included in the treatment plan.

Stroke research and rehabilitation have traditionally focused on the physical and functional impact of a stroke. Less attention has been given to the psychosocial factors associated with this chronic condition. By the few studies that have specifically focused on psychosocial factors in the context of stroke, poststroke depression is demonstrated to significantly influence stroke outcomes. Associations of stroke with psychological symptoms other than depression have rarely been evaluated. This study was aimed to investigate the changes of psychological stress, social support and medication adherence in patients with ischemic stroke in the mainland of China. In this study, 90 patients with hemiplegia one year after first-ever middle cerebral artery infarction (stroke group) in the Zhongnan Hospital of Wuhan University from June 2008 to June 2011 were recruited for interview. Ninety age- and sex-matched normal volunteers (control group) were also examined at the same period. The psychological distress was assessed by the Symptom Checklist 90 (SCL-90), the social support by the Social Support Rating Scale (SSRS), and medication adherence by Morisky's self-reported inventory, respectively. Group differences were analyzed using unpaired-t test and chi-squared test. The results showed that total mean scores of the SCL-90 in the stroke group were higher than those in the control group (P<0.01). Except two dimensions, paranoid ideation and psychoticism, mean scores of the rest dimensions (including somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety) of SCL-90 were significantly higher in the stroke group than those in the control group (P<0.05, or P<0.01). The objective support, subjective support, support availability and total social support scores in the stroke group were significantly higher than those in the control group (P<0.05, or P<0.01). Those in the "SCL-90 total scores >150 group" were significantly higher than in the "SCL-90 total scores <100 group" and the "SCL-90 total scores between 100 to 150 group" (P<0.05, or P<0.01). Those in the "SCL-90 total scores between 100 to 150 group" were significantly higher than in the "SCL-90 total scores <100 group" (P<0.05). In 90 patients with ischemic stroke, 26 (28.89%) patients obtained high medication adherence, 47 (52.22%) patients medium medication adherence, and 17 (18.89%) patients low medication adherence, respectively. Among these stroke patients, there were 17 (50.00%) patients with high medication adherence in the "SCL-90 total scores >150 group", 28 (75.67%) patients with medium medication adherence in the "SCL-90 total scores between 100 to 150 group", and 12 (61.16%) patients with low medication adherence in the "SCL-90 total scores <100 group", respectively. There was significant difference in the medication adherence rate among the different SCL-90 scores groups in these stroke patients (P<0.05 or P<0.01). It was led to conclude that ischemic stroke patients one year after hemiplegia have psychological distress, low level of social support and poor medication adherence in the mainland of China. Therefore, it is necessary to mobilize the government, medical institutions and various social support groups to offer psychological interventions to relieve the stress of patients with ischemic stroke, and improve their medication adherence.

To evaluate the effectiveness of a Web-based course on infection control accessed by physicians in training. Educational intervention. A 607-bed urban teaching hospital. A total of 55 physicians in training beginning their first postgraduate year (the iPGY1 group) and 59 physicians completing their first, second, or third postgraduate year (the oPGY group). Individuals in the iPGY1 group took a Web-based course on infection control practices. Persons in the iPGY1 group who took the Web-based course completed an evaluation test consisting of 15 multiple-choice questions (total possible score, 15 points). The same test was given to persons in the oPGY group, who did not take the Web-based course. We compared scores of the Web-based test taken by subjects in the iPGY1 group immediately after the course with scores of the test they took 3 months after the course and with test scores of subjects in the oPGY group. The mean score (+/-SD) for subjects in the iPGY1 group who took the Web-based course was 10.6+/-2.2, compared with 8.0+/-2.5 for subjects in the oPGY group (P<.001). The mean score (+/-SD) for subjects in the iPGY1 group 3 months after completing the course decreased to 8.0+/-2.4 (P<.001 by the paired t test). For the oPGY group, significant differences were found between the scores (+/-SD) for subjects in the internal medicine (9.9+/-2.3), emergency medicine (8.4+/-1.7), pediatrics (7.0+/-1.7), and family medicine (5.8+/-1.6) residency programs (P<.001); there were no significant differences in scores according to the year of residency. Web-based infection control courses are an attractive teaching tool for physicians in training and need to be considered for teaching infection control. The evaluation of information retention will help identify physicians in training who require further training.

This study investigates the test-retest reliability of a battery of executive function (EF) tasks with a specific interest in testing whether the method that is used to create a battery-wide score would result in differences in the apparent test-retest reliability of children's performance. A total of 188 4-year-olds completed a battery of computerized EF tasks twice across a period of approximately two weeks. Two different approaches were used to create a score that indexed children's overall performance on the battery-i.e., (1) the mean score of all completed tasks and (2) a factor score estimate which used confirmatory factor analysis (CFA). Pearson and intra-class correlations were used to investigate the test-retest reliability of individual EF tasks, as well as an overall battery score. Consistent with previous studies, the test-retest reliability of individual tasks was modest (rs ≈ .60). The test-retest reliability of the overall battery scores differed depending on the scoring approach (r mean  = .72; r factor_ score  = .99). It is concluded that the children's performance on individual EF tasks exhibit modest levels of test-retest reliability. This underscores the importance of administering multiple tasks and aggregating performance across these tasks in order to improve precision of measurement. However, the specific strategy that is used has a large impact on the apparent test-retest reliability of the overall score. These results replicate our earlier findings and provide additional cautionary evidence against the routine use of factor analytic approaches for representing individual performance across a battery of EF tasks.

Type 2 diabetes markedly increases the risk of coronary heart disease (CHD), and screening for CHD is suggested by the guidelines. The aim of the study was to compare the diagnostic usefulness of the simple exercise test score, incorporating the clinical data and cardiac stress test results, with the standard stress test in patients with type 2 diabetes. A total of 62 consecutive patients (aged 65.4 ±8.5 years; 32 men) with type 2 diabetes and clinical symptoms suggesting CHD underwent a stress test followed by coronary angiography. The simple score was calculated for all patients. Significant coronary stenosis was observed in 41 patients (66.1%). Stress test results were positive in 36 patients (58.1%). The mean simple score was high (65.5 ±14.3 points). A positive linear relationship was observed between the score and the prevalence of CHD (R2 = 0.19; P <0.001) as well as its severity (R² = 0.23; P <0.001). The area under the receiver-operating characteristic curve for the simple score was 0.74 (95% confidence interval [CI], 0.62-0.86). At the original cut-off value of 60 points, the score had a similar prognostic value to that of the standard stress test. However, in a multivariate analysis, only the simple score (odds ratio [OR], 1.46; 95% CI, 1.11-1.94; P <0.01 for an increase in the score by 1 point) and male sex (OR, 1.57; 95% CI, 1.24-1.98; P <0.001) remained independent predictors of CHD. In patients with type 2 diabetes, the simple score correlated with the prevalence and severity of CHD. However, the cut-off value of 60 points was inadequate in the population of diabetic patients with high risk of CHD. The simple score used instead of or together with the stress test was a better predictor of CHD than the stress test alone.

Verbal reasoning is a complex, multicomponent function, which involves activation of functional processes and neural circuits distributed in both brain hemispheres. Thus, this ability is often impaired after brain injury. The aim of the present study is to describe the construction of a new verbal reasoning test (VRT) for patients with brain injury and to provide normative values in a sample of healthy Italian participants. Three hundred and eighty healthy Italian subjects (193 women and 187 men) of different ages (range 16-75 years) and educational level (primary school to postgraduate degree) underwent the VRT. VRT is composed of seven subtests, investigating seven different domains. Multiple linear regression analysis revealed a significant effect of age and education on the participants' performance in terms of both VRT total score and all seven subtest scores. No gender effect was found. A correction grid for raw scores was built from the linear equation derived from the scores. Inferential cut-off scores were estimated using a non-parametric technique, and equivalent scores were computed. We also provided a grid for the correction of results by z scores.

This study investigated the validity of three American College Testing-Proficiency Examination Program (ACT-PEP) tests (Maternal and Child Nursing, Psychiatric/Mental Health Nursing, Adult Nursing) for predicting the academic performance of registered nurses (RNs) enrolled in bachelor's degree BSN programs nationwide. This study also examined RN students' performance on the ACT-PEP tests by their demographic characteristics: student's age, sex, race, student status (full- or part-time), and employment status (full- or part-time). The total sample for the three tests comprised 2,600 students from eight institutions nationwide. The median correlation coefficients between the three ACT-PEP tests and the semester grade point averages ranged from .36 to .56. Median correlation coefficients increased over time, supporting the stability of ACT-PEP test scores for predicting academic performance over time. The relative importance of selected independent variables for predicting academic performance was also examined; the most important variable for predicting academic performance was typically the ACT-PEP test score. Across the institutions, student demographic characteristics did not contribute significantly to explaining academic performance, over and above ACT-PEP scores.

Heparin-induced thrombocytopenia (HIT) should be diagnosed clinically as well as by laboratory assays for timely recognition, prevention and management of complications. To evaluate the clinical utility of pre-test clinical scoring system in combination with two immunoassays for the diagnosis of HIT in cardiac surgery patients. A total of 100 consecutive patients undergoing cardiac surgery were studied. Pre-test clinical scoring was carried out in patients with thrombocytopenia and further tested by two immunoassays, i.e., Heparin platelet factor 4 (H-PF4) enzyme-linked immunosorbent assay (ELISA) and particle gel immunoassay (PaGIA). Of the 100 patients studied, 42 patients developed thrombocytopenia post-operatively. On pre-test clinical scoring, low T-score was observed in 6 patients, intermediate in 28 and high score in 8 patients, whereas 19 patients (45.2%) were positive by H-PF4 ELISA and 10 (23.8%) by PaGIA for H-PF4 antibody. The difference in the incidence of clinically significant HIT antibodies in the three categories was statistically significant. A good correlation was also observed with ELISA optical density, T-scoring and PaGIA. Pre-test clinical scoring correlates well with the development of H-PF4 antibodies which are incriminated in the causation of thrombotic complications in patients with HIT. We also propose a protocol for diagnosing patients with clinical suspicion of HIT using pre-test clinical scoring and immunoassay. © 2011 The Authors.

This study documented baseline neurocognitive performance of 23,815 athletes on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) test. Specifically, 9,733 Hispanic, Spanish-speaking athletes who completed the ImPACT test in English and 2,087 Hispanic, Spanish-speaking athletes who completed the test in Spanish were compared with 11,955 English-speaking athletes who completed the test in English. Athletes were assigned to age groups (13-15, 16-18). Results revealed a significant effect of language group (p < .001; partial η(2) = 0.06) and age (p < .001; partial η(2) = 0.01) on test performance. Younger athletes performed more poorly than older athletes, and Spanish-speaking athletes completing the test in Spanish scored more poorly than Spanish-speaking and English-speaking athletes completing the test in English, on all Composite scores and Total Symptom scores. Spanish-speaking athletes completing the test in English also performed more poorly than English-speaking athletes completing the test in English on three Composite scores. These differences in performance and reported symptoms highlight the need for caution in interpreting ImPACT test data for Hispanic Americans.

Advanced hepatocellular carcinoma (HCC) is associated with various clinical conditions including major vessel invasion, metastasis, and poor performance status. The aim of this study was to establish a prognostic scoring system and to propose a sub-classification of the Barcelona-Clinic Liver Cancer (BCLC) stage C. This retrospective study included consecutive patientswho received sorafenib for BCLC stage C HCC at a single tertiary hospital in Korea. A Cox proportional hazard model was used to develop a scoring system, and internal validationwas performed by a 5-fold cross-validation. The performance of the model in predicting risk was assessed by the area under the curve and the Hosmer-Lemeshow test. A total of 612 BCLC stage C HCC patients were sub- classified into strata depending on their performance status. Five independent prognostic factors (Child-Pugh score, α-fetoprotein, tumor type, extrahepatic metastasis, and portal vein invasion) were identified and used in the prognostic scoring system. This scoring system showed good discrimination (area under the receiver operating characteristic curve, 0.734 to 0.818) and calibration functions (both p < 0.05 by the Hosmer-Lemeshow test at 1 month and 12 months, respectively). The differences in survival among the different risk groups classified by the total score were significant (p < 0.001 by the log-rank test in both the Eastern Cooperative Oncology Group 0 and 1 strata). The heterogeneity of patientswith BCLC stage C HCC requires sub-classification of advanced HCC. A prognostic scoring system with five independent factors is useful in predicting the survival of patients with BCLC stage C HCC.

Cross sectional. This study presents the factor analysis of the Spinal Appearance Questionnaire (SAQ) and its psychometric properties. Although the SAQ has been administered to a large sample of patients with adolescent idiopathic scoliosis (AIS) treated surgically, its psychometric properties have not been fully evaluated. This study presents the factor analysis and scoring of the SAQ and evaluates its psychometric properties. The SAQ and the Scoliosis Research Society-22 (SRS-22) were administered to AIS patients who were being observed, braced or scheduled for surgery. Standard demographic data and radiographic measures including Lenke type and curve magnitude were also collected. Of the 1802 patients, 83% were female; with a mean age of 14.8 years and mean initial Cobb angle of 55.8° (range, 0°-123°). From the 32 items of the SAQ, 15 loaded on two factors with consistent and significant correlations across all Lenke types. There is an Appearance (items 1-10) and an Expectations factor (items 12-15). Responses are summed giving a range of 5 to 50 for the Appearance domain and 5 to 20 for the Expectations domain. The Cronbach's α was 0.88 for both domains and Total score with a test-retest reliability of 0.81 for Appearance and 0.91 for Expectations. Correlations with major curve magnitude were higher for the SAQ Appearance and SAQ Total scores compared to correlations between the SRS Appearance and SRS Total scores. The SAQ and SRS-22 Scores were statistically significantly different in patients who were scheduled for surgery compared to those who were observed or braced. The SAQ is a valid measure of self-image in patients with AIS with greater correlation to curve magnitude than SRS Appearance and Total score. It also discriminates between patients who require surgery from those who do not.

We sought to compare measurements of circulating cell-free DNA as well as Down syndrome test results in women with naturally conceived pregnancies with those conceived using assisted reproductive technologies. Data regarding assisted reproductive technologies were readily available from seven enrollment sites participating in an external clinical validation trial of nested case/control design. Measurements of circulating cell-free fetal and total DNA, fetal fraction (ratio of fetal to total DNA), chromosome-specific z-scores, and karyotype results were available for analysis. Analyses were restricted to 632 euploid (5.2% assisted reproductive technologies) and 73 Down syndrome (13.7% assisted reproductive technologies), including 16 twin pregnancies. No differences were found for fetal or total circulating cell-free DNA, or for the fetal fraction in euploid (P = 0.70) or Down syndrome (P = 0.58) pregnancies by method of conception. There appeared to be systematic z-score reductions for chromosomes 21, 18, and 13 in assisted reproductive technologies versus natural euploid pregnancies (P = 0.048, 0.0032, and 0.36, respectively). Assisted reproductive technologies and naturally conceived pregnancies contribute similar levels of circulating cell-free DNA into maternal circulation. Small differences in the z-scores of pregnancies achieved by assisted reproductive technologies were observed and do not appear to be test-related artifacts. However, the findings need confirmation before any consideration of changes to testing and reporting protocols.

Objective: To evaluate the effect of information provided before surgery on the self-esteem and body image of women undergoing hysterectomy. Materials and Methods: The study had a semi-experimental design with pre-post tests. A total of 60 women were included in the study and divided into two groups, the intervention group (n=30) and control group (n=30). A questionnaire, the Rosenberg self-esteem scale, and the body image scale were used to collect data. Results: The pre- and post-test body image scores were similar in the intervention group patients, but the post-test scores were significantly higher in the control group (p<0.05). The pre- and post-test self-esteem scores were again similar in the intervention group, but the post-test scores were significantly lower in the control group (p<0.05). Conclusion: This study revealed that health education given to patients prior to hysterectomy protects body image and consequently self-esteem. PMID:28913071

Despite prevention strategies, hospital-acquired pressure ulcers (HAPUs) continue to occur in the acute care setting. The purpose of this study was to develop an operational definition of and an instrument for identifying avoidable/unavoidable HAPUs in the acute care setting. The Indiana University Health Pressure Ulcer Prevention Inventory (PUPI) was developed and psychometric testing was performed. A retrospective pilot study of 31 adult hospitalized patients with an HAPU was conducted using the PUPI. Overall content validity index of 0.99 and individual item content validity index scores (0.9-1.0) demonstrated excellent content validity. Acceptable PUPI criterion validity was demonstrated with no statistically significant differences between wound specialists' and other panel experts' scoring. Construct validity findings were acceptable with no statistically significant differences among avoidable or unavoidable HAPU patients and their Braden Scale total scores. Interrater reliability was acceptable with perfect agreement on the total PUPI score between raters (κ = 1.0; P = .025). Raters were in total agreement 93% (242/260) of the time on all 12 individual PUPI items. No risk factors were found to be significantly associated with unavoidable HAPUs. An operational definition of and an instrument for identifying avoidable/unavoidable HAPUs in the acute care setting were developed and tested. The instrument provides an objective and structured method for identifying avoidable/unavoidable HAPUs. The PUPI provides an additional method that could be used in root-cause analyses and when reporting adverse pressure ulcer events.

[Purpose] To examine if the SPPB is higher with healthy subjects than outpatients, which was higher than inpatients and if the SPPB can be validated assessment tool for strength tests and lower extremity morphological evaluation in cardiovascular disease patients. [Subjects and Methods] Twenty-four middle aged and older adults with cardiovascular disease were recruited from inpatient and outpatient facilities and assigned to separate experimental groups. Twelve age-matched healthy volunteers were assigned to a control group. SPPB test was used to assess balance and functional motilities. The test outcomes were compared with level of care (inpatient vs. outpatient), physical characteristics, strength and lower extremity morphology. [Results] Total SPPB scores, strength tests (knee extensor muscle strength), and lower extremity morphological evaluation (muscle thickness of anterior and posterior mid-thigh and posterior lower-leg) were greater in healthy subjects and outpatients groups compared with inpatients. To predict total Short Physical Performance Battery scores, the predicted knee extension and anterior mid-thigh muscle thickness were calculated. [Conclusion] The SPPB is an effective tool as the strength tests and lower extremity morphological evaluation for middle-aged and older adult cardiovascular disease patients. Notably, high knee extensor muscle strength and quadriceps femoris muscle thickness are positively associated with high SPPB scores.

Fundamentals of Laparoscopic Surgery (FLS) certification testing currently is offered at accredited test centers or at select surgical conferences. Maintaining these test centers requires considerable investment in human and financial resources. Additionally, it can be challenging for individuals outside North America to become FLS certified. The objective of this pilot study was to assess the feasibility of remotely administering and scoring the FLS examination using live videoconferencing compared with standard onsite testing. This parallel mixed-methods study used both FLS scoring data and participant feedback to determine the barriers to feasibility of remote proctoring for the FLS examination. Participants were tested at two accredited FLS testing centers. An official FLS proctor administered and scored the FLS exam remotely while another onsite proctor provided a live score of participants' performance. Participant feedback was collected during testing. Interrater reliabilities of onsite and remote FLS scoring data were compared using intraclass correlation coefficients (ICCs). Participant feedback was analyzed using modified grounded theory to identify themes for barriers to feasibility. The scores of the remote and onsite proctors showed excellent interrater reliability in the total FLS (ICC 0.995, CI [0.985-0.998]). Several barriers led to critical errors in remote scoring, but most were accompanied by a solution incorporated into the study protocol. The most common barrier was the chain of custody for exam accessories. The results of this pilot study suggest that remote administration of the FLS has the potential to decrease costs without altering test-taker scores or exam validity. Further research is required to validate protocols for remote and onsite proctors and to direct execution of these protocols in a controlled environment identical to current FLS test administration.

Disentangling Gratitude: A Theoretical and Psychometric Examination of the Gratitude Resentment and Appreciation Test-Revised Short (GRAT-RS).

Hammer, Joseph H; Brenner, Rachel E

2017-07-14

This study extended our theoretical and applied understanding of gratitude through a psychometric examination of the most popular multidimensional measure of gratitude, the Gratitude, Resentment, and Appreciation Test-Revised Short form (GRAT-RS). Namely, the dimensionality of the GRAT-RS, the model-based reliability of the GRAT-RS total score and 3 subscale scores, and the incremental evidence of validity for its latent factors were assessed. Dimensionality measures (e.g., explained common variance) and confirmatory factor analysis results with 426 community adults indicated that the GRAT-RS conformed to a multidimensional (bifactor) structure. Model-based reliability measures (e.g., omega hierarchical) provided support for the future use of the Lack of a Sense of Deprivation raw subscale score, but not for the raw GRAT-RS total score, Simple Appreciation subscale score, or Appreciation of Others subscale score. Structural equation modeling results indicated that only the general gratitude factor and the lack of a sense of deprivation specific factor accounted for significant variance in life satisfaction, positive affect, and distress. These findings support the 3 pillars of gratitude conceptualization of gratitude over competing conceptualizations, the position that the specific forms of gratitude are theoretically distinct, and the argument that appreciation is distinct from the superordinate construct of gratitude.

To examine sex differences in vestibular and oculomotor symptoms and impairment in athletes with sport-related concussion (SRC). The secondary purpose was to replicate previously reported sex differences in total concussion symptoms, and performance on neurocognitive and balance testing. Prospective cross-sectional study of consecutively enrolled clinic patients within 21 days of a SRC. Specialty Concussion Clinic. Included male (n = 36) and female (n = 28) athletes ages 9 to 18 years. Vestibular symptoms and impairment was measured with the Vestibular/Ocular Motor Screening (VOMS). Participants completed the Immediate Post-concussion Assessment and Cognitive Test (ImPACT), Post-concussion Symptom Scale (PCSS), and Balance Error Scoring System (BESS). Sex differences on clinical measures. Females had higher PCSS scores (P = 0.01) and greater VOMS vestibular ocular reflex (VOR) score (P = 0.01) compared with males. There were no sex differences on BESS or ImPACT. Total PCSS scores together with female sex accounted for 45% of the variance in VOR scores. Findings suggest higher VOR scores after SRC in female compared with male athletes. Findings did not extend to other components of the VOMS tool suggesting that sex differences may be specific to certain types of vestibular impairment after SRC. Additional research on the clinical significance of the current findings is needed.

Medical schools use a variety of preadmission indices to select potential students. These indices generally include undergraduate grade point average (GPA), Medical College Admission Test (MCAT) scores, and preadmission interviews. To investigate whether the admission indices used by Midwestern University Arizona College of Osteopathic Medicine are associated with the academic and clinical performance of their students. Associations between the prematriculation variables of undergraduate science GPA, undergraduate total GPA, MCAT component scores, and interview scores and the academic and clinical variables of the first- and second-year medical school GPA, Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Cognitive Evaluation (CE) total and discipline scores, scores in clinical rotations for osteopathic competencies, COMLEX-USA Level 2-Performance Evaluation passage, and match status were evaluated. Two-tailed Pearson product-moment correlations with a Bonferroni adjustment were used to examine these relationships. The traditional predictors of science and total undergraduate GPA as well as total and component MCAT scores had small to moderate associations with first- and second-year GPA, as well as COMLEX-USA Level 1 and Level 2-CE total scores. Of all predictors, only the MCAT biological sciences score had a statistically significant correlation with failure of the COMLEX-USA Level 2-Performance Evaluation examination (P=.009). Average interview scores were associated only with the osteopathic competency of medical knowledge (r=0.233; n=209; P=.001), as assessed by clerkship preceptors. No predictors were associated with scores in objective structured clinical encounters or with failing to match to a residency position. The data indicate that traditional predictors of academic performance (undergraduate GPA, undergraduate science GPA, and MCAT scores) have small to moderate association with medical school grades and performance on COMLEX-USA Level 1 and Level 2-CE. This finding requires additional research into the value of the interview in the medical school admissions process and the availability of alternatives that allow better prediction and assessment of applicant performance.

BAKCKGROUND: Olfactory dysfunction is present in up to 90% of Parkinson's disease (PD) patients. It is usually evaluated by means of objective standardized tests; however no self-administered scales have been developed for olfactory dysfunction bedside assessment. We present validation of a new scale to assess this symptom in PD patients. Seventy-five PD patients and 25 control subjects were evaluated using a Hyposmia Rating Scale developed in-house, combined with the extended Sniffin' Sticks test. Total score of the 6-item Hyposmia Rating Scale showed significant correlation with threshold, discrimination, identification and total Sniffin' Sticks test scores (r = 0.53; r = 0.60; r = 0.57; r = 0.65 respectively, p < 0.001 for all values). Area under the curve of the receiver operating curve for the ability of Hyposmia Rating Scale to discriminate patients with Sniffin' Sticks test total scores below or above the cut-off point was 80 ± 6% (p < 0.001). Considering Sniffin' Sticks test as the gold standard method for olfactory dysfunction detection, an affirmative response to a single screening question about smelling ability problems showed 35% sensitivity (95%CI = 23-47%) and 100% specificity. The best cut-off point for Hyposmia Rating Scale was 22.5 with a sensitivity of 70% (60-81%) and a specificity of 85% (65-100%). The Hyposmia Rating Scale here presented may offer a simple, cost-effective, time-saving and reliable approach to evaluate olfactory dysfunction in PD patients. Copyright © 2011.

Aim Impaired illness insight may hamper treatment outcome in patients with alcohol-related cognitive deficits. In this study, a short questionnaire for the assessment of illness insight (eg, the Q8) was investigated in patients with Korsakoff’s syndrome (KS) and in alcohol use disorder (AUD) patients with mild neurocognitive deficits. Methods First, reliability coefficients were computed and internal structure was investigated. Then, comparisons were made between patients with KS and patients with AUD. Furthermore, correlations with the Dysexecutive Questionnaire (DEX) were investigated. Finally, Q8 total scores were correlated with neuropsychological tests for processing speed, memory, and executive function. Results Internal consistency of the Q8 was acceptable (ie, Cronbach’s α =0.73). The Q8 items represent one factor, and scores differ significantly between AUD and KS patients. The Q8 total score, related to the DEX discrepancy score and scores on neuropsychological tests as was hypothesized, indicates that a higher degree of illness insight is associated with a higher level of cognitive functioning. Conclusion The Q8 is a short, valid, and easy-to-administer questionnaire to reliably assess illness insight in patients with moderate-to-severe alcohol-related cognitive dysfunction. PMID:27445476

This study used a within-participant design to evaluate the concurrent validity and test-retest reliability of the Violent Ideations Scale in a general population, English-speaking opportunistic sample. Data from 116 adult participants ( M age = 33.7, SD = 11.9, male = 30 [25.9%]) were used to compare scores on the Violent Ideations Scale and Aggression Questionnaire and responses to the Schedule of Imagined Violence. A subgroup of 27 participants ( M age = 37.2, SD = 13.6, male = 8 [29.6%]) completed the Violent Ideations Scale on a second occasion, 2 weeks later. The Violent Ideations Scale was found to correlate significantly with the Aggression Questionnaire subscale and total scores, with the strongest correlations being with physical aggression and total scores. Participants were more likely to be categorized as having experienced a violent ideation based on responses to the Violent Ideation Scale, compared with the Schedule of Imagined Violence, most likely due to the Schedule of Imagined Violence underestimating the prevalence of violent ideation. A significant, strong correlation was found between total Violent Ideations Scale scores at Time 1 and Time 2. Overall, the Violent Ideations Scale was found to have concurrent validity when compared with the Aggression Questionnaire and good test-retest reliability, suggesting that it would be suitable for use with a nonclinical, English-speaking sample.

Aim: Our aim was to evaluate physicians’ attitudes toward pharmacogenetic testing before and after pharmacogenetic education. Methods: In total, 12 physicians (˜40% response rate) completed a survey with eight questions on 10-point scales on their attitudes toward pharmacogenetic testing before and after a 1-h grand rounds presentation on pharmacogenetics. Differences in question scores overall, among training levels (resident/fellow/attending), and specific drugs (clopidogrel/simvastatin/warfarin) were assessed using Wilcoxon signed-rank and exact Kruskal–Wallis tests. Results & conclusion: The scores for all eight questions increased, with statistically significant (p < 0.05) increases for four out of eight questions. The scores were similar among training levels, but the postscores for clopidogrel were significantly higher than for simvastatin and warfarin. In conclusion, brief pharmacogenetic education can significantly affect physicians’ attitudes toward pharmacogenetic testing. PMID:29749904

Background On March 11, 2011, Japan was struck by a massive earthquake and tsunami. The tsunami caused tremendous damage and traumatized several people, including children. The aim of this study was to assess changes in traumatic symptoms 8, 20, and 30 months of the 2011 tsunami. Methods The study comprised three groups. Copies of the Post-Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-rating questionnaire on traumatic symptoms, were distributed to 12,524 children (8-month period), 12,193 children (20-month period), and 11,819 children (30-month period). An effective response of children 8 months, 20 months, and 30 month after the disaster was obtained in 11,639 (92.9%), 10,597 (86.9%), and 10,812 children (91.4%), respectively. We calculated the total score, PTSD subscale, and Depression subscale of PTSSC-15. We calculated the total score, PTSD subscale, and Depression subscale of PTSSC-15. Results The PTSSC-15 total score and PTSD subscale of children belonging to 1st–9th grade groups who were tested 30 and 20 months after the tsunami significantly decreased compared with those of children tested 8 months after the tsunami. The PTSSC-15 total score and PTSD subscale of children in 1st–9th grade groups tested after 30 months did not decrease significantly compared with those of children tested after 20 months. The PTSSC-15 Depression subscale and PTSD subscale of children in 1st–9th grade groups tested after 30 months significantly decreased compared with those of children tested 8 months after the tsunami. The PTSSC-15 Depression subscale of children in 1st–9th grade groups evaluated after 30 months significantly decreased compared with those of children evaluated after 20 months. Conclusions This study demonstrates that the traumatic symptoms of children who survived the massive tsunami improved with time. Nonetheless, the traumatic symptoms, which in some cases did not improve with time. PMID:25340759

Non-motor symptoms are common in Parkinson's disease (PD), and are the primary cause of disability in many PD patients. Our aim in this study was to translate the origin non-motor symptoms scale for PD (NMSS), which was written in English, into Korean (K-NMSS), and to evaluate its reliability and validity for use with Korean-speaking patients with PD. In total, 102 patients with PD from 9 movement disorders sections of university teaching hospitals in Korea were enrolled in this study. They were assessed using the K-NMSS, the Unified Parkinson's Disease Rating Scale (UPDRS), the Korean version of the Mini-Mental Status Examination (K-MMSE), the Korean version of the Montgomery-Asberg Depression Rating Scale (K-MADS), the Epworth Sleepiness Scale (ESS), and Parkinson's Disease Questionnaire 39 (PDQ39). Test-retest reliability was assessed over a time interval of 10-14 days in all but one patient. The K-NMSS was administered to 102 patients with PD. The internal consistency and reliability of this tool was 0.742 (mean Cronbach's α-coefficient). The test-retest correlation reliability was 0.941 (Guttman split-half coefficient). There was a moderate correlation between the total K-NMSS score and the scores for UPDRS part I [Spearman's rank correlation coefficient, (rS)=0.521, p<0.001] and UPDRS part II (rS=0.464, p=0.001), but there was only a weak correlation between the total K-NMSS score and the UPDRS part III score (rS=0.288, p=0.003). The total K-NMSS score was significantly correlated with the K-MADS (rS=0.594, p<0.001), K-MMSE (rS=-0.291, p=0.003), and ESS (rS=0.348, p<0.001). The total K-NMSS score was also significantly and positively correlated with the PDQ39 score (rS=0.814, p<0.001). The K-NMSS exhibited good reliability and validity for the assessment of non-motor symptoms in Korean PD patients.

We aimed to evaluate the validity and reliability of the Infant Breastfeeding Assessment Tool (IBFAT), the Mother Baby Assessment (MBA) Tool, and the LATCH scoring system. Mothers who delivered healthy, full-term infants in the Obstetrics & Gynecology Service of Gazi University, Ankara, Turkey, between December 2013 and January 2014 and their infants were included in the study. Forty-six randomly selected breastfeeding sessions were monitored and scored simultaneously by three researchers (Raters 1, 2, and 3) using LATCH, IBFAT, and the MBA Tool. Researchers put the score sheets in an envelope in order to hide them from each other. The compatibility of the scores given by three researchers was assessed by statistical methods. We found positive and significant correlation coefficients between 0.81 to 0.88 for the total MBA score, between 0.90 to 0.95 for the total IBFAT score, and between 0.85 to 0.91 for the total LATCH score. Correlation coefficients testing these three tools ranged from 0.71 to 0.88, with the minimum value being noted for the correlation between LATCH and IBFAT scores and the maximum value being noted for the correlation between LATCH and MBA scores. We found positive and significant correlations between researchers' scores for 46 observations using the three assessment tools. This study showed that these above-mentioned tools were compatible for the assessment of the efficiency of breastfeeding.

METHODS Seven centers recruited pediatric patients (8–18 years of age) with heart disease (HD) and their parents to complete the PCQLI and generic health-related quality of life (Pediatric Quality of Life Inventory [PedsQL]) and non–quality of life (Self-Perception Profile for Children [SPPC]/Self-Perception Profile for Adolescents [SPPA] and Youth Self-Report [YSR]/Child Behavior Checklist [CBCL]) tools. PCQLI construct validity was assessed through correlations of PCQLI scores between patients and parents and with severity of congenital HD, medical care utilization, and PedsQL, SPPC/SPPA, and YSR/CBCL scores. PCQLI test-retest reliability was evaluated. RESULTS The study enrolled 1605 patient-parent pairs. Construct validity was substantiated by the association of lower PCQLI scores with Fontan palliation and increased numbers of cardiac operations, hospital admissions, and physician visits (P < .001); moderate to good correlations between patient and parent PCQLI scores (r = 0.41–0.61; P <.001); and fair to good correlations between PCQLI total scores and PedsQL total (r = 0.70–0.76), SPPC/SPPA global self-worth (r = 0.43–0.46), YSR/CBCL total competency (r = 0.28–0.37), and syndrome and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-oriented scale (r = −0.58 to −0.30; P < .001) scores. Test-retest reliability correlations were excellent (r = 0.78–0.90; P < .001). CONCLUSIONS PCQLI scores are valid and reliable for children and adolescents with congenital and acquired HD and may be useful for future research and clinical management.

Muscle-specific creatine kinase is thought to play an integral role in maintaining energy homeostasis by providing a supply of creatine phosphate. The genetic variant, rs8111989, contributes to individual differences in physical performance, and thus the purpose of this study was to determine if rs8111989 variant is predictive of Physical Fitness Test (PFT) scores in male, military infantry recruits. DNA was extracted from whole blood, and genotyping was performed in 176 Marines. Relationships between PFT measures (run, sit-ups, and pull-ups) and genotype were determined. Participants with 2 copies of the T allele for rs8111989 variant had higher PFT scores for run time, pull-ups, and total PFT score. Specifically, participants with 2 copies of the TT allele (variant) (n = 97) demonstrated an overall higher total PFT score as compared with those with one copy of the C allele (n = 79) (TT: 250 ± 31 vs. 238 ± 31; p = 0.02), run score (TT: 82 ± 10 vs. 78 ± 11; p = 0.04) and pull-up score (TT: 78 ± 11 vs. 65 ± 21; p = 0.04) or those with the CC/CT genotype. These results demonstrate an association between physical performance measures and genetic variation in the muscle-specific creatine kinase gene (rs8111989).

The purpose of this study was to assess whether a computerized battery of neuropsychological tests could produce similar results as the conventional forms. Comparisons on 77 volunteer undergraduates were carried out with two neuropsychological tests: Line Orientation Test and Enhanced Cued Recall Test. Firstly, students were assigned randomly across the test medium (paper-and-pencil versus computerized). Secondly, the groups were given the same test in the other medium after a 30-day interval between tests. Results showed that the Enhanced Cued Recall Test-Computer-based did not correlate with the Enhanced Cued Recall Test-Paper-and-pencil results. Line Orientation Test-Computer-based scores, on the other hand, did correlate significantly with the Line Orientation Test-Paper-and-pencil version. In both tests, scores were higher on paper-and-pencil tests compared to computer-based tests. Total score difference between modalities was statistically significant for both Enhanced Cued Recall Tests and for the Line Orientation Test. In both computer-based tests, it took less time for participants to complete the tests.

Preformulation considerations for controlled release dosage forms. Part III. Candidate form selection using numerical weighting and scoring.

Two numerical methods, Decision Analysis (DA) and Potential Problem Analysis (PPA) are presented as alternative selection methods to the logical method presented in Part I. In DA properties are weighted and outcomes are scored. The weighted scores for each candidate are totaled and final selection is based on the totals. Higher scores indicate better candidates. In PPA potential problems are assigned a seriousness factor and test outcomes are used to define the probability of occurrence. The seriousness-probability products are totaled and forms with minimal scores are preferred. DA and PPA have never been compared to the logical-elimination method. Additional data were available for two forms of McN-5707 to provide complete preformulation data for five candidate forms. Weight and seriousness factors (independent variables) were obtained from a survey of experienced formulators. Scores and probabilities (dependent variables) were provided independently by Preformulation. The rankings of the five candidate forms, best to worst, were similar for all three methods. These results validate the applicability of DA and PPA for candidate form selection. DA and PPA are particularly applicable in cases where there are many candidate forms and where each form has some degree of unfavorable properties.

While total knee arthroplasty (TKA) has been shown to have excellent outcomes, a significant proportion of patients experience relatively poor post-operative function. In this study, we test the hypothesis that the level of osteoarthritic symptoms in the contralateral knee at the time of TKA is associated with poorer post-operative outcomes in the operated knee. Using longitudinal cohort data from the Osteoarthritis Initiative (OAI), we included 171 patients who received a unilateral TKA. We compared pre-operative Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in the contralateral knee to post-operative WOMAC scores in the index knee. Pre-operative contralateral knee WOMAC scores were associated with post-operative index knee WOMAC Total scores, indicating that the health of the pre-operative contralateral knee is a significant factor in TKA outcomes.

Miyashita, Theresa L; Diakogeorgiou, Eleni; Marrie, Kaitlyn

Investigation into the effect of cumulative subconcussive head impacts has yielded various results in the literature, with many supporting a link to neurological deficits. Little research has been conducted on men's lacrosse and associated balance deficits from head impacts. (1) Athletes will commit more errors on the postseason Balance Error Scoring System (BESS) test. (2) There will be a positive correlation to change in BESS scores and head impact exposure data. Prospective longitudinal study. Level 3. Thirty-four Division I men's lacrosse players (age, 19.59 ± 1.42 years) wore helmets instrumented with a sensor to collect head impact exposure data over the course of a competitive season. Players completed a BESS test at the start and end of the competitive season. The number of errors from pre- to postseason increased during the double-leg stance on foam ( P < 0.001), tandem stance on foam ( P = 0.009), total number of errors on a firm surface ( P = 0.042), and total number of errors on a foam surface ( P = 0.007). There were significant correlations only between the total errors on a foam surface and linear acceleration ( P = 0.038, r = 0.36), head injury criteria ( P = 0.024, r = 0.39), and Gadd Severity Index scores ( P = 0.031, r = 0.37). Changes in the total number of errors on a foam surface may be considered a sensitive measure to detect balance deficits associated with cumulative subconcussive head impacts sustained over the course of 1 lacrosse season, as measured by average linear acceleration, head injury criteria, and Gadd Severity Index scores. If there is microtrauma to the vestibular system due to repetitive subconcussive impacts, only an assessment that highly stresses the vestibular system may be able to detect these changes. Cumulative subconcussive impacts may result in neurocognitive dysfunction, including balance deficits, which are associated with an increased risk for injury. The development of a strategy to reduce total number of head impacts may curb the associated sequelae. Incorporation of a modified BESS test, firm surface only, may not be recommended as it may not detect changes due to repetitive impacts over the course of a competitive season.

The aim of the study was to determine the prevalence of orthorexia nervosa among the performance artists in the State Opera and Ballet and in the Bilkent University Symphony Orchestra. The study population consisted of 39 men and 55 women for a total of 94 artists with mean age of 33 years. The ORTO-15 test was used to determine the prevalence of orthorexia nervosa. Those subjects who scored below 40 in the ORTO-15 test were classified as having orthorexia nervosa. Mean score of the participants in the ORTO-15 test was 37.9+/-4.46. A total of 56.4% of the artists involved in the research scored below 40 in the ORTO-15 test. While the highest prevalence of orthorexia nervosa was recorded among opera singers (81.8%), it was 32.1% among ballet dancers and 36.4% among symphony orchestra musicians. The differences between the three groups were statistically significant. No difference was noted between mean ORTO-15 score by baseline characteristics as gender, age, educational level, work experience, body mass index, smoking and alcohol consumption. The research group have a higher socio-economic and education level than the majority of the general public in Turkey. Additionally, being an artist in Turkey means being a role model for the general public both in terms one's physical appearance and lifestyle. These may be the reason why artists are more sensitive to this issue.

The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security) and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

To estimate the attitudes of hospital nurses towards computers and the influence of gender, age, education, and computer usage on these attitudes. The study was conducted in two Croatian hospitals where integrated hospital information system is being implemented. There were 1,081 nurses surveyed by an anonymous questionnaire consisting of 8 questions about demographic data, education, and computer usage, and 30 statements on attitudes towards computers. The statements were adapted to a Likert type scale. Differences in attitudes towards computers were compared using one-way ANOVA and Tukey-b post-hoc test. The total score was 120+/-15 (mean+/-standard deviation) out of maximal 150. Nurses younger than 30 years had a higher total score than those older than 30 years (124+/-13 vs 119+/-16 for 30-39 age groups and 117+/-15 for>39 age groups, P<0.001). Nurses with a bachelor's degree (119+/-16 vs 122+/-14, P=0.002) and nurses who had attended computer science courses had a higher total score compared to the others (124+/-13 vs 118+/-16, P<0.001). Nurses using computers more than 5 hours per week had higher total score than those who used computers less than 5 hours (127+/-13 vs 124+/-12 for 1-5 h and and 119+/-14 for <1 hour per day, P<0.001, post-hoc test). Nurses in general have positive attitudes towards computers. These results are important for the planning and implementing an integrated hospital information system.

The Mini-Mental State Exam (MMSE) is a clinically ubiquitous yet incompletely standardized instrument. Though the test offers considerable examiner leeway, little data exist on the normative consequences of common administration variations. We sought to: (a) determine the effects of education, age, gender, health status, and a common administration variation (serial 7s subtraction vs. "world" spelled backward) on MMSE score within a minority sample, (b) provide normative data stratified on the most empirically relevant bases, and (c) briefly address item failure rates. African American citizens (N = 298) aged 55-87 living independently in the community were recruited by advertisement, community recruitment, and word of mouth. Total score with "world" spelled backward exceeded total score with serial 7s subtraction across all levels of education, replicating findings in Caucasian samples. Education is the primary source of variance on MMSE score, followed by age. In this cohort, women out-performed men when "world" spelled backward was included, but there was no gender effect when serial 7s subtraction was included in MMSE total score. To ensure an appropriate interpretation of MMSE scores, reports, whether clinical or in publications of research findings, should be explicit regarding the administration method. Stratified normative data are provided.

Purpose: To create and validate scoring systems for intracerebral control (IC) and overall survival (OS) of patients irradiated for brain metastases. Methods and Materials: In this study, 1,797 patients were randomly assigned to the test (n = 1,198) or the validation group (n = 599). Two scoring systems were developed, one for IC and another for OS. The scores included prognostic factors found significant on multivariate analyses. Age, performance status, extracerebral metastases, interval tumor diagnosis to RT, and number of brain metastases were associated with OS. Tumor type, performance status, interval, and number of brain metastases were associated with IC.more » The score for each factor was determined by dividing the 6-month IC or OS rate (given in percent) by 10. The total score represented the sum of the scores for each factor. The score groups of the test group were compared with the corresponding score groups of the validation group. Results: In the test group, 6-month IC rates were 17% for 14-18 points, 49% for 19-23 points, and 77% for 24-27 points (p < 0.0001). IC rates in the validation group were 19%, 52%, and 77%, respectively (p < 0.0001). In the test group, 6-month OS rates were 9% for 15-19 points, 41% for 20-25 points, and 78% for 26-30 points (p < 0.0001). OS rates in the validation group were 7%, 39%, and 79%, respectively (p < 0.0001). Conclusions: Patients irradiated for brain metastases can be given scores to estimate OS and IC. IC and OS rates of the validation group were similar to the test group demonstrating the validity and reproducibility of both scores.« less

Background Few quality of life (QOL) assessment tools are available for children with specific chronic conditions, and none have been designed specifically for children with hearing loss (HL). A validated hearing-related QOL questionnaire could help clinicians determine whether an intervention is beneficial and whether one intervention is better than another. Purpose To examine QOL in children with HL and assess the validity, reliability, and factor structure of a new measure, the Hearing Environments and Reflection on Quality of Life (HEAR-QL) questionnaire. Research Design A descriptive and correlational study of a convenience sample of children. Study Sample Participants included 35 children with unilateral HL, 45 with bilateral HL, and 35 siblings with normal hearing. Data Collection and Analysis Children 7-12 years old were recruited by mail from a tertiary-care pediatric otolaryngology practice and the local county's Special School District. With parent consent, children completed the validated Pediatric Quality of Life Inventory™ (PedsQL™) 4.0 and a 35-item HEAR-QL questionnaire. The factor structure of the HEAR-QL was determined through principal components analysis (PCA), and mean scores were computed for each subscale and the total HEAR-QL. Three weeks following return of the initial questionnaires, a second HEAR-QL questionnaire was sent to participants to assess test-retest reliability. Both PedsQL and HEAR-QL scores were compared between children with and without HL, between children with unilateral and bilateral HL, and between children who used and did not use a hearing device using analysis of variance. Sensitivity and specificity were calculated for both the HEAR-QL and PedsQL. A multivariable, hierarchical linear regression analysis was conducted with independent variables associated with HEAR-QL in unadjusted tests. Results Using exploratory PCA, the 35-item HEAR-QL was reduced to 26 items (Cronbach's α=0.97; sensitivity 91% and specificity 92% at cut-off score of 93.5) loading on 3 factors: difficulty hearing in certain environments/situations (Environments α=0.97), impact of HL on social/sports activities (Activities α=0.92), and impact of HL on child's feelings (Feelings α=0.88). Sensitivity 78.8% and specificity 30.9% at a cut-off score of 69.6 on the PedsQL ((at-risk for impaired QOL) were lower than for the HEAR-QL. Participants with HL reported significantly lower mean total HEAR-QL scores (71 [SD 18] versus 98 [SD 5]; p < 0.001), but not mean total PedsQL scores (77 [SD 14] versus 83 [SD 15]; p = 0.47), than participants with normal hearing. Among children with bilateral HL, children who used a hearing device reported lower mean total HEAR-QL scores (p = 0.01), but not mean total PedsQL scores (p = 0.55), than children who did not use a hearing device. The intraclass correlation (ICC) for test-retest reliability for the 26-item HEAR-QL total score was .83. Hearing status and use of a device were independently associated with the HEAR-QL, and the variables in the model accounted for 46% of the HEAR-QL total score variance. Conclusion The HEAR-QL appears to be a valid, reliable, and sensitive questionnaire for children with HL. The HEAR-QL was better able than the PedsQL to distinguish between children with and without HL and can help evaluate interventions for children with HL. PMID:22212764

The Korean Version of the Sniffin' stick (KVSS) is the first olfactory test for Koreans. Although we adopted the Sniffin' Stick, we modified it to make it more suitable for Koreans. KVSS I is a screening test, and KVSS II a more comprehensive test. The aims of this study were to apply the KVSS test and assess its clinical validity and reliability in comparison to CC-SIT. One hundred and seventy-four healthy volunteers and 206 patients with subjective decreased olfaction participated. Each participant was tested with both the CC-SIT and KVSS tests and then the correlation between these two tests was analyzed. The correlation between CC-SIT and KVSS I was 0.720 (p<0.01) and 0.714 between the CC-SIT and KVSS II total scores (p<0.01). When the degree of olfaction based on the KVSS I was used, the mean CC-SIT score was 8.6+/-1.8 for normosmia, 7.3+/-2.2 for hyposmia, and 4.2+/-2.3 for anosmia. When the KVSS II total was applied, the mean CC-SIT score was 8.4+/-1.8 for normosmia, 7.3+/-2.0 for hyposmia, and 3.7+/-2.0 for anosmia. The means of the three group differed significantly in both cases (p<0.01). Thus, the KVSS test demonstrates validity and reliability for Korean in comparison with CC-SIT.

It has been hypothesized that glutamatergic transmission may be altered in Tourette syndrome. In this study, we explored the efficacy of a glutamate agonist (D-serine) and antagonist (riluzole) as tic-suppressing agents in children with Tourette syndrome. We performed a parallel three-arm, 8-week, double-blind, randomized placebo-controlled treatment study in children with Tourette syndrome. Each child received 6 weeks of treatment with D-serine (maximum dose 30 mg/kg/day), riluzole (maximum dose 200 mg/day), or placebo, followed by a 2-week taper. The primary outcome measure was effective tic suppression as determined by the differences in the Yale Global Tic Severity Scale score; specifically, the total tic score and the combined score (total tic score + global impairment) between treatment arms after 6 weeks of treatment. Mann-Whitney U tests were performed to analyze differences between each group and the placebo group. Twenty-four patients (males = 21, ages 9-18) enrolled in the study; one patient dropped out before completion. Combined Yale Global Tic Severity Scale score and total tic scores improved in all groups. The 6-week mean percent improvement of the riluzole (n = 10), D-serine (n = 9), and placebo (n = 5) groups in the combined Yale Global Tic Severity Scale score were 43.7, 39.5, and 30.2 and for total tic scores were 38.0, 25.0, and 34.0, respectively. There were no significant differences in Yale Global Tic Severity Scale score or total tic score, respectively, between the riluzole and placebo (P = 0.35, 0.85) or D-serine and placebo (P = 0.50, 0.69) groups. Tics diminished by comparable percentages in the riluzole, D-serine, and placebo groups. These preliminary data suggest that D-serine and riluzole are not effective in tic suppression.

Chronic kidney-disease screening service quality: questionnaire survey research evidence from Taichung city

PubMed Central

2009-01-01

Background Chronic kidney disease (CKD) is a serious public health problem in Taiwan and the world. The most effective, affordable treatments involve early prevention/detection/intervention, requiring screening. Successfully implementing CKD programs requires good patient participation, affected by patient perceptions of screening service quality. Service quality improvements can help make such programs more successful. Thus, good tools for assessing service quality perceptions are important. Aim: to investigate using a modified SERVQUAL questionnaire in assessing patient expectations, perceptions, and loyalty towards kidney disease screening service quality. Method 1595 kidney disease screening program patients in Taichung City were requested to complete and return a modified kidney disease screening SERVQUAL questionnaire. 1187 returned them. Incomplete ones (102) were culled and 1085 were chosen as effective for use. Paired t-tests, correlation tests, ANOVA, LSD test, and factor analysis identified the characteristics and factors of service quality. The paired t-test tested expectation score and perception score gaps. A structural equation modeling system examined satisfaction-based components' relationships. Results The effective response rate was 91.4%. Several methods verified validity. Cronbach's alpha on internal reliability was above 0.902. On patient satisfaction, expectation scores are high: 6.50 (0.82), but perception scores are significantly lower 6.14 (1.02). Older patients' perception scores are lower than younger patients'. Expectation and perception scores for patients with different types of jobs are significantly different. Patients higher on education have lower scores for expectation (r = -0.09) and perception (r = -0.26). Factor analysis identified three factors in the 22 item SERVQUAL form, which account for 80.8% of the total variance for the expectation scores and 86.9% of the total variance for the satisfaction scores. Expectation and perception score gaps in all 22 items are significant. The goodness-of-fit summary of the SEM results indicates that expectations and perceptions are positively correlated, perceptions and loyalty are positively correlated, but expectations and loyalty are not positively correlated. Conclusions The results of this research suggest that the SERVQUAL instrument is a useful measurement tool in assessing and monitoring service quality in kidney disease screening services, enabling the staff to identify where service improvements are needed from the patients' perspectives.

Early-life stress (ELS) may mediate adjustment problems while resilience may protect individuals against adjustment problems during military service. We investigated the relationship of ELS and resilience with adjustment problem factor scores in the Korea Military Personality Test (KMPT) in candidates for the military service. Four hundred and sixty-one candidates participated in this study. Vulnerability traits for military adjustment, ELS, and resilience were assessed using the KMPT, the Korean Early-Life Abuse Experience Questionnaire, and the Resilience Quotient Test, respectively. Data were analyzed using multiple linear regression analyses. The final model of the multiple linear regression analyses explained 30.2 % of the total variances of the sum of the adjustment problem factor scores of the KMPT. Neglect and exposure to domestic violence had a positive association with the total adjustment problem factor scores of the KMPT, but emotion control, impulse control, and optimism factor scores as well as education and occupational status were inversely associated with the total military adjustment problem score. ELS and resilience are important modulating factors in adjusting to military service. We suggest that neglect and exposure to domestic violence during early life may increase problem with adjustment, but capacity to control emotion and impulse as well as optimistic attitude may play protective roles in adjustment to military life. The screening procedures for ELS and the development of psychological interventions may be helpful for young adults to adjust to military service.

The purpose of the study was to use the cumulative summation (CUSUM) test to assess the learning curve during the introduction of a new surgical technique (patient-specific instrumentation) in total knee arthroplasty (TKA) in an academic department. The first 50TKAs operated on at an academic department using patient-specific templates (PSTs) were scheduled to enter the study. All patients had a preoperative computed tomography scan evaluation to plan bone resections. The PSTs were positioned intraoperatively according to the best-fit technique and their three-dimensional orientation was recorded by a navigation system. The position of the femur and tibia PST was compared to the planned position for four items for each component: coronal and sagittal orientation, medial and lateral height of resection. Items were summarized to obtain knee, femur and tibia PST scores, respectively. These scores were plotted according to chronological order and included in a CUSUM analysis. The tested hypothesis was that the PST process for TKA was immediately under control after its introduction. CUSUM test showed that positioning of the PST significantly differed from the target throughout the study. There was a significant difference between all scores and the maximal score. No case obtained the maximal score of eight points. The study was interrupted after 20 cases because of this negative evaluation. The CUSUM test is effective in monitoring the learning curve when introducing a new surgical procedure. Introducing PST for TKA in an academic department may be associated with a long-lasting learning curve. The study was registered on the clinical.gov website (Identifier NCT02429245).

Purpose This study examined the reliability and validity of the Test of Infant Motor Performance Screening Items (TIMPSI) in infants with type I spinal muscular atrophy (SMA). Methods After training, 12 evaluators scored 4 videos of infants with type I SMA to assess interrater reliability. Intrarater and test-retest reliability was further assessed for 9 evaluators during a SMA type I clinical trial, with 9 evaluators testing a total of 38 infants twice. Relatedness of the TIMPSI score to ability to reach and ventilatory support was also examined. Results Excellent interrater video score reliability was noted (intraclass correlation coefficient, 0.97–0.98). Intrarater reliability was excellent (intraclass correlation coefficient, 0.91–0.98) and test-retest reliability ranged from r = 0.82 to r = 0.95. The TIMPSI score was related to the ability to reach (P ≤ .05). Conclusion The TIMPSI can reliably be used to assess motor function in infants with type I SMA. In addition, the TIMPSI scores are related to the ability to reach, an important functional skill in children with type I SMA. PMID:23542189

The aim of this study was to compare the Persian version of the wechsler intelligence scale for children - fourth edition (WISC-IV) and cognitive assessment system (CAS) tests, to determine the correlation between their scales and to evaluate the probable concurrent validity of these tests in patients with learning disorders. One-hundered-sixty-two children with learning disorder who were presented at Atieh Comprehensive Psychiatry Center were selected in a consecutive non-randomized order. All of the patients were assessed based on WISC-IV and CAS scores questionnaires. Pearson correlation coefficient was used to analyze the correlation between the data and to assess the concurrent validity of the two tests. Linear regression was used for statistical modeling. The type one error was considered 5% in maximum. There was a strong correlation between total score of WISC-IV test and total score of CAS test in the patients (r=0.75, P<0.001). The correlations among the other scales were mostly high and all of them were statistically significant (P<0.001). A linear regression model was obtained (α = 0.51, β = 0.81 and P<0.001). There is an acceptable correlation between the WISC-IV scales and CAS test in children with learning disorders. A concurrent validity is established between the two tests and their scales.

The changing hormonal milieu during the menopausal transition may contribute to the development of memory disorders. We aimed to assess the association of sex hormones with memory function in a sample of Greek middle-aged women. This pilot study included 44 women with subjective memory complaints. Memory performance was evaluated using the Hopkins Verbal Learning Test (HVLT), the Brief Visuospatial Memory test (BVMT), and the verbal digits backwards test (VSPAN), to assess verbal, visuospatial, and working memory performance, respectively. Menopausal symptoms were assessed using the Green Climacteric Scale. VSPAN backwards scores were positively associated with log-transformed free androgen index (logFAI), in models adjusted for age, education, log-transformed free estrogen index (logFEI), hypertension, and the intensity of menopausal symptoms. BVMT total scores were predicted by logFAI (b-coefficient = 0.424, p value = 0.002), education, and combined climacteric symptomatology, in a model adjusted for age, logFEI, and hypertension. Women with circulating estradiol above the median value of 10 pg/mL had better total HTLV total scores compared to women with estradiol values below the median (HTLV total scores, estradiol ≤ 10 pg/mL vs. > 10 pg/mL: 24.2 ± 3.6 vs. 30.0 ± 7.9, p value = 0.007 unadjusted). This association was affected by education and remained independent of menopausal symptoms and testosterone levels, education, and hypertension (model R 2 = 22.3%; b-coefficient = 0.318, p value = 0.024). Endogenous total estradiol is associated with verbal episodic memory, while logFAI is associated with working memory performance and visuospatial episodic memory in this sample of postmenopausal women. These associations were not influenced by age, education, or menopausal symptoms. Larger studies are necessary to evaluate the significance of our findings.

To examine among alcohol-dependent out-patient clients the concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) total score and 'zones' suggested by the World Health Organization for defining levels of severity of alcohol use problems. Participants were classified into AUDIT zones (AUDIT total score = 8-15, 16-19, 20-40) and compared on measures of demographics, treatment goals, alcohol consumption, alcohol-related consequences, severity of dependence, physiological dependence, tolerance, withdrawal and biomarkers of alcohol use. Eleven out-patient academic clinical research centers across the United States. Participants Alcohol dependent individuals (n = 1335) entering out-patient treatment in the Combined Pharmacotherapies and Behavioral Interventions (COMBINE) study. The AUDIT was administered as part of an initial screening. Baseline measures used for concurrent validation included the Structured Clinical Interview for Diagnostic and Statistical Manual, 4th edition (DSM-IV) Disorders, the Alcohol Dependence Scale, the Drinker Inventory of Consequences, the Obsessive-Compulsive Drinking Scale, the University of Rhode Island Change Assessment, the Thoughts about Abstinence Scale, the Form-90, %carbohydrate-deficient transferrin and gamma-glutamyl transferase. Findings Indicators of severity of dependence and alcohol-related problems increased linearly with total score and differed significantly across AUDIT zones. The highest zone, with scores of 20 and above, was markedly different with respect to severity from the other two zones and members of this group endorsed an abstinence goal more strongly. The AUDIT total score is a brief measure that appears to provide an index of severity of dependence in a sample of alcohol-dependent individuals seeking out-patient treatment, extending its potential utility beyond its more traditional role as a screening instrument in general populations.

Objective The aim of the present study was to translate and cross-culturally adapt the Functional Status Score for the intensive care unit (FSS-ICU) into Brazilian Portuguese. Methods This study consisted of the following steps: translation (performed by two independent translators), synthesis of the initial translation, back-translation (by two independent translators who were unaware of the original FSS-ICU), and testing to evaluate the target audience's understanding. An Expert Committee supervised all steps and was responsible for the modifications made throughout the process and the final translated version. Results The testing phase included two experienced physiotherapists who assessed a total of 30 critical care patients (mean FSS-ICU score = 25 ± 6). As the physiotherapists did not report any uncertainties or problems with interpretation affecting their performance, no additional adjustments were made to the Brazilian Portuguese version after the testing phase. Good interobserver reliability between the two assessors was obtained for each of the 5 FSS-ICU tasks and for the total FSS-ICU score (intraclass correlation coefficients ranged from 0.88 to 0.91). Conclusion The adapted version of the FSS-ICU in Brazilian Portuguese was easy to understand and apply in an intensive care unit environment. PMID:28444070

This study investigated convergent and discriminant validity between two motor competence assessment instruments in 2485 Flemish children: the Bruininks-Oseretsky Test of Motor Proficiency 2 Short Form (BOT-2 Short Form) and the KörperKoördinationsTest für Kinder (KTK). A Pearson correlation assessed the relationship between BOT-2 Short Form total, gross and fine motor composite scores and KTK Motor Quotient in three age cohorts (6-7, 8-9, 10-11 years). Crosstabs were used to measure agreement in classification in children scoring below percentile 5 and 15 and above percentile 85 and 95. Moderately strong positive (r=0.44-0.64) associations between BOT-2 total and gross motor composite scores and KTK Motor Quotient and weak positive correlations between BOT-2 Short Form fine motor composite and KTK Motor Quotient scores (r=0.25-0.37) were found. Levels of agreement were fair to moderate. Therefore, some proof of convergent and discriminant validity between BOT-2 Short Form and KTK was established in this study, underlining the notion that the evaluation of motor competence should not be based upon a single assessment instrument.

To investigate the added value of myocardial perfusion scintigraphy imaging (MPI) in consecutive patients with suspected coronary artery disease (CAD) and a recent, normal exercise electrocardiography (ECG). This study was a retrospective analysis of consecutive patients referred for MPI during a 2-year period from 2006-2007 at one clinic. All eligible patients were suspected of suffering from CAD, and had performed a satisfactory bicycle exercise test (i.e., peak heart rate > 85% of the expected, age-predicted maximum) within 6 mo of referral, their exercise ECG was had no signs of ischemia, there was no exercise-limiting angina, and no cardiac events occurred between the exercise test and referral. The patients subsequently underwent a standard 2-d, stress-rest exercise MPI. Ischemia was defined based on visual scoring supported by quantitative segmental analysis (i.e., sum of stress score > 3). The results of cardiac catheterization were analyzed, and clinical follow up was performed by review of electronic medical files. A total of 56 patients fulfilled the eligibility criteria. Most patients had a low or intermediate ATPIII pre-test risk of CAD (6 patients had a high pre-test risk). The referral exercise test showed a mean Duke score of 5 (range: 2 to 11), which translated to a low post-exercise risk in 66% and intermediate risk in 34%. A total of seven patients were reported with ischemia by MPI. Three of these patients had high ATPIII pre-test risk scores. Six of these seven patients underwent cardiac catheterization, which showed significant stenosis in one patient with a high pre-test risk of CAD, and indeterminate lesions in three patients (two of whom had high pre-test risk scores). With MPI as a gate keeper for catheterization, no significant, epicardial stenosis was observed in any of the 50 patients (0%, 95% confidence interval 0.0 to 7.1) with low to intermediate pre-test risk of CAD and a negative exercise test. No cardiac events occurred in any patients within a median follow up period of > 1200 d. The added diagnostic value of MPI in patients with low or intermediate risk of CAD and a recent, normal exercise test is marginal.

Planning or something else? Examining neuropsychological predictors of Zoo Map performance.

Oosterman, Joukje M; Wijers, Marijn; Kessels, Roy P C

2013-01-01

The Zoo Map Test of the Behavioral Assessment of the Dysexecutive Syndrome battery is often applied to measure planning ability as part of executive function. Successful performance on this test is, however, dependent on various cognitive functions, and deficient Zoo Map performance does therefore not necessarily imply selectively disrupted planning abilities. To address this important issue, we examined whether planning is still the most important predictor of Zoo Map performance in a heterogeneous sample of neurologic and psychiatric outpatients (N = 71). In addition to the Zoo Map Test, the patients completed other neuropsychological tests of planning, inhibition, processing speed, and episodic memory. Planning was the strongest predictor of the total raw score and inappropriate places visited, and no additional contribution of other cognitive scores was found. One exception to this was the total time, which was associated with processing speed. Overall, our findings indicate that the Zoo Map Test is a valid indicator of planning ability in a heterogeneous patient sample.

To test if the Finnish Defence Forces Basic Intellectual Ability Test scores at 20.1 years predicted risk of organic dementia or Alzheimer disease (AD). Dementia was defined as inpatient or outpatient diagnosis of organic dementia or AD risk derived from Hospital Discharge or Causes of Death Registers in 2,785 men from the Helsinki Birth Cohort Study, divided based on age at first diagnosis into early onset (<65 years) or late onset (≥65 years). The Finnish Defence Forces Basic Intellectual Ability Test comprises verbal, arithmetic, and visuospatial subtests and a total score (scores transformed into a mean of 100 and SD of 15). We used Cox proportional hazard models and adjusted for age at testing, childhood socioeconomic status, mother's age at delivery, parity, participant's birthweight, education, and stroke or coronary heart disease diagnosis. Lower cognitive ability total and verbal ability (hazard ratio [HR] per 1 SD disadvantage >1.69, 95% confidence interval [CI] 1.01-2.63) scores predicted higher early-onset any dementia risk across the statistical models; arithmetic and visuospatial ability scores were similarly associated with early-onset any dementia risk, but these associations weakened after covariate adjustments (HR per 1 SD disadvantage >1.57, 95% CI 0.96-2.57). All associations were rendered nonsignificant when we adjusted for participant's education. Cognitive ability did not predict late-onset dementia risk. These findings reinforce previous suggestions that lower cognitive ability in early life is a risk factor for early-onset dementia. © 2018 American Academy of Neurology.

To conduct a meta-analysis of clinical trials that examined the effect of music-supported therapy on stroke-induced motor dysfunction, comprehensive literature searches of PubMed, Embase and the Cochrane Library from their inception to April 2016 were performed. A total of 10 studies (13 analyses, 358 subjects) were included; all had acceptable quality according to PEDro scale score. The baseline differences between the two groups were confirmed to be comparable. Compared with the control group, the standardized mean difference of 9-Hole Peg Test was 0.28 (−0.01, 0.57), 0.64 (0.31, 0.97) in Box and Block Test, 0.47 (0.08, 0.87) in Arm Paresis Score and 0.35 (−0.04, 0.75) in Action Research Arm Test for upper-limb motor function, 0.11 (−0.24, 0.46) in Berg Balance Scale score, 0.09 (−0.36, 0.54) in Fugl-Meyer Assessment score, 0.30 (−0.15, 0.74) in Wolf Motor Function Test, 0.30 (−0.15, 0.74) in Wolf Motor Function time, 0.65 (0.14, 1.16) in Stride length and 0.62 (0.01, 1.24) in Gait Velocity for total motor function, and 1.75 (0.94, 2.56) in Frontal Assessment Battery score for executive function. There was evidence of a positive effect of music-supported therapy, supporting its use for the treatment of stroke-induced motor dysfunction. This study was registered at PRESPERO (CRD42016037106).

Micronutrient deficiencies and suboptimal energy intake are widespread in rural Kenya, with detrimental effects on child growth and development. Sporadic school feeding programmes rarely include animal source foods (ASF). In the present study, a cluster-randomised feeding trial was undertaken to determine the impact of snacks containing ASF on district-wide, end-term standardised school test scores and nutrient intake. A total of twelve primary schools were randomly assigned to one of three isoenergetic feeding groups (a local plant-based stew (githeri) with meat, githeri plus whole milk or githeri with added oil) or a control group receiving no intervention feeding. After the initial term that served as baseline, children were fed at school for five consecutive terms over two school years from 1999 to 2001. Longitudinal analysis was used controlling for average energy intake, school attendance, and baseline socio-economic status, age, sex and maternal literacy. Children in the Meat group showed significantly greater improvements in test scores than those in all the other groups, and the Milk group showed significantly greater improvements in test scores than the Plain Githeri (githeri+oil) and Control groups. Compared with the Control group, the Meat group showed significant improvements in test scores in Arithmetic, English, Kiembu, Kiswahili and Geography. The Milk group showed significant improvements compared with the Control group in test scores in English, Kiswahili, Geography and Science. Folate, Fe, available Fe, energy per body weight, vitamin B₁₂, Zn and riboflavin intake were significant contributors to the change in test scores. The greater improvements in test scores of children receiving ASF indicate improved academic performance, which can result in greater academic achievement.

The determination of aminopyrine breath test on entry into the study was recently shown to improve the accuracy of prediction of death based on the Child-Pugh classification, but the possible usefulness of serial determinations of both parameters has not been assessed. In the present study, we aimed at evaluating whether serial determinations of aminopyrine breath test and Child-Pugh score improve prognostic accuracy in patients with cirrhosis, compared with determinations obtained only on admission. In 74 patients with liver cirrhosis aminopyrine breath test and Child-Pugh score were obtained upon entry into the study. Patients were followed with sequential aminopyrine breath tests and assessments of the Child-Pugh score every 4-6 months. A total number of 232 determinations were obtained. During follow-up 45 patients died, on average after 12 months of follow-up. Child-Pugh score improved in the beginning of follow-up, and then remained fairly constant; aminopyrine breath test showed no improvement in the beginning of follow-up, but rather a slowly progressive decline. In patients who died, both the Child-Pugh score and the metabolism of aminopyrine were significantly more impaired in the last year preceding death (p < 0.05). Applying Cox's regression model with time-dependent covariates, Child-Pugh score and aminopyrine breath test were independent significant predictors of survival. The model with time-dependent covariates explained the observed survival much better than the model with time-fixed covariates (chi-sq. explained by regression = 31.45 vs 11.97; d.f. = 2; p = 0.0000001 vs 0.003). These data suggest that serial determinations of Child-Pugh score and aminopyrine breath test can be used to efficiently update prognosis of cirrhosis.

The psychological construct of 'therapeutic alliance' can be used to better understand the effectiveness of consultations, particularly goal setting for weight management. We analysed audio-recorded health coaching sessions during a weight loss trial to explore relationships between therapeutic alliance and various contextual factors. Audio recordings of 50 health coaching sessions were analysed. After assessing fidelity to the protocol, therapeutic alliance was measured using an adapted Working Alliance Inventory Observer-rated Short Version (WAI-O-S), and examined by (i) identifying relationships between contextual factors and WAI-O-S scores (Spearman's coefficients); (ii) testing the impact of preparatory exercises and body mass index on WAI-O-S scores (one-way analysis of variance and least-squared differences tests) and (iii) comparing differences in WAI-O-S scores based on relationship status, gender and follow-up session completion (independent samples t-tests). Fidelity was high (mean 88%). WAI-O-S total scores ranged from 55 to 70 (out of 84). Session duration was significantly correlated with WAI-O-S component of 'Bond' (r = 0.42, P = 0.002). Those who completed preparatory exercises had significantly higher total WAI-O-S scores, 'Goal' and 'Task' scores. Participants who completed the follow-up session scored significantly higher for 'Goal' compared to no follow-up. Spending more time in a session appears related to increased bonding, a key component of therapeutic alliance. Preparatory work may help build therapeutic alliance and agreement on goals appears to influence follow-up completion. These exploratory findings provide directions for research addressing the professional relationship in dietetic consultations for weight loss. © 2018 Dietitians Association of Australia.

The aim was to evaluate the relationship between orofacial function, dentofacial morphology, and bite force in young subjects. Three hundred and sixteen subjects were divided according to dentition stage (early, intermediate, and late mixed and permanent dentition). Orofacial function was screened using the Nordic Orofacial Test-Screening (NOT-S). Orthodontic treatment need, bite force, lateral and frontal craniofacial dimensions and presence of sleep bruxism were also assessed. The results were submitted to descriptive statistics, normality and correlation tests, analysis of variance, and multiple linear regression to test the relationship between NOT-S scores and the studied independent variables. The variance of NOT-S scores between groups was not significant. The evaluation of the variables that significantly contributed to NOT-S scores variation showed that age and presence of bruxism related to higher NOT-S total scores, while the increase in overbite measurement and presence of closed lip posture related to lower scores. Bite force did not show a significant relationship with scores of orofacial dysfunction. No significant correlations between craniofacial dimensions and NOT-S scores were observed. Age and sleep bruxism were related to higher NOT-S scores, while the increase in overbite measurement and closed lip posture contributed to lower scores of orofacial dysfunction. © 2013 John Wiley & Sons A/S.

The authors conducted a population-based study to attempt to estimate the effect of human immunodeficiency virus type 1 (HIV-1) seropositivity on Armed Services Vocational Aptitude Battery test scores in otherwise healthy individuals with early HIV-1 infection. The Armed Services Vocational Aptitude Battery is a 10-test written multiple aptitude battery administered to all civilian applicants for military enlistment prior to serologic screening for HIV-1 antibodies. A total of 975,489 induction testing records containing both Armed Services Vocational Aptitude Battery and HIV-1 results from October 1985 through March 1987 were examined. An analysis data set (n = 7,698) was constructed by choosing five controls for each of the 1,283 HIV-1-positive cases, matched on five-digit ZIP code, and a multiple linear regression analysis was performed to control for demographic and other factors that might influence test scores. Years of education was the strongest predictor of test scores, raising an applicant's score on a composite test nearly 0.16 standard deviation per year. The HIV-1-positive effect on the composite score was -0.09 standard deviation (99% confidence interval -0.17 to -0.02). Separate regressions on each component test within the battery showed HIV-1 effects between -0.39 and +0.06 standard deviation. The two Armed Services Vocational Aptitude Battery component tests felt a priori to be the most sensitive to HIV-1-positive status showed the least decrease with seropositivity. Much of the variability in test scores was not predicted by either HIV-1 serostatus or the demographic and other factors included in the model. There appeared to be little evidence of a strong HIV-1 effect.

Background White matter hyperintensities (WMHs) are associated with vascular cognitive impairment (VCI) but fail to correlate with neuropsychological measures. As proton MR spectroscopy (1H-MRS) can identify ischaemic tissue, we hypothesised that MRS detectable brain metabolites would be superior to WMHs in predicting performance on neuropsychological tests. Methods 60 patients with suspected VCI underwent clinical, neuropsychological, MRI and CSF studies. They were diagnosed as having subcortical ischaemic vascular disease (SIVD), multiple infarcts, mixed dementia and leukoaraiosis. We measured brain metabolites in a white matter region above the lateral ventricles with 1H-MRS and WMH volume in this region and throughout the brain. Results We found a significant correlation between both total creatine (Cr) and N-acetylaspartyl compounds (NAA) and standardised neuropsychological test scores. Cr levels in white matter correlated significantly with executive function (p=0.001), attention (p=0.03) and overall T score (p=0.007). When lesion volume was added as a covariate, NAA also showed a significant correlation with executive function (p=0.003) and overall T score (p=0.015). Furthermore, while metabolite levels also correlated with total white matter lesion volume, adjusting the Cr levels for lesion volume did not diminish the strength of the association between Cr levels and neuropsychological scores. The lowest metabolite levels and neuropsychological scores were found in the SIVD group. Finally, lesion volume alone did not correlate significantly with any neuropsychological test score. Conclusion These results suggest that estimates of neurometabolite levels provide additional and useful information concerning cognitive function in VCI not obtainable by measurements of lesion load.

The Oxford Knee Score (OKS) is a valid, short, self-administered, and site- specific outcome measure specifically developed for patients with knee arthroplasty. This study aimed to cross-culturally adapt and validate the OKS to be used in Turkish-speaking patients with osteoarthritis of the knee. The OKS was translated and culturally adapted according to the guidelines in the literature. Ninety-one patients (mean age: 55.89±7.85 years) with knee osteoarthritis participated in the study. Patients completed the Turkish version of the Oxford Knee Score (OKS-TR), Short-Form 36 Health Survey (SF-36), and Western Ontario and McMaster Universities Index (WOMAC) questionnaires. Internal consistency was tested using Cronbach's α coefficient. Patients completed the OKS-TR questionnaire twice in 7 days to determine the reproducibility. Correlation between the total results of both tests was determined by Spearman's correlation coefficient and intraclass correlation coefficients (ICC). Validity was assessed by calculating Spearman's correlation coefficient between the OKS, WOMAC, and SF-36 scores. Floor and ceiling effects were analyzed. Internal consistency was high (Cronbach's α: 0.90). The reproducibility tested by 2 different methods showed no significant difference (p>0.05). The construct validity analyses showed a significant correlation between the OKS and the other scores (p<0.05). There was no floor or ceiling effect in total OKS score. The OKS-TR is a reliable and valid measure for the self-assessment of pain and function in Turkish-speaking patients with osteoarthritis of the knee.

To evaluate the theory of mind in autism spectrum disorders (ASD) and control individuals by applying the Strange Stories test that was translated and adapted to the Portuguese language. Twenty-eight children with ASD and 56 controls who were all male and aged between 6 and 12 years participated in the study. There were significant differences between the median scores of the groups for each of the 12 stories of the test and for the sum total of all the median scores. The median scores for all stories were significantly greater in the control group than those in the experimental group (children with ASD). In addition, the protocol had excellent internal consistency. The theory of mind skills assessed with the Strange Stories test indicated alterations in children with ASD compared with children in the control group.

The purpose of this archival study was to identify performance validity tests (PVTs) and standard IQ and neurocognitive test scores, which singly or in combination, differentiate credible patients of low IQ (FSIQ ≤ 75; n = 55) from non-credible patients. We compared the credible participants against a sample of 74 non-credible patients who appeared to have been attempting to feign low intelligence specifically (FSIQ ≤ 75), as well as a larger non-credible sample (n = 383) unselected for IQ. The entire non-credible group scored significantly higher than the credible participants on measures of verbal crystallized intelligence/semantic memory and manipulation of overlearned information, while the credible group performed significantly better on many processing speed and memory tests. Additionally, credible women showed faster finger-tapping speeds than non-credible women. The credible group also scored significantly higher than the non-credible subgroup with low IQ scores on measures of attention, visual perceptual/spatial tasks, processing speed, verbal learning/list learning, and visual memory, and credible women continued to outperform non-credible women on finger tapping. When cut-offs were selected to maintain approximately 90% specificity in the credible group, sensitivity rates were highest for verbal and visual memory measures (i.e., TOMM trials 1 and 2; Warrington Words correct and time; Rey Word Recognition Test total; RAVLT Effort Equation, Trial 5, total across learning trials, short delay, recognition, and RAVLT/RO discriminant function; and Digit Symbol recognition), followed by select attentional PVT scores (i.e., b Test omissions and time to recite four digits forward). When failure rates were tabulated across seven most sensitive scores, a cut-off of ≥ 2 failures was associated with 85.4% specificity and 85.7% sensitivity, while a cut-off of ≥ 3 failures resulted in 95.1% specificity and 66.0% sensitivity. Results are discussed in light of extant literature and directions for future research.

Survival scores for patients with brain metastasis exist. However, the treatment regimens used to create these scores were heterogeneous. This study aimed to develop and validate a survival score in homogeneously treated patients. Eight-hundred-and-eighty-two patients receiving 10 × 3Gy of WBRT alone were randomly assigned to a test group (N=441) or a validation group (N=441). In the multivariate analysis of the test group, age, performance status, extracranial metastasis, and systemic treatment prior to WBRT were independent predictors of survival. The score for each factor was determined by dividing the 6-month survival rate (in %) by 10. Scores were summed and total scores ranged from 6 to 19 points. Patients were divided into four prognostic groups. The 6-month survival rates were 4% for 6-9 points, 29% for 10-14 points, 62% for 15-17 points, and 93% for 17-18 points (p<0.001) in the test group. The survival rates were 3%, 28%, 54% and 96%, respectively (p<0.001) in the validation group. Since the 6-month survival rates in the validation group were very similar to the test group, this new score (WBRT-30) appears valid and reproducible. It can help making treatment choices and stratifying patients in future trials. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Moral sensitivity is a life-long cognitive ability. It is expected that nurses who work in a professional purpose at "curing human beings" should have a highly developed moral sensitivity. The general opinion is that ethics education plays a significant role in this sense to enhance the moral sensitivity in terms of nurses' professional behaviors and distinguish ethical violations. This study was conducted as intervention research for the purpose of determining the effect of the ethics training on fourth-year students of the nursing department recognizing ethical violations experienced in the hospital and developing ethical sensitivity. The study was conducted with 50 students, with 25 students each in the experiment and control groups. Students in the experiment group were provided ethics training and consultancy services. The data were collected through the data collection form, which consists of questions on the socio-demographic characteristics and ethical sensitivity of the students, Moral Sensitivity Questionnaire, and the observation form on ethical principle violations/protection in the clinic environment. The data were digitized on the computer with the SPSS for Windows 13.0 program. The data were evaluated utilizing number, percentile calculation, paired samples t-test, Wilcoxon test, and the McNemar test. The total Moral Sensitivity Questionnaire pre-test score averages of students in the experiment group were determined to be 93.88 ± 13.57, and their total post-test score averages were determined to be 89.24 ± 15.90. The total pre-test score averages of students in the control group were determined to be 91.48 ± 17.59, and their total post-test score averages were determined to be 97.72 ± 19.91. In the study, it was determined that the post-training ethical sensitivity of students in the experiment group increased; however, this was statistically not significant. Furthermore, it was determined that the number of ethical principle protection/violation observations and correct examples provided by students in the experiment group were higher than the control group and the difference was statistically significant. Written permission and ethical approval were obtained from the university where the study was conducted. Written consent was received from students accepting to participate in the study. As a result, ethics education given to students enables them to distinguish ethical violations in a hospital and make a proper observation in this issue. © The Author(s) 2014.

Use of neuropsychological tests to identify HIV-associated neurocognitive dysfunction must involve normative standards that are well-suited to the population of interest. Norms should be based on a population of HIV-uninfected individuals as closely matched to the HIV-infected group as possible, and must include examination of the potential effects of demographic factors on test performance. This is the first study to determine the normal range of scores on measures of psychomotor speed and executive function among a large group of ethnically and educationally diverse HIV-uninfected, high risk women, as well as their HIV-infected counterparts. Participants (n = 1653) were administered the Trailmaking Test Parts A and B (Trails A and Trails B), the Symbol Digit Modalities Test (SDMT), and the Wide Range Achievement Test-3 (WRAT-3). Among HIV-uninfected women, race/ethnicity accounted for almost 5% of the variance in cognitive test performance. The proportion of variance in cognitive test performance accounted for by age (13.8%), years of school (4.1%) and WRAT-3 score (11.5%) were each significant, but did not completely account for the effect of race (3%). HIV-infected women obtained lower scores than HIV-uninfected women on time to complete Trails A and B, SDMT total correct, and SDMT incidental recall score, but after adjustment for age, years of education, racial/ethnic classification, and reading level, only the difference on SDMT total correct remained significant. Results highlight the need to adjust for demographic variables when diagnosing cognitive impairment in HIV-infected women. Advantages of demographically adjusted regression equations developed using data from HIV-uninfected women are discussed. PMID:21950512

Evaluating the Impact of EBP Education: Development of a Modified Fresno Test for Acute Care Nursing.

2018-05-14

Proficiency in evidence-based practice (EBP) is essential for relevant research findings to be integrated into clinical care when congruent with patient preferences. Few valid and reliable tools are available to evaluate the effectiveness of educational programs in advancing EBP attitudes, knowledge, skills, or behaviors, and ongoing competency. The Fresno test is one objective method to evaluate EBP knowledge and skills; however, the original and modified versions were validated with family physicians, physical therapists, and speech and language therapists. To adapt the Modified Fresno-Acute Care Nursing test and develop a psychometrically sound tool for use in academic and practice settings. In Phase 1, modified Fresno (Tilson, 2010) items were adapted for acute care nursing. In Phase 2, content validity was established with an expert panel. Content validity indices (I-CVI) ranged from .75 to 1.0. Scale CVI was .95%. A cross-sectional convenience sample of acute care nurses (n = 90) in novice, master, and expert cohorts completed the Modified Fresno-Acute Care Nursing test administered electronically via SurveyMonkey. Total scores were significantly different between training levels (p < .0001). Novice nurses scored significantly lower than master or expert nurses, but differences were not found between the latter cohorts. Total score reliability was acceptable: (interrater [ICC (2, 1)]) = .88. Cronbach's alpha was 0.70. Psychometric properties of most modified items were satisfactory; however, six require further revision and testing to meet acceptable standards. The Modified Fresno-Acute Care Nursing test is a 14-item test for objectively assessing EBP knowledge and skills of acute care nurses. While preliminary psychometric properties for this new EBP knowledge measure for acute care nursing are promising, further validation of some of the items and scoring rubric is needed. © 2018 Sigma Theta Tau International.

Considerable evidence suggests that how candidates react to selection procedures can affect their test performance and their attitudes toward the hiring organization (e.g., recommending the firm to others). However, very few studies of candidate reactions have examined one of the outcomes organizations care most about: job performance. We attempt to address this gap by developing and testing a conceptual framework that delineates whether and how candidate reactions might influence job performance. We accomplish this objective using data from 4 studies (total N = 6,480), 6 selection procedures (personality tests, job knowledge tests, cognitive ability tests, work samples, situational judgment tests, and a selection inventory), 5 key candidate reactions (anxiety, motivation, belief in tests, self-efficacy, and procedural justice), 2 contexts (industry and education), 3 continents (North America, South America, and Europe), 2 study designs (predictive and concurrent), and 4 occupational areas (medical, sales, customer service, and technological). Consistent with previous research, candidate reactions were related to test scores, and test scores were related to job performance. Further, there was some evidence that reactions affected performance indirectly through their influence on test scores. Finally, in no cases did candidate reactions affect the prediction of job performance by increasing or decreasing the criterion-related validity of test scores. Implications of these findings and avenues for future research are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved

Introduction: Appropriate instructional design plays a crucial role in e-learning success, and analyzing learners is the cornerstone for instructional design process. Students’ readiness for e-learning was assessed in the present study as an example of learner analysis for a distance course in medical education master program. Materials and Methods: A census sample of 23 students applied for distance master program on medical education, completed the “Students’ E-Learning Readiness Scale” developed by Watkins, via email. The reliability and validity of the scale has been confirmed before. Average scores in total and 6 subscales were calculated. The score range was 1-5 and scores above 3 indicated good readiness. Data was interpreted using descriptive and non-parametric tests (Mann-Whitney U and Kruskal-Wallis). Results: Response rate was 100%. The students’ readiness scores in total and all subscales (“technology access”, “online skills and relationships”, “motivation”, “online audio/video”, “readiness for online discussions”, and “importance of e-learning to your success”) were above 3. Comparing different subscales, students’ mean scores in “motivation” and “internet discussion” subscales were less than others, although the difference was not significant. There were no significant gender differences in the readiness scores. Students who were academic staff had significantly higher scores than others in total and in “motivation” and “online skills and relationship” subscales. Conclusion: Good learners’ readiness, observed in the present study, may imply that the instructional designer can rely on e-learning strategies and build the course upon them. However, according to the slightly lower scores in “motivation” and “online discussion” subscales, it is recommended to stress more on strategies that improve these two components. To generalize the results, it is needed to test students’ readiness in more different degree programs. PMID:24524090

The aim of the present study was twofold: 1. to compare the efficacy of three antipsychotics (ziprasidone, olanzapine and perazine) in schizophrenia 2. to compare the improvement in cognitive functioning between groups treated with the three different neuroleptics. A total of 58 Caucasian patients diagnosed with paranoid schizophrenia were recruited into the study group. We used the Polish version of the CIDI (Composite International Diagnostic Interview) to obtain ICD-10 diagnoses. The intensity of psychopathological symptoms was examined using the PANSS. The patients were randomly assigned to treatment with perazine, olanzapine or ziprasidone administered as monotherapy for 3 months. The treatment efficacy was measured as a change in the PANSS (Positive and Negative Syndrome Scale) total score from baseline (T0) to 3 months (T1). The WCST (The Wisconsin Card Sorting Test) was used to measure working memory and executive functions in the evaluated patients. Wilcoxon's and Kruskal-Wallis tests were applied to compare changes in the PANSS scores between the treatment groups. To analyze the cognitive functions, Kruskal-Wallis test for the WCST parameters was used. The three antipsychotics similarly reduced the total PANSS score. The WCST parameters in the 3 groups of examined patients using the Kruskal-Wallis test revealed some differences between the three administered antipsychotics. Results suggest that the short-term efficacy of the atypical (olanzapine, ziprasidone) and typical (perazine) antipsychotic drugs did not differ. Based on the analysis, a conclusion can be drawn that the three neuroleptics provided similar improvements in cognitive functioning.

Purpose To develop a multidimensional scale to asses psychosocial beliefs-the Yellow Flag Questionnaire (YFQ)-aimed at guiding interventions for workers with chronic musculoskeletal (MSK) pain. Methods Phase 1 consisted of item selection based on literature search, item development and expert consensus rounds. In phase 2, items were reduced with calculating a quality-score per item, using structure equation modeling and confirmatory factor analysis on data from 666 workers. In phase 3, Cronbach's α, and Pearson correlations coefficients were computed to compare YFQ with disability, anxiety, depression and self-efficacy and the YFQ score based on data from 253 injured workers. Regressions of YFQ total score on disability, anxiety, depression and self-efficacy were calculated. Results After phase 1, the YFQ included 116 items and 15 domains. Further reductions of items in phase 2 by applying the item quality criteria reduced the total to 48 items. Phase factor analysis with structural equation modeling confirmed 32 items in seven domains: activity, work, emotions, harm & blame, diagnosis beliefs, co-morbidity and control. Cronbach α was 0.91 for the total score, between 0.49 and 0.81 for the 7 distinct scores of each domain, respectively. Correlations between YFQ total score ranged with disability, anxiety, depression and self-efficacy was .58, .66, .73, -.51, respectively. After controlling for age and gender the YFQ total score explained between R2 27% and R2 53% variance of disability, anxiety, depression and self-efficacy. Conclusions The YFQ, a multidimensional screening scale is recommended for use to assess psychosocial beliefs of workers with chronic MSK pain. Further evaluation of the measurement properties such as the test-retest reliability, responsiveness and prognostic validity is warranted.

Context:  Some healthy athletes report high levels of baseline concussion symptoms, which may be attributable to several factors (eg, illness, personality, somaticizing). However, the role of baseline symptoms in outcomes after sport-related concussion (SRC) has not been empirically examined. Objective:  To determine if athletes with high symptom scores at baseline performed worse than athletes without baseline symptoms on neurocognitive testing after SRC. Design:  Cohort study. Setting:  High school and collegiate athletic programs. Patients or Other Participants:  A total of 670 high school and collegiate athletes participated in the study. Participants were divided into groups with either no baseline symptoms (Postconcussion Symptom Scale [PCSS] score = 0, n = 247) or a high level of baseline symptoms (PCSS score > 18 [top 10% of sample], n = 68). Main Outcome Measure(s):  Participants were evaluated at baseline and 2 to 7 days after SRC with the Immediate Post-concussion Assessment and Cognitive Test and PCSS. Outcome measures were Immediate Post-concussion Assessment and Cognitive Test composite scores (verbal memory, visual memory, visual motor processing speed, and reaction time) and total symptom score on the PCSS. The groups were compared using repeated-measures analyses of variance with Bonferroni correction to assess interactions between group and time for symptoms and neurocognitive impairment. Results:  The no-symptoms group represented 38% of the original sample, whereas the high-symptoms group represented 11% of the sample. The high-symptoms group experienced a larger decline from preinjury to postinjury than the no-symptoms group in verbal (P = .03) and visual memory (P = .05). However, total concussion-symptom scores increased from preinjury to postinjury for the no-symptoms group (P = .001) but remained stable for the high-symptoms group. Conclusions:>  Reported baseline symptoms may help identify athletes at risk for worse outcomes after SRC. Clinicians should examine baseline symptom levels to better identify patients for earlier referral and treatment for their injury. Additional investigation of baseline symptoms is warranted to help delineate the type and severity of premorbid symptoms. PMID:26885702

Healthy Eating Index--2005 total and component scores for adults aged 20 and over: National Health and Nutrition Examination Survey, 2003-2004.

This report provides Healthy Eating Index-2005 (HEI-2005) scores for adults aged 20 and over, by sex, age groups, race and ethnicity, and level of education in the 2003-2004 National Health and Nutrition Examination Survey (NHANES 2003-2004). The analytic sample consisted of 4,448 adults aged 20 and over from NHANES 2003-2004. The Day 1 dietary recall was used to estimate the HEI-2005 scores. Food and nutrient intakes were assessed on a density basis. The population's mean usual HEI-2005 component and total scores were calculated using a population ratio method based on programs written by the U.S. Department of Agriculture's Center for Nutrition Policy and Promotion. A two-tailed t-test was used to test significant differences between sexes, age and race, and ethnic groups and levels of education. Statistical hypotheses were tested at the p < 0.05 level of significance using a t statistic. The t-value at 0.975 with 15 degrees of freedom was 2.131. The Bonferroni method of adjustment was used to adjust the critical value for the family of pairwise comparisons for age, race and ethnicity, and education. Adults were below the maximum standard for all the HEI-2005 component scores except for total grains and meat and beans. Females and the oldest age group were more successful in meeting the Dietary Guidelines for Americans 2005 recommendations for the fruit and vegetable components and discretionary calories, and had a slightly higher overall diet quality score than their counterparts. Adults with more than a high school education more closely complied with the recommendations for many of the components compared with those with less education. No one racial and ethnic group stood out as having the highest HEI-2005 scores across most of the components. These results demonstrate that adults continue to fall short in meeting the Dietary Guidelines for Americans 2005 recommendations, and that sociodemographic characteristics influence their food choices and overall diet quality.

Building research capacity in developing countries using cost-effective methods has been recognized as an important pillar for the production of a sound evidence base for decision-making in policy and practice. We assessed the effectiveness and cost-effectiveness of a research training course conducted using traditional methods as well as the video-teleconferencing (VTC) method in Pakistan. A 9-day epidemiology research training course was offered to physicians in Pakistan (92%) and Bangladesh (8%). The course was taught using (1) a traditional classroom face-to face (F2F) method at the Aga Khan University, Karachi, Pakistan, and (2) the VTC method at two medical institutions within Pakistan. In total, 40 participants were selected for the F2F group and 46 for the VTC group. Outcome parameters were assessed pre- and post-course (short-term) as well as after 1 year (long-term). Costs of conducting the training by both methods were also identified using cost-effectiveness analysis. The total study sample included 56 participants (F2F n =38, VTC n=18) for the short-term and 49 participants for the long-term assessment. After the end of the course (Day 9), mean post-test 1 scores showed significant improvement in both groups: 15.08 ± 1.75 in F2F (p=0.001) versus 13.122 ± 1.87 in VTC (p=0.001). Mean scores 1 year after the course (post-test 2) were lower than mean post-test 1 scores in both groups (13.42 ± 2.61 in F2F versus 12.31 ± 2.08 in VTC) but were higher than the baseline pretest scores. The total incremental cost per score gained was higher for the VTC group for both short-term (VTC incremental cost was $166/score gained) and long-term (VTC incremental cost was $458/ score gained) course effectiveness. The use of e-technologies in developing countries proves to be an effective way of building capacity and reducing the problems of brain drain. This initial study provides a foundation from which larger studies may be developed.

The study design was cross-cultural adaptation and investigation of reliability and validity of the Copenhagen Neck Functional Disability Scale (CNFDS). The aim of this study was to translate the CNFDS into Turkish language and assess its reliability and validity among patients with neck pain in Turkish population. The CNFDS is a reliable and valid evaluation instrument for disability, but there is no published the Turkish version of the CNFDS. One hundred one subjects who had chronic neck pain were included in this study. The CNFDS, Neck Pain and Disability Scale, and visual analogue scale were administered to all subjects. For investigating test-retest reliability, correlation between CNFDS scores, applied at 1-week interval, intraclass correlation coefficient score for test-retest reliability was 0.86 (95% confidence interval = 0.679-0.935). There was no difference between test-retest scores (P < 0.001). For investigating concurrent validity, correlation between total score of the CNFDS and the mean visual analogue scale was r = 0.73 (P < 0.001). Concurrent validity of the CNFDS was very good. For investigating construct validity, correlation between total score of the CNFDS and the Neck Pain and Disability Scale was r = 0.78 (P < 0.001). Construct validity of the CNFDS was also very good. Our results suggest that the Turkish version of the CNFDS is a reliable and valid instrument for Turkish people.

To determine whether a decline in cued recall is observable in the preclinical stage of Alzheimer disease (AD) in clinically normal older adults with elevated β-amyloid (Aβ) burden on PET imaging. Clinically normal older adults underwent baseline neuroimaging (PET to assess Aβ +/- status and MRI) and annual neuropsychological testing. Cox proportional hazards models were used to assess the relative risk of cued memory decline (drop of 1, 2, 3, or 4 points on the total score of the Free and Cued Selective Reminding Test) in relation to neuroimaging measures, functional status, age, sex, and education. A total of 276 older adults (Clinical Dementia Rating = 0, mean Mini-Mental State Examination score = 29 ± 1.06) were followed up for a mean of 3.6 ± 1.2 years. Despite the infrequency of cued memory decline (only 19% of participants scored ≤46/48 in total recall by year 3), Aβ + participants were 3.55 times (95% confidence interval = 1.77-7.12) more likely to exhibit decline in total recall (≤46/48) compared with their Aβ - peers. Furthermore, Aβ + participants who scored ≤46/48 had smaller hippocampal volumes ( t = 3.37, p = 0.001) and evidence of early functional decline, i.e., greater risk of progression to global Clinical Dementia Rating of 0.5 (χ 2 = 14.30, p < 0.001), compared with their Aβ + peers with intact total recall. Cued memory decline in healthy older adults may be particularly indicative of Aβ-related decline during the preclinical stage of AD and useful for identifying Aβ + clinically normal individuals at greatest risk of short-term clinical progression. © 2017 American Academy of Neurology.

Objective: To determine whether a decline in cued recall is observable in the preclinical stage of Alzheimer disease (AD) in clinically normal older adults with elevated β-amyloid (Aβ) burden on PET imaging. Methods: Clinically normal older adults underwent baseline neuroimaging (PET to assess Aβ+/− status and MRI) and annual neuropsychological testing. Cox proportional hazards models were used to assess the relative risk of cued memory decline (drop of 1, 2, 3, or 4 points on the total score of the Free and Cued Selective Reminding Test) in relation to neuroimaging measures, functional status, age, sex, and education. Results: A total of 276 older adults (Clinical Dementia Rating = 0, mean Mini-Mental State Examination score = 29 ± 1.06) were followed up for a mean of 3.6 ± 1.2 years. Despite the infrequency of cued memory decline (only 19% of participants scored ≤46/48 in total recall by year 3), Aβ+ participants were 3.55 times (95% confidence interval = 1.77–7.12) more likely to exhibit decline in total recall (≤46/48) compared with their Aβ− peers. Furthermore, Aβ+ participants who scored ≤46/48 had smaller hippocampal volumes (t = 3.37, p = 0.001) and evidence of early functional decline, i.e., greater risk of progression to global Clinical Dementia Rating of 0.5 (χ2 = 14.30, p < 0.001), compared with their Aβ+ peers with intact total recall. Conclusions: Cued memory decline in healthy older adults may be particularly indicative of Aβ-related decline during the preclinical stage of AD and useful for identifying Aβ+ clinically normal individuals at greatest risk of short-term clinical progression.

Objective To assess the nutritional quality of food packages offered in the Food Distribution Program on Indian Reservations (FDPIR) program using Healthy Eating Index-2010 (HEI-2010). Design Data were collected from the list of the food products provided by the United States Department of Agriculture’s Food and Nutrition Handbook 501 for FDPIR. Nutritional quality was measured through a cross-sectional analysis of five randomly selected food packages offered through FDPIR. HEI-2010 component and total scores were calculated for each food package. Analysis of variance and t-tests assessed significant differences between food packages and HEI-2010 maximum scores, respectively. Setting This study took place in the United States. Subjects Study units included food products offered through FDPIR. Results The mean total HEI-2010 score for the combined FDPIR food packages was significantly lower than the total HEI-2010 maximum score of 100 (66.38, SD=11.60; p<0.01). Mean scores for total fruit (3.52, SD=0.73; p<0.05), total vegetables (2.58, SD=0.15; p<0.001), greens and beans (0.92, SD=1.00; p<0.001), dairy (5.12, SD=0.63; p<0.001), total protein foods (4.14, SD=0.56; p<0.05), and refined grains (3.04, SD=2.90; p<0.001) were all significantly lower than the maximum values. Conclusions The FDPIR food package HEI-2010 score was notably higher than other federal food assistance and nutrition programs. Study findings highlight opportunities for the FDPIR to modify its offerings to best support lifestyles towards prevention of diet-related chronic disease. PMID:26298513

To assess cognitive performance and psychosocial functioning in patients with bipolar disorder (BD), in unaffected siblings, and in healthy controls. Subjects were patients with BD (n=36), unaffected siblings (n=35), and healthy controls (n=44). Psychosocial functioning was accessed using the Functioning Assessment Short Test (FAST). A sub-group of patients with BD (n=21), unaffected siblings (n=14), and healthy controls (n=22) also underwent a battery of neuropsychological tests: California Verbal Learning Test (CVLT), Stroop Color and Word Test, and Wisconsin Card Sorting Test (WCST). Clinical and sociodemographic characteristics were analyzed using one-way analysis of variance or the chi-square test; multivariate analysis of covariance was used to examine differences in neuropsychological variables. Patients with BD showed higher FAST total scores (23.90±11.35) than healthy controls (5.86±5.47; p < 0.001) and siblings (12.60±11.83; p 0.001). Siblings and healthy controls also showed statistically significant differences in FAST total scores (p = 0.008). Patients performed worse than healthy controls on all CVLT sub-tests (p < 0.030) and in the number of correctly completed categories on WCST (p = 0.030). Siblings did not differ from healthy controls in cognitive tests. Unaffected siblings of patients with BD may show poorer functional performance compared to healthy controls. FAST scores may contribute to the development of markers of vulnerability and endophenotypic traits in at-risk populations.

To compare the effectiveness of abrasive component (perlite/calcium carbonate) and enzymatic component (papain and bromelain) of whitening toothpaste in removal of extrinsic stains. This study is a randomized, triple blind and parallel group study in which 90 subjects aged 18-40 years were included. At baseline, stains scores were assessed by Macpherson's modification of Lobene Stain Index and subjects were randomly assigned to two groups with 45 subjects in each. Group 1 used whitening toothpaste with enzymatic action and group 2 with abrasive action. After 1 month, stain scores were assessed for the effectiveness of the two toothpastes and 2 months later to check the stain prevention efficacy. Wilcoxson's test was used to compare between baseline 1 and 2 months stain scores, and Mann-Witney U-test was applied for intragroup comparison. The mean baseline total stain score for the subjects allocated to the enzymatic toothpaste was 37.24 ± 2.11 which reduced to 30.77 ± 2.48 in 1 month, and for the abrasive paste, total stain reduced from 35.08 ± 2.96 to 32.89 ± 1.95. The reductions in total stain scores with both the pastes were significant compared with baseline stain scores (at 1 month Group 1, P = 0.0233 and Group 2, P = 0.0324; at 2 months, Group 1 P = 0.0356). Both the toothpastes proved to be equally good in removal of extrinsic stains; however, the enzymatic paste showed better results as compared to abrasive toothpaste. Whitening toothpaste with abrasive action and enzymatic action are equally effective in removal of extrinsic stains; however, whitening toothpaste with abrasive action needs to be used with caution. © 2014 John Wiley & Sons A/S.

Balance deficits are common after total knee arthroplasty (TKA); however the responsiveness of commonly used balance measurement tools has not been well defined. The objective of this prospective study was to compare the internal and external responsiveness of four measurement tools in assessing recovery of balance function following TKA. A total of 134 individuals with TKA (95 women; age: 66.3±6.6years) completed the Balance Evaluation Systems Test (BESTest), Mini-BESTest, Brief-BESTest, and Berg Balance Scale (BBS) at 2, 4, 8, 12, and 24 weeks post-TKA. The Functional Gait Assessment (FGA) served as the anchor measure, and was also measured across these time points. Internal responsiveness was indicated by the standardized response mean (SRM), while external responsiveness was reflected by the degree of association of the changes of balance scores with those of FGA. The SRM ranged from 0.60-1.14 for the BESTest, 0.40-0.94 for the Mini-BESTest, 0.27-0.91 for the Brief-BESTest, and 0.19-0.70 for the BBS, over time. The change in BESTest and Mini-BESTest scores predicted the change in the FGA scores across all time periods, except for the Mini-BESTest between weeks 12-24, accounting for 13-27%, and 12-24% of the variance, respectively. The Brief-BESTest scores only predicted FGA scores between the weeks 2-4 (R 2 =20%). The changes in BBS scores were not associated with the FGA. The BESTest is the most responsive in measuring recovery of balance among individuals with TKA. The Mini-BESTest is a reasonable option during time constraints. Copyright © 2017.

We prepared a cross-cultural adaptation of the Behcet's Syndrome Activity Scale (BSAS) and evaluated its reliability and validity in Korea. Fifty patients with Behcet's disease (BD) who attended the Rheumatology Clinic of Gachon University Gil Medical Center were included in this study. The first BSAS questionnaire was administered at each clinic visit, and the second questionnaire was completed at home within 24 hours of the visit. A Behcet's Disease Current Activity Form (BDCAF) and a Behcet's Disease Quality of Life (BDQOL) form were also given to patients. The test-retest reliability was analyzed by intraclass correlation coefficients (ICC). To assess the validity, the total BSAS score was compared with the BDCAF score, the patient/physician global assessment, and the BDQOL by Spearman rank correlation. Twelve males and 38 females were enrolled. The mean age was 48.5 years and the mean disease duration was 6.7 years. Thirty-eight patients (76.0%) returned the questionnaire by mail. For the test-retest reliability, the two assessments were significantly correlated on all 10 items of the BSAS questionnaire (p < 0.05) and the total BSAS score (ICC, 0.925; p < 0.001). The total BSAS score was statistically correlated with the BDQOL, BDCAF, and patient/physician global assessment (p < 0.01). The Korean version of BSAS is a reliable and valid instrument to measure BD activity.

To carry out a modified replication of the study performed by Kulp and Sortor evaluating the clinical value of the information provided by Beery's visual-motor supplemental tests of Visual Perception (VP) and Motor Coordination (MC) in normally developed children. The objectives were to (a) estimate the correlations among the three tests scores; (b) assess the predictive power of the VP and MC scores in explaining the variance in Visual-Motor Integration (VMI) scores; and (c) examine whether poor performance on the VMI is related to poor performance on VP or MC. METHODS.: A convenience sample of 71 children ages 4 and 5 years (M = 4.62 +/- 0.43) participated in the study. The supplemental tests significantly (F = 9.59; dF = 2; p < or = 0. 001) explained 22% of the variance in VMI performance. Only VP was significantly related to VMI (beta = 0.39; T = 3.49) accounting for the total amount of explained variance. Using the study population norms, 11 children (16% of total sample) did poorly on the VMI; of those 11, 73% did poorly on the VP, and none did poorly on the MC. None of these 11 did poorly on both the VP and MC. Nine percent of total sample who did poorly on the VP performed within the norm on the VMI. Thirteen percent who performed poorly on the MC performed within the norm on the VMI. Using the VMI published norms, 14 children (20% of total sample) who did poorly on the VP performed within the norm on the VMI. Forty-eight percent who did poorly on MC performed within the norm on the VMI. Findings supported Kulp and Sortor's conclusions that each area should be individually evaluated during visual-perceptual assessment of children regardless of performance on the VMI.

This study aims to evaluate the effect of laparoscopic skills courses on the knowledge of laparoscopic equipment. A knowledge test on laparoscopic equipment was developed, and participants of 3 separate basic laparoscopic skills courses in the Netherlands completed the test at the beginning and end of these courses. All lectures and demonstrations during the courses were recorded on video to assess the matching of its contents with the items in the test. As a reference, the test was also completed by a group of laparoscopic experts by e-mail. In total, 36 participants (64.3%) completed both the pretest and posttest. Overall, the mean test score improved from 60.4% of the maximum possible score for the pretest to 68.4% for the posttest. There were no significant differences in test scores between the 3 separate courses. However, the actual content varied among the courses. The correspondence of the test items with the course content varied from 47% to 69%. Although 30% of the participants had already received training for laparoscopic equipment in their own hospital, 92.5% wanted to receive more training. 28 experts completed the test with a mean score of 75.7%, which was significantly better than the posttest score of the course participants. The laparoscopic skills courses evaluated in this study had a modest positive effect on the acquisition of knowledge about laparoscopic equipment. Variance exists among their contents.

Test anxiety is well known among medical students. However, little is known about test anxiety produced by different components of exam individually. This study aimed to stratify varying levels of test anxiety provoked by each exam modality and to explore the students perceptions about confounding factors. A self-administered questionnaire was administered to medical students. The instrument contained four main themes; lifestyle, psychological and specific factors of information needs, learning styles, and perceived difficulty level of each assessment tool. A highest test anxiety score of 5 was ranked for "not scheduling available time" and "insufficient exercise" by 28.8 and 28.3% students, respectively. For "irrational thoughts about exam" and "fear to fail", a highest test anxiety score of 5 was scored by 28.8 and 25.7% students, respectively. The highest total anxiety score of 1255 was recorded for long case exam, followed by 975 for examiner-based objective structured clinical examination. Excessive course load and course not well covered by faculty were thought to be the main confounding factors. The examiner-based assessment modalities induced high test anxiety. Faculty is urged to cover core contents within stipulated time and to rigorously reform and update existing curricula to prepare relevant course material.

We sought to compare age-related performance on the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) across the adult lifespan in an asymptomatic, presumably normal, sample. The MMSE is the most commonly used brief cognitive screening test; however, the MoCA may be better at detecting early cognitive dysfunction. We gave the MMSE and MoCA to 254 community-dwelling participants ranging in age from 20 to 89, stratified by decade, and we compared their scores using the Wilcoxon signed rank test. For the total sample, the MMSE and MoCA differed significantly in total scores as well as in visuospatial, language, and memory domains (for all of these scores, P<0.001). Mean MMSE scores declined only modestly across the decades; mean MoCA scores declined more dramatically. There were no consistent domain differences between the MMSE and MoCA during the third and fourth decades; however, significant differences in memory (P<0.05) and language (P<0.001) emerged in the fifth through ninth decades. We conclude that the MoCA may be a better detector of age-related decrements in cognitive performance than the MMSE, as shown in this community-dwelling adult population.

Pharmacogenomic Approaches for Automated Medication Risk Assessment in People with Polypharmacy

Abstract Medication regimen may be optimized based on individual drug efficacy identified by pharmacogenomic testing. However, majority of current pharmacogenomic decision support tools provide assessment only of single drug-gene interactions without taking into account complex drug-drug and drug-drug-gene interactions which are prevalent in people with polypharmacy and can result in adverse drug events or insufficient drug efficacy. The main objective of this project was to develop comprehensive pharmacogenomic decision support for medication risk assessment in people with polypharmacy that simultaneously accounts for multiple drug and gene effects. To achieve this goal, the project addressed two aims: (1) development of comprehensive knowledge repository of actionable pharmacogenes; (2) introduction of scoring approaches reflecting potential adverse effect risk levels of complex medication regimens accounting for pharmacogenomic polymorphisms and multiple drug metabolizing pathways. After pharmacogenomic knowledge repository was introduced, a scoring algorithm has been built and pilot-tested using a limited data set. The resulting total risk score for frequently hospitalized older adults with polypharmacy (72.04±17.84) was statistically significantly different (p<0.05) from the total risk score for older adults with polypharmacy with low hospitalization rate (8.98±2.37). An initial prototype assessment demonstrated feasibility of our approach and identified steps for improving risk scoring algorithms.

To characterize student performance on the Pharmacy Curriculum Outcomes Assessment (PCOA) and to determine the significance of specific admissions criteria and pharmacy school performance to predict student performance on the PCOA during the first through third professional years. Multivariate linear regression models were developed to study the relationships between various independent variables and students' PCOA total scores during the first through third professional years. To date, four cohorts have successfully taken the PCOA examination. Results indicate that the Pharmacy College Admissions Test (PCAT), the Health Science Reasoning Test (HSRT), and cumulative pharmacy grade point average were the only consistent significant predictors of higher PCOA total scores across all students who have taken the exam at our school of pharmacy. The school should examine and clarify the role of PCOA within its curricular assessment program. Results suggest that certain admissions criteria and performance in pharmacy school are associated with higher PCOA scores. Copyright © 2016 Elsevier Inc. All rights reserved.

Spatial abilities, Earth science conceptual understanding, and psychological gender of university non-science majors

NASA Astrophysics Data System (ADS)

Black, Alice A. (Jill)

Research has shown the presence of many Earth science misconceptions and conceptual difficulties that may impede concept understanding, and has also identified a number of categories of spatial ability. Although spatial ability has been linked to high performance in science, some researchers believe it has been overlooked in traditional education. Evidence exists that spatial ability can be improved. This correlational study investigated the relationship among Earth science conceptual understanding, three types of spatial ability, and psychological gender, a self-classification that reflects socially-accepted personality and gender traits. A test of Earth science concept understanding, the Earth Science Concepts (ESC) test, was developed and field tested from 2001 to 2003 in 15 sections of university classes. Criterion validity was .60, significant at the .01 level. Spearman/Brown reliability was .74 and Kuder/Richardson reliability was .63. The Purdue Visualization of Rotations (PVOR) (mental rotation), the Group Embedded Figures Test (GEFT) (spatial perception), the Differential Aptitude Test: Space Relations (DAT) (spatial visualization), and the Bem Inventory (BI) (psychological gender) were administered to 97 non-major university students enrolled in undergraduate science classes. Spearman correlations revealed moderately significant correlations at the .01 level between ESC scores and each of the three spatial ability test scores. Stepwise regression analysis indicated that PVOR scores were the best predictor of ESC scores, and showed that spatial ability scores accounted for 27% of the total variation in ESC scores. Spatial test scores were moderately or weakly correlated with each other. No significant correlations were found among BI scores and other test scores. Scantron difficulty analysis of ESC items produced difficulty ratings ranging from 33.04 to 96.43, indicating the percentage of students who answered incorrectly. Mean score on the ESC was 34%, indicating that the non-majors tested exhibited many Earth science misconceptions and conceptual difficulties. A number of significant results were found when independent t-tests and correlations were conducted among test scores and demographic variables. The number of previous university Earth science courses was significantly related to ESC scores. Preservice elementary/middle majors differed significantly in several ways from other non-majors, and several earlier results were not supported. Results of this study indicate that an important opportunity may exist to improve Earth science conceptual understanding by focusing on spatial ability, a cognitive ability that has heretofore not been directly addressed in schools.

Abstract Objective. The aim was to evaluate the reliability, validity and responsiveness to change of the Gout Impact Scale (GIS), a disease-specific measure of patient-reported outcomes, in a multicentre longitudinal prospective cohort of gout patients. Methods. Subjects completed the GIS, a 24-item instrument with five scales: Concern Overall, Medication Side Effects, Unmet Treatment Need, Well-Being during Attack, and Concern Over Attack. The total GIS score was calculated by averaging the GIS scale scores. HAQ-Disability Index (HAQ-DI), Short Form (SF)-36 physical and mental component summaries (PCS and MCS) and physician and patient gout severity assessments were also completed. Reliability was assessed with Cronbach’s α. Baseline GIS scores were compared in subjects with and without gout attacks in the past 3 months using Wilcoxon rank sum tests. Multivariate linear regression was used to evaluate predictors of total GIS. Pearson’s correlation coefficients 0.24–0.36 were considered moderate and >0.37 considered large. The effect size for responsiveness to change was interpreted as follows: 0.20–0.49 small, 0.50–0.79 medium and >0.79 large. Results. In 147 subjects, reliability was acceptable for total GIS (0.93) and all GIS scales (0.82–0.94) except Medication Side Effects and Unmet Treatment Need. Total GIS and all scales except Medication Side Effects discriminated between subjects with and without recent gout attacks (P < 0.05). Total GIS showed moderate-to-large correlations with HAQ-DI, SF-36 PCS and MCS (0.33–0.46). Improvement in total GIS tracked with improved physician and patient severity scores. Worsening physician severity score and recent gout attack predicted worsening total GIS. Conclusion. Total GIS score is reliable, valid and responsive to change in patients with gout, and differentiates between subjects with and without recent gout attacks. PMID:26888852

To characterize defects in color vision in patients with choroideremia. Prospective cohort study. Thirty patients with choroideremia (41 eyes) and 10 age-matched male controls (19 eyes) with visual acuity of ≥6/36 attending outpatient clinics in Oxford Eye Hospital underwent color vision testing with the Farnsworth-Munsell 100 hue test, visual acuity testing, and autofluorescence imaging. To exclude changes caused by degeneration of the fovea, a subgroup of 14 patients with a visual acuity ≥6/6 was analyzed. Calculated color vision total error scores were compared between the groups and related to a range of factors using a random-effects model. Mean color vision total error scores were 120 (95% confidence interval [CI] 92, 156) in the ≥6/6 choroideremia group, 206 (95% CI 161, 266) in the <6/6 visual acuity choroideremia group, and 47 (95% CI 32, 69) in the control group. Covariate analysis showed a significant difference in color vision total error score between the groups (P < .001 between each group). Patients with choroideremia have a functional defect in color vision compared with age-matched controls. The color vision defect deteriorates as the degeneration encroaches on the fovea. The presence of an early functional defect in color vision provides a useful biomarker against which to assess successful gene transfer in gene therapy trials. Copyright © 2015 Elsevier Inc.

To analyze the relationship between visuospatial ability and simulated laparoscopy performed by consultants in obstetrics and gynecology (OBGYN). This was a prospective cohort study carried out at two community hospitals in Sweden. Thirteen consultants in obstetrics and gynecology were included. They had previously independently performed 10-100 advanced laparoscopies. Participants were tested for visuospatial ability by the Mental Rotations Test version A (MRT-A). After a familiarization session and standardized instruction, all participants subsequently conducted three consecutive virtual tubal occlusions followed by three virtual salpingectomies. Performance in the simulator was measured by Total Time, Score and Ovarian Diathermy Damage. Linear regression was used to analyze the relationship between visuospatial ability and simulated laparoscopic performance. The learning curves in the simulator were assessed in order to interpret the relationship with the visuospatial ability. Visuospatial ability correlated with Total Time (r=-0.62; p=0.03) and Score (r=0.57; p=0.05) in the medium level of the virtual tubal occlusion. In the technically more advanced virtual salpingectomy the visuospatial ability correlated with Total Time (r=-0.64; p=0.02), Ovarian Diathermy Damage (r=-0.65; p=0.02) and with overall Score (r=0.64; p=0.02). Visuospatial ability appears to be related to the performance of gynecological laparoscopic procedures in a simulator. Testing visuospatial ability might be helpful when designing individual training programs. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

The effect of cyberbullying accompanied by traditional bullying on mental health has been less studied. In this study, the frequency, co-occurrence, and the relationship to psychiatric symptoms of traditional bullying and cyberbullying among bullies and victims are examined. All of the high schools in the province of Mus, Turkey were stratified according to Placement Test for High Schools admission points for 2014-2015. By choosing schools using simple random sampling, 1276 students were reached. Students were given the Brief Symptom Inventory and three separate scale assessments: peer bullying rating, cybervictimization, and cyberbullying scales. High scores in all subscale scores of bullying and victimization were significantly related to higher depression, anxiety, low self-esteem, somatization, and hostility scores. For people who were exposed to cyberbullying in addition to traditional bullying, the severity of the psychiatric symptoms was significantly higher. For all psychiatric symptoms, major predictors were gender, total victimization score, and total cybervictimization score. Moreover, the bullying total score was among the predictors of low self-esteem and hostility. Cybervictimization and cyberbullying occur less often than traditional bullying and victimization, but people who were exposed to or performed cyberbullying were also exposed to or performed traditional bullying. The addition of cyberbullying to traditional bullying is associated with more intense psychiatric symptoms. © 2016 Japan Pediatric Society.

INTRODUCTION: Patient satisfaction becomes more important in our modern health care system. The assessment of satisfaction is difficult because it is a multifactorial item for which no golden standard exists. One of the potential methods of measuring satisfaction is by using the well-known visual analogue scale (VAS). In this study, we validated VAS for satisfaction. PATIENT AND METHODS: In this prospective study, we studied 147 patients (153 hips). The construct validity was measured using the Spearman correlation test that compares the satisfaction VAS with the Harris hip score, pain VAS at rest and during activity, Oxford hip score, Short Form 36 and Western Ontario McMaster Universities Osteoarthritis Index. The reliability was tested using the intra-class coefficient. RESULTS: The Pearson correlation test showed correlations in the range of 0.40-0.80. The satisfaction VAS had a high correlation between the pain VAS and Oxford hip score, which could mean that pain is one of the most important factors in patient satisfaction. The intra-class coefficient was 0.95. CONCLUSIONS: There is a moderate to mark degree of correlation between the satisfaction VAS and the currently available subjective and objective scoring systems. The intra-class coefficient of 0.95 indicates an excellent test-retest reliability. The VAS satisfaction is a simple instrument to quantify the satisfaction of a patient after total hip arthroplasty. In this study, we showed that the satisfaction VAS has a good validity and reliability.

Our study aimed to determine whether the consideration of socio-demographic features improves the prediction of Alzheimer's dementia (AD) at 5 years when using the Free and Cued Selective Reminding Test (FCSRT) in the general older population. Our analyses focused on 2558 subjects from the prospective Three-City Study, a cohort of community-dwelling individuals aged 65 years and over, with FCSRT scores. Four "residual scores" and "risk scores" were built that included the FCSRT scores and socio-demographic variables. The predictive performance of crude, residual and risk scores was analyzed by comparing the areas under the ROC curve (AUC). In total, 1750 subjects were seen 5 years after completing the FCSRT. AD was diagnosed in 116 of them. Compared with the crude free-recall score, the predictive performances of the residual score and of the risk score were not significantly improved (AUC: 0.83 vs 0.82 and 0.88 vs 0.89 respectively). Using socio-demographic features in addition to the FCSRT does not improve its predictive performance for dementia or AD.

Supermarkets use sales circulars to highlight specific foods, usually at reduced prices. Resulting purchases help form the set of available foods within households from which individuals and families make choices about what to eat. The purposes of this study were to determine how closely foods featured in weekly supermarket sales circulars conform to dietary guidance and how diet quality compares with that of the US population's intakes. Food and beverage items (n=9,149) in 52 weekly sales circulars from a small Midwestern grocery chain in 2009 were coded to obtain food group and nutrient and energy content. Healthy Eating Index-2010 (HEI-2010) total and component scores were calculated using algorithms developed by the National Cancer Institute. HEI-2010 scores for the US population aged 2+ years were estimated using data from the 2009-2010 National Health and Nutrition Examination Survey. HEI-2010 scores of circulars and population intakes were compared using Student's t tests. Mean total (42.8 of 100) HEI-2010 scores of circulars were lower than that of the US population (55.4; P<0.001). Among individual components, Total Protein Foods was the only one for which 100% of the maximum score was met by both circulars and the population. The scores were also similar between the circulars and population for Whole Grains (22%; P=0.81) and Seafood and Plant Proteins (70% to 74%; P=0.33). Circular scores were lower than those of the population for Total and Whole Fruits, Total Vegetables and Greens and Beans, Dairy, Sodium, and Empty Calories (P<0.001); they were higher only for Fatty Acids (P=0.006) and Refined Grains (P<0.001). HEI-2010 total scores for these sales circulars were even lower than US population scores, which have been shown repeatedly to reflect low diet quality. Supermarkets could support improvements in consumer diets by weekly featuring foods that are more in concordance with food and nutrient recommendations.

Pawlukiewicz, Alec; Yengo-Kahn, Aaron M; Solomon, Gary

2017-10-01

Baseline neurocognitive assessment plays a critical role in return-to-play decision making following sport-related concussions. Prior studies have assessed the effect of a variety of modifying factors on neurocognitive baseline test scores. However, relatively little investigation has been conducted regarding the effect of pretest exercise on baseline testing. The aim of our investigation was to determine the effect of pretest exercise on baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) scores in adolescent and young adult athletes. We hypothesized that athletes undergoing self-reported strenuous exercise within 3 hours of baseline testing would perform more poorly on neurocognitive metrics and would report a greater number of symptoms than those who had not completed such exercise. Cross-sectional study; Level of evidence, 3. The ImPACT records of 18,245 adolescent and young adult athletes were retrospectively analyzed. After application of inclusion and exclusion criteria, participants were dichotomized into groups based on a positive (n = 664) or negative (n = 6609) self-reported history of strenuous exercise within 3 hours of the baseline test. Participants with a positive history of exercise were then randomly matched, based on age, sex, education level, concussion history, and hours of sleep prior to testing, on a 1:2 basis with individuals who had reported no pretest exercise. The baseline ImPACT composite scores of the 2 groups were then compared. Significant differences were observed for the ImPACT composite scores of verbal memory, visual memory, reaction time, and impulse control as well as for the total symptom score. No significant between-group difference was detected for the visual motor composite score. Furthermore, pretest exercise was associated with a significant increase in the overall frequency of invalid test results. Our results suggest a statistically significant difference in ImPACT composite scores between individuals who report strenuous exercise prior to baseline testing compared with those who do not. Since return-to-play decision making often involves documentation of return to neurocognitive baseline, the baseline test scores must be valid and accurate. As a result, we recommend standardization of baseline testing such that no strenuous exercise takes place 3 hours prior to test administration.

Cumulative trauma disorders in the upper extremities: reliability of the postural and repetitive risk-factors index.

1997-08-01

This study addresses test-retest reliability of the Postural and Repetitive Risk-Factors Index (PRRI) for work-related upper body injuries. This assessment was developed by the present authors. A repeated measures design was used to assess the test-retest reliability of a videotaped work-site assessment of subjects' movements. Ten heavy users of video display terminals (VDTs) from a local banking industry participated in the study. The 10 subjects' movements were videotaped for 2 hours on each of 2 separate days, while working on-site at their VDTs. The videotaped assessment, which utilized known postural risk factors for developing musculoskeletal disorder, pain, and discomfort in heavy VDT users (ie, repetitiveness, awkward and static postures, and contraction time), was called the PRRI. The videotaped movement assessments were subsequently analyzed in 15-minute sessions (five sessions per 2-hour videotape, which produced a total of 10 sessions over the 2 testing days), and each session was chosen randomly from the videotape. The subjects' movements were given a postural risk score according to the criteria in the PRRI. Each subject was therefore tested a total of 10 times (ie, 10 sessions), over two days. The maximum PRRI score for both sides of the body was 216 points. Reliability coefficients (RCs) for the PRRI scores were calculated, and the reliability of any one session met the minimum criterion for excellent reliability, which was .75. A two-way analysis of variance (ANOVA) confirmed that there was no statistically significant difference between sessions (p < .05). Calculations using the standard error of measurement (SEM) indicated that an individual tested once, on one day and with a PRRI score of 25, required a change of at least 8 points in order to be confident that a true change in score had occurred. The significant results from the reliability tests indicated that the PRRI was a reliable measurement tool that could be used by occupational health practitioners on the job site.

Assessment of general anxiety in patients with breast disease and breast cancer using the Spielberger STAI self evaluation test: a prospective case-control study in Finland.

Trait anxiety (T-Anxiety) was assessed using the subscale from the Spielberger State-Trait Anxiety Inventory test (STAI form Y-2), with statements refering to how a person generally feels, and a higher total score reflecting a higher T-Anxiety. To the authors' knowledge, the associations between the STAI test and the risk of breast cancer (BC) are rarely considered together in a prospective study. In an extension of the Kuopio Breast Cancer Study 115 women with breast symptoms were evaluated for anxiety using the STAI form Y-2 test before any diagnostic procedures were carried out. The clinical examination and biopsy showed BC in 34 patients, benign breast disease (BBD) in 53 patients and 28 individuals were shown to be healthy study subjects (HSS). There was a trend for the HSS women to have less severe anxiety in the STAI test (1/28 patients, 3.6%) than those in the BBD (7/53 patients, 13.2%) and BC groups (4/34 patients, 11.8%). The subjects in the HSS group reported being significantly more happy in the STAI test (STAI mean score, 1.54) than the BBD group (STAI mean score, 1.98) and the BC group (STAI mean score, 2.00) (p=0.01). The subjects in the HSS group also reported being more content in the STAI test (STAI mean score, 1.68) than the BBD group (STAI mean score, 1.87) and the BC group (STAI mean score, 1.97). Patients with BC and BBD tend to have more unhappy and uncontent feelings, but no specific link between the STAI test (form Y-2) and breast cancer risk is supported.

A double-blind randomized clinical trial was performed comparing the therapeutic effects of Actovegin versus placebo in elderly patients with organic brain syndrome. In addition to the necessary basic internal medicine therapy, 40 geriatric patients received dialy intravenous infusions of 250 ml Actovegin 20% p.i., and 20 patients received 250 ml 0.9% saline solution as placebo over a period of four weeks. Of the patient sample, 58% were hospitalized for simple dementia (ICD-9: 290.0) and 42% due to senile dementia with depressive or paranoid symptoms (ICD-9: 290.2). Based on the Syndrome Short Test (SKT) and the Sandoz Clinical Assessment Geriatric Scale (SCAG) score, the patients suffered from mild to moderate dementia. The therapeutic effect on the total SCAG score and the Clinical Global Impression (CGI) were the primary study variables. The scores for the SCAG subscales and the SKT score served as secondary variables. The mean total SCAG score in the drug group decreased from 56.3 at the start of therapy to 36.3 points at the end of therapy, and in the placebo group the total score went from 61.2 to 52.0 (p < 0.01). The CGI showed that with Actovegin, 70% of the patients experienced "distinct improvement" or "improvement" compared to only 35% with such results in the placebo group. The SCAG subscales and the total SKT score also demonstrated the superior effects of Actovegin compared to placebo. Moreover, the therapy group treated with Actovegin showed greater improvements in social behavior and mental performance than did the placebo group.(ABSTRACT TRUNCATED AT 250 WORDS)

Purpose: Levetiracetam-treated patients commonly report daytime drowsiness, fatique, asthenia and decreasing of motor activity. However the origin of these reported side effects are still debated, we aimed to clarify effect of levetiracetam on sleep. Therefore this prospective study was conducted to evaluate the effects of levetiracetam on motor activity, amount and continuity of sleep and napping. Methods: Various tests were performed on twenty two patients treated with levetiracetam (10 monotherapy, 12 add-on therapy) at least three days before the initiation of treatment, and consecutively for five to eight days at the third week of treatment. These tests included sleep logs, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Modified Maintenance of Wakefulness Test and actimetric measurements. In order to evaluate the sleep behavior of these patients the following sleep parameters were estimated: bedtime, wake-up time, sleep-onset time, sleep-offset time, sleep latency, total sleep time, wake time after sleep onset, fragmentation index, total activity score, nap episodes, total nap duration and sleep efficiency. Twenty members of staff from our hospital (Doctor, nurse, secretary, civil servant etc.) were evaluated as control subjects in the study. Results: After three-week treatment with levetiracetam (in particular with add-on therapy), Epworth Sleepiness Scale scores, napping episodes and total nap durations increased and sleep latencies decreased. While durations of Modified Maintenance of Wakefulness Test and total activity scores decreased. However the total sleep time and the sleep efficiency did not show any difference from the pre-treatment values. Conclusions: Our results suggest that levetiracetam leads to drowsiness by decreasing the daily motor activity and increasing the naps; however this agent does not have any major effects on total sleep time and sleep efficiency during night. Actimetric analyses give information about continuity of sleep and sleep/wake states however does not give satisfactory information about architecture of sleep. In order to determine the effects of levetiracetam on the sleep architecture we need similiar protocol studies by full night polysomnography. PMID:17726245

To assess the oral health-related quality of life (OHRQoL) of patients provided with mandibular implant fixed partial prostheses (IFPP) for rehabilitation of two adjacent missing posterior teeth and complete denture patients provided with mandibular implant-supported overdenture (ISOD). The response to change in OHRQoL with implant prostheses was additionally compared. In this prospective study, 20 IFPP (mean age 47.0; SD 12.9 years) and 28 ISOD (mean age 61.5; SD 9.1 years) patients received 2 mandibular implants. Metal ceramic nonsplinted fixed prostheses were provided in IFPP group, while in ISOD group, the mandibular overdentures were retained by nonsplinted attachments. Patients rated their oral health-related quality of life using OHIP-14 Malaysian version at baseline (T0), 2-3 months (T1) and 1 year (T2) postimplant treatment. Mean OHIP-14 for total and domain scores between groups and intervals was analysed using repeated-measures ANOVA and t-test. Mann-Whitney and Wilcoxon signed-rank tests were used for the comparison of mean score change and effect size, while the association between pre- and post-treatment scores was determined using multivariate linear regression modelling. The total OHIP and domain scores before implant treatment were significantly higher (lower OHRQoL) in IFPP than in ISOD groups, except for physical pain where this domain showed similar impact in both groups. Postimplant scores between groups at T1 and T2 showed no significant difference. The mean score changes at T0-T1 and T0-T2 for total OHIP-14 and domains were significantly greater in IFPP except in the domains of physical pain and disability which showed no difference. Large effect size (ES) was observed for total OHIP-14 in IFPP while moderate in ISOD. Improved OHRQoL was dependent on the treatment group and pretreatment score. Improvement in OHRQoL occurred following both mandibular implant-supported overdentures and implant fixed partial prostheses. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Theory of mind and its relation to schizotypy.

PubMed

Pickup, Graham J

2006-03-01

Frith (1992) suggested that many psychotic symptoms are associated with impaired theory of mind (ToM), the ability to represent the mental states of others. Langdon and Coltheart (1999) found an association in a nonclinical adult population between schizotypal traits and poorer ToM on a picture-sequencing task. The present study attempted to replicate and extend this finding using a ToM story task. A total of 62 nonclinical individuals completed a schizotypy questionnaire (the Oxford-Liverpool Inventory of Feelings and Experiences; O-LIFE) and a set of ToM stories. Matched "physical" control stories were administered to control for general reasoning ability. Executive function and current verbal IQ were assessed using the Cognitive Estimates Test and the Quick Test, respectively. Schizotypal traits analogous to positive symptoms of schizophrenia (UE scale of the O-LIFE) predicted poorer scores on the ToM task, but were unrelated to scores on physical stories. Individuals with high scores for total schizotypy on the O-LIFE did not differ in ToM from those with low total scores. There was no association between poorer ToM and schizotypal traits analogous to the "behavioural signs" of schizophrenia. Executive function and verbal IQ did not significantly predict story scores. Positive schizotypal traits in the normal population are associated with subtle impairments in ToM, independent of reasoning ability, executive function, or verbal IQ. A strong association between poor ToM and "behavioural signs" may only appear in studies of schizophrenic patients, and not in studies of nonclinical individuals. The findings are discussed in relation to Frith's (1992) cognitive neuropsychological model of schizophrenia.

Increasing focus on patient safety makes it important to ensure surgical competency among surgeons before operating on patients. The objective was to gather validity evidence for a virtual-reality simulator test for robotic surgical skills and evaluate its potential as a training tool. Surgeons with varying experience in robotic surgery were recruited: novices (zero procedures), intermediates (1-50), experienced (> 50). Five experienced surgeons rated five exercises on the da Vinci Skills Simulator. Participants were tested using the five exercises. Participants were invited back 3 times and completed a total of 10 attempts per exercise. The outcome was the average simulator performance score for the 5 exercises. 32 participants from 5 surgical specialties were included. 38 participants completed all 4 sessions. A moderate correlation between the average total score and robotic experience was identified for the first attempt (Spearman r = 0.58; p = 0.0004). A difference in average total score was observed between novices and intermediates [median score 61% (IQR 52-66) vs. 83% (IQR 75-91), adjusted p < 0.0001], as well as novices and experienced [median score 61% (IQR 52-66) vs. 80 (IQR 69-85), adjusted p = 0.002]. All three groups improved their performance between the 1st and 10th attempts (p < 0.00). This study describes validity evidence for a virtual-reality simulator for basic robotic surgical skills, which can be used for assessment of basic competency and as a training tool. However, more validity evidence is needed before it can be used for certification or high-stakes assessment.

The aim of this study was to make the first evaluation of the psychometric properties of the Affect Phobia Test, using the Swedish translation - a test developed to screen the ability to experience, express and regulate emotions. Data was collected from a clinical sample (N = 82) of patients with depression and/or anxiety participating in randomized controlled trial of Internet-based affect-focused treatment, and a university student sample (N = 197). The internal consistency for the total score was satisfactory (Clinical sample α = 0.88/Student sample α = 0.84) as well as for all the affective domains, except Anger/Assertion (α = 0.44/0.36), Sadness/Grief (α = 0.24/0.46) and Attachment/Closeness (α = 0.67/0.69). Test retest reliability was satisfactory (ICC > 0.77) for the total score and for all the affective domains except for Sadness/Grief (ICC = 0.04). The exploratory factor analysis resulted in a six-factor solution and did only moderately match the test's original affective domains. An empirical cut-off between the clinical and the university student sample were calculated and yielded a cut-off of 72 points. As expected, the Affect Phobia test showed negative significant correlations in the clinical group with measures on depression (rxy  = -0.229; p < 0.01) and anxiety (rxy  = -0.315; p < 0.05). The conclusion is that the psychometric properties are satisfactory for the total score of the Affect Phobia Test but not for some of the test's affective domains. Consequently the domains should not be used as subscales. The test can discriminate between individuals who seek help for psychological problems and those who do not. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

The value of the UK Clinical Aptitude Test in predicting pre-clinical performance: a prospective cohort study at Nottingham Medical School.

PubMed

Yates, Janet; James, David

2010-07-28

The UK Clinical Aptitude Test (UKCAT) was introduced in 2006 as an additional tool for the selection of medical students. It tests mental ability in four distinct domains (Quantitative Reasoning, Verbal Reasoning, Abstract Reasoning, and Decision Analysis), and the results are available to students and admissions panels in advance of the selection process. As yet the predictive validity of the test against course performance is largely unknown.The study objective was to determine whether UKCAT scores predict performance during the first two years of the 5-year undergraduate medical course at Nottingham. We studied a single cohort of students, who entered Nottingham Medical School in October 2007 and had taken the UKCAT. We used linear regression analysis to identify independent predictors of marks for different parts of the 2-year preclinical course. Data were available for 204/260 (78%) of the entry cohort. The UKCAT total score had little predictive value. Quantitative Reasoning was a significant independent predictor of course marks in Theme A ('The Cell'), (p = 0.005), and Verbal Reasoning predicted Theme C ('The Community') (p < 0.001), but otherwise the effects were slight or non-existent. This limited study from a single entry cohort at one medical school suggests that the predictive value of the UKCAT, particularly the total score, is low. Section scores may predict success in specific types of course assessment.The ultimate test of validity will not be available for some years, when current cohorts of students graduate. However, if this test of mental ability does not predict preclinical performance, it is arguably less likely to predict the outcome in the clinical years. Further research from medical schools with different types of curriculum and assessment is needed, with longitudinal studies throughout the course.

Trunk control test as an early predictor of stroke rehabilitation outcome.

1997-07-01

The aim of this study was to investigate the construct and predictive validity of the Trunk Control Test (TCT) in postacute stroke patients by comparing TCT scores at admission and discharge with the Functional Independence Measure (FIM) scores. Forty-nine patients participated in the study. The TCT examines four movements: rolling from a supine position to the weak side (T1) and to the strong side (T2), sitting up from a lying-down position (T3), and sitting balance (T4). The FIM is an 18-item scale (13 motor [motFIM] and 5 cognitive [cognFIM]) used to determine the level of dependence of patients in daily life. Thirty-six patients (73%) increased their TCT overall score at discharge. The TCT item-total correlations were high, both at admission and discharge (P < .0001). The individual TCT items were intercorrelated. Furthermore, the homogeneity of the TCT was confirmed by a high Cronbach's index. High correlations were found between admission and discharge scores in the different tests (TCT, FIM, and motFIM; P < .0001) and between TCT at admission and FIM (P < .0001) and motFIM (P < .0001) at admission. TCT at admission alone explained 71% of the variance in motFIM at discharge. The TCT showed a good sensitivity to change in assessing recovery of stroke patients. The high item-total correlation and Cronbach's alpha value of the TCT suggest that there is one homogeneous construct underlying the item list. The TCT construct validity was confirmed by the correlation between this test and the FIM scores. TCT at admission predicted motFIM at discharge even better than motFIM at admission alone. Possibly, the TCT captures basic motor skills that foreshadow the recovery of more complex behavioral skills described by the FIM.

Ultrasound simulation allows students to virtually explore internal anatomy by producing accurate, moving, color, three-dimensional rendered slices from any angle or approach leaving the organs and their relationships intact without requirement for consumables. The aim was to determine the feasibility and efficacy of self-directed learning of cardiac anatomy with an ultrasound simulator compared to cadavers and plastic models. After a single cardiac anatomy lecture, fifty university anatomy students participated in a three-hour supervised self-directed learning exposure in groups of five, randomized to an ultrasound simulator or human cadaveric specimens and plastic models. Pre- and post-tests were conducted using pictorial and non-pictorial multiple-choice questions (MCQs). Simulator students completed a survey on their experience. Four simulator and seven cadaver group students did not attend after randomization. Simulator use in groups of five students was feasible and feedback from participants was very positive. Baseline test scores were similar (P = 0.9) between groups. After the learning intervention, there was no difference between groups in change in total test score (P = 0.37), whether they were pictorial (P = 0.6) or non-pictorial (P = 0.21). In both groups there was an increase in total test scores (simulator +19.8 ±12.4%% and cadaver: +16.4% ± 10.2, P < 0.0001), pictorial question scores (+22.9 ±18.0%, 19.7 ±19.3%, P < 0.001) and non-pictorial question scores (+16.7 ±18.2%, +13 ±15.4%, P = 0.002). The ultrasound simulator appears equivalent to human cadaveric prosections for learning cardiac anatomy. © 2014 American Association of Anatomists.

Testing manifest monotonicity using order-constrained statistical inference.

2013-01-01

Most dichotomous item response models share the assumption of latent monotonicity, which states that the probability of a positive response to an item is a nondecreasing function of a latent variable intended to be measured. Latent monotonicity cannot be evaluated directly, but it implies manifest monotonicity across a variety of observed scores, such as the restscore, a single item score, and in some cases the total score. In this study, we show that manifest monotonicity can be tested by means of the order-constrained statistical inference framework. We propose a procedure that uses this framework to determine whether manifest monotonicity should be rejected for specific items. This approach provides a likelihood ratio test for which the p-value can be approximated through simulation. A simulation study is presented that evaluates the Type I error rate and power of the test, and the procedure is applied to empirical data.

The aim of this study was to validate the Dutch translation of the low anterior resection syndrome (LARS) score in a population of Dutch rectal cancer patients. Patients who underwent surgery for rectal cancer received the LARS score questionnaire, a single quality of life (QoL) category question and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire. A subgroup of patients received the LARS score twice to assess the test-retest reliability. A total of 165 patients were included in the analysis, identified in six Dutch centres. The response rate was 62.0%. The percentage of patients who reported 'major LARS' was 59.4%. There was a high proportion of patients with a perfect or moderate fit between the QoL category question and the LARS score, showing a good convergent validity. The LARS score was able to discriminate between patients with or without neoadjuvant radiotherapy (P = 0.003), between total and partial mesorectal excision (P = 0.008) and between age groups (P = 0.039). There was a statistically significant association between a higher LARS score and an impaired function on the global QoL subscale and the physical, role, emotional and social functioning subscales of the EORTC QLQ-C30 questionnaire. The test-retest reliability of the LARS score was good, with an interclass correlation coefficient of 0.79. The good psychometric properties of the Dutch version of the LARS score are comparable overall to the earlier validations in other countries. Therefore, the Dutch translation can be considered to be a valid tool for assessing LARS in Dutch rectal cancer patients.

Objectives To define the emotional intelligence (EI) profile of emergency medicine (EM) residents, and identify resident EI strengths and weaknesses. Methods First-, second-, and third-year residents (post-graduate years [PGY] 1, 2, and 3, respectively) of Thomas Jefferson University Hospital’s EM Program completed the Emotional Quotient Inventory (EQ-i 2.0), a validated instrument offered by Multi-Health Systems. Reported scores included total mean EI, 5 composite scores, and 15 subscales of EI. Scores are reported as means with 95% CIs. The unpaired, two-sample t-test was used to evaluate differences in means. Results Thirty-five residents completed the assessment (response rate 97.2%). Scores were normed to the general population (mean 100, SD 15). Total mean EI for the cohort was 103 (95%CI,100-108). EI was higher in female (107) than male (101) residents. PGY-2s demonstrated the lowest mean EI (95) versus PGY-1s (104) and PGY-3s (110). The difference in PGY-3 EI (110; 95%CI,103-116) and PGY-1 EI (95, 95%CI,87-104) was statistically significant (unpaired t-test, p<0.01). Highest composite scores were in interpersonal skills (107; 95%CI,100-108) and stress management (105; 95%CI,101-109). Subscale cohort strengths included self-actualization (107); empathy (107); interpersonal relationships (106); impulse control (106); and stress tolerance (106). Lowest subscale score was in assertiveness (98). Self-regard (89), assertiveness (88), and independence (90) were areas in which PGY-2s attained relatively lower scores (unpaired t-test, p<0.05) compared to their peers and the general population. PGY-3’s scored highest in nearly all subscales. Conclusions The EQ-i offers insight into training that may assist in developing EM residents, specifically in self-regard, assertiveness, and self-expression. Further study is required to ascertain if patterns in level of training are idiosyncratic or relate to the natural maturation of residents.   PMID:29286282

As the need for joint replacements will continue to rise, the outcome of primary total hip replacement (THR) must be improved and stabilised at a high level. In this study, we investigated whether pre-operative risk factors, such as gender, age and body weight at the time of the surgery or a restricted physical status (ASA-Status > 2 or Kellgren and Lawrence grade > 2) have a negative influence on the post-operative results or on patient satisfaction. Retrospective data collection and a prospective interview were performed with 486 patients who underwent primary total hip replacement between January 2007 and December 2010 in our hospital. The patients' satisfaction and quality of life were surveyed with the WOMAC-Score, SF-36 and EuroQol-5. Differences between more than two independent spot tests were tested with the non-parametric Kruskal-Wallis test. Differences between two independent spot tests were tested with the non-parametric Mann-Whitney U test. The frequencies were reported and odds ratios calculated. The confidence interval was set at 95 %. The level of significance was p < 0.05. The average WOMAC-Score was 77.1 and the total score of the SF-36 was 66.9 points. The patients declared an average EuroQol Index of 0.81. Our data show that the patients' gender did not influence the duration of surgery or the scores. However, female patients tended to exhibit more postoperative complications. However, increased patient age at the time of surgery was associated with an increased OR for duration of surgery, length of stay and risk of complications. Patients who had a normal body weight at time of the surgery showed better peri- and post-operative results. We showed that the preoperative estimated Kellgren and Lawrence grade had a significant influence on the duration of surgery. The ASA classification influenced the duration of surgery as well the length of stay and the rate of complications. The quality of results after primary THR depends on preoperative factors. Existing comorbidities have a significant influence on the duration of surgery and therefore on the perioperative rate of complications and the postoperative outcome. Despite improvements in the functional and subjective outcome after primary THR, an adverse preoperative symptomatic status is associated with less favourable postoperative results.

To investigate the effects of isokinetic exercise on pain and functional test scores of recreational athletes with chondromalacia patellae (CMP) and to examine the correlation between isokinetic parameters and functional tests or pain score. The functional ability of 30 recreational athletes with unilateral CMP was evaluated using six different tests. Pain scores were assessed during daily activities before and after the treatment protocol. Isokinetic exercise sessions were carried out at angular velocities of 60 degrees /s (25-90 degrees range of flexion) and 180 degrees /s (full range). These sessions were repeated three times a week for six weeks. Quadriceps and hamstring peak torque, total work, and endurance ratios had improved significantly after the treatment, as did the functional parameters and pain scores. There was a poor correlation between the extensor endurance ratio and one leg standing test. A moderate correlation between the visual analogue scale and the extensor endurance ratio or flexion endurance ratio was also found. The isokinetic exercise programme used in this study had a positive effect on muscle strength, pain score, and functional ability of knees with CMP. The improvement in the functional capacity did not correlate with the isokinetic parameters.

Total joint arthroplasty (TJA) is an effective and successful treatment of osteoarthritis of the hip and knee as quantified by several measures, such as pain relief, improved walking, improved self-care, functions, and increased quality of life. Data are lacking as to the definition of a satisfactory functional gain in a postacute setting and identifying the characteristics of older patients with TJA who may achieve that gain. Our aim was to characterize patients who may achieve a satisfactory functional gain in a postacute rehabilitation setting following TJA. This was a retrospective study of 180 patients with TJA admitted during 2010-2013. The main outcome measures were the Functional Independence Measure (FIM), the Montebello Rehabilitation Factor Score (MRFS) on the motor FIM, and the Timed Get Up and Go Test. Satisfactory functional gain was defined as an mFIM MRFS score above median score. Comparisons of clinical and demographic characteristics between patients who achieved a satisfactory functional gain versus those who did not were performed by the Mann-Whitney U test and the χ test. The proportion of patients who achieved a satisfactory functional gain was similar in the total knee arthroplasty and total hip arthroplasty (THA) groups. The most significant characteristic of patients who achieved a satisfactory functional gain was their admission functional ability. Age negatively impacted the ability to achieve a satisfactory functional gain in patients with THA. Functional level on admission is the best predictive factor for a better rehabilitation outcome for patients with TJA. Age negatively affects functional gain in patients with THA.

This study compared the effects of reading-oriented tasks and writing-oriented tasks on students' reading comprehension of geometry proof (RCGP). The reading-oriented tasks were designed with reading strategies and the idea of problem posing. The writing-oriented tasks were consistent with usual proof instruction for writing a proof and applying it. Twenty-two classes of ninth-grade students ( N = 683), aged 14 to 15 years, and 12 mathematics teachers participated in this quasi-experimental classroom study. While the experimental group was instructed to read and discuss the reading tasks in two 45-minute lessons, the control group was instructed to prove and apply the same propositions. Generalised estimating equation (GEE) method was used to compare the scores of the post-test and the delayed post-test with the pre-test scores as covariates. Results showed that the total scores of the delayed post-test of the experimental group were significantly higher than those of the control group. Furthermore, the scores of the experimental group on all facets of reading comprehension except the application facet were significantly higher than those of the control group for both the post-test and delayed post-test.

2008-01-01

The authors examined the factor structure of the Minnesota Nicotine Withdrawal Scale (MNWS) using confirmatory factor analysis in clinical research samples of smokers trying to quit (n = 723). Three confirmatory factor analytic models, based on previous research, were tested with each of the 3 study samples at multiple points in time. A unidimensional model including all 8 MNWS items was found to be the best explanation of the data. This model produced fair to good internal consistency estimates. Additionally, these data revealed that craving should be included in the total score of the MNWS. Factor scores derived from this single-factor, 8-item model showed that increases in withdrawal were associated with poor smoking outcome for 2 of the clinical studies. Confirmatory factor analyses of change scores showed that the MNWS symptoms cohere as a syndrome over time. Future investigators should report a total score using all of the items from the MNWS.

An increasing number of studies have presented evidence that various patient groups with acquired brain injury suffer from navigation problems in daily life. This skill is, however, scarcely addressed in current clinical neuropsychological practice and suitable diagnostic instruments are lacking. Real-world navigation tests are limited by geographical location and associated with practical constraints. It was, therefore, investigated whether virtual navigation might serve as a useful alternative. To investigate the convergent validity of virtual navigation testing, performance on the Virtual Tubingen test was compared to that on an analogous real-world navigation test in 68 chronic stroke patients. The same eight subtasks, addressing route and survey knowledge aspects, were assessed in both tests. In addition, navigation performance of stroke patients was compared to that of 44 healthy controls. A correlation analysis showed moderate overlap (r = .535) between composite scores of overall real-world and virtual navigation performance in stroke patients. Route knowledge composite scores correlated somewhat stronger (r = .523) than survey knowledge composite scores (r = .442). When comparing group performances, patients obtained lower scores than controls on seven subtasks. Whereas the real-world test was found to be easier than its virtual counterpart, no significant interaction-effects were found between group and environment. Given moderate overlap of the total scores between the two navigation tests, we conclude that virtual testing of navigation ability is a valid alternative to navigation tests that rely on real-world route exposure.

The aim of this study was to evaluate the effect of knee position during wound closure (flexed vs. extended) in total knee arthroplasty on knee strength and function, as determined by knee society scores and isokinetic testing of extensor and flexor muscle groups. In a prospective, randomized, double-blind trial, 29 patients were divided in two groups: for Group 1 patients, surgical closing was performed with the knee extended, and for Group 2 patients, the knee flexed at 90°. All the patients were treated with the same anaesthesia method, surgical team, surgical technique, prosthesis type, and rehabilitation process. American Knee Society Score values and knee flexion degrees were recorded. Isokinetic muscle strength measurements of both knees in flexion and extension were taken using 60° and 180°/s angular velocity. The peak torque and total work values, isokinetic muscle strength differences, and total work difference values were calculated for surgically repaired and healthy knees. No significant difference in the mean American Knee Society Score values and knee flexion degrees was observed between the two groups. However, using isokinetic evaluation, a significant difference was found in the isokinetic muscle strength differences and total work difference of the flexor muscle between the two groups when patients were tested at 180°/s. Less loss of strength was detected in the isokinetic muscle strength differences of the flexor muscle in Group 2 (-4.2%) than in Group 1 (-23.1%). For patients undergoing total knee arthroplasty, post-operative flexor muscle strength is improved if the knee is flexed during wound closure. II.

This study evaluates the influence of visual-spatial perception on laparoscopic performance of novices with a virtual reality simulator (LapSim(R)). Twenty-four novices completed standardized tests of visual-spatial perception (Lameris Toegepaste Natuurwetenschappelijk Onderzoek [TNO] Test(R) and Stumpf-Fay Cube Perspectives Test(R)) and laparoscopic skills were assessed objectively, while performing 1-h practice sessions on the LapSim(R), comprising of coordination, cutting, and clip application tasks. Outcome variables included time to complete the tasks, economy of motion as well as total error scores, respectively. The degree of visual-spatial perception correlated significantly with laparoscopic performance on the LapSim(R) scores. Participants with a high degree of spatial perception (Group A) performed the tasks faster than those (Group B) who had a low degree of spatial perception (p = 0.001). Individuals with a high degree of spatial perception also scored better for economy of motion (p = 0.021), tissue damage (p = 0.009), and total error (p = 0.007). Among novices, visual-spatial perception is associated with manual skills performed on a virtual reality simulator. This result may be important for educators to develop adequate training programs that can be individually adapted.

To correlate osteochondral repair assessed by validated macroscopic scoring systems with established semiquantitative histological analyses in an ovine model and to test the hypothesis that important macroscopic individual categories correlate with their corresponding histological counterparts. In the weight-bearing portion of medial femoral condyles (n = 38) of 19 female adult Merino sheep (age 2-4 years; weight 70 ± 20 kg) full-thickness chondral defects were created (size 4 × 8 mm; International Cartilage Repair Society (ICRS) grade 3C) and treated with Pridie drilling. After sacrifice, 1520 blinded macroscopic observations from three observers at 2-3 time points including five different macroscopic scoring systems demonstrating all grades of cartilage repair where correlated with corresponding categories from 418 blinded histological sections. Categories "defect fill" and "total points" of different macroscopic scoring systems correlated well with their histological counterparts from the Wakitani and Sellers scores (all P ≤ 0.001). "Integration" was assessed in both histological scoring systems and in the macroscopic ICRS, Oswestry and Jung scores. Here, a significant relationship always existed (0.020 ≤ P ≤ 0.049), except for Wakitani and Oswestry (P = 0.054). No relationship was observed for the "surface" between histology and macroscopy (all P > 0.05). Major individual morphological categories "defect fill" and "integration", and "total points" of macroscopic scoring systems correlate with their corresponding categories in elementary and complex histological scoring systems. Thus, macroscopy allows to precisely predict key histological aspects of articular cartilage repair, underlining the specific value of macroscopic scoring for examining cartilage repair.

Objectives: This trial was conducted to test the effects of an alpha7 nicotinic receptor full agonist, TC-5619, on negative and cognitive symptoms in subjects with schizophrenia. Methods: In 64 sites in the United States, Russia, Ukraine, Hungary, Romania, and Serbia, 477 outpatients (18–65 years; male 62%; 55% tobacco users) with schizophrenia, treated with a new-generation antipsychotic, were randomized to 24 weeks of placebo (n = 235), TC-5619, 5mg (n = 121), or TC-5619, 50mg (n = 121), administered orally once daily. The primary efficacy measure was the Scale for the Assessment of Negative Symptoms (SANS) composite score. Key secondary measures were the Cogstate Schizophrenia Battery (CSB) composite score and the University of California San Diego Performance-Based Skills Assessment-Brief Version (UPSA-B) total score. Secondary measures included: Positive and Negative Syndrome Scale in Schizophrenia (PANSS) total and subscale scores, SANS domain scores, CSB item scores, Clinical Global Impression-Global Improvement (CGI-I) score, CGI-Severity (CGI-S) score, and Subject Global Impression-Cognition (SGI-Cog) total score. Results: SANS score showed no statistical benefit for TC-5619 vs placebo at week 24 (5mg, 2-tailed P = .159; 50mg, P = .689). Likewise, no scores of CSB, UPSA-B, PANSS, CGI-I, CGI-S, or SGI-Cog favored TC-5619 (P > .05). Sporadic statistical benefit favoring TC-5619 in some of these outcome measures were observed in tobacco users, but these benefits did not show concordance by dose, country, gender, or other relevant measures. TC-5619 was generally well tolerated. Conclusion: These results do not support a benefit of TC-5619 for negative or cognitive symptoms in schizophrenia. PMID:26071208

Minimally important difference of the Treatment Satisfaction with Medicines Questionnaire (SATMED-Q)

PubMed Central

2011-01-01

Background A previous study has documented the reliability and validity of the Treatment Satisfaction with Medicines Questionnaire (SATMED-Q) in exploring patient satisfaction with medicines for chronic health conditions in routine medical practice, but the minimally important difference (MID) of this tool is as yet unknown. The objective of this research was to estimate the MID for the SATMED-Q total score and six constituent domains. Methods The sample of patients (456 subjects, mean age 59 years, 53% male) used for testing psychometric properties was also used to assess MID. Item #14 of the Treatment Satisfaction Questionnaire for Medication (TSQM) was used as an anchor reference since it directly explores satisfaction with medicine on a 7-point ordinal scale (from extremely satisfied to extremely dissatisfied, with a neutral category). Patients were classified into four categories according to responses to this item (extremely satisfied/dissatisfied, very satisfied/dissatisfied, satisfied/dissatisfied, neither satisfied nor dissatisfied (neutral), and calculations were made for the total score and each domain of the SATMED-Q using standardised scores. The mean absolute differences in total score (and domains) between the neutral category and the satisfied/dissatisfied category were considered to be the MID. Effect sizes (ES) were also computed. Results The MID for the total score was 13.4 (ES = 0.91), while the domain values ranged from 10.3 (medical care domain, ES = 0.43) to 20.6 (impact on daily living, ES = 0.85). Mean differences in satisfaction (as measured by the total SATMED-Q score and domain scores) using the levels of satisfaction established by item #14 were significantly different, with F values ranging from 12.2 to 88.8 (p < 0.001 in all cases). Conclusion The SATMED-Q was demonstrated to be responsive to different levels of patient satisfaction with therapy in chronically ill subjects. The MID obtained was 13.4 points for the overall normalised scoring scale, and between 10.3 and 20.6 points for domains. PMID:22014277

Intake of added sugars, mainly fructose and sucrose, has been associated with risk factors for cognitive impairment, such as obesity, the metabolic syndrome and type 2 diabetes. The objective of this analysis was to examine whether habitual intakes of total sugars, added sugars, sugar-sweetened beverages or sweetened solid foods are associated with cognitive function. The present study included 737 participants without diabetes, aged 45–75 years, from the Boston Puerto Rican Health Study, 2004–9. Cognitive function was measured with a battery of seven tests: Mini-Mental State Examination (MMSE), word list learning, digit span, clock drawing, figure copying, and Stroop and verbal fluency tests. Usual dietary intake was assessed with a validated FFQ. Greater intakes of total sugars, added sugars and sugar-sweetened beverages, but not of sugar-sweetened solid foods, were significantly associated with lower MMSE score, after adjusting for covariates. Adjusted OR for cognitive impairment (MMSE score <24) were 2·23 (95 % CI 1·24, 3·99) for total sugars and 2·28 (95 % CI 1·26, 4·14) for added sugars, comparing the highest with lowest intake quintiles. Greater intake of total sugars was also significantly associated with lower word list learning score. In conclusion, higher sugar intake appears to be associated with lower cognitive function, but longitudinal studies are needed to clarify the direction of causality. PMID:21736803

According with Chinese legal system, to develop a competency to stand trial rating scale in offenders with mental disorders. Proceeding from the juristical elements, 15 items were extracted and formulated a preliminary instrument named the competency to stand trial rating scale in offenders with mental disorders. The item analysis included six aspects, which were critical ratio, item-total correlation, corrected item-total correlation, alpha value if item deleted, communalities of items, and factor loading. The Logistic regression equation and cut-off score of ROC curve were used to explore the diagnostic efficiency. The data of critical ratio of extreme group were 18.390-46.763; item-total correlation, 0.639-0.952; corrected item-total correlation, 0.582-0.944; communalities of items, 0.377-0.916; and factor loadings, 0.614-0.957. Seven items were included in the regression equation and the accuracy of back substitution test was 96.0%. The score of 33 was ascertained as the cut-off score by ROC fitting curve, the overlapping ratio compared with the expertise was 95.8%. The sensibility and the specificity were 0.938 and 0.966, respectively, while the positive and negative likelihood ratios were 27.67 and 0.06, respectively. With all items satisfied the requirement of homogeneity test, the rating scale has a reasonable construct and excellent diagnostic efficiency.

A test of prospect theory.

PubMed

Feeny, David; Eng, Ken

2005-01-01

Prospect theory (PT) hypothesizes that people judge states relative to a reference point, usually assumed to be their current health. States better than the reference point are valued on a concave portion of the utility function; worse states are valued on a convex portion. Using prospectively collected utility scores, the objective is to test empirically implications of PT. Osteoarthritis (OA) patients undergoing total hip arthroplasty periodically provided standard gamble scores for three OA hypothetical states describing mild, moderate, and severe OA as well as their subjectively defined current state (SDCS). Our hypothesis was that most patients improved between the pre- and postsurgery assessments. According to PT, scores for hypothetical states previously > SDCS but now < SDCS should be lower at the postsurgery assessment. Fourteen patients met the criteria for testing the hypothesis. Predictions were confirmed for 0 patients; there was no change or mixed results for 6 patients (42.9 percent); and scores moved in the direction opposite to that predicted by PT for 8 patients (57.1 percent). In general, the direction and magnitude of the changes in hypothetical-state scores do not conform to the predictions of PT.

Famous face recognition and naming test: a normative study.

Tests of famous face recognition and naming, and tasks assessing semantic knowledge about famous people after presentation either of their faces or their names are often used in the neuropsychological examination of aphasic, amnesic and demented patients. A total of 187 normal subjects took part in this study. The aim was to collect normative data for a newly devised test including five subtests: famous face naming, fame judgement after face presentation and after name presentation, semantic knowledge about famous people after face presentation and after name presentation. Norms were calculated taking into account demographic variables such as age, sex and education and adjusted scores were used to determine inferential cut-off scores and to compute equivalent scores. Multiple regression analyses showed that age and education influenced significantly the performance on most subtests, but sex had no effect on any of them. Scores of the subtest evaluating fame judgements after name presentation were significantly influenced only by education. The only subtest whose scores were not influenced by any demographic variable was fame judgement after face presentation.

Efficient clinical evaluation of guideline quality: development and testing of a new tool

PubMed Central

2014-01-01

Background Evaluating the methodological quality of clinical practice guidelines is essential before deciding which ones which could best inform policy or practice. One current method of evaluating clinical guideline quality is the research-focused AGREE II instrument. This uses 23 questions scored 1–7, arranged in six domains, which requires at least two independent testers, and uses a formulaic weighted domain scoring system. Following feedback from time-poor clinicians, policy-makers and managers that this instrument did not suit clinical need, we developed and tested a simpler, shorter, binary scored instrument (the iCAHE Guideline Quality Checklist) designed for single users. Methods Content and construct validity, inter-tester reliability and clinical utility were tested by comparing the new iCAHE Guideline Quality Checklist with the AGREE II instrument. Firstly the questions and domains in both instruments were compared. Six randomly-selected guidelines on a similar theme were then assessed by three independent testers with different experience in guideline quality assessment, using both instruments. Per guideline, weighted domain and total AGREE II scores were calculated, using the scoring rubric for three testers. Total iCAHE scores were calculated per guideline, per tester. The linear relationship between iCAHE and AGREE II scores was assessed using Pearson r correlation coefficients. Score differences between testers were assessed for the iCAHE Guideline Quality Checklist. Results There were congruent questions in each instrument in four domains (Scope & Purpose, Stakeholder involvement, Underlying evidence/Rigour, Clarity). The iCAHE and AGREE II scores were moderate to strongly correlated for the six guidelines. There was generally good agreement between testers for iCAHE scores, irrespective of their experience. The iCAHE instrument was preferred by all testers, and took significantly less time to administer than the AGREE II instrument. However, the use of only three testers and six guidelines compromised study power, rendering this research as pilot investigations of the psychometric properties of the iCAHE instrument. Conclusion The iCAHE Guideline Quality Checklist has promising psychometric properties and clinical utility. PMID:24885893

To our knowledge, few studies have combined an objective measure of vision-related performance (VRP) and subjective measures of vision-related quality of life (VRQoL) with clinically related visual parameters, particularly in a large, prospective, cohort study setting. To examine the relationships between clinical visual assessments and both a VRP and 2 self-reported VRQoL measurements. Patients (N = 161) with moderate-stage glaucoma recruited from the Glaucoma Service at Wills Eye Hospital, Philadelphia, Pennsylvania, were enrolled from May 2012 to May 2014 in an ongoing prospective, 4-year longitudinal observational study. This report includes cross-sectional results from the baseline visit. Patients received a complete ocular examination, automated visual field (VF) test and Cirrus optical coherence tomographic scan. Contrast sensitivity was measured with the Pelli-Robson and the Spaeth-Richman Contrast Sensitivity (SPARCS) tests. Vision-related performance was assessed by the Compressed Assessment of Ability Related to Vision (CAARV) test. Vision-related QoL was assessed by the National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ-25) and a modified Glaucoma Symptom Scale (MGSS). Correlations between clinical measures and CAARV, NEI-VFQ-25, and MGSS scores. A total of 161 patients were enrolled in the study. The strongest correlation was found between SPARCS score in the better eye and total CAARV score (r = 0.398; 95% CI, 0.235-0.537; P < .001). The CAARV score also correlated with the Pelli-Robson score (r = 0.353; 95% CI, 0.186-0.499; P = .001), VF mean deviation (r = 0.366; 95% CI, 0.200-0.510; P < .001), and VA (r = -0.326, 95% CI = -0.476 to -0.157; P = .003) in the better eye. There were more statistically significant correlations between contrast sensitivity tests and VF mean deviation with VRQoL measurements than with other clinical measures (visual acuity, intraocular pressure, Disc Damage Likelihood Scale, and mean retinal nerve fiber layer thickness). The MGSS scores were lower (worse) in women compared with men (P = .03 for binocular, P = .01 for better eye, and P = .05 for the worse eye). Structural measures (eg, Disc Damage Likelihood Scale, and retinal nerve fiber layer thickness) were generally not informative with respect to VRP or VRQoL. Contrast sensitivity tests and VF mean deviation were associated with both objective measures of the ability to act and subjective measurements of VRQoL. The strongest correlation was between SPARCS score (contrast sensitivity) in the better eye and total CAARV score. Therefore, measurement of contrast sensitivity should be considered when evaluating patients' VRQoL. The results of this study were limited by the patient population and apply only within the bounds of the tested cohort.

The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and the Western Ontario Rotator Cuff (WORC) index are 2 widely used patient-reported questionnaires in individuals with rotator cuff (RC) tendinopathy. In contrast to the WORC index, for which the items are specific to the affected shoulder, the items of the DASH questionnaire assess the ability to perform activities regardless of the arm used. The objective of this study is to determine whether scores on the DASH questionnaire and WORC index are affected if the symptoms are on the dominant or nondominant side in individuals with RC tendinopathy. Given the number of items that can be influenced by dominance, the hypothesis is that DASH scores will be impacted by the side of the symptoms. Individuals with RC tendinopathy (N = 149) completed questions on symptomatology and hand dominance, the DASH questionnaire, and the WORC index. Differences in total scores (independent t test) and single items (Wilcoxon rank sum test) were compared between groups of participants with dominant-side symptoms and those without dominant-side symptoms. No significant differences were observed for WORC or DASH total scores when comparing participants with and without symptoms on their dominant side. Single-item comparison revealed more items being affected by symptom side on the DASH questionnaire (6 of 30 items) than on the WORC index (2 of 21 items). The side of the symptoms does not influence the DASH and WORC total scores, as there are no systematic differences between individuals with and without symptoms in their dominant shoulder. However, the presence of dominant symptoms does influence item scores more on the DASH questionnaire than on the WORC index. Copyright © 2018 Journal of Shoulder and Elbow Surgery Board of Trustees.

Despite the wide use of the neck disability index (NDI) for assessing disability in patients with neck pain, the NDI has not yet been translated and validated in Urdu. The first purpose of the present study was to translate and cross-culturally adapt the NDI into the Urdu language (NDI-U). The second purpose was to investigate the reliability, validity and responsiveness of the NDI-U in Urdu-speaking patients experiencing chronic mechanical neck pain (CMNP). Translation and cross-cultural adaptation of the original version of the NDI were carried out using previously described procedures. Seventy-six patients with CMNP and thirty healthy participants were recruited for the study. NDI-U and visual analogue scales for pain intensity (VAS pain ) and disability (VAS disability ) were administered to all the participants at baseline and to the patients 3 weeks after receiving physiotherapy intervention. The global rating of change scale (GROC) was also administered at this time. Test-retest reliability and internal consistency were carried out on forty-six randomly selected patients two days after they completed the NDI-U. The NDI-U was evaluated for factor analysis, content validity, construct validity (discriminative and convergent validity) and responsiveness. An intra-class correlation coefficient (ICC 2,1 ) revealed excellent test-retest reliability for all items (ICC 2,1  = 0.86-0.98) and total scores (ICC 2,1  = 0.99) of the NDI-U. The NDI-U was found internally consistent with a Cronbach's alpha of 0.90 and a fair to good correlation between single items and the NDI-U total scores (r = 0.34 to 0.89). Factor analysis of the NDI-U produced two factors explaining 66.71% of the variance. Content validity was good, as no floor or ceiling effects were detected for the NDI-U total score. To determine discriminative validity, an independent t-test revealed a significant difference in the NDI-U total scores between the patients and healthy controls (P < 0.001). For convergent validity, Pearson's correlation coefficient showed a strong correlation between NDI-U and VAS disability (r = 0.83, P < 0.001) and a moderate correlation between NDI-U and VAS pain (r = 0.62, P < 0.001). To measure responsiveness, an independent t-test showed a significant difference in the NDI-U change scores between the stable and the improved groups (P < 0.001). Furthermore, moderate correlations were found between the NDI-U change scores and the GROC (r = 0.50, P < 0.001), VAS disability change scores (r = 0.58, P < 0.001) and VAS pain change scores (r = 0.55, P < 0.001). The results showed that the NDI-U is a reliable, valid and responsive questionnaire to measure disability in Urdu-speaking patients with CMNP.

Increasing literature has shown the usefulness of a dimensional approach to autism. The present study aimed to determine the psychometric properties of the Adult Autism Subthreshold Spectrum (AdAS Spectrum), a new questionnaire specifically tailored to assess subthreshold forms of autism spectrum disorder (ASD) in adulthood. 102 adults endorsing at least one DSM-5 symptom criterion for ASD (ASDc), 143 adults diagnosed with a feeding and eating disorder (FED), and 160 subjects with no mental disorders (CTL), were recruited from 7 Italian University Departments of Psychiatry and administered the following: SCID-5, Autism-Spectrum Quotient (AQ), Ritvo Autism and Asperger Diagnostic Scale 14-item version (RAADS-14), and AdAS Spectrum. The AdAS Spectrum demonstrated excellent internal consistency for the total score (Kuder-Richardson's coefficient=.964) as well as for five out of seven domains (all coefficients>.80) and sound test-retest reliability (ICC=.976). The total and domain AdAS Spectrum scores showed a moderate to strong (>.50) positive correlation with one another and with the AQ and RAADS-14 total scores. ASDc subjects reported significantly higher AdAS Spectrum total scores than both FED (p<.001) and CTL (p<.001), and significantly higher scores on the Childhood/adolescence, Verbal communication, Empathy, Inflexibility and adherence to routine, and Restricted interests and rumination domains (all p<.001) than FED, while on all domains compared to CTL. CTL displayed significantly lower total and domain scores than FED (all p<.001). A significant effect of gender emerged for the Hyper- and hyporeactivity to sensory input domain, with women showing higher scores than men (p=.003). A Diagnosis* Gender interaction was also found for the Verbal communication (p=.019) and Empathy (p=.023) domains. When splitting the ASDc in subjects with one symptom criterion (ASD 1 ) and those with a ASD, and the FED in subjects with no ASD symptom criteria (FED 0 ) and those with one ASD symptom criterion (FED 1 ) , a gradient of severity in AdAS Spectrum scores from CTL subjects to ASD patients, across FED 0 , ASD 1 , FED 1 was shown. The AdAS Spectrum showed excellent internal consistency and test-retest reliability and strong convergent validity with alternative dimensional measures of ASD. The questionnaire performed differently among the three diagnostic groups and enlightened some significant effects of gender in the expression of autistic traits. Copyright © 2016 Elsevier Inc.

The study presents data on the longitudinal administration of the Italian Edinburgh Cognitive and Behavioral ALS Screen (ECAS). We investigated cognitive-behavioral performance in a group of ALS patients over time and the feasibility of repeating the ECAS longitudinally compared with standard neuropsychological tests. Finally, correlations between clinical/genetic and cognitive/behavioral data were considered. One hundred and sixty-eight ALS patients were tested at baseline (T 0 ). Among these, 48 patients performed the ECAS after 6 months (T 1 ), 18 patients performed it at T 2 (12 months), and five patients were assessed after 24 months (T 3 ). Participants were also administered two cognitive test (FAB; MoCA) and psychological questionnaires (BDI; STAI/Y). The FBI was carried out with caregivers. No cognitive deterioration was found across follow-ups. In contrast, although scores did not change between T 0 and T 1 , scores improved significantly for ECAS Total/ALS Non-specific and Memory domains when the ECAS was repeated on three occasions (T 0 , T 1 , T 2 ). Apathy/Inertia was the most common behavioral symptom, but no worsening of behavioral scores was detected over time. After 12-24 months, patients were still able to perform the ECAS in total, in contrast to FAB and MoCA, which were only partially administrable. The significant improvement of some ECAS scores over time supports the presence of possible practice effects, particularly in the memory domain, highlighting the need to accommodate for these in longitudinal assessments, through healthy controls groups or alternate versions. This work represents the first Italian ECAS follow-up study and confirms ECAS feasibility in patients with increasing physical disability.

This study was carried out in order to determine professional self-concept and professional values in the students, who were studying in the final year of the nursing department in schools providing undergraduate education in the Inner Anatolia Region. This cross-sectional study was conducted on a total of 619 senior students of nursing departments in the Inner Anatolia Region. Data were collected using a Student Information Form, Professional Self-Concept Scale for the Student Nurses, and The Nurses' Professional Values Scale. Descriptive statistics, the Shapiro-Wilk test, the t-test, analysis of variance, and the Bonferroni tests were used for data analysis. Ethical Considerations: A written consent was obtained from Ethics Board of Erciyes University Faculty of Medicine and from nursing schools participating in the study. Prior to data collection, students were informed about the purpose of the study and gave written and verbal consents. Participation in the study was on voluntary basis. In the study, students' total and sub-dimension scores from the Professional Self-Concept Scale for the Student Nurses and total scores from the Nurses' Professional Values Scale were moderately high. It was detected that women received higher scores than men from the sub-dimension of professional attributes; the students who had positive perception of the nursing image and voluntarily selected their department received high scores from professional satisfaction, professional competence, and professional attributes sub-dimensions of the Professional Self-Concept Scale for the Student Nurses ( p < 0.001). In order to improve students' perceptions of professional self-concept and professional values, it is thought that students' awareness should be increased on these topics.

We tested a stepwise, community-based screening strategy for glucose intolerance in South Asians using a health questionnaire in conjunction with body mass index (BMI). Anthropometric measurements (waist and hip circumference, sagittal diameter and percentage body fat) were then conducted in a hospital setting followed by an oral glucose tolerance test (OGTT) to identify subjects at the highest risk and analyse the factors predicting that risk. A health questionnaire was administered to 435 subjects in a community setting and BMI was measured. Subjects were graded by a risk score based on the health questionnaire as high, medium and low. Subjects with high and medium risk scores and a representative sample of those with low scores had anthropometric measurements in hospital followed by an OGTT. In total, 205 (47%) of the subjects had an OGTT performed. In total, 48.7% of the subjects tested with an OGTT had evidence of glucose dysregulation: 20% had diabetes and 28.7% had impaired glucose tolerance (IGT). Logistic regression model explained 49.1% of the total variability. The significant predictors of diabetes and IGT were Blood Glucose Monitoring Strips (BMI), random blood glucose (BM), sibling with diabetes and presence of diagnosed hypertension or ischaemic disease. Most of these predictors along with other heredity diabetes factors create a composite score, with high predictability, as the receiver operating curve analysis shows. We describe a simple, stepwise strategy in a community setting, based on a health questionnaire and anthropometric measurements, to explain about 50% of cases with IGT and diabetes and diagnose about 50% of cases from the population screened. We have also identified factors that predict the risk.

Spanish version of the Oral Health Impact Profile (OHIP-Sp).

Lopez, Rodrigo; Baelum, Vibeke

2006-07-07

The need for appraisal of oral health-related quality of life has been increasingly recognized over the last decades. The aims of this study were to develop a Spanish version (OHIP-Sp) of the Oral Health Impact Profile and to evaluate its convergent and discriminative validity, and its internal consistency. The original 49-items OHIP was translated to Spanish, revised for understanding and semantics by two independent dentists, and then translated back to English by an independent bilingual dentist. The data originated in a cross sectional study conducted among high school students from the Province of Santiago, Chile. The study group was sampled using a multistage random cluster procedure yielding 9,203 students aged 12-21 years. All selected students were invited to participate and all filled a questionnaire with information on socio-demographic factors; oral health related behaviors; and self-reported oral health status (good, fair or poor). From this group, 9,163 students also accepted to fill a detailed questionnaire on socio-economic indicators and to receive a clinical examination comprising direct recordings of clinical attachment levels (CAL) in molars and incisors, tooth loss, and the presence of necrotizing ulcerative gingival lesions. The participation rate and the questionnaire completeness were high with OHIP-Sp total scores being computed for 9,133 subjects. Self-perceived oral health status was associated with the total OHIP-Sp score and all its domains (Spearman rank correlation). The OHIP-Sp total score was also directly associated with the 4 dental outcomes investigated (Mann-Whitney test) and the largest impact was found for the outcomes, 'tooth loss' with a mean OHIP-Sp score = 13.5 and 'CAL > or = 3 mm' with a mean OHIP-Sp score = 13.0. The OHIP-Sp revealed suitable convergent and discriminative validity and appropriate internal consistency (Cronbach's alpha). Further studies on OHIP-Sp warrant the inclusion of populations with a higher disease burden; and the use of test-retest reliability exercises to evaluate the stability of the test.

The purpose of this study was to examine the association between cardiovascular risk estimated by the Framingham Risk Score and functional capacity in patients with peripheral artery disease using a 6-minute walk test. Fifty-six participants with intermittent claudication were recruited. The Framingham Risk Score was calculated and used to split the participants into two groups: Group A (mild and moderate risk) and group B (severe risk). The ankle-brachial index (ABI) was calculated for each leg using a handheld Doppler probe. Walking ability was verified by a 6-minute walk test. Descriptive statistics were used to describe the sample's demographic and clinical characteristics. To compare clinical data between the two groups, a t test or Mann-Whitney test was used as appropriate according to the type of variable being analyzed. The Pearson coefficient was used to verify the association between cardiovascular risk and functional capacity. Group A had 19 participants (60.5 ± 6.3 years; 36.8% male) and group B had 37 participants (63.4 ± 8.7 years; 73% male). No differences were observed when comparing the ABI between both groups. The total distances covered by the men in group A were shorter compared with those of group B (331.4 + 51.5 vs 257.9 + 84.0; P = .02). The cardiovascular risk score was negative and was significantly correlated with total distances for men (r = -0.53; P = .001) and with pain-free distances for women (r = -0.46; P = .03). Functional capacity, evaluated through a 6-minute walk test, seems to be associated with 10-year total mortality risk. Copyright © 2015 Society for Vascular Nursing, Inc. Published by Elsevier Inc.

This study aimed to test the applicability and effectiveness of the principles and informed consent form (ICF) template proposed by the Strategic Initiative for Developing Capacity in Ethical Review (SIDCER) across multiple clinical trials involving Thai research participants with various conditions. A single-center, randomized-controlled study nested with eight clinical trials was conducted at Thammasat University Hospital, Thailand. A total of 258 participants from any of the eight clinical trials were enrolled and randomly assigned to read either the SIDCER ICF (n = 130) or the conventional ICF (n = 128) of the respective trial. Their understanding of necessary information was assessed using the post-test questionnaire; they were allowed to consult a given ICF while completing the questionnaire. The primary endpoint was the proportion of the participants who had the post-test score of ≥80%, and the secondary endpoint was the total score of the post-test. The proportion of the participants in the SIDCER ICF group who achieved the primary endpoint was significantly higher than that of the conventional ICF group (60.8 vs. 41.4%, p = 0.002). The total score of the post-test was also significantly higher among the participants who read the SIDCER ICF than those who read the conventional ICF (83.3 vs. 76.0%, p < 0.001). The present study demonstrated that the SIDCER ICF was applicable and effective to improve Thai research participants' understanding of research information in diverse clinical trials. Using the SIDCER ICF methodology, clinical researchers can improve the quality of ICFs for their trials.

To evaluate a customized, portable Farnsworth-Munsell 100 (FM 100) hue viewing booth for compliance with colour vision testing standards and to compare it with room illumination in subjects with normal colour vision (trichromats), subjects with acquired colour vision defects (secondary to diabetes mellitus), and subjects with congenital colour vision defects (dichromats). Discrete wavelengths of the tube in the customized booth were measured using a spectrometer using the normal incident method and were compared with the spectral distribution of sunlight. Forty-eight subjects were recruited for the study and were divided into 3 groups: Group 1, Normal Trichromats (30 eyes); Group 2, Congenital Colour Vision Defects (16 eyes); and Group 3, Diabetes Mellitus (20 eyes). The FM 100 hue test performance was compared using two illumination conditions, booth illumination and room illumination. Total error scores of the classical method in Group 2 as mean+/-SD for room and booth illumination was 243.05+/-85.96 and 149.85+/-54.50 respectively (p=0.0001). Group 2 demonstrated lesser correlation (r=0.50, 0.55), lesser reliability (Cronbach's alpha, 0.625, 0.662) and greater variability (Bland & Altman value, 10.5) in total error scores for the classical method and the moment of inertia method between the two illumination conditions when compared to the other two groups. The customized booth demonstrated illumination meeting CIE standards. The total error scores were overestimated by the classical and moment of inertia methods in all groups for room illumination compared with booth illumination, however overestimation was more significant in the diabetes group.

There is a clinical need for objective evidence-based measures that are sensitive and specific to ADHD when compared with other neurodevelopmental disorders. This study evaluated the incremental validity of adding an objective measure of activity and computerised cognitive assessment to clinical rating scales to differentiate adult ADHD from Autism spectrum disorders (ASD). Adults with ADHD (n=33) or ASD (n=25) performed the QbTest, comprising a Continuous Performance Test with motion-tracker to record physical activity. QbTest parameters measuring inattention, impulsivity and hyperactivity were combined to provide a summary score ('QbTotal'). Binary stepwise logistic regression measured the probability of assignment to the ADHD or ASD group based on scores on the Conners Adult ADHD Rating Scale-subscale E (CAARS-E) and Autism Quotient (AQ10) in the first step and then QbTotal added in the second step. The model fit was significant at step 1 (CAARS-E, AQ10) with good group classification accuracy. These predictors were retained and QbTotal was added, resulting in a significant improvement in model fit and group classification accuracy. All predictors were significant. ROC curves indicated superior specificity of QbTotal. The findings present preliminary evidence that adding QbTest to clinical rating scales may improve the differentiation of ADHD and ASD in adults.

Background For students attending university courses, experiencing test anxiety (TA) dramatically impairs cognitive performance and success at exams. Whereas TA is a specific case of social phobia, emotional intelligence (EI) is an umbrella term covering interpersonal and intrapersonal skills, along with positive stress management, adaptability, and mood. In the present study, we tested the hypothesis that higher EI and lower TA are associated. Further, sex differences were explored. Method During an exam week, a total of 200 university students completed questionnaires covering sociodemographic information, TA, and EI. Results Higher scores on EI traits were associated with lower TA scores. Relative to male participants, female participants reported higher TA scores, but not EI scores. Intrapersonal and interpersonal skills and mood predicted low TA, while sex, stress management, and adaptability were excluded from the equation. Conclusion The pattern of results suggests that efforts to improve intrapersonal and interpersonal skills, and mood might benefit students with high TA. Specifically, social commitment might counteract TA. PMID:26834474

Identification of individuals in the prodromal phase of bipolar disorder and schizophrenia facilitates early intervention and promises an improved prognosis. There are no current assessment tools for clinical risk symptoms of bipolar disorder, and psychosis-risk assessment generally involves semi-structured interviews, which are time consuming and rater dependent. We present psychometric data on two novel quantitative questionnaires: the Washington Early Recognition Center Affectivity and Psychosis (WERCAP) Screen for assessing bipolar and psychotic disorder risk traits, and the accompanying WERC Stress Screen for assessing individual and total psychosocial stressor severities. Prevalence rates of the WERCAP Screen were evaluated among 171 community youth (aged 13-24 years); internal consistency was assessed and k-means cluster analysis was used to identify symptom groups. In 33 participants, test-retest reliability coefficients were assessed, and ROC curve analysis was used to determine the validity of the psychosis section of the WERCAP Screen (pWERCAP) against the Structured Interview of Psychosis-Risk Symptoms (SIPS). Correlations of the pWERCAP, the affectivity section of the WERCAP Screen (aWERCAP) and the WERC Stress Screen were examined to determine the relatedness of scores with cognition and clinical measures. Cluster analysis identified three groups of participants: a normative (47%), a psychosis-affectivity (18%) and an affectivity only (35%) group. Internal consistency of the aWERCAP and pWERCAP resulted in alphas of 0.87 and 0.92, and test-retest reliabilities resulted in intraclass correlation coefficients of 0.76 and 0.86 respectively. ROC curve analysis showed the optimal cut-point on the pWERCAP as a score of >30 (sensitivity: 0.89; specificity: 1.0). There was a significant negative correlation between aWERCAP scores and total cognition (R=-0.42), and between pWERCAP scores and sensorimotor processing speed. Total stress scores correlated significantly with scores on the aWERCAP (R=0.88), pWERCAP (R=0.62) and total cognition (R=-0.44). Our results show that the WERCAP Screen and the WERC Stress Screen are easy to administer and derived scores are related to cognitive and clinical traits. This suggests that their use could have particular benefits for epidemiologic studies and in busy clinical settings. Longitudinal studies would be required to evaluate clinical outcomes with high questionnaire scores. Copyright © 2014 Elsevier Inc. All rights reserved.

End-stage renal disease (ESRD) in children is associated with impaired neurocognitive function and development. However, data on factors associated with neurocognitive dysfunctions in children with kidney transplants are limited. We conducted a cross-sectional analysis comparing cognitive functions (using the Woodcock-Johnson International Edition, WJIE) in 35 kidney transplant and 35 healthy control children. Data on laboratory measurements, comorbidities, and social characteristics were collected. Transplant children had significantly worse scores on the intelligence quotient (IQ) test compared with controls [Full Scale IQ score 85 (26) vs 107 (10), p <0.001]. Lower maternal education level was significantly associated with lower WJIE cognitive test scores; however, no association was found between laboratory values and WJIE scores. Among children with kidney transplants, those with medical comorbid conditions had significantly lower Verbal Ability and Full Scale IQ scores. Earlier age of dialysis onset and a longer total time on dialysis (>9 months) were associated with lower test scores. Age-standardized duration of hospitalization was inversely correlated with IQ (r = -0.46, p <0.01) and was an independent significant predictor (Beta = -0.38, p = 0.02) of IQ scores in transplanted children. Child kidney transplant recipients have neurocognitive function impairments that are associated with markers of socioeconomic status (SES) and factors related to disease severity.

Background Evidence suggests that the urogenital pain of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) may be neuropathic. Methods This randomized, double-blind, placebo-controlled trial was conducted across 10 tertiary care centers in North America to determine whether pregabalin, which has been proved effective in other chronic pain syndromes, is effective in reducing CP/CPPS symptoms. In 2006–2007, 324 men with pelvic pain for at least 3 of the previous 6 months were enrolled in this study. Men were randomly assigned to receive pregabalin or placebo in a 2:1 ratio and were treated for 6 weeks. Pregabalin dosage was increased from 150 to 600 mg/d during the first 4 weeks. The primary outcome was a 6-point decrease in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score. Multiple secondary outcomes were assessed. Results Of 218 men assigned to receive pregabalin, 103 (47.2%) reported at least a 6-point decrease in the NIHCPSI total score at 6 weeks compared with 35.8% (38 of 106 men) assigned to receive placebo (P = .07, exact Mantel-Haenszel test, adjusting for clinical sites). Compared with the placebo group, men assigned to receive pregabalin experienced reductions in the NIH-CPSI total score and sub-scores (P < .05), a higher Global Response Assessment response rate (31.2% and 18.9%; P = .02), and improvement in total McGill Pain Questionnaire score (P = .01). Results for the other outcomes did not differ between groups. Conclusion Pregabalin therapy for 6 weeks was not superior to placebo use in the rate of a 6-point decrease (improvement) in the NIH-CPSI total score in men with CP/CPPS.

Tremor is a widespread phenomenon in human populations. Environmental factors are likely to play an etiological role. Harmane (1-methyl-9H-pyrido[3,4-β]indole) is a potent tremor-producing β-carboline alkaloid. Lead is another tremor-producing neurotoxicant. The effects of harmane and lead with respect to tremor have been studied in isolation. We tested the hypothesis that tremor would be particularly severe among individuals who had high blood concentrations of both of these toxicants. Blood concentrations of harmane and lead were each quantified in 257 individuals (106 essential tremor cases and 151 controls) enrolled in an environmental epidemiological study. Total tremor score (range = 0-36) was a clinical measure of tremor severity. The total tremor score ranged from 0 to 36, indicating that a full spectrum of tremor severities was captured in our sample. Blood harmane concentration correlated with total tremor score (p = 0.007), as did blood lead concentration (p = 0.045). The total tremor score was lowest in participants with both low blood harmane and lead concentrations (8.4 ± 8.2), intermediate in participants with high concentrations of either toxicant (10.5 ± 9.8), and highest in participants with high concentrations of both toxicants (13.7 ± 10.4) (p=0.01). Blood harmane and lead concentrations separately correlated with total tremor scores. Participants with high blood concentrations of both toxicants had the highest tremor scores, suggesting an additive effect of these toxicants on tremor severity. Given the very high population prevalence of tremor disorders, identifying environmental determinants is important for primary disease prevention. Copyright © 2010 Elsevier Inc. All rights reserved.

Research in primary health care (PHC) is underdeveloped and scarce, especially in developing countries. It is important to understand the attitudes and aspirations of PHC physicians for the promotion of research. The aim of this study was to determine the attitudes of PHC physician managers toward research in Qassim province and to identify barriers that impede performing research in the PHC system. The study was based on social cognitive theory framework, and was pre-experimental with a 'one-group pre-test-post-test' design. The study participants were physician managers in PHC administration, Qassim. The participants' attitudes were measured by adapting statements from the Attitude Towards Research scale. The intervention was the 1-day training program 'Introduction to Research in Primary Health Care'. A total of 23 PHC physicians participated in the study. The mean age of the participants was 45.4 (±1.6) years, and the mean years of work experience was 16.2 (±2.2) years. Only one participant had an article published in a peer-reviewed journal. The results of the study showed that PHC physicians had a baseline positive attitude toward research that was further enhanced after participating in an introductory research-training program. During the pre-test, out of the total score of 63, the mean score on attitude toward research was 48.35 (±6.8) while the mean total attitude score in the post-test was 49.7 (±6.6). However, the difference was not statistically significant at P<0.05. The item with the highest score regarded the role of research in the improvement of health care services, while the lowest-scoring item was about support from administration to conduct research. The participants recognised lack of skills, lack of training and inadequate resources as major barriers in conducting research. Our study results suggest that the PHC physicians' positive attitudes toward research can be further improved through in-service training. To promote research in PHC in Qassim, regular research-training programs and incentives for conducting research should be provided to the PHC physicians.

To identify the nutritional and immunological correlates of memory and neurocognitive development as measured by the Mullen Scales of Early Learning (MSEL) and by the Color Object Association Test (COAT) among children in Uganda. This analysis uses baseline data collected between 2008 and 2010 from 119 HIV-infected children aged 1-6 years, participating in a randomized controlled trial of an interventional parenting program in Kayunga, Uganda. Peripheral blood draws were performed to determine immunological biomarkers. Unadjusted and adjusted linear regression models were used to relate MSEL and COAT scores to sociodemographic characteristics, weight-for-age Z scores (WAZs), antiretroviral therapy status, and immunological biomarkers. In the final analysis, 111 children were included. Lower levels of CD4 CD38 T cells (P = 0.04) were associated to higher immediate and total recall scores (P = 0.04). Higher levels of CD8 HLA-DR T cells were associated with higher total recall score (P = 0.04) of the COAT. Higher CD4 CD38 HLA-DR T cells levels were associated with higher gross motor scores of the MSEL (P = 0.02). WAZ was positively correlated to visual reception, fine motor, expressive language, and composite score of the MSEL. Overall, WAZ was a stronger predictor of neurocognitive outcomes assessed by the MSEL. CD4 CD38 T cells were more specifically associated with memory-related outcomes. Future research should include immunological markers and standardized neurocognitive tests to further understand this relationship.

Objective To identify predictors of prolonged symptoms for athletes who sustain concussions. Study design We conducted a multi-center, prospective, cohort study of patients in 2 sport concussion clinics. Possible predictors of prolonged symptoms from concussion were compared between two groups: those whose symptoms resolved within 28 days and those whose symptoms persisted beyond 28 days. Candidate predictor variables were entered into a logistic regression model that was used to generate adjusted odds ratios. Results During the study period, 182 patients met inclusion criteria. The mean age was 15.2 years (SD 3.04 years). Over a third (N=65) of patients underwent computerized neurocognitive testing on their initial visit. In univariate analyses, Post Concussion Symptom Scale (PCSS) score and all composite scores on computerized neurocognitive testing appeared to be associated with prolonged symptom duration. Sex, age, loss of consciousness at time of injury and amnesia at time of injury were not associated with prolonged symptom duration. After adjusting for potential confounding, however, only total score on the PCSS score was associated with the odds of suffering prolonged symptoms. Conclusions After adjusting for other potential confounding variables, only total score on the PCSS was associated with the odds of suffering prolonged symptoms from sport-related concussions; age and amnesia were not. Further efforts to develop clinical tools for predicting which athletes will suffer prolonged recoveries after concussion should focus on initial symptom score. PMID:23628374

Experimental evidences have demonstrated that Nigella sativa Linn. seed (NS) has positive modulation effects on aged rats with memory impairments, prevents against hippocampal pyramidal cell loss and enhances consolidation of recall capability of stored information and spatial memory in rats. NS has neuroprotective, nephroprotective, lung protective, cardioprotective, hepatoprotective activities as established by previous studies on animals. Several clinical trials with NS on human have also demonstrated beneficial effect. The present study was designed to investigate the effects of NS on memory, attention and cognition in healthy elderly volunteers. Furthermore, safety profile of NS was assessed during the nine-week study period. Forty elderly volunteers were recruited and divided randomly into group A and group B--each consisting of 20 volunteers. The treatment procedure for group A was 500 mg NS capsule twice daily for nine weeks and Group B received placebo instead of NS in the similar manner. All the volunteers were assessed for neuropsychological state and safety profile twice before treatment and after nine weeks. The neuropsychological tests were logical memory test, digit span test, Rey-Osterrieth complex figure test, letter cancellation test, trail making test and stroop test. Safety profile was assessed by measuring biochemical markers of Cardiac (total cholesterol, triglycerides and high density lipoprotein cholesterol, very low density lipoprotein, low density lipoprotein cholesterol, creatine kinase-MB); Liver (aspartate aminotransferase, alanin aminotransferase, alkaline phosphatase, total protein, albumin, bilirubin) and Kidney (creatinine and blood urea nitrogen) through using commercial kits. There was significant difference (p<0.05) in the score of logical memory test-I and II, total score of digit span, 30 min delayed-recall, percent score in Rey-Osterrieth complex figure test, time taken to complete letter cancellation test, time taken in trail making test-A and test-B, score in part C of stroop test due to ingestion of NS for nine weeks. There were not statistically significant changes (p>0.05) in any of the biochemical markers of cardiac, liver, kidney function during this nine-week study period. The current study demonstrates the role of NS in enhancing memory, attention and cognition. Therefore, whether NS could be considered as potential food supplement for preventing or slow progressing of Alzheimer disease needs further investigations. However, study with Alzheimer's patients with large population size for longer period of time is recommended before using NS daily and extensive phytochemical investigations are recommended for novel drug discovery from NS for treating cognitive disorders.

LASIK is the use of excimer lasers to treat therapeutic and refractive visual disorders, ranging from superficial scars to nearsightedness (myopia), and from astigmatism to farsightedness (hyperopia). The purposes of this study are to checking the applicability and psychometric properties of the SERVQUAL on Lasik surgery population. Second, use SEM methods to investigate the loyalty, perceptions and expectations relationship on LASIK surgery. The method with which this study was conducted was questionnaire development. A total of 463 consecutive patients, attending LASIK surgery affiliated with Chung Shan Medical University Eye Center, enrolled in this study. All participants were asked to complete revised SERVQUAL questionnaires. Student t test, correlation test, and ANOVA and factor analyses were used to identify the characters and factors of service quality. Paired t test were used to test the gap between expectation and perception scores and structural equation modeling was used to examine relationships among satisfaction components. The effective response rate was 97.3%. Validity was verified by several methods and internal reliability Cronbach's alpha was > 0.958. The results from patient's scores were very high with an overall score of 6.41(0.66), expectations at 6.68(0.47), and perceptions at 6.51(0.57). The gap between expectations and perceptions was significant, however, (t = 6.08). Furthermore, there were significant differences in the expectation scores among the different jobs. Also, the results showed that the higher the education of the patient, the lower their perception score (r = -0.10). The factor loading results of factor analysis showed 5 factors of the 22 items of the SERVQUAL model. The 5 factors of perception explained 72.94% of the total variance there; and on expectations it explained 77.12% of the total variance of satisfaction scores.The goodness-of-fit summary, of structure equation modeling, showed trends in concept on expectations, perceptions, and loyalty. The results of this research appear to show that the SERVQUAL instrument is a useful measurement tool in assessing and monitoring service quality in LASIK service, and enabling staff to identify where improvements are needed, from the patients' perspective. There were service quality gaps in the reliability, assurance, and empathy. This study suggested that physicians should increase their discussions with patients; which has, of course, already been proven to be an effective way to increase patient's satisfaction with medical care, regardless of the procedure received.

Stress is one of the main causes of health problems, especially mental disorders. These health problems cause a significant amount of ability loss and increase cost. It is estimated that by 2020, mental disorders will constitute 15% of the total disease burden, and depression will rank second only after ischemic heart disease. Environmental experiences are paramount in increasing the liability of mental disorders in those who constantly face sustained high levels of stress. The objective of this study was to develop a stress scale for seasonal migrant agricultural workers aged 18 years and older. The sample consisted of 270 randomly selected seasonal migrant agricultural workers. The average age of the participants was 33.1 ± 14, and 50.7% were male. The Cronbach alpha coefficient and test-retest methods were used for reliability analyses. Although the factor analysis was performed for the structure validity of the scale, the Kaiser-Meyer-Olkin coefficient and Bartlett test were used to determine the convenience of the data for the factor analysis. In the reliability analyses, the Cronbach alpha coefficient of internal consistency was calculated as .96, and the test-retest reliability coefficient was .81. In the exploratory factor analysis for validity of the scale, four factors were obtained, and the factors represented workplace physical conditions (25.7% of the total variance), workplace psychosocial and economic factors (19.3% of the total variance), workplace health problems (15.2% of the total variance), and school problems (10.1% of the total variance). The four factors explained 70.3% of the total variance. As a result of the expert opinions and analyses, a stress scale with 48 items was developed. The highest score to be obtained from the scale was 144, and the lowest score was 0. The increase in the score indicates the increase in the stress levels. The findings show that the scale is a valid and reliable assessment instrument that can be used in epidemiological research and planning interventions.

Background Type 2 diabetes is a risk factor for development of cognitive dysfunction. Impairments in glucose regulation have been associated with poorer performance on tests of executive function and information processing speed. Methods We administered the Stroop Color Word Task, where higher interference scores are indicative of decreased selective attention, to 98 non-diabetic volunteers (64m; %fat=37±12; age=36±9 y, race=41 NA/30 C/13 H/14 AA) on our inpatient unit. After 3d on a weight maintaining diet, % body fat was measured by DXA and a 75g oral glucose tolerance test (OGTT) was administered. Impaired glucose regulation (IGR) was defined as: fasting plasma glucose ≥100 and ≤125 mg/dL and/or 2h plasma glucose between ≥140 and ≤199 mg/dL (IGR; n = 48; NGR; n = 50). Total and incremental area under the curve (AUC) for insulin and glucose were calculated. Results Stroop interference scores were not significantly associated with any measure of adiposity or insulin concentrations. Individuals with IGR had significantly higher interference scores than those with normal glucose regulation (NGR; p=0.003). Higher interference scores were significantly correlated with fasting plasma glucose concentrations (r=0.26, p = 0.007) and total glucose AUC (r=0.30, p = 0.02) and only trending so for iAUC and 2h plasma glucose (r=0.18, p=0.08; r=0.17, p=0.09 respectively). In separate multivariate linear models, fasting plasma glucose (p = 0.002) and total glucose AUC (p = 0.0005) remained significant predictors of Stroop interference scores, even after adjustment for age, sex, race, education and %fat. Conclusions Individuals with IGR had decreased performance on a test of selective attention. Fasting plasma glucose was more strongly associated with lower performance scores than 2h plasma glucose. Our results indicate that even mild hyperglycemia in the non-diabetic range is associated with attentional processing difficulties in a sample of younger adults. Whether these impairments precede or are induced by impaired glucose regulation is not clear. PMID:24036382

Recently, there are few studies reporting on depressive status and obstructive sleep apnoea (OSA) in China. A large-sample survey was to be performed to explore the prevalence of depressive status and related factors in Chinese patients with OSA. From among a randomly-selected group of OSA patients, 1,327 met inclusion criteria. After screening with the Symptom Checklist 90 (SCL-90) and Self-Rating Depression Scale (SDS), patients were assigned to OSA without depressive status (control group, n = 698) and OSA with depressive status (n = 629) groups. Using chi-squared testing, the correlation analyses between the depressive status and OSA patient demographic and clinical variables were tested. Then depression-related risk factors in OSA patients were analysed using stepwise linear regression analysis. The effects of family and social factors on depressive status in OSA patients were investigated using Mann-Whitney U (one of nonparametric test). The prevalence of depressive status was 47.4% in OSA patients. Depressive status was significantly associated with female gender, single status, Family Burden Scale of Disease (FBS), Family APGAR Index (APGAR), apnoea-hypopnea index (AHI), and Perceived Social Support Scale (PSSS). Stepwise linear regression analysis further indicated that single status, hypoxemia, APGAR, AHI, PSSS, AHI, and FBS were all risk factors for depressive status in OSA patients. The total of the FBS score and three of its sub-factors scores (family daily activities, family relationships and mental health of family members) were higher, and the total of the APGAR score and two of its sub-factors scores (adaptability and affection) were lower in OSA with depressive status compared with the control group. Besides, the total score for the PSSS and scores for its two sub-factors (family support and social support) were all lower in OSA patients with depressive status than those of the control group. Depressive status has high comorbid rate in Chinese OSA patients and is significantly associated with single status, apnoea-hypopnea index, hypoxemia, family and social supports.

The PedsQL 3.0 Cancer Module is a widely used instrument to measure pediatric cancer specific health-related quality of life (HRQOL) for children aged 2 to 18 years. We developed the Japanese version of the PedsQL Cancer Module and investigated its reliability and validity among Japanese children and their parents. Participants were 212 children with cancer and 253 of their parents. Reliability was determined by internal consistency using Cronbach's coefficient alpha and test-retest reliability using intra-class correlation coefficient (ICC). Validity was assessed through factor validity, convergent and discriminant validity, concurrent validity, and clinical validity. Factor validity was examined by exploratory factor analysis. Convergent and discriminant validity were examined by multitrait scaling analysis. Concurrent validity was assessed using Spearman's correlation coefficients between the Cancer Module and Generic Core Scales, and the comparison of the scores of child self-reports with those of other self-rating depression scales for children. Clinical validity was assessed by comparing the on- and off- treatment scores using Kruskal-Wallis and Mann-Whitney U tests. Cronbach's coefficient alpha was over 0.70 for the total scale and over 0.60 for each subscale by age except for the 'pain and hurt' subscale for children aged 5 to 7 years. For test-retest reliability, the ICC exceeded 0.70 for the total scale for each age. Exploratory factor analysis demonstrated sufficient factorial validity. Multitrait scaling analysis showed high success rates. Strong correlations were found between the reports by children and their parents, and the scores of the Cancer Module and the Generic Core Scales except for 'treatment anxiety' subscales for child reports. The Depression Self-Rating Scale for Children (DSRS-C) scores were significantly correlated with emotional domains and the total score of the cancer module. Children who had been off treatment over 12 months demonstrated significantly higher scores than those on treatment. The results demonstrate the reliability and validity of the Japanese version of the PedsQL Cancer Module among Japanese children.

The effect of chlorhexidine dihydrochloride (chlorhex HCl) in lozenges on plaque growth was assessed on 21 subjects with fresh plaque of 7 days duration. The lozenges, which contained 5 mg chlorhex HCl, were sucked three times daily after meals, for 2 weeks. The study was a single-blind crossover. Placebo lozenges had all the ingredients except chlorhex HCl. These were used as a control. Results indicated that lozenges containing chlorhex HCl were a potent plaque inhibitor. The mean plaque score was reduced by 62.8% from an initial mean plaque score (DO) of 2.38 +/- 0.48 to (D7) 0.89 +/- 0.26 (p less than 0.0001), after 1 wk of usage. A further reduction to plaque score (D14) of 0.56 +/- 0.27 (p less than 0.0001) was recorded by the end of the 2nd wk. Usage of the placebo during the same time period did not show significant differences in the plaque score (DO = 2.38; D7 = 2.33; D14 = 2.42). Inhibition of plaque formation to the 1104 test surfaces revealed a total elimination of the higher levels of plaque (scores 4 and 5), a considerable reduction of the middle levels (scores 2 and 3) and a significant increase (44.7%) of low level plaque (score 1). Total elimination of plaque (score 0) was observed in 50.3% of the test group surfaces. Lozenges containing 5 mg chlorhexidine dihydrochloride, taken three times daily, were an efficient, comfortable and potent agent for reducing and inhibiting plaque formation. These lozenges are a more convenient alternative to chlorhexidine mouthrinses and may prove to be superior to these.

Infants born preterm and/or with low birth weight may present a clinical condition of organic instability and usually face a long period of hospitalization in the Neonatal Intensive Care Units, being exposed to biopsychosocial risk factors to their development due to decreased spontaneous movement and excessive sensory stimuli. This study assumes that there are relationships between the integration of sensory information of preterm infants, motor development and their subsequent effects. To evaluate the sensory processing and motor development in preterm infants aged 4-6 months and compare performance data with their peers born at term. This was a cross-sectional and comparative study consisting of a group of preterm infants (n=15) and a group of term infants (n=15), assessed using the Test of Sensory Functions in Infants (TSFI) and the Alberta Infant Motor Scale (AIMS). The results showed no significant association between motor performance on the AIMS scale (total score) and sensory processing in the TSFI (total score). However, all infants who scored abnormal in the total TSFI score, subdomain 1, and subdomain 5 presented motor performance at or below the 5th percentile on the AIMS scale. Since all infants who presented definite alteration in tolerating tactile deep pressure and poor postural control are at risk of delayed gross motor development, there may be peculiarities not detected by the tests used that seem to establish some relationship between sensory processing and motor development.

Background/Aims: We prepared a cross-cultural adaptation of the Behcet’s Syndrome Activity Scale (BSAS) and evaluated its reliability and validity in Korea. Methods: Fifty patients with Behcet’s disease (BD) who attended the Rheumatology Clinic of Gachon University Gil Medical Center were included in this study. The first BSAS questionnaire was administered at each clinic visit, and the second questionnaire was completed at home within 24 hours of the visit. A Behcet’s Disease Current Activity Form (BDCAF) and a Behcet’s Disease Quality of Life (BDQOL) form were also given to patients. The test-retest reliability was analyzed by intraclass correlation coefficients (ICC). To assess the validity, the total BSAS score was compared with the BDCAF score, the patient/physician global assessment, and the BDQOL by Spearman rank correlation. Results: Twelve males and 38 females were enrolled. The mean age was 48.5 years and the mean disease duration was 6.7 years. Thirty-eight patients (76.0%) returned the questionnaire by mail. For the test-retest reliability, the two assessments were significantly correlated on all 10 items of the BSAS questionnaire (p < 0.05) and the total BSAS score (ICC, 0.925; p < 0.001). The total BSAS score was statistically correlated with the BDQOL, BDCAF, and patient/physician global assessment (p < 0.01). Conclusions: The Korean version of BSAS is a reliable and valid instrument to measure BD activity. PMID:26767871

Objective To investigate the cognitive impairment in patients with age-related macular degeneration (AMD). Methods Relevant articles were identified through a search of the following electronic databases through October 2015, without language restriction: 1) PubMed; 2) the Cochrane Library; 3) EMBASE; 4) ScienceDirect. Meta-analysis was conducted using STATA 12.0 software. Standardized mean differences with corresponding 95% confidence intervals were calculated. All of the included studies met the following four criteria: 1) the study design was a case–control or randomized controlled trial (RCT) study; 2) the study investigated cognitive function in the patient with AMD; 3) the diagnoses of AMD must be provided; 4) there were sufficient scores data to extract for evaluating cognitive function between cases and controls. The Newcastle–Ottawa Scale criteria were used to assess the methodological quality of the studies. Results Of the initial 278 literatures, only six case–control and one RCT studies met all of the inclusion criteria. A total of 794 AMD patients and 1,227 controls were included in this study. Five studies were performed with mini-mental state examination (MMSE), two studies with animal fluency, two studies with trail making test (TMT)-A and -B, one study with Mini-Cog. Results of the meta-analysis revealed lower cognitive function test scores in patients with AMD, especially with MMSE and Mini-Cog test (P≤0.001 for all). The results also showed that differences in the TMT-A (except AMD [total] vs controls) and TMT-B test had no statistical significance (P>0.01). The Newcastle–Ottawa Scale score was ≥5 for all of the included studies. Based on the sensitivity analysis, no single study influenced the overall pooled estimates. Conclusion This meta-analysis suggests lower cognitive function test scores in patients with AMD, especially with MMSE and Mini-Cog test. The other cognitive impairment screening tests, such as animal fluency test and TMT, need more studies to assess. PMID:26966358

Simulation-based education has been integrated into many orthopaedic residency programs to augment traditional teaching models. Here we describe the development and implementation of a combined didactic and simulation-based course for teaching medical students and interns how to properly perform a closed reduction and percutaneous pinning of a pediatric supracondylar humeral fracture. Subjects included in the study were either orthopaedic surgery interns or subinterns at our institution. Subjects all completed a combined didactic and simulation-based course on pediatric supracondylar humeral fractures. The first part of this course was an electronic (e)-learning module that the subjects could complete at home in approximately 40 minutes. The second part of the course was a 20-minute simulation-based skills learning session completed in the simulation center. Subject knowledge of closed reduction and percutaneous pinning of supracondylar humeral fractures was tested using a 30-question, multiple-choice, written test. Surgical skills were tested in the operating room or in a simulated operating room. Subject pre-intervention and post-intervention scores were compared to determine if and how much they had improved. A total of 21 subjects were tested. These subjects significantly improved their scores on both the written, multiple-choice test and skills test after completing the combined didactic and simulation module. Prior to the module, intern and subintern multiple-choice test scores were significantly worse than postgraduate year (PGY)-2 to PGY-5 resident scores (p < 0.01); after completion of the module, there was no significant difference in the multiple-choice test scores. After completing the module, there was no significant difference in skills test scores between interns and PGY-2 to PGY-5 residents. Both tests were validated using the scores obtained from PGY-2 to PGY-5 residents. Our combined didactic and simulation course significantly improved intern and subintern understanding of supracondylar humeral fractures and their ability to perform a closed reduction and percutaneous pinning of these fractures.

To investigate the effect of postsurgical pain on the performance of horses in a novel object and auditory startle task. Prospective clinical study. Twenty horses undergoing different types of surgery and 16 control horses that did not undergo surgery. The interaction of 36 horses with novel objects and a response to an auditory stimulus were measured at two time points; the day before surgery (T1) and the day after surgery (T2) for surgical horses (G1), and at a similar time interval for control horses (G2). Pain and sedation were measured using simple descriptive scales at the time the tests were carried out. Total time or score attributed to each of the behavioural categories was compared between groups (G1 and G2) for each test and between tests (T1 and T2) for each group. The median (range) time spent interacting with novel objects was reduced in G1 from 58 (6-367) seconds in T1 to 12 (0-495) seconds in T2 (p=0.0005). In G2 the change in interaction time between T1 and T2 was not statistically significant. Median (range) total auditory score was 7 (3-12) and 10 (1-12) in G1 and G2, respectively, at T1, decreasing to 6 (0-10) in G1 after surgery and 9.5 (1-12) in G2 (p=0.0003 and p=0.94, respectively). There was a difference in total auditory score between G1 and G2 at T2 (p=0.0169), with the score being lower in G1 than G2. Postsurgical pain negatively impacts attention towards novel objects and causes a decreased responsiveness to an auditory startle test. In horses, tasks demanding attention may be useful as a biomarker of pain. Copyright © 2017 Association of Veterinary Anaesthetists and American College of Veterinary Anesthesia and Analgesia.

Clinical measurement. To translate and cross-culturally adapt the Hip disability and Osteoarthritis Outcome Score (HOOS) from English into German, and to study its psychometric properties in patients after hip surgery. There is no specific hip questionnaire in German that not only measures symptoms and function but also contains items about hip-related quality of life. The translation and cross-cultural adaptation involved forward translation, harmonization, cognitive debriefing, back translation, and comparison to the original HOOS following international guidelines. The German version was tested in 51 Swiss inpatients 8 weeks after different types of hip surgery, mainly total hip replacement. The mean age of the participants was 62.5 years, and the age range was from 27 to 87 years. Thirty (58.8%) of the participants were women. Internal consistency and test-retest reliability were estimated using Cronbach alpha and intraclass correlation coefficients for agreement. For construct validity, total scores of the German HOOS were correlated with those of the Western Ontario and McMaster Universities Osteoarthritis Index. The HOOS was also compared to the Medical Outcomes Study 36-Item Short-Form Health Survey. Cronbach alpha values for all German HOOS subscales were between .87 and .93. For test-retest reliability, the intraclass correlation coefficient for agreement was 0.85 for the total scores of the German HOOS. The Spearman rho for the Medical Outcomes Study 36-Item Short-Form Health Survey physical functioning subscale compared to the sum of all HOOS subscales was 0.71, and that for the Medical Outcomes Study 36-Item Short-Form Health Survey physical component summary was 0.97. The German HOOS has demonstrated adequate reliability and validity. Use of the German HOOS is recommended for assessment of patients after hip surgery, with the proviso that additional psychometric testing should be done in future research.

The aim of our study was to translate and to do a linguistic validation of the Composite Autonomic Symptom Score COMPASS 31. COMPASS 31 is a self-assessment instrument including 31 items assessing six domains of autonomic functions: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor functions. This questionnaire has been created by the Autonomic group of the Mayo Clinic from two previous versions: the Autonomic Symptom Profile (ASP) composed of 169 items and the following COMPASS with 72 items selected from the ASP. We translated the questionnaire by means of a standardized forward and back-translation procedure. Thirty-six subjects, 25 patients with autonomic failure of different aethiologies and 11 healthy controls filled in the COMPASS 31 twice, 4 ± 1 weeks apart, once in Italian and once in English in a randomized order. The test-retest showed a significant correlation between the Italian and the English versions as total score. The evaluation of single domains by means of Pearson correlation when applicable or by means of Spearman test showed a significant correlation between the English and the Italian COMPASS 31 version for all clinical domains except the vasomotor one for the lack of scoring. The comparison between the patients with autonomic failure and healthy control groups showed significantly higher total scores in patients with respect to controls confirming the high sensitivity of COMPASS 31 in revealing autonomic symptoms.

Balance testing is an important part of the initial concussion assessment. There is no research on the differences in Modified Balance Error Scoring System (M-BESS) scores when tested in real world as compared to control conditions. To assess the difference in M-BESS scores in athletes wearing their protective equipment and cleats on different surfaces as compared to control conditions. This cross-sectional study examined university North American football and soccer athletes. Three observers independently rated athletes performing the M-BESS test in three different conditions: (1) wearing shorts and T-shirt in bare feet on firm surface (control); (2) wearing athletic equipment with cleats on FieldTurf; and (3) wearing athletic equipment with cleats on firm surface. Mean M-BESS scores were compared between conditions. 60 participants were recruited: 39 from football (all males) and 21 from soccer (11 males and 10 females). Average age was 21.1 years (SD=1.8). Mean M-BESS scores were significantly lower (p<0.001) for cleats on FieldTurf (mean=26.3; SD=2.0) and for cleats on firm surface (mean=26.6; SD=2.1) as compared to the control condition (mean=28.4; SD=1.5). Females had lower scores than males for cleats on FieldTurf condition (24.9 (SD=1.9) vs 27.3 (SD=1.6), p=0.005). Players who had taping or bracing on their ankles/feet had lower scores when tested with cleats on firm surface condition (24.6 (SD=1.7) vs 26.9 (SD=2.0), p=0.002). Total M-BESS scores for athletes wearing protective equipment and cleats standing on FieldTurf or a firm surface are around two points lower than M-BESS scores performed on the same athletes under control conditions.

Effective use of patient-rated outcome measures to facilitate optimal patient care requires an understanding of the reference values of these measures within the population of interest. Little is known about reference values for commonly used patient-rated outcome measures in adolescent athletes. To determine reference values for the Pediatric Quality of Life Inventory (PedsQL) and the Multidimensional Fatigue Scale (MFS) in adolescent athletes by sport and sex. Cross-sectional study; Level of evidence, 3. A convenience sample of interscholastic adolescent athletes from 9 sports was used. Participants completed the PedsQL and MFS during one testing session at the start of their sport season. Data were stratified by sport and sex. Dependent variables included the total PedsQL score and the 5 PedsQL subscale scores: physical functioning, psychosocial functioning, emotional functioning, social functioning, and school functioning. Dependent variables for the MFS included 3 subscale scores: general functioning, sleep functioning, and cognitive functioning. Summary statistics were reported for total and subscale scores by sport and sex. Among 3574 males and 1329 female adolescent athletes, the PedsQL scores (100 possible points) generally indicated high levels of health regardless of sport played. Mean PedsQL total and subscales scores ranged from 82.6 to 95.7 for males and 83.9 to 95.2 for females. Mean MFS subscale scores (100 possible points) ranged from 74.2 to 90.9 for males and 72.8 to 87.4 for females. Healthy male and female adolescent athletes reported relatively high levels of health on the PedsQL subscales and total scores regardless of sport; no mean scores were lower than 82.6 points for males or 83.9 points for females. On the MFS, males and females tended to report low effect of general and cognitive fatigue regardless of sport; mean scores were higher than 83.5 points for males and 83.8 points for females. Clinically, athletes who score below the reference values for their sport have poorer health status than average adolescent athletes participating in that sport. Scores below reference values may warrant consideration of early intervention or treatment.

We present a prospective series of tuberculum sellae meningioma (TSM) resected via a superior interhemispheric (IH) approach in 10 patients who preoperatively and postoperatively underwent extensive olfaction testing using a standardised test battery. This prospective longitudinal study evaluated the olfactory function after TSM resection. The resection was performed via a superior interhemispheric (IH) approach. The quantitative and qualitative analyses of the olfactory function were assessed with the Biolfa(®) olfactory test (at 6 months). Between November 2009 and April 2012, 10 consecutive patients with symptomatic TSM and preserved olfactory function were operated via a superior IH approach. For the self-evaluation criteria of the olfactory function, the mean preoperative visual analog scale score was 8.8. The mean preoperative total quantitative (/27) scored 18.2 ± 6.3 for this cohort of 10 patients. In the postoperative period, the mean total score decreased non-significantly to 15.8 ± 8.8 (Wilcoxon test, P = 0.085). The mean preoperative qualitative score (/8) was 5.5 ± 1.7 and in the postoperative period decreased, non-significantly, to 4.7 ± 2.6 (Wilcoxon test, P = 0.12). The olfactory function was quantitatively and qualitatively preserved in 6 patients (60%), but a postoperative deterioration occurred in 2 (20%) and an anosmia in 2 (20%). Size and invasive characteristics of the meningioma determined the post-surgical deterioration. Olfaction is an important factor of emotional and social life, which needs to be integrated into the challenge regarding the resection of TSM. The risks of nerve damage are reviewed.

The University of California San Francisco (UCSF) Screening Battery provides clinicians with a uniquely tailored tool to measure ALS patients' cognitive and behavioral changes, adjusting for dysarthria and hand weakness. The battery consists of the ALS-CBS ( 1 ), Written Fluency Test ( 2 ), and a new revision of the Frontal Behavior Inventory (FBI-ALS) ( 3 ). The validity of each component was tested by comparing results with a gold standard neuropsychological exam (GNE). Consensus criteria-based GNE diagnoses ( 4 ) were assigned (n = 24) and concurrent validity was tested for each screening exam component. Results showed that each of the four cognitive and behavioral screening test components were significantly associated with diagnoses confirmed by GNE. GNE diagnoses were significantly associated with FBI-ALS negative score, written S-words score, and ALS-CBS cognitive score. The total FBI-ALS score and C-words tests were less predictive of GNE-diagnosed impairment. In conclusion, the UCSF Cognitive Screening Battery demonstrates good external validity compared with GNE in this modest sample, encouraging its use in larger investigations. These data suggest that this battery may provide an effective screen to identify ALS patients who will then benefit from a full examination to confirm their diagnosis.

2013-01-01

Objective: This study was a comparative investigation of the clinical efficacy and safety of intramuscular (IM) olanzapine and IM haloperidol in agitated elderly patients with schizophrenia at 2 hours postdose. Methods: The subjects were 23 inpatients who had been diagnosed with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Their clinical symptoms were assessed using Positive and Negative Syndrome Scale Excited Component (PANSS-EC), PANSS and Agitation Calmness Evaluation Scale (ACES), and their safety were assessed using the Abnormal Involuntary Movement Scale (AIMS), Barnes Akathisia Rating Scale (BARS), Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) and laboratory tests. Results: The mean reduction from baseline on the PANSS-EC total score, the PANSS total score and the ACES score were significantly greater in the IM olanzapine injection group than in the IM haloperidol injection group. The mean changes from baseline on the AIMS score, the BARS score and the DIEPSS total score were significantly better in the IM olanzapine injection group than in the IM haloperidol injection group. No serious adverse events such as paralytic ileus, diabetic ketoacidosis, neuroleptic malignant syndrome or tardive dyskinesia occurred between the two groups. Conclusion: The results of this study suggest the possibility that agitated elderly patients may result in superior efficacy and safety after IM olanzapine without serious adverse events in comparison with IM haloperidol.

The aim of this study was to explore the effects of brexpiprazole and aripiprazole on efficacy, cognitive functioning, and safety in patients with acute schizophrenia. Patients who would benefit from hospitalization/continued hospitalization for acute relapse of schizophrenia were enrolled and randomized (2 : 1) to target doses of open-label brexpiprazole 3 mg/day or aripiprazole 15 mg/day for 6 weeks. Outcomes included change from baseline to week 6 in the Positive and Negative Syndrome Scale total score, Barratt Impulsiveness Scale 11-item score, and Cogstate computerized cognitive test battery scores. Patients treated with brexpiprazole (n=64) or aripiprazole (n=33) showed reductions in symptoms of schizophrenia as assessed by Positive and Negative Syndrome Scale total score (-22.9 and -19.4, respectively). A modest reduction in impulsivity was observed with brexpiprazole, but not aripiprazole (mean change in the Barratt Impulsiveness Scale 11-item total score: -2.7 and 0.1, respectively). No change in Cogstate scores was observed for either treatment. Brexpiprazole was well tolerated and the incidence of akathisia was lower in patients treated with brexpiprazole (9.4%) than aripiprazole (21.2%). Clinically relevant improvements in psychopathology were observed in patients with acute schizophrenia treated with brexpiprazole or aripiprazole. Brexpiprazole was well tolerated, with a lower incidence of akathisia than aripiprazole.

To validate the Narcolepsy Severity Scale (NSS), a brief clinical instrument to evaluate the severity and consequences of symptoms in patients with narcolepsy type 1 (NT1). A 15-item scale to assess the frequency and severity of excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, sleep paralysis, and disrupted nighttime sleep was developed and validated by sleep experts with patients' feedback. Seventy untreated and 146 treated adult patients with NT1 were evaluated and completed the NSS in a single reference sleep center. The NSS psychometric properties, score changes with treatment, and convergent validity with other clinical parameters were assessed. The NSS showed good psychometric properties with significant item-total score correlations. The factor analysis indicated a 3-factor solution with good reliability, expressed by satisfactory Cronbach α values. The NSS total score temporal stability was good. Significant NSS score differences were observed between untreated and treated patients (dependent sample, 41 patients before and after sleep therapy; independent sample, 29 drug-free and 105 treated patients). Scores were lower in the treated populations (10-point difference between groups), without ceiling effect. Significant correlations were found among NSS total score and daytime sleepiness (Epworth Sleepiness Scale, Mean Sleep Latency Test), depressive symptoms, and health-related quality of life. The NSS can be considered a reliable and valid clinical tool for the quantification of narcolepsy symptoms to monitor and optimize narcolepsy management. © 2017 American Academy of Neurology.

Fatigue is a common symptom in post-polio syndrome (PPS) and can have a substantial impact on patients. There is a need for validated questionnaires to assess fatigue in PPS for use in clinical practice and research. The aim with this study was to assess the validity and reliability of the Swedish version of Multidimensional Fatigue Inventory (MFI-20) in patients with PPS using the Rasch model. A total of 231 patients diagnosed with PPS completed the Swedish MFI-20 questionnaire at post-polio out-patient clinics in Sweden. The mean age of participants was 62 years and 61% were females. Data were tested against assumptions of the Rasch measurement model (i.e. unidimensionality of the scale, good item fit, independency of items and absence of differential item functioning). Reliability was tested with the person separation index (PSI). A transformation of the ordinal total scale scores into an interval scale for use in parametric analysis was performed. Dummy cases with minimum and maximum scoring were used for the transformation table to achieve interval scores between 20 and 100, which are comprehensive limits for the MFI-20 scale. An initial Rasch analysis of the full scale with 20 items showed misfit to the Rasch model (p < 0.001). Seven items showed slightly disordered thresholds and person estimates were not significantly improved by rescoring items. Analysis of MFI-20 scale with the 5 MFI-20 subscales as testlets showed good fit with a non-significant x (2) value (p = 0.089). PSI for the testlet solution was 0.86. Local dependency was present in all subscales and fit to the Rasch model was solved with testlets within each subscale. PSI ranged from 0.52 to 0.82 in the subscales. This study shows that the Swedish MFI-20 total scale and subscale scores yield valid and reliable measures of fatigue in persons with post-polio syndrome. The Rasch transformed total scores can be used for parametric statistical analyses in future clinical studies.

Breast cancer (BC) is the most common female malignancy in the world and Turkey. Its prevalence and mortality are surprisingly increasing at a rapid rate. The objective of this study was to determine the effectiveness of training sessions on women's knowledge of relevant risk factors of BC and screening methods, screening behaviors and health beliefs among of healthy women in Turkey. In this study, in order to establish the efficiency of BC training, a semi-empirical single group pre-test & post-test research model was used. The data were collected by using a self-administered questionnaire and by using the Turkish version of Champion's health belief model scale (CHBMS). The pre-test was performed before the training and after one week of the training, post-test was performed with a questionnaire having the same content. In total, 244 women participated in the study. The average age of the women was 39.44 (SD=1.06) years. The mean total knowledge score increased significantly (p<.001) from 9.05 in the pre-test to 16.53 in the post-test. The results showed that both mean knowledge scores and CHBMS subscales scores of the women were increased significantly (p<.001) from the pre-test to the post-test. In multiple linear regression analysis, BC screening knowledge of women with susceptibility, benefit, self-efficacy and health motivation subscales of CHBMS, breast self-examination (BSE) practice and self-efficacy were also significant in the post-test; in the pre- and post-tests, a significant relationship among the level of education of women, susceptibility and seriousness was found (p<.001). The study showed that the training program had profound effects on BC knowledge, screening behaviors and health beliefs of women.

Internal Medicine residents must develop competency as Primary Care Providers, but a gap exists in their curriculum and training with regard to women's reproductive health. With increasing need in VA due to new influx of women veterans it poses problems in recruitment of competent physicians trained in Women's health. An intensive, one-month women's reproductive health curriculum with hands on experience for Internal Medicine residents was provided. Curriculum was taught to the residents who rotated at the Women's Health Clinic for one month. Pre-test and post-test exams were administered. Increase in knowledge of residents in providing gender specific evaluations and management was objectively assessed by changes in post-test scores. Data were analyzed for statistically significant improvement in written tests scores. Total of 47 Internal Medicine residents rotated through Women's Health Center during the evaluation period. All residents completed both pre-test and post-test exams. The average time to complete the pre-test was 20.5 ± 5.4 min and 19.5 ± 4.8 min for post-test. There was no correlation between the time to complete the pre-test exam and the post-test exam. The total score was significantly improved from 8.5 ± 1.6 to 13.2 ± 1.8 (p < 0.0001). This study shows how to equip physicians in training with information on women's health that enables them to provide safe and gender appropriate care in primary care settings. This practice will reduce the need for frequent referrals for specialized care and thus provide cost saving for patient and health care on the whole.

The Pasquotank River Watershed covers 450 sq miles in the Coastal Plain of NE North Carolina. It flows from the Great Dismal Swamp at the VA/NC border into the Albemarle Sound. The watershed provides a transition between spawning grounds and waters of the Albemarle Sound. Forested swamp wetlands border much of the waterways. Increased agricultural and urban development has greatly affected water quality during recent years. Test were completed along the tributaries and the river itself, adding to the previously data from 2011, 2013, and 2014. Streams tested were the Newbegun Creek, Knobbs Creek, Areneuse Creek, Mill Dam Creek, and Sawyers Creek. These streams cover a large area of the watershed and provide a wide variety of shore development from swampland and farmland to industrial development. Samples were tested for pH, salinity, total dissolved solids, and conductivity. Air/water temperature, dissolved oxygen, wind speed/direction, and turbidity/clarity measurements were taken in the field. The results were placed into an online database and correlated to the location of the sample using Google Maps®. Analysis tools were developed to compare the data from all years. Excel spreadsheets were developed to look more closely at individual points and tests for each point. This database was connected to a data visualization page utilizing Google Maps®. The results show variations for the individual water quality scores, but the overall water quality score for all the tested water sources remained at a comparable level from previous years. Mill Dam Creek rose above the previous three scores of 48 (2011), 47 (2013), and 49 (2014) and achieved a medium water quality score of 57. Areneuse Creek improved in water quality with a medium water quality score of 60. Sawyers Creek became the lowest scoring waterway tested at 35. Knobbs Creek decreased from previous years with a water quality score of 42. For a fourth consecutive testing year, Newbegun Creek fell within the medium water quality range with a score of 65. Pasquotank River rose from the previous testing year's score of 35 but still remained within the bad water quality range with a score of 45. The Lower Pasquotank remained the highest scoring tributary for a second consecutive year with a score of 85. Team included authors plus Ricky Dixon and Raveen McKenzie of MVSU.

To examine the effects of an eight-month exercise training programme with Greek traditional dancing on functional capacity and quality of life in patients with schizophrenia. Randomized controlled trial. Sports Medicine Laboratory. A total of 31 patients, aged 59.9 ± 14.1 years. They were randomly assigned either to a Greek traditional dancing programme (Group A) or to a sedentary control group (Group B). A functional capacity assessment was performed at baseline and the end of the study. Global Assessment of Functioning Scale and Positive and Negative Syndrome Scale were also used. Quality of life was examined using the Quality of Life and Satisfaction questionnaire. After the eight months, Group A increased walking distance in the 6-minute walk test (328.4 ± 35.9 vs. 238.0 ± 47.6 m), sit-to-stand test (19.1 ± 1.8 vs. 25.1 ± 1.4 seconds), Berg Balance Scale score (53.1 ± 2.1 vs. 43.2 ± 6.7), lower limbs maximal isometric force (77.7 ± 25.7 vs. 51.0 ± 29.8 lb), Positive and Negative Syndrome Scale total score (77.0 ± 23.1 vs. 82.0 ± 24.4), Global Assessment of Functioning Scale total score (51.3 ± 15.5 vs. 47.7 ± 13.3) and Quality of Life total score (34.9 ± 5.2 vs. 28 ± 4.5), compared with Group B. Our results demonstrate that Greek traditional dances improve functional capacity and quality of life in patients with schizophrenia. © The Author(s) 2014.

The Center for Epidemiologic Studies Depression Scale (CES-D) is a widely used self-report measure of depression symptomatology. This study evaluated the reliability, validity, and measurement invariance of the CES-D 10 in a diverse cohort of Hispanics/Latinos from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). The sample consisted of 16,415 Hispanic/Latino adults recruited from four field centers (Miami, FL; San Diego, CA; Bronx, NY; Chicago, IL). Participants completed interview administered measures in English or Spanish. The CES-D 10 was examined for internal consistency, test-retest reliability, convergent validity, and measurement invariance. The total score for the CES-D 10 displayed acceptable internal consistencies (Cronbach α’s = .80 – .86) and test-retest reliability (r’s = .41 – .70) across the total sample, language group and ethnic background group. The total CES-D 10 scores correlated in a theoretically consistent manner with the Spielberger State-Trait Anxiety Inventory (r = .72, p < .001), the Patient Health Questionnaire-9 depression measure (r = .80, p < .001) the Short Form-12’s Mental Component Summary (r = −.65, p < .001) and Physical Component Summary score (r = −.25, p < .001). A confirmatory factor analysis showed that a one-factor model fit the CES-D 10 data well (CFI = .986, RMSEA = .047) after correlating one pair of item residual variances. Multiple group analyses showed the one-factor structure to be invariant across English and Spanish speaking responders and partially invariant across Hispanic/Latino background groups. The total score of the CES-D 10 can be recommended for use with Hispanics/Latinos in English and Spanish. PMID:27295022

To explore intelligence quotient in boys with primary nocturnal enuresis compared with normal boys considering their socioeconomic status. A total of 152 school-aged boys (including 55 boys with primary nocturnal enuresis and 97 matched normal controls) were assessed. Boys with a history of any neurological or urological disease were excluded. Two different districts of Tehran: Khani-Abad (a poor district) and Pirouzi (a middle class district) districts were enrolled according to socioeconomic status data reported by the World Health Organization. Intelligence tests were carried out using a validated Iranian translation of the Wechsler Intelligence Scale for Children Revised. Total, as well as performance intelligence quotient and verbal intelligence quotient scores and verbal-performance discrepancy (the difference between verbal and performance intelligence quotient scores for each individual) were compared using a t-test between boys with primary nocturnal enuresis in each district and their matched controls. Considering each district separately, the total intelligence quotient score was lower in primary nocturnal enuresis cases than controls only in the lower income district (90.7 ± 23.3 vs 104.8 ± 14.7, P = 0.002). Similarly, boys with primary nocturnal enuresis ranked lower in verbal intelligence quotient (P = 0.002) and performance intelligence quotient (P = 0.004) compared with their matched normal controls only in lower income district, whereas in the higher income district, boys with primary nocturnal enuresis ranked similar in total intelligence quotient to their matched controls. Boys with primary nocturnal enuresis had a lower intelligence quotient compared with the control participants only in low-income district. It seems important to adjust the results of the intelligence quotient assessment in these children according to their socioeconomic status. © 2017 The Japanese Urological Association.

The Leicester Cough Questionnaire (LCQ) has been validated in non-cystic fibrosis bronchiectasis (NCFBC). The present study aimed to create and validate a Spanish version of the LCQ (LCQ-Sp) in NCFBC. The LCQ-Sp was developed following a standardized protocol. For reliability, we assessed internal consistency and the change in score over a 15-day period in stable state. For responsiveness, we assessed the change in scores between visit 1 and the first exacerbation. For validity, we evaluated convergent validity through correlation with the Saint George's Respiratory Questionnaire (SGRQ) and discriminant validity. Two hundred fifty-nine patients (118 mild bronchiectasis, 90 moderate bronchiectasis and 47 severe bronchiectasis) were included. Internal consistency was high for the total scoring and good for the different domains (Cronbach's α: 0.86-0.91). The test-retest reliability shows an intraclass correlation coefficient of 0.87 for the total score. The mean LCQ-Sp score at visit 1 decreased at the beginning of an exacerbation (15.13 ± 4.06 vs. 12.24 ± 4.64; p < 0.001). The correlation between LCQ-Sp and SGRQ scores was -0.66 (p < 0.01). The differences in the LCQ-Sp total score between the different groups of severity were significant (p < 0.001). The LCQ-Sp discriminates disease severity, is responsive to change when faced with exacerbations and is reliable for use in bronchiectasis. © The Author(s) 2016.

Previous clinical studies found that yokukansan has a therapeutic effect on behavioral and psychological symptoms of dementia (BPSD) in dementia patients. To perform an updated meta-analysis of randomized controlled trials (RCTs) testing yokukansan for patients with BPSD. Primary efficacy and safety endpoints were BPSD total scores and all-cause discontinuation, respectively. Secondary outcomes were BPSD subscales, cognitive function scores [Mini-mental state examination (MMSE)], activities of daily living (ADL) scores, discontinuation due to adverse events (AEs), and incidences of AEs. Five RCTs with 381 patients with BPSD were included. Compared with controls [placebo+usual care (UC)], yokukansan significantly decreased BPSD total scores [standardized mean difference (SMD) = -0.32, 95% confidence interval (CI) = -0.53 to -0.11, p = 0.003, I2 = 0%, N = 5 studies, n = 361]. Yokukansan was more efficacious in reducing BPSD subscale scores (delusions: SMD = -0.51, 95% CI = -0.98 to -0.04, hallucinations: SMD = -0.54, 95% CI = -0.96 to -0.12, agitation/aggression: SMD = -0.37, 95% CI = -0.60 to -0.15) than placebo+UC. However, yokukansan was not superior to placebo+UC for BPSD total as well as any subscales scores only in Alzheimer's disease patients. Compared with UC, yokukansan treatment improved ADL scores (SMD = -0.32, 95% CI = -0.62 to -0.01). MMSE scores did not differ between the yokukansan and placebo+UC treatment groups. No significant differences were found in all-cause discontinuation, discontinuation due to AEs, and incidences of AEs between yokukansan and placebo+UC treatments. Our results suggest that yokukansan is beneficial for the treatment of patients with BPSD and is well-tolerated; it was not beneficial for BPSD total and any subscale scores only in Alzheimer's disease patients.

The impact of a balanced science pedagogical approach to scores on the Texas Assessment of Knowledge and Skills

Murray, Judith L.

This applied dissertation was designed to investigate whether a science curriculum using a balance between inquiry methodologies and vocabulary instruction would increase student achievement as measured by the Texas Assessment of Knowledge and Skills test. Fifth grade students' science test scores were analyzed from two successive school years. The first year, an inquiry only methodology was used in the study. The second year, a balanced curriculum approach, where inquiry methods were balanced with vocabulary instruction, was implemented in the classrooms. Results were analyzed for the total population, as well as the subpopulations of Hispanic, low socioeconomic, and gender. Analysis of the data revealed statistically significant gains for the total population of students and female students. However, these same gains did not occur in the Hispanic and low socioeconomic student populations.

The Panic Disorder Severity Scale (PDSS) is a well-established measure of panic symptoms but few data exist on this instrument in non north-American samples. Our main goal was to assess the psychometric properties (internal consistency, test re-test reliability, inter-rater reliability, convergent and divergent validity) and the factor structure of the Spanish version. Ninety-four patients with a main diagnosis of panic disorder were assessed with the Spanish version of PDSS, the Anxiety Sensitivity Index-3 (ASI-3), the Panic and Agoraphobia Scale (PAS), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory-II (BDI-II) the PDSS self-rating form and the Clinical Global Impression-Severity scale (CGI). The Spanish PDSS showed acceptable internal consistency (α = .74), excellent test-retest (total score and items 1-6: α > .58, p .90) and medium to large convergent validity (r = .68, 95% CI [.54, .79], p < .01; r = .80, 95% CI [.70, .87], p < .01; r = .48, 95% CI [.28, .67], p < .01; BAI, PAS and ASI-3 total scores respectively). Data on divergent validity (BDI-II total score: r = .52, 95% CI [.34, .67], p < .01) suggest some need for refinement of the PDSS. The confirmatory factor analysis suggested a two-factor modified model for the scale (nested χ2 = 14.01, df = 12, p < .001). The Spanish PDSS has similar psychometric properties as the previous versions and is a useful instrument to assess panic symptoms in clinical settings in Spanish-speaking populations.

Background and Aims Caregiver stress is often a serious problem when caring for a patient with frontal lobe dysfunction. Methods A total of 102 caregivers of both patients with frontotemporal degeneration and corticobasal syndrome completed the Frontal Systems Behavior Scale (FrSBe) and the Zarit Burden Interview (ZBI). To analyze the association between apathy or disinhibition (or both) and caregiver burden, the effects of the total FrSBe and the apathy and disinhibition subscales of the FrSBE on the total ZBI score were assessed with logistic regressions and t tests. Results Total FrSBE score and the apathy FrSBE subscore predicted caregiver burden. Apathy occurred without disinhibition, and the two occurred together, but disinhibition without apathy was very rare. Conclusions Disinhibition without apathy occurred very rarely. Apathy was more associated with caregiver burden than disinhibition. PMID:24022248

To quantify the magnitude of functional recovery in older adults with and without dementia admitted to an inpatient geriatric rehabilitation program by measuring change in measures of global physical function and physical therapy treatment outcomes. Retrospective cohort study. Rehabilitation academic hospital. Consecutive subjects, with (N=65, age 81.9±6.0 y) and without (N=157, age 82.8±7.2 y) a dementia diagnosis, had assessment data at admission and discharge from inpatient geriatric rehabilitation unit. Not applicable. The Functional Independence Measure (FIM) was used to estimate level of independence on activities of daily living. The Berg Balance Scale (BBS), Timed Up and Go Test (TUG) and 2 Minute Walk Test (2MWT) were used to estimate functional mobility and endurance. The FIM (total, motor subscale, cognitive subscale scores) were used to calculate rehabilitation efficacy and efficiency scores. After controlling for confounding, there was no group difference for gains on the BBS, TUG, 2MWT; there was no group difference on rehabilitation efficacy and efficiency values based on the FIM motor subscale. The magnitude of the rehabilitation gain using the total FIM score was statistically different between groups, people with dementia having smaller gains. Older adults with a diagnosis of dementia are capable of making motor function recovery during inpatient sub-acute rehabilitation comparable to their peers without a dementia diagnosis. The metric used to evaluate functional recovery influences the determination of rehabilitation success between groups. Rehabilitation success should be defined among people with a dementia diagnosis by a change in the motor subscale of the FIM, rather than the total FIM score or the gain relative to the maximal FIM score.

The Migraine Disability Assessment (MIDAS) Questionnaire is a reliable and valid instrument for migraine-related disability. Such a tool is needed to quantify migraine-related disability in the Greek population. This validation study aims to assess the test-retest reliability, internal consistency, item discriminant and convergent validity of the Greek translation of the MIDAS. Adults diagnosed with migraine completed the MIDAS Questionnaire on two occasions 3 weeks apart to assess reliability, and completed the RAND-36 to assess validity. Participants (n = 152) had a median MIDAS score of 24 and mostly severe disability (58% were grade IV). The test-retest reliability analysis (N = 59) revealed excellent reliability for the total score. Internal consistency was α = 0.71 for initial and α = 0.82 for retest completion. For item discriminant validity, the correlations between each question and the total score were significant, with high correlations for questions 2-5 (range 0.67 ≤ r ≤ 0.79; p < 0.01). For convergent validity, there was significant negative correlation between the total score and all RAND-36 subscales except for 'emotional wellbeing'. The negative correlation indicates that patients with a lower degree of disability according to their MIDAS score tended to have better wellbeing. Psychometric properties are comparable with those of other published validation studies of the MIDAS and the original. Findings on question 1 show that missing work/school days may be closely related with increased affect issues. The Greek version of the MIDAS Questionnaire has good reliability and validity. This study allowed for cross-cultural comparability of research findings.

Purpose: To develop a telephone version of the Chedoke-McMaster Stroke Assessment Activity Inventory (CMSA-AI) and estimate the test-retest reliability, interrater reliability (between participant and proxy), and construct validity of the scores for individuals with stroke. Methods: Adults with stroke and their caregivers or proxies were included. Participants were assessed with the CMSA-AI at discharge from a stroke rehabilitation unit and interviewed using the telephone version (TCMSA-AI). Two months after discharge, participants were evaluated with the CMSA-AI and interviewed over the phone using the TCMSA-AI on two occasions 2-3 days apart. Proxies were interviewed with the TCMSA-AI within another 2-3 days. Results: The mean age of the 53 participants with stroke was 62 years; 59% were male; 43% had right-side hemiparesis; 42 completed follow-up interviews; and 18 had proxies who also participated. Test-retest reliability showed an intra-class correlation coefficient of 0.98 (95% CI: 0.96, 0.99) for the total score, 0.96 (95% CI: 0.91, 0.98) for the Gross Motor Function Index, and 0.96 (95% CI: 0.91, 0.98) for the Walking Index, and an interrater reliability (between participant and proxy) of 0.75 (95% CI: 0.28, 0.90) for total score. Spearman's rho correlation between CMSA-AI and TCMSA-AI total scores was 0.62 (lower-sided 95% CI: 0.42) at discharge and 0.90 (lower-sided 95% CI: 0.82) at 2 months after discharge. Correlations between the change scores of the CMSA-AI and TCMSA-AI were 0.50 or lower. Conclusion: There is potential for remote evaluation of the functional mobility of individuals with stroke in research and clinical settings.

Background : Computed tomography (CT) of the lungs is the gold standard for assessing the extent of structural changes in the lungs. Spirometry-controlled chest CT (SCCCT) has improved the usefulness of CT by standardising inspiratory and expiratory lung volumes during imaging. This was a single-centre cross-sectional study in children with cystic fibrosis (CF). Using SCCCT we wished to investigate the association between the quantity and extent of structural lung changes and pulmonary function outcomes, and prevalence of known CF lung pathogens. Methods : CT images were analysed by CF-CT scoring (expressed as % of maximum score) to quantify different aspects of structural lung changes including bronchiectasis, airway wall thickening, mucus plugging, opacities, cysts, bullae and gas trapping. Clinical markers consisted of outcomes from pulmonary function tests, microbiological cultures from sputum and serological samples reflecting anti-bacterial and anti-fungal antibodies. Results : Sixty-four children with CF, median age (range) of 12.7 (6.4-18.1) years, participated in the study. The median (range) CF-CT total score in all children was 9.3% (0.4-46.8) with gas trapping of 40.7% (3.7-100) as the most abundant finding. Significantly higher median CF-CT total scores (21.9%) were found in patients with chronic infections ( N  = 12) including Gram-negative infection and allergic bronchopulmonary aspergillosis (ABPA) exhibiting CF-CT total scores of 14.2% (ns) and 24.0% ( p  < 0.01), respectively, compared to 8.0% in patients with no chronic lung infection. Lung clearance index (LCI) derived from multiple breath washout exhibited closest association with total CF-CT scores, compared to other pulmonary function outcomes. Conclusions : The most prominent structural lung change was gas trapping, while CF-CT total scores were generally low, both showing close association with LCI. Chronic lung infections, specifically in the form of ABPA, were associated with increased scores in lung changes. Further investigation of impact of infections with different microorganisms on extent and progression of structural CF lung disease is needed.

Bladder symptoms such as urinary urgency, frequency, and incontinence are common in people with multiple sclerosis (MS). These symptoms, which often result from neurogenic detrusor overactivity (NDO), can have a major impact on patients' day-to-day lives. However, in many cases they are over-looked in the clinical management of MS. The objective of this study was to develop and validate a reliable, sensitive, and specific screening tool for patients with bladder problems related to MS. We performed a literature review and then conducted a content validation study followed by a multisite observational study of a new screening tool, the Actionable Bladder Symptom Screening Tool (ABSST). All ABSST domains as well as the total score met the threshold for good internal consistency (Cronbach α ≥ 0.70), with a Cronbach α value of 0.95 for the total score and values ranging from 0.85 to 0.90 for the three domains. The validity of the ABSST was demonstrated by high correlation of the domains and total score with the Overactive Bladder Questionnaire Short Form (OAB-q SF) Symptom Severity and Total Health-Related Quality of Life (HRQOL) scores (Spearman correlation coefficient ≥ 0.782). The predictive validity of the ABSST total score to identify patients who might receive a recommendation to see a urologist was strong. This new instrument, which was developed with input from clinicians as well as MS patients, meets the current content validity and psychometric testing thresholds established by the US Food and Drug Administration, with high sensitivity and specificity.

Diet quality or macronutrient composition of total daily sodium intake (dNa) <2300 mg/day in the United States (US) is unknown. Using data from 2011-2014 NHANES (National Health and Nutrition Examination Survey), we examined 24-h dietary recalls ( n = 10,142) from adults aged ≥18 years and investigated how diet composition and quality are associated with dNa. Diet quality was assessed using components of macronutrients and Healthy Eating Index 2010 (HEI-2010). Associations were tested using linear regression analysis adjusted for total energy (kcal), age, gender, and race/ethnicity. One-day dNa in the lower quartiles were more likely reported among women, older adults (≥65 years old), and lower quartiles of total energy (kcal) ( p -values ≤ 0.001). With increasing dNa, there was an increase in the mean protein, fiber, and total fat densities, while total carbohydrates densities decreased. As dNa increased, meat protein, refined grains, dairy, and total vegetables, greens and beans densities increased; while total fruit and whole fruit densities decreased. Modified HEI-2010 total score (total score without sodium component) increased as dNa increased (adjusted coefficient: 0.11, 95% confidence interval = 0.07, 0.15). Although diet quality, based on modified HEI-2010 total score, increased on days with greater dNa, there is much room for improvement with mean diet quality of about half of the optimal level.

To evaluate an external quality assessment (EQA) program for human immunodeficiency virus (HIV) rapid diagnostics testing by the Haitian National Public Health Laboratory (French acronym: LNSP). Acceptable performance was defined as any proficiency testing (PT) score more than 80%. The PT database was reviewed and analyzed to assess the testing performance of the participating laboratories and the impact of the program over time. A total of 242 laboratories participated in the EQA program from 2006 through 2011; participation increased from 70 laboratories in 2006 to 159 in 2011. In 2006, 49 (70%) laboratories had a PT score of 80% or above; by 2011, 145 (97.5%) laboratories were proficient (P < .05). The EQA program for HIV testing ensures quality of testing and allowed the LNSP to document improvements in the quality of HIV rapid testing over time.

Construct: Valid score interpretation is important for constructs in performance assessments such as objective structured clinical examinations (OSCEs). An OSCE is a type of performance assessment in which a series of standardized patients interact with the student or candidate who is scored by either the standardized patient or a physician examiner. In high-stakes examinations, test security is an important issue. Students accessing unauthorized test materials can create an unfair advantage and lead to examination scores that do not reflect students' true ability level. The purpose of this study was to assess the impact of various simulated security breaches on OSCE scores. Seventy-six 3rd-year medical students participated in an 8-station OSCE and were randomized to either a control group or to 1 of 2 experimental conditions simulating test security breaches: station topic (i.e., providing a list of station topics prior to the examination) or egregious security breach (i.e., providing detailed content information prior to the examination). Overall total scores were compared for the 3 groups using both a one-way between-subjects analysis of variance and a repeated measure analysis of variance to compare the checklist, rating scales, and oral question subscores across the three conditions. Overall total scores were highest for the egregious security breach condition (81.8%), followed by the station topic condition (73.6%), and they were lowest for the control group (67.4%). This trend was also found with checklist subscores only (79.1%, 64.9%, and 60.3%, respectively for the security breach, station topic, and control conditions). Rating scale subscores were higher for both the station topic and egregious security breach conditions compared to the control group (82.6%, 83.1%, and 77.6%, respectively). Oral question subscores were significantly higher for the egregious security breach condition (88.8%) followed by the station topic condition (64.3%), and they were the lowest for the control group (48.6%). This simulation of different OSCE security breaches demonstrated that student performance is greatly advantaged by having prior access to test materials. This has important implications for medical educators as they develop policies and procedures regarding the safeguarding and reuse of test content.

Measurement of ability emotional intelligence: results for two new tests.

PubMed

Austin, Elizabeth J

2010-08-01

Emotional intelligence (EI) has attracted considerable interest amongst both individual differences researchers and those in other areas of psychology who are interested in how EI relates to criteria such as well-being and career success. Both trait (self-report) and ability EI measures have been developed; the focus of this paper is on ability EI. The associations of two new ability EI tests with psychometric intelligence, emotion perception, and the Mayer-Salovey-Caruso EI test (MSCEIT) were examined. The new EI tests were the Situational Test of Emotion Management (STEM) and the Situational Test of Emotional Understanding (STEU). Only the STEU and the MSCEIT Understanding Emotions branch were significantly correlated with psychometric intelligence, suggesting that only understanding emotions can be regarded as a candidate new intelligence component. These understanding emotions tests were also positively correlated with emotion perception tests, and STEM and STEU scores were positively correlated with MSCEIT total score and most branch scores. Neither the STEM nor the STEU were significantly correlated with trait EI tests, confirming the distinctness of trait and ability EI. Taking the present results as a starting-point, approaches to the development of new ability EI tests and models of EI are suggested.

Immunohistochemistry (IHC) is used as the frontline assay to determine HER2 status in invasive breast cancer patients. The aim of the study was to compare the performance of the Leica Oracle HER2 Bond IHC System (Oracle) with the current most readily accepted Dako HercepTest (HercepTest), using both commercially validated and modified ASCO/CAP and UK HER2 IHC scoring guidelines. A total of 445 breast cancer samples from 3 international clinical HER2 referral centers were stained with the 2 test systems and scored in a blinded fashion by experienced pathologists. The overall agreement between the 2 tests in a 3×3 (negative, equivocal and positive) analysis shows a concordance of 86.7% and 86.3%, respectively when analyzed using commercially validated and modified ASCO/CAP and UK HER2 IHC scoring guidelines. There is a good concordance between the Oracle and the HercepTest. The advantages of a complete fully automated test such as the Oracle include standardization of key analytical factors and improved turn around time. The implementation of the modified ASCO/CAP and UK HER2 IHC scoring guidelines has minimal effect on either assay interpretation, showing that Oracle can be used as a methodology for accurately determining HER2 IHC status in formalin fixed, paraffin-embedded breast cancer tissue.

The CaPTHUS model was reported to have a positive predictive value of 100 % to correctly predict single-gland disease in patients with primary hyperparathyroidism, thus obviating the need for intraoperative parathyroid hormone (ioPTH) testing. We sought to apply the CaPTHUS scoring model in our patient population and assess its utility in predicting long-term biochemical cure. We retrospective reviewed all parathyroidectomies for primary hyperparathyroidism performed at our university hospital from 2003 to 2012. We routinely perform ioPTH testing. Biochemical cure was defined as a normal calcium level at 6 months. A total of 1,421 patients met the inclusion criteria: 78 % of patients had a single adenoma at the time of surgery, 98 % had a normal serum calcium at 1 week postoperatively, and 96 % had a normal serum calcium level 6 months postoperatively. Using the CaPTHUS scoring model, 307 patients (22.5 %) had a score of ≥ 3, with a positive predictive value of 91 % for single adenoma. A CaPTHUS score of ≥ 3 had a positive predictive value of 98 % for biochemical cure at 1 week as well as at 6 months. In our population, where ioPTH testing is used routinely to guide use of bilateral exploration, patients with a preoperative CaPTHUS score of ≥ 3 had good long-term biochemical cure rates. However, the model only predicted adenoma in 91 % of cases. If minimally invasive parathyroidectomy without ioPTH testing had been done for these patients, the cure rate would have dropped from 98 % to an unacceptable 89 %. Even in these patients with high CaPTHUS scores, multigland disease is present in almost 10 %, and ioPTH testing is necessary.

A new version of The Knee Society Knee Scoring System(©) (KSS) has recently been developed. Before this scale can be used in non-English-speaking populations, it has to be translated and validated for a particular population. We evaluated the construct and content validity, the test-retest reliability, and the internal consistency of the Dutch version of the New Knee Society KSS. A Dutch translation was performed using a forward-backward translation protocol. We tested the construct validity of the Dutch New KSS by comparing it with the Dutch versions of the WOMAC, Knee Injury and Osteoarthritis Outcome Score (KOOS), and SF-12 scores in 137 patients undergoing total knee arthroplasty (TKA). Content validity was assessed by comparing pre- and postoperative scores and by checking floor and ceiling effects. To evaluate test-retest reliability and consistency, 47 patients completed the questionnaire a second time with a mean of 8 days interval (range, 2-20 days) between tests. Construct validity was demonstrated because the Dutch New KSS correlated well with the Dutch WOMAC (r = -0.751; p < 0.001), Dutch KOOS (r = -0.723; p < 0.001), and Dutch SF-12 (r = 0.569; p < 0.001). There was a significant difference between pre- and postoperative scores (p < 0.001) in line with the other scores. Test-retest reliability proved excellent with an intraclass correlation coefficient between 0.73 and 0.92 depending on the domain tested. Consistency as indicated by Cronbach's alpha ranging from 0.84 to 0.96 was good to excellent. As demonstrated by the validation procedure, the Dutch New KSS is an excellent instrument to evaluate TKA outcome in Dutch-speaking patients.

Videoconferencing has been used to expand medical services to low-access populations and could increase access to genetic services at community sites where in-person visits with genetic providers are not available. To evaluate the feasibility of, patient feedback of, and cognitive and affective responses to remote two-way videoconferencing (RVC) telegenetic services at multiple sociodemographically diverse community practices without access to genetic providers. Patients at 3 community sites in 2 US states outside the host center completed RVC pretest (visit 1, V1) and post-test (visit 2, V2) genetic counseling for cancer susceptibility. Surveys evaluated patient experiences, knowledge, satisfaction with telegenetic and cancer genetics services, anxiety, depression, and cancer worry. A total of 82 out of 100 (82.0%) approached patients consented to RVC services. A total of 61 out of 82 patients (74%) completed pretest counseling and 41 out of 61 (67%) proceeded with testing and post-test counseling. A total of 4 out of 41 (10%) mutation carriers were identified: BRCA2, MSH2, and PMS2. Patients reported many advantages (eg, lower travel burden and convenience) and few disadvantages to RVC telegenetic services. Most patients reported feeling comfortable with the video camera--post-V1: 52/57 (91%); post-V2: 39/41 (95%)--and that their privacy was respected--post-V1: 56/57 (98%); post-V2: 40/41 (98%); however, some reported concerns that RVC might increase the risk of a confidentiality breach of their health information--post-V1: 14/57 (25%); post-V2: 12/41 (29%). While the majority of patients reported having no trouble seeing or hearing the genetic counselor--post-V1: 47/57 (82%); post-V2: 39/41 (95%)--51 out of 98 (52%) patients reported technical difficulties. Nonetheless, all patients reported being satisfied with genetic services. Compared to baseline, knowledge increased significantly after pretest counseling (+1.11 mean score, P=.005); satisfaction with telegenetic (+1.74 mean score, P=.02) and genetic services (+2.22 mean score, P=.001) increased after post-test counseling. General anxiety and depression decreased after pretest (-0.97 mean anxiety score, P=.003; -0.37 mean depression score, P=.046) and post-test counseling (-1.13 mean anxiety score, P=.003; -0.75 mean depression score, P=.01); state anxiety and cancer-specific worry did not significantly increase. Remote videoconferencing telegenetic services are feasible, identify genetic carriers in community practices, and are associated with high patient satisfaction and favorable cognitive and affective outcomes, suggesting an innovative delivery model for further study to improve access to genetic providers and services. Potential barriers to dissemination include technology costs, unclear billing and reimbursement, and state requirements for provider licensure.

Cervical cancer is a serious public health problem in South Africa. Even though the screening is free in health facilities in South Africa, the Pap smear uptake is very low. The objective of the study is to investigate the knowledge and beliefs of female university students in South Africa. A cross sectional study was conducted among university women in South Africa to elicit information about knowledge and beliefs, and screening history. A total of 440 students completed the questionnaire. The average age of the participants was 20.39 years (SD  = 1.71 years). Regarding cervical cancer, 55.2% (n = 243) had ever heard about it. Results indicated that only 15% (22/147) of the students who had ever had sex and had heard about cervical cancer had taken a Pap test. Pearson correlation analysis showed that cervical cancer knowledge had a significantly negative relationship with barriers to cervical cancer screening. Susceptibility and seriousness score were significantly moderately correlated with benefit and motivation score as well as barrier score. Self-efficacy score also had a moderate correlation with benefit and motivation score. Students who had had a Pap test showed a significantly lower score in barriers to being screened compared to students who had not had a Pap test. This study showed that educated women in South Africa lack complete information on cervical cancer. Students who had had a Pap test had significantly lower barriers to cervical cancer screening than those students who had not had a Pap test.

Acquired brain injury (ABI) often leads to deficits in executive functioning (EF) responsible for severe and long-standing disabilities in daily life activities. The Cooking Task is an ecological and valid test of EF involving multi-tasking in a real environment. Given its complex scoring system, it is important to establish the tool's reliability. The objective of the study was to examine the reliability of the Cooking Task (internal consistency, inter-rater and test-retest reliability). A total of 160 patients with ABI (113 men, mean age 37 years, SD = 14.3) were tested using the Cooking Task. For test-retest reliability, patients were assessed by the same rater on two occasions (mean interval 11 days) while two raters independently and simultaneously observed and scored patients' performances to estimate inter-rater reliability. Internal consistency was high for the global scale (Cronbach α = .74). Inter-rater reliability (n = 66) for total errors was also high (ICC = .93), however the test-retest reliability (n = 11) was poor (ICC = .36). In general the Cooking Task appears to be a reliable tool. The low test-retest results were expected given the importance of EF in the performance of novel tasks.

Symptoms of anxiety and depression are related to cardiovascular responses to active, but not passive, coping tasks.

Anxiety and depression have been linked to blunted blood pressure (BP) and heart rate (HR) reactions to mental stress tests; however, most studies have not included indices of underlying hemodynamics nor multiple stress tasks. This study sought to examine the relationships of anxiety and depression with hemodynamic responses to acute active and passive coping tasks. A total of 104 participants completed the Hospital Anxiety and Depression Scales and mental arithmetic, speech, and cold pressor tasks while BP, HR, total peripheral resistance, and cardiac output (CO) were assessed. After adjustment for traditional risk factors and baseline cardiovascular activity, depression scores were negatively associated with systolic BP, HR, and CO responses to the mental arithmetic task, while anxiety scores were inversely related to the systolic BP response to mental arithmetic. High anxiety or depression scores appear to be associated with blunted cardiac reactions to mental arithmetic (an active coping task), but not to the cold pressor test or speech tasks. Future research should further examine potential mechanisms and longitudinal pathways relating depression and anxiety to cardiovascular reactivity. TCTR20160208004.

To compare baseline scores of middle and high school students on the Sport Concussion Assessment Tool 2 (SCAT2) by sex and age. Cross-sectional study. Single private school athletic program. Three hundred sixty-one middle and high school student-athletes. Preseason SCAT2 was administered to student-athletes before athletic participation. Total SCAT2 score, symptoms, symptom severity, Glasgow coma scale, modified Balance Error Scoring System (BESS), coordination, and Standardized Assessment of Concussion (SAC) with subsections: Orientation, Immediate Memory, Concentration, and Delayed Recall. No differences were found in total SCAT2 scores between sex (P = 0.463) or age (P = 0.21). Differences were found in subcomponents of the SCAT2. Twelve year olds had significantly lower concentration scores (3.3 ± 1.2) than 15 and 18 year olds (3.9 ± 1.0 and 4.2 ± 1.0, respectively). The 12 year olds also had the lowest percentage of correct responses for the SAC's concentration 5-digit (46%), 6-digit (21%), and months' backward (67%) tasks. Females presented with more symptoms (20.0 ± 2.2 vs. 20.6 ± 2.1 P = 0.007) better immediate memory (14.6 ± 0.9 vs. 14.3 ± 1.0, P = 0.022) and better BESS scores (27.2 ± 2.3 vs. 26.6 ± 2.6, P = 0.043) than their male counterparts. Normative values for total SCAT2 and subscale scores show differences in concentration between ages, whereas symptoms, BESS, and immediate memory differed between sexes. We also found that 12 year olds have increased difficultly with the advanced concentration tasks, which lends support to the development of a separate instrument, such as the Child-SCAT3. The presence of developmental differences in the younger age groups suggests the need for annual baseline testing. Subtle differences between age and sex have been identified in many components of the SCAT2 assessment. These differences may support the current evolution of concussion assessment tools to provide the most appropriate test. Baseline testing should be used when available, and clinicians should be aware of potential differences when using normalized values.

Extreme prematurity or extremely low birth weight (ELBW) can adversely affect behaviour. Nondisabled ELBW children are at risk of behavioural problems, which may become a particular concern after commencement of formal education. This study explored the frequency of behavioural and emotional problems amongst nondisabled ELBW children at 4 to 5 years of age and whether intervention had a positive influence on behaviour. The relationship between behaviour, gender, and other areas of performance at 5 years was explored. Fifty 4-year-old children (born <28 weeks gestation or birth weight <1,000 g) with minimal/mild motor impairment were randomly allocated to intervention (n = 24) or standard care (n = 26). Intervention was 6 group-based physiotherapy weekly sessions and home programme. Standard care was best practice advice. The Child Behavior Checklist (CBCL) for preschool children was completed at baseline and at 1-year post-baseline. Other measures at follow-up included Movement Assessment Battery for Children Second Edition, Beery Visual-Motor Integration Test 5th Edition, and Peabody Picture Vocabulary Test 4th Edition. The whole cohort improved on CBCL total problems score between baseline (mean 50.0, SD 11.1) and 1-year follow-up (mean 45.2, SD 10.3), p = .004. There were no significant differences between groups over time on CBCL internalizing, externalizing, or total problems scores. The intervention group showed a mean difference in total problems score of -3.8 (CI [1.5, 9.1]) between times, with standard care group values being -4.4 (CI [1.6, 7.1]). Males had higher total problems scores than females (p = .026), although still performed within the "normal" range. CBCL scores did not correlate with other scores. The behaviour of nondisabled ELBW children was within the "normal" range at 4 to 5 years, and both intervention and standard care may have contributed to improved behavioural outcomes. Behaviour was not related to performance in other developmental domains. © 2017 John Wiley & Sons Ltd.

The currently approved objective clinical measure of standing balance in astronauts after space flight is the Sensory Organization Test battery of computerized dynamic posturography. No tests of walking balance are currently approved for standard clinical testing of astronauts. This study determined the sensitivity and specificity of standing and walking balance tests for astronauts before and after long-duration space flight. Astronauts were tested on an obstacle avoidance test known as the Functional Mobility Test (FMT) and on the Sensory Organization Test using sway-referenced support surface motion with eyes closed (SOT 5) before and six months after (n=15) space flight on the International Space Station. They were tested two to seven days after landing. Scores on SOT tests decreased and scores on FMT increased significantly from pre- to post-flight. In other words, post-flight scores were worse than pre-flight scores. SOT and FMT scores were not significantly related. ROC analyses indicated supra-clinical cut-points for SOT 5 and for FMT. The standard clinical cut-point for SOT 5 had low sensitivity to post-flight astronauts. Higher cut-points increased sensitivity to post-flight astronauts but decreased specificity to pre-flight astronauts. Using an FMT cut-point that was moderately highly sensitive and highly specific plus SOT 5 at the standard clinical cut-point was no more sensitive than SOT 5, alone. FMT plus SOT 5 at higher cut-points was more specific and more sensitive. The total correctly classified was highest for FMT, alone, and for FMT plus SOT 5 at the highest cut-point. These findings indicate that standard clinical comparisons are not useful for identifying problems. Testing both standing and walking balance will be more likely to identify balance deficits.

Pain alleviation and improvement of functional status are the main objectives in the treatment of osteoarthritis. Artemisia absinthium (AA) was used traditionally in reducing pain and inflammation. The aim of the present study was to compare the effects of topical formulations of AA and piroxicam gel (PG) among patients with knee osteoarthritis. In total, 90 outpatients aged 30-70 years with the diagnosis of primary osteoarthritis in at least one knee were enrolled in a randomized double-blind clinical trial. The patients referred to the Rheumatology Clinic at Shahid Beheshti Hospital in Hamadan province during 2012-2013. The patients were randomly assigned into three groups, 30 patients per group, and respectively received AA ointment (AAO) 3%, AA liniment (AAL) 3%, and PG; three times daily (TID) for 4 weeks. The patients were visited at baseline, week 4, and week 6. The effectiveness criteria were pain severity which was assessed with a 10-point visual analog scale (VAS), the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) for total pain score (WTPS), total physical function score (WTPFS), and total stiffness score (WTSS). Repeated measure ANOVA, paired t test and post hoc were used to compare variables. Statistical analysis was performed using the SPSS software, version 13.0 (SPSS Inc., Chicago, Illinois). All groups had similar patient demographics. The administration of PG significantly improved all tested criteria with no recurrence after discontinuing the treatment protocol. AAO alleviated all tested factors except for WTSS. Alleviation was comparable to PG. AAL only reduced pain factors (VAS, WTPS) in week 4 with recurrence in week 6. Administration of Artemisia ointment may have beneficial effects in the treatment of osteoarthritis. Trial Registration Number: IRCT201202123109N3.

This study aimed to investigate the effect of trospium chloride on cognitive function in postmenopausal women treated for overactive bladder (OAB). Randomized double-blind placebo-controlled trial conducted from April 2013 to April 2015. Women aged 50 years or older seeking treatment for OAB were randomized to either trospium chloride XR 60 mg daily or placebo. Baseline cognitive function was assessed via Hopkins Verbal Learning Test-Revised (HVLT-R), Mini Mental Status Exam, Mini Mental Status X, Digit Span, Trails A, Trails B, and Epworth Sleepiness Scale. Cognitive function was reassessed at week 1 and week 4. A priori power analysis determined that 21 subjects were needed per group. Although 59 women were enrolled and randomized (28 trospium and 31 placebo), 45 completed assessment (21 trospium and 24 placebo). Mean age was 68 years, 78% were white, and 44% had previously taken OAB medication. For the primary outcome, there was no difference in HVLT-R total score between trospium and placebo groups at week 4 (P = 0.29). There were also no differences based on the other cognitive tests. There was a correlation between age and the following week-4 tests: HVLT-R total score (r = -0.3, P = 0.02), HVLT-R total recall subscale (r = -0.4, P = 0.007), Trails A (r = 0.4, P = 0.002), and Trails B (r = 0.4, P = 0.004). A linear regression model found that HVLT-R total score decreased by 0.372 points for each increased year of age. In women aged 50 years and older, there were no changes in cognitive function between those taking trospium and placebo. Cognitive function was correlated with age.

Context: Although evidence-based practice (EBP) has become more prevalent, athletic trainers' perceptions of importance and knowledge of these concepts and their confidence in EBP are largely unknown. Objective: To assess perceived importance and knowledge of and confidence in EBP concepts in athletic trainers in various roles and with different degree levels. Design: Cross-sectional study. Setting: Online survey instrument. Patients or Other Participants: The survey was sent to 6702 athletic training educators, clinicians, and postprofessional students. A total of 1209 completed the survey, for a response rate of 18.04%. Main Outcome Measure(s): Demographic information and perceived importance and knowledge of and confidence in the steps of EBP were obtained. One-way analysis of variance, a Kruskal-Wallis test, and an independent-samples t test were used to determine differences in scores among the demographic variables. Results: Athletic trainers demonstrated low knowledge scores (64.2% ± 1.29%) and mild to moderate confidence (2.71 ± 0.55 out of 4.0). They valued EBP as moderately to extremely important (3.49 ± 0.41 out of 4.0). Perceived importance scores differed among roles (clinicians unaffiliated with an education program scored lower than postprofessional educators, P = .001) and highest educational degree attained (athletic trainers with terminal degrees scored higher than those with bachelor's or master's degrees, P < .001). Postprofessional athletic training students demonstrated the highest total EBP knowledge scores (4.65 ± 0.91), whereas clinicians demonstrated the lowest scores (3.62 ± 1.35). Individuals with terminal degrees had higher (P < .001) total knowledge scores (4.31 ± 1.24) than those with bachelor's (3.78 ± 1.2) or master's degrees (3.76 ± 1.35). Postprofessional educators demonstrated greater confidence in knowledge scores (3.36 ± 0.40 out of 4.0) than did those in all other athletic training roles (P < .001). Conclusions: Overall knowledge of the basic EBP steps remained low across the various athletic trainers' roles. The higher level of importance indicated that athletic trainers valued EBP, but this value was not reflected in the knowledge of EBP concepts. Individuals with a terminal degree possessed higher knowledge scores than those with other educational preparations; however, EBP knowledge needs to increase across all demographics of the profession.

The accuracy of Internet search engines to predict diagnoses from symptoms can be assessed with a validated scoring system.

Shenker, Bennett S

2014-02-01

To validate a scoring system that evaluates the ability of Internet search engines to correctly predict diagnoses when symptoms are used as search terms. We developed a five point scoring system to evaluate the diagnostic accuracy of Internet search engines. We identified twenty diagnoses common to a primary care setting to validate the scoring system. One investigator entered the symptoms for each diagnosis into three Internet search engines (Google, Bing, and Ask) and saved the first five webpages from each search. Other investigators reviewed the webpages and assigned a diagnostic accuracy score. They rescored a random sample of webpages two weeks later. To validate the five point scoring system, we calculated convergent validity and test-retest reliability using Kendall's W and Spearman's rho, respectively. We used the Kruskal-Wallis test to look for differences in accuracy scores for the three Internet search engines. A total of 600 webpages were reviewed. Kendall's W for the raters was 0.71 (p<0.0001). Spearman's rho for test-retest reliability was 0.72 (p<0.0001). There was no difference in scores based on Internet search engine. We found a significant difference in scores based on the webpage's order on the Internet search engine webpage (p=0.007). Pairwise comparisons revealed higher scores in the first webpages vs. the fourth (corr p=0.009) and fifth (corr p=0.017). However, this significance was lost when creating composite scores. The five point scoring system to assess diagnostic accuracy of Internet search engines is a valid and reliable instrument. The scoring system may be used in future Internet research.

Analysis of inter-rater reliability and concurrent validity. To determine measurement properties of a Spanish version of The Coma Recovery Scale-Revised (CRS-R). A sample of 35 in-patients with severe acquired brain injury. To test concurrent validity of the translated scale, the Glasgow Coma Scale (GSC) and Disability Rating Scale (DRS) were also administered. Two experts in the field were recruited to assess inter-rater agreement. Inter-rater reliability was good for total CRS-R scores (Cronbach α = 0.973, p = 0.001). Sub-scale analysis showed moderate-to-high inter-rater agreement. Total CRS-R scores correlated significantly (p < 0.05) with total GCS (r = 0.74) and DRS (r = 0.54) scores, indicating acceptable concurrent validity. The Spanish version of CRS-R can be administered reliably by trained and experienced examiners. CRS-R appears capable of differentiating patients in Emergence from Minimally Conscious State (EMCS) or in Minimally Conscious State (MCS) from those in a Vegetative State (VS).

Questionnaires addressing auditory disability may identify and quantify specific symptoms in adult patients with listening difficulties. (1) To assess validity of the Speech, Spatial, and Qualities of Hearing Scale (SSQ), the (Modified) Amsterdam Inventory for Auditory Disability (mAIAD), and the Hyperacusis Questionnaire (HYP) in adult patients experiencing listening difficulties in the presence of a normal audiogram. (2) To examine which individual questionnaire items give the worse scores in clinical participants with an auditory processing disorder (APD). A prospective correlational analysis study. Clinical participants (N = 58) referred for assessment because of listening difficulties in the presence of normal audiometric thresholds to audiology/ear, nose, and throat or audiovestibular medicine clinics. Normal control participants (N = 30). The mAIAD, HYP, and the SSQ were administered to a clinical population of nonneurological adults who were referred for auditory processing (AP) assessment because of hearing complaints, in the presence of normal audiogram and cochlear function, and to a sample of age-matched normal-hearing controls, before the AP testing. Clinical participants with abnormal results in at least one ear and in at least two tests of AP (and at least one of these tests to be nonspeech) were classified as clinical APD (N = 39), and the remaining (16 of whom had a single test abnormality) as clinical non-APD (N = 19). The SSQ correlated strongly with the mAIAD and the HYP, and correlation was similar within the clinical group and the normal controls. All questionnaire total scores and subscores (except sound distinction of mAIAD) were significantly worse in the clinical APD versus the normal group, while questionnaire total scores and most subscores indicated greater listening difficulties for the clinical non-APD versus the normal subgroups. Overall, the clinical non-APD group tended to give better scores than the APD in all questionnaires administered. Correlation was strong for the worse-ear gaps-in-noise threshold with the SSQ, mAIAD, and HYP; strong to moderate for the speech in babble and left-ear dichotic digit test scores (at p < 0.01); and weak to moderate for the remaining AP tests except the frequency pattern test that did not correlate. The worse-scored items in all three questionnaires concerned speech-in-noise questions. This is similar to worse-scored items by hearing-impaired participants as reported in the literature. Worse-scored items of the clinical group also included quality aspects of listening questions from the SSQ, which most likely pertain to cognitive aspects of listening, such as ability to ignore other sounds and listening effort. Hearing questionnaires may help assess symptoms of adults with APD. The listening difficulties and needs of adults with APD to some extent overlap with those of hearing-impaired listeners, but there are significant differences. The correlation of the gaps-in-noise and duration pattern (but not frequency pattern) tests with the questionnaire scores indicates that temporal processing deficits may play an important role in clinical presentation.

The Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 instrument (MDF-Fibro-17) has been developed for use in fibromyalgia (FM) clinical studies and includes 5 domains: Global Fatigue Experience, Cognitive Fatigue, Physical Fatigue, Motivation, and Impact on Function. Psychometric properties of the MDF-Fibro-17 needed to demonstrate the appropriateness of using this instrument in clinical studies are presented. Psychometric analyses were conducted to evaluate the factor structure, reliability, validity, and responsiveness of the MDF-Fibro-17 using data from a Phase 2 clinical study of FM patients (N = 381). Confirmatory factor analyses (CFA) were performed to ensure understanding of the multidimensional domain structure, and a secondary factor analysis of the domains examined the appropriateness of calculating a total score in addition to domain scores. Longitudinal psychometric analyses (test-retest reliability and responder analysis) were also conducted on the data from Baseline to Week 6. The CFA supported the 17-item, 5 domain structure of this instrument as the best fit of the data: comparative fit index (CFI) and non-normed fit index (NNFI) were 0.997 and 0.992 respectively, standardized root mean square residual (SRMR) was 0.010 and the root mean square error of approximation (RMSEA) was 0.06. In addition, total score (CFI and NNFI both 0.95) met required standards. For the total and 5 domain scores, reliability and validity data were acceptable: test-retest and internal consistency were above 0.9; correlations were as expected with the Global Fatigue Index (GFI) (0.62-0.75), Fibromyalgia Impact Questionnaire (FIQ) Total (0.59-0.71), and 36-Item Short Form Health Survey (SF-36) vitality (VT) (0.43-0.53); and discrimination was shown using quintile scores for the GFI, FIQ Total, and Pain Numeric Rating Scale (NRS) quartiles. In addition, sensitivity to change was demonstrated with an overall mean responder score of -2.59 using anchor-based methods. The MDF-Fibro-17 reliably measures 5 domains of FM-related fatigue and psychometric evaluation confirms that this measure meets or exceeds each of the predefined acceptable thresholds for evidence of reliability, validity, and responsiveness to changes in clinical status. This suggests that the MDF-Fibro-17 is an appropriate and responsive measure of FM-related fatigue in clinical studies.

Use of hydrocortisone to treat refractory haemodynamic instability in patients recovering from surgery for congenital heart disease is common practice at many centres. We aimed to determine whether there is a relationship between total serum cortisol concentrations and haemodynamic response to this therapy. Material and methods We retrospectively reviewed patients <21 years who underwent cardiac surgery from 2011 to 2013, received hydrocortisone within 72 hours postoperatively, and had total serum cortisol measurements contemporaneous with its administration. Favourable responders were defined as patients in whom, at 24 hours after hydrocortisone initiation, either (1) systolic blood pressure was increased or unchanged and vasoactive-inotrope score was decreased or (2) systolic blood pressure increased by ⩾10% of baseline and vasoactive-inotrope score was unchanged. Variables were compared using t-tests or Mann-Whitney U tests as appropriate. In total, 24 patients were reviewed, with a median age of 1.4 months and range of 0.1-232 months. Among them, 14 (58%) patients responded favourably to hydrocortisone. At 24 hours, the median change in vasoactive-inotrope score was -18% in favourable responders and +31% in those who did not respond favourably, p=0.001. The mean pre-hydrocortisone total serum cortisol in favourable responders was 17.4±10.9 µg/dl compared with 46.1±44.7 µg/dl in those who did not respond favourably, p=0.03. Total serum cortisol obtained before initiation of hydrocortisone was significantly lower in patients who responded favourably to this therapy. Total serum cortisol may therefore be helpful in identifying children recovering from cardiac surgery who may or may not haemodynamically improve with hydrocortisone.

To assess the validity and test-retest reliability of a Thai translation of the Migraine Disability Assessment (MIDAS) Questionnaire in Thai patients with migraine. Migraineurs from the Headache Clinic in Siriraj Hospital were recruited and asked to complete a 13-weeks diary and answered the Thai-MIDAS at once. Some participants were asked to provide the 2nd Thai-MIDAS in the next 2 weeks for test-retest reliability. Ninety-three patients had completed the 13-weeks diaries. Age range was 18-58 years with mean 37.69 +/- 9.60 years. All 5 items and the total score of Thai-MIDAS were moderately correlated with data from 13-weeks diary (Spearman's correlation coefficient = 0.32-0.62). The test-retest reliability of the total score of Thai-MIDAS in 30 patients demonstrated a highly reliable degree of intraclass correlation (ICC = 0.76, 95% CI 0.49-0.88). The present study reveals that the Thai-MIDAS has satisfactory validity and reliability in comparison with the original English MIDAS version.

The 20-m shuttle run test (MSRT) is a common field test used to measure aerobic fitness in controlled environments. The U.S. Army currently assesses aerobic fitness with the two-mile run (TMR), but external factors may impact test performance. The aim of this study is to examine the relationship between the Army Physical Fitness Test TMR performance and the MSRT in military personnel. A group of 531 (403 males and 128 females) active duty soldiers (age: 24.0 ± 4.1 years) performed the MSRT in an indoor facility. Heart rate was monitored for the duration of the test. Post-heart rate and age-predicted maximal heart rate were utilized to determine near-maximal performance on the MSRT. The soldiers provided their most recent Army Physical Fitness Test TMR time (min). A Pearson correlation and multiple linear regression analyses were performed to examine the relationship between TMR time (min) and MSRT score (total number of shuttles completed). The study was approved by the Human Use Review Committee at the U.S. Army Research Institute of Environmental Medicine, Natick, Massachusetts. A significant, negative correlation exists between TMR time and MSRT score (r = -0.75, p < 0.001). Sex and MSRT score significantly predicted TMR time (adjusted R2 = 0.65, standard error of estimate = 0.97, p < 0.001) with a 95% ratio limits of agreement of ±12.6%. The resulting equation is: TMR = 17.736-2.464 × (sex) - 0.050 × (MSRT) - 0.026 × (MSRT × sex) for predicted TMR time. Males equal zero, females equal one, and MSRT score is the total number of shuttles completed. The MSRT is a strong predictor of the TMR and should be considered as a diagnostic tool when assessing aerobic fitness in active duty soldiers.

Studies indicate a strong relationship between empathy and language skills, but the relationship between reading and empathy remains elusive, although a shared neural substrate (the temporoparietal junction; TPJ) has been implicated in both reading and empathy. Motivated by these observations, the purpose of the current study was to examine empathic skills in a large spectrum of reading abilities, including typical readers and individuals with dyslexia, and their relationship to reading competence. We administered the Intrapersonal Reactivity Index (IRI) test, which differentiates between two subscales of empathy (cognitive and emotional empathy), to a group of participants with dyslexia and typical readers. Results indicate that the general reading score (average z scores of all reading tests) was significantly positively correlated with empathic scores. In addition, tests of specific reading abilities-decoding, reading fluency, and reading-related measures of phonological awareness-were significantly positively correlated with empathic scores. Finally, participants with dyslexia who showed low reading abilities had significantly lower scores in total empathy and cognitive empathy, as measured by the IRI test, than did typical participants with high reading abilities. Taken together, these results indicate a strong association between reading-related skills and empathic abilities and may point to involvement of the TPJ in both empathy and reading.

Objectives: To investigate the effects of isokinetic exercise on pain and functional test scores of recreational athletes with chondromalacia patellae (CMP) and to examine the correlation between isokinetic parameters and functional tests or pain score. Methods: The functional ability of 30 recreational athletes with unilateral CMP was evaluated using six different tests. Pain scores were assessed during daily activities before and after the treatment protocol. Isokinetic exercise sessions were carried out at angular velocities of 60°/s (25–90° range of flexion) and 180°/s (full range). These sessions were repeated three times a week for six weeks. Results: Quadriceps and hamstring peak torque, total work, and endurance ratios had improved significantly after the treatment, as did the functional parameters and pain scores. There was a poor correlation between the extensor endurance ratio and one leg standing test. A moderate correlation between the visual analogue scale and the extensor endurance ratio or flexion endurance ratio was also found. Conclusions: The isokinetic exercise programme used in this study had a positive effect on muscle strength, pain score, and functional ability of knees with CMP. The improvement in the functional capacity did not correlate with the isokinetic parameters. PMID:14665581

Automatic systems for estimating operator fatigue have application in safety-critical environments. A system which could estimate level of fatigue from speech would have application in domains where operators engage in regular verbal communication as part of their duties. Previous studies on the prediction of fatigue from speech have been limited because of their reliance on subjective ratings and because they lack comparison to other methods for assessing fatigue. In this paper, we present an analysis of voice recordings and psychophysiological test scores collected from seven aerospace personnel during a training task in which they remained awake for 60 h. We show that voice features and test scores are affected by both the total time spent awake and the time position within each subject's circadian cycle. However, we show that time spent awake and time-of-day information are poor predictors of the test results, while voice features can give good predictions of the psychophysiological test scores and sleep latency. Mean absolute errors of prediction are possible within about 17.5% for sleep latency and 5-12% for test scores. We discuss the implications for the use of voice as a means to monitor the effects of fatigue on cognitive performance in practical applications.

We aimed to compare two digital nerve block techniques in patients due to traumatic digital lacerations. This was a randomized-controlled study designed prospectively in the emergency department of a university-based training and research hospital. Randomization was achieved by sealed envelopes. Half of the patients were randomised to traditional (two-injection) digital nerve block technique while single-injection digital nerve block technique was applied to the other half. Score of pain due to anesthetic infiltration and suturing, onset time of total anesthesia, need for an additional rescue injection were the parameters evaluated with both groups. Epinephrin added lidocaine hydrochloride preparation was used for the anesthetic application. Visual analog scale was used for the evaluation of pain scores. Outcomes were compared by using Mann-Whitney U test and Student t-test. Fifty emergency department patients ≥18 years requiring digital nerve block were enrolled in the study. Mean age of the patients was 33 (min-max: 19-86) and 39 (78 %) were male. No statistically significant difference was found between the two groups in terms of our main parameters; anesthesia pain score, suturing pain score, onset time of total anesthesia and rescue injection need. Single injection volar digital nerve block technique is a suitable alternative for digital anesthesias in emergency departments.

In a study to establish the interrater reliability of the Irish Nursing Minimum Data Set (I-NMDS) for mental health difficulties relating to the choice of reliability test statistic were encountered. The objective of this paper is to highlight the difficulties associated with testing interrater reliability for an ordinal scale using a relatively homogenous sample and the recommended kw statistic. One pair of mental health nurses completed the I-NMDS for mental health for a total of 30 clients attending a mental health day centre over a two-week period. Data was analysed using the kw and percentage agreement statistics. A total of 34 of the 38 I-NMDS for mental health variables with lower than acceptable levels of kw reliability scores achieved acceptable levels of reliability according to their percentage agreement scores. The study findings implied that, due to the homogeneity of the sample, low variability within the data resulted in the 'base rate problem' associated with the use of kw statistic. Conclusions point to the interpretation of kw in tandem with percentage agreement scores. Suggestions that kw scores were low due to chance agreement and that one should strive to use a study sample with known variability are queried.

Objective. To validate the Yoruba version of Family Burden Interview Schedule (Y-FBIS) for assessing the burden on caregivers of persons with schizophrenia. Methods. Three hundred and sixty-eight dyads of persons with schizophrenia and their caregivers were recruited from a psychiatric outpatient clinic. The (Y-FBIS) and the Yoruba version of the GHQ-12 (Y-GHQ-12) were applied to the caregivers. Patients' level of social functioning was assessed using the Global Assessment of Functioning scale. Results. All (368) caregivers were used for tests of internal consistency, 180 for interrater reliability, and another 180 for test-retest reliability. Internal consistency of the Y-FBIS was demonstrated by a significant Cronbach α of between 0.62 and 0.82 for each item. Concurrent validity of the Y-FBIS was illustrated by its significant positive correlation with Y-GHQ-12 (r = 0.633 , P < 0.01). Split-half reliability was 0.849. Intraclass correlation coefficient for the total score of Y-FBIS was 0.849 at 95% confidence interval. Test-retest reliability of individual scales ranged from 0.780 to 0.874 and was 0.830 for total objective scale score. Convergent validity was shown by the significant positive correlation (r = 0.83) between the objective burden score and subjective burden score of Y-FBIS. ROC curve area was 0.981. Conclusion. The Y-FBIS is a valid, reliable, and sensitive instrument for assessing the burden on caregivers of persons with schizophrenia in Nigeria. PMID:23738196

In this study, we aimed to develop two reliable and valid assessment instruments for investigating the level of difficulties mental health workers experience while working with patients with personality disorders and the attitudes they develop tt the patients. The research was carried out based on the general screening model. The study sample consisted of 332 mental health workers in several mental health clinics of Turkey, with a certain amount of experience in working with personality disorders, who were selected with a random assignment method. In order to collect data, the Personal Information Questionnaire, Difficulty of Working with Personality Disorders Scale (PD-DWS), and Attitudes Towards Patients with Personality Disorders Scale (PD-APS), which are being examined for reliability and validity, were applied. To determine construct validity, the Adjective Check List, Maslach Burnout Inventory, and State and Trait Anxiety Inventory were used. Explanatory factor analysis was used for investigating the structural validity, and Cronbach alpha, Spearman-Brown, Guttman Split-Half reliability analyses were utilized to examine the reliability. Also, item reliability and validity computations were carried out by investigating the corrected item-total correlations and discriminative indexes of the items in the scales. For the PD-DWS KMO test, the value was .946; also, a significant difference was found for the Bartlett sphericity test (p<.001). The computed test-retest coefficient reliability was .702; the Cronbach alpha value of the total test score was .952. For PD-APS KMO, the value was .925; a significant difference was found in Bartlett sphericity test (p<.001); the computed reliability coefficient based on continuity was .806; and the Cronbach alpha value of the total test score was .913. Analyses on both scales were based on total scores. It was found that PD-DWS and PD-APS have good psychometric properties, measuring the structure that is being investigated, are compatible with other scales, have high levels of internal reliability between their items, and are consistent across time. Therefore, it was concluded that both scales are valid and reliable instruments.

To facilitate large-scale assessment of a variety of cognitive abilities in clinical studies, we developed a self-administered online neuropsychological test battery: the Amsterdam Cognition Scan (ACS). The current studies evaluate in a group of adult cancer patients: test-retest reliability of the ACS and the influence of test setting (home or hospital), and the relationship between our online and a traditional test battery (concurrent validity). Test-retest reliability was studied in 96 cancer patients (57 female; M age  = 51.8 years) who completed the ACS twice. Intraclass correlation coefficients (ICCs) were used to assess consistency over time. The test setting was counterbalanced between home and hospital; influence on test performance was assessed by repeated measures analyses of variance. Concurrent validity was studied in 201 cancer patients (112 female; M age  = 53.5 years) who completed both the online and an equivalent traditional neuropsychological test battery. Spearman or Pearson correlations were used to assess consistency between online and traditional tests. ICCs of the online tests ranged from .29 to .76, with an ICC of .78 for the ACS total score. These correlations are generally comparable with the test-retest correlations of the traditional tests as reported in the literature. Correlating online and traditional test scores, we observed medium to large concurrent validity (r/ρ = .42 to .70; total score r = .78), except for a visuospatial memory test (ρ = .36). Correlations were affected-as expected-by design differences between online tests and their offline counterparts. Although development and optimization of the ACS is an ongoing process, and reliability can be optimized for several tests, our results indicate that it is a highly usable tool to obtain (online) measures of various cognitive abilities. The ACS is expected to facilitate efficient gathering of data on cognitive functioning in the near future.

To determine the relationship between maternal attachment, perceived social support and breast-feeding sufficiency. Descriptive correlational design. A state hospital and two family health centers in Sakarya, Turkey, between June to December 2011. The sample was 122 voluntary mothers who had healthy babies of 1 - 2 months old. The data were collected by a Personal Information Form, Maternal Attachment Inventory (MAI), Multidimensional Scale of Perceived Social Support (MSPSS) and Breast-feeding Self-Efficacy Scale-Short Form (BSES-SF). The data collected were analysed by percentage distribution, mean square, independent sample t-test, Mann-Whitney U, Kruskall-Wallis and Pearson correlation. The mean age of the mothers was 25.01 ± 2.2 years, and 48.4% of them were primary school graduates. BSESSF was 61.02 ± 8.44 (16 - 70), MAI was 99.07 ± 7.19 (56 - 100) and MSPSS was 66.40 ± 13.58 (37 - 84). There was a positive, medium level, significant relationship between the total scores of BSES-SF and MAI (r=0.370, p < 0.001). There was a positive, medium level, significant relationship between the total score of BSES-SF and the score from family subdimension of MSPSS (r=0.255, p < 0.01).There was a positive, medium level, significant relationship between the total score of MAI and the total score of family subdimension of MSPSS (r=0.339, p < 0.001). Successful maternal attachment and familial support positively affected the breast-feeding sufficiency of the mother.

Summary Background even if CrossFit training programs accounted actually more than 7500 gyms affiliated in the USA and more than 2000 in Europe and involved today more than 1 million of people, actually there were not several studies about the effect of the CrossFit on the health and sport performance. The aim of these research was to evaluate the performance in 7 fundamental movement patterns using a standardized methods, the Functional Movement Screen (FMS). Methods we enrolled three groups of athletes (age 17–40 years; >6 months of training programs): CrossFitters, body builders and professional weightlifters. FMS test was performed to all people enrolled. Scores of FMS test was examined comparing three groups. Results no differences in the three groups were showed in the mean score values of each test and in total score, except for shoulder mobility test (higher among CrossFitters) and trunk stability push-up test (higher among weightlifter). Agreement between the test performed on the two sides was higher in CrossFit groups for hurdle step (93.2%), in line lung (86%), rotary stability test (95.3%) and shoulder mobility (90.7%; p<0.001). Conclusions CrossFitters seem to have a high level of concordance in the scores achieved in bilateral test. CrossFit seems to produce marked symmetry in some fundamental movements compared to weightlifting and bodybuilding. PMID:27331045

2016-01-01

Finding the most appropriate intelligence test for adolescents with Intellectual Disability (ID) is challenging given their limited language, attention, perceptual, and motor skills and ability to stay on task. The study compared performance of 23 adolescents with ID on the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), one of the most widely used intelligence tests, and three non-verbal IQ tests, the Raven's Colored Progressive Matrices (RCPM), the Test of Non-verbal Intelligence-Fourth Edition and the Wechsler Non-verbal test of Ability. Results showed that the WISC-IV Full Scale IQ raw and scaled scores were highly correlated with total scores from the three non-verbal tests, although the correlations were higher for raw scores, suggesting they may lead to better understanding of within group differences and what individuals with ID can do at the time of assessment. All participants attempted more questions on the non-verbal tests than the verbal. A preliminary analysis showed that adolescents with ID without ASD (n = 15) achieved higher scores overall than those presenting with ID+ASD (n = 8). Our findings support the view that short non-verbal tests are more likely to give a similar IQ result as obtained from the WISC-IV. In terms of the time to administer and the stress for participants, they are more appropriate for assessing adolescents with ID. PMID:27242597

Finding the most appropriate intelligence test for adolescents with Intellectual Disability (ID) is challenging given their limited language, attention, perceptual, and motor skills and ability to stay on task. The study compared performance of 23 adolescents with ID on the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), one of the most widely used intelligence tests, and three non-verbal IQ tests, the Raven's Colored Progressive Matrices (RCPM), the Test of Non-verbal Intelligence-Fourth Edition and the Wechsler Non-verbal test of Ability. Results showed that the WISC-IV Full Scale IQ raw and scaled scores were highly correlated with total scores from the three non-verbal tests, although the correlations were higher for raw scores, suggesting they may lead to better understanding of within group differences and what individuals with ID can do at the time of assessment. All participants attempted more questions on the non-verbal tests than the verbal. A preliminary analysis showed that adolescents with ID without ASD (n = 15) achieved higher scores overall than those presenting with ID+ASD (n = 8). Our findings support the view that short non-verbal tests are more likely to give a similar IQ result as obtained from the WISC-IV. In terms of the time to administer and the stress for participants, they are more appropriate for assessing adolescents with ID.

Many patients with bulimia nervosa (BN) also meet criteria for a lifetime alcohol use disorder (AUD). In order to understand possible mechanisms contributing to the co-occurrence and perpetuation of these disorders, this study investigated the importance of impulsivity and test meal intake among patients with BN by comparing women with BN only (n = 18), BN and current/past AUDs (n = 13), and healthy controls (n = 12). All participants completed assessments of eating disorder symptoms, frequency of alcohol use, binge eating, and purging via questionnaires and semi-structured interviews over two sessions. Measures of impulsivity consisted of computerized and self-report measures, and laboratory test meals. Significant differences between individuals with BN with/without comorbid AUDs were not found for test meal intake, impulsivity measures, or self-reported psychological symptoms. As hypothesized, compared to healthy controls, individuals with BN had significantly higher scores on two subscales and the total score of the Barratt Impulsiveness Scale, a trait measure of impulsivity, and consumed significantly more calories in the binge instruction meal. Total Barratt Impulsiveness Scale scores were also significantly related to kcal consumed during the laboratory test meal when individuals were instructed to binge eat (BN groups). Data from this study add to the existing literature implicating impulsivity in the psychopathology of disorders of binge eating, including BN, and also support the use of laboratory meals as a symptom-specific measure of this trait in eating disorder populations.

The Yale-Brown Obsessive-Compulsive Scale for children and adolescents (CY-BOCS) is a frequently applied test to assess obsessive-compulsive symptoms. We conducted a reliability generalization meta-analysis on the CY-BOCS to estimate the average reliability, search for reliability moderators, and propose a predictive model that researchers and clinicians can use to estimate the expected reliability of the CY-BOCS scores. A total of 47 studies reporting a reliability coefficient with the data at hand were included in the meta-analysis. The results showed good reliability and a large variability associated to the standard deviation of total scores and sample size.

To determine whether changes occur over 1 academic year in pharmacy students' critical thinking skills and disposition to think critically. First, second, third, and fourth-year pharmacy students completed the California Critical Thinking Skills Test (CCTST) and the California Critical Thinking Disposition Inventory (CCTDI) at the beginning and end of 1 academic year. One hundred thirty-seven students completed the study. No significant changes occurred over the year in total scores on either instrument. However, scores in 3 of 12 subscale scores changed significantly and several significant correlations were found. Pharmacy students' scores on 2 critical thinking instruments showed no major improvements over 1 academic year but most scores were above average. Some areas of possible weakness were identified. Additional studies comparing scores over a longer period of time (eg, admission to graduation) are needed.

This study was designed to assess the test-retest reliability, internal consistency, and validity of a Japanese translation of the Migraine Disability Assessment (MIDAS) Questionnaire in a sample of Japanese patients with headache. Previous studies have demonstrated that the English-language version of the MIDAS Questionnaire is a reliable and valid instrument for the assessment of migraine-related disability. Any translations of the MIDAS Questionnaire must also be assessed for reliability and validity. Study participants were recruited from the patient population attending either the Neurology Department of Kitasato University or an affiliated clinic. Participants were eligible for study entry if they had 6 or more primary headaches per year. For reliability testing, participants completed the MIDAS Questionnaire on 2 occasions, exactly 2 weeks apart. To assess validity, patients were also invited to participate in a 90-day daily diary study. Composite measures from the 90-day diaries were compared to equivalent MIDAS measures (ie, 5 questions on headache-related disability and 1 question each on average pain intensity and headache frequency in the last 3 months) and to the total MIDAS score obtained from a third MIDAS Questionnaire completed at the end of this 90-day period. One hundred one patients between the ages of 21 and 77 years were recruited (81 women and 20 men). Ninety-nine patients (80 women and 19 men) participated in the diary study. At baseline, 46.5% of patients were MIDAS grade I or II (minimal, mild, or infrequent disability), 22.2% were MIDAS grade III (moderate disability), and 31.3% were MIDAS grade IV (severe disability). Test-retest Spearman correlations for the 5 disability questions and the questions on average pain intensity and headache frequency ranged from 0.59 to 0.80 (P<.0001). The test-retest Spearman correlation coefficient for the total MIDAS score was 0.83 (P<.0001). The degree to which individual MIDAS questions correlated with the diary-based measures ranged from 0.36 to 0.88. The correlation between the total MIDAS score and the equivalent diary-based measure was 0.66. In general, the mean and median values for the MIDAS items and total MIDAS score were similar to the means and medians for the diary-based measures. However, the mean MIDAS scores for the number of days on which headache was experienced and the number of missed workdays were significantly different compared to the diary-based estimates for these items (P<.05). In addition, the mean MIDAS score for the number of days of missed housework was significantly higher than the corresponding diary-based estimate (P<.01). The results from this study show that the Japanese translation of the MIDAS Questionnaire is comparable with the English-language version in terms of reliability and validity.

Concussions affect an estimated 136 000 high school athletes yearly. Computerized neurocognitive testing has been shown to be appropriately sensitive and specific in diagnosing concussions, but no studies have assessed its utility to predict length of recovery. Determining prognosis during subacute recovery after sports concussion will help clinicians more confidently address return-to-play and academic decisions. To quantify the prognostic ability of computerized neurocognitive testing in combination with symptoms during the subacute recovery phase from sports-related concussion. Cohort study (prognosis); Level of evidence, 2. In sum, 108 male high school football athletes completed a computer-based neurocognitive test battery within 2.23 days of injury and were followed until returned to play as set by international guidelines. Athletes were grouped into protracted recovery (>14 days; n = 50) or short-recovery (≤14 days; n = 58). Separate discriminant function analyses were performed using total symptom score on Post-Concussion Symptom Scale, symptom clusters (migraine, cognitive, sleep, neuropsychiatric), and Immediate Postconcussion Assessment and Cognitive Testing neurocognitive scores (verbal memory, visual memory, reaction time, processing speed). Multiple discriminant function analyses revealed that the combination of 4 symptom clusters and 4 neurocognitive composite scores had the highest sensitivity (65.22%), specificity (80.36%), positive predictive value (73.17%), and negative predictive value (73.80%) in predicting protracted recovery. Discriminant function analyses of total symptoms on the Post-Concussion Symptom Scale alone had a sensitivity of 40.81%; specificity, 79.31%; positive predictive value, 62.50%; and negative predictive value, 61.33%. The 4 symptom clusters alone discriminant function analyses had a sensitivity of 46.94%; specificity, 77.20%; positive predictive value, 63.90%; and negative predictive value, 62.86%. Discriminant function analyses of the 4 computerized neurocognitive scores alone had a sensitivity of 53.20%; specificity, 75.44%; positive predictive value, 64.10%; and negative predictive value, 66.15%. The use of computerized neurocognitive testing in conjunction with symptom clusters results improves sensitivity, specificity, positive predictive value, and negative predictive value of predicting protracted recovery compared with each used alone. There is also a net increase in sensitivity of 24.41% when using neurocognitive testing and symptom clusters together compared with using total symptoms on Post-Concussion Symptom Scale alone.

The purpose of this study was to describe outcome indicators of nursing education including critical thinking, professionalism, leadership, and communication and to evaluate differences among nursing programs and academic years. A descriptive research design was employed. A total of 454 students from four year baccalaureate (BS) nursing programs and two three-year associate degree (AD) programs consented to complete self-administered questionnaires. The variables were critical thinking, professionalism, leadership and communication. Descriptive statistics, χ2-test, t-tests, ANOVA, and the Tukey test were utilized for the data analysis. All the mean scores of the variables were above average for the test instruments utilized. Among the BS students, those in the upper classes tended to attain higher scores, but this tendency was not identified in AD students. There were significant differences between BS students and AD students for the mean scores of leadership and communication. These findings suggested the need for further research to define properties of nursing educational outcomes, and to develop standardized instruments for research replication and verification.

Given the forced-choice procedure of the identification test, patients with profound anosmia are more likely to have higher identification scores by chance than patients with hyposmia or normosmia. This may be a confusing factor when assessing the sense of smell, which alters the appreciation of real olfaction improvement. The aim of this study was to fine-tune the results of the identification Sniffin' Sticks test before and 6 weeks after surgery using the real identification score. A total of 133 patients underwent the Identification (I) and Threshold (T) tests the day before and 6 weeks after nasalization surgery. The scores of the identification test, called I G (global identification), were ranked from 0 to 16. Patients had to specify if their forced-choice answers were given either surely or randomly, called I H (hazard identification). The real score of identification I R was obtained as follow: I R  = I G  - I H . Patients with an immeasurable threshold according to the T test were more prone to give randomly correct answers. On the basis of I G scores, 43.6% of patients remained hypo-anosmic after surgery compared to 72.9% before surgery. Using I R scores, only 3.8% of patients remained anosmic (I R  = 0) at 6 weeks after surgery. Hence, patients with real anosmia (I R  = 0) were less prone to improve their olfaction than patients with I R  > 0. The analysis of random factor when using identification test allows differentiating a real anosmia from a hyposmia. An I G  ≤ 4 could be considered as a profound/real anosmia or a severe hyposmia. This procedure cannot, however, replace the forced-choice method in odor identification testing.
