Franken, Ingmar H A; Hendriksa, Vincent M; van den Brink, Wim

2002-01-01

In the present study, the factor structure, internal consistency, and the concurrent validity of two heroin craving questionnaires are examined. The Desires for Drug Questionnaire (DDQ) measures three factors: desire and intention, negative reinforcement, and control. The Obsessive Compulsive Drug Use Scale (OCDUS) also measures three factors: thoughts about heroin and interference, desire and control, and resistance to thoughts and intention. Subjects were 102 Dutch patients who were currently in treatment for drug dependency. All proposed scales have good reliability and concurrent validity. Implementation of these instruments in both clinical and research field is advocated.

The measurement of the social construct of Family Quality of Life (FQOL) is a parsimonious alternative to the current approach of measuring familial outcomes using a battery of tools related to individual-level outcomes. The purpose of this study was to examine the internal consistency and concurrent validity of the International FQOL Survey (FQOLS-2006), using cross-sectional data collected from 65 family caregivers of children with developmental disabilities. It shows a moderate correlation between the total FQOL scores of the FQOLS-2006 and the Beach Center's FQOL scale. The validity of five FQOLS-2006 domains was supported by the correlations between conceptually related domains.

The revised Xbox One Kinect, also known as the Microsoft Kinect V2 for Windows, includes enhanced hardware which may improve its utility as a gait assessment tool. This study examined the concurrent validity and inter-day reliability of spatiotemporal and kinematic gait parameters estimated using the Kinect V2 automated body tracking system and a criterion reference three-dimensional motion analysis (3DMA) marker-based camera system. Thirty healthy adults performed two testing sessions consisting of comfortable and fast paced walking trials. Spatiotemporal outcome measures related to gait speed, speed variability, step length, width and time, foot swing velocity and medial-lateral and vertical pelvis displacement were examined. Kinematic outcome measures including ankle flexion, knee flexion and adduction and hip flexion were examined. To assess the agreement between Kinect and 3DMA systems, Bland-Altman plots, relative agreement (Pearson's correlation) and overall agreement (concordance correlation coefficients) were determined. Reliability was assessed using intraclass correlation coefficients, Cronbach's alpha and standard error of measurement. The spatiotemporal measurements had consistently excellent (r≥0.75) concurrent validity, with the exception of modest validity for medial-lateral pelvis sway (r=0.45-0.46) and fast paced gait speed variability (r=0.73). In contrast kinematic validity was consistently poor to modest, with all associations between the systems weak (r<0.50). In those measures with acceptable validity, the inter-day reliability was similar between systems. In conclusion, while the Kinect V2 body tracking may not accurately obtain lower body kinematic data, it shows great potential as a tool for measuring spatiotemporal aspects of gait.

The study of workers' health problems possibly associated with stressful conditions requires valid and reliable tools for monitoring risk factors. The present study validates two questionnaires to assess psychosocial risk factors for stress-related illnesses within a sample of Colombian workers. The validation process was based on a representative sample survey of 2,360 Colombian employees, aged 18-70 years. Worker response rate was 90%; 46% of the responders were women. Internal consistency was calculated, construct validity was tested with factor analysis and concurrent validity was tested with Spearman correlations. The questionnaires demonstrated adequate reliability (0.88-0.95). Factor analysis confirmed the dimensions proposed in the measurement model. Concurrent validity resulted in significant correlations with stress and health symptoms. "Work and Non-work Psychosocial Factors Questionnaires" were found to be valid and reliable for the assessment of workers' psychosocial factors, and they provide information for research and intervention.

A motor skills assessment could be helpful in talent development by estimating essential perceptuo-motor skills of young players, which are considered requisite to develop excellent technical and tactical qualities. The Netherlands Table Tennis Association uses a motor skills assessment in their talent development programme consisting of eight items measuring perceptuo-motor skills specific to table tennis under varying conditions. This study aimed to investigate this assessment regarding its reproducibility, internal consistency, underlying dimensions and concurrent validity in 113 young table tennis players (6-10 years). Intraclass correlation coefficients of six test items met the criteria of 0.7 with coefficients of variation between 3% and 8%. Cronbach's alpha valued 0.853 for internal consistency. The principal components analysis distinguished two conceptually meaningful factors: "ball control" and "gross motor function." Concurrent validity analyses demonstrated moderate associations between the motor skills assessment's results and national ranking; boys r = -0.53 (P < 0.001) and girls r = -0.45 (P = 0.015). In conclusion, this evaluation demonstrated six test items with acceptable reproducibility, good internal consistency and good prospects for validity. Two test items need revision to upgrade reproducibility. Since the motor skills assessment seems to be a reproducible, objective part of a talent development programme, more longitudinal studies are required to investigate its predictive validity.

Residual symptoms of depression are related to more severe and chronic course of functional impairment with higher risk of relapse. The objective of this study was to validate, and determine psychometric properties of the Korean version of Depression Residual Symptom Scale (KDRSS). A total of 203 outpatients with recent episode of major depression based on DSM-IV criteria were enrolled in this study. They had been treated with antidepressants and assessed by KDRSS, Hamilton Depression Rating Scale-24 (HDRS-24), and Montgomery-Åsberg Depression Rating Scale (MARDS). The validity and reliability of KDRSS were assessed, including internal consistency reliability, concurrent validity, temporal stability, factorial validity, and discriminative validity. Internal consistency (Cronbach's alpha=0.961), concurrent validity (MADRS: r=0.731, p<0.01, HDRS-24: r=0.663, p<0.01), and temporal stability (r=0.726, p<0.01) of KDRSS were all excellent. KDRSS showed good discriminative validity based on MARDS. KDRSS consisted of one-factor structure accounting for 63.8% of total variance. All subjects except two in full remission group had one or more residual symptoms. In 7 subscales of KDRSS consisting of similar items respectively, 'lack of energy' was the most commonly reported, followed by 'increased emotionalism' in this group. KDRSS is a useful and sensitive instrument for measuring residual depressive symptoms. Since some depressive symptoms including 'lack of energy' and 'increased emotionalism' in patients with full remission might be persistent during psychiatric intervention, these symptoms need to be focused on in clinical practice.

Medication non-adherence is a prevalent problem worldwide but up to today, no gold standard is available to assess such behavior. This study was to evaluate the psychometric properties, particularly the concurrent validity of the English version of the Malaysian Medication Adherence Scale (MALMAS) among people with type 2 diabetes in Malaysia. Individuals with type 2 diabetes, aged 21 years and above, using at least one anti-diabetes agent and could communicate in English were recruited. The MALMAS was compared with the 8-item Morisky Medication Adherence Scale (MMAS-8) to assess its convergent validity while concurrent validity was evaluated based on the levels of glycated hemoglobin (HbA1C). Participants answered the MALMAS twice: at baseline and 4 weeks later. The study involved 136 participants. The MALMAS achieved acceptable internal consistency (Cronbach's alpha=0.565) and stable reliability as the test-retest scores showed fair correlation (Spearman's rho=0.412). The MALMAS has good correlation with the MMAS-8 (Spearman's rho=0.715). Participants who were adherent to their anti-diabetes medications had significantly lower median HbA1C values than those who were non-adherence (7.90 versus 8.55%, p=0.032). The odds of participants who were adherent to their medications achieving good glycemic control was 3.36 times (95% confidence interval: 1.09-10.37) of those who were non-adherence. This confirms the concurrent validity of the MALMAS. The sensitivity of the MALMAS was 88.9% while its specificity was 29.6%. The findings of this study further substantiates the reliability and validity of the MALMAS, in particular its concurrent validity and sensitivity for assessing medication adherence of people with type 2 diabetes in Malaysia.

To validate the SQLS scale in Colombian patients diagnosed with schizophrenia. The self-report scale was applied to 251 patients. Measures of test-retest reliability, internal consistency and correlation inter-scales with the SF-12 were made by applying the scale 2 days later in 28 patients, and 30 days later in 38; 50 patients filled-out the SF-12 scale to determine the concurrent validity. Three domains were found with all of them having Cronbach's alphas >0.7. The three factors model did not show adequate fit indexes. Test-retest evaluation showed satisfactory correlation values (>0.86). Sensitivity to change did not shown significant differences between the repeated measures. As regards concurrent validity, acceptable correlation values were found only in SF-12 domains related to mental health and functioning. The SQLS has a factorial structure consistent with previous reports, adequate internal consistency and temporal stability. However, a more detailed examination of some of these items is required, considering that the measurement of the construct does not appear to be adequate.

2002-06-01

The Self-rating Inventory for Posttraumatic Stress Disorder of 22 items was developed for use with populations without identified traumatic experiences. The inventory has been used extensively in survey research in The Netherlands. This paper examines the psychometric properties. In four different groups (trauma and psychiatric patients, elderly Dutch subjects, former peacekeepers, and medical students) internal consistency, test-retest reliability, concurrent and discriminant validity, and sensitivity and specificity are analyzed. The inventory showed good internal consistency, test-retest reliability, concurrent and discriminant validity, and high sensitivity and specificity. It appears to be valuable for survey research on posttraumatic stress in nonselected populations. As a screening device, high sensitivity for PTSD symptoms is evident even when the traumatic event has not been defined.

This study aimed to validate a 6-item 1-factor global measure of social support developed from the Medical Outcomes Study Social Support Survey (MOS-SSS) for use in large epidemiological studies. Data were obtained from two large population-based samples of participants in the Australian Longitudinal Study on Women's Health. The two cohorts were aged 53-58 and 28-33 years at data collection (N = 10,616 and 8,977, respectively). Items selected for the 6-item 1-factor measure were derived from the factor structure obtained from unpublished work using an earlier wave of data from one of these cohorts. Descriptive statistics, including polychoric correlations, were used to describe the abbreviated scale. Cronbach's alpha was used to assess internal consistency and confirmatory factor analysis to assess scale validity. Concurrent validity was assessed using correlations between the new 6-item version and established 19-item version, and other concurrent variables. In both cohorts, the new 6-item 1-factor measure showed strong internal consistency and scale reliability. It had excellent goodness-of-fit indices, similar to those of the established 19-item measure. Both versions correlated similarly with concurrent measures. The 6-item 1-factor MOS-SSS measures global functional social support with fewer items than the established 19-item measure.

This study aimed to analyze the psychometric properties of the Spanish version of the Voice Activity and Participation Profile (SVAPP) questionnaire. A randomized, cross-sectional sampling strategy with controls was used. Two samples with a total of 169 participants were analyzed, specifically 61 men (mean age 37.02) and 108 women (mean age 37.78). Of these participants, 112 were patients and 57 were controls. The instrument was submitted to reliability (internal consistency and corrected item-total correlations) and reproducibility analyses. Validation assessment was based on the construct validity, convergent validity, discriminant validity, and concurrent validity. The global internal consistency was excellent (Cronbach's α = 0.976), corrected item-total correlations were satisfactory and ranged 0.63-0.89, and factor loadings were above 0.50. The different subscales showed good internal consistency (alpha coefficients ranged 0.830-0.956) and test-retest values were consistently associated. The exploratory factor analysis evidenced a strongly defined five factors internal structure, with factors loadings ranging 0.51-0.86. Convergent validity demonstrated that all subscales and scores were very strongly correlated (Pearson r above 0.735) and significantly associated. The discriminant validity analysis showed that SVAPP had good specificity to distinguish dysphonic from healthy voice subjects. Concurrent validity with Voice Handicap Index Spanish version (SVHI) showed very strong correlations between total scores, and between SVHI total score and SVAPP Daily and Social Communication subscales; correlations between both tests subscales were strong; only between SVAPP Work and SVHI Physical sections correlations were moderate. The findings of the present study demonstrated evidence for the SVAPP questionnaire reliability and validity, and provided insightful implications of voice disorders on Spanish patients' quality of life. However, further investigations are required. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

The eight-item Brief Illness Perception Questionnaire is used as a screening instrument in physical therapy to assess mental defeat in patients with acute low back pain, besides patient perception might determine the course and risk for chronic low back pain. However, the psychometric properties of the Brief Illness Perception Questionnaire in common musculoskeletal disorders like acute low back pain have not been adequately studied. Patients' perceptions vary across different populations and affect coping styles. Thus, our aim was to determine the internal consistency, test-retest reliability and validity of the Dutch language version of the Brief Illness Perception Questionnaire in acute non-specific low back pain patients in primary care physical therapy. A non-experimental cross-sectional study with two measurements was performed. Eighty-four acute low back pain patients, in multidisciplinary health care center in Dutch primary care with a sample mean (SD) age of 42 (12) years, participated in the study. Internal consistency (Cronbach's α) and test-retest procedures (Intraclass Correlation Coefficients and limits of agreement) were evaluated at a one-week interval. The concurrent validity of the Brief Illness Perception Questionnaire was examined by using the Mental Health Component of the Short Form 36 Health Survey. The Cronbach's α for internal consistency was 0.73 (95% CI, 0.67 - 0.83); and the Intraclass Correlation Coefficient test-retest reliability was acceptable: 0.72 (95% CI, 0.53 - 0.82), however, the limits of agreement were large. The Intraclass Correlation Coefficient measuring concurrent validity 0.65 (95% CI, 0.46 - 0.80). The Dutch version of the Brief Illness Perception Questionnaire is an appropriate instrument for measuring patients' perceptions in acute low back pain patients, showing acceptable internal consistency and reliability. Concurrent validity is adequate, however, the instrument may be unsuitable for detecting changes in low back pain perception over time.

The aim of this study was to develop the Mayo Dysphagia Questionnaire-30 Day (MDQ-30), a tool to measure esophageal dysphagia, by adapting items from validated instruments for use in clinical trials, and assess its feasibility, reproducibility, and concurrent validity. Outpatients referred to endoscopy for dysphagia or seen in a specialty clinic were recruited. Feasibility testing was done to identify problematic items. Reproducibility was measured by test-retest format. Concurrent validity reflects agreement between information gathered in a structured interview versus the patients' written responses. The MDQ-30, a 28-item instrument, took 10 min (range = 5-30 min) to complete. Four hundred thirty-one outpatients [210 (49%) men; mean age = 61 years] participated. Overall, most concurrent validity kappa values for dysphagia were very good to excellent with a median of 0.78 (min 0.28, max 0.95). The majority of reproducibility kappa values for dysphagia were moderate to excellent with a median kappa value of 0.66 (min 0.07, max 1.0). Overall, concurrent validity and reproducibility kappa values for gastroesophageal reflux disease (GERD) symptoms were 0.81 (95% CI = 0.72, 0.91) and 0.66 (95% CI = 0.55, 0.77), respectively. Individual item percent agreement was generally very good to excellent. Internal consistency was excellent. We conclude that the MDQ-30 is an easy-to-complete tool to evaluate reliably dysphagia symptoms over the last 30 days.

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

To cross-culturally adapt and validate the Greek version of the Kujala anterior knee pain scale (KAKPS). The Greek KAKPS was translated from the original English version following standard forward and backward translation procedures. The survey was then conducted in clinical settings by a questionnaire comprising the Greek KAKPS and patellofemoral pain syndrome (PFPS) severity scale. A total of 130 (62 women and 68 men) Greek-reading patients between 18 and 45 years old with anterior knee pain (AKP) for at least four weeks were recruited from physical therapy clinics. To establish test-retest reliability, the patients were asked to complete the KAKPS at initial visit and 2-3 days after the initial visit. The Greek version of the PFPS severity scale was also administered once at initial visit. Internal consistency of the translated instrument was measured using Cronbach's α. An intraclass correlation coefficient was used to assess the test-retest reliability of the KAKPS. Concurrent validity was measured by correlating the KAKPS with the PFPS severity scale using Pearson's correlation coefficient. The results showed that the Greek KAKPS has good internal consistency (Cronbach's α = 0.942), test-retest reliability (ICC = 0.921) and concurrent validity (r > 0.7). This study has shown that the Greek KAKPS has good internal consistency, test-retest reliability and concurrent validity when correlated with the PFPS severity scale in adult patients with AKP for at least four weeks. Implications for rehabilitation The Greek version of the KAKPS has been found to be reliable and valid when used in adult patients with AKP for at least four weeks. The results of the psychometric characteristics were compatible with those of the original English version. The KAKPS could be applied in a Greek-speaking population to assess functional limitations and symptoms in patients aged 18-45 years old with AKP for at least four weeks.

To examine the validity and reliability of the Chinese (Cantonese) version of the Hierarchic Dementia Scale (CV-HDS) for Chinese older persons in Hong Kong. The HDS was translated into Cantonese Chinese. The content and cultural validity were evaluated by six expert panel members. Sixty-two participants with diagnosis of dementia were recruited for evaluation. Inter-rater reliability, test-retest reliability, internal consistency and concurrent validity were examined. The CV-HDS demonstrated satisfactory psychometric properties. inter-rater reliability and test-retest reliability were high (alpha=0.89 and alpha=0.94 respectively). High value of Cronbach's alpha (alpha=0.94) demonstrated good internal consistency. The concurrent validity of CV-HDS, through correlation with its scores with that of the Chinese version of Mini Mental Status Examination, was established (ranged from r=0.58 to r=0.78, p<0.01). The CV-HDS is a reliable and valid instrument for assessing severity of cognitive impairment in Cantonese speaking Chinese people with dementia. It facilitates treatment planning to optimize the effects of functional training and rehabilitation.

The Leicester Cough Questionnaire (LCQ) has been validated for assessing cough-specific health status in bronchiectasis. We translated the LCQ into Mandarin Chinese and investigated its validity, reliability and responsiveness. The LCQ was translated into Mandarin Chinese using the forward-backward translation procedure. A total of 144 out-patients completed the Mandarin Chinese version of the LCQ (LCQ-MC), the Hospital Anxiety and Depression Scale (HADS) and the St George's Respiratory Questionnaire. Reassessments were performed during exacerbations and at 6 months. Concurrent validation, internal consistency, repeatability and responsiveness were determined. Minor cultural adaptations were made to the wording of LCQ-MC. No other difficulties were found during the translation process, with all items easily adapted to acceptable Mandarin Chinese. The questionnaire was not changed in terms of content layout and the order of the questions. In cognitive debriefing interviews, participants reported that the questionnaire was acceptable, relevant, comprehensive and easy to complete. The LCQ-MC showed good concurrent validity, internal consistency and test-retest reliability. Responsiveness was shown by significant changes in LCQ-MC scores between steady state, the first exacerbation and following 2-week antibiotic treatment (both interval changes, P < 0.01) CONCLUSION: The LCQ-MC is a valid, reliable and responsive instrument for determining cough-specific health status in Chinese bronchiectasis patients.

Background: Functioning Assessment Short Test (FAST) is a brief instrument designed to assess the main functioning problems experienced by psychiatric patients, specifically bipolar patients. It includes 24 items assessing impairment or disability in six domains of functioning: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships and leisure time. The aim of this study is to measure the validity and reliability of the Italian version of this instrument. Methods: Twenty-four patients with DSM-IV TR bipolar disorder and 20 healthy controls were recruited and evaluated in three private clinics in Cagliari (Sardinia, Italy). The psychometric properties of FAST (feasibility, internal consistency, concurrent validity, discriminant validity (patients vs controls and eutimic patients vs manic and depressed), and test-retest reliability were analyzed. Results: The internal consistency obtained was very high with a Cronbach's alpha of 0.955. A highly significant negative correlation with GAF was obtained (r = -0.9; p < 0.001) pointing to a reasonable degree of concurrent validity. FAST show a good test-retest reliability between two independent evaluation differing of one week (mean K =0.73). The total FAST scores were lower in controls as compared with Bipolar Patients and in Euthimic patients compared with Depressed or Manic. Conclusion: The Italian version of the FAST showed similar psychometrics properties as far as regard internal consistency and discriminant validity of the original version and show a good test retest reliability measure by means of K statistics.

The purpose of the study is to develop a Japanese version of the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scales Young Adult Version (PedsQL-YA-J) and determine the feasibility, reliability, and validity of the scales. Translation equivalence and content validity were verified using back-translation and cognitive debriefing tests. A total of 428 young adults recruited from one university, two vocational schools, or five companies completed questionnaires. We determined questionnaire feasibility, internal consistency, and test-retest reliability; checked concurrent validity against the Center for Epidemiologic Studies Depression Scale (CES-D); determined convergent and discriminant validity with the Medical Outcome Study 36-item Short Form Health Survey (SF-36); described known-groups validity with regard to subjective symptoms, illness or injury requiring regular medical visits, and depression; and verified factorial validity. All scales were internally consistent (Cronbach's coefficient alpha = 0.77-0.86); test-retest reliability was acceptable (intraclass correlation coefficient = 0.57-0.69); and all scales were concurrently valid with depression (Pearson's correlation coefficient = 0.43-0.57). The scales convergent and discriminant validity with the SF-36 and CES-D were acceptable. Evaluation of known-groups validity confirmed that the Physical Functioning scale was sensitive for subjective symptoms, the Emotional Functioning scale for depression, and the Work/School Functioning scale for illness or injury requiring regular medical visits. Exploratory factor analysis found a six-factor structure consistent with the assumed structure (cumulative proportion = 57.0%). The PedsQL-YA-J is suitable for assessing health-related quality of life in young adults in education, employment, or training, and for clinical trials and epidemiological research.

Although the significant scientific advances on place attachment literature, no instruments exist specifically developed or adapted to residential care. 410 adolescents (11 - 18 years old) participated in this study. The place attachment scale evaluates five dimensions: Place identity, Place dependence, Institutional bonding, Caregivers bonding and Friend bonding. Data analysis included descriptive statistics, content validity, construct validity (Confirmatory Factor Analysis), concurrent validity with correlations with satisfaction with life and with institution, and reliability evidences. The relationship with individual characteristics and placement length was also verified. Content validity analysis revealed that more than half of the panellists perceive all the items as relevant to assess the construct in residential care. The structure with five dimensions revealed good fit statistics and concurrent validity evidences were found, with significant correlations with satisfaction with life and with the institution. Acceptable values of internal consistence and specific gender differences were found. The preliminary psychometric properties of this scale suggest it potential to be used with youth in care.

This is a clinic-based cross-sectional study involving 2 health-related quality-of-life (HRQL) questionnaires. To compare the score distribution and reliability of the spinal deformity specific Scoliosis Research Society-22r (SRS-22r) questionnaire and the established generic Child Health Questionnaire-CF87 (CHQ-CF87), and to assess the concurrent validity of the SRS-22r using the CHQ-CF87 in an adolescent spine deformity population. Different questionnaires are commonly thought to be necessary to assess the HRQL of adolescent and adult populations. But since spinal deformities usually begin in the second decade of life, longitudinal follow-up with the same HRQL is desirable. The SRS-22r HRQL has recently been validated for score distribution and internal consistency in a spinal deformity population ranging in age from 7 to 78 years. The SRS-22r and CHQ-CF87 HRQLs were completed by 70 orthopedic spinal deformity outpatients 8 to 18 years of age, of whom 54 returned mailed retest questionnaires at an average of 24 days later. The ceiling effect averaged 27% for the SRS-22r and 36% for the CHQ-CF87. Respective values for internal consistency (Cronbach alpha) were 0.81 and 0.82, and for test-retest reproducibility the intraclass correlations (ICC) were 0.73 and 0.61. Concurrent validity was r > or = 0.68 or more for relevant function, pain, and mental health domains. The SRS Self-Image and particularly the Satisfaction/Dissatisfaction with Management domains did not correlate well with any CHQ-CF87 domains (r = 0.50 and 0.30, respectively). In a spinal deformity population 8 to 18 years of age, the score distribution and reliability, internal consistency, and reproducibility of the SRS-22r were at least as good as the CHQ-CF87. The SRS-22r function, pain, and mental health domains were concurrently valid in comparison to relevant CHQ-CF87 domains, but the SRS-22r self-image and satisfaction/dissatisfaction domains were not, thereby providing health-related quality-of-life information not provided for by the CHQ-CF87.

Two instrument validation studies broadened the research literature exploring the factor structure, internal consistency reliability, and concurrent validity of scores on the Social Anxiety and Depression Life Interference—24 Inventory (SADLI-24; Osman, Bagge, Freedenthal, Guiterrez, & Emmerich, 2011). Study 1 (N = 1065) was undertaken to concurrently appraise three competing factor models for the instrument: a unidimensional model, a two-factor oblique model and a bifactor model. The bifactor model provided the best fit to the study sample data. Study 2 (N = 220) extended the results from Study 1 with an investigation of the convergent and discriminant validity for the bifactor model of the SADLI-24 with multiple regression analyses and scale-level exploratory structural equation modeling. This project yields data that augments the initial instrument development investigations for the target measure. PMID:28781401

This study evaluates the reliability and validity of the strategies for weight management (SWM) measure, a questionnaire that assesses weight management strategies for adults. The SWM includes 20 items that are categorized within the following subscales: (1) energy intake, (2) energy expenditure, (3) self-monitoring, and (4) self-regulation. Baseline and 6-month data were collected from 404 overweight/obese adults (mean age=22±3.8 years, 68% ethnic minority) enrolled in a randomized controlled trial aiming to reduce weight by improving diet and physical activity behaviours. Reliability and validity were assessed for each subscale separately. Cronbach alpha was conducted to assess reliability. Concurrent, construct I (sensitivity to the study treatment condition), and construct II (relationship to the outcomes) validity were assessed using linear regressions with the following outcome measures: weight, self-reported diet, and weekly energy expenditure. All subscales showed strong internal consistency. The strength of the validity evidence depended on subscale and validity type. The strongest validity evidence was concurrent validity of the energy intake and energy expenditure subscales; construct I validity of the energy intake and self-monitoring subscales; and construct II validity of the energy intake, energy expenditure, and self-regulation subscales. Results indicate that the SWM can be used to assess weight management strategies among an ethnically diverse sample of adults as each subscale showed evidence of reliability and select types of validity. As validity is an accumulation of evidence over multiple studies, this study provides initial reliability and validity evidence in one population segment.

Spanish is one of the five most spoken languages in the world. There is currently no published Spanish version of the Örebro Musculoskeletal Pain Questionnaire (OMPQ). The aim of the present study is to describe the process of translating the OMPQ into Spanish and to perform an analysis of reliability, internal structure, internal consistency and concurrent criterion-related validity. Translation and psychometric testing. Two independent translators translated the OMPQ into Spanish. From both translations a consensus version was achieved. A backward translation was made to verify and resolve any semantic or conceptual problems. A total of 104 patients (67 men/37 women) with a mean age of 53.48 (±11.63), suffering from chronic musculoskeletal disorders, twice completed a Spanish version of the OMPQ. Statistical analysis was performed to evaluate the reliability, the internal structure, internal consistency and concurrent criterion-related validity with reference to the gold standard questionnaire SF-12v2. All variables except "Coping" showed a rate above 0.85 on reliability. The internal structure calculation through exploratory factor analysis indicated that 75.2% of the variance can be explained with six components with an eigenvalue higher than 1 and 52.1% with only three components higher than 10% of variance explained. In the concurrent criterion-related validity, several significant correlations were seen close to 0.6, exceeding that value in the correlation between general health and total value of the OMPQ. The Spanish version of the screening questionnaire OMPQ can be used to identify Spanish patients with musculoskeletal pain at risk of developing a chronic disability.

Physicians play a major role as teachers in undergraduate medical education. Studies indicate that different forms and degrees of motivation can influence work performance in general and that teachers' motivation to teach can influence students' academic achievements in particular. Therefore, the aim of this study was to develop and to validate an instrument measuring teaching motivations in hospital-based physicians. We chose self-determination theory as a theoretical framework for item and scale development. It distinguishes between different dimensions of motivation depending on the amount of self-regulation and autonomy involved and its empirical evidence has been demonstrated in other areas of research. To validate the new instrument (PTMQ = Physician Teaching Motivation Questionnaire), we used data from a sample of 247 physicians from internal medicine and surgery at six German medical faculties. Structural equation modelling was conducted to confirm the factorial structure, correlation analyses and linear regressions were performed to examine concurrent and incremental validity. Structural equation modelling confirmed a good global fit for the factorial structure of the final instrument (RMSEA = .050, TLI = .957, SRMR = .055, CFI = .966). Cronbach's alphas indicated good internal consistencies for all scales (α = .75 - .89) except for the identified teaching motivation subscale with an acceptable internal consistency (α = .65). Tests of concurrent validity with global work motivation, perceived teaching competence, perceived teaching involvement and voluntariness of lesson allocation delivered theory-consistent results with slight deviations for some scales. Incremental validity over global work motivation in predicting perceived teaching involvement was also confirmed. Our results indicate that the PTMQ is a reliable, valid and therefore suitable instrument for assessing physicians' teaching motivation.

The purpose of this research is to verify the reliability and validity of a job stressor scale for nurses caring for patients with intractable neurological diseases. A mail survey was conducted using a self-report questionnaire. The subjects were 263 nurses and assistant nurses working in wards specializing in intractable neurological diseases. The response rate was 71.9% (valid response rate, 66.2%). With regard to reliability, internal consistency and stability were assessed. Internal consistency was examined via Cronbach's alpha. For stability, the test-retest method was performed and stability was examined via intraclass correlation coefficients. With regard to validity, factor validity, criterion-related validity, and content validity were assessed. Exploratory factor analysis was used for factor validity. For criterion-related validity, an existing scale was used as an external criterion; concurrent validity was examined via Spearman's rank correlation coefficients. As a result of analysis, there were 26 items in the scale created with an eight factor structure. Cronbach's a for the 26 items was 0.90; with the exception of two factors, alpha for all of the individual sub-factors was high at 0.7 or higher. The intraclass correlation coefficient for the 26 items was 0.89 (p < 0.001). With regard to criterion-related validity, concurrent validity was confirmed and the correlation coefficient with an external criterion was 0.73 (p < 0.001). For content validity, subjects who responded that "The questionnaire represents a stressor well or to a degree" accounted for 81% of the total responses. Reliability and validity were confirmed, so the scale created in the current research is a usable scale.

Development and validation of the occupational identity scale.

Ego-identity research utilizing Marcia's (1966) identity statuses has been prolific during the past 15 years. The four types of statuses--achievement, moratorium, foreclosure, diffusion--have become part of the ego-identity development theory. The development of a research tool to study further one of the dimensions of ego-identity development (occupational dimension) was perceived as a need. Therefore, items were created utilizing the criteria established by previous research and content validated by a group of experts. These statements were validated by 417 students from six high schools and colleges. Responses were analyzed and measures of construct and concurrent validity were obtained. Also indexes of internal consistency and item discrimination were estimated. Through factor analysis techniques, four factors were identified for the occupational identity statuses. They accounted for 49 per cent of the total variance. Reliability coefficients ranged between 0.70 and 0.87. Concurrent validity coefficients ranged between 0.38 and 0.79, when correlated with a similar instrument. After deletion of those items that did not contribute significantly to the validity of the instrument, a 28-item Occupational Identity Scale was established.

The purpose of this study was to develop and validate a questionnaire assessing food liking in a French-Canadian population. A questionnaire was developed, in which participants were asked to rate their degree of liking of 50 food items. An expert panel evaluated the content validity. For the validation study, 150 men and women completed the questionnaire twice. An Exploratory Factor Analysis (EFA) was performed to assess the number of subscales of the questionnaire. Internal consistency and test-retest reliability of the subscales were evaluated. Concurrent validity was assessed through correlations between liking scores and self-reported frequencies of consumption. Comments from the experts led to changes in the list of foods included in the questionnaire. The EFA revealed a two-factor structure for the questionnaire (i.e., savory and sweet foods) and led to the removal of nine items, resulting in a 32-item questionnaire. The two subscales revealed good internal consistency (Cronbach alphas: 0.85 and 0.89) and test-retest reliability (p = 0.84 and 0.86). The questionnaire demonstrated adequate concurrent validity, with moderate correlations between food liking and self-reported frequency of consumption (r = 0.19–0.39, ps < 0.05). This new Food Liking Questionnaire assessing liking of a variety of savory and sweet foods demonstrated good psychometric properties in every validation step. This questionnaire will be useful to explore the role of food liking and its interactions with other factors in predicting eating behaviors and energy intake. PMID:29292754

The aims of this study were to translate the Cardiff Acne Disability Index (CADI) into Serbian and to assess its validity and reliability in Serbian acne patients. The CADI was translated and linguistically validated into Serbian according to published guidelines. This version of CADI, along with the Serbian version of Children's Dermatology Life Quality Index (CDLQI) and a short demographic questionnaire, was administrated to a cohort of secondary school pupils. The Global Acne Grading Score was used to measure the clinical severity of acne. The internal consistency reliability of the Serbian version of CADI was assessed by Cronbach's alpha coefficient while its concurrent validity was assessed by Spearman's correlation coefficient. Construct validity was examined by factor analysis. A total of 465 pupils completed questionnaires. Self-reported acne was present in 76% of pupils (353/465). The Serbian version of CADI showed high internal consistency reliability (Cronbach's alpha coefficient = 0.79). The mean item-total correlation coefficient was 0.74 with a range of 0.53-0.81. The concurrent validity of the scale was supported by a moderate but highly significant correlation with the CDLQI (Spearman's rho = 0.66; P < 0.001). Factor analysis revealed the presence of two dimensions underlying the factor structure of the scale. The Serbian version of the CADI is a reliable, valid, and valuable tool for assessing the impact of acne on the quality of life of Serbian-speaking patients.

This is a report of development and psychometric testing of the East Asian Acculturation Measure-Chinese version (EAAM-C) scale. An instrument validation design with a cross-sectional survey was conducted. The process was carried in two phases. In Phase 1, Barry's East Asian Acculturation Measure was translated and back translated to evaluate its content, face validity, and feasibility validity. In Phase 2, the 16-item EAAM-C was pilot-tested among 485 female immigrants for test-retest reliability, internal consistency, theoretically-supported construct validity and concurrent validity. The pilot work and the survey results indicated the tools possessed adequate content and face validity. The Cronbach's Alphas for the EAAM-C was 0.72, and 0.76-0.79 for its subscales, and the correlation of test-retest reliability (at 3 weeks) was 0.75. After dropping one item, four theoretically-supported factors which explained 61.82% of the variance were abstracted using exploratory factor analysis: assimilation, integration, separation, and marginalization. Based on the underlying four-factor theoretical structures of the EAAM, the confirmatory factor analysis of the EAAM-C was further examined. The analysis revealed that the four-factor model was an acceptable fit for the data which demonstrated adequate finding in its construct validity. These factors were inter-correlated, and showed statistically significant correlation with the Chinese Health Questionnaire, indicating adequate concurrent validity. The scale shows acceptable validity and consistency, and suggests that immigrant acculturation is a complex construct. This quick evaluation instrument can be applied to assess clients' acculturation and in further developing certain interventions to improve their health.

Objective To examine the test-retest reliability and concurrent validity of variability of gait characteristics. Design Cross-sectional study. Setting Research laboratory. Participants Older adults (N=558) from the Cardiovascular Health Study. Interventions Not applicable. Main Outcome Measures Gait characteristics were measured using a 4-m computerized walkway. SD determined from the steps recorded were used as the measures of variability. Intraclass correlation coefficients (ICC) were calculated to examine test-retest reliability of a 4-m walk and two 4-m walks. To establish concurrent validity, the measures of gait variability were compared across levels of health, functional status, and physical activity using independent t tests and analysis of variances. Results Gait variability measures from the two 4-m walks demonstrated greater test-retest reliability than those from the single 4-m walk (ICC=.22–.48 and ICC=.40–.63, respectively). Greater step length and stance time variability were associated with poorer health, functional status and physical activity (P<.05). Conclusions Gait variability calculated from a limited number of steps has fair to good test-retest reliability and concurrent validity. Reliability of gait variability calculated from a greater number of steps should be assessed to determine if the consistency can be improved. PMID:19061741

Badminton requires open and fast actions toward the shuttlecock, but there is no specific agility test for badminton players with specific movements. To develop an agility test that simultaneously assesses perception and motor capacity and examine the test's concurrent and construct validity and its test-retest reliability. The Badcamp agility test consists of running as fast as possible to 6 targets placed on the corners and middle points of a rectangular area (5.6 × 4.2 m) from the start position located in the center of it, following visual stimuli presented in a luminous panel. The authors recruited 43 badminton players (17-32 y old) to evaluate concurrent (with shuttle-run agility test--SRAT) and construct validity and test-retest reliability. Results revealed that Badcamp presents concurrent and construct validity, as its performance is strongly related to SRAT (ρ = 0.83, P < .001), with performance of experts being better than nonexpert players (P < .01). In addition, Badcamp is reliable, as no difference (P = .07) and a high intraclass correlation (ICC = .93) were found in the performance of the players on 2 different occasions. The findings indicate that Badcamp is an effective, valid, and reliable tool to measure agility, allowing coaches and athletic trainers to evaluate players' athletic condition and training effectiveness and possibly detect talented individuals in this sport.

The STarT Back Tool uses prognostic indicators to classify patients with low back pain into three risk groups to guide early secondary prevention in primary care. The present study aimed to evaluate the psychometric properties of the Japanese version of the tool (STarT-J). An online survey was conducted among Japanese patients with low back pain aged 20-64 years. Reliability was assessed by examining the internal consistency of the overall and psychosocial subscales using Cronbach's alpha coefficients. Spearman's correlation coefficients were used to evaluate the concurrent validity between the STarT-J total score/psychosocial subscore and standard reference questionnaires. Discriminant validity was evaluated by calculating the area under the curves (AUCs) for the total and psychosocial subscale scores against standard reference cases. Known-groups validity was assessed by examining the relationship between low back pain-related disability and STarT-J scores. The analysis included data for 2000 Japanese patients with low back pain; the mean (standard deviation [SD]) age was 47.7 (9.3) years, and 54.1% were male. The mean (SD) STarT-J score was 2.2 (2.1). The Cronbach's alpha coefficient was 0.75 for the overall scale and 0.66 for the psychosocial subscale. Spearman's correlation coefficients ranged from 0.30 to 0.59, demonstrating moderate to strong concurrent validity. The AUCs for the total score ranged from 0.65 to 0.83, mostly demonstrating acceptable discriminative ability. For known-groups validity, participants with more somatic symptoms had higher total scores. Those in higher STarT-J risk groups had experienced more low back pain-related absences. The overall STarT-J scale was internally consistent and had acceptable concurrent, discriminant, and known-groups validity. The STarT-J can be used with Japanese patients with low back pain.

To determine whether the SRS-22 fcv can be used in a population from France.

Use of SRS-22 fcv seems appropriate for evaluating adolescent idiopathic scoliosis in France. However, French-Canadian French is noticeably different from the French spoken in France, and no study has investigated the use of a French-Canadian version of a health-quality questionnaire in another French population. The methods used for validating the SRS-22 fcv in Quebec were adopted for use with a group of 200 adolescents with idiopathic scoliosis and 60 healthy adolescents in France. Reliability and reproducibility were measured by the Cronbach α and intraclass correlation coefficient (ICC), construct validity by factorial analysis, concurrent validity by the Short-Form of the survey, and discriminant validity by analysis of variance and multivariate linear regression. In France, the SRS-22 fcv showed good global internal consistency (Cronbach α = 0.87, intraclass correlation coefficient = 0.92), a coherent factorial structure, and high correlation coefficients between the SRS-22 fcv and Short-Form of the survey (P < 0.001). However, reliability and validity were slightly less than that for the instrument's original validation and the validation of the SRS-22 fcv in Quebec. These differences could be explained by language and cultural differences. The SRS-22 fcv is relevant for use in France, but further development and validation of a specific French questionnaire remain necessary to improve the assessment of functional outcomes of adolescents with scoliosis in France.

The Hospital Anxiety and Depression Scale (HADS) acts as one of the most frequently used self-reported measures in cancer practice. The evidence for construct validity of HADS, however, remains inconclusive. The objective of this study is to evaluate the psychometric properties of the Chinese version HADS (C-HADS) in terms of construct validity, internal consistency reliability, and concurrent validity in dyads of Chinese cancer patients and their family caregivers. This was a cross-sectional study, conducted in multiple centers: one hospital in each of the seven different administrative regions in China from October 2014 to May 2015. A total of 641 dyads, consisting of cancer patients and family caregivers, completed a survey assessing their demographic and background information, anxiety and depression using C-HADS, and quality of life (QOL) using Chinese version SF-12. Data analysis methods included descriptive statistics, confirmatory factor analysis (CFA), and Pearson correlations. Both the two-factor and one-factor models offered the best and adequate fit to the data in cancer patients and family caregivers respectively. The comparison of the two-factor and single-factor models supports the basic assumption of two-factor construct of C-HADS. The overall and two subscales of C-HADS in both cancer patients and family caregivers had good internal consistency and acceptable concurrent validity. The Chinese version of the HADS may be a reliable and valid screening tool, as indicated by its original two-factor structure. The finding supports the basic assumption of two-factor construct of HADS. Copyright © 2016 Elsevier Ltd. All rights reserved.

This study evaluates the psychometric performance of the Japanese version of the Overall Assessment of the Speaker's Experience of Stuttering for Adults (OASES-A), a comprehensive assessment tool of individuals who stutter. The OASES-A-J was administered to 200 adults who stutter in Japan. All respondents also evaluated their own speech (SA scale), satisfaction of their own speech (SS scale) and the Japanese translation version of the Modified Erickson Communication Attitude scale (S-24). The test-retest reliability and internal consistency of the OASES-A-J were assessed. To examine the concurrent validity of the questionnaire, Pearson correlation was conducted between the OASES-A-J Impact score and the S-24 scale, SA scale and SS scale. In addition, Pearson correlation among the impact scores of each section and total were calculated to examine the construct validity. The OASES-A-J showed a good test-retest reliability (r=0.81-0.95) and high internal consistency (α>0.80). Concurrent validity was moderate to high (0.55-0.75). Construct validity was confirmed by the relation between internal consistency in each section and correlation among sections' impact scores. Japanese adults showed higher negative impact for 'General Information', 'Reactions to Stuttering' and 'Quality of Life' sections. These results suggest that the OASES-A-J is a reliable and valid instrument to measure the impact of stuttering on Japanese adults who stutter. The OASES-A-J could be used as a clinical tool in Japanese stuttering field. Copyright © 2016 Elsevier Inc. All rights reserved.

Parents who are overwhelmed by the intensity and aversive nature of child negative affect — those who are experiencing flooding — may be less likely to react effectively and instead may focus on escaping the aversive situation, disciplining either overly permissively or punitively to escape quickly from child negative affect. However, there are no validated self-report measures of the degree to which parents experience flooding, impeding the exploration of these relations. Thus, we created and evaluated the Parent Flooding scale (PFS), assessing the extent to which parents believe their children's negative affect during parent-child conflicts is unexpected, overwhelming and distressing. We studied its factorial validity, reliability, and concurrent validity in a community sample of 453 couples with 3- to 7-year-old children (51.9% girls) recruited via random digit dialing. Confirmatory factor analyses indicated a one-factor solution with excellent internal consistency. Test-retest stability over an average of 5.6 months was high. Concurrent validity was suggested by the associations of flooding with parents’ aggression toward their children, overreactive and lax discipline, parenting satisfaction, and parents’ anger, as well as with child externalizing behavior and negative affect. Incrementally concurrent validity analyses indicated that flooding was a unique predictor of mothers’ and fathers’ overreactive discipline and fathers’ parent-child aggression and lax discipline, over and above the contributions of parents’ anger and children's negative affect. The present results support the psychometric validity of the PFS. PMID:26909682

To cross-culturally adapt a French version of the LEIPAD, a self-administered questionnaire assessing the health-related quality of life (HRQoL) in adults aged 65 years and over living at home, and to evaluate its psychometric properties. After having translated LEIPAD in accordance with guidelines, we studied psychometric properties: reliability and construct validity-factor analysis, relationships between items and scales, internal consistency, concurrent validity with the Medical Outcome Study Short-Form 36 and known-groups validity. The results obtained in a sample of 195 elderly from the general population showed very good acceptability, with response rates superior to 93 %. Exploratory factor analysis extracted eight factors providing a multidimensionality structure with five misclassifications of items in the seven theoretical scales. Good internal consistency (Cronbach's alpha ranging from 0.73 and 0.86) and strong test-retest reliability (ICCs higher than 0.80 for six scales and 0.70 for one) were demonstrated. Concurrent validity with the SF-36 showed small to strong expected correlations. This first evaluation of the French version of LEIPAD's psychometric properties provides evidence in construct validity and reliability. It would allow HRQoL assessment in clinical and common practice, and investigators would be able to take part in national and international research projects.

A cross-sectional observational study to determine the response distribution, internal consistency, and construct, concurrent, and discriminative validities of The Scoliosis Research Society-22 (SRS-22) Patient Questionnaire translated into Japanese as compared with the other language versions. To validate the Japanese version of SRS22. The SRS-22 was translated into several languages but yet not into Japanese. The Japanese SRS-22 and Medical Outcomes Study Short Form 36 were simultaneously administered to 114 adolescent idiopathic scoliosis patients. Exploratory factor analysis revealed a 4-factor structure, though several items were not loaded as theoretically expected. The originally constructed Japanese SRS-22 subscales and the English version showed similar response distribution. Internal consistency was fair but lower than that of the English version. The concurrent validity of the translated version, except for the self-image subscale, was supported using Medical Outcomes Study Short Form 36 subscales as a reference. The function scale differed significantly by curve angle magnitude and treatment status. The self-image score was the highest in patients under observation when curve angle was < 40 degrees, while postsurgical patients marked the highest scores when the angle > or = 40 degrees, respectively. The Japanese SRS-22 is valid and may be useful for clinical evaluation of Japanese scoliosis patients, though the self-image subscale may need further assessment.

This research consists of four studies on the initial reliability and validity of the Internalization of Asian American Stereotypes Scale (IAASS), a self-report instrument that measures the degree Asian Americans have internalized racial stereotypes about their own group. The results from the exploratory and confirmatory factor analyses support a stable four-factor structure of the IAASS: Difficulties with English Language Communication, Pursuit of Prestigious Careers, Emotional Reservation, and Expected Academic Success. Evidence for concurrent and discriminant validity is presented. High internal-consistency and test-retest reliability estimates are reported. A discussion of how this scale can contribute to research and practice regarding internalized stereotyping among Asian Americans is provided.

Working dog organisations, such as Guide Dogs, need to regularly assess the behaviour of the dogs they train. In this study we developed a questionnaire-style behaviour assessment completed by training supervisors of juvenile guide dogs aged 5, 8 and 12 months old (n = 1,401), and evaluated aspects of its reliability and validity. Specifically, internal reliability, temporal consistency, construct validity, predictive criterion validity (comparing against later training outcome) and concurrent criterion validity (comparing against a standardised behaviour test) were evaluated. Thirty-nine questions were sourced either from previously published literature or created to meet requirements identified via Guide Dogs staff surveys and staff feedback. Internal reliability analyses revealed seven reliable and interpretable trait scales named according to the questions within them as: Adaptability; Body Sensitivity; Distractibility; Excitability; General Anxiety; Trainability and Stair Anxiety. Intra-individual temporal consistency of the scale scores between 5-8, 8-12 and 5-12 months was high. All scales excepting Body Sensitivity showed some degree of concurrent criterion validity. Predictive criterion validity was supported for all seven scales, since associations were found with training outcome, at at-least one age. Thresholds of z-scores on the scales were identified that were able to distinguish later training outcome by identifying 8.4% of all dogs withdrawn for behaviour and 8.5% of all qualified dogs, with 84% and 85% specificity. The questionnaire assessment was reliable and could detect traits that are consistent within individuals over time, despite juvenile dogs undergoing development during the study period. By applying thresholds to scores produced from the questionnaire this assessment could prove to be a highly valuable decision-making tool for Guide Dogs. This is the first questionnaire-style assessment of juvenile dogs that has shown value in predicting the training outcome of individual working dogs.

The Cardiac Depression Scale (CDS) has been designed to measure depressive symptoms in patients with heart disease. There is no Arabic version of the CDS. We translated and validated the CDS in an Arabic sample of patients with heart disease. Forward and back translation of the CDS was followed by assessment of cultural relevance and content validity. The Arabic version of the CDS (A-CDS) and the Arabic version of the Hospital Anxiety and Depression Scale (A-HADS) were then administered to 260 Arab in-patients with heart disease from 18 Arabic countries. Construct validity was assessed using exploratory factor analysis with polychoric correlations. Internal consistency was assessed using ordinal reliability alpha and item-to-factor polychoric correlations. Concurrent validity was assessed using Pearson's correlation coefficient between the A-CDS and the depression subscale of the A-HADS (A-HADS-D). Cultural relevance and content validity of the A-CDS were satisfactory. Exploratory factor analysis revealed three robust factors, without cross-loadings, that formed a single dimension. Internal consistency was high (ordinal reliability alpha for the total scale and the three factors were .94, .91, .86, and .87, respectively; item-to-factor correlations ranged from .77 to .91). Concurrent validity was high (r=.72). The A-CDS demonstrated a closer to normal distribution of scores than the A-HADS-D. Sensitivity and specificity of the A-CDS were not objectively assessed. The A-CDS appears to be a valid and reliable instrument to measure depressive symptoms in a representative sample of Arab in-patients with heart disease. Copyright © 2016 Elsevier B.V.

2016-08-01

The aim of this research was to gain insight into the key stressors for Australian farming families. It is well established that the farming work environment consists of a number of unique stressors which arise from dependency on factors beyond an individual's control (e.g. climate conditions) as well as the overlap between work and family environments. Despite this, limited research has included family factors in the assessment of stress felt by farmers and their families. This research sought to develop a scale of stressors for farming families in an Australian sample. A survey design was used for validity and reliability studies. The validity study involved assessment of factor structure, concurrent validity and discriminant validity. The reliability study used a test-retest reliability design. Participants were recruited from across Australia (38% Queensland; 30% New South Wales) and multiple industries (43% beef; 27% broadacre cropping; 26% horticulture). The validity study involved 278 participants and the reliability study involved 53 participants. Development of a Farming Family Stressor scale. The generated Farming Family Stressor scale presented satisfactory levels of concurrent validity (e.g. r = .73 against the Farm Stress Survey total score), discriminant validity (e.g. r = -.42 to r = .53 against the Satisfaction with Life and Kessler-10 total scores, respectively), internal consistency (Cronbach's alpha >.90) and test-retest reliability (rho > .66). This research lends insight into the complexity of stressors for farming families and has implications for occupational health and mental health programs that seek to reduce stress and improve health outcomes for that group. © 2015 National Rural Health Alliance Inc.

Concurrent analysis: towards generalisable qualitative research.

PubMed

Snowden, Austyn; Martin, Colin R

2011-10-01

This study develops an original method of qualitative analysis coherent with its interpretivist principles. The objective is to increase the likelihood of achieving generalisability and so improve the chance of the findings being translated into practice. Good qualitative research depends on coherent analysis of different types of data. The limitations of existing methodologies are first discussed to justify the need for a novel approach. To illustrate this approach, primary evidence is presented using the new methodology. The primary evidence consists of a constructivist grounded theory of how mental health nurses with prescribing authority integrate prescribing into practice. This theory is built concurrently from interviews, reflective accounts and case study data from the literature. Concurrent analysis. Ten research articles and 13 semi-structured interviews were sampled purposively and then theoretically and analysed concurrently using constructivist grounded theory. A theory of the process of becoming competent in mental health nurse prescribing was generated through this process. This theory was validated by 32 practising mental health nurse prescribers as an accurate representation of their experience. The methodology generated a coherent and generalisable theory. It is therefore claimed that concurrent analysis engenders consistent and iterative treatment of different sources of qualitative data in a manageable manner. This process supports facilitation of the highest standard of qualitative research. Concurrent analysis removes the artificial delineation of relevant literature from other forms of constructed data. This gives researchers clear direction to treat qualitative data consistently raising the chances of generalisability of the findings. Raising the generalisability of qualitative research will increase its chances of informing clinical practice. © 2010 Blackwell Publishing Ltd.

Empathy plays a crucial role in healthy social functioning and in maintaining positive social relationships. In this study, 1250 children and adolescents (10–15 year olds) completed the newly developed Empathy Questionnaire for Children and Adolescents (EmQue-CA) that was tested on reliability, construct validity, convergent validity, and concurrent validity. The EmQue-CA aims to assess empathy using the following scales: affective empathy, cognitive empathy, and intention to comfort. A Principal Components Analysis, which was directly tested with a Confirmatory Factor Analysis, confirmed the proposed three-factor model resulting in 14 final items. Reliability analyses demonstrated high internal consistency of the scales. Furthermore, the scales showed high convergent validity, as they were positively correlated with related scales of the Interpersonal Reactivity Index (Davis, 1983). With regard to concurrent validity, higher empathy was related to more attention to others’ emotions, higher friendship quality, less focus on own affective state, and lower levels of bullying behavior. Taken together, we show that the EmQue-CA is a reliable and valid instrument to measure empathy in typically developing children and adolescents aged 10 and older. PMID:28611713

Acne vulgaris is known to impair many aspects of the quality of life (QoL) of its patients. To translate the Cardiff Acne Disability Index (CADI) from English into Hindi and to assess its validity and reliability in Hindi speaking patients with acne from India. Hindi version of CADI, translated and linguistically validated as per published international guidelines, along with a previously translated Hindi version of dermatology life quality index (DLQI) and a demographic questionnaire were administered to acne patients. The internal consistency reliability of the Hindi version of CADI and its concurrent validity were assessed by Cronbach's alpha co-efficient and Spearman's correlation co-efficient respectively. Construct validity was examined by factor analysis. Statistical analysis was carried out using the Statistical Package for the Social Sciences (SPSS) version 20 (SPSS Inc., Chicago, IL, USA) for Windows. One hundred Hindi speaking patients with various grades of acne participated in the study. Hindi version of CADI showed high internal consistency reliability (Cronbach's alpha co-efficient = 0.722). Mean item-to-total correlation co-efficient ranged from 0.502 to 0.760. Concurrent validity of the scale was supported by a significant correlation with the Hindi DLQI. Factor analysis revealed the presence of two dimensions underlying the factor structure of the scale. Hindi CADI is equivalent to the original English version and constitutes a reliable and valid tool for clinical assessment of the impact of acne on QoL.

The Strengths and Difficulties Questionnaire (SDQ) is validated for parents, but not yet for teachers in a broad age range of children. We conducted a cross-sectional study with 4-10 years old school children to investigate if the SDQ-T can be used instead of the validated but lengthy Teacher's Report Form (TRF) to acquire information about emotional and behavioral problems in the school community. Teachers of 453 children from primary schools were approached. Teachers of 394 children (response rate 86.9%) with a mean age of 7.1 years filled in the SDQ-T (n = 387), the TRF (n = 349) or both (n = 342). We assessed reliability by calculating internal consistency and concurrent validity (using correlation coefficients, sensitivity, specificity) of the SDQ-T compared with the TRF. Internal consistency of the SDQ-T Total Difficulties Score (SDQ-T TDS; Cronbach α = 0.80), hyperactivity/ inattention- (α = 0.86) and prosocial behavior (α = 0.81) was very good. Concurrent validity demonstrated a strong correlation of all subscales of the SDQ-T with the corresponding scale on the TRF (range 0.54-0.73), except for peer problems (0.46). Using a SDQ-T TDS cut-off score > 14, the SDQ-T had a good sensitivity (90%) and specificity (94%). The good reliability, validity and brevity of the SDQ-T make it an easily applicable questionnaire for obtaining information about emotional and behavioral problems from teachers in primary school children.

The clinical relevance of resilience has received considerable attention in recent years. The aim of this study is to demonstrate the reliability and validity of the Japanese version of the Resilience Scale (RS) and short version of the RS (RS-14). The original English version of RS was translated to Japanese and the Japanese version was confirmed by back-translation. Participants were 430 nursing and university psychology students. The RS, Center for Epidemiologic Studies Depression Scale (CES-D), Rosenberg Self-Esteem Scale (RSES), Social Support Questionnaire (SSQ), Perceived Stress Scale (PSS), and Sheehan Disability Scale (SDS) were administered. Internal consistency, convergent validity and factor loadings were assessed at initial assessment. Test-retest reliability was assessed using data collected from 107 students at 3 months after baseline. Mean score on the RS was 111.19. Cronbach's alpha coefficients for the RS and RS-14 were 0.90 and 0.88, respectively. The test-retest correlation coefficients for the RS and RS-14 were 0.83 and 0.84, respectively. Both the RS and RS-14 were negatively correlated with the CES-D and SDS, and positively correlated with the RSES, SSQ and PSS (all p < 0.05), although the correlation between the RS and CES-D was somewhat lower than that in previous studies. Factor analyses indicated a one-factor solution for RS-14, but as for RS, the result was not consistent with previous studies. This study demonstrates that the Japanese version of RS has psychometric properties with high degrees of internal consistency, high test-retest reliability, and relatively low concurrent validity. RS-14 was equivalent to the RS in internal consistency, test-retest reliability, and concurrent validity. Low scores on the RS, a positive correlation between the RS and perceived stress, and a relatively low correlation between the RS and depressive symptoms in this study suggest that validity of the Japanese version of the RS might be relatively low compared with the original English version.

The pediatric quality of life (QoL) questionnaire, the child-rated Kid-KINDL, has wording effects. However, no studies have examined for its parallel questionnaire, the parent-proxy Kid-KINDL. This study aimed to examine the psychometric properties and wording effects of the parent-proxy Kid-KINDL. Parents with 8- to 12-year-old children (n = 247) completed the parent-proxy Kid-KINDL, 83 of them completed it again 7-14 days later, and 241 of their children completed the child-rated Kid-KINDL. Internal consistency was examined using Cronbach's α; test-retest reliability and concurrent validity, using Pearson correlation coefficients (r); construct validity and wording effects, using confirmatory factor analyses (CFAs). The internal consistency of the parent-proxy Kid-KINDL total score was acceptable (α = .86). Test-retest reliability (r = .33-.60) and concurrent validity (r = .27-.42) were acceptable or nearly acceptable for all subscales and the total score. The CFA models simultaneously accounting for QoL traits and wording effects had satisfactory fit indices, and outperformed the model accounting only for QoL traits. However, four subscales had unsatisfactory internal consistency, which might be attributable to wording effects. When children are unable to complete a QoL questionnaire, the parent-proxy Kid-KINDL can substitute with all due cautions to wording effects and inconsistent reliability among different raters.

Objective This study was designed to investigate the revised and short version of the smartphone addiction scale and the proof of its validity in adolescents. In addition, it suggested cutting off the values by gender in order to determine smartphone addiction and elaborate the characteristics of smartphone usage in adolescents. Method A set of questionnaires were provided to a total of 540 selected participants from April to May of 2013. The participants consisted of 343 boys and 197 girls, and their average age was 14.5 years old. The content validity was performed on a selection of shortened items, while an internal-consistency test was conducted for the verification of its reliability. The concurrent validity was confirmed using SAS, SAPS and KS-scale. Receiver operating characteristics analysis was conducted to suggest cut-off. Results The 10 final questions were selected using content validity. The internal consistency and concurrent validity of SAS were verified with a Cronbach's alpha of 0.911. The SAS-SV was significantly correlated with the SAS, SAPS and KS-scale. The SAS-SV scores of gender (p<.001) and self-evaluation of smartphone addiction (p<.001) showed significant difference. The ROC analysis results showed an area under a curve (AUC) value of 0.963(0.888–1.000), a cut-off value of 31, sensitivity value of 0.867 and specificity value of 0.893 in boys while an AUC value of 0.947(0.887–1.000), a cut-off value of 33, sensitivity value of 0.875, and a specificity value of 0.886 in girls. Conclusions The SAS-SV showed good reliability and validity for the assessment of smartphone addiction. The smartphone addiction scale short version, which was developed and validated in this study, could be used efficiently for the evaluation of smartphone addiction in community and research areas.

Facial lines or wrinkles are among the most visible signs of aging, and minimally invasive cosmetic procedures are becoming increasingly popular. The aim of this study was to develop and validate the Facial Line Satisfaction Questionnaire (FLSQ) for use in adults with upper facial lines (UFL). A literature review, concept elicitation interviews (n = 33), and cognitive debriefing interviews (n = 23) of adults with UFL were conducted to develop the FLSQ. The FLSQ comprises Baseline and Follow-up versions and was field-tested with 150 subjects in a US observational study designed to assess its psychometric performance. Analyses included acceptability (item and scale distribution [i.e. missingness, floor, and ceiling effects]), reliability, and validity (including concurrent validity). In total, 69 concepts were elicited during patient interviews. Following cognitive debriefing interviews, the FLSQ-Baseline version included 11 items and the Follow-up version included 13 items. Response rates for the FLSQ were 100% and 73% at baseline and follow-up, respectively; no items had excessive missing data. Questionnaire scale scores were normally distributed. Most domain scores demonstrated good internal consistency reliability (Cronbach's α ≥ 0.70). Most items within their respective domains exhibited good convergent (item-scale correlations > 0.40) and discriminant (items had higher correlation with their hypothesized scales than other scales) validity. Concurrent validity correlation coefficients of the FLSQ domain scores with the associated concurrent measures were acceptable (range: r = 0.40-0.70). Six FLSQ items demonstrated reliability and validity as stand-alone items outside their domains. The FLSQ is a valid questionnaire for assessing treatment expectations, satisfaction, impact, and preference in adults with UFL. © 2015 The Authors.

Objectives. The Evaluation of Daily Activity Questionnaire (EDAQ) includes 138 items in 14 domains identified as important by people with RA. The aim of this study was to test the validity and reliability of the English EDAQ. Methods. A total of 502 participants completed two questionnaires 3 weeks apart. The first consisted of the EDAQ, HAQ, RA Quality of Life (RAQoL) and the Medical Outcomes Scale (MOS) 36-item Short-Form Health Survey (SF-36v2), and the second consisted of the EDAQ only. The 14 EDAQ domains were tested for: unidimensionality—using confirmatory factor analysis; fit, response dependency, invariance across groups (differential item functioning)—using Rasch analysis; internal consistency [Person Separation Index (PSI)]; concurrent validity—by correlations with the HAQ, SF-36v2 and RAQoL; and test–retest reliability (Spearman’s correlations). Results. Confirmatory factor analysis of the 14 EDAQ domains indicated unidimensionality, after adjustment for local dependency in each domain. All domains achieved a root mean square error of approximation <0.10 and satisfied Rasch model expectations for local dependency. DIF by age, gender and employment status was largely absent. The PSI was consistent with individual use (PSI = 0.94 for all 14 domains). For all domains, except Caring, concurrent validity was good: HAQ (rs = 0.72–0.91), RAQoL (rs = 0.67–0.82) and SF36v2 Physical Function scale (rs = −0.60 to −0.84) and test–retest reliability was good (rs = 0.70–0.89). Conclusion. Analysis supported a 14-domain, two-component structure (Self care and Mobility) of the EDAQ, where each domain, and both components, satisfied Rasch model requirements, and have robust reliability and validity.

ABSTRACT Purpose: To investigate the concurrent validity of the Saskatoon Falls Prevention Consortium's Falls Screening and Referral Algorithm (FSRA). Method: A total of 29 older adults (mean age 77.7 [SD 4.0] y) residing in an independent-living senior's complex who met inclusion criteria completed a demographic questionnaire and the components of the FSRA and Berg Balance Scale (BBS). The FSRA consists of the Elderly Fall Screening Test (EFST) and the Multi-factor Falls Questionnaire (MFQ); it is designed to categorize individuals into low, moderate, or high fall-risk categories to determine appropriate management pathways. A predictive model for probability of fall risk, based on previous research, was used to determine concurrent validity of the FSRI. Results: The FSRA placed 79% of participants into the low-risk category, whereas the predictive model found the probability of fall risk to range from 0.04 to 0.74, with a mean of 0.35 (SD 0.25). No statistically significant correlation was found between the FSRA and the predictive model for probability of fall risk (Spearman's ρ=0.35, p=0.06). Conclusion: The FSRA lacks concurrent validity relative to to a previously established model of fall risk and appears to over-categorize individuals into the low-risk group. Further research on the FSRA as an adequate tool to screen community-dwelling older adults for fall risk is recommended. PMID:24381379

Young men who have been involved with the criminal justice system are more likely to have concurrent sexual partners, a key driver of sexually transmitted infections. The value men place on having sexual relationships to validate themselves may play an important role in understanding this association. Data were from a household survey. Young men (N = 132), aged 16 to 24 years, self-reported whether they ever spent time in jail or juvenile detention and if they had sexual partnerships that overlapped in time. A novel scale, "Validation through Sex and Sexual Relationships" (VTSSR) assessed the importance young men place on sex and sexual relationships (α = 0.91). Weighted logistic regression accounted for the sampling design. The mean (SD) VTSSR score was 23.7 (8.8) with no differences by race. Both criminal justice involvement (CJI) (odds ratio [OR], 3.69; 95% confidence interval [CI], 1.12-12.1) and sexual validation (OR, 1.10; 95% CI, 1.04-1.16) were associated with an increased odds of concurrency; however, CJI did not remain associated with concurrency in the fully adjusted model. There was effect modification, CJI was associated with concurrency among those who scored high on sexual validation (OR, 9.18; 95% CI, 1.73-48.6]; however, there was no association among those who scored low on sexual validation. Racial differences were observed between CJI and concurrency, but not between sexual validation and concurrency. Sexual validation may be an important driver of concurrency for men who have been involved with the criminal justice system. Study findings have important implications on how sexual validation may explain racial differences in rates of concurrency.

In this study the reliability and validity of the Korean version of the Cancer Stigma Scale (KCSS) was evaluated. The KCSS was formed through translation and modification of Cataldo Lung Cancer Stigma Scale. The KCSS, Psychological Symptom Inventory (PSI), and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ-C30) were administered to 247 men and women diagnosed with one of the five major cancers. Construct validity, item convergent and discriminant validity, concurrent validity, known-group validity, and internal consistency reliability of the KCSS were evaluated. Exploratory factor analysis supported the construct validity with a six-factor solution; that explained 65.7% of the total variance. The six-factor model was validated by confirmatory factor analysis (Q (χ²/df)= 2.28, GFI=.84, AGFI=.81, NFI=.80, TLI=.86, RMR=.03, and RMSEA=.07). Concurrent validity was demonstrated with the QLQ-C30 (global: r=-.44; functional: r=-.19; symptom: r=.42). The KCSS had known-group validity. Cronbach's alpha coefficient for the 24 items was .89. The results of this study suggest that the 24-item KCSS has relatively acceptable reliability and validity and can be used in clinical research to assess cancer stigma and its impacts on health-related quality of life in Korean cancer patients. © 2017 Korean Society of Nursing Science

To assess the potential of the LEAP™ infrared motion tracking device to map laparoscopic instrument movement in a simulated environment. Simulator training is optimized when augmented by objective performance feedback. We explore the potential LEAP has to provide this in a way compatible with affordable take-home simulators. LEAP and the previously validated InsTrac visual tracking tool mapped expert and novice performances of a standardized simulated laparoscopic task. Ability to distinguish between the 2 groups (construct validity) and correlation between techniques (concurrent validity) were the primary outcome measures. Forty-three expert and 38 novice performances demonstrated significant differences in LEAP-derived metrics for instrument path distance (P < .001), speed (P = .002), acceleration (P < .001), motion smoothness (P < .001), and distance between the instruments (P = .019). Only instrument path distance demonstrated a correlation between LEAP and InsTrac tracking methods (novices: r = .663, P < .001; experts: r = .536, P < .001). Consistency of LEAP tracking was poor (average % time hands not tracked: 31.9%). The LEAP motion device is able to track the movement of hands using instruments in a laparoscopic box simulator. Construct validity is demonstrated by its ability to distinguish novice from expert performances. Only time and instrument path distance demonstrated concurrent validity with an existing tracking method however. A number of limitations to the tracking method used by LEAP have been identified. These need to be addressed before it can be considered an alternative to visual tracking for the delivery of objective performance metrics in take-home laparoscopic simulators. © The Author(s) 2015.

Objective Modify the existing 45-item velopharyngeal insufficiency (VPI) quality of life (QOL) instrument (VPIQL), assess the modified instrument for reliability and provide further validation. There are patient and parent versions of the instrument. Design Validation convenience sample from a previously conducted pilot study. Setting Two academic tertiary referral medical centers. Participants De-identified data were used from 29 subjects with VPI and 29 control subjects age 5–17 years, and parents. Outcome measures Subjects and parents completed VPIQL and a generic pediatric QOL instrument (PedsQL4-0). Data Analysis Twenty-two items were removed from the VPIQL for ceiling effects, floor effects, and redundancy, to produce the modified instrument, VPI Effects on Life Outcomes (VELO) instrument. VELO was tested for internal consistency (Chronbach’s alpha), discriminant validity (paired t-test with control subjects), and concurrent validity (Pearson correlation with the PedsQL4-0). These analyses were also completed for parents. Results The 45-item VPIQL instrument was reduced to the 23-item VELO instrument. The VELO had excellent internal consistency (Chronbach’s alpha 0.96 for parents and 0.95 for VPI subjects). The VELO discriminated well between VPI and control subjects, with mean score (SD) was significantly lower (worse) for VPI subjects (67.6 [23.9]) than for control subjects (97.0 [5.2]) (p<0.0001). The VELO total score was significantly correlated with the PedsQL4.0 (r=0.73) among subjects with VPI. Similar results were seen in parent responses. Conclusions The VELO is a 23-item QOL instrument that was designed to measure and follow QOL in subjects with VPI, with less burden than the original VPIQL. VELO demonstrates internal consistency, disciminant validty, and concurrent validity with the PedsQL4-0. PMID:23069823

Employee engagement is a fundamental component of quality healthcare. In order to provide empirical data of engagement in NHS Scotland an Employee Engagement Index was co-constructed with staff. 'iMatter' consists of 25 Likert questions developed iteratively from the literature and a series of validation events with NHS Scotland staff. The aim of this study was to test the face, content and construct validity of iMatter. Cross sectional survey of NHS Scotland staff. In January 2013 iMatter was sent to 2300 staff across all disciplines in NHS Scotland. 1280 staff completed it. Demographic data were collected. Internal consistency of the scale was calculated. Construct validity consisted of concurrent application of factor analysis and Rasch analysis. Face and content validity were checked using 3 focus groups. The sample was representative of the NHSScotland population. iMatter showed very strong reliability (α = 0.958). Factor analysis revealed a four-factor structure consistent with the following interpretation: iMatter showed evidence of high reliability and validity. It is a popular measure of staff engagement in NHS Scotland. Implications for practice focus on the importance of coproduction in psychometric development.

Abstract Objective To evaluate the reliability and validity of the newly developed Physician Enabling Skills Questionnaire (PESQ) by assessing its internal consistency, test-retest reliability, concurrent validity with patient-centred care, and predictive validity with patient activation and patient enablement. Design Validation study. Setting Saguenay, Que. Participants One hundred patients with at least 1 chronic disease who presented in a waiting room of a regional health centre family medicine unit. Main outcome measures Family physicians’ enabling skills, measured with the PESQ at 2 points in time (ie, while in the waiting room at the family medicine unit and 2 weeks later through a mail survey); patient-centred care, assessed with the Patient Perception of Patient-Centredness instrument; patient activation, assessed with the Patient Activation Measure; and patient enablement, assessed with the Patient Enablement Instrument. Results The internal consistency of the 6 subscales of the PESQ was adequate (Cronbach α = .69 to .92). The test-retest reliability was very good (r = 0.90; 95% CI 0.84 to 0.93). Concurrent validity with the Patient Perception of Patient-Centredness instrument was good (r = −0.67; 95% CI −0.78 to −0.53; P < .001). The PESQ accounts for 11% of the total variance with the Patient Activation Measure (r2 = 0.11; P = .002) and 19% of the variance with the Patient Enablement Instrument (r2 = 0.19; P < .001). Conclusion The newly developed PESQ presents good psychometric properties, allowing for its use in practice and research. PMID:26889507

Objective: The Trait Meta-Mood Scale (TMMS), a 30-item self-assessment questionnaire, has been developed to measure perceived emotional intelligence (EI) level in 3 dimensions: Attention, Clarity and Repair. This study aimed to explore the psychometric properties of the French version of this instrument. Method: The instrument factor structure, normality, internal consistency, stability and concurrent validity were assessed in a sample of 824 young adults (456 female). Besides TMMS, participants completed self-assessment questionnaires for affectivity (Shortened Beck Depression Inventory, State and Trait Anxiety Inventory, Positive and Negative emotion scale), alexithymia (Bermond-Vorst Alexithymia Questionnaire-B) and interpersonal functioning (Empathy Quotient). Discriminant validity was tested in 64 female patients with anorexia nervosa, identified in literature as having difficulties with introspection, expression and emotional regulation. Results: Confirmatory factor analysis results replicate the 3-factor structure. Internal consistency and reliability indices are adequate. Direction and degree of correlation coefficients between TMMS dimensions and other questionnaires support the instrument concurrent validity. TMMS allows to highlight differences in perceived EI levels between men and women (Attention: p < 0.001 ; Clarity: p < 0.05) as well as between patients with anorexia nervosa and control subjects (p < 0.001 for all 3 dimensions). Conclusion: This first validation study shows satisfying psychometric properties for TMMS French version. PMID:27310229

To validate the initial psychometric properties of a Healthcare Needs Scale for Youth with Congenital Heart Disease. As the number of patients with congenital heart disease surviving to adulthood increases, the transitional healthcare needs for adolescents and young adults with congenital heart disease require investigation. However, few tools comprehensively identify the healthcare needs of youth with congenital heart disease. A cross-sectional study was employed to examine the psychometric properties of the Healthcare Needs Scale for Youth with Congenital Heart Disease. The sample consisted of 500 patients with congenital heart disease, aged 15-24 years, from paediatric cardiology departments and covered the period from March-August 2015. The patients completed the 25-item Healthcare Needs Scale for Youth with Congenital Heart Disease, the questionnaire on health needs for adolescents and the WHO Quality of Life-BREF. Reliability and construct, concurrent, predictive and known-group validity were examined. The Healthcare Needs Scale for Youth with Congenital Heart Disease includes three dimensions, namely health management, health policy and individual and interpersonal relationships, which consist of 25 items. It demonstrated excellent internal consistency and sound construct, concurrent, predictive and known-group validity. The Healthcare Needs Scale for Youth with Congenital Heart Disease is a psychometrically robust measure of the healthcare needs of youth with congenital heart disease. It has the potential to provide nurses with a means to assess and identify the concerns of youth with congenital heart disease and to help them achieve a successful transition to adult care. © 2017 John Wiley & Sons Ltd.

Physical therapy for youth with cerebral palsy (CP) who are ambulatory includes interventions to increase functional mobility and participation in physical activity (PA). Thus, reliable and valid measures are needed to document PA in youth with CP. The purpose of this study was to evaluate the inter-instrument reliability and concurrent validity of 3 accelerometer-based motion sensors with indirect calorimetry as the criterion for measuring PA intensity in youth with CP. Fifty-seven youth with CP (mean age=12.5 years, SD=3.3; 51% female; 49.1% with spastic hemiplegia) participated. Inclusion criteria were: aged 6 to 20 years, ambulatory, Gross Motor Function Classification System (GMFCS) levels I through III, able to follow directions, and able to complete the full PA protocol. Protocol activities included standardized activity trials with increasing PA intensity (resting, writing, household chores, active video games, and walking at 3 self-selected speeds), as measured by weight-relative oxygen uptake (in mL/kg/min). During each trial, participants wore bilateral accelerometers on the upper arms, waist/hip, and ankle and a portable indirect calorimeter. Intraclass coefficient correlations (ICCs) were calculated to evaluate inter-instrument reliability (left-to-right accelerometer placement). Spearman correlations were used to examine concurrent validity between accelerometer output (activity and step counts) and indirect calorimetry. Friedman analyses of variance with post hoc pair-wise analyses were conducted to examine the validity of accelerometers to discriminate PA intensity across activity trials. All accelerometers exhibited excellent inter-instrument reliability (ICC=.94-.99) and good concurrent validity (rho=.70-.85). All accelerometers discriminated PA intensity across most activity trials. This PA protocol consisted of controlled activity trials. Accelerometers provide valid and reliable measures of PA intensity among youth with CP. © 2016 American Physical Therapy Association.

Introduction The Clinical Opiate Withdrawal Scale (COWS) is an 11-item clinician-administered scale assessing opioid withdrawal. Though commonly used in clinical practice, it has not been systematically validated. The present study validated the COWS in comparison to the validated Clinical Institute Narcotic Assessment (CINA) scale. Method Opioid-dependent volunteers were enrolled in a residential trial and stabilized on morphine 30 mg given subcutaneously four times daily. Subjects then underwent double-blind, randomized challenges of intramuscularly administered placebo and naloxone (0.4 mg) on separate days, during which the COWS, CINA, and visual analog scale (VAS) assessments were concurrently obtained. Subjects completing both challenges were included (N=46). Correlations between mean peak COWS and CINA scores as well as self-report VAS questions were calculated. Results Mean peak COWS and CINA scores of 7.6 and 24.4, respectively, occurred on average 30 minutes post-injection of naloxone. Mean COWS and CINA scores 30 minutes after placebo injection were 1.3 and 18.9, respectively. The Pearson correlation coefficient for peak COWS and CINA scores during the naloxone challenge session was 0.85 (p<0.001). Peak COWS scores also correlated well with peak VAS self-report scores of bad drug effect (r=0.57, p<0.001) and feeling sick (r=0.57, p<0.001), providing additional evidence of concurrent validity. Placebo was not associated with any significant elevation of COWS, CINA, or VAS scores, indicating discriminant validity. Cronbach’s alpha for the COWS was 0.78, indicating good internal consistency (reliability). Discussion COWS, CINA, and certain VAS items are all valid measurement tools for acute opiate withdrawal.

The multiple choice procedure (MCP) is used to assess the relative reinforcing value of concurrently available stimuli. The MCP was originally developed to assess the reinforcing value of drugs; the current within-subjects study employed the MCP to assess the reinforcing value of gambling behavior. Participants (N = 323) completed six versions of the MCP that presented hypothetical choices between money to be used while gambling ($10 or $25) versus escalating amounts of guaranteed money available immediately or after delays of either 1 week or 1 month. Results suggest that choices on the MCP are correlated with other measures of gambling behavior, thus providing concurrent validity data for using the MCP to quantify the relative reinforcing value of gambling. The MCP for gambling also displayed sensitivity to reinforcer magnitude and delay effects, which provides evidence of criterion validity. The results are consistent with a behavioral economic model of addiction and suggest that the MCP could be a valid tool for future research on gambling behavior.

The Body Image Disturbance Questionnaire-Scoliosis (BIDQ-S) is a seven-item questionnaire inquiring into patients' worries about back shape and associated problems at school, at work, with friends or family, and whether the patients are avoiding certain activities. The aim of this study was to translate the BIDQ-S into German (G-BIDQ-S), test its reliability, and establish its convergent, divergent, concurrent, and discriminant validity. In a prospective cohort study, 259 patients with idiopathic scoliosis (mean age 30.2; 221 female; mean Cobb angle 43.8°) completed the G-BIDQ-S; Scoliosis Research Society 22-r (SRS 22-r); Patient Health Questionnaire (PHQ-9); Positive and Negative Affect Schedule (PANAS); Questionnaire on Body Dysmorphic Symptoms (FKS); and WHO-5 Well-Being Index. Healthy control individuals matched by age, sex and BMI (n = 149; mean age 36.1; 133 female; BMI = 23.0) answered the same questions to establish discriminant validity. Discriminant statistics, and Pearson and Spearman correlations were calculated. The G-BIDQ-S proved to be one-factorial, internally consistent (Cronbach alpha = 0.87), and stable over time (total score 2.22 vs. 2.21 during retest; retest reliability r = 0.79, P < 0.001). It correlated significantly with the mean SRS 22-r (r = -0.72, P < 0.001) and with Cobb angles (r = 0.30, P < 0.001)-convergent validity; much less with body mass index (r = 0.19, P < 0.001)-divergent validity; and with the PANAS (r = 0.55, P < 0.001), PHQ-9 (r = 0.53, P < 0.001), FKS (r = 0.67, P < 0.001), and WHO-5 (r = -0.54, P < 0.001)-concurrent validity. The G-BIDQ-S also showed discriminant validity, with a strong difference between the scoliosis group (total score 2.19) and the control group (total score 1.13; P < 0.001). The G-BIDQ-S showed good internal consistency, reliability, and convergent, divergent, concurrent, and discriminant validity. This questionnaire is the first one inquiring into patients' body image disturbances that has been validated and is available in German.

Introduction The Strengths and Difficulties Questionnaire (SDQ) is validated for parents, but not yet for teachers in a broad age range of children. We conducted a cross-sectional study with 4–10 years old school children to investigate if the SDQ-T can be used instead of the validated but lengthy Teacher’s Report Form (TRF) to acquire information about emotional and behavioral problems in the school community. Methods Teachers of 453 children from primary schools were approached. Teachers of 394 children (response rate 86.9%) with a mean age of 7.1 years filled in the SDQ-T (n = 387), the TRF (n = 349) or both (n = 342). We assessed reliability by calculating internal consistency and concurrent validity (using correlation coefficients, sensitivity, specificity) of the SDQ-T compared with the TRF. Results Internal consistency of the SDQ-T Total Difficulties Score (SDQ-T TDS; Cronbach α = 0.80), hyperactivity/ inattention- (α = 0.86) and prosocial behavior (α = 0.81) was very good. Concurrent validity demonstrated a strong correlation of all subscales of the SDQ-T with the corresponding scale on the TRF (range 0.54–0.73), except for peer problems (0.46). Using a SDQ-T TDS cut-off score > 14, the SDQ-T had a good sensitivity (90%) and specificity (94%). Discussion The good reliability, validity and brevity of the SDQ-T make it an easily applicable questionnaire for obtaining information about emotional and behavioral problems from teachers in primary school children.

Research shows that dysfunctional sleep-related cognitions play an important role in the development, maintenance and exacerbation of insomnia. This study examines the factorial validity, psychometric properties and both concurrent and predictive validity of the German version of the 16-item DBAS (dysfunctional beliefs and attitudes about sleep) scale. Data was collected in 864 vocational students from the German-speaking part of Switzerland (43% females, M age  = 17.9 years). Data collection took place twice within a 10-month interval. The students completed a German translation of the DBAS-16, the Insomnia Severity Index (ISI), the Pittsburgh Sleep Quality Index (PSQI), and provided information about their psychological functioning. Descriptive statistics, factorial validity, internal consistency, gender differences, concurrent, and predictive validity were examined. Confirmatory factor analysis supported the 4-factor structure of the DBAS-16. All factors (consequences, worry/helplessness, expectations, medication) were positively correlated and had acceptable psychometric properties. Females reported higher scores across all DBAS measures. Weak-to-moderate correlations were found between dysfunctional sleep-related beliefs, insomnia and poor sleep quality. Dysfunctional sleep-related beliefs were also associated with decreased psychological functioning, and consistently predicted insomnia and poor psychological functioning at follow-up, even after controlling for socio-demographic background and baseline levels. The present study provides support for the validity and psychometric properties of the German version of the DBAS-16. Most importantly, it corroborates the relevance of cognitive-emotional factors in the onset and maintenance of insomnia and psychological symptoms among young people.

The Obsessive-Compulsive Drinking Scale (OCDS) is a self-rating questionnaire that measures cognitive and behavioral aspects of craving for alcohol. The OCDS consists of two subscales: the obsessive thoughts of drinking subscale (OS) and the compulsive drinking subscale (CS). This study aims to validate the Japanese version of the OCDS. First, internal consistency and discriminant validity were evaluated. Second, a prospective longitudinal 3-month outcome study of 67 patients with alcohol dependence who participated in a relapse prevention program was designed to assess the concurrent and predictive validity of the OCDS. The OCDS demonstrated high internal consistency. The OS had high discriminant validity, while the CS did not. Twenty-three patients (34.3%) dropped out of treatment. These patients had significantly higher OS scores than those who completed the program. At 3 months, the relapse group had significantly higher OCDS scores than the no relapse group. Also, the OCDS score was higher in subjects who had early-onset alcohol dependence than late-onset dependence. The OCDS is useful for evaluating cognitive aspect of craving and predicts dropout and relapse.

To investigate the clinical potential of the Depression, Anxiety and Stress Scales (DASS 42) and its shorter version (DASS 21) for assessing emotional status following acquired brain injury. Participants included 23 individuals with traumatic brain injury (TBI), 25 individuals with brain tumour and 29 non-clinical controls. Investigations of internal consistency, test-re-test reliability, theory-consistent differences, sensitivity to change and concurrent validity were conducted. Internal consistency of the DASS was generally acceptable (r > 0.70), with the exception of the anxiety scale for the TBI sample. Test-re-test reliability (1-3 weeks) was sound for the depression scale (r > 0.75) and significant but comparatively lower for other scales (r = 0.60-0.73, p < 0.01). Theory-consistent differences were only evident between the brain tumour sample and non-clinical control sample on the anxiety scale (p < 0.01). Sensitivity to change of the DASS in the context of hospital discharge was demonstrated for depression and stress (p < 0.01), but not for anxiety (p > 0.05). Concurrent validity with the Hospital Anxiety and Depression Scale was significant for all scales of the DASS (p < 0.05). While the results generally support the clinical application of the DASS following ABI, further research examining the factor structure of existing and modified versions of the DASS is recommended.

Current early screeners for psychosis-risk states have still to prove ability in identifying at-risk individuals. Among screeners, the 92-item Prodromal Questionnaire (PQ-92) is often used. We aimed to assess the validity of its Italian translation in a large Italian adolescent and young adult help-seeking sample. We included all individuals aged 12-36years seeking help at psychiatric mental health services in a large semirural Roman area (534,600 population) who accepted to participate. Participants completed the Italian version of the PQ-92 and were subsequently assessed with the Structured Interview of Prodromal/Psychosis-Risk Syndromes (SIPS). We examined diagnostic accuracy (sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios) and content, concurrent, and convergent validity between PQ-92 and SIPS using Cronbach's alpha, Cohen's kappa, and Spearman's rho, respectively. We tested the validity of adopted cut-offs through Receiver Operating Characteristic (ROC) curves plotted against SIPS diagnoses and the instrument's factor-structure through Principal Component Analysis. PQ-92 showed high internal consistency, acceptable diagnostic accuracy and concurrent validity, and excellent convergent validity. ROC analyses pointed to scores of 18 on the Positive subscale and 36 on the total PQ-92 as best cut-offs. The Scree-test identified a four-factor solution as fitting best. Psychometric properties of Italian PQ-92 were satisfactory. Optimal cut-offs were confirmed at ≥18 on the positive subscale, but at ≥36 on the total scale was able to identify more SIPS-positive cases. Copyright © 2017 Elsevier B.V. All rights reserved.

Vertical jump is one of the most prevalent acts performed in several sport activities. It is therefore important to ensure that the measurements of vertical jump height made as a part of research or athlete support work have adequate validity and reliability. The aim of this study was to evaluate concurrent validity and reliability of the Optojump photocell system (Microgate, Bolzano, Italy) with force plate measurements for estimating vertical jump height. Twenty subjects were asked to perform maximal squat jumps and countermovement jumps, and flight time-derived jump heights obtained by the force plate were compared with those provided by Optojump, to examine its concurrent (criterion-related) validity (study 1). Twenty other subjects completed the same jump series on 2 different occasions (separated by 1 week), and jump heights of session 1 were compared with session 2, to investigate test-retest reliability of the Optojump system (study 2). Intraclass correlation coefficients (ICCs) for validity were very high (0.997-0.998), even if a systematic difference was consistently observed between force plate and Optojump (-1.06 cm; p < 0.001). Test-retest reliability of the Optojump system was excellent, with ICCs ranging from 0.982 to 0.989, low coefficients of variation (2.7%), and low random errors (±2.81 cm). The Optojump photocell system demonstrated strong concurrent validity and excellent test-retest reliability for the estimation of vertical jump height. We propose the following equation that allows force plate and Optojump results to be used interchangeably: force plate jump height (cm) = 1.02 × Optojump jump height + 0.29. In conclusion, the use of Optojump photoelectric cells is legitimate for field-based assessments of vertical jump height.

Few comprehensive measures exist to assess contributors to childhood obesity within the home, specifically among low-income populations. The current study describes the modification and psychometric testing of the Comprehensive Home Environment Survey (CHES), an inclusive measure of the home food, physical activity, and media environment related to childhood obesity. The items were tested for content relevance by an expert panel and piloted in the priority population. The CHES was administered to low-income parents of children 5 to 17 years (N = 150), including a subsample of parents a second time and additional caregivers to establish test-retest and interrater reliabilities. Children older than 9 years (n = 95), as well as parents (N = 150) completed concurrent assessments of diet and physical activity behaviors (predictive validity). Analyses and item trimming resulted in 18 subscales and a total score, which displayed adequate internal consistency (α = .74-.92) and high test-retest reliability (r ≥ .73, ps < .01) and interrater reliability (r ≥ .42, ps < .01). The CHES score and a validated screener for the home environment were correlated (r = .37, p < .01; concurrent validity). CHES subscales were significantly correlated with behavioral measures (r = -.20-.55, p < .05; predictive validity). The CHES shows promise as a valid/reliable assessment of the home environment related to childhood obesity, including healthy diet and physical activity.

The purpose of this research was to assess an Italian version of the Physical Activity Questionnaire for Older Children (PAQ-C-It). Three separate studies were conducted, whereby testing general psychometric properties, construct validity, concurrent validity and the factor structure of the PAQ-C-It among general and clinical pediatric population. Study 1 (n = 1170) examined the psychometric properties, internal consistency, factor structure (exploratory factor analysis, EFA) and construct validity with enjoyment perception during physical activity. Study 2 (n = 59) reported on reliability, construct validity with enjoyment and BMI, and on cross-sectional concurrent validity with objectively measured MVPA (tri-axial accelerometry) over the span of seven consecutive days. Study 3 (n = 58) examined the PAQ-C-It reliability, construct validity with BMI and VO2max as the objective measurement among a population of children with congenital heart defects (CHD). In study 2 and 3, the factor structure of the PAQ-C-It was then re-examined with an EFA. The PAQ-C-It showed acceptable to good reliability (alpha .70 to .83). Results on construct validity showed moderate but significant association with enjoyment perception (r = .30 and .36), with BMI (r = -.30 and -.79 for CHD simple form), and with the VO2max (r = .55 for CHD simple form). Significant concurrent validity with the objectively measured MVPA was reported (rho = .30, p < .05). Findings of the EFA suggested a two-factor structure for the PAQ-C-It, with items 2, 3, and 4 contributing little to the total score. This study supports the PAQ-C-It as an appropriate instrument to assess the MVPA levels of Italian children, including children with simple forms of CHD. Support is given to the possible instrument effectiveness on a large international perspective in order to level out data gathering across the globe.

Working dog organisations, such as Guide Dogs, need to regularly assess the behaviour of the dogs they train. In this study we developed a questionnaire-style behaviour assessment completed by training supervisors of juvenile guide dogs aged 5, 8 and 12 months old (n = 1,401), and evaluated aspects of its reliability and validity. Specifically, internal reliability, temporal consistency, construct validity, predictive criterion validity (comparing against later training outcome) and concurrent criterion validity (comparing against a standardised behaviour test) were evaluated. Thirty-nine questions were sourced either from previously published literature or created to meet requirements identified via Guide Dogs staff surveys and staff feedback. Internal reliability analyses revealed seven reliable and interpretable trait scales named according to the questions within them as: Adaptability; Body Sensitivity; Distractibility; Excitability; General Anxiety; Trainability and Stair Anxiety. Intra-individual temporal consistency of the scale scores between 5–8, 8–12 and 5–12 months was high. All scales excepting Body Sensitivity showed some degree of concurrent criterion validity. Predictive criterion validity was supported for all seven scales, since associations were found with training outcome, at at-least one age. Thresholds of z-scores on the scales were identified that were able to distinguish later training outcome by identifying 8.4% of all dogs withdrawn for behaviour and 8.5% of all qualified dogs, with 84% and 85% specificity. The questionnaire assessment was reliable and could detect traits that are consistent within individuals over time, despite juvenile dogs undergoing development during the study period. By applying thresholds to scores produced from the questionnaire this assessment could prove to be a highly valuable decision-making tool for Guide Dogs. This is the first questionnaire-style assessment of juvenile dogs that has shown value in predicting the training outcome of individual working dogs. PMID:28614347

The purpose of the current study is to evaluate the validity and reliability of the revised Gibson Test of Cognitive Skills, a computer-based battery of tests measuring short-term memory, long-term memory, processing speed, logic and reasoning, visual processing, as well as auditory processing and word attack skills. This study included 2,737 participants aged 5-85 years. A series of studies was conducted to examine the validity and reliability using the test performance of the entire norming group and several subgroups. The evaluation of the technical properties of the test battery included content validation by subject matter experts, item analysis and coefficient alpha, test-retest reliability, split-half reliability, and analysis of concurrent validity with the Woodcock Johnson III Tests of Cognitive Abilities and Tests of Achievement. Results indicated strong sources of evidence of validity and reliability for the test, including internal consistency reliability coefficients ranging from 0.87 to 0.98, test-retest reliability coefficients ranging from 0.69 to 0.91, split-half reliability coefficients ranging from 0.87 to 0.91, and concurrent validity coefficients ranging from 0.53 to 0.93. The Gibson Test of Cognitive Skills-2 is a reliable and valid tool for assessing cognition in the general population across the lifespan.

Quality palliative care depends on a deep understanding of distress facing patients nearing death. Yet, many aspects of psychosocial, existential and spiritual distress are often overlooked. The aim of this study was to test a novel psychometric--the Patient Dignity Inventory (PDI)--designed to measure various sources of dignity-related distress among patients nearing the end of life. Using standard instrument development techniques, this study examined the face validity, internal consistency, test-retest reliability, factor structure and concurrent validity of the PDI. The 25-items of the PDI derive from a model of dignity in the terminally ill. To establish its basic psychometric properties, the PDI was administered to 253 patients receiving palliative care, along with other measures addressing issues identified within the Dignity Model in the Terminally Ill. Cronbach's coefficient alpha for the PDI was 0.93; the test-retest reliability was r = 0.85. Factor analysis resulted in a five-factor solution; factor labels include Symptom Distress, Existential Distress, Dependency, Peace of Mind, and Social Support, accounting for 58% of the overall variance. Evidence for concurrent validity was reported by way of significant associations between PDI factors and concurrent measures of distress. The PDI is a valid and reliable new instrument, which could assist clinicians to routinely detect end-of-life dignity-related distress. Identifying these sources of distress is a critical step toward understanding human suffering and should help clinicians deliver quality, dignity-conserving end-of-life care.

The Children's Dermatology Life Quality Index (CDLQI) evaluates the impact of skin diseases on the patient's quality of life. The purpose of the study was to translate and to validate the CDLQI into Serbian. The CDLQI was translated into Serbian following international recommendations for translation and cultural adaptation. The validation study was carried out on a large cohort of secondary schoolchildren who self-reported acne. Translating the CDLQI consisted of forward translation, reconciliation, back translation, back-translation review, and cognitive debriefing. The good internal consistency of the scale was demonstrated with a Cronbach alpha coefficient of 0.87. A Spearman correlation coefficient of 0.66 between the CDLQI and the Cardiff Acne Disability Index (CADI) was deemed satisfactory to demonstrate concurrent validity. The translation, cross-cultural adaptation, and psychometric qualities of the CDLQI were satisfactory, enabling its application in clinical practice and future studies.

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.

We determined the concurrent criterion validity of the Safe Driving Behavior Measure (SDBM) for on-road outcomes (passing or failing the on-road test as determined by a certified driving rehabilitation specialist) among older drivers and their family members-caregivers. On the basis of ratings from 168 older drivers and 168 family members-caregivers, we calculated receiver operating characteristic curves. The drivers' area under the curve (AUC) was .620 (95% confidence interval [CI] = .514-.725, p = .043). The family members-caregivers' AUC was .726 (95% CI = .622-.829, p ≤ .01). Older drivers' ratings showed statistically significant yet poor concurrent criterion validity, but family members-caregivers' ratings showed good concurrent criterion validity for the criterion on-road driving test. Continuing research with a more representative sample is being pursued to confirm the SDBM's concurrent criterion validity. This screening tool may be useful for generalist practitioners to use in making decisions regarding driving. Copyright © 2013 by the American Occupational Therapy Association, Inc.

Objective Motor imagery (MI) has been recently considered as an adjunct to physical rehabilitation in patients with multiple sclerosis (MS). It is necessary to assess MI abilities and benefits in patients with MS by using a reliable tool. The Kinesthetic and Visual Imagery Questionnaire (KVIQ) was recently developed to assess MI ability in patients with stroke and other disabilities. Considering the different underlying pathologies, the present study aimed to examine the validity and reliability of the KVIQ in MS patients. Method Fifteen MS patients were assessed using the KVIQ in 2 sessions (5-14days apart) by the same examiner. In the second session, the participants also completed a revised MI questionnaire (MIQ-R) as the gold standard. Intra-class correlation coefficients (ICCs) were measured to determine test-retest reliability. Spearman's correlation analysis was performed to assess concurrent validity with the MIQ-R. Furthermore, the internal consistency (Cronbach's alpha) and factorial structure of the KVIQ were studied. Results The test-retest reliability for the KVIQ was good (ICCs: total KVIQ=0.89, visual KVIQ=0.85, and kinesthetic KVIQ=0.93), and the concurrent validity between the KVIQ and MIQ-R was good (r=0.79). The KVIQ had good internal consistency, with high Cronbach's alpha (alpha=0.84). Factorial analysis showed the bi-factorial structure of the KVIQ, which was explained by visual=57.6% and kinesthetic=32.4%. Conclusions The results of the present study revealed that the KVIQ is a valid and reliable tool for assessing MI in MS patients. PMID:24271091

This research aimed to (a) develop a measure of prosocial and antisocial behavior in sport, (b) examine its invariance across sex and sport, and (c) provide evidence for its discriminant and concurrent validity. We conducted two studies. In study 1, team sport athletes (N=1,213) recruited from 103 teams completed questionnaires assessing demographics and prosocial and antisocial behaviors in sport. Factor analyses revealed two factors representing prosocial behavior and two factors representing antisocial behavior. The model had a very good fit to the data and showed configural, metric, and scalar invariance across sex and sport. The final scale consisted of 20 items. In Study 2, team-sport athletes (N=106) completed the scale and measures of empathy and goal orientation. Analyses provided support for the discriminant and concurrent validity of the scale. In conclusion, the new scale can be used to measure prosocial and antisocial behaviors in team sport.

Objectives: To test the psychometric properties of an adapted Arabic version of the state trait anxiety-form Y (STAI-Y) in Saudi adult dental patients. Methods: In this cross-sectional study, the published Arabic version of the STAI-Y was evaluated by 2 experienced bilingual professionals for its compatibility with Saudi culture and revised prior to testing. Three hundred and eighty-seven patients attending dental clinics for treatment at the Faculty of Dentistry Hospital, King Abdullah University, Jeddah, Kingdom of Saudi Arabia, participated in the study. The Arabic version of the modified dental anxiety scale (MDAS) and visual analogue scale (VAS) ratings of anxiety were used to assess the concurrent criterion validity. Results: The Arabic version of the STAI-Y had high internal consistency reliability (Cronbach’s alpha: 0.989) for state and trait subscales. Factor analysis indicated unidimensionality of the scale. Correlations between STAI-Y scores and both MDAS and VAS scores indicated strong concurrent criterion validity. Discriminant validity was supported by the findings that higher anxiety levels were present among females as opposed to males, younger individuals as compared to older individuals, and patients who do not visit the dentist unless they have a need as opposed to more frequent visitors to the dental office. Conclusion: The Arabic version of the STAI-Y has an adequate internal consistency reliability, generally similar to that reported in the international literature, suggesting it is appropriate for assessing dental anxiety in Arabic speaking populations.

To validate a body dissatisfaction scale for adolescents. The study included 386 female and male adolescents aged 10 to 17 years enrolled in a private elementary and middle school in the city of São Bernardo do Campo, southeastern Brazil, in 2006. 'Escala de Evaluación da Insatisfación Corporal para Adolescentes' (body dissatisfaction scale for adolescents) was translated and culturally adapted. The Portuguese instrument was evaluated for internal consistency using Cronbach's alpha, factor analysis with Varimax rotation, discriminant validity by comparing score means according to nutritional status (low weight, normal weight, and at risk of overweight and obesity) using the Kruskal-Wallis test. Concurrent validity was assessed using Spearman's rank correlation coefficient between scores and body mass index, waist-hip ratio and waist circumference. Reproducibility was evaluated using Wilcoxon test, and intraclass correlation coefficient. The translated and back-translated scale showed good agreement with the original one. The translated scale had good internal consistency in all subgroups studied (males and females in early and intermediate adolescence) and was able to discriminate adolescents according to their nutritional status. In the concurrent analysis, all three measures were correlated, except for males in early adolescence. Its reproducibility was ascertained. The 'Escala de Evaluación da Insatisfación Corporal para Adolescentes' was successfully translated into Portuguese and adapted to the Brazilian background and showed good results. It is recommended for the evaluation of the attitudinal component of body image in adolescents.

Interest in cosmetic surgery is increasing, with rhinoplasty being one of the most popular surgical procedures. It is essential that surgeons identify patients with existing psychological conditions before any procedure. This study aimed to develop and validate the Interest in Aesthetic Rhinoplasty Scale (IARS). Four studies were conducted to develop the IARS and to evaluate different indices of validity (face, content, construct, criterion, and concurrent validities) and reliability (internal consistency, split-half coefficient, and temporal stability) of the scale. The four study samples included a total of 463 participants. Statistical analysis revealed satisfactory psychometric properties in all samples. Scores on the IARS were negatively correlated with self-esteem scores ( r  = -0.296; p  < 0.01) and positively associated with scores for psychopathologic symptoms ( r  = 0.164; p  < 0.05), social dysfunction ( r  = 0.268; p  < 0.01), and depression ( r  = 0.308; p  < 0.01). The internal and test-retest coefficients of consistency were found to be high (α = 0.93; intraclass coefficient = 0.94). Rhinoplasty patients were found to have significantly higher IARS scores than nonpatients ( p  < 0.001). Findings of the present studies provided evidence for face, content, construct, criterion, and concurrent validities and internal and test-retest reliability of the IARS. This evidence supports the use of the scale in clinical and research settings. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

To report evidence for the concurrent validity and reliability of dynamic MRI techniques to evaluate in vivo joint and muscle mechanics, and to propose recommendations for their use in the assessment of normal and impaired musculoskeletal function. The search was conducted on articles published in Web of science, PubMed, Scopus, Academic search Premier, and Cochrane Library between 1990 and August 2017. Studies that reported the concurrent validity and/or reliability of dynamic MRI techniques for in vivo evaluation of joint or muscle mechanics were included after assessment by two independent reviewers. Selected articles were assessed using an adapted quality assessment tool and a data extraction process. Results for concurrent validity and reliability were categorized as poor, moderate, or excellent. Twenty articles fulfilled the inclusion criteria with a mean quality assessment score of 66% (±10.4%). Concurrent validity and/or reliability of eight dynamic MRI techniques were reported, with the knee being the most evaluated joint (seven studies). Moderate to excellent concurrent validity and reliability were reported for seven out of eight dynamic MRI techniques. Cine phase contrast and real-time MRI appeared to be the most valid and reliable techniques to evaluate joint motion, and spin tag for muscle motion. Dynamic MRI techniques are promising for the in vivo evaluation of musculoskeletal mechanics; however results should be evaluated with caution since validity and reliability have not been determined for all joints and muscles, nor for many pathological conditions.

After critical examination of several aspects relating to the evaluation of some dimensions of emotional intelligence through self-assessment tools, is described the procedure of construction and validation of an Index for its measurement, conceived only for the routine assessment of health promotion programs mental in schools that include among their objectives the improvement of emotional intelligence specifically "outcome-oriented". On the basis of the two most common international tools, are listed 27 items plus 6 of control, illustrated two Focus Group (FG) of students (face validity). The scale obtained by FG was administered to 300 students, and the results were submitted to factorial analysis (construct validity). It was also evaluated the internal consistency with Cronbach's Alpha and studied concurrent validity with the emotional quotient inventory, a scale of perceived self-efficacy and a stress test rating. From the analysis of FG all the original items were modified, deleted 4, and reduced the encoding system from 6 to 4 levels of Likert scale. Of the 23 items included in the analysis have emerged five factors (intra-psychic dimension, interpersonal, impulsivity, adaptive coping, sense of self-efficacy) for a total of 15 items. Very satisfactory were the results of the validation process of internal consistency (0.72) and the concurrent validity. The results are positive. It is obtained in fact the shortest routine assessment tool currently available in Italy which constitutes a real Index, for which compilation are required on average 3 minutes. Is emphasized the characteristic of an Index, and not of questionnaire or interview for clinical use, highlighting the only specific use for mental health promotion programs in schools.

2014-01-01

ABSTRACT Background: There is an absence of research on the newly evolved term “fluffy” which describes body image and personality features among women. Research on “fluffiness” among Caribbean peoples has been limited by the lack of valid and reliable measures of the concept. Objective: This project addresses this problem by exploring the internal consistency reliability and the concurrent and discriminant validity of the Attitudes toward Fluffy Women Scale (ATFW) using a mixture of past and present students from The University of the West Indies (UWI), Mona, and the University of Technology (UTech), Kingston. Method: Past or present students from The UWI, Mona, and UTech, Kingston, were recruited for the study through the use of convenience sampling. A total of 80 students (38 males, 47.5%; 42 females, 52.5%) participated in the study. Results: Overall, the ATFW was found to have an acceptable degree of internal consistency reliability (α = 0.90). The scale also had reasonably good concurrent validity as evidenced by moderate correlations with scores on the Attitudes Toward Obese Persons Scale (r = −0.42) and acceptable discriminant validity as demonstrated through low correlations with a Bogardus Social Distance Scale designed to assess prejudice toward people living with the human immunodeficiency virus [HIV] (r = 0.29). This pattern of scores suggests that the majority of the stable variance underlying the ATFW assesses the “fluffy” concept (17.6%) while a smaller degree of the variability (8%) measures a conceptually similar but distinct concept. Conclusion: The Attitudes toward Fluffy Women scale was found to be a reliable and valid scale for assessing the attitudes of young adults toward fluffy women. PMID:25803379

Cross-cultural adaptation and validation of the Physical Therapy Outpatient Satisfaction Survey in an Italian musculoskeletal population

PubMed Central

2013-01-01

Background Although patient satisfaction is a relevant outcome measure for health care providers, few satisfaction questionnaires have been generally available to physical therapists or have been validated in an Italian population for use in the outpatient setting. The aim of this study was to translate, culturally adapt, and validate the Italian version of the Physical Therapy Outpatient Satisfaction Survey (PTOPS). Methods The Italian version of the PTOPS (PTOPS-I) was developed through forward-backward translation, review, and field-testing a pre-final version. The reliability of the final questionnaire was measured by internal consistency and test-retest stability at 7 days. Factor analysis was also used to explore construct validity. Concurrent validity was measured by comparing PTOPS-I with a 5-point Likert-type scale measure assessing the Global Perceived Effect (GPE) of the treatment and with a Visual Analogue Scale (VAS). Results 354 outpatients completed the PTOPS-I, and 56 took the re-test. The internal consistency (Cronbach’s alpha) of the original domains (Enhancers, Detractors, Location, and Cost) was 0.758 for Enhancers, 0.847 for Detractors, 0.885 for Location, and 0.706 for Cost. The test-retest stability (Intra-class Correlation Coefficients) was 0.769 for Enhancers, 0.893 for Detractors, 0.862 for Location, and 0.862 for Cost. The factor analysis of the Italian version revealed a structure into four domains, named Depersonalization, Inaccessibility, Ambience, and Cost. Concurrent validity with GPE was significantly demonstrated for all domains except Inaccessibility. Irrelevant or non-significant correlations were observed with VAS. Conclusion The PTOPS-I showed good psychometric properties. Its use can be suggested for Italian-speaking outpatients who receive physical therapy. PMID:23560848

This study aimed to develop a reliable and valid measure of functional health literacy in a Japanese clinical setting. Test development consisted of three phases: generation of an item pool, consultation with experts to assess content validity, and comparison with external criteria (the Japanese Health Knowledge Test) to assess criterion validity. A trial version of the test was administered to 535 Japanese outpatients. Internal consistency reliability, calculated by Cronbach's alpha, was 0.81, and concurrent validity was moderate. Receiver Operating Characteristics and Item Response Theory were used to classify patients as having adequate, marginal, or inadequate functional health literacy. Both inadequate and marginal functional health literacy were associated with older age, lower income, lower educational attainment, and poor health knowledge. The time required to complete the test was 10-15 min. This test should enable health workers to better identify patients with inadequate health literacy. © 2013 Wiley Publishing Asia Pty Ltd.

Risk perception is a subjective assessment of the actual or potential threat to one's life or, more broadly, to one's psychological well-being. Given the various risks associated with later life, a valid and reliable integrative screening tool for assessing risk perception among the elderly is warranted. The study examined the psychometric properties and factor structure of a new integrative risk perception instrument, the Perceived Risk Scale. This eight-item measure refers to various risks simultaneously, including terror, health issues, traffic accidents, violence, and financial loss, and was developed specifically for older adults. An online survey was conducted with 306 participants aged 50 years and older. The scale was examined using exploratory factor analysis and concurrent validity testing. Factor analysis revealed a two-factor structure: later-life risks and terror risks A high percentage of explained variance, as well as internal consistency, was found for the entire scale and for both factors. Concurrent validity was supported by significant positive associations with participants' depression and negative correlations with their life satisfaction. These findings suggest that the Perceived Risk Scale is internally reliable, valid, and appropriate for evaluating risk perception in later life. The scale's potential applications are discussed. © The Author(s) 2016.

Purpose The purpose of this review is to systematically explore and summarise the validity and reliability of telerehabilitation (TR)-based physiotherapy assessment for musculoskeletal disorders. Method A comprehensive systematic literature review was conducted using a number of electronic databases: PubMed, EMBASE, PsycINFO, Cochrane Library and CINAHL, published between January 2000 and May 2015. The studies examined the validity, inter- and intra-rater reliabilities of TR-based physiotherapy assessment for musculoskeletal conditions were included. Two independent reviewers used the Quality Appraisal Tool for studies of diagnostic Reliability (QAREL) and the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool to assess the methodological quality of reliability and validity studies respectively. Results A total of 898 hits were achieved, of which 11 articles based on inclusion criteria were reviewed. Nine studies explored the concurrent validity, inter- and intra-rater reliabilities, while two studies examined only the concurrent validity. Reviewed studies were moderate to good in methodological quality. The physiotherapy assessments such as pain, swelling, range of motion, muscle strength, balance, gait and functional assessment demonstrated good concurrent validity. However, the reported concurrent validity of lumbar spine posture, special orthopaedic tests, neurodynamic tests and scar assessments ranged from low to moderate. Conclusion TR-based physiotherapy assessment was technically feasible with overall good concurrent validity and excellent reliability, except for lumbar spine posture, orthopaedic special tests, neurodynamic testa and scar assessment.

In this study, the validity of 5 tests of children's social-emotional cognition, defined as their encoding, memory, and interpretation of social information, was tested. Participants were 126 clinic-referred children between the ages of 5 and 17. All 5 tests were evaluated in terms of their (a) concurrent validity, (b) incremental validity, and (c) clinical usefulness in predicting social functioning. Tests included measures of nonverbal sensitivity, social language, and social problem solving. Criterion measures included parent and teacher report of social functioning. Analyses support the concurrent validity of all measures, and the incremental validity and clinical usefulness of tests of pragmatic language and problem solving.

Background Music is an integral part of life in youth, and although it has been acknowledged that musical behavior reflects broader psychosocial aspects of adolescent behavior, no measurement instruments have been specifically designed for assessing musical engagement as an indicator of adolescent wellbeing and/or symptomatology. This study was conducted in order to develop and validate a scale for assessing musical engagement as an indicator of proneness for depression in youth. Method Items were developed based on the literature and a prior grounded theory analysis and three surveys (N = 54, N = 187, N = 211) were conducted to select, refine, test, and validate the items. Scale structure was investigated through interitem correlations, exploratory and confirmatory factor analyses (EFA, CFA), and concurrent validity was tested with correlations to depression and wellbeing. Results The final Healthy-Unhealthy Music Scale (HUMS) consists of 13 items that are divided into Healthy and Unhealthy subscales. Cronbach's alpha coefficients were .78 for Healthy and .83 for Unhealthy. The concurrent validity of the HUMS was confirmed through correlations to wellbeing, happiness and school satisfaction on one hand and depression, rumination, and stress on the other. Conclusions The HUMS is as a promising instrument for screening musical engagement that is indicative of proneness for depression in youth. PMID:26726295

Objective Conduct a multiagent–multimethod analysis of the validity of a brief measure of deviant peer affiliations and social acceptance (PASA) in young adolescents. Peer relationships are critical to child and adolescent social and emotional development, but currently available measures are tedious and time consuming. The PASA consists of a youth, parent, and teacher report that can be collected longitudinally to study development and intervention effectiveness. Method This longitudinal study included 998 middle school students and their families. We collected the PASA and peer sociometrics data in Grade 7 and a multiagent–multimethod construct of deviant peer clustering in Grade 8. Results Confirmatory factor analyses of the multiagent–multimethod data revealed that the constructs of deviant peer affiliations and social acceptance and rejection were distinguishable as unique but correlated constructs within the PASA. Convergent, discriminant, concurrent, and predictive validity of the PASA was satisfactory, although the acceptance and rejection constructs were highly correlated and showed similar patterns of concurrent validity. Factor invariance was established for mother and for father reports. Conclusions Results suggest that the PASA is a valid and reliable measure of peer affiliation and of social acceptance among peers during the middle school years and provides a comprehensive yet brief assessment of peer affiliations and social acceptance.

2008-04-01

A reliable and valid instrument to assess neuromotor condition in infancy is a prerequisite for early detection of developmental motor disorders. We developed a video-based assessment of motor behaviour, the Infant Motor Profile (IMP), to evaluate motor abilities, movement variability, ability to select motor strategies, movement symmetry, and fluency. The IMP consists of 80 items and is applicable in children from 3 to 18 months. The present study aimed to test intra- and interobserver reliability and concurrent validity of the IMP with the Alberta Infant Motor Scale (AIMS) and Touwen neurological examination. The study group consisted of 40 low-risk term (median gestational age [GA] 40 wks, range 38-42 wks) and 40 high-risk preterm infants (median GA 29.6 wks, range 26-33 wks) with corrected ages 4 to 18 months (31 females, 49 males). Intra- and interobserver agreement of the IMP were satisfactory (Spearman's rho=0.9). Concurrent validity of IMP and AIMS was good (Spearman's rho=0.8, p<0.005). The IMP was able to differentiate between infants with normal neurological condition, simple minor neurological dysfunction (MND), complex MND, and abnormal neurological condition (p<0.005). This means that the IMP may be a promising tool to evaluate neurological integrity during infancy, a suggestion that needs confirmation by means of assessment of larger groups of infants with heterogeneous neurological conditions.

2012-04-01

The original Personal Growth Initiative Scale (PGIS; Robitschek, 1998) was unidimensional, despite theory identifying multiple components (e.g., cognition and behavior) of personal growth initiative (PGI). The present research developed a multidimensional measure of the complex process of PGI, while retaining the brief and psychometrically sound properties of the original scale. Study 1 focused on scale development, including theoretical derivation of items, assessing factor structure, reducing number of items, and refining the scale length using samples of college students. Study 2 consisted of confirmatory factor analysis with 3 independent samples of college students and community members. Lastly, Study 3 assessed test-retest reliability over 1-, 2-, 4-, and 6-week periods and tests of concurrent and discriminant validity using samples of college students. The final measure, the Personal Growth Initiative Scale-II (PGIS-II), includes 4 subscales: Readiness for Change, Planfulness, Using Resources, and Intentional Behavior. These studies provide exploratory and confirmatory evidence for the 4-factor structure, strong internal consistency for the subscales and overall score across samples, acceptable temporal stability at all assessed intervals, and concurrent and discriminant validity of the PGIS-II. Future directions for research and clinical practice are discussed.

Compulsive exercise is a prominent feature for the majority of patients with Anorexia Nervosa (AN), but there is a dearth of research evaluating assessment instruments. This study assessed the concurrent validity of the exercise items of the Eating Disorder Examination (EDE) and Eating Disorder Examination-Questionnaire (EDE-Q), with the Compulsive Exercise Test (CET) and other self-report exercise measures in patients with AN. We also aimed to perform validation of the CET in an adult clinical sample. The sample consisted of 78 adults with AN, recruited for the randomized controlled trial "Taking a LEAP forward in the treatment of anorexia nervosa." At baseline, participants completed the EDE, EDE-Q, CET, Reasons for Exercise Inventory (REI), Commitment to Exercise Scale (CES) and Exercise Beliefs Questionnaire (EBQ). Correlational and regression analyses were performed. EDE exercise days and exercise time per day were positively correlated with each other and with all CET subscales (except Lack of exercise enjoyment), CES mean, EBQ total and REI total. Exercise time per day was associated with a higher EDE global score. The CET demonstrated good concurrent validity with the CES, the REI and the EBQ. Of the self-reports, the CET explained the greatest variance in eating disorder psychopathology and demonstrated good to excellent reliability in this sample. The EDE and EDE-Q demonstrated good concurrent validity with the CET. Further research is required to evaluate the CET's factor structure in a large clinical sample. However, the CET has demonstrated strong clinical utility in adult patients with AN. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:533-541). © 2016 Wiley Periodicals, Inc.

Reliability and validity of the Wolfram Unified Rating Scale (WURS)

PubMed Central

2012-01-01

Background Wolfram syndrome (WFS) is a rare, neurodegenerative disease that typically presents with childhood onset insulin dependent diabetes mellitus, followed by optic atrophy, diabetes insipidus, deafness, and neurological and psychiatric dysfunction. There is no cure for the disease, but recent advances in research have improved understanding of the disease course. Measuring disease severity and progression with reliable and validated tools is a prerequisite for clinical trials of any new intervention for neurodegenerative conditions. To this end, we developed the Wolfram Unified Rating Scale (WURS) to measure the severity and individual variability of WFS symptoms. The aim of this study is to develop and test the reliability and validity of the Wolfram Unified Rating Scale (WURS). Methods A rating scale of disease severity in WFS was developed by modifying a standardized assessment for another neurodegenerative condition (Batten disease). WFS experts scored the representativeness of WURS items for the disease. The WURS was administered to 13 individuals with WFS (6-25 years of age). Motor, balance, mood and quality of life were also evaluated with standard instruments. Inter-rater reliability, internal consistency reliability, concurrent, predictive and content validity of the WURS were calculated. Results The WURS had high inter-rater reliability (ICCs>.93), moderate to high internal consistency reliability (Cronbach’s α = 0.78-0.91) and demonstrated good concurrent and predictive validity. There were significant correlations between the WURS Physical Assessment and motor and balance tests (rs>.67, p<.03), between the WURS Behavioral Scale and reports of mood and behavior (rs>.76, p<.04) and between WURS Total scores and quality of life (rs=-.86, p=.001). The WURS demonstrated acceptable content validity (Scale-Content Validity Index=0.83). Conclusions These preliminary findings demonstrate that the WURS has acceptable reliability and validity and captures individual differences in disease severity in children and young adults with WFS.

No disease-specific instruments exist in Dutch, French, Italian, and Swedish to measure health status in idiopathic pulmonary fibrosis (IPF) and other interstitial lung diseases (ILDs). The King's Brief Interstitial Lung Disease (K-BILD) is a 15-item validated questionnaire assessing health status in patients with ILD. The aim of this study was to translate and validate the K-BILD to French, Italian, Swedish, and Dutch versions. The K-BILD was translated following a forward-backward multistep procedure and tested in structured patient interviews. Subsequently, 195 outpatients with ILD were asked to complete K-BILD, St. George's Respiratory Questionnaire (SGRQ), and Euroqol EQ-5D-5L (EQ5D), twice, 2 weeks apart. Internal consistency, concurrent validity, and repeatability were determined. No major difficulties occurred in the translation processes. The K-BILD was considered comprehensible and relevant by patients. One hundred seventy-six patients (108 IPF and 68 other ILDs) completed the translated K-BILD. Internal consistency was good for all K-BILD modules (Cronbach's α 0.70-0.93). Concurrent validity of K-BILD was strong compared with SGRQ ( r = -0.86) and EQ5D ( r = 0.68), low with transfer capacity of the lung for carbon monoxide corrected for hemoglobin ( r = 0.33) and with forced vital capacity ( r = 0.35). The K-BILD and its domains were repeatable over 2 weeks; intraclass correlation coefficients were 0.86-0.93 ( n = 159). Known groups validity showed K-BILD was able to discriminate between patients based on severity of disease. K-BILD's validity and reliability for patients with IPF was similar to that of other ILDs. The French, Italian, Swedish, and Dutch translated K-BILD questionnaires were well-received by patients and demonstrated excellent validity comparable to the original English K-BILD.

Reliability and validity in a nutshell.

PubMed

Bannigan, Katrina; Watson, Roger

2009-12-01

To explore and explain the different concepts of reliability and validity as they are related to measurement instruments in social science and health care. There are different concepts contained in the terms reliability and validity and these are often explained poorly and there is often confusion between them. To develop some clarity about reliability and validity a conceptual framework was built based on the existing literature. The concepts of reliability, validity and utility are explored and explained. Reliability contains the concepts of internal consistency and stability and equivalence. Validity contains the concepts of content, face, criterion, concurrent, predictive, construct, convergent (and divergent), factorial and discriminant. In addition, for clinical practice and research, it is essential to establish the utility of a measurement instrument. To use measurement instruments appropriately in clinical practice, the extent to which they are reliable, valid and usable must be established.

2018-01-01

GALI or Global Activity Limitation Indicator is a global survey instrument measuring participation restriction. GALI is the measure underlying the European indicator Healthy Life Years (HLY). Gali has a substantial policy use within the EU and its Member States. The objective of current paper is to bring together what is known from published manuscripts on the validity and the reliability of GALI. Following the PRISMA guidelines, two search strategies (PUBMED, Google Scholar) were combined to identify manuscripts published in English with publication date 2000 or beyond. Articles were classified as reliability studies, concurrent or predictive validity studies, in national or international populations. Four cross-sectional studies (of which 2 international) studied how GALI relates to other health measures (concurrent validity). A dose-response effect by GALI severity level on the association with the other health status measures was observed in the national studies. The 2 international studies (SHARE, EHIS) concluded that the odds of reporting participation restriction was higher in subjects with self-reported or observed functional limitations. In SHARE, the size of the Odds Ratio's (ORs) in the different countries was homogeneous, while in EHIS the size of the ORs varied more strongly. For the predictive validity, subjects were followed over time (4 studies of which one international). GALI proved, both in national and international data, to be a consistent predictor of future health outcomes both in terms of mortality and health care expenditure. As predictors of mortality, the two distinct health concepts, self-rated health and GALI, acted independently and complementary of each other. The one reliability study identified reported a sufficient reliability of GALI. GALI as inclusive one question instrument fits all conceptual characteristics specified for a global measure on participation restriction. In none of the studies, included in the review, there was evidence of a failing validity. The review shows that GALI has a good and sufficient concurrent and predictive validity, and reliability.

AIM: To translate OHIP-14 into Hindi and test its psychometric properties among school teacher community. METHODS: The OHIP-14 was translated to OHIP-14-H using WHO recommended translation protocol. During pre-testing, an expert panel assessed content validity of the questionnaire. Face validity was assessed on a sample of 10 individuals. The OHIP-14-H was administered on a random sample of 170 primary school teachers. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and Intra-class correlation coefficient (ICC) respectively, with 2 weeks interval. Predictive validity was tested by comparing OHIP-14-H scores with clinical parameters. The concurrent validity was assessed using self-reported oral health and discriminant validity was ascertained through negative association with sociodemographic variables. RESULTS: The mean OHIP-14-H score was 9.57 (S.D = 4.58). ICC and Cronbach's alpha for OHIP-14-H was 0.96 and 0.92 respectively. Concurrent validity using binomial regression model indicated that good (OR = 0.56, 95% CI = 0.55 – 4.47) and moderate (OR = 0.25, 95% CI = 0.17 – 1.87) OHIP-14-H scores were negative but significant risk indicators of poor self reported oral health (P < 0.009). Significant predictive validity was observed between OHIP-14-H scores and clinical parameters (P < 0.000). CONCLUSION: Translated and culturally adapted OHIP-14-H indicates good reliability and validity among primary school teachers. PMID:29417064

Quality control and harmonization of data is a vital and challenging undertaking for any successful data coordination center and a responsibility shared between the multiple sites that produce, integrate, and utilize the data. Here we describe a coordinated effort between scientists and data managers in the Cancer Family Registries to implement a data governance infrastructure consisting of both organizational and technical solutions. The technical solution uses a rule-based validation system that facilitates error detection and correction for data centers submitting data to a central informatics database. Validation rules comprise both standard checks on allowable values and a crosscheck of related database elements for logical and scientific consistency. Evaluation over a 2-year timeframe showed a significant decrease in the number of errors in the database and a concurrent increase in data consistency and accuracy.

Investing in financial markets is promoted and protected by the government as an essential economic activity, but can turn into a gambling addiction problem. Until now, few scales have widely been used to identify gambling addicts in financial markets. This study aimed to develop a self-rating scale to distinguish them. In addition, the reliability and validity of the stock addiction inventory (SAI) were demonstrated. A set of questionnaires, including the SAI, south oaks gambling screen (SOGS), and DSM-5 diagnostic criteria, for gambling disorder was completed by 1005 participants. Factor analysis, internal consistency testing, t tests, analysis of variance, and partial correlation analysis were conducted to verify the reliability and validity of SAI. The factor analysis results showed the final SAI consisting of two factors and nine items. The internal consistency and concurrent validity of SAI were verified. The Cronbach's α for the total scale was 0.892, and the SAI and its factors were significantly correlated with SOGS. This study developed a specific scale for financial market investments or trading; this scale proved to be reliable and valid. Our scale expands the understanding of gambling addiction in financial markets and provides a diagnostic reference.

Good knowledge of nutrition is widely thought to be an important aspect to maintaining a balanced and healthy diet. The aim of this study was to develop and validate a new reliable tool to measure the general and the sport nutrition knowledge (GeSNK) in people who used to practice sports at different levels. The development of (GeSNK) was carried out in six phases as follows: (1) item development and selection by a panel of experts; (2) pilot study in order to assess item difficulty and item discrimination; (3) measurement of the internal consistency; (4) reliability assessment with a 2-week test-retest analysis; (5) concurrent validity was tested by administering the questionnaire along with other two similar tools; (6) construct validity by administering the questionnaire to three groups of young adults with different general nutrition and sport nutrition knowledge. The final questionnaire, consisted of 62 items of the original 183 questions. It is a consistent, valid, and suitable instrument that can be applied over time, making it a promising tool to look at the relationship between nutrition knowledge, demographic characteristics, and dietary behavior in adolescents and young adults.

Background/aim: This study aimed to assess the validity and reliability of the Turkish version of the DSM-5 Generalized Anxiety Disorder Severity Scale - Child Form. Materials and methods: The study sample consisted of 32 patients treated in a child psychiatry unit and diagnosed with generalized anxiety disorder and 98 healthy volunteers who were attending middle or high school during the study period. For the assessment, the Screen for Child Anxiety and Related Emotional Disorders (SCARED) was also used along with the DSM-5 Generalized Anxiety Disorder Severity Scale - Child Form. Results: Regarding reliability analyses, the Cronbach alpha internal consistency coefficient was calculated as 0.932. The test-retest correlation coefficient was calculated as r = 0.707. As for construct validity, one factor that could explain 62.6% of the variance was obtained and this was consistent with the original construct of the scale. As for concurrent validity, the scale showed a high correlation with SCARED. Conclusion: It was concluded that Turkish version of the DSM-5 Generalized Anxiety Disorder Severity Scale - Child Form could be utilized as a valid and reliable tool both in clinical practice and for research purposes.

Adaptation and validation of the Portuguese version of the Lithium Knowledge Test (LKT) of bipolar patients treated with lithium: cross-over study

Objective Adherence problems are a common feature among bipolar patients. A recent study showed that lithium knowledge was the main difference between adherent and non adherents bipolar patients. The Lithium Knowledge Test (LKT), a brief questionnaire, was developed as a means of identifying aspects of patients' practical and pharmacological knowledge which are important if therapy is to be safe and effective. The original English version is validated in psychiatric population, but a validated Portuguese one is not yet available. Methods One hundred six patients selected were diagnosed with bipolar disorder (I or II) according to DSM-IV criteria and had to be on lithium treatment for at least one month. The LKT was administered on only one occasion. We analysed the internal consis tency, concurrent validity, sensitivity and specificity of the LKT for the detection of the knowledge about lithium treatment of bipolar patients. Results The internal consistency, evaluated by Cronbach's alpha was 0.596. The mean of total score LKT by bipolar patients was 9.0 (SD: 0.75) for men and 8.74 (SD: 0.44) for women. Concurrent validity based on plasma lithium concentration showed a significant correlation between the total LKT score and plasma lithium (r = 0,232; p = 0.020). The sensitivity was 84% and specificity was 81%. Conclusion LKT is a rapid, reliable instrument which appears to be as effective as a lengthier standard interview with a lithium clinic doctor, and which has a high level of acceptability to lithium patients. We found that the psychometric assessment of the Portuguese version of LKT showed good internal consistency, sensitivity and specificity. PMID:17147815

The study validated a culturally sensitive community living skills rating scale for Chinese patients by adapting the St. Louis Inventory of Community Living Skills (SLICLS). The Chinese version (SLICLS-C) was produced by forward and backward translation. An expert panel evaluated its content validity. Its internal consistency, inter-rater reliability, construct and concurrent validity were tested on 80 DSM-IV schizophrenia inpatients in a long-term facility. For predictive validity, the above sample was extended to ensure at least 20 subjects discharged to each of three levels of community care were included in the study sample. The SLICLS-C was psychometrically sound and could be used for predicting level of community care, program evaluation and measuring outcome.

Despite numerous spirituality and/or religiosity (S/R) measurement tools for use in research worldwide, there is little information on S/R instruments in the Portuguese language. The aim of the present study was to map out the S/R scales available for research in the Portuguese language. Systematic review of studies found in databases. A systematic review was conducted in three phases. Phases 1 and 2: articles in Portuguese, Spanish and English, published up to November 2011, dealing with the Portuguese translation and/or validation of S/R measurement tools for clinical research, were selected from six databases. Phase 3: the instruments were grouped according to authorship, cross-cultural adaptation, internal consistency, concurrent and discriminative validity and test-retest procedures. Twenty instruments were found. Forty-five percent of these evaluated religiosity, 40% spirituality, 10% religious/spiritual coping and 5% S/R. Among these, 90% had been produced in (n = 3) or translated to (n = 15) Brazilian Portuguese and two (10%) solely to European Portuguese. Nevertheless, the majority of the instruments had not undergone in-depth psychometric analysis. Only 40% of the instruments presented concurrent validity, 45% discriminative validity and 15% a test-retest procedure. The characteristics of each instrument were analyzed separately, yielding advantages, disadvantages and psychometric properties. Currently, 20 instruments for measuring S/R are available in the Portuguese language. Most have been translated (n = 15) or developed (n = 3) in Brazil and present good internal consistency. Nevertheless, few instruments have been assessed regarding all their psychometric qualities.

To adapt to Portuguese, of Portugal, the Depression, Anxiety and Stress Scales, a 21-item short scale (DASS 21), designed to measure depression, anxiety and stress. After translation and back-translation with the help of experts, the DASS 21 was administered to patients in external psychiatry consults (N=101), and its internal consistency, construct validity and concurrent validity were measured. The DASS 21 properties certify its quality to measure emotional states. The instrument reveals good internal consistency. Factorial analysis shows that the two-factor structure is more adequate. The first factor groups most of the items that theoretically assess anxiety and stress, and the second groups most of the items that assess depression, explaining, on the whole, 58.54% of total variance. The strong positive correlation between the DASS 21 and the Hospital Anxiety and Depression scale (HAD) confirms the hypothesis regarding the criterion validity, however, revealing fragilities as to the divergence between theoretically different constructs.

Severe Crohn's disease management includes anti-tumor necrosis factor (anti-TNF) drugs that differ from early-stage treatments regarding efficacy, safety, and convenience. This study aimed to finalize and psychometrically validate the Satisfaction for PAtients in Crohn's diseasE Questionnaire (SPACE-Q(©)), developed to measure satisfaction with anti-TNF treatment in patients with severe Crohn's disease. A total of 279 patients with severe Crohn's disease receiving anti-TNF therapy completed the SPACE-Q 62-item pilot version at inclusion and 12 and 13 weeks after first anti-TNF injection. The final SPACE-Q scoring was defined using multitrait and regression analyses and clinical relevance considerations. Psychometric validation included clinical validity against Harvey-Bradshaw score, concurrent validity against Treatment Satisfaction Questionnaire for Medication (TSQM), internal consistency reliability, test-retest reliability, and responsiveness against the patient global impression of change (PGIC). Quality of completion was good (55%-67% of patients completed all items). Four items were removed from the questionnaire. Eleven scores were defined within the final 58-item SPACE-Q: disease control; symptoms, anal symptoms, and quality of life transition scales; tolerability; convenience; expectation confirmation toward efficacy, side effects, and convenience; satisfaction with treatment; and motivation. Scores met standards for concurrent validity (correlation between SPACE-Q satisfaction with treatment and TSQM satisfaction scores =0.59), internal consistency reliability (Cronbach's α=0.67-0.93), test-retest reliability (intraclass correlations =0.62-0.91), and responsiveness (improvement in treatment experience assessed by the SPACE-Q for patients reporting improvement on the PGIC). Significantly different mean scores were observed between groups of patients with different Harvey-Bradshaw disease severity scores. The SPACE-Q is a valid, reliable, and responsive instrument to measure satisfaction with anti-TNF treatment in patients with severe Crohn's disease and for use in future studies.

Validating a questionnaire/instrument before proceeding to the field for data collection is important. An 18-item breastfeeding intention, 39-item attitude and 44-item knowledge questionnaire was validated in a Croatian sample of secondary-school students ( N = 277). For the intentions, principal component analysis (PCA) yielded a four-factor solution with 8 items explaining 68.3% of the total variance. Cronbach’s alpha (0.71) indicated satisfactory internal consistency. For the attitudes, PCA showed a seven-factor structure with 33 items explaining 58.41% of total variance. Cronbach’s alpha (0.87) indicated good internal consistency. There were 13 knowledge questions that were retained after item analysis, showing good internal consistency (KR20 = 0.83). In terms of criterion validity, the questionnaire differentiated between students who received breastfeeding education compared to students who were not educated in breastfeeding. Correlations between intentions and attitudes (r = 0.49), intentions and knowledge (r = 0.29), and attitudes and knowledge (r = 0.38) confirmed concurrent validity. The final instrument is reliable and valid for data collection on breastfeeding. Therefore, the instrument is recommended for evaluation of breastfeeding education programs aimed at upper-grade elementary and secondary school students.

Working conditions substantially influence health, work ability and sick leave. Useful instruments to help clinicians pay attention to working conditions are lacking in primary care (PC). The aim of this study was to test the validity of a short "Blue flags" questionnaire, which focuses on work-related psychosocial risk factors and any potential need for contacts and/or actions at the workplace. From the original"The General Nordic Questionnaire" (QPS Nordic ) the research group identified five content areas with a total of 51 items which were considered to be most relevant focusing on work-related psychosocial risk factors. Fourteen items were selected from the identified QPS Nordic content areas and organised in a short questionnaire "Blue flags". These 14 items were validated towards the 51 QPS Nordic items. Content validity was reviewed by a professional panel and a patient panel. Structural and concurrent validity were also tested within a randomised clinical trial. The two panels (n = 111) considered the 14 psychosocial items to be relevant. A four-factor model was extracted with an explained variance of 25.2%, 14.9%, 10.9% and 8.3% respectively. All 14 items showed satisfactory loadings on all factors. Concerning concurrent validity the overall correlation was very strong r s  = 0.87 (p < 0.001).). Correlations were moderately strong for factor one, r s  = 0.62 (p < 0.001) and factor two, r s  = 0.74 (p < 0.001). Factor three and factor four were weaker, bur still fair and significant at r s  = 0.53 (p < 0.001) and r s  = 0.41 (p < 0.001) respectively. The internal consistency of the whole "Blue flags" was good with Cronbach's alpha of 0.76. The content, structural and concurrent validity were satisfactory in this first step of development of the "Blue flags" questionnaire. In summary, the overall validity is considered acceptable. Testing in clinical contexts and in other patient populations is recommended to ensure predictive validity and usefulness.

Cross-sectional validation and reliability assessment study of Arabic version of Scoliosis Research Society-22 (SRS-22r) Questionnaire. To develop and validate the Arabic version of the SRS-22r questionnaire. The diagnosis and treatment of adolescent idiopathic scoliosis may influence patient quality of life. SRS-22r is an internationally validated questionnaire used to assess function/activity, pain, self-image, and mental health of patients with scoliosis. It has been translated into several languages but not into Arabic language. Therefore, a valid health-related quality-of-life outcome questionnaire for patients with spinal deformity is still lacking in Arabic language. The English version of SRS-22r questionnaire was translated, back-translated, and culturally adapted to Arabic language. Then, 81 patients with idiopathic adolescent scoliosis were allocated randomly into either the reliability testing group (group 1) or the validity testing group (group 2). Group 1 patients completed Arabic version of SRS-22r questionnaire twice with 1-week interval in-between. Cronbach α and intraclass correlation coefficient were measured to determine internal consistency and temporal reliability. Group 2 patients completed the Arabic version of SRS-22r questionnaire and the previously validated Arabic version of 36-Item Short Form Health Survey (Short Form-36) questionnaire concurrently, and Pearson correlation coefficient was obtained to assess validity. Content analysis, internal consistency reliability, test/retest reproducibility (intraclass correlation coefficient range: 0.82-0.90), and test of concurrent validity showed satisfactory results. Function/activity and satisfaction with management domains had a lower Cronbach α (0.58 and 0.44, respectively, vs. 0.71-0.85 range for others). Self-image/appearance and satisfaction with management had a lower correlation with domains of the 36-Item Short Form Health Survey. An Arabic version of the SRS-22r questionnaire has been developed and validated. This questionnaire will aid health care workers and researchers in evaluation of patient perception of the deformity, satisfaction with treatment, and quality of life in Arabic-speaking populations. 3.

To describe the derivation of recent status scores (RSSs) for version 6 of the Addiction Severity Index (ASI-6). 118 ASI-6 recent status items were subjected to nonparametric item response theory (NIRT) analyses followed by confirmatory factor analysis (CFA). Generalizability and concurrent validity of the derived scores were determined. A total of 607 recent admissions to variety of substance abuse treatment programs constituted the derivation sample; a subset (n = 252) comprised the validity sample. The ASI-6 interview and a validity battery of primarily self-report questionnaires that included at least one measure corresponding to each of the seven ASI domains were administered. Nine summary scales describing recent status that achieved or approached both high scalability and reliability were derived; one scale for each of six areas (medical, employment/finances, alcohol, drug, legal, psychiatric) and three scales for the family/social area. Intercorrelations among the RSSs also supported the multi-dimensionality of the ASI-6. Concurrent validity analyses yielded strong evidence supporting the validity of six of the RSSs (medical, alcohol, drug, employment, family/social problems, psychiatric). Evidence was weaker for the legal, family/social support and child problems RSSs. Generalizability analyses of the scales to males versus females and whites versus blacks supported the comparability of the findings, with slight exceptions. The psychometric analyses to derive Addiction Severity Index version 6 recent status scores support the multi-dimensionality of the Addiction Severity Index version 6 (i.e. the relative independence of different life functioning areas), consistent with research on earlier editions of the instrument. In general, the Addiction Severity Index version 6 scales demonstrate acceptable scalability, reliability and concurrent validity. While questions remain about the generalizability of some scales to population subgroups, the overall findings coupled with updated and more extensive content in the Addiction Severity Index version 6 support its use in clinical practice and research. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

Objective Concerns over behavioral and emotional problems caused by excessive internet usage have been developed. This study intended to develop and a standardize questionnaire that can efficiently identify at-risk internet users through their internet usage habits. Methods Participants (n=158) were recruited at six I-will-centers located in Seoul, South Korea. From the initial 36 questionnaire item pool, 28 preliminary items were selected through expert evaluation and panel discussions. The construct validity, internal consistency, and concurrent validity were examined. We also conducted Receiver Operating Curve (ROC) analysis to assess diagnostic ability of the Internet Overuse Screening-Questionnaire (IOS-Q). Results The exploratory factor analysis yielded a five factor structure. Four factors with 17 items remained after items that had unclear factor loading were removed. The Cronbach’s alpha for the IOS-Q total score was 0.91, and test-retest reliability was 0.72. The correlation between Young’s internet addiction scale and K-scale supported concurrent validity. ROC analysis showed that the IOS-Q has superior diagnostic ability with the Area Under the Curve of 0.87. At the cut-off point of 25.5, the sensitivity was 0.93 and specificity was 0.86. Conclusion Overall, this study supports the use of IOS-Q for internet addiction research and for screening high-risk individuals. PMID:29669406

We developed a focused, context-specific measure of sales self-efficacy and assessed its incremental validity against the broad Big 5 personality traits with department store salespersons, using (a) both a concurrent and a predictive design and (b) both objective sales measures and supervisory ratings of performance. We found that in the concurrent study, sales self-efficacy predicted objective and subjective measures of job performance more than did the Big 5 measures. Significant differences between the predictability of subjective and objective measures of performance were not observed. Predictive validity coefficients were generally lower than concurrent validity coefficients. The results suggest that there are different dynamics operating in concurrent and predictive designs and between broad and contextualized measures; they highlight the importance of distinguishing between these designs and measures in meta-analyses. The results also point to the value of focused, context-specific personality predictors in selection research. PsycINFO Database Record (c) 2013 APA, all rights reserved.

To develop and provide validity and feasibility evidence for the QUality of Information Transfer (QUIT) tool. Prompt escalation of care in the setting of patient deterioration can prevent further harm. Escalation and information transfer skills are not currently measured in surgery. This study comprised 3 phases: the development (phase 1), validation (phase 2), and feasibility analysis (phase 3) of the QUIT tool. Phase 1 involved identification of core skills needed for successful escalation of care through literature review and 33 semistructured interviews with stakeholders. Phase 2 involved the generation of validity evidence for the tool using a simulated setting. Thirty surgeons assessed a deteriorating postoperative patient in a simulated ward and escalated their care to a senior colleague. The face and content validity were assessed using a survey. Construct and concurrent validity of the tool were determined by comparing performance scores using the QUIT tool with those measured using the Situation-Background-Assessment-Recommendation (SBAR) tool. Phase 3 was conducted using direct observation of escalation scenarios on surgical wards in 2 hospitals. A 7-category assessment tool was developed from phase 1 consisting of 24 items. Twenty-one of 24 items had excellent content validity (content validity index >0.8). All 7 categories and 18 of 24 (P < 0.05) items demonstrated construct validity. The correlation between the QUIT and SBAR tools used was strong indicating concurrent validity (r = 0.694, P < 0.001). Real-time scoring of escalation referrals was feasible and indicated that doctors currently have better information transfer skills than nurses when faced with a deteriorating patient. A validated tool to assess information transfer for deteriorating surgical patients was developed and tested using simulation and real-time clinical scenarios. It may improve the quality and safety of patient care on the surgical ward.

Working memory is an important predictor of academic performance, and of math performance in particular. Most working memory tasks depend on one-to-one administration by a testing assistant, which makes the use of such tasks in large-scale studies time-consuming and costly. Therefore, an online, self-reliant visual-spatial working memory task (the Lion game) was developed for primary school children (6-12 years of age). In two studies, the validity and reliability of the Lion game were investigated. The results from Study 1 (n = 442) indicated satisfactory six-week test-retest reliability, excellent internal consistency, and good concurrent and predictive validity. The results from Study 2 (n = 5,059) confirmed the results on the internal consistency and predictive validity of the Lion game. In addition, multilevel analysis revealed that classroom membership influenced Lion game scores. We concluded that the Lion game is a valid and reliable instrument for the online computerized and self-reliant measurement of visual-spatial working memory (i.e., updating).

The aim of this study was to develop a screening questionnaire that could distinguish individuals at high risk of smartphone overuse from casual users. The reliability, validity, and diagnostic ability of the Smartphone Overuse Screening Questionnaire (SOS-Q) were evaluated. Preliminary items were assessed by 50 addiction experts on-line, and 28 questions were selected. A total of 158 subjects recruited from six community centers for internet addiction participated in this study. The SOS-Q, Young's internet addiction scale, Korean scale for internet addiction, and Smartphone Scale for Smartphone Addiction (S-Scale) were used to assess the concurrent validity. Construct validity was supported by a six-factor model using an exploratory factor analysis. The internal consistency and the item-total correlations were favorable (α = 0.95, r = 0.35-0.81). The test-retest reliability was moderate (r = 0.70). The SOS-Q showed superior concurrent validity with the highest correlation between the S-Scale (r = 0.76). Receiver operating characteristic curve analysis revealed an area under the curve of 0.877. A cut-off point of 49 effectively categorized addiction high-risk group with a sensitivity of 0.81 and specificity of 0.86. Overall, the current study supports the use of SOS-Q as both a primary and supplementary measurement tool in a variety of settings. Copyright © 2017 Elsevier B.V. All rights reserved.

The Star Excursion Balance Test (SEBT) has frequently been used to measure motor control and residual functional deficits at different stages of recovery from lateral ankle sprain (LAS) in various populations. However, the validity of the measure used to characterize performance--the maximal reach distance (MRD) measured by visual estimation--is still unknown. To evaluate the concurrent validity of the MRD in the SEBT estimated visually vs the MRD measured with a 3D motion-capture system and evaluate and compare the discriminant validity of 2 MRD-normalization methods (by height or by lower-limb length) in participants with or without LAS (n = 10 per group). There is a high concurrent validity and a good degree of accuracy between the visual estimation measurement and the MRD gold-standard measurement for both groups and under all conditions. The Cohen d ratios between groups and MANOVA products were higher when computed from MRD data normalized by height. The results support the concurrent validity of visual estimation of the MRD and the use of the SEBT to evaluate motor control. Moreover, normalization of MRD data by height appears to increase the discriminant validity of this test.

The aim of this study was to investigate symptoms of social anxiety and the psychometric properties of the Social Anxiety Scale for Adolescents (SAS-A) among Finnish adolescents, 13-16 years of age. Study 1 (n = 867) examined the distribution of SAS-A scores according to gender and age, and the internal consistency and factor structure of the SAS-A. In a subsample (n = 563; Study 2) concurrent and discriminant validity of the SAS-A were examined relative to the Social Phobia Inventory and the Beck Depression Inventory. Test-retest stability was examined over a 30-month period by repeated measures every 6 months in another subsample (n = 377; Study 3). Results mostly revealed no gender differences in social anxiety, except that boys reported more general social avoidance and distress than girls. Older adolescents (14-16-year-olds) reported higher social anxiety than younger adolescents (12-13-year-olds). Internal consistency for the SAS-A was acceptable for both genders and for all three SAS-A subscales. Confirmatory factor analysis replicated the original 18-item three-factor structure of the SAS-A, accounting for 61% of the variance between items. Evidence for concurrent and discriminant validity was found. Test-retest stability over 6 months was satisfactory. Results support the reliability and validity of the Finnish adaptation of the SAS-A, and further indicate that gender differences in adolescents' social anxiety may vary across Western countries.

Background: Psychologic factors affect how patients with COPD respond to attempts to improve their self-management skills. Learned helplessness may be one such factor, but there is no validated measure of helplessness in COPD. Methods: We administered a new COPD Helplessness Index (CHI) to 1,202 patients with COPD. Concurrent validity was assessed through association of the CHI with established psychosocial measures and COPD severity. The association of helplessness with incident COPD exacerbations was then examined by following subjects over a median 2.1 years, defining COPD exacerbations as COPD-related hospitalizations or ED visits. Results: The CHI demonstrated internal consistency (Cronbach α = 0.75); factor analysis was consistent with the CHI representing a single construct. Greater CHI-measured helplessness correlated with greater COPD severity assessed by the BODE (Body-mass, Obstruction, Dyspnea, Exercise) Index (r = 0.34; P < .001). Higher CHI scores were associated with worse generic (Short Form-12, Physical Component Summary Score) and respiratory-specific (Airways Questionnaire 20) health-related quality of life, greater depressive symptoms, and higher anxiety (all P < .001). Controlling for sociodemographics and smoking status, helplessness was prospectively associated with incident COPD exacerbations (hazard ratio = 1.31; P < .001). After also controlling for the BODE Index, helplessness remained predictive of COPD exacerbations among subjects with BODE Index ≤ median (hazard ratio = 1.35; P = .01), but not among subjects with higher BODE Index values (hazard ratio = 0.93; P = .34). Conclusions: The CHI is an internally consistent and valid measure, concurrently associated with health status and predictively associated with COPD exacerbations. The CHI may prove a useful tool in analyzing differential clinical responses mediated by patient-centered attributes. PMID:19837823

The purpose of this report is to investigate the concurrent validity of the Defense and Veterans Pain Rating Scale (DVPRS) with other validated self-report measures in U.S. veterans. This correlational study was conducted using two samples of outpatients at the Washington, DC Veterans Affairs Medical Center who completed self-report measures relevant to pain conditions, including pain disability, quality of life, and mental health. Study 1 and 2 consisted of n = 204 and n = 13 participants, respectively. Bivariate Spearman correlations were calculated to examine the correlation among total scores and subscale scores for each scale of interest. Multiple linear regressions were also computed in Study 1. In Study 1, the DVPRS interference scale (DVPRS-II) was significantly correlated with the Pain Disability Questionnaire (PDQ) (ρ = 0.69, P < 0.001) and the Veterans RAND 36-item Health Survey physical and mental component scales (ρ = -0.37, P < 0.001; ρ = -0.46, P < 0.001, respectively). When controlling for sex, age, and other self-report measures, the relationship between the DVPRS-II and PDQ remained significant. In Study 2, pain interference on the DVPRS and Brief Pain Inventory were highly correlated (ρ = 0.90, P < 0.001); however, the intensity scale of each measure was also highly associated with the interference summary scores. These findings provide preliminary evidence for the concurrent validity of the DVPRS as a brief, multidimensional measure of pain interference that make it a practical tool for use in primary care settings to assess the impact of pain on daily functioning and monitor chronic pain over time.

To evaluate the concurrent validity of a clinical decision support tool (Work Assessment Triage Tool (WATT)) developed to select rehabilitation treatments for injured workers with musculoskeletal conditions. Methodological study with cross-sectional and prospective components. Data were obtained from the Workers' Compensation Board of Alberta rehabilitation facility in Edmonton, Canada. A total of 432 workers' compensation claimants evaluated between November 2011 and June 2012. Percentage agreement between the Work Assessment Triage Tool and clinician recommendations was used to determine concurrent validity. In claimants returning to work, frequencies of matching were calculated and compared between clinician and Work Assessment Triage Tool recommendations and the actual programs undertaken by claimants. The frequency of each intervention recommended by clinicians, Work Assessment Triage Tool, and case managers were also calculated and compared. Percentage agreement between clinician and Work Assessment Triage Tool recommendations was poor (19%) to moderate (46%) and Kappa = 0.37 (95% CI -0.02, 0.76). The Work Assessment Triage Tool did not improve upon clinician recommendations as only 14 out of 31 claimants returning to work had programs that contradicted clinician recommendations, but were consistent with Work Assessment Triage Tool recommendations. Clinicians and case managers were inclined to recommend functional restoration, physical therapy, or no rehabilitation while the Work Assessment Triage Tool recommended additional evidence-based interventions, such as workplace-based interventions. Our findings do not provide evidence of concurrent validity for the Work Assessment Triage Tool compared with clinician recommendations. Based on these results, we cannot recommend further implementation of the Work Assessment Triage Tool. However, the Work Assessment Triage Tool appeared more likely than clinicians to recommend interventions supported by evidence; thus warranting further research. © The Author(s) 2015.

There are many nutrition screening tools currently being applied in hospitals to identify risk of malnutrition. However, multivariate statistical models are not usually employed to take into account the importance of each variable included in the instrument's development. To develop and evaluate the concurrent and predictive validities of a new screening tool of nutrition risk. A prospective cohort study was developed, in which 4 nutrition screening tools were applied to all patients. Length of stay in hospital and mortality were considered to test the predictive validity, and the concurrent validity was tested by comparing the Nuritional Risk in Emergency (NRE)-2017 to the other tools. A total of 748 patients were included. The final NRE-2017 score was composed of 6 questions (advanced age, metabolic stress of the disease, decreased appetite, changing of food consistency, unintentional weight loss, and muscle mass loss) with answers yes or no. The prevalence of nutrition risk was 50.7% and 38.8% considering the cutoff points 1.0 and 1.5, respectively. The NRE-2017 showed a satisfactory power to indentify risk of malnutrition (area under the curve >0.790 for all analyses). According to the NRE-2017, patients at risk of malnutrition have twice as high relative risk of a very long hospital stay. The hazard ratio for mortality was 2.78 (1.03-7.49) when the cutoff adopted by the NRE-2017 was 1.5 points. NRE-2017 is a new, easy-to-apply nutrition screening tool which uses 6 bi-categoric features to detect the risk of malnutrition, and it presented a good concurrent and predictive validity. © 2018 American Society for Parenteral and Enteral Nutrition.

Type 2 diabetes mellitus (T2DM) self-management among Hispanic adults occurs in a family context. Self-efficacy (SE) affects T2DM self-management behaviors; however, no instruments are available to measure family diabetes self-efficacy. The study's purpose was to test the psychometric properties of the Family Self-Efficacy for Diabetes Scale (FSE). Family members (n = 113) of adults with T2DM participated. Psychometric analysis included internal consistency reliability and concurrent and construct validity. Internal consistency reliability was .86. Items loaded on 2 factors, Family SE for Supporting Healthy Behaviors and Family SE for Supporting General Health, accounting for 71% of the variance. FSE correlated significantly with 3 diabetes-related instruments. The FSE is a reliable and valid instrument. Further testing is needed in diverse populations and geographic areas.

2017-10-01

The aim of this study was to develop a Spanish version of the Adolescent Stress Questionnaire and to examine its psychometric properties: factor structure, measurement invariance across samples, reliability, and concurrent validity. Participants consisted of 1,560 Spanish students between 12 and 18 years of age. The results support a structure based on 10 first-order factors (corresponding to stressors on the dimensions Home Life, School Performance, School Attendance, Romantic Relationships, Peer Pressure, Teacher Interaction, Future Uncertainty, School/Leisure Conflict, Financial Pressure, and Emerging Adult Responsibility) and 1 second-order factor that subsumes the first-order factors. This model was selected for measurement invariance testing because it showed good fit indexes and was more parsimonious than the first-order factor model. This structure was replicated across 2 independent samples from the same population, as well as across 3 age groups (early, middle, and late adolescence), showing acceptable fit for all groups. Internal consistency and test-retest reliability were adequate. Evidence of concurrent validity was provided by positive associations with measures of stress manifestations, anxiety, and depression, and by a negative association with life satisfaction. The results indicate that the Spanish version of the Adolescent Stress Questionnaire is a suitable tool for assessing stressors in Spanish adolescents.

This study aimed to evaluate the reliability and validity of the Korean version of the Mini-Sleep Questionnaire-Insomnia in Korean college students. A total of 470 students from six nursing colleges in South Korea participated in the study. The translation and linguistic validation of the Mini-Sleep Questionnaire-Insomnia was performed based on guidelines. The Pittsburgh Sleep Quality Index and the Perceived Stress Scale were used to validate the measure. Cronbach α, item-total correlation for internal consistency reliability and intraclass correlation coefficient for test-retest reliability were evaluated. Exploratory factor analysis for construct validity, Pearson's correlation with the Pittsburgh Sleep Quality Index and the Perceived Stress Scale for concurrent validity, and the receiver operating character curve for predictive validity were assessed. The 4-item Mini-Sleep Questionnaire-Insomnia had a Cronbach α of .69 and the item-total correlations were higher than .30. Cronbach α increased to .73 if the item assessing the use of sleeping pills and tranquilizers was deleted. This item had marked skewness and kurtosis issues. Factor analysis indicated unidimensionality, explaining 53.0% of the total variance. The measure showed high test-retest reliability (i.e., intraclass correlation coefficient = .84), acceptable concurrent validity (r with the Pittsburg Sleep Quality Index = .69; r with the Perceived Stress Scale = .31) and predictive validity [area under curve = .85; 95% confidence interval (0.81, 0.90)]. The Mini-Sleep Questionnaire-Insomnia showed acceptable reliability and validity. Yet, the limited distribution in sleep medications warrants further evaluations in the clinical population.

Depression in patients with heart failure commonly goes undiagnosed and untreated. The Patient Health Questionnaire-9 (PHQ-9) is a simple, valid measure of depressive symptoms that may facilitate clinical assessment. It has not been validated in patients with heart failure. To test the reliability, and concurrent and construct validity of the PHQ-9 in patients with heart failure. A total of 322 heart failure patients (32% female, 61 ± 12 years, 56% New York Heart Association class III/IV) completed the PHQ-9, the Beck Depression Inventory-II (BDI-II), and the Control Attitudes Scale (CAS). Cronbach's alpha of .83 supported the internal consistency reliability of the PHQ-9 in this sample. Inter-item correlations (range .22-.66) and item-total correlation (except item 9) supported homogeneity of the PHQ-9. Spearman's rho of .80, (p < .001) between the PHQ-9 and the BDI-II supported the concurrent validity as did the agreement between the PHQ-9 and the BDI-II (Kappa = 0.64, p < .001). At cut-off score of 10, the PHQ-9 was 70% sensitive and 92% specific in identifying depressive symptoms, using the BDI-II scores as the criterion for comparison. Differences in PHQ-9 scores by level of perceived control measured by CAS (t(318) = -5.05, p < .001) supported construct validity. The PHQ-9 is a reliable, valid measure of depressive symptoms in patients with heart failure.

Nutrition is an important aspect of chronic disease prevention and management by primary health professionals, including GPs, dietitians, practice nurses, diabetes educators and exercise professionals. In order to better understand how to improve the delivery of nutrition care, it is important to have valid and reliable tools to measure self-perceived competence. This study aimed to develop a valid, structured, questionnaire that measures the self-perceived competence of primary health professionals to provide nutrition care to patients with chronic disease. The development of the questionnaire was carried out in four stages (1): preparation of scope and structure, through a literature review and consultation with an expert reference group (2); development of questionnaire items, which were refined through feedback from the reference group and 18 primary health professionals (3); investigation of internal consistency and concurrent validity through a pilot study on 118 primary health professionals (4) and investigation of test-retest reliability through a pilot study on 33 primary health professionals who completed the questionnaire twice, 2-3 weeks apart. Stages 1 and 2 resulted in four constructs and 35 questions in the questionnaire. Stage 3 confirmed internal consistency, with Cronbach's α ranging from 0.88 to 0.98 for each construct and 0.98 for all items combined. Dietitians scored significantly higher than speech pathologists (P < 0.05) in each construct, confirming concurrent validity. Stage 4 confirmed test-retest reliability, with correlation coefficients ranging from 0.89 to 0.94 for each construct and 0.95 for all items combined. The NUTrition COMPetence (NUTCOMP) questionnaire is a valid, reliable and suitable tool that can be used to directly inform professional development and identify opportunities to support safe and effective practice. © The Author 2015.

Kruizinga, Ingrid; Jansen, Wilma; de Haan, Carolien L.; Raat, Hein

2012-01-01

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

Research shows that Latino parenting practices influence children's dietary and weight outcomes. Most studies use parent-reported data, however data from children may provide additional insight into how parents influence their children's diet and weight outcomes. The Parenting Strategies for Eating and Activity Scale (PEAS) has been validated in Latino adults, but not in children. This study evaluated the factor structure and concurrent and predictive validity of a modified version of the PEAS (PEAS-Diet) among Latino children. Data were collected from 361 children ages 7-13 from Imperial County, California, enrolled in a randomized controlled trial to promote healthy eating. The PEAS-Diet included 25 candidate items targeting six parenting practices pertaining to children's eating behaviors: (a) monitoring; (b) disciplining; (c) control; (d) permissiveness; (e) reinforcing; and (f) limit-setting. Children were on average ten years old (±2), 50% boys, 93% self-identified as Latino, 81% were US-born, and 55% completed English versus Spanish-language interviews. Using varimax rotation on baseline data with the total sample, six items were removed due to factor loadings <.40 and/or cross-loading (>.32 on more than one component). Parallel analysis and interpretability suggested a 5-factor solution explaining 59.46% of the variance. The subscale "limit-setting" was removed from the scale. The final scale consisted of 19 items and 5 subscales. Internal consistency of the subscales ranged from α = .63-.82. Confirmatory factor analyses provided additional evidence for the 5-factor scale using data collected 4 and 6 months post-baseline among the control group (n = 164, n = 161, respectively). Concurrent validity with dietary intake was established for monitoring, control, permissiveness, and reinforcing subscales in the expected directions. Predictive validity was not established. Results indicated that with the reported changes, the interview-administered PEAS-Diet is valid among Latino children aged 7-13 years. Copyright © 2015 Elsevier Ltd. All rights reserved.

To investigate the inter-rater and intra-rater reliability, construct validity and internal consistency of the Brazilian version of the Nottingham Sensory Assessment for Stroke Patients (NSA). The instrument was translated into Portuguese from its original in English by a bilingual translator and was then back-translated into English. Twenty-one hemiparetics were evaluated by two examiners using the NSA and the Fugl-Meyer Assessment (FMA) of physical performance. Significant correlation were found between the FMA and the NSA (r=0.752). The NSA showed excellent internal consistency (0.86), and there were acceptable inter- and intra-rater reliability for all items of the NSA, except temperature. Significant ceiling effects were found for the NSA and the FMA. The Brazilian version of the NSA met the criteria for agreement, internal consistency and concurrent validity. It was quick and easy to apply, and it could be used within clinical practice in neuro-rehabilitation outpatient clinics to assess sensory functions following stroke. The significant ceiling effect for the NSA did not limit its use, given that for the same patients, the FMA also showed ceiling effects.

Commitment to change is an innovative potential mediator or mechanism of behavior change that has not been examined in adolescents with substance use disorders (SUD). The Adolescent Substance Abuse Goal Commitment (ASAGC) questionnaire is a 16-item measure developed to assess an individual's commitment to his/her stated treatment goal. The objectives of this study are to explore the research and clinical utility of the commitment construct as measured by the ASAGC. During sessions 3 and 9 of a 10-week SUD treatment, therapists completed the ASAGC for 170 13-18 year-old adolescents. An exploratory factor analysis was conducted on the ATAGC items. Concurrent validity with related constructs, self-efficacy and motivation for change, was examined as well. At both sessions, the factor analysis resulted in two scales--Commitment to Recovery and Commitment to Harm Reduction. The ASAGC scales were found to demonstrate a high level of internal consistency (alpha coefficients ranged from .92 to .96 over time). In contrast to the Commitment to Harm Reduction scale, the Commitment to Recovery scale consistently correlated with scales from the Situational Confidence Questionnaire assessing self-efficacy, evidencing concurrent validity. Similarly, the Commitment to Recovery scale was related to the Problem Recognition Questionnaire, providing further evidence of the validity of the ASAGC. The ASAGC is a reliable and valid clinical research instrument for the assessment of adolescents' commitment to their substance abuse treatment goal. Clinical researchers may take advantage of the clinical utility of the ASAGC including its ability to differentiate between commitment to abstinence versus commitment to harm reduction.

Background By permitting remote assessments of patients and research participants, telemedicine has the potential to reshape clinical care and clinical trials for Parkinson disease. While the majority of the motor Unified Parkinson’s Disease Rating Scale (UPDRS) items can be conducted visually, rigidity and retropulsion pull testing require hands-on assessment by the rater and are less feasible to perform remotely in patients' homes. Methods In a secondary data analysis of the Comparison of the Agonist pramipexole vs. Levodopa on Motor complications in Parkinson’s Disease (CALM-PD) study, a randomized clinical trial, we assessed the cross-sectional (baseline and 2 years) and longitudinal (change from baseline to 2 years) reliability of a modified motor UPDRS (removing rigidity and retropulsion items) compared to the standard motor UPDRS (all items) using intraclass correlation coefficients (ICC), stratified by treatment group. Internal consistency of the modified UPDRS (mUPDRS) was measured using Cronbach’s alpha, and concurrent validity was assessed using Pearson’s correlation coefficient (r) between the standard motor UPDRS and mUPDRS. Results The mUPDRS versus standard motor UPDRS is cross-sectionally (ICC ≥ 0.92) and longitudinally (ICC ≥ 0.92) reliable for both treatment groups. High internal consistencies were also observed (α ≥ 0.96). The mUPDRS had high concurrent validity with the standard UPDRS at both time points and longitudinally (r ≥ 0.93, p < 0.0001). Conclusions A modified version of the motor UPDRS without rigidity and retropulsion pull testing is reliable and valid and may lay the foundation for its use in remote assessments of patients and research participants.

Objective Cognitive symptoms are an important component of depression and the Perceived Deficits Questionnaire-Depression is one of only a few instruments available for the subjective assessment of cognitive dysfunction in depression. Thus, the present study aimed to validate a Korean version of the PDQ-D (K-PDQ-D) using patients with major depressive disorder (MDD). Methods This study included 128 MDD patients who were assessed at study entry and 86 of these patients were then completed 12 weeks of antidepressant monotherapy. All subjects were assessed with the K-PDQ-D, the Montgomery-Asberg Depression Rating Scale (MADRS), the Sheehan Disability Scale (SDS), the EuroQol-5 dimensions questionnaire (EQ-5D), and the number of sick leave days taken in the previous week. The internal consistency, Guttman’s split-half and test-retest reliabilities, factorial analyses, and concurrent and predictive validities of the K-PDQ-D were investigated. Results The K-PDQ-D exhibited excellent internal consistency and reliabilities, and was composed of four factors with high coefficients of determination. The concurrent validity analyses revealed that the K-PDQ-D scores were significantly correlated with the MADRS, SDS, and EQ-5D scores and the number of sick leave days taken. The K-PDQ-D scores at study entry significantly predicted changes in sick leave days and EQ-5D score from study entry to the 12-week endpoint. Conclusion The newly developed K-PDQ-D is a reliable and valid instrument for the evaluation of subjective cognitive symptoms in MDD patients. The K-PDQ-D may assist in the gathering of unique information regarding subjective cognitive complaints, which is important for the comprehensive evaluation of patients with MDD. PMID:26792037

The purpose of this study was to develop work-family-school role conflicts and role-related social support scales, and to validate the psychometrics of those scales among registered nurses with multiple roles. The concepts, generation of items, and the scale domains of work-family-school role conflicts and role-related social support scales were constructed based on a review of the literature. The validity and reliability of the scales were examined by administering them to 201 registered nurses who were recruited from 8 university hospitals in South Korea. The content validity was examined by nursing experts using a content validity index. Exploratory factor analysis and confirmatory factor analysis were used to establish the construct validity. The correlation with depression was examined to assess concurrent validity. Finally, internal consistency was assessed using Cronbach's alpha coefficients. The work-family-school role conflicts scale comprised ten items with three factors: work-school-to-family conflict (three items), family-school-to-work conflict (three items), and work-family-to-school conflict (four items). The role-related social support scale comprised nine items with three factors: support from family (three items), support from work (three items), and support from school (three items). Cronbach's alphas were 0.83 and 0.76 for the work-family-school role conflicts and role-related social support scales, respectively. Both instruments exhibited acceptable construct and concurrent validity. The validity and reliability of the developed scales indicate their potential usefulness for the assessment of work-family-school role conflict and role-related social support among registered nurses with multiple roles in Korea.

To evaluate the reliability, validity, and responsiveness of the Italian OMES (I-OMES). The study consisted of 3 phases: (1) internal consistency and reliability, (2) validity, and (3) responsiveness analysis. The recruited population included 27 patients with orofacial myofunctional disorders (OMD) and 174 healthy volunteers. Forty-seven subjects, 18 healthy and all recruited patients with OMD were assessed for inter-rater and test-retest reliability analysis. I-OMES and Nordic Orofacial Test - Screening (NOT-S) scores of the patients were correlated for concurrent validity analysis. I-OMES scores from 27 patients with OMD and 27 age- and gender-matched healthy subjects were compared to investigate construct validity. I-OMES scores before and after successful swallowing rehabilitation in patients were compared for responsiveness analysis. Adequate internal consistency (Cronbach α = 0.71) and strong inter-rater and test-retest reliability (intraclass coefficient correlation = 0.97 and 0.98, respectively) were found. I-OMES and NOT-S scores significantly and inversely correlated (r = -0.38). A statistical significance (p < 0.001) was found between the pathological group and the control group for the total I-OMES score. The mean I-OMES score improved from 90 (78-102) to 99 (89-103) after myofunctional rehabilitation (p < 0.001). The I-OMES is a reliable and valid tool to evaluate OMD. © 2018 S. Karger AG, Basel.

The Impact of Cancer version 2 (IOCv2) was designed to assess the physical and psychosocial health experience of cancer survivors through its positive and negative impacts. Although the IOCv2 is available in English and Dutch, it has not yet been validated for use in French-speaking populations. The current study was undertaken to provide a comprehensive assessment of the reliability and validity of the French language version of the IOCv2 in a sample of breast cancer survivors. An adapted French version of the IOCv2 as well as demographic and medical information were completed by 243 women to validate the factor structure divergent/divergent validities and reliability. Concurrent validity was assessed by correlating the IOCv2 scales with measures from the SF-12, PostTraumatic Growth Inventory and Fear of Cancer Recurrence Inventory. The French version of the IOCv2 supports the structure of the original version, with four positive impact dimensions and four negative impact dimensions. This result was suggested by the good fit of the confirmatory factor analysis and the adequate reliability revealed by Cronbach's alpha coefficients and other psychometric indices. The concurrent validity analysis revealed patterns of association between IOCv2 scale scores and other measures. Unlike the original version, a structure with a Positive Impact domain consisting in the IOCv2 positive dimensions and a Negative Impact domain consisting in the negative ones has not been clearly evidenced in this study. The limited practical use of the conditional dimensions Employment Concerns and Relationship Concerns, whether the patient is partnered or not, did not make possible to provide evidence of validity and reliability of these dimensions as the subsets of sample to work with were not large enough. The scores of these conditional dimensions have to be used with full knowledge of the facts of this limitation of the study. Integrating IOCv2 into studies will contribute to evaluate the psychosocial health experience of the growing population of cancer survivors, enabling better understanding of the multi-dimensional impact of cancer.

The Computer Adaptive Test version of the Community Reintegration of Injured Service Members measure (CRIS-CAT) consists of three scales measuring Extent of, Perceived Limitations in, and Satisfaction with community integration. The CRIS-CAT was developed using item response theory methods. The purposes of this study were to assess the reliability, concurrent, known group and predictive validity and respondent burden of the CRIS-CAT.The CRIS-CAT was developed using item response theory methods. The purposes of this study were to assess the reliability, concurrent, known group and predictive validity and respondent burden of the CRIS-CAT. This was a three-part study that included a 1) a cross-sectional field study of 517 homeless, employed, and Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans; who completed all items in the CRIS item set, 2) a cohort study with one year follow-up study of 135 OEF/OIF Veterans, and 3) a 50-person study of CRIS-CAT administration. Conditional reliability of simulated CAT scores was calculated from the field study data, and concurrent validity and known group validity were examined using Pearson product correlations and ANOVAs. Data from the cohort were used to examine the ability of the CRIS-CAT to predict key one year outcomes. Data from the CRIS-CAT administration study were used to calculate ICC (2,1) minimum detectable change (MDC), and average number of items used during CAT administration. Reliability scores for all scales were above 0.75, but decreased at both ends of the score continuum. CRIS-CAT scores were correlated with concurrent validity indicators and differed significantly between the three Veteran groups (P < .001). The odds of having any Emergency Room visits were reduced for Veterans with better CRIS-CAT scores (Extent, Perceived Satisfaction respectively: OR = 0.94, 0.93, 0.95; P < .05). CRIS-CAT scores were predictive of SF-12 physical and mental health related quality of life scores at the 1 year follow-up. Scales had ICCs >0.9. MDCs were 5.9, 6.2, and 3.6, respectively for Extent, Perceived and Satisfaction subscales. Number of items (mn, SD) administered at Visit 1 were 14.6 (3.8) 10.9 (2.7) and 10.4 (1.7) respectively for Extent, Perceived and Satisfaction subscales. The CRIS-CAT demonstrated sound measurement properties including reliability, construct, known group and predictive validity, and it was administered with minimal respondent burden. These findings support the use of this measure in assessing community reintegration.

The aim of this study was the validation of a brief form of the Perceived Neighborhood Social Cohesion questionnaire using data from 5065 men from the "Cohort Study on Substance-Use Risk Factors." A 9-item scale covering three factors was proposed. Excellent indices of internal consistency were measured (α = .93). The confirmatory factor analyses resulted in acceptable fit indices supporting measurement invariance across French and German forms. Significant correlations were found between the brief form of the Perceived Neighborhood Social Cohesion questionnaire, and satisfaction and self-reported health, providing evidence of the concurrent validity of the scale. Perceived neighborhood social cohesion, and depression and suicide attempts were negatively associated, sustaining the protective effect of perceived social cohesion.

The carer history is an integral part of the assessment of patients with cognitive impairment. We aimed to develop a comprehensive yet concise carer questionnaire, the CogRisk, which captures actuarial risk variables for cognitive impairment in addition to key symptoms suggestive of cognitive decline in a number of cognitive domains, and to then assess its validity and reliability in a neuropsychiatric population. Carers of patients assessed for cognitive impairment completed the CogRisk, and patients were clinically assessed using the Mini-Mental State Examination (MMSE) and Neuropsychiatry Unit COGnitive assessment tool (NUCOG). Reliability was assessed using test-retest and interrater measures and measures of internal consistency. Construct and concurrent validity was assessed using correlation between total and subscale scores on the CogRisk, total scores on the NUCOG and MMSE, and subscale scores on the NUCOG. Predictive validity was determined using measures of sensitivity and specificity and using receiver operating characteristic (ROC) methods. The CogRisk was completed by all carers in less than 10 min. The total CogRisk score correlated significantly with total MMSE and NUCOG scores (r=-0.511 and -0.563, respectively) and remained highly significant when age and education were controlled for. Internal consistency of CogRisk items was high (alpha=0.943). Intrarater reliability of the CogRisk was high with an intraclass correlation coefficient of .978 (P<.001), and interrater reliability between carers was also high at 0.868 (P<.05). Sensitivity and specificity for the detection of dementia were .70 and .73, respectively, with area under the ROC curve not significantly different from that of the MMSE or NUCOG. The CogRisk is a brief carer-rated tool of a patient's cognitive functioning developed for use within a neuropsychiatric setting. It exhibited good concurrent validity, internal consistency, and interrater and intrarater reliability. The CogRisk also demonstrated good sensitivity and specificity for dementia. The CogRisk provides carer information, which complements the clinical assessment and can be used to focus on direct carer interview.

Latency-Based and Psychophysiological Measures of Sexual Interest Show Convergent and Concurrent Validity.

Latency-based measures of sexual interest require additional evidence of validity, as do newer pupil dilation approaches. A total of 102 community men completed six latency-based measures of sexual interest. Pupillary responses were recorded during three of these tasks and in an additional task where no participant response was required. For adult stimuli, there was a high degree of intercorrelation between measures, suggesting that tasks may be measuring the same underlying construct (convergent validity). In addition to being correlated with one another, measures also predicted participants' self-reported sexual interest, demonstrating concurrent validity (i.e., the ability of a task to predict a more validated, simultaneously recorded, measure). Latency-based and pupillometric approaches also showed preliminary evidence of concurrent validity in predicting both self-reported interest in child molestation and viewing pornographic material containing children. Taken together, the study findings build on the evidence base for the validity of latency-based and pupillometric measures of sexual interest.

This exploratory, descriptive, cross-sectional, and quantitative study aimed to develop and validate an index of family vulnerability to disability and dependence (FVI-DD). This study was adapted from the Family Development Index, with the addition of social and health indicators of disability and dependence. The instrument was applied to 248 families in the city of Sao Paulo, followed by exploratory factor analysis. Factor validation was performed using the concurrent and discriminant validity of the Lawton scale and Katz Index. The descriptive level adopted for the study was p < 0.05. The final vulnerability index comprised 50 questions classified into seven factors contemplating social and health dimensions, and this index exhibited good internal consistency (Cronbach's alpha = 0.82). FVI-DD was validated using both the Lawton scale and Katz Index. We conclude that FVI-DD can accurately and reliably assess family vulnerability to disability and dependence.

The purpose of this study was to examine the psychometric properties of Thai versions of the Maternal Behavior Q-Sort (MBQS), Caldwell's HOME, and the Attachment Q-set (AQS). A sample of 110 Thai mother-infant dyads were studied. The Content Validity Index (CVIs) of the Thai MBQS, HOME and AQS were between 91% and 99%. Internal consistency of the HOME was .71. Interobserver reliability of the MBQS, HOME, and AQS were .95, .87, and .87, respectively. Convergent validity was supported by finding a positive correlation between the MBQS and the HOME (r = .29, p < .001). A positive correlation of .45 (p < .001) between the scores of the MBQS and the AQS indicated concurrent validity of these scales. Study findings indicate the Thai MBQS, HOME, and AQS are reliable and valid in this Thai sample and suggest that the Thai versions reflect concepts similar to those in the original English versions.

In the present study, we examined the psychometric properties of the Skin Picking Impact Scale (SPIS; Keuthen, Deckersbach, Wilhelm et al., 2001), a 10 item self-report questionnaire designed to assess the psychosocial impact of skin picking disorder (SPD). Participants were 650 individuals who met criteria for SPD in an online survey. Exploratory and confirmatory factor analyses demonstrated a unitary factor structure with high internal consistency (α = 0.94). Consequently, we constructed an abbreviated 4-item version that retained good internal consistency (α = 0.87) and a robust factor structure. Both the short and the full versions demonstrated discriminant and convergent/concurrent validity. In conclusion, the findings indicate that both versions are psychometrically sound measures of SPD related psychosocial impact; however, some potential limitations of the full scale are discussed. © 2013 The Scandinavian Psychological Associations.

Background and Purpose Type 2 diabetes mellitus (T2DM) self-management among Hispanic adults occurs in a family context. Self-efficacy (SE) affects T2DM self-management behaviors; however, no instruments are available to measure family diabetes self-efficacy. The study’s purpose was to test the psychometric properties of the Family Self-Efficacy for Diabetes Scale (FSE). Methods Family members (n = 113) of adults with T2DM participated. Psychometric analysis included internal consistency reliability and concurrent and construct validity. Results Internal consistency reliability was .86. Items loaded on 2 factors, Family SE for Supporting Healthy Behaviors and Family SE for Supporting General Health, accounting for 71% of the variance. FSE correlated significantly with 3 diabetes-related instruments. Conclusions The FSE is a reliable and valid instrument. Further testing is needed in diverse populations and geographic areas.

We explored the concurrent validity of the MMPI-2 Low Self-Esteem (LSE) Content scale by asking 216 undergraduate students to complete the Minnesota Multiphasic Personality Inventory-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1991), Harter Adult Self-Perception Profile (Harter, 1986a) and Rosenberg Self-Esteem Scale (Rosenberg, 1965). Results suggest the LSE renders a good assessment of global self-esteem as well as being a measure of three distinct components of self-esteem. These specific subscales, identified by factor analysis, were labeled Ineptitude, Negative Self-Value, and Negative Comparison with Others. The LSE and its subscales produced good internal consistency (alpha and Gutman Split Half) coefficients.

The objectives of this study were to develop a unified Portuguese-language version, for use in Brazil and Portugal, of the Body Shape Questionnaire (BSQ) and to estimate its validity, reliability, and internal consistency in Brazilian and Portuguese female university students. Confirmatory factor analysis was performed using both original (34-item) and shortened (8-item) versions. The model's fit was assessed with χ²/df, CFI, NFI, and RMSEA. Concurrent and convergent validity were assessed. Reliability was estimated through internal consistency and composite reliability (α). Transnational invariance of the BSQ was tested using multi-group analysis. The original 32-item model was refined to present a better fit and adequate validity and reliability. The shortened model was stable in both independent samples and in transnational samples (Brazil and Portugal). The use of this unified version is recommended for the assessment of body shape concerns in both Brazilian and Portuguese college students.

The Occupational Fatigue Exhaustion/Recovery Scale (OFER) was designed to assess occupational fatigue in nurses. Although the original English version of this instrument has shown high degrees of reliability and validity, a Chinese version of this scale has yet to be verified. The aim of this study was to evaluate the psychometric properties of the OFER in a population of Chinese nurses. The scale was translated using translation and back-translation. The validities and reliabilities were evaluated on 923 qualified participants using content validity index, concurrent validity, factorial validity, internal consistency reliability, and test-retest reliability. The content validity index for the OFER was .92. The correlation coefficients between the scores of the OFER subscales and the criteria in this study (varying from -.498 to .705) verified that the OFER has acceptable concurrent validity. Principal component analysis and confirmatory factor analysis revealed that three factors correspond to the structure of the original instrument and that recovery mediates the relationship between acute and chronic fatigue. The Cronbach's alpha for the chronic fatigue, acute fatigue, and intershift recovery subscales were .83, .85, and .86, respectively. Test-retest reliabilities with correlation coefficients from .61 to .78 were found in the three subscales. OFER is a reliable and valid instrument for assessing work-related fatigue in Chinese nurses. However, further improvement of the acute fatigue subscale is recommended. The OFER has the potential to elicit information that is useful for assessing fatigue in nurses in China. Furthermore, as it differentiates between acute and chronic fatigue, OFER may be an effective tool for guiding the development and implementation of various, related intervention measures.

To translate the Tilburg Frailty Indicator (TFI) into Chinese and assess its reliability and validity. A sample of 917 community-dwelling older people, aged ≥60 years, in a Chinese city was included between August 2015 and March 2016. Construct validity was assessed using alternative measures corresponding to the TFI items, including self-rated health status (SRH), unintentional weight loss, walking speed, timed-up-and-go tests (TUGT), making telephone calls, grip strength, exhaustion, Short Portable Mental Status Questionnaire (SPMSQ), Geriatric Depression scale (GDS-15), emotional role, Adaptability Partnership Growth Affection and Resolve scale (APGAR) and Social Support Rating Scale (SSRS). Fried's phenotype and frailty index were measured to evaluate criterion validity. Adverse health outcomes (ADL and IADL disability, healthcare utilization, GDS-15, SSRS) were used to assess predictive (concurrent) validity. The internal consistency reliability was good (Cronbach's α=0.71). The test-retest reliability was strong (r=0.88). Kappa coefficients showed agreements between the TFI items and corresponding alternative measures. Alternative measures correlated as expected with the three domains of TFI, with an exclusion that alternative psychological measures had similar correlations with psychological and physical domains of the TFI. The Chinese TFI had excellent criterion validity with the AUCs regarding physical phenotype and frailty index of 0.87 and 0.86, respectively. The predictive (concurrent) validities of the adverse health outcomes and healthcare utilization were acceptable (AUCs: 0.65-0.83). The Chinese TFI has good validity and reliability as an integral instrument to measure frailty of older people living in the community in China. Copyright © 2017 Elsevier B.V. All rights reserved.

This study reports the psychometric validation of a new HIV/AIDS-specific health-related quality of life (HRQL) questionnaire, the Patient Reported Outcomes Quality of Life-HIV. The instrument was developed simultaneously across Europe, North and South America, Africa, Asia, and Australia to assess multidimensional quality of life impairments in the era of highly active antiretroviral therapy. A cross-sectional study was performed in 8 countries. The pilot 70-item questionnaire was co-administered with the HIV symptoms index, the EQ-5D and Medical Outcomes Study-HIV questionnaires. Demographic and biomedical data were collected. After item analysis and reduction, convergent discriminant concurrent validity and known-group validity were examined. Internal consistency and reliability scores were assessed using Cronbach alpha and intraclass correlation. The final sample of 791 patients was composed of 64% males (median age: 41 years, HIV diagnosis = 5 years), 13.8% were treatment naive. Item reduction yielded a 43-item form surveying 8 dimensions and 1 global health item that showed good convergent and discriminant validity and reliability (98% scaling success; Cronbach alphas 0.77-0.89). Correlations with EQ-5D and Medical Outcomes Study-HIV complied with concurrent validity expectations; likewise, correlations against the number of self-reported symptoms and depression showed good support for criterion validity. A test-retest study on French patients (n = 34) showed temporal stability (intraclass correlation coefficient = 0.86). Significant and meaningful differences of HRQL scores between countries were found. The Patient Reported Outcomes Quality of Life-HIV questionnaire is a valid and reliable instrument for assessing HRQL specific to HIV disease in different cultures and healthcare systems.

Among current early screeners for psychosis-risk states, the Prodromal Questionnaire-16 items (PQ-16) is often used. We aimed to assess validity and reliability of the Italian version of the PQ-16 in a young adult help-seeking population. We included 154 individuals aged 18-35years seeking help at the Reggio Emilia outpatient mental health services in a large semirural catchment area (550.000 inhabitants). Participants completed the Italian version of the PQ-16 (iPQ-16) and were subsequently evaluated with the Comprehensive Assessment of At-Risk Mental States (CAARMS). We examined diagnostic accuracy (i.e. specificity, sensitivity, negative and positive likelihood ratios, and negative and positive predictive values) and content, convergent, and concurrent validity between PQ-16 and CAARMS using Cronbach's alpha, Spearman's rho, and Cohen's kappa, respectively. We also tested the validity of the adopted PQ-16 cut-offs through Receiver Operating Characteristic (ROC) curves plotted against CAARMS diagnoses and the 1-year predictive validity of the PQ-16. The iPQ-16 showed high internal consistency and acceptable diagnostic accuracy and concurrent validity. ROC analyses pointed to a cut-off score of ≥5 as best cut-off. After 12months of follow-up, 8.7% of participants with a PQ-16 symptom total score of ≥5 who were below the CAARMS psychosis threshold at the baseline, developed a psychotic disorder. Psychometric properties of the iPQ-16 were satisfactory. Copyright © 2018. Published by Elsevier B.V.

A valid, time-efficient and easy-to-use instrument is important for busy clinical settings, large scale surveys, or community screening use. The purpose of this study was to validate the mobility hierarchical disability categorization model (an abbreviated model) by investigating its concurrent validity with the multidimensional hierarchical disability categorization model (a comprehensive model) and triangulating both models with physical performance measures in older adults. 604 community-dwelling older adults of at least 60 years in age volunteered to participate. Self-reported function on mobility, instrumental activities of daily living (IADL) and activities of daily living (ADL) domains were recorded and then the disability status determined based on both the multidimensional hierarchical categorization model and the mobility hierarchical categorization model. The physical performance measures, consisting of grip strength and usual and fastest gait speeds (UGS, FGS), were collected on the same day. Both categorization models showed high correlation (γs = 0.92, p < 0.001) and agreement (kappa = 0.61, p < 0.0001). Physical performance measures demonstrated significant different group means among the disability subgroups based on both categorization models. The results of multiple regression analysis indicated that both models individually explain similar amount of variance on all physical performances, with adjustments for age, sex, and number of comorbidities. Our results found that the mobility hierarchical disability categorization model is a valid and time efficient tool for large survey or screening use.

Observer OPTION(5) was designed as a more efficient version of OPTION(12), the most commonly used measure of shared decision making (SDM). The current paper assesses the psychometric properties of OPTION(5). Two raters used OPTION(5) to rate recordings of clinical encounters from two previous patient decision aid (PDA) trials (n=201; n=110). A subsample was re-rated two weeks later. We assessed discriminative validity, inter-rater reliability, intra-rater reliability, and concurrent validity. OPTION(5) demonstrated discriminative validity, with increases in SDM between usual care and PDA arms. OPTION(5) also demonstrated concurrent validity with OPTION(12), r=0.61 (95%CI 0.54, 0.68) and intra-rater reliability, r=0.93 (0.83, 0.97). The mean difference in rater score was 8.89 (95% Credibility Interval, 7.5, 10.3), with intraclass correlation (ICC) of 0.67 (95% Credibility Interval, 0.51, 0.91) for the accuracy of rater scores and 0.70 (95% Credibility Interval, 0.56, 0.94) for the consistency of rater scores across encounters, indicating good inter-rater reliability. Raters reported lower cognitive burden when using OPTION(5) compared to OPTION(12). OPTION(5) is a brief, theoretically grounded observer measure of SDM with promising psychometric properties in this sample and low burden on raters. OPTION(5) has potential to provide reliable, valid assessment of SDM in clinical encounters. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Few psychometric studies of the Hospital Anxiety and Depression Scale (HADS) scale have been performed with clinical samples of elderly individuals. The participants were 484 elderly (65-101 years, 241 men) patients in an acute medical unit. The HADS, the Montgomery-Aasberg Depression Rating Scale (MADRS) and questionnaires assessing quality of life, functional impairment, and cognitive function were used. The psychometric evaluation of the HADS included the following analyses: 1) the internal construct validity by means of principal component analysis followed by an oblique rotation and corrected item-total correlation; 2) the internal consistency reliability by means of the alpha coefficient (Cronbach's) and 3) concurrent validity by means of Spearman's rho. We found a two-factor solution explaining 45% of the variance. Six of seven items loaded adequately (≥0.40) on the HADS-A subscale (item 7 did not) and five of seven items loaded adequately on the HADS-D subscale (items 8 and 10 did not). Cronbach's alpha for the HADS-A and HADS-D subscale was 0.78 and 0.71, respectively. The correlation between HADS-D and the MADRS, a measure of the concurrent validity, was 0.51. The HADS appears to differentiate well between depression and anxiety. The internal consistency of the HADS in a sample of elderly persons was as satisfactory as it is in samples with younger persons. In contrast to younger samples, item 8 ("I feel as if I have slowed down") did not load adequately on the HADS-D subscale. This may be attributed to the way elderly people experience and describe their symptoms.

Prediction models and prognostic scores have been increasingly popular in both clinical practice and clinical research settings, for example to aid in risk-based decision making or control for confounding. In many medical fields, a large number of prognostic scores are available, but practitioners may find it difficult to choose between them due to lack of external validation as well as lack of comparisons between them. Borrowing methodology from network meta-analysis, we describe an approach to Multiple Score Comparison meta-analysis (MSC) which permits concurrent external validation and comparisons of prognostic scores using individual patient data (IPD) arising from a large-scale international collaboration. We describe the challenges in adapting network meta-analysis to the MSC setting, for instance the need to explicitly include correlations between the scores on a cohort level, and how to deal with many multi-score studies. We propose first using IPD to make cohort-level aggregate discrimination or calibration scores, comparing all to a common comparator. Then, standard network meta-analysis techniques can be applied, taking care to consider correlation structures in cohorts with multiple scores. Transitivity, consistency and heterogeneity are also examined. We provide a clinical application, comparing prognostic scores for 3-year mortality in patients with chronic obstructive pulmonary disease using data from a large-scale collaborative initiative. We focus on the discriminative properties of the prognostic scores. Our results show clear differences in performance, with ADO and eBODE showing higher discrimination with respect to mortality than other considered scores. The assumptions of transitivity and local and global consistency were not violated. Heterogeneity was small. We applied a network meta-analytic methodology to externally validate and concurrently compare the prognostic properties of clinical scores. Our large-scale external validation indicates that the scores with the best discriminative properties to predict 3 year mortality in patients with COPD are ADO and eBODE.

Active aging is central to enhancing the quality of life for older adults, but its conceptualization is not often made explicit for Asian elderly people. Little is known about active aging in older Thai adults, and there has been no development of scales to measure the expression of active aging attributes. The aim of this study was to develop a culturally relevant composite scale of active aging for Thai adults (AAS-Thai) and to evaluate its reliability and validity. EIGHT STEPS OF SCALE DEVELOPMENT WERE FOLLOWED: 1) using focus groups and in-depth interviews, 2) gathering input from existing studies, 3) developing preliminary quantitative measures, 4) reviewing for content validity by an expert panel, 5) conducting cognitive interviews, 6) pilot testing, 7) performing a nationwide survey, and 8) testing psychometric properties. In a nationwide survey, 500 subjects were randomly recruited using a stratified sampling technique. Statistical analyses included exploratory factor analysis, item analysis, and measures of internal consistency, concurrent validity, and test-retest reliability. Principal component factor analysis with varimax rotation resulted in a final 36-item scale consisting of seven factors of active aging: 1) being self-reliant, 2) being actively engaged with society, 3) developing spiritual wisdom, 4) building up financial security, 5) maintaining a healthy lifestyle, 6) engaging in active learning, and 7) strengthening family ties to ensure care in later life. These factors explained 69% of the total variance. Cronbach's alpha coefficient for the overall AAS-Thai was 0.95 and varied between 0.81 and 0.91 for the seven subscales. Concurrent validity and test-retest reliability were confirmed. The AAS-Thai demonstrated acceptable overall validity and reliability for measuring the multidimensional attributes of active aging in a Thai context. This newly developed instrument is ready for use as a screening tool to assess active aging levels among older Thai adults in both community and clinical practice settings.

This study aimed to analyze the reliability and validity of the Spanish version of the Medical Outcomes Study Sleep Scale (MOS-SS), and its ability to discriminate between poor and good sleepers among a Spanish population with vestibular disorders. In all, 121 women (50-76 years old) completed the Spanish version of the MOS-SS. Internal consistency, test-retest reliability, and construct validity (exploratory factor analysis) were analyzed. Concurrent validity was evaluated using the Pittsburgh Sleep Quality Index and the 36-item Short Form Health Survey. To analyze the ability of the MOS-SS scores to discriminate between poor and good sleepers, a receiver-operating characteristic curve analysis was performed. The Spanish version of the MOS-SS showed excellent and substantial reliability in Sleep Problems Index I (two sleep disturbance items, one somnolence item, two sleep adequacy items, and awaken short of breath or with headache) and Sleep Problems Index II (four sleep disturbance items, two somnolence items, two sleep adequacy items, and awaken short of breath or with headache), respectively, and good internal consistency with optimal Cronbach's alpha values in all domains and indexes (0.70-0.90). Factor analysis suggested a coherent four-factor structure (explained variance 70%). In concurrent validity analysis, MOS-SS indexes showed significant and strong correlation with the Pittsburgh Sleep Quality Index total score, and moderate with the 36-item Short Form Health Survey component summaries. Several domains and the two indexes were significantly able to discriminate between poor and good sleepers (P < 0.05). Optimal cut-off points were above 20 for "sleep disturbance" domain, with above 22.22 and above 33.33 for Sleep Problems Index I and II. The Spanish version of the MOS-SS is a valid and reliable instrument, suitable to assess sleep quality in Spanish postmenopausal women, with satisfactory general psychometric properties. It discriminates well between good and poor sleepers.

Drive for Muscularity (DM) has been shown to be a relevant construct for measuring and understanding male body image. For this reason, it is important to have reliable and valid instruments with which to measure DM, and to date no such instruments exist in Spain. This study analyzes the psychometric and structural properties of the Drive for Muscularity Scale (DMS) in a sample of Spanish adolescent males (N=212), with the aim of studying the structural validity of the scale by using a confirmatory factor analysis (CFA), as well as analyzing the internal consistency and construct (convergent and discriminant) and concurrent validity of the instrument. After testing three models, results indicated that the best structure was a two-dimensional model, with the factors of muscularity-oriented body image (MBI) and muscularity behavior (MB). The scale showed good internal consistency (α=.90) and adequate construct validity. Furthermore, significant associations were found between DM and increased difficulties in emotional regulation (rho=.37) and low self-esteem (rho=-.19). Findings suggest that the two-factor structure may be used when assessing drive for muscularity among adolescent males in Spain. Copyright © 2016 Elsevier Ltd. All rights reserved.

We developed a Korean translation of the Internet Addiction Test (KIAT), widely used self-report for internet addiction and tested its reliability and validity in a sample of college students. Two hundred seventy-nine college students at a national university completed the KIAT. Internal consistency and two week test-retest reliability were calculated from the data, and principal component factor analysis was conducted. Participants also completed the Internet Addiction Diagnostic Questionnaire (IADQ), the Korea Internet addiction scale (K-scale), and the Patient Health Questionnaire-9 for the criterion validity. Cronbach's alpha of the whole scale was 0.91, and test-retest reliability was also good (r = 0.73). The IADQ, the K-scale, and depressive symptoms were significantly correlated with the KIAT scores, demonstrating concurrent and convergent validity. The factor analysis extracted four factors (Excessive use, Dependence, Withdrawal, and Avoidance of reality) that accounted for 59% of total variance. The KIAT has outstanding internal consistency and high test-retest reliability. Also, the factor structure and validity data show that the KIAT is comparable to the original version. Thus, the KIAT is a psychometrically sound tool for assessing internet addiction in the Korean-speaking population. PMID:23678270

There is a paucity of screening instruments with a high clinical predictive value to identify families at risk and therefore, develop focused interventions in primary care. To develop an easy to apply screening instrument with a high clinical predictive value to identify families with a higher health vulnerability. In the first stage of the study an instrument with a high content validity was designed through a review of existent instruments, qualitative interviews with families and expert opinions following a Delphi approach of three rounds. In the second stage, concurrent validity was tested through a comparative analysis between the pilot instrument and a family clinical interview conducted to 300 families randomly selected from a population registered at a primary care clinic in Santiago. The sampling was blocked based on the presence of diabetes, depression, child asthma, behavioral disorders, presence of an older person or the lack of previous conditions among family members. The third stage, was directed to test the clinical predictive validity of the instrument by comparing the baseline vulnerability obtained by the instrument and the change in clinical status and health related quality of life perceptions of the family members after nine months of follow-up. The final SALUFAM instrument included 13 items and had a high internal consistency (Cronbach's alpha: 0.821), high test re-test reproducibility (Pearson correlation: 0.84) and a high clinical predictive value for clinical deterioration (Odds ratio: 1.826; 95% confidence intervals: 1.101-3.029). SALUFAM instrument is applicable, replicable, has a high content validity, concurrent validity and clinical predictive value.

Motor disturbances and disturbed self-recognition are common features that affect mobility in persons with schizophrenia spectrum disorder and bipolar disorder. Physiotherapists in Scandinavia assess and treat movement difficulties in persons with severe mental illness. The Body Awareness Scale Movement Quality and Experience (BAS MQ-E) is a new and shortened version of the commonly used Body Awareness Scale-Health (BAS-H). The purpose of this study was to investigate the inter-rater reliability and the concurrent validity of BAS MQ-E in persons with severe mental illness. The concurrent validity was examined by investigating the relationships between neurological soft signs, alexithymia, fatigue, anxiety, and mastery. Sixty-two persons with severe mental illness participated in the study. The results showed a satisfactory inter-rater reliability (n = 53) and a concurrent validity (n = 62) with neurological soft signs, especially cognitive and perceptual based signs. There was also a concurrent validity linked to physical fatigue and aspects of alexithymia. The scores of BAS MQ-E were in general higher for persons with schizophrenia compared to persons with other diagnoses within the schizophrenia spectrum disorders and bipolar disorder. The clinical implications are presented in the discussion.

We sought to evaluate the Balance Outcome Measure for Elder Rehabilitation (BOOMER) in community-dwelling women 65 years and older with vertebral fracture and to describe score distributions and potential ceiling and floor effects. This was a secondary data analysis of baseline data from the Build Better Bones with Exercise randomized controlled trial using the BOOMER. A total of 141 women with osteoporosis and radiographically confirmed vertebral fracture were included. Concurrent validity and internal consistency were assessed in comparison to the Short Physical Performance Battery (SPPB). Normality and ceiling/floor effects of total BOOMER scores and component test items were also assessed. Exploratory analyses of assistive aid use and falls history were performed. Tests for concurrent validity demonstrated moderate correlation between total BOOMER and SPPB scores. The BOOMER component tests showed modest internal consistency. Substantial ceiling effect and nonnormal score distributions were present among overall sample and those not using assistive aids for total BOOMER scores, although scores were normally distributed for those using assistive aids. The static standing with eyes closed test demonstrated the greatest ceiling effects of the component tests, with 92% of participants achieving a maximal score. While the BOOMER compares well with the SPPB in community-dwelling women with vertebral fractures, researchers or clinicians considering using the BOOMER in similar or higher-functioning populations should be aware of the potential for ceiling effects.

To translate the Dementia quality of life instrument (DQoL) into German and assess its construct and concurrent validity in community-dwelling people with mild to moderate dementia. Dementia quality of life instrument data of two pooled samples (n=287) were analysed regarding ceiling and floor effects, internal consistency, factor reliability and correlations with corresponding scales on quality of life (Quality of Life in Alzheimer's Disease and SF-12), cognition (Mini-Mental State Examination, Alzheimer's Disease Assessment Scale - cognitive), depression (Cornell Scale for Depression in Dementia) and activities of daily living (Interview of Deterioration in Daily Living Activities in Dementia). We found no floor effects (<2%), minor ceiling effects (1-11%), moderate to good internal consistency (Cronbach's α: 0.6-0.8) and factor reliability (0.6-0.8), moderate correlations with self-rated scales of quality of life (Spearman coefficient: 0.3-0.6) and no or minor correlations with scores for cognition, depression or activities of daily living (r<0.3). The original five-factor model could not be confirmed. The DQoL can be used in dementia research for assessing positive and negative affect, feelings of belonging and self-esteem. The findings suggest further research to improve the structure of the scales aesthetics, feelings of belonging and self-esteem. © 2011 The Author(s). European Journal of Neurology © 2011 EFNS.

This study examined the psychometric properties of two versions of a commonly used physical activity 7-d self-report, the Physical Activity Questionnaire for Older Children (PAQ-C) and Physical Activity Questionnaire for Adolescents (PAQ-A). We longitudinally examined the internal consistency, stability, and situational effects of the PAQ-C and PAQ-A in a cohort of children (N = 210) at ages 11 and 13 yr. Statistical analysis included factor loading and standardized Cronbach coefficient alphas. We cross-sectionally examined concurrent validity of the PAQ-A in a subsample of our cohort (N = 49) at age 13 by comparing it with concurrently measured physical activity using an activity monitor (Actigraph). Spearman correlation coefficients were used for this analysis. Standardized Cronbach alphas ranged from 0.72 to 0.88. A subsample analysis suggested that completing the questionnaires during the summer months slightly reduced the standardized alpha for the PAQ-C, but not the PAQ-A. Associations between the PAQ-A (revised) summary score and activity monitor variables were rho = 0.56 for total PA and rho = 0.63 for moderate through vigorous activity (P < 0.05). Associations between individual PAQ-A questions and activity monitor variables for the same time frame ranged from rho = 0.41 to 0.62 (P < 0.05). The PAQ-C and PAQ-A show good internal consistency. The PAQ-A has acceptable validity.

Pressure ulcer prevention is an important long-term care (LTC) quality indicator. While the Braden Scale is a recommended risk assessment tool, there is a paucity of information specifically pertaining to its validity within the LTC setting. We, therefore, undertook a systematic review and meta-analysis comparing Braden Scale predictive and concurrent validity within this context. We searched the Medline, EMBASE, PsychINFO and PubMed databases from 1985-2014 for studies containing the requisite information to analyze tool validity. Our initial search yielded 3,773 articles. Eleven datasets emanating from nine published studies describing 40,361 residents met all meta-analysis inclusion criteria and were analyzed using random effects models. Pooled sensitivity, specificity, positive predictive value (PPV), and negative predictive values were 86%, 38%, 28%, and 93%, respectively. Specificity was poorer in concurrent samples as compared with predictive samples (38% vs. 72%), while PPV was low in both sample types (25 and 37%). Though random effects model results showed that the Scale had good overall predictive ability [RR, 4.33; 95% CI, 3.28-5.72], none of the concurrent samples were found to have "optimal" sensitivity and specificity. In conclusion, the appropriateness of the Braden Scale in LTC is questionable given its low specificity and PPV, in particular in concurrent validity studies. Future studies should further explore the extent to which the apparent low validity of the Scale in LTC is due to the choice of cutoff point and/or preventive strategies implemented by LTC staff as a matter of course. © 2015 by the Wound Healing Society.

SUMMARY Objective To summarize literature on the concurrent and predictive validity of MRI-based measures of osteoarthritis (OA) structural change. Methods An online literature search was conducted of the OVID, EMBASE, CINAHL, PsychInfo and Cochrane databases of articles published up to the time of the search, April 2009. 1338 abstracts obtained with this search were preliminarily screened for relevance by two reviewers. Of these, 243 were selected for data extraction for this analysis on validity as well as separate reviews on discriminate validity and diagnostic performance. Of these 142 manuscripts included data pertinent to concurrent validity and 61 manuscripts for the predictive validity review. For this analysis we extracted data on criterion (concurrent and predictive) validity from both longitudinal and cross-sectional studies for all synovial joint tissues as it relates to MRI measurement in OA. Results Concurrent validity of MRI in OA has been examined compared to symptoms, radiography, histology/pathology, arthroscopy, CT, and alignment. The relation of bone marrow lesions, synovitis and effusion to pain was moderate to strong. There was a weak or no relation of cartilage morphology or meniscal tears to pain. The relation of cartilage morphology to radiographic OA and radiographic joint space was inconsistent. There was a higher frequency of meniscal tears, synovitis and other features in persons with radiographic OA. The relation of cartilage to other constructs including histology and arthroscopy was stronger. Predictive validity of MRI in OA has been examined for ability to predict total knee replacement (TKR), change in symptoms, radiographic progression as well as MRI progression. Quantitative cartilage volume change and presence of cartilage defects or bone marrow lesions are potential predictors of TKR. Conclusion MRI has inherent strengths and unique advantages in its ability to visualize multiple individual tissue pathologies relating to pain and also predict clinical outcome. The complex disease of OA which involves an array of tissue abnormalities is best imaged using this imaging tool. PMID:21396463

Abstract The aim of this study was to evaluate the psychometric properties of the Problematic Mobile Phone Use Scale (PMPUS) for Turkish Adolescents. The psychometric properties of PMPUS were tested in two separate sample groups that consisted of 950 Turkish high school students. The first sample group (n=309) was used to determine the factor structure of the scale. The second sample group (n=461) was used to test data conformity with the identified structure, discriminant validity and concurrent scale validity, internal consistency reliability calculations, and item statistics calculations. The results of exploratory factor analyses indicated that the scale had three factors: interference with negative effect, compulsion/persistence, and withdrawal/tolerance. The results showed that item and construct reliability values yielded satisfactory rates in general for the three-factor construct. On the other hand, the average variance extracted value remained below the scale value for three subscales. The scores for the scale significantly correlated with depression and loneliness. In addition, the discriminant validity value was above the scale in all sub-dimensions except one. Based on these data, the reliability of the PMPUS scale appears to be satisfactory and provides good internal consistency. Therefore, with limited exception, the PMPUS was found to be reliable and valid in the context of Turkish adolescents.

To analyze the reliability and validity of the Spanish version of the OSA-18 quality of life questionnaire in children with apnea-hypopnea syndrome (SAHS). Children with suspected SAHS were studied with polysomnography (PSG) before and after adenotonsillectomy (AA). Age, gender, clinical data, PSG, anthropometric data, and Mallampati and Brodsky scales were analyzed. OSA-18 was administered at baseline and 3-6months post AA. After translation and backtranslation by bilingual professionals, the internal consistency, reliability, construct validity, concurrent validity, predictive validity and sensitivity to change of the questionnaire was assessed. In total, 45 boys and 15 girls were evaluated, showing BMI 18±4, neck 28±5, Brodsky (0: 7%; <25%: 12%; 25-50%: 27%; >50 to <75%: 45%; >75%: 6%), AHI 12±7 pre AA. Global Cronbach alpha was 0.91. Correlations between domains were significant except for emotional aspects, although the total scores correlated with all domains (0.50 to 0.90). The factorial analysis was virtually identical to the original structure. The total scores showed good correlation for concurrent validity (0.2-0.45). With regard to predictive validity, the questionnaire adequately differentiated levels of severity according to Mallampati (ANOVA P=.002) and apnea-hypopnea index (ANOVA P=.006). Test-retest reliability was excellent, as was sensitivity to change, both in the total scores (P<.001) and in each domain (P<.001). The Spanish adaptation of the OSA-18 and its psychometric characteristics suggest that the Spanish version is equivalent to the original and can be used in Spanish-speaking countries.

2009-01-01

This paper describes the inter-rater and intra-rater reliability, and the concurrent validity of an observational instrument, the Keyboard Personal Computer Style instrument (K-PeCS), which assesses stereotypical postures and movements associated with computer keyboard use. Three trained raters independently rated the video clips of 45 computer keyboard users to ascertain inter-rater reliability, and then re-rated a sub-sample of 15 video clips to ascertain intra-rater reliability. Concurrent validity was assessed by comparing the ratings obtained using the K-PeCS to scores developed from a 3D motion analysis system. The overall K-PeCS had excellent reliability [inter-rater: intra-class correlation coefficients (ICC)=.90; intra-rater: ICC=.92]. Most individual items on the K-PeCS had from good to excellent reliability, although six items fell below ICC=.75. Those K-PeCS items that were assessed for concurrent validity compared favorably to the motion analysis data for all but two items. These results suggest that most items on the K-PeCS can be used to reliably document computer keyboarding style.

2017-08-01

The goal of this research project was to develop a new questionnaire to assess resilience in Bipolar Disorder (BD), the Resilience Questionnaire for Bipolar Disorder (RBD). To examine its psychometric properties, a sample of 125 patients diagnosed with BD and a comparison sample of 107 people completed the new RBD and established measures of generic resilience and health-related outcomes. Exploratory factor analysis for the RBD yielded a 23-item 5-factor solution, and confirmatory factor analysis indicated adequate fit indices. Internal consistency, stability, concurrent validation and known-groups' validity were also supported. The RBD obtained higher responsiveness (6-month follow-up) than the generic resilience scale (BD sample). The RBD is a robust measure to monitor resilience in BD. Copyright © 2017 Elsevier Inc.

2015-01-01

Current measures for major depressive disorder focus primarily on the assessment of depressive symptoms, while often omitting other common features. However, the presence of comorbid features in the anxiety spectrum influences outcome and may effect treatment. More comprehensive measures of depression are needed that include the assessment of symptoms in the anxiety–depression spectrum. This study examines the reliability and validity of the Symptoms of Depression Questionnaire (SDQ), which assesses irritability, anger attacks, and anxiety symptoms together with the commonly considered symptoms of depression. Analysis of the factor structure of the SDQ identified 5 subscales, including one in the anxiety–depression spectrum, with adequate internal consistency and concurrent validity. The SDQ may be a valuable new tool to better characterize depression and identify and administer more targeted interventions. PMID:25275853

2018-09-01

The purpose of the present study was to evaluate the concurrent validity and test-retest repeatability of torso-worn IMU-derived power and jump height in a counter-movement jump test. Twenty-seven healthy recreationally active males (age, 21.9 [SD 2.0] y, height, 1.76 [0.7] m, mass, 73.7 [10.3] kg) wore an IMU and completed three counter-movement jumps a week apart. A force platform and a 3D motion analysis system were used to concurrently measure the jumps and subsequently derive power and jump height (based on take-off velocity and flight time). The IMU significantly overestimated power (mean difference = 7.3 W/kg; P < 0.001) compared to force-platform-derived power but good correspondence between methods was observed (Intra-class correlation coefficient [ICC] = 0.69). IMU-derived power exhibited good reliability (ICC = 0.67). Velocity-derived jump heights exhibited poorer concurrent validity (ICC = 0.72 to 0.78) and repeatability (ICC = 0.68) than flight-time-derived jump heights, which exhibited excellent validity (ICC = 0.93 to 0.96) and reliability (ICC = 0.91). Since jump height and power are closely related, and flight-time-derived jump height exhibits excellent concurrent validity and reliability, flight-time-derived jump height could provide a more desirable measure compared to power when assessing athletic performance in a counter-movement jump with IMUs.

Assessment of the Tobacco Dependence Screener Among Smokeless Tobacco Users.

Variants of the Fagerström Tolerance Questionnaire and Fagerström Test for Nicotine Dependence (FTND) are widely used to study dependence among smokeless tobacco (ST) users. However, there is a need for a dependence measure which is based on the clinical definition of dependence and is easy to administer. The Tobacco Dependence Screener (TDS), a self-administered 10-item scale, is based on the Diagnostic and Statistical Manual, fourth edition (DSM-IV) and ICD-10 definitions of dependence. It is commonly used as a tobacco dependence screening tool in cigarette smoking studies but it has not been evaluated for dependence in ST users. The purpose of this study is to evaluate the TDS as a measure of tobacco dependence among ST users. Data collected from a community-based sample of exclusive ST users living in Oklahoma (n = 95) was used for this study. TDS was adapted to be used for ST dependence as the references for smoking were changed to ST use. Concurrent validity and reliability of TDS were evaluated. Salivary cotinine concentration was used as a criterion variable. Overall accuracy of the TDS was assessed by receiver's operating characteristic (ROC) curve and optimal cutoff scores for dependence diagnosis were evaluated. There was no floor or ceiling effect in TDS score (mean = 5.42, SD = 2.61). Concurrent validity of TDS as evaluated by comparing it with FTND-ST was affirmative. Study findings showed significant association between TDS and salivary cotinine concentration. The internal consistency assessed by Cronbach's alpha indicated that TDS had acceptable reliability (α = 0.765). TDS was negatively correlated with time to first chew/dip and positively correlated with frequency (number of chews per day) and years of ST use. Results of logistic regression analysis showed that at an optimal cutoff score of TDS 5+, ST users classified as dependent had significantly higher cotinine concentration and FTND-ST scores. TDS demonstrated acceptable reliability and concurrent validity among ST users. These findings are consistent with the results of previous cigarette smoking studies evaluating TDS. A self-administered tobacco dependence measure for ST users based on a clinical definition of dependence is an effective tool in research setting. ST dependence research is still evolving. This is the first study of the TDS among ST users providing preliminary evidence about some of the psychometric properties of the scale. Similar to cigarette smokers, TDS is an effective measure of ST dependence. Study showed moderate reliability and affirmative concurrent validity of the TDS among ST users. © The Author 2015.

Linguistically adapted oral health literacy tools are helpful to assess oral health literacy among local population with clarity and understandability. The original oral health literacy adult questionnaire, Oral Health Literacy Adult Questionnaire, was given in English (2013), consisting of 17 items under 4 domains. The present study rationalizes to culturally adapt and validate Oral Health Literacy Adult Questionnaire into Hindi language. Thus, we objectified to translate Oral Health Literacy Adult Questionnaire into Hindi and test its psychometric properties like reliability and validity among primary school teachers. The Oral Health Literacy Adult Questionnaire was translated into Oral Health Literacy Adult Questionnaire - Hindi Version using the World Health Organization recommended translation back-translation protocol. During pre-testing, an expert panel assessed content validity of the questionnaire. Face validity was assessed on a small sample of 10 individuals. A cross-sectional study was conducted (June-July 2015) and OHL-AQ-H was administered on a convenient sample of 170 primary school teachers. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and Intra-class correlation coefficient (ICC), respectively, with 2 weeks interval to ascertain adherence to the questionnaire response. Predictive validity was tested by comparing OHL-AQ-H scores with clinical indicators like oral hygiene scores and dental caries scores. The concurrent and discriminant validity was assessed through self-reported oral health and through negative association with sociodemographic variables. The data was analyzed by descriptive tests using chi-square and bivariate logistic regression in SPSS software, version 20 and p<0.05 was considered as the significance level. The mean OHL-AQ-H score was 13.58±2.82. ICC and Cronbach's alpha for Oral Health Literacy Adult Questionnaire - Hindi Version were 0.94 and 0.70, respectively. Comparisons of varying levels of oral health literacy with self-reported oral health established significant concurrent validity (p=0.01). Significant predictive validity was observed between OHL-AQ-H scores and clinical parameters like oral hygiene status (p=0.005) and dentition status (p=0.001). The translated and culturally adapted Oral Health Literacy Adult Questionnaire - Hindi Version indicated good reliability and validity among primary school teachers to assess oral health literacy among Hindi speaking population. Hence, improving OHL levels and implementing education oriented policies can improve the quality of life.

The present research describes the development and psychometric evaluation of a second version of the Acceptance and Action Questionnaire (AAQ-II), which assesses the construct referred to as, variously, acceptance, experiential avoidance, and psychological inflexibility. Results from 2,816 participants across six samples indicate the satisfactory structure, reliability, and validity of this measure. For example, the mean alpha coefficient is .84 (.78-.88), and the 3- and 12-month test-retest reliability is .81 and .79, respectively. Results indicate that AAQ-II scores concurrently, longitudinally, and incrementally predict a range of outcomes, from mental health to work absence rates, that are consistent with its underlying theory. The AAQ-II also demonstrates appropriate discriminant validity. The AAQ-II appears to measure the same concept as the AAQ-I (r=.97) but with better psychometric consistency. Copyright © 2011.

Public health practice has come to increasing recognition of health promotion and the central role of knowledge, attitude, beliefs and practices in achieving health promotion. Health literacy (HL) is an under-explored topic in South Eastern European countries. There are no HL reports from Albania to date. The aim of this study was to assess the concurrent validity of the European Health Literacy Survey Questionnaire (HLS-EU-Q) and the Test of Functional Health Literacy in Adults (TOFHLA) in a population-based sample of adults in Albania. A cross-sectional study was conducted in 2013 in Tirana, Albania, including 239 individuals aged ≥ 18 years (61% women; 87% response). A structured interviewer-administered questionnaire was applied twice (test and retest procedure after 2 weeks) including HLS-EU-Q and TOFHLA instruments. The internal consistency was high for both instruments (Cronbach's alpha for the test procedure was 0.92 for TOFHLA and 0.98 for HLS-EU-Q). Both tools exhibited a high stability over time (Spearman's rho: 0.88 for TOFHLA and 0.87 for HLS-EU). Mean values of both instruments were similar in men and women (mean score for TOFHLA: 76.0 vs. 76.5, P = 0.83; mean score for HLS-EU-Q: 32.2 vs. 32.6, P = 0.63). For both instruments, higher HL scores were significantly associated with younger age, higher educational and economic level and lower body mass index. Our study provides valuable novel evidence on concurrent validation of two major HL instruments in a South Eastern European population-based sample. Future studies should be conducted in order to confirm and expand our findings. © The Author 2014. Published by Oxford University Press on behalf of the European Public Health Association.

Validity and reliability of the cross-cultural adaptive translation of the Alberta Infant Motor Scale (AIMS), to monitor gross motor development in infants from 0 to 18 months of age, were evaluated. A cross-cultural translation was used to generate a Spanish version of the AIMS. Fifty infants at risk or with diagnosis of motor delay, 0-18 months of age, participated in this study. Two independent physical therapists scored infants on the AIMS. Concurrent validity was tested using the AIMS and the Bayley Scales of Infant and Toddler Development - III (Bayley - III). Reliability and the internal consistency were high (ICCs ranged from 0.94 to 1.00 and KR-20 ranged from 0.90 to 0.98, respectively). AIMS and Bayley - III scores correlated strongly (r = 0.97). The Spanish version of the AIMS presented excellent validity and reliability. Further studies are suggested in order to assess the AIMS in preterm babies.

The present study examined the psychometric properties and diagnostic efficiency of the Davidson Trauma Scale (DTS), a self-report measure of posttraumatic stress disorder (PTSD) symptoms. Participants included 158 U.S. military veterans who have served since September 11, 2001 (post-9/11). Results support the DTS as a valid self-report measure of PTSD symptoms. The DTS demonstrated good internal consistency, concurrent validity, and convergent and divergent validity. Diagnostic efficiency was excellent when discriminating between veterans with PTSD and veterans with no Axis I diagnosis. However, although satisfactory by conventional standards, efficiency was substantially attenuated when discriminating between PTSD and other Axis I diagnoses. Thus, results illustrate that potency of the DTS as a diagnostic aid was highly dependent on the comparison group used for analyses. Results are discussed in terms of applications to clinical practice and research.

2012-05-01

The validity of upper-limb neurodynamic tests (ULNTs) for detecting peripheral neuropathic pain (PNP) was assessed by reviewing the evidence on plausibility, the definition of a positive test, reliability, and concurrent validity. Evidence was identified by a structured search for peer-reviewed articles published in English before May 2011. The quality of concurrent validity studies was assessed with the Quality Assessment of Diagnostic Accuracy Studies tool, where appropriate. Biomechanical and experimental pain data support the plausibility of ULNTs. Evidence suggests that a positive ULNT should at least partially reproduce the patient's symptoms and that structural differentiation should change these symptoms. Data indicate that this definition of a positive ULNT is reliable when used clinically. Limited evidence suggests that the median nerve test, but not the radial nerve test, helps determine whether a patient has cervical radiculopathy. The median nerve test does not help diagnose carpal tunnel syndrome. These findings should be interpreted cautiously, because diagnostic accuracy might have been distorted by the investigators' definitions of a positive ULNT. Furthermore, patients with PNP who presented with increased nerve mechanosensitivity rather than conduction loss might have been incorrectly classified by electrophysiological reference standards as not having PNP. The only evidence for concurrent validity of the ulnar nerve test was a case study on cubital tunnel syndrome. We recommend that researchers develop more comprehensive reference standards for PNP to accurately assess the concurrent validity of ULNTs and continue investigating the predictive validity of ULNTs for prognosis or treatment response.

Reliability, validity and administrative burden of the community reintegration of injured service members computer adaptive test (CRIS-CAT)”

PubMed Central

2012-01-01

Background The Computer Adaptive Test version of the Community Reintegration of Injured Service Members measure (CRIS-CAT) consists of three scales measuring Extent of, Perceived Limitations in, and Satisfaction with community integration. The CRIS-CAT was developed using item response theory methods. The purposes of this study were to assess the reliability, concurrent, known group and predictive validity and respondent burden of the CRIS-CAT. The CRIS-CAT was developed using item response theory methods. The purposes of this study were to assess the reliability, concurrent, known group and predictive validity and respondent burden of the CRIS-CAT. Methods This was a three-part study that included a 1) a cross-sectional field study of 517 homeless, employed, and Operation Enduring Freedom / Operation Iraqi Freedom (OEF/OIF) Veterans; who completed all items in the CRIS item set, 2) a cohort study with one year follow-up study of 135 OEF/OIF Veterans, and 3) a 50-person study of CRIS-CAT administration. Conditional reliability of simulated CAT scores was calculated from the field study data, and concurrent validity and known group validity were examined using Pearson product correlations and ANOVAs. Data from the cohort were used to examine the ability of the CRIS-CAT to predict key one year outcomes. Data from the CRIS-CAT administration study were used to calculate ICC (2,1) minimum detectable change (MDC), and average number of items used during CAT administration. Results Reliability scores for all scales were above 0.75, but decreased at both ends of the score continuum. CRIS-CAT scores were correlated with concurrent validity indicators and differed significantly between the three Veteran groups (P < .001). The odds of having any Emergency Room visits were reduced for Veterans with better CRIS-CAT scores (Extent, Perceived Satisfaction respectively: OR = 0.94, 0.93, 0.95; P < .05). CRIS-CAT scores were predictive of SF-12 physical and mental health related quality of life scores at the 1 year follow-up. Scales had ICCs >0.9. MDCs were 5.9, 6.2, and 3.6, respectively for Extent, Perceived and Satisfaction subscales. Number of items (mn, SD) administered at Visit 1 were 14.6 (3.8) 10.9 (2.7) and 10.4 (1.7) respectively for Extent, Perceived and Satisfaction subscales. Conclusion The CRIS-CAT demonstrated sound measurement properties including reliability, construct, known group and predictive validity, and it was administered with minimal respondent burden. These findings support the use of this measure in assessing community reintegration. PMID:22984850

Prospective validation of the Scoliosis Research Society Outcomes Questionnaire French-Canadian version (SRS-22fv) in adolescent patients with spondylolisthesis. To determine the measurement properties of the SRS-22fv. The SRS-22 is widely used for the assessment of health-related quality of life in adolescent idiopathic scoliosis (AIS) and other spinal deformities. Spondylolisthesis has an important effect on quality of life. The instrument was previously used in this population, although its measurement properties remained unknown. We aim to determine its reliability, factorial, concurrent validity, and its discriminant capacity in an adolescent spondylolisthesis population. The SRS-22fv was tested in 479 subjects (272 patients with spondylolisthesis, 143 with AIS, and 64 controls) at a single institution. Its reliability was measured using the coefficient of internal consistency, concurrent validity by the short form-12 (SF-12v2 French version) and discriminant validity using multivariate analysis of variance, analysis of covariance, and multivariate linear regression. The SRS-22fv showed a good global internal consistency (spondylolisthesis: Cronbach α = 0.91, AIS: 0.86, and controls: 0.78) in all its domains for spondylolisthesis patients. It showed a factorial structure consistent with the original questionnaire, with 60% of explained variance under four factors. Moderate to high correlation coefficients were found for specifically corresponding domains between SRS-22fv and SF-12v2. Boys had higher scores than do girls, scores worsened with increasing age and body mass index. Analysis of covariance showed statistically significant differences between patients with spondylolisthesis, patients with AIS, and controls when controlling for age, sex, body mass index, pain, function, and self-image scores. In the spondylolisthesis group, scores on all domains and mean total scores were significantly lower in surgical candidates and in patients with high-grade spondylolisthesis. Low to moderate ceiling effects were shown in function (1.1%), self-image (10.7%), and pain (13.6%). The SRS-22fv can discriminate between healthy and spondylolisthesis subjects. It can be used in spondylolisthesis patients to assess health-related quality of life. 4.

Concurrent validity and test-retest reliability of the Microsoft Kinect in quantification of manual wheelchair propulsion were examined. Data were collected from five manual wheelchair users on a roller system. Three Kinect sensors were used to assess test-retest reliability with a still pose. Three systems were used to assess concurrent validity of the Kinect to measure propulsion kinematics (joint angles, push loop characteristics): Kinect, Motion Analysis, and Dartfish ProSuite (Dartfish joint angles were limited to shoulder and elbow flexion). Intraclass correlation coefficients revealed good reliability (0.87-0.99) between five of the six joint angles (neck flexion, shoulder flexion, shoulder abduction, elbow flexion, wrist flexion). ICCs suggested good concurrent validity for elbow flexion between the Kinect and Dartfish and between the Kinect and Motion Analysis. Good concurrent validity was revealed for maximum height, hand-axle relationship, and maximum area (0.92-0.95) between the Kinect and Dartfish and maximum height and hand-axle relationship (0.89-0.96) between the Kinect and Motion Analysis. Analysis of variance revealed significant differences (p < 0.05) in maximum length between Dartfish (mean 58.76 cm) and the Kinect (40.16 cm). Results pose promising research and clinical implications for propulsion assessment and overuse injury prevention with the application of current findings to future technology.

2012-10-01

To perform a cross-cultural adaptation of the Portuguese version of the Maslach Burnout Inventory for students (MBI-SS), and investigate its reliability, validity and cross-cultural invariance. The face validity involved the participation of a multidisciplinary team. Content validity was performed. The Portuguese version was completed in 2009, on the internet, by 958 Brazilian and 556 Portuguese university students from the urban area. Confirmatory factor analysis was carried out using as fit indices: the χ²/df, the Comparative Fit Index (CFI), the Goodness of Fit Index (GFI) and the Root Mean Square Error of Approximation (RMSEA). To verify the stability of the factor solution according to the original English version, cross-validation was performed in 2/3 of the total sample and replicated in the remaining 1/3. Convergent validity was estimated by the average variance extracted and composite reliability. The discriminant validity was assessed, and the internal consistency was estimated by the Cronbach's alpha coefficient. Concurrent validity was estimated by the correlational analysis of the mean scores of the Portuguese version and the Copenhagen Burnout Inventory, and the divergent validity was compared to the Beck Depression Inventory. The invariance of the model between the Brazilian and the Portuguese samples was assessed. The three-factor model of Exhaustion, Disengagement and Efficacy showed good fit (c 2/df = 8.498, CFI = 0.916, GFI = 0.902, RMSEA = 0.086). The factor structure was stable (λ:χ²dif = 11.383, p = 0.50; Cov: χ²dif = 6.479, p = 0.372; Residues: χ²dif = 21.514, p = 0.121). Adequate convergent validity (VEM = 0.45;0.64, CC = 0.82;0.88), discriminant (ρ² = 0.06;0.33) and internal consistency (α = 0.83;0.88) were observed. The concurrent validity of the Portuguese version with the Copenhagen Inventory was adequate (r = 0.21, 0.74). The assessment of the divergent validity was impaired by the approach of the theoretical concept of the dimensions Exhaustion and Disengagement of the Portuguese version with the Beck Depression Inventory. Invariance of the instrument between the Brazilian and Portuguese samples was not observed (λ:χ²dif = 84.768, p<0.001; Cov: χ²dif = 129.206, p < 0.001; Residues: χ²dif = 518.760, p < 0.001). The Portuguese version of the Maslach Burnout Inventory for students showed adequate reliability and validity, but its factor structure was not invariant between the countries, indicating the absence of cross-cultural stability.

Validating Quantitative Measurement Using Qualitative Data: Combining Rasch Scaling and Latent Semantic Analysis in Psychiatry

NASA Astrophysics Data System (ADS)

Lange, Rense

2015-02-01

An extension of concurrent validity is proposed that uses qualitative data for the purpose of validating quantitative measures. The approach relies on Latent Semantic Analysis (LSA) which places verbal (written) statements in a high dimensional semantic space. Using data from a medical / psychiatric domain as a case study - Near Death Experiences, or NDE - we established concurrent validity by connecting NDErs qualitative (written) experiential accounts with their locations on a Rasch scalable measure of NDE intensity. Concurrent validity received strong empirical support since the variance in the Rasch measures could be predicted reliably from the coordinates of their accounts in the LSA derived semantic space (R2 = 0.33). These coordinates also predicted NDErs age with considerable precision (R2 = 0.25). Both estimates are probably artificially low due to the small available data samples (n = 588). It appears that Rasch scalability of NDE intensity is a prerequisite for these findings, as each intensity level is associated (at least probabilistically) with a well- defined pattern of item endorsements.

This work assessed the concurrent and face validity of the MacArthur scale, which attempts to capture subjective social status in society, neighborhood and work contexts. The study population comprised a convenience sample made up of 159 adult participants of the ELSA-Brasil cohort study conducted in Minas Gerais between 2012 and 2014. The analysis was conducted drawing on Conceptual Metaphor Theory and using corpus linguistic methods. Concurrent validity was shown to be moderate for the society ladder (Kappaw = 0.55) and good for the neighborhood (Kappaw = 0.60) and work (Kappaw = 0,67) ladders. Face validity indicated that the MacArthur scale really captures subjective social status across indicators of socioeconomic position, thus confirming that it is a valuable tool for the study of social inequalities in health Brazil.

PubMed Central

2017-01-01

Objective To establish the reliability and validity the Korean version of the Stroke Impact Scale (K-SIS) 3.0. Methods A total of 70 post-stroke patients were enrolled. All subjects were evaluated for general characteristics, Mini-Mental State Examination (MMSE), the National Institutes of Health Stroke Scale (NIHSS), Modified Barthel Index, Hospital Anxiety and Depression Scale (HADS). The SF-36 and K-SIS 3.0 assessed their health-related quality of life. Statistical analysis after evaluation, determined the reliability and validity of the K-SIS 3.0. Results A total of 70 patients (mean age, 54.97 years) participated in this study. Internal consistency of the SIS 3.0 (Cronbach's alpha) was obtained, and all domains had good co-efficiency, with threshold above 0.70. Test-retest reliability of SIS 3.0 required correlation (Spearman's rho) of the same domain scores obtained on the first and second assessments. Results were above 0.5, with the exception of social participation and mobility. Concurrent validity of K-SIS 3.0 was assessed using the SF-36, and other scales with the same or similar domains. Each domain of K-SIS 3.0 had a positive correlation with corresponding similar domain of SF-36 and other scales (HADS, MMSE, and NIHSS). Conclusion The newly developed K-SIS 3.0 showed high inter-intra reliability and test-retest reliabilities, together with high concurrent validity with the original and various other scales, for patients with stroke. K-SIS 3.0 can therefore be used for stroke patients, to assess their health-related quality of life and treatment efficacy. PMID:28758075

The Relapse Assessment for Schizophrenia Patients (RASP) was developed as a six-question self-report screener that measures indicators of Increased Anxiety and Social Isolation to assess patient stability and predict imminent relapse. This paper describes the development and psychometric characteristics of the RASP. The RASP and Positive and Negative Syndrome Scale (PANSS) were administered to patients with schizophrenia (n=166) three separate times. Chart data were collected on a subsample of patients (n=81). Psychometric analyses of RASP included tests of reliability, construct validity, and concurrent validity of items. Factors from RASP were correlated with subscales from PANSS (sensitivity to change and criterion validity [agreement between RASP and evidence of relapse]). Test-retest reliability returned modest to strong agreement at the item level and strong agreement at the questionnaire level. RASP showed good item response curves and internal consistency for the total instrument and within each of the two subscales (Increased Anxiety and Social Isolation). RASP Total Score and subscales showed good concurrent validity when correlated with PANSS Total Score, Positive, Excitement, and Anxiety subscales. RASP correctly predicted relapse in 67% of cases, with good specificity and negative predictive power and acceptable positive predictive power and sensitivity. The reliability and validity data presented support the use of RASP in settings where addition of a brief self-report assessment of relapse risk among patients with schizophrenia may be of benefit. Ease of use and scoring, and the ability to administer without clinical supervision allows for routine administration and assessment of relapse risk.

The Motor tic, Obsessions and compulsions, Vocal tic Evaluation Survey (MOVES) is a self-report scale suggested as a severity scale for tics and related sensory phenomena observed in Gilles de la Tourette syndrome (GTS) and recommended as a screening instrument by the Committee on Rating Scale Development of the International Parkinson's Disease and Movement Disorder Society. To cross-culturally adapt a French version of the MOVES and to evaluate its psychometric properties. After the cross-cultural adaptation of the MOVES, we assessed its psychometric properties in 53 patients aged 12-16 years and in 54 patients aged 16 years and above: reliability and construct validity (relationships between items and scales), internal consistency and concurrent validity with the Yale Global Tic Severity Scale (YGTSS) and the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) or the auto-Yale-Brown scale. The results showed very good acceptability with response rates greater than 92%, good internal consistency (Cronbach's alpha ranging from 0.62 and 0.89) and good test-retest reliability (ICCs ranging from 0.59 to 0.91). Concurrent validity with the YGTSS, CY-BOCS and auto-Yale-Brown scales showed strong expected correlations. The cut-off points tested for diagnostic performance gave satisfactory values of sensitivity, specificity, and positive and negative predictive values. Our study provides evidence of the good psychometric properties of the French version of the MOVES. The cross-cultural adaptation of this specific instrument will allow investigators to include French-speaking persons with GTS aged 12 years and over in national and international collaboration research projects.

The purpose of this study was to examine the test-retest reliability, internal consistency and concurrent validity of the Athletic Skills Track (AST). During a regular PE lesson, 930 4- to 12-year old children (448 girls, 482 boys) completed two motor skill competence tests: (1) the Körperkoordination-Test für Kinder (KTK) and (2) an age-related version of the AST (age 4-6 years: AST-1, age 6-9 years: AST-2, and age 9-12 years: AST-3). The test-retest reliability of the AST was high (AST-1: ICC = 0.881 (95% CI: 0.780-0.934); AST-2: ICC = 0.802 (95% CI: 0.717-0.858); and AST-3: ICC = 0.800 (95% CI: 0.669-0.871). The internal consistency, concerning the three age-bands of the AST was above the acceptable level of Cronbach's α > 0.70 (AST-1: α = 0.764; AST-2: α = 0.700; and AST-3: α = 0.763). There was a moderate to high correlation between the time to complete the AST, and the age- and gender-related motor quotients of the KTK (AST-1: r = -0.747, p = 0.01; AST-2: r = -0.646, p = 0.01; and AST-3: r = -0.602, p = 0.01). The Athletic Skills Track is a reliable and valid assessment tool to assess motor skill competence among 4- to 12-year old children in the PE setting.

Heavy drinking and associated consequences are widespread among U.S. college students. Recently, Read et al. (Read, J. P., Kahler, C. W., Strong, D., & Colder, C. R. (2006). Development and preliminary validation of the Young Adult Alcohol Consequences Questionnaire. Journal of Studies on Alcohol, 67, 169-178) developed the Young Adult Alcohol Consequences Questionnaire (YAACQ) to assess the broad range of consequences that may result from heavy drinking in the college milieu. In the present study, we sought to add to the psychometric validation of this measure by employing a prospective design to examine the test-retest reliability, concurrent validity, and predictive validity of the YAACQ. We also sought to examine the utility of the YAACQ administered early in the semester in the prediction of functional outcomes later in the semester, including the persistence of heavy drinking, and academic functioning. Ninety-two college students (48 females) completed a self-report assessment battery during the first weeks of the Fall semester, and approximately one week later. Additionally, 64 subjects (37 females) participated at an optional third time point at the end of the semester. Overall, the YAACQ demonstrated strong internal consistency, test-retest reliability, and concurrent and predictive validity. YAACQ scores also were predictive of both drinking frequency, and "binge" drinking frequency. YAACQ total scores at baseline were an early indicator of academic performance later in the semester, with greater number of total consequences experienced being negatively associated with end-of-semester grade point average. Specific YAACQ subscale scores (Impaired Control, Dependence Symptoms, Blackout Drinking) showed unique prediction of persistent drinking and academic outcomes.

Suboptimal care for people with dementia in hospital settings has been reported and is attributed to the lack of knowledge and inadequate attitudes in dementia care among health professionals. Educational interventions have been widely used to improve care outcomes; however, Chinese-language instruments used in dementia educational interventions for health professionals are lacking. The aims of this study were to select, translate and evaluate instruments used in dementia educational interventions for Chinese health professionals in acute-care hospitals. A cross-sectional study design was used. A modified stratified random sampling was used to recruit 442 participants from different levels of hospitals in Changsha, China. Dementia care competence was used as a framework for the selection and evaluation of Alzheimer's Disease Knowledge Scale and Dementia Care Attitudes Scale for health professionals in the study. These two scales were translated into Chinese using forward and back translation method. Content validity, test-retest reliability and internal consistency were assessed. Construct validity was tested using exploratory factor analysis. Known-group validity was established by comparing scores of Alzheimer's Disease Knowledge Scale and Dementia Care Attitudes Scale in two sub-groups. A person-centred care scale was utilised as a gold standard to establish concurrent validity of these two scales. Results demonstrated acceptable content validity, internal consistency, test-retest reliability and concurrent validity. Exploratory factor analysis presented a single-factor structure of the Chinese Alzheimer's Disease Knowledge Scale and a two-factor structure of the Chinese Dementia Care Attitudes Scale, supporting the conceptual dimensions of the original scales. The Chinese Alzheimer's Disease Knowledge Scale and Chinese Dementia Care Attitudes Scale demonstrated known-group validity evidenced by significantly higher scores identified from the sub-group with a longer work experience compared to those in the sub-group with less work experience. The use of dementia care competence as a framework to inform the selection and evaluation of instruments used in dementia educational interventions for health professionals has wide applicability in other areas. The results support that Chinese Alzheimer's Disease Knowledge Scale and Chinese Dementia Care Attitudes Scale are reliable and valid instruments for health professionals to use in acute-care settings.

Achilles tendinopathy is the predominant overuse injury in runners. To further investigate this overload injury in transverse and longitudinal studies a valid, responsive and reliable outcome measure is demanded. Most questionnaires have been developed for English-speaking populations. This is also true for the VISA-A score, so far representing the only valid, reliable, and disease specific questionnaire for Achilles tendinopathy. To internationally compare research results, to perform multinational studies or to exclude bias originating from subpopulations speaking different languages within one country an equivalent instrument is demanded in different languages. The aim of this study was therefore to cross-cultural adapt and validate the VISA-A questionnaire for German-speaking Achilles tendinopathy patients. According to the "guidelines for the process of cross-cultural adaptation of self-report measures" the VISA-A score was cross-culturally adapted into German (VISA-A-G) using six steps: Translation, synthesis, back translation, expert committee review, pretesting (n = 77), and appraisal of the adaptation process by an advisory committee determining the adequacy of the cross-cultural adaptation. The resulting VISA-A-G was then subjected to an analysis of reliability, validity, and internal consistency in 30 Achilles tendinopathy patients and 79 asymptomatic people. Concurrent validity was tested against a generic tendon grading system (Percy and Conochie) and against a classification system for the effect of pain on athletic performance (Curwin and Stanish). The "advisory committee" determined the VISA-A-G questionnaire as been translated "acceptable". The VISA-A-G questionnaire showed moderate to excellent test-retest reliability (ICC = 0.60 to 0.97). Concurrent validity showed good coherence when correlated with the grading system of Curwin and Stanish (rho = -0.95) and for the Percy and Conochie grade of severity (rho 0.95). Internal consistency (Cronbach's alpha) for the total VISA-A-G scores of the patients was calculated to be 0.737. The VISA-A questionnaire was successfully cross-cultural adapted and validated for use in German speaking populations. The psychometric properties of the VISA-A-G questionnaire are similar to those of the original English version. It therefore can be recommended as a sufficiently robust tool for future measuring clinical severity of Achilles tendinopathy in German speaking patients.

Heterogeneity of psychosis presents significant challenges for classification. Between two and 12 symptom dimensions have been proposed, and consensus is lacking. The present study sought to identify uniquely informative models by comparing the validity of these alternatives. An epidemiologic cohort of 628 first-admission inpatients with psychosis was interviewed 6 times over two decades and completed an electrophysiological assessment of error processing at year 20. We first analyzed a comprehensive set of 49 symptoms rated by interviewers at baseline, progressively extracting from one to 12 factors. Next, we compared the ability of resulting factor solutions to (a) account for concurrent neural dysfunction and (b) predict 20-year role, social, residential, and global functioning, and life satisfaction. A four-factor model showed incremental validity with all outcomes, and more complex models did not improve explanatory power. The four dimensions—reality distortion, disorganization, inexpressivity, and apathy/asociality—were replicable in 5 follow-ups, internally consistent, stable across assessments, and showed strong discriminant validity. These results reaffirm the value of separating disorganization and reality distortion, are consistent with recent findings distinguishing inexpressivity and apathy/asociality, and suggest that these four dimensions are fundamental to understanding neural abnormalities and long-term outcomes in psychosis.

To develop and validate a disease-specific health-related quality of life (HRQOL) instrument for adults with systemic lupus erythematosus (SLE). The work consisted of 6 stages. Stage 1 included item generation for questionnaire content from semistructured interviews with SLE patients. In stage 2 item selection for the draft questionnaire was performed by thematic analysis of the patient interview transcripts and expert panel agreement. In stage 3 the content validity of the draft questionnaire was assessed by patients completing the questionnaire and providing critical feedback. In stages 4 and 5 construct validity and internal reliability of the 3 versions of the LupusQoL were evaluated using principal component analysis with varimax rotation and Cronbach's alpha coefficients, respectively. In stage 6 discriminatory validity, concurrent validity, and test-retest reliability were evaluated. Stages 1, 2, and 3 resulted in a preliminary instrument containing 63 items. In stage 4, 8 domains were identified. This factor structure, accounting for 82% of the variance, was confirmed in stage 5. The domains and Cronbach's alpha coefficients were physical health (0.94), emotional health (0.94), body image (0.89), pain (0.92), planning (0.93), fatigue (0.88), intimate relationships (0.96), and burden to others (0.94). Discriminant validity was demonstrated for different levels of disease activity (British Isles Lupus Assessment Group Index) and damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index). High correlations (r = 0.71-0.79) between comparable domains of the Short Form 36 and the LupusQoL assured acceptable concurrent validity. Good test-retest reliability (r = 0.72-0.93) was demonstrated. The LupusQoL is a validated SLE-specific HRQOL instrument with 34 items across 8 domains defined by patients as being important.

This paper outlines the development and validation of the Work-Family Conflict Scale (WAFCS) designed to measure work-to-family conflict (WFC) and family-to-work conflict (FWC) for use with parents of young children. An expert informant and consumer feedback approach was utilised to develop and refine 20 items, which were subjected to a rigorous validation process using two separate samples of parents of 2-12 year old children (n = 305 and n = 264). As a result of statistical analyses several items were dropped resulting in a brief 10-item scale comprising two subscales assessing theoretically distinct but related constructs: FWC (five items) and WFC (five items). Analyses revealed both subscales have good internal consistency, construct validity as well as concurrent and predictive validity. The results indicate the WAFCS is a promising brief measure for the assessment of work-family conflict in parents. Benefits of the measure as well as potential uses are discussed.

The use of the Internet has been increasing dramatically over the decade in Malaysia. Excessive usage of the Internet has lead to a phenomenon called Internet addiction. There is a need for a reliable, valid, and simple-to-use scale to measure Internet addiction in the Malaysian population for clinical practice and research purposes. The aim of this study was to validate the Malay version of the Internet Addiction Test, using a sample of 162 medical students. The instrument displayed good internal consistency (Cronbach's α = .91), parallel reliability (intraclass coefficient = .88, P < .001), and concurrent validity with the Compulsive Internet Use Scale (Pearson's correlation = .84, P < .001). Receiver operating characteristic analysis showed that 43 was the optimal cutoff score to discriminate students with and without Internet dependence. Principal component analysis with varimax rotation identified a 5-factor model. The Malay version of the Internet Addiction Test appeared to be a valid instrument for assessing Internet addiction in Malaysian university students. © 2012 APJPH.

Attitudes Toward Transgender Men and Women: Development and Validation of a New Measure

Billard, Thomas J

2018-01-01

A series of three studies were conducted to generate, develop, and validate the Attitudes toward Transgender Men and Women (ATTMW) scale. In Study 1, 120 American adults responded to an open-ended questionnaire probing various dimensions of their perceptions of transgender individuals and identity. Qualitative thematic analysis generated 200 items based on their responses. In Study 2, 238 American adults completed a questionnaire consisting of the generated items. Exploratory factor analysis (EFA) revealed two non-identical 12-item subscales (ATTM and ATTW) of the full 24-item scale. In Study 3, 150 undergraduate students completed a survey containing the ATTMW and a number of validity-testing variables. Confirmatory factor analysis (CFA) verified the single-factor structures of the ATTM and ATTW subscales, and the convergent, discriminant, predictive, and concurrent validities of the ATTMW were also established. Together, our results demonstrate that the ATTMW is a reliable and valid measure of attitudes toward transgender individuals. PMID:29666595

2017-01-01

We describe 2 studies designed to evaluate scores on the Multidimensional Shame-related Response Inventory-21 (MSRI-21), a recently developed instrument that measures affective and behavioral responses to shame. The inventory assesses shame-related responses in 3 categories: negative self-evaluation, fear of social consequences, and maladaptive behavior tendency. For Study 1, (N = 743) undergraduates completed the MSRI-21. Confirmatory factor analysis supported the validity of the MSRI-21 3-factor structure. Latent variable modeling of coefficient-α provided strong evidence for the internal consistency of scores on each scale. In Study 2, (N = 540) undergraduates completed the instrument along with 5 concurrent measures chosen for clinical significance. Achievement of factorial invariance supported the use of MSRI-21 scale scores to make valid mean comparisons across gender. In addition, MSRI-21 scale scores were associated as expected with scores on measures of self-harm, suicide, and other risk factors. Taken together, results of 2 studies support the internal consistency reliability, factorial validity, factorial invariance, and convergent validity of scores on the MSRI-21. Further work is needed to assess the temporal stability of the MSRI-21 scale scores, invariance across clinical status and other groupings, item-level measurement properties, and viability in highly symptomatic samples.

Validation measurements of satellite ocean color sensors require in situ measurements that are accurate, repeatable and traceable enough to distinguish variability between in situ measurements and variability in the signal being observed on orbit. The utility of using a Satlantic Profiler II equipped with HyperOCR radiometers (Hyperpro) for validating ocean color sensors is tested by assessing the stability of the calibration coefficients and by comparing Hyperpro in situ measurements to other instruments and between different Hyperpros in a variety of water types. Calibration and characterization of the NOAA Satlantic Hyperpro instrument is described and concurrent measurements of water-leaving radiances conducted during cruises are presented between this profiling instrument and other profiling, above-water and moored instruments. The moored optical instruments are the US operated Marine Optical BuoY (MOBY) and the French operated Boussole Buoy. In addition, Satlantic processing versions are described in terms of accuracy and consistency. A new multi-cast approach is compared to the most commonly used single cast method. Analysis comparisons are conducted in turbid and blue water conditions. Examples of validation matchups with VIIRS ocean color data are presented. With careful data collection and analysis, the Satlantic Hyperpro profiling radiometer has proven to be a reliable and consistent tool for satellite ocean color validation.

To describe the reliability and validity of a new measure, the Social Skills Questionnaire for Traumatic Brain Injury (SSQ-TBI). Fifty-one adults with severe TBI completed the SSQ-TBI questionnaire. Scores were compared to informant- and self-report on questionnaires addressing frontal lobe mediated behaviour, as well as performance on an objective measure of social cognition and neuropsychological tasks, in order to provide evidence of concurrent, divergent and predictive validity. Internal consistency was excellent at α = 0.90. Convergent validity was good, with informant ratings on the SSQ-TBI significantly correlated with Neuropsychiatric Inventory Disinhibition sub-scales (r = 0.50-63), the Current Behaviour Scale (r = 0.39-0.48) and Frontal Systems Behaviour Scale (r = 0.60-0.83). However, no relationship was seen with an objective measure of social skills or neuropsychological tasks of disinhibition. There was a significant relationship with real-world psychosocial outcomes on the Sydney Psychosocial Reintegration Scale-2 (r = -0.38--0.69) Conclusions: This study provides preliminary findings of good internal consistency and convergent and predictive validity of a social skills questionnaire adapted to be appropriate for individuals with TBI. Further assessment of psychometric properties such as test-re-test reliability and factor structure is warranted.

There remains a need for a quickly administered, stroke-specific, bedside measure of active wrist and finger movement for the expanding stroke population. The wrist stability and hand mobility scales of the upper extremity Fugl-Meyer Assessment (w/h UE FM) constitute a valid, reliable measure of paretic UE impairment in patients with active wrist and finger movement. The aim of this study was to determine performance on the w/h UE FM in a stable cohort of survivors of stroke with only palpable movement in their paretic wrist flexors. A single-center cohort study was conducted. Thirty-two individuals exhibiting stable, moderate upper extremity hemiparesis (15 male, 17 female; mean age=56.6 years, SD=10.1; mean time since stroke=4.6 years, SD=5.8) participated in the study, which was conducted at an outpatient rehabilitation clinic in the midwestern United States. The w/h UE FM and Action Research Arm Test (ARAT) were administered twice. Intraclass correlation coefficients (ICCs), Cronbach alpha, and ordinal alpha were computed to determine reliability, and Spearman rank correlation coefficients and Bland-Altman plots were computed to establish validity. Intraclass correlation coefficients for the w/h UE FM and ARAT were .95 and .99, respectively. The w/h UE FM intrarater reliability and internal consistency were greater than .80, and concurrent validity was greater than .70. This also was the first stroke rehabilitative study to apply ordinal alpha to examine internal consistency values, revealing w/h UE FM levels greater than .85. Concurrent validity findings were corroborated by Bland-Altman plots. It appears that the w/h UE FM is a promising tool to measure distal upper extremity movement in patients with little active paretic wrist and finger movement. This finding widens the segment of patients on whom the w/h UE FM can be effectively used and addresses a gap, as commonly used measures necessitate active distal upper extremity movement. © 2015 American Physical Therapy Association.

"Quality of life" has become a main focus of interest in medicine. The Pictorial Thai Quality of Life (PTQL) was developed in order to measure the Thai mental illness both in a clinical setting and community. The purpose of this study was to develop the Pictorial Thai Quality of Life (PTQL), having adequate and sufficient construct validity, discriminant power, concurrent validity, and reliability. To develop the Pictorial Thai Quality of Life Test, two samples groups were used in the present study: (1) pilot study samples: 30 samples and (2) survey samples were 672 samples consisting of normal, and psychiatric patients. The developing tests items were collected from a review of the literature in which all the items were based on the WHO definition of Quality of Life. Then, experts judgment by the Delphi technique was used in the first stage. After that a pilot study was used to evaluate the testing administration, and wording of the tests items. The final stage was collected data from the survey samples. The results of the present study showed that the final test was composed 25 items. The construct validity of this test consists of six domains: Physical, Cognitive, Affective, Social Function, Economic and Self-Esteem. All the PTQL items have sufficient discriminant power It was found to be statistically significant different at the. 001 level between those people with mental disorders and normal people. There was a high level of concurrent validity association with WHOQOL-BREF, Pearson correlation coefficient and Area under ROC curve were 0.92 and 0.97 respectively. The reliability coefficients for the Alpha coefficients of the PTQL total test was 0.88. The values of the six scales were from 0.81 to 0:91. The present study was directed at developing an effective psychometric properties pictorial quality of life questionnaire. The result will be a more direct and meaningful application of an instrument to detect the mental health illness poor quality of life in Thai communities.

The Suicide Assessment Scale (SUAS) was constructed to be sensitive to change of suicidality. It was recently found to be predictive of suicide in a group of suicide attempters. The aim of the present study was to evaluate the reliability and validity of a modified interview version of SUAS with defined scores and also a new self-rating version (SUAS-S). The subjects consisted of former inpatients, 42 persons who had been admitted because of a suicide attempt about 12 years ago and 22 control patients. The subjects were rated according to the SUAS, the SUAS-S, as well as the Montgomery Asberg Depression Rating Scale (MADRS). The interrater reliability was found to be high. The SUAS correlated significantly with the MADRS, but the concordance was not consistent, which indicates that the SUAS measures something different from depression. The SUAS-S correlated significantly with the interview-rated SUAS, thus exhibiting good concurrent validity. In summary, both the modified interview version of SUAS and the SUAS-S seem to be valid, reliable and easily used suicide assessment instruments.

Interest in assessing denial is still present, despite the criticisms concerning its definition and measurement. We tried to develop a questionnaire (Illness Denial Questionnaire, IDQ) assessing patients' and caregivers' denial in relation to their illness/disturbance. After a preliminary study, a final version of 24 dichotomous items (true/false) was selected. We hypothesized a theoretical model with three dimensions: denial of negative emotions, resistance to change, and conscious avoidance, the first two composing the actual Denial and the last representing an independent component of the illness denial behavior. The IDQ was administered to 400 subjects (219 patients and 181 caregivers) together with the Anxiety-Depression Questionnaire - Reduced form (AD-R), in order to assess concurrent validity. Confirmatory factor analysis (CFA), internal consistency indices (Cronbach's α and McDonald's ω), and test-retest analysis were performed. CFA and internal consistency indices (Cronbach's α: 0.87-0.96) indicated a clear and meaningful three-factor structure of IDQ, for both patients and caregivers. Further analyses showed good concurrent validity, with Denial and its subscale negatively associated with anxiety and depression and avoidance positively associated with anxiety and depression. The IDQ also showed a good stability ( r from 0.71 to 0.87). The IDQ demonstrated good psychometric properties. Denial of negative emotions and resistance to change seem to contribute to a real expression of denial, and conscious avoidance seems to constitute a further step in the process of cognitive-affective elaboration of the illness.

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.

Objective: This investigation examined the concurrent validity of a new video simulation assessing adolescent alcohol and marijuana decision making in peer contexts (A-SIDE). Method: One hundred eleven youth (60% female; age 14–19 years; 80% White, 12.6% Latino; 24% recruited from treatment centers) completed the A-SIDE simulation, self-report measures of alcohol and marijuana use and disorder symptoms, and measures of alcohol (i.e., drinking motives and expectancies) and marijuana (i.e., expectancies) cognitions in the laboratory. Results: Study findings support concurrent associations between behavioral willingness to use alcohol and marijuana on the simulation and current use variables as well as on drinking motives and marijuana expectancies. Relations with use variables were found even when sample characteristics were controlled. Interestingly, willingness to accept nonalcoholic beverages (e.g., soda) and food offers in the simulation were inversely related to recent alcohol and marijuana use behavior. Conclusions: These findings are consistent with prior work using laboratory simulations with college students and provide preliminary validity evidence for this procedure. Future work is needed to examine the predictive utility of the A-SIDE with larger and more diverse samples of youth. PMID:25343652

The study examines internal item/scale structure and concurrent validity of a newly developed 48-item questionnaire [General Coping Questionnaire (GCQ)] that measures 10 aspects of coping with chronic illness (self-trust, problem-reducing actions, change of values, social trust, minimization, fatalism, resignation, protest, isolation and intrusion). The tests were performed in two independent samples of persons with diabetes mellitus. The first sample consisted of 119 subjects with type I diabetes and the second sample of 184 subjects with type II diabetes. Concurrent validity was examined by comparisons with measures of health-related quality of life (SF-36), a measure of metabolic control (HbA1c) and incidence of diabetic complications. The item/scale structure was found to be similar and very good in both samples. The 10 dimensions correlated as expected with the measure of mental health, although the 'negative' dimensions of the GCQ correlated higher compared with the 'positive' dimensions. Weaker relations with metabolic control were also found in one of the samples. These tests provide further evidence that GCQ is a well-structured, relevant and reliable instrument for assessing coping reactions in chronic somatic conditions.

Psychosis has been repeatedly suggested to be affected by increases in stress and arousal. However, there is a dearth of evidence supporting the temporal link between stress, arousal, and psychosis during "real-world" functioning. This paucity of evidence may stem from limitations of current research methodologies. Our aim is to the test the feasibility and validity of a novel methodology designed to measure concurrent stress and arousal in individuals with psychosis during "real-world" daily functioning. Twenty patients with psychosis completed a 36-hour ambulatory assessment of stress and arousal. We used experience sampling method with palm computers to assess stress (10 times per day, 10 AM → 10 PM) along with concurrent ambulatory measurement of cardiac autonomic regulation using a Holter monitor. The clocks of the palm computer and Holter monitor were synchronized, allowing the temporal linking of the stress and arousal data. We used power spectral analysis to determine the parasympathetic contributions to autonomic regulation and sympathovagal balance during 5 minutes before and after each experience sample. Patients completed 79% of the experience samples (75% with a valid concurrent arousal data). Momentary increases in stress had inverse correlation with concurrent parasympathetic activity (ρ = -.27, P < .0001) and positive correlation with sympathovagal balance (ρ = .19, P = .0008). Stress and heart rate were not significantly related (ρ = -.05, P = .3875). The findings support the feasibility and validity of our methodology in individuals with psychosis. The methodology offers a novel way to study in high time resolution the concurrent, "real-world" interactions between stress, arousal, and psychosis. The authors discuss the methodology's potential applications and future research directions.

Health status is impaired in patients with interstitial lung disease (ILD). There is a paucity of tools that assess health status in ILD. The objective of this study was to develop and validate the King's Brief Interstitial Lung Disease questionnaire (K-BILD), a new health status measure for patients with ILD. Patients with ILD were recruited from outpatient clinics. The development of the questionnaire consisted of three phases: item generation; item reduction, allocation to domains by factor analysis, Rasch analysis to create unidimensional scales and validation; and repeatability testing. 173 patients with ILD (49 with idiopathic pulmonary fibrosis) completed a preliminary 71-item questionnaire. 56 items were removed due to redundancy, low factor loadings or poor fit to the Rasch model. The final version of the K-BILD questionnaire consisted of 15 items and three domains (breathlessness and activities, chest symptoms and psychological). Internal consistency assessed with Cronbach's α coefficient was 0.94 for the K-BILD total score. Concurrent validity of the K-BILD questionnaire was high compared with St George's Respiratory Questionnaire (r=0.90) and moderate with lung function (vital capacity, r=0.50). The K-BILD questionnaire was repeatable over 2 weeks (n=44), with intraclass correlation coefficients for domains and total score 0.86-0.94. The K-BILD construct validity for patients with idiopathic pulmonary fibrosis was similar to that of other ILDs. The K-BILD questionnaire is a brief, valid, self-completed health status measure for ILD. It could be used in the clinic to assess ILD from the patients' perspective.

This study investigated the reliability and validity of the Barry-Albright Dystonia Scale (BADS), the Burke-Fahn-Marsden Movement Scale (BFMMS), and the Unified Dystonia Rating Scale (UDRS) in patients with bilateral dystonic cerebral palsy (CP). Three raters independently scored videotapes of 10 patients (five males, five females; mean age 13 y 3 mo, SD 5 y 2 mo, range 5-22 y). One patient each was classified at levels I-IV in the Gross Motor Function Classification System and six patients were classified at level V. Reliability was measured by (1) intraclass correlation coefficient (ICC) for interrater reliability, (2) standard error of measurement (SEM) and smallest detectable difference (SDD), and (3) Cronbach's alpha for internal consistency. Validity was assessed by Pearson's correlations among the three scales used and by content analysis. Moderate to good interrater reliability was found for total scores of the three scales (ICC: BADS=0.87; BFMMS=0.86; UDRS=0.79). However, many subitems showed low reliability, in particular for the UDRS. SEM and SDD were respectively 6.36% and 17.72% for the BADS, 9.88% and 27.39% for the BFMMS, and 8.89% and 24.63% for the UDRS. High internal consistency was found. Pearson's correlations were high. Content validity showed insufficient accordance with the new CP definition and classification. Our results support the internal consistency and concurrent validity of the scales; however, taking into consideration the limitations in reliability, including the large SDD values and the content validity, further research on methods of assessment of dystonia is warranted.

Purpose The purpose of this study is to measure the psychometric properties of the Work and Wellbeing Inventory (WBI) (in Dutch: VAR-2), a screening tool that is used within occupational health care and rehabilitation. Our research question focused on the reliability and validity of this inventory. Methods Over the years seven different samples of workers, patients and sick listed workers varying in size between 89 and 912 participants (total: 2514), were used to measure the test-retest reliability, the internal consistency, the construct and concurrent validity, and the criterion and predictive validity. Results The 13 scales displayed good internal consistency and test-retest reliability. The constructive validity of the WBI could clearly be demonstrated in both patients and healthy workers. Confirmative factor analyses revealed a CFI >.90 for all scales. The depression scale predicted future work absenteeism (>6 weeks) because of a common mental disorder in healthy workers. The job strain scale and the illness behavior scale predicted long term absenteeism (>3 months) in workers with short-term absenteeism. The illness behavior scale moderately predicted return to work in rehab patients attending an intensive multidisciplinary program. Conclusions The WBI is a valid and reliable tool for occupational health practitioners to screen for risk factors for prolonged or future sickness absence. With this tool they will have reliable indications for further advice and interventions to restore the work ability.

Secondary traumatic stress and vicarious trauma: a validational study.

2002-10-01

Vicarious trauma (VT) and secondary traumatic stress (STS) or compassion fatigue both describe effects of working with traumatized persons on therapists. Despite conceptual similarities, their emphases differ: cognitive schemas vs. posttraumatic symptoms and burnout, respectively. The TSI Belief Scale (TSI-BSL) measures VT; the Compassion Fatigue Self-Test (CFST) for Psychotherapists measures STS. Neither has substantial psychometric evidence yet, nor has their association been studied. Results for 99 sexual assault and domestic violence counselors show concurrent validity between TSI-BSL and CFST, moderate convergence with burnout but useful discrimination, and strong convergence with general distress, but adequate independent shared variance. Counselors with interpersonal trauma histories scored higher on CFST, but not TSI-BSL or burnout, consistent with the CFST's emphasis on trauma symptomatology.

Influenza-like illnesses (ILI) cause paediatric morbidity and affect the quality of life (QoL) of children and their parents. We have developed a disease-specific questionnaire (Care-ILI-QoL) to measure the QoL of caregivers of children with ILI. The drafting of the Care-ILI-QoL questionnaire was based on a systematic review, a quantitative survey, qualitative interviews with parents, and meetings with paediatricians. Children aged 6-48 months recruited from childcare centres in Sydney, Australia, were followed up during the 2011 influenza season. Care-ILI-QoL and SF-12v2 Acute Form were administered to the parent of a sick child 2 weeks after the onset of ILI, and again 2 weeks after the child had recovered. Exploratory factor analysis was conducted. Internal consistency, concurrent validity, discriminant validity, homogeneity of items, and responsiveness were tested. Out of the 125 children enrolled from 48 childcare centres, 55 children had ILI (total 75 ILI episodes). Care-ILI-QoL was reduced from 25 to 16 items covering four factors: Daily Activities, Perceived Support, Social Life, and Emotions (Cronbach's alphas 0.90, 0.92, 0.78, and 0.72, respectively). Care-ILI-QoL has satisfactory concurrent and discriminant validity, good internal consistency, and excellent responsiveness. Total QoL and factor scores correlated well with SF-12v2 scores. Total QoL scores were significantly lower in parents who perceived their child as very/extremely sick, sacrificed 10 hours or more in work or recreation in caring for the child, or whose child had two or more general practitioner visits. Total QoL and factor scores were significantly higher after the child had recovered than when the child had ILI. Care-ILI-QoL is the first ILI-specific QoL instrument for parents and is demonstrated to be valid and reliable in a developed country setting where the child is affected by ILI. It has the potential to be applied in clinical and research settings to assist measurement of disease burden, as a needs assessment tool for resources or to inform policy changes.

The concurrent validity of the College Adjustment Scales was assessed using comparison to the College Maladjustment Scale of the Minnesota Multiphasic Inventory-2. Undergraduate students (N=56, 40 women, M age = 21.3 yr., 87.5% white, non-Hispanic) completed both tests. Analysis indicated scores on 8 of 9 College Adjustment Scales correlated significantly in the predicted direction with those on the College Maladjustment Scale, thereby providing some additional support for convergent validity. While the conclusions are limited significantly by the small sample, this report provides an incremental contribution to the validity of the College Adjustment Scales.

Lower limb isometric strength is a key parameter to monitor the training process or recognise muscle weakness and injury risk. However, valid and reliable methods to evaluate it often require high-cost tools. The aim of this study was to analyse the concurrent validity and reliability of a low-cost digital dynamometer for measuring isometric strength in lower limb. Eleven physically active and healthy participants performed maximal isometric strength for: flexion and extension of ankle, flexion and extension of knee, flexion, extension, adduction, abduction, internal and external rotation of hip. Data obtained by the digital dynamometer were compared with the isokinetic dynamometer to examine its concurrent validity. Data obtained by the digital dynamometer from 2 different evaluators and 2 different sessions were compared to examine its inter-rater and intra-rater reliability. Intra-class correlation (ICC) for validity was excellent in every movement (ICC > 0.9). Intra and inter-tester reliability was excellent for all the movements assessed (ICC > 0.75). The low-cost digital dynamometer demonstrated strong concurrent validity and excellent intra and inter-tester reliability for assessing isometric strength in the main lower limb movements.

2015-08-01

We developed a novel procedure specific simulation platform for robotic partial nephrectomy. In this study we prospectively evaluate its face, content, construct and concurrent validity. This hybrid platform features augmented reality and virtual reality. Augmented reality involves 3-dimensional robotic partial nephrectomy surgical videos overlaid with virtual instruments to teach surgical anatomy, technical skills and operative steps. Advanced technical skills are assessed with an embedded full virtual reality renorrhaphy task. Participants were classified as novice (no surgical training, 15), intermediate (less than 100 robotic cases, 13) or expert (100 or more robotic cases, 14) and prospectively assessed. Cohort performance was compared with the Kruskal-Wallis test (construct validity). Post-study questionnaire was used to assess the realism of simulation (face validity) and usefulness for training (content validity). Concurrent validity evaluated correlation between virtual reality renorrhaphy task and a live porcine robotic partial nephrectomy performance (Spearman's analysis). Experts rated the augmented reality content as realistic (median 8/10) and helpful for resident/fellow training (8.0-8.2/10). Experts rated the platform highly for teaching anatomy (9/10) and operative steps (8.5/10) but moderately for technical skills (7.5/10). Experts and intermediates outperformed novices (construct validity) in efficiency (p=0.0002) and accuracy (p=0.002). For virtual reality renorrhaphy, experts outperformed intermediates on GEARS metrics (p=0.002). Virtual reality renorrhaphy and in vivo porcine robotic partial nephrectomy performance correlated significantly (r=0.8, p <0.0001) (concurrent validity). This augmented reality simulation platform displayed face, content and construct validity. Performance in the procedure specific virtual reality task correlated highly with a porcine model (concurrent validity). Future efforts will integrate procedure specific virtual reality tasks and their global assessment. Copyright © 2015 American Urological Association Education and Research, Inc.

This study aims to investigate the concurrent validity and intrarater reliability of the Microsoft Kinect to measure thoracic kyphosis against the Flexicurve. Thirty-three healthy individuals (age: 31±11.0 years, men: 17, height: 170.2±8.2 cm, weight: 64.2±12.0 kg) participated, with 29 re-examined for intrarater reliability 1-7 days later. Thoracic kyphosis was measured using the Flexicurve and the Microsoft Kinect consecutively in both standing and sitting positions. Both the kyphosis index and angle were calculated. The Microsoft Kinect showed excellent concurrent validity (intraclass correlation coefficient=0.76-0.82) and reliability (intraclass correlation coefficient=0.81-0.98) for measuring thoracic kyphosis (angle and index) in both standing and sitting postures. This study is the first to show that the Microsoft Kinect has excellent validity and intrarater reliability to measure thoracic kyphosis, which is promising for its use in the clinical setting.

While fatigue after stroke is a common problem, it has no generally accepted definition. Our aim was to develop a case definition for post-stroke fatigue and to test its psychometric properties. A case definition with face validity and an associated structured interview was constructed. After initial piloting, the feasibility, reliability (test-retest and inter-rater) and concurrent validity (in relation to four fatigue severity scales) were determined in 55 patients with stroke. All participating patients provided satisfactory answers to all the case definition probe questions demonstrating its feasibility For test-retest reliability, kappa was 0.78 (95% CI, 0.57-0.94, P<.01) and for inter-rater reliability kappa was 0.80 (95% CI, 0.62-0.99, P<.01). Patients fulfilling the case definition also had substantially higher fatigue scores on four fatigue severity scales (P<.001) indicating concurrent validity. The proposed case definition is feasible to administer and reliable in practice, and there is evidence of concurrent validity. It requires further evaluation in different settings.

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).

We examine the psychometric properties of the Philadelphia Geriatric Morale Scale (PGMS) in an elderly Chinese population in Hong Kong. The study consisted of two cohorts: (a) 759 participants aged 70 years and older living in the community who were recruited as part of a territory-wide health survey and interviewed in 1993-1994; and (b) 388 participants living in long-term-care institutions in 1995-1996. Participants who were cognitively impaired (Abbreviated Mental Test score less than 7) or who could not answer questions for other reasons were excluded. The 15-item PGMS was administered. The Rasch dichotomous model was used to assess the validity of the PGMS, and the 15-item Geriatric Depression Scale, previously validated in Chinese, was also administered to examine the concurrent validity. A confirmatory factor analysis identified three underlying factors similar to findings among Caucasians; however, not all the goodness-of-fit indices were acceptable. An exploratory factor analysis using principal axis factoring and promax rotation revealed two underlying factors that explained 35% of the total variance: reconciled aging and unstrained affect. Some items were redundant when applied to the institutional sample. Concurrent validity was demonstrated by the good correlation between the reconciled aging and unstrained affect domains and the Geriatric Depression Scale (r = -0.72 and r = -0.56 respectively). Female gender, older age, and residence in institutions were associated with lower morale. The PGMS is a valid quality-of-life measure in elderly Hong Kong Chinese persons, but its psychometric properties are slightly different from those for Caucasians.

The aim of the present study was to create a translated version of the Pediatric Quality of Life Inventory™ 3.0 Diabetes Module (PedsQL™ 3.0 Diabetes Module) in Brazilian Portuguese that was conceptually equivalent to the original American English version and to linguistically validate it in a Brazilian pediatric population with type 1 diabetes mellitus and their parents or caregivers. The instrument was translated, back-translated, and then administered to 83 children/adolescents (5-18 years) with type 1 diabetes mellitus and their family members and to 25 parents/caregivers of patients aged between 2 and 4 years. The final translated version was tested for reliability by analyzing internal consistency, intraobserver (test-retest) reliability, and concurrent validity. Cronbach's alpha coefficient for the total score of the questionnaires of children/adolescents (α=0.85) and their parents (α=0.82) was above the recommended minimum of 0.70 for group comparisons. Intraobserver reliability and concurrent validity exhibited a significant positive correlation (p<0.001), indicating the reliability of the translated instrument. A moderate but significant positive correlation (r=0.40; p<0.001) was demonstrated between the total scores of patient self-report and parent proxy-report scales. There was no significant correlation between glycated hemoglobin (HbA1c) levels and the respective scores in the questionnaires answered by patients and their parents/caregivers. The analysis of the translated version of the PedsQL™ 3.0 Diabetes Module revealed adequate psychometric characteristics with respect to reliability and validity following administration to a sample of Brazilian children/adolescents with type 1 diabetes mellitus and their caregivers.

Assessing parent affect is important because studies examining the parent-child dyad have shown that parent affect has a profound impact on parent-child interactions and related outcomes. Although some measures that assess general affect during daily lives exist, to date there are only few tools that assess parent affect in the context of feeding. The aim of this study was to develop an instrument to measure parent affect specific to the feeding context and determine its validity and reliability. A brief instrument consisting of 20 items was developed that specifically asks how parents feel during the feeding process. This brief instrument draws on the structure of a well-validated general affect measure. A total of 296 Hispanic and Black Head Start parents of preschoolers completed the Feeding Emotions Scale along with other parent-report measures as part of a larger study designed to better understand feeding interactions during the dinner meal. Confirmatory factor analysis supported a two-factor model with independent subscales of positive affect and negative affect (Cronbach's alphas of 0.85 and 0.84, respectively). Concurrent and convergent construct validity was evaluated by correlating the subscales of the Feeding Emotions Scale with positive emotionality and negative emotionality from the Differential Emotions Scale - a measure of general adult emotions. Concurrent and convergent criterion validity was evaluated by testing mean differences in affect across parent feeding styles using ANOVA. A significant difference was found across maternal weight status for positive feeding affect. The resulting validated measure can be used to assess parent affect in studies of feeding to better understand how interactions during feeding may impact the development of child eating behaviors and possibly weight status.

Computerized neuropsychological tests are effective in assessing different cognitive domains, but are often limited by the need of proprietary hardware and technical staff. Web-based tests can be more accessible and flexible. We aimed to investigate validity, effects of computer familiarity, education, and age, and the feasibility of a new web-based self-administered neuropsychological test battery (Memoro) in older adults and seniors. A total of 62 (37 female) participants (mean age 60.7 years) completed the Memoro web-based neuropsychological test battery and a traditional battery composed of similar tests intended to measure the same cognitive constructs. Participants were assessed on computer familiarity and how they experienced the two batteries. To properly test the factor structure of Memoro, an additional factor analysis in 218 individuals from the HUNT population was performed. Comparing Memoro to traditional tests, we observed good concurrent validity (r = .49-.63). The performance on the traditional and Memoro test battery was consistent, but differences in raw scores were observed with higher scores on verbal memory and lower in spatial memory in Memoro. Factor analysis indicated two factors: verbal and spatial memory. There were no correlations between test performance and computer familiarity after adjustment for age or age and education. Subjects reported that they preferred web-based testing as it allowed them to set their own pace, and they did not feel scrutinized by an administrator. Memoro showed good concurrent validity compared to neuropsychological tests measuring similar cognitive constructs. Based on the current results, Memoro appears to be a tool that can be used to assess cognitive function in older and senior adults. Further work is necessary to ascertain its validity and reliability.

The Memorial Anxiety Scale for Prostate Cancer (MAX-PC) was developed to identify and assess cancer-specific anxiety among men with prostate cancer (PCa); however, there is no Chinese version. The aim of our study was to translate the English version of MAX-PC into Chinese and evaluate the psychometric properties of it. The study cohort comprised 254 participants. Internal consistency including the Cronbach's alpha coefficient and item-total correlations were used to measure the reliability of the scale. Factor structure was analyzed by exploratory factor analysis and concurrent validity by comparing MAX-PC scores with anxiety subscale scores of the Hospital Anxiety and Depression Scale (HADS). Divergent validity was assessed by correlating MAX-PC with HADS depression subscale, while discriminant ability by comparing differences in MAX-PC scores between different patient groups. The Chinese version of MAX-PC demonstrated good reliability; the Cronbach's alpha coefficient for the total and three subscales (prostate cancer anxiety, PSA anxiety, and fear of recurrence) being 0.94, 0.93, 0.82, and 0.85, respectively. Exploratory factor analysis supported the three-factor structure of the scale established in the original version. Despite the somewhat underperformed divergent validity, the scale demonstrated good concurrent validity with a strong correlation with the HADS anxiety subscale (r = 0.71, p < 0.01). Moreover, discriminant ability was demonstrated by ability to differentiate between disease stages. The MAX-PC Chinese version was confirmed to be a valid, reliable instrument and is thus appropriate for identifying and quantifying cancer-specific anxiety in Chinese PCa patients.

DSM-IV criteria for ADHD specify two dimensions of inattention and hyperactivity-impulsivity symptoms that are used to define three nominal subtypes: predominantly hyperactive-impulsive type (ADHD-H), predominantly inattentive type (ADHD-I), and combined type (ADHD-C). To aid decision-making for DSM-5 and other future diagnostic systems, a comprehensive literature review and meta-analysis of 546 studies was completed to evaluate the validity of the DSM-IV model of ADHD. Results indicated that DSM-IV criteria identify individuals with significant and persistent impairment in social, academic, occupational, and adaptive functioning when intelligence, demographic factors, and concurrent psychopathology are controlled. Available data overwhelmingly support the concurrent, predictive, and discriminant validity of the distinction between inattention and hyperactivity-impulsivity symptoms, and indicate that nearly all differences among the nominal subtypes are consistent with the relative levels of inattention and hyperactivity-impulsivity symptoms that define the subtypes. In contrast, the validity of the DSM-IV subtype model is compromised by weak evidence for the validity of ADHD-H after first grade, minimal support for the distinction between ADHD-I and ADHD-C in studies of etiological influences, academic and cognitive functioning, and treatment response, and the marked longitudinal instability of all three subtypes. Overall, it is concluded that the DSM-IV ADHD subtypes provide a convenient clinical shorthand to describe the functional and behavioral correlates of current levels of inattention and hyperactivity-impulsivity symptoms, but do not identify discrete subgroups with sufficient long-term stability to justify the classification of distinct forms of the disorder. Empirical support is stronger for an alternative model that would replace the subtypes with dimensional modifiers that reflect the number of inattention and hyperactivity-impulsivity symptoms at the time of assessment.

The Psychosocial Assessment of Candidates for Transplantation (PACT) is a validated instrument for evaluating psychosocial risk factors in transplant candidates. This study examined reliability and validity of the Japanese version of the PACT (J-PACT). PACT is a clinician-rated scale consisting of an initial rating, 8 subscales, and a final rating. J-PACT was developed through a translation and back-translation procedure. Seventy adult patients who underwent allogeneic hematopoietic stem cell transplant between April 2009 and December 2013 received retrospective J-PACT ratings based on medical records. Interrater reliability and concurrent validity with Hospital Anxiety and Depression Scale (HADS) and Profile of Mood Status (POMS) scores were assessed. Interrater reliability for each J-PACT item was generally high, ranging from 0.53 (drug and alcohol use)-0.93 (support stability). The concurrent validity analyses revealed the following significant relationships (p < 0.05). Higher support stability was associated with lower HADS depression (p = 0.02), POMS anger (p = 0.001), POMS fatigue (p = 0.03), and POMS confusion (p = 0.01) scores. Higher support availability was associated with lower POMS anger scores (p = 0.01). More suitable personality was associated with lower HADS anxiety (p = 0.04) and HADS depression (p = 0.048) scores. Better scores on lifestyle factors and alcohol use were both associated with lower POMS confusion scores (p = 0.01, 0.04, respectively). Better final rating was associated with lower HADS anxiety (p = 0.03) and HADS depression (p = 0.02) scores. J-PACT was reliable and valid, although further study is needed to confirm these findings.

This study provides information on how two standardized measures based on different theoretical frameworks can be used in collecting information on motor development and performance in 4- and 5-year-olds with autism spectrum disorder (ASD). The purpose of the study was to determine the concurrent validity of the Miller Function and Participation Scales (M-FUN) with the Peabody Developmental Motor Scales, Second Edition (PDMS-2) in young children with ASD. The gross motor sections of the PDMS-2 and the M-FUN were administered to 22 children with ASD between the ages of 48 and 71 months. Concurrent validity between overall motor scores and agreement in identification of motor delay were assessed. A very strong correlation (Pearson's r =.851) was found between the M-FUN scale scores and the PDMS-2 gross motor quotients (GMQs). Strong agreement in identification of children with average motor skills and delayed motor skills at 1.5 standard deviations below the mean was also found. This study supports the concurrent validity of the M-FUN with the PDMS-2 for young children with ASD. While both tests provide information regarding motor delay, the M-FUN may provide additional information regarding the neurological profile of the child.

The Dysphagia Handicap Index (DHI) is a 25-item questionnaire assessing the physical, functional, and emotional aspects of dysphagia patients' quality of life (QoL). The study goal was to translate and validate the Hebrew-DHI. 148 patients undergoing fiberoptic endoscopic examination of swallowing (FEES) in two specialized dysphagia clinics between February and August 2017 filled the Hebrew-DHI and self-reported their dysphagia severity on a scale of 1-7. 21 patients refilled the DHI during a 2-week period following their first visit. FEES were scored for residue (1 point per consistency), penetration and aspiration (1 point for penetration, 2 points for aspiration, per consistency). 51 healthy volunteers also filled the DHI. Internal consistency and test-retest reproducibility were used for reliability testing. Validity was established by comparing DHI scores of dysphagia patients and healthy controls. Concurrent validity was established by correlating the DHI score with the FEES score. Internal consistency of the Hebrew-DHI was high (Cronbach's alpha = 0.96), as was the test-retest reproducibility (Spearman's correlation coefficient = 0.82, p < 0.001). The Hebrew-DHI's total score, and its three subscales (physical/functional/emotional) were significantly higher in dysphagia patients compared to those in healthy controls (median 38 pts, IQR 18-56 for dysphagia patients compared to 0, IQR 0-2 for healthy controls, p < 0.0001). A strong correlation was observed between the DHI score and the self-reported dysphagia severity measure (Spearman's correlation coefficient = 0.88, p < 0.0001). A moderate correlation was found between the DHI score and the FEES score (Pearson's correlation coefficient = 0.245, p = 0.003). The Hebrew-DHI is a reliable and valid questionnaire assessing dysphagia patients' QoL.

The aim of this study was to determine the reliability and concurrent validity of commonly used physical performance tests using the OmniVR Virtual Rehabilitation System for healthy community-dwelling elders. Participants (N = 40) were recruited by the authors and were screened for eligibility. The initial method of measurement was randomized to either virtual reality (VR) or clinically based measures (CM). Physical performance tests included the five times sit to stand, Timed Up and Go (TUG), Forward Functional Reach (FFR) and 30-s stand test. A random number generator determined the testing order. The test-re-test reliability for the VR and CM was determined. Furthermore, concurrent validity was determined using a Pearson product moment correlation (Pearson r). The VR demonstrated excellent reliability for 5 × STS intraclass correlation coefficient (ICC) = 0.931(3,1), FFR ICC = 0.846(3,1) and the TUG ICC = 0.944(3,1). The concurrent validity data for the VR and CM (ICC 3, k) were moderate for FFR ICC = 0.682, excellent 5 × STS ICC = 0.889 and excellent for the TUG ICC = 0.878. The concurrent validity of the 30-s stand test was good ICC = 0.735(3,1). This study supports the use of VR equipment for measuring physical performance tests in the clinic for healthy community-dwelling elders. Virtual reality equipment is not only used to treat balance impairments but it is also used to measure and determine physical impairments through the use of physical performance tests. Virtual reality equipment is a reliable and valid tool for collecting physical performance data for the 5 × STS, FFR, TUG and 30-s stand test for healthy community-dwelling elders.

1982-01-01

An effective data collection methodology for evaluating software development methodologies was applied to four different software development projects. Goals of the data collection included characterizing changes and errors, characterizing projects and programmers, identifying effective error detection and correction techniques, and investigating ripple effects. The data collected consisted of changes (including error corrections) made to the software after code was written and baselined, but before testing began. Data collection and validation were concurrent with software development. Changes reported were verified by interviews with programmers.

Low hand grip strength is a strong predictor for both long-term and short-term disability and mortality. The Nintendo Wii Balance Board (WBB) is an inexpensive, portable, wide-spread instrument with the potential for multiple purposes in assessing clinically relevant measures including muscle strength. The purpose of the study was to explore intrarater reliability and concurrent validity of the WBB by comparing it to the Jamar hand dynamometer. Intra-rater test-retest cohort design with randomized validity testing on the first session. Using custom WBB software, thirty old adults (69.0 ± 4.2 years of age) were studied for reproducibility and concurrent validity compared to the Jamar hand dynamometer. Reproducibility was tested for dominant and non-dominant hands during the same time-of-day, one week apart. Intraclass correlation coefficient (ICC) and standard error of measurement (SEM) and limits of agreement (LOA) were calculated to describe relative and absolute reproducibility respectively. To describe concurrent validity, Pearson's product-moment correlation and ICC was calculated. Reproducibility was high with ICC values of >0.948 across all measures. Both SEM and LOA were low (0.2-0.5 kg and 2.7-4.2 kg, respectively) in both the dominant and non-dominant hand. For validity, Pearson correlations were high (0.80-0.88) and ICC values were fair to good (0.763-0.803). Reproducibility for WBB was high for relative measures and acceptable for absolute measures. In addition, concurrent validity between the Jamar hand dynamometer and the WBB was acceptable. Thus, the WBB may be a valid instrument to assess hand grip strength in older adults.

To investigate the concurrent, face and content validity of an evaluation tool for Myofascial Adhesions in Patients after Breast Cancer (MAP-BC evaluation tool). 1) Concurrent validity of the MAP-BC evaluation tool was investigated by exploring correlations (Spearman's rank Correlation Coefficient) between the subjective scores (0 -no adhesions to 3 -very strong adhesions) of the skin level using the MAP-BC evaluation tool and objective elasticity parameters (maximal skin extension and gross elasticity) generated by the Cutometer Dual MPA 580. Nine different examination points on and around the mastectomy scar were evaluated. 2) Face and content validity were explored by questioning therapists experienced with myofascial therapy in breast cancer patients about the comprehensibility and comprehensiveness of the MAP-BC evaluation tool. 1) Only three meaningful correlations were found on the mastectomy scar. For the most lateral examination point on the mastectomy scar a moderate negative correlation (-0.44, p = 0.01) with the maximal skin extension and a moderate positive correlation with the resistance versus ability of returning or 'gross elasticity' (0.42, p = 0.02) were found. For the middle point on the mastectomy scar an almost moderate positive correlation with gross elasticity was found as well (0.38, p = 0.04) 2) Content and face validity have been found to be good. Eighty-nine percent of the respondent found the instructions understandable and 98% found the scoring system obvious. Thirty-seven percent of the therapists suggested to add the possibility to evaluate additional anatomical locations in case of reconstructive and/or bilateral surgery. The MAP-BC evaluation tool for myofascial adhesions in breast cancer patients has good face and content validity. Evidence for good concurrent validity of the skin level was found only on the mastectomy scar itself.

Musculoskeletal disorders (MSD) are nowadays seen within a biopsychosocial framework, including salutogenic factors, motivation factors, and coping ability. Such a framework recognizes the importance of motivational factors in health promotion and in rehabilitation. The Motivation for Change Questionnaire (MCQ) has been developed to measure the strength of individuals' motivation for change in life, MCQ part 1, and work situation, MCQ part 2. The purpose of the study was to test the content and concurrent validity of the MCQ on patients with prolonged musculoskeletal disorders referred to interdisciplinary rehabilitation as a basis for use in medical and occupational rehabilitation. Content validity was studied among an expert group of 20 rehabilitation professionals at a rehabilitation centre, and with 10 individuals suffering from prolonged MSD in the south of Sweden. The experts evaluated the clinical relevance of each question in MCQ. Concurrent validity was studied on 58 patients with prolonged MSD at an interdisciplinary rehabilitation centre in the south of Sweden. They answered MCQ, QPS Nordic questionnaire, KASAM and the Action theory questionnaire. Spearman's rank correlation coefficient was used in the analyses. The MCQ covered and measured areas of relevance according to content validity. No floor effects in any of the subscales of MCQ part 1 were seen. In MCQ part 2, floor effects were seen in two sub indexes. As for concurrent validity subscales of MCQ correlated significantly with QPS Nordic questionnaire and KASAM. Findings so far indicate the instrument to be valid for use within the present patient group. The questionnaire can be used to identify patient's motivating factors for change in life and work, as a basis for motivational work within rehabilitation.

The purpose of this study was to investigate the psychometric properties of the modified Thai Spiritual Well-Being Scale in patients with advanced cancer. This cross-sectional study was employed to investigate psychometric properties. Some 196 participants from three tertiary hospitals in Bangkok and suburban Thailand were asked to complete a Personal Information Questionnaire (PIQ), The Memorial Symptom Assessment Scale (MSAS), and the Spiritual Well-Being Scale (SWBS). Validity was determined by known-group, concurrent, and constructs validity. Reliability was estimated using internal consistency by Cronbach's α coefficients. Three factors were extracted: so-called existential well-being, religious well-being, and peacefulness accounted for 71.44% of total variance. The Cronbach's α coefficients for total SWB, EWB, RWB, and peacefulness were 0.96, 0.94, and 0.93, respectively. These findings indicate that the Thai SWBS is a valid and reliable instrument, and it presented one more factor than the original version.

Cyberchondria is a form of anxiety characterised by excessive online health research. It may lead to increased levels of psychological distress, worry, and unnecessary medical expenses. The aim of the present study was to develop a psychometrically sound measure of this dimension. A sample of undergraduate students (N = 208; 64% female) completed a pilot version of the cyberchondria severity scale (CSS) along with the short form version of the depression, anxiety and stress scale (DASS-21). Exploratory factor analysis identified a correlated five factor structure that were labelled 'Compulsion', 'Distress', 'Excessiveness', 'Reassurance Seeking' and 'Mistrust of Medical Professional'. The CSS demonstrated good psychometric properties; the subscales had high internal consistency, along with good concurrent and convergent validity. The CSS may prove useful in a wide variety of future research activities. It may also facilitate the development and validation of interventions for cyberchondria. Copyright © 2014 Elsevier Ltd.

This study was done to test the psychometric properties of the modified version of the Sport Motivation Scale adapted for children in physical education. Participants were elementary school students (N = 452, M(age) = 13.9 +/- 1.04) who responded to the Sport Motivation Scale for Children. The scale assesses three types of motivation at the contextual level, namely, Intrinsic Motivation, Extrinsic Motivation, and Amotivation. Results supported the construct validity (CFI = .95), and internal consistency of the scale (Cronbach alpha > .65). Correlations indicated Sport Motivation Scale for Children simplex pattern exhibiting higher correlations among adjacent subscales than subscales farther apart. The concurrent validity, examined through correlations with scores on the Physical Self-description Questionnaire was satisfactory. Sex differences were examined to assess the discriminant validity. Boys were more intrinsically motivated than girls. Overall, the scale seems a useful one for assessment of motivation in physical education.

Goal of the present study was the validation of a German version of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E). 197 adult epilepsy patients completed the NDDI-E (185 completed both the NDDI-E and BDI). 95 patients received psychiatric consults. 33 patients received a diagnosis of major depression according to ICD-10 criteria. Internal consistency of the NDDI-E was .83. Receiver operating characteristics (ROC) showed an area under the curve of 0.92. Applying a cutoff score of ≥14 resulted in both sensitivity and specificity of 0.85. In the subsample with psychiatric consult, at the same optimal cutoff, sensitivity was 0.92, and specificity was 0.86. Further analyses showed a high concurrent validity with the BDI. The German version of the NDDI-E constitutes a brief and reliable depression screening instrument for epilepsy patients. Copyright © 2012 Elsevier Inc. All rights reserved.

Virtual reality (VR) laparoscopic simulators have been around for more than 10 years and have proven to be cost- and time-effective in laparoscopic skills training. However, most simulators are, in our experience, considered less interesting by residents and are often poorly accessible. Consequently, these devices are rarely used in actual training. In an effort to make a low-cost and more attractive simulator, a custom-made Nintendo Wii game was developed. This game could ultimately be used to train the same basic skills as VR laparoscopic simulators ought to. Before such a video game can be implemented into a surgical training program, it has to be validated according to international standards. The main goal of this study was to test construct and concurrent validity of the controls of a prototype of the game. In this study, the basic laparoscopic skills of experts (surgeons, urologists, and gynecologists, n = 15) were compared to those of complete novices (internists, n = 15) using the Wii Laparoscopy (construct validity). Scores were also compared to the Fundamentals of Laparoscopy (FLS) Peg Transfer test, an already established assessment method for measuring basic laparoscopic skills (concurrent validity). Results showed that experts were 111 % faster (P = 0.001) on the Wii Laparoscopy task than novices. Also, scores of the FLS Peg Transfer test and the Wii Laparoscopy showed a significant, high correlation (r = 0.812, P < 0.001). The prototype setup of the Wii Laparoscopy possesses solid construct and concurrent validity.

The current study examined whether the Avoidance and Fusion Questionnaire for Youth (AFQ-Y; L. A. Greco, W. Lambert, & R. A. Baer, 2008), a self-report measure of psychological inflexibility for children and adolescents, might be useful for measuring psychological inflexibility for adults. The psychometric properties of the AFQ-Y were examined using data from a college student sample (N = 387) and a clinical sample of patients with anxiety disorders (N = 115). The AFQ-Y, but not the Acceptance and Action Questionnaire-II (AAQ-II; F. W. Bond et al., in press), demonstrated a reading level at or below the recommended 5th or 6th grade reading level. The AFQ-Y also demonstrated adequate reliability (internal consistency), factorial validity, convergent and discriminant validity, and concurrent validity predicting psychological symptoms. Moreover, the AFQ-Y showed incremental validity over the AAQ-II in predicting several psychological symptom domains. Implications for the assessment of psychological inflexibility are discussed.

Kluger, Benzi M; Garimella, Sanjana; Garvan, Cynthia

2017-10-01

Fatigue is a common and debilitating symptom of Parkinson's disease (PD) with no evidence-based treatments. While several fatigue scales are partially validated in PD the minimal clinically important difference (MCID) is unknown for any scale but is an important psychometric value to design and interpret therapeutic trials. We thus sought to determine the MCID for the Modified Fatigue Impact Scale (MFIS). This is a secondary data analysis from 94 PD participants in an acupuncture trial for PD fatigue. Standard psychometric approaches were used to establish validity and an anchor-based approach was used to determine the MCID. The MFIS demonstrated good concurrent validity with other outcome measures and high internal consistency. MCIDs values were found to be 13.8, 6.8 and 6.2 for the MFIS total, MFIS cognitive, and MFIS physical subscores respectively. The MFIS is a valid multidimensional measure of fatigue in PD with demonstrable MCID. Copyright © 2017 Elsevier Ltd. All rights reserved.

This study reports the validation of the Hong Kong version of Oxford Cognitive Screen (HK-OCS). Seventy Cantonese-speaking healthy individuals participated to establish normative data and 46 chronic stroke survivors were assessed using the HK-OCS, Albert's Test of Visual Neglect, short test of gestural production, and Hong Kong version of the following assessments: Western Aphasia Battery, MMSE, MoCA, Modified Barthel Index, and Lawton Instrumental Activities of Daily Living scale. The validity of the HK-OCS was appraised by the difference between the two participant groups. Neurologically unimpaired individuals performed significantly better than stroke survivors on the HK-OCS. Positive and significant correlations found between cognitive subtests in the HK-OCS and related assessments indicated good concurrent validity. Excellent intra-rater and inter-rater reliabilities, fair test-retest reliability, and acceptable internal consistency suggested that the HK-OCS had good reliability. Specific HK-OCS subtests including semantics, episodic memory, number writing, and orientation were the best predictors of functional outcomes.

The Illusory Beliefs Inventory: a new measure of magical thinking and its relationship with obsessive compulsive disorder.

Kingdon, Bianca L; Egan, Sarah J; Rees, Clare S

2012-01-01

Magical thinking has been proposed to have an aetiological role in obsessive compulsive disorder (OCD). To address the limitations of existing measures of magical thinking we developed and validated a new 24-item measure of magical thinking, the Illusory Beliefs Inventory (IBI). The validation sample comprised a total of 1194 individuals across two samples recruited via an Internet based survey. Factor analysis identified three subscales representing domains relevant to the construct of magical thinking: Magical Beliefs, Spirituality, and Internal State and Thought Action Fusion. The scale had excellent internal consistency and evidence of convergent and discriminant validity. Evidence of criterion-related concurrent validity confirmed that magical thinking is a cognitive domain associated with OCD and is largely relevant to neutralizing, obsessing and hoarding symptoms. It is important for future studies to extend the evidence of the psychometric properties of the IBI in new populations and to conduct longitudinal studies to examine the aetiological role of magical thinking.

The DSM-5 Section III proposes a hybrid dimensional-categorical model of conceptualizing personality and its disorders that includes assessment of impairments in personality functioning (criterion A) and maladaptive personality traits (criterion B). The Personality Inventory for the DSM-5 is a new dimensional tool, composed of 220 items organized into 25 facets that delineate five higher order domains of clinically relevant personality differences, and was developed to operationalize the DSM-5 model of pathological personality traits. The current studies address the internal consistency (study 1), the test-retest reliability (study 2) and the criterion validity (studies 3 and 4) of the Portuguese version of the PID-5 in samples of native speaking psychology students. Results indicated good internal consistency reliabilities and good temporal stability reliabilities for the majority of the PID-5 traits. The correlational pattern of the PID-5 traits with two measures of personality was in accordance with theoretical expectations and showed its concurrent validity. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

To verify the concurrent validity and interobserver reliability of the Alberta Infant Motor Scale (AIMS) in premature infants followed-up at the outpatient clinic of Instituto Fernandes Figueira, Fundação Oswaldo Cruz (IFF/Fiocruz), in Rio de Janeiro, Brazil. A total of 88 premature infants were enrolled at the follow-up clinic at IFF/Fiocruz, between February and December of 2006. For the concurrent validity study, 46 infants were assessed at either 6 (n = 26) or 12 (n = 20) months' corrected age using the AIMS and the second edition of the Bayley Scales of Infant Development, by two different observers, and applying Pearson's correlation coefficient to analyze the results. For the reliability study, 42 infants between 0 and 18 months were assessed using the Alberta Infant Motor Scale, by two different observers and the results analyzed using the intraclass correlation coefficient. The concurrent validity study found a high level of correlation between the two scales (r = 0.95) and one that was statistically significant (p < 0.01) for the entire population of infants, with higher values at 12 months (r = 0.89) than at 6 months (r = 0.74). The interobserver reliability study found satisfactory intraclass correlation coefficients at all ages tested, varying from 0.76 to 0.99. The AIMS is a valid and reliable instrument for the evaluation of motor development in high-risk infants within the Brazilian public health system.

The Microsoft Xbox One Kinect™ (Kinect V2) contains a depth camera that can be used to manually identify anatomical landmark positions in three-dimensions independent of the standard skeletal tracking, and therefore has potential for low-cost, time-efficient three-dimensional movement analysis (3DMA). This study examined inter-session reliability and concurrent validity of the Kinect V2 for the assessment of coronal and sagittal plane kinematics for the trunk, hip and knee during single leg squats (SLS) and drop vertical jumps (DVJ). Thirty young, healthy participants (age = 23 ± 5yrs, male/female = 15/15) performed a SLS and DVJ protocol that was recorded concurrently by the Kinect V2 and 3DMA during two sessions, one week apart. The Kinect V2 demonstrated good to excellent reliability for all SLS and DVJ variables (ICC ≥ 0.73). Concurrent validity ranged from poor to excellent (ICC = 0.02 to 0.98) during the SLS task, although trunk, hip and knee flexion and two-dimensional measures of knee abduction and frontal plane projection angle all demonstrated good to excellent validity (ICC ≥ 0.80). Concurrent validity for the DVJ task was typically worse, with only two variables exceeding ICC = 0.75 (trunk and hip flexion). These findings indicate that the Kinect V2 may have potential for large-scale screening for ACL injury risk, however future prospective research is required.

Heterogeneity of psychosis presents significant challenges for classification. Between 2 and 12 symptom dimensions have been proposed, and consensus is lacking. The present study sought to identify uniquely informative models by comparing the validity of these alternatives. An epidemiologic cohort of 628 first-admission inpatients with psychosis was interviewed 6 times over 2 decades and completed an electrophysiological assessment of error processing at year 20. We first analyzed a comprehensive set of 49 symptoms rated by interviewers at baseline, progressively extracting from 1 to 12 factors. Next, we compared the ability of resulting factor solutions to (a) account for concurrent neural dysfunction and (b) predict 20-year role, social, residential, and global functioning, and life satisfaction. A four-factor model showed incremental validity with all outcomes, and more complex models did not improve explanatory power. The 4 dimensions-reality distortion, disorganization, inexpressivity, and apathy/asociality-were replicable in 5 follow-ups, internally consistent, stable across assessments, and showed strong discriminant validity. These results reaffirm the value of separating disorganization and reality distortion, are consistent with recent findings distinguishing inexpressivity and apathy/asociality, and suggest that these 4 dimensions are fundamental to understanding neural abnormalities and long-term outcomes in psychosis.

The lumbar multifidus muscle provides an important contribution to lumbar spine stability, and the restoration of lumbar multifidus function is a frequent goal of rehabilitation. Currently, there are no reliable and valid physical examination procedures available to assess lumbar multifidus function among patients with low back pain. To examine the inter-rater reliability and concurrent validity of the multifidus lift test (MLT) to identify lumbar multifidus dysfunction among patients with low back pain. A cross-sectional analysis of reliability and concurrent validity performed in a university outpatient research facility. Thirty-two persons aged 18 to 60 years with current low back pain and a minimum modified Oswestry disability score of 20%. Study participants were excluded if they reported a history of lumbar spine surgery, lumbar radiculopathy, medical red flags, osteoporosis, or had recently been treated with spinal manipulation or trunk stabilization exercises. Concurrent measures of lumbar multifidus muscle function at the L4-L5 and L5-S1 levels were obtained with the MLT (index test) and real-time ultrasound imaging (reference standard). The inter-rater reliability of the MLT was examined by measuring the level of agreement between two blinded examiners. Concurrent validity of the MLT was investigated by comparing clinicians' judgments with real-time ultrasound imaging measures of lumbar multifidus function. Inter-rater reliability of the MLT was substantial to excellent (κ=0.75 to 0.81, p≤.01) and free from errors of bias and prevalence. When performed at L4-L5 or L5-S1, the MLT demonstrated evidence of concurrent validity through its relationship with the reference standard results at L4-L5 (rbis=0.59-0.73, p≤.01). The MLT generally failed to demonstrate a relationship with the reference standard results from the L5-S1 level. Our results provide preliminary evidence supporting the reliability and validity of the MLT to assess lumbar multifidus function at the L4-L5 spinal level. Additional research examining the measurement properties and utility of this test should be undertaken before confident implementation with patients. Copyright © 2015 Elsevier Inc.

This study aimed to assess the validity and reliability of the Turkish version of Diagnostic and Statistical Manual of Mental Disorders (DSM-5) Level 2 Anger Scale. The scale was prepared by translation and back translation of DSM-5 Level 2 Anger Scale. Study groups consisted of a clinical sample of cases diagnosed with depressive disorder and treated in a child and adolescent psychiatry unit and a community sample. The study was continued with 218 children and 160 parents. In the assessment process, child and parent forms of DSM-5 Level 2 Anger Scale and Children's Depression Inventory and Strengths and Difficulties Questionnaire-Parent Form were used. In the reliability analyses, the Cronbach alpha internal consistency coefficient values were found very high regarding child and parent forms. Item-total score correlation coefficients were high and very high, respectively, for child and parent forms indicating a statistical significance. As for construct validity, one factor was maintained for each form and was found to be consistent with the original form of the scale. As for concurrent validity, the child form of the scale showed significant correlation with Children's Depression Inventory, while the parent form showed significant correlation with Strengths and Difficulties Questionnaire-Parent Form. It was found that the Turkish version of DSM-5 Level 2 Anger Scale could be utilized as a valid and reliable tool both in clinical practice and for research purposes.

This study aimed to assess the validity and reliability of the Turkish version of the Diagnostic and statistical manual of Mental Disorders. (5 th ed.) (DSM-5) Social Anxiety Disorder Severity Scale- Child Form. The scale was prepared by carrying out the translation and back translation of the DSM-5 Social Anxiety Disorder Severity Scale - Child Form. The study group consisted of 31 patients that had been treated in a child psychiatry unit and diagnosed with social anxiety disorder and 99 healthy volunteers that were attending middle or high school during the study period. For the assessment, the Screen for Child Anxiety and Related Emotional Disorders (SCARED) was also used along with the DSM-5 Social Anxiety Disorder Severity Scale - Child Form. Regarding reliability analyses, Cronbach's alpha internal consistency coefficient was calculated as 0.941, while item-total score correlation coefficients were measured between 0.566 and 0.866. A test-retest correlation coefficient was calculated as r=0.711. As for construct validity, one factor that could explain 66.0 % of the variance was obtained. As for concurrent validity, the scale showed a high correlation with the SCARED. It was concluded that the Turkish version of the DSM-5 Social Anxiety Disorder Severity Scale - Child Form could be utilized as a valid and reliable tool both in clinical practice and for research purposes.

Nurses and other healthcare workers frequently experience belief conflict, one of the most important, new stress-related problems in both academic and clinical fields. In this study, using a sample of 1,683 nursing practitioners, we developed The Assessment of Belief Conflict in Relationship-14 (ABCR-14), a new scale that assesses belief conflict in the healthcare field. Standard psychometric procedures were used to develop and test the scale, including a qualitative framework concept and item-pool development, item reduction, and scale development. We analyzed the psychometric properties of ABCR-14 according to entropy, polyserial correlation coefficient, exploratory factor analysis, confirmatory factor analysis, average variance extracted, Cronbach's alpha, Pearson product-moment correlation coefficient, and multidimensional item response theory (MIRT). The results of the analysis supported a three-factor model consisting of 14 items. The validity and reliability of ABCR-14 was suggested by evidence from high construct validity, structural validity, hypothesis testing, internal consistency reliability, and concurrent validity. The result of the MIRT offered strong support for good item response of item slope parameters and difficulty parameters. However, the ABCR-14 Likert scale might need to be explored from the MIRT point of view. Yet, as mentioned above, there is sufficient evidence to support that ABCR-14 has high validity and reliability. The ABCR-14 demonstrates good psychometric properties for nursing belief conflict. Further studies are recommended to confirm its application in clinical practice.

Social support plays a crucial role in the treatment and recovery process of patients engaging in methadone maintenance treatment (MMT). However, there is a paucity of research about social support among MMT patients, possibly due to a lack of appropriate measuring tools. This study aimed to evaluate the psychometric properties of the Vietnamese version of the Medical Outcomes Study: Social Support Survey (MOS-SSS) among MMT patients. A cross-sectional survey of 300 patients was conducted in a methadone clinic in Ho Chi Minh City, Vietnam. MMT patients who agreed to participate in the study completed a face-to-face interview in a private room. The MOS-SSS was translated into Vietnamese using standard forward-backward process. Internal consistency was measured by Cronbach's alpha. The intra-class correlation coefficient was used to determine the test-retest reliability of the MOS-SSS in 75 participants two weeks after the first survey. Concurrent validity of the MOS-SSS was evaluated by correlations with the Multidimensional Scale of Perceived Social Support (MSPSS) and the Perceived Stigma of Addiction Scale (PSAS). Construct validity was investigated by confirmatory factor analysis. The MOS-SSS had good internal consistency with Cronbach's alpha from 0.95 to 0.97 for the four subscales and 0.97 for the overall scale. The two-week test-retest reliability was at moderate level with intra-class correlation coefficients of 0.61-0.73 for the four subscales and 0.76 for the overall scale. Strong significant correlations between the MOS-SSS and the MSPSS (r = 0.77; p < 0.001) and the PSAS (r = - 0.76; p < 0.001) indicated good concurrent validity. Construct validity of the MOS-SSS was established since a final four-factor model fitted the data well with Comparative Fit Index (0.97), Tucker-Lewis Index (0.97), Standardized Root Mean Square Residual (0.03) and Root Mean Square Error of Approximation (0.068; 90% CI = 0.059-0.077). The MOS-SSS is a reliable and valid tool for measuring social support in Vietnamese MMT patients. Further studies among methadone patients at different stages of their treatment and among those from different areas of Vietnam are needed.

Knee complaints and their accompanying functional impairments are frequent problems encountered by healthcare practitioners worldwide. Plenty of functional scoring systems were developed and validated to give a relative estimation about the knee function. Despite the wide geographic distribution of Arabic language in the Middle East and North Africa, it is rare to find a validated knee function scale in Arabic. The present study is aimed to translate, validate, and culturally adjust the Knee Outcome Survey: Activities of Daily Living Scale (KOS-ADLS) into Arabic language for future use among Arabic-speaking patients. Permission for translation was obtained from the copyrights holder. Two different teams of high-level clinical and linguistic expertise conducted translation process blindly. Forward-backward translation technique was implemented to ensure preservation of the main conceptual content. Main study consisted of 280 subjects. Reliability was examined by test-retest pilot study. Visual Analogue Scale (VAS), Get Up and Go (GUG) Test, Ascending/Descending Stairs (A/D Stairs), and Subjective Assessment of Function (SAF) were conducted concurrently to show the validity of Arabic KOS-ADLS statistically in relation to these scales. Final translated version showed no significant discrepancies. Minor adaptive adjustment was required to fit Arabian cultural background. Internal consistency was favourable (Cronbach's alpha 0.90). Patients' scoring on Arabic KOS-ADLS appeared relatively consistent with their scoring on VAS, GUG, A/D Stairs, and SAF. A significant linear relationship was demonstrated between SAF and total KOS-ADLS scores on regression analysis (adj. R 2  = 0.548). Arabic KOS-ADLS, as its English counterpart, was found to be a simple, valid, and useful instrument for knee function evaluation. Arabic version of KOS-ADLS represents a promising candidate for unconditional use among Arabic-speaking patients with knee complaints.

To develop the Person-Environment Apathy Rating (PEAR) scale that measures environmental stimulation and apathy in persons with dementia and to evaluate its psychometrics. The PEAR scale consists of the PEAR-Environment subscale and PEAR-Apathy subscales. The items were developed via literature review, field testing, expert review, and pilot testing. The construct validity and reliability were examined through video observation. The parent study enrolled 185 institutionalized residents with dementia. For this study, 96 videos were selected from 24 participants. The PEAR-Environment subscale was validated using the Ambiance Scale and the Crowding Index. The PEAR-Apathy subscale was validated using the Neuropsychiatric Inventory (NPI)-Apathy, Passivity in Dementia Scale (PDS), and NPI-Depression. The PEAR-Environment subscale and PEAR-Apathy subscales each consists of six items rated on a 1-4 scale. For validity, the Crowding Index slightly, yet significantly, correlated with the PEAR-Environment subscale total score and three of the individual scores. Ambiance Scale scores, both engaging and soothing, did not correlate with the PEAR-Environment subscale. The PEAR-Apathy highly correlated with the PDS and NPI-Apathy and moderately correlated with the NPI-Depression, suggesting good convergent validity and moderate discriminant validity. For reliability, both environment and apathy subscales demonstrated excellent internal consistency. Although facial expression and eye contact showed moderate inter-rater reliability, all other items showed good to excellent inter-rater and intra-rater reliability. This study has successfully developed the PEAR scale and established its psychometrics based on the compatible scales available. The PEAR scale is the first scale that concurrently assesses apathy and environmental stimulation, and is recommended for use in persons with dementia.

The aim of the study was to evaluate the reliability and validity of the Italian SWAL-QOL (I-SWAL-QOL). The study consisted of five phases: item generation, reliability analysis, normative data generation, validity analysis, and responsiveness analysis. The item generation phase followed the five-step, cross-cultural, adaptation process of translation and back-translation. A group of 92 dysphagic patients was enrolled for the internal consistency analysis. Seventy-eight patients completed the I-SWAL-QOL twice, 2 weeks apart, for test-retest reliability analysis. A group of 200 asymptomatic subjects completed the I-SWAL-QOL for normative data generation. I-SWAL-QOL scores obtained by both the group of dysphagic subjects and asymptomatic ones were compared for validity analysis. I-SWAL-QOL scores were correlated with SF-36 scores in 67 patients with dysphagia for concurrent validity analysis. Finally, I-SWAL-QOL scores obtained in a group of 30 dysphagic patients before and after successful rehabilitation treatment were compared for responsiveness analysis. All the enrolled patients managed to complete the I-SWAL-QOL without needing any assistance, within 20 min. Internal consistency was acceptable for all I-SWAL-QOL subscales (α > 0.70). Test-retest reliability was also satisfactory for all subscales (ICC > 0.7). A significant difference between the dysphagic group and the control group was found in all I-SWAL-QOL subscales (p < 0.05). Mild to moderate correlations between I-SWAL-QOL and SF-36 subscales were observed. I-SWAL-QOL scores obtained in the pre-treatment condition were significantly lower than those obtained after swallowing rehabilitation. I-SWAL-QOL is reliable, valid, responsive to changes in QOL, and recommended for clinical practice and outcome research.

This study validates an existing spirituality measure--the intrinsic spirituality scale (ISS)--for use with Muslims in the United States. A confirmatory factor analysis was conducted with a diverse sample of self-identified Muslims (N = 281). Validity and reliability were assessed along with criterion and concurrent validity. The measurement model fit the data well, normed χ2 = 2.50, CFI = 0.99, RMSEA = 0.07, and SRMR = 0.02. All 6 items that comprise the ISS demonstrated satisfactory levels of validity (λ > .70) and reliability (R2 > .50). The Cronbach's alpha obtained with the present sample was .93. Appropriate correlations with theoretically linked constructs demonstrated criterion and concurrent validity. The results suggest the ISS is a valid measure of spirituality in clinical settings with the rapidly growing Muslim population. The ISS may, for instance, provide an efficient screening tool to identify Muslims that are particularly likely to benefit from spiritually accommodative treatments.

To develop the pediatric Automatic Phonological Analysis Tools (APAT) and to estimate inter and intrajudge reliability, content validity, and concurrent validity. The APAT were constructed using Excel spreadsheets with formulas. The tools were presented to an expert panel for content validation. The corpus used in the Portuguese standardized test Teste Fonético-Fonológico - ALPE produced by 24 children with phonological delay or phonological disorder was recorded, transcribed, and then inserted into the APAT. Reliability and validity of APAT were analyzed. The APAT present strong inter- and intrajudge reliability (>97%). The content validity was also analyzed (ICC = 0.71), and concurrent validity revealed strong correlations between computerized and manual (traditional) methods. The development of these tools contributes to fill existing gaps in clinical practice and research, since previously there were no valid and reliable tools/instruments for automatic phonological analysis, which allowed the analysis of different corpora.

Informal carers and health professionals who care for the patient during their last days of life can complete this assessment tool. The aim of the study is to carry out a cross-cultural adaptation and a psychometric analysis of the QODD for the Spanish population. The translation was performed using a double forward and backward method. An expert panel evaluated the content validity. The questionnaire was tested in a sample of 72 Spanish-speaking adult carers of deceased cancer patients. A psychometric analysis was performed to evaluate internal consistency, divergent criterion-related validity with the Mini-Suffering State Examination (MSSE) and concurrent criterion-related validity with the Palliative Outcome Scale (POS). Some items were deleted and modified to create the Spanish version of the QODD (QODD-ESP-26). The instrument was readable and acceptable. The content validity index was 0.96, suggesting that all items are relevant for the measure of the QoD. This questionnaire showed high internal consistency (Cronbach's α coefficient = 0.88). Divergent validity with MSSE (r = -0.64) and convergent validity with POS (r = -0.61) were also demonstrated. The QODD-ESP-26 is a valid and reliable instrument for the assessment of the QoD of deceased cancer patients that can be used in a clinical and research setting. Copyright © 2018 Elsevier Ltd.

ABILOCO-Kids is a measure of locomotion ability for children with cerebral palsy (CP) aged 6 to 15 years & is available in English & French. To validate the Gujarati version of ABILOCO-Kids questionnaire to be used in clinical research on Gujarati population. ABILOCO-Kids questionnaire was translated into Gujarati from English using forward-backward-forward method. To ensure face & content validity of Gujarati version using group consensus method, each item was examined by group of experts having mean experience of 24.62 years in field of paediatric and paediatric physiotherapy. Each item was analysed for content, meaning, wording, format, ease of administration & scoring. Each item was scored by expert group as either accepted, rejected or accepted with modification. Procedure was continued until 80% of consensus for all items. Concurrent validity was examined on 55 children with Cerebral Palsy (6-15 years) of all Gross Motor Functional Classification System (GMFCS) level & all clinical types by correlating score of ABILOCO-Kids with Gross Motor Functional Measure & GMFCS. In phase 1 of validation, 16 items were accepted as it is; 22 items accepted with modification & 3 items went for phase 2 validation. For concurrent validity, highly significant positive correlation was found between score of ABILOCO-Kids & total GMFM (r=0.713, p<0.005) & highly significant negative correlation with GMFCS (r= -0.778, p<0.005). Gujarati translated version of ABILOCO-Kids questionnaire has good face & content validity as well as concurrent validity which can be used to measure caregiver reported locomotion ability in children with CP.

Gamblers' cognitive distortions are thought to be an important mechanism involved in the development and maintenance of problem gambling. The Gambling Cognitions Inventory (GCI) evaluates two categories of distortions: beliefs that one is lucky (i.e., "Luck/Chance") and beliefs that one has special gambling-related skills (i.e., "Skill/Attitude"). Prior psychometric evaluations of the GCI demonstrated the utility of both subscales as measures of distortions and their concurrent relations to gambling problems among Canadian gamblers. However, these associations have not yet been studied in gamblers from other cultures nor have relationships between the GCI and indices of gambling behavior been investigated. In addition, the predictive validity of the GCI scales have not been evaluated in studies to date. The present study investigated the validity of the GCI as a measure of cognitive distortions in a sample of 49 Dutch gamblers by examining its concurrent and prospective relationships to both gambling problems (as measured through a standardized nine-item questionnaire assessing gambling-related problems) and behaviors (as measured through two variables: days spent gambling and time spent gambling in minutes) at baseline and over 1-month and 6-month intervals. The GCI subscales were internally consistent at all timepoints, and moderately to strongly inter-correlated at all timepoints. Each subscale correlated with an independent dimension of gambling both concurrently and prospectively: Luck/Chance was related to greater gambling problems and Skill/Attitude was related to greater gambling behavior . Thus, the two GCI subscales, while inter-correlated, appear to be related to different gambling outcomes, at least among Dutch gamblers. Moreover, the first evidence of the predictive validity of the GCI scales was demonstrated over a 1-month and 6-month interval. It is recommended that both types of cognitive distortions be considered in research and clinical practice to fully understand and address individual risk for excessive and problematic gambling.

Cross-sectional observational study to investigate psychometric properties of an adapted Thai version of the refined Scoliosis Research Society-22 (SRS-22) questionnaire. To evaluate the reliability and validity of the adapted Thai version of the refined SRS-22 questionnaire. The SRS-22 questionnaire is a valid instrument for assessing the health-related quality of life for patients with adolescent idiopathic scoliosis. Recently, the questionnaire has been translated and validated in many languages for non-English-speaking countries. Translation/retranslation of the English version of the SRS-22 was conducted, and the cross-cultural adaptation process was performed. The Thai version SRS-22 and previously validated Thai version Short-Form survey version 2.0 (SF-36V2) questionnaires were administered to 77 patients with adolescent idiopathic scoliosis who had surgical treatment. Fifty-eight patients (52 adolescent girls) had filled out the first set of questionnaires. Thirty patients of the first-time responders completed the second set of questionnaires. The mean age at the time of operation was 14.6 years and the mean age at the time of the final follow-up was 18.7 years. The mean preoperative scoliosis curve magnitude was 55.4° (range, 30°-95°) and postoperative curve magnitude was 20.1° (range, 0°-60°). Internal consistency was determined with Cronbach α coefficient. Intraclass correlation coefficient was used for test-retest reliability. Concurrent validity was evaluated by comparing SRS-22 domains with relevant domains in the SF-36V2 questionnaire, using the Pearson correlation coefficient. The mean overall Cronbach α coefficient of the adapted Thai version SRS-22 was 0.76. The 2 of corresponding domains (mental health = 0.80 and self-image = 0.83) had satisfactory internal consistency and the remaining domains (pain = 0.78; function/activity = 0.74; and satisfaction = 0.76) were good. The intraclass correlation coefficient for 5 domains was ranged from 0.79 to 0.90, which demonstrated the satisfactory test/retest reproducibility. The concurrent validity, determined by the Pearson correlation coefficient between SRS-22 and SF-36V2 domains, had a good correlation for 15 relevant comparisons (r = 0.50-0.75). The adapted Thai version of the SRS-22 questionnaire had validity and reliability, which can be used to assess the outcome of treatment among Thai-speaking patients with adolescent idiopathic scoliosis.

Objective: To evaluate the accuracy of computer adaptive tests (CATs) of daily routines for child- and parent-reported outcomes following pediatric spinal cord injury (SCI) and to evaluate the validity of the scales. Methods: One hundred ninety-six daily routine items were administered to 381 youths and 322 parents. Pearson correlations, intraclass correlation coefficients (ICC), and 95% confidence intervals (CI) were calculated to evaluate the accuracy of simulated 5-item, 10-item, and 15-item CATs against the full-item banks and to evaluate concurrent validity. Independent samples t tests and analysis of variance were used to evaluate the ability of the daily routine scales to discriminate between children with tetraplegia and paraplegia and among 5 motor groups. Results: ICC and 95% CI demonstrated that simulated 5-, 10-, and 15-item CATs accurately represented the full-item banks for both child- and parent-report scales. The daily routine scales demonstrated discriminative validity, except between 2 motor groups of children with paraplegia. Concurrent validity of the daily routine scales was demonstrated through significant relationships with the FIM scores. Conclusion: Child- and parent-reported outcomes of daily routines can be obtained using CATs with the same relative precision of a full-item bank. Five-item, 10-item, and 15-item CATs have discriminative and concurrent validity. PMID:23671380

To prevent complications from peripheral vascular access device (PVAD) therapy, the Infusion Nurses Society (INS) developed 2 scales to measure the extent and severity of phlebitis and infiltration in PVADs. This study evaluated the psychometric properties of these scales to validate them with respect to their interrater reliability, concurrent validity, feasibility, and acceptability. A total of 182 patients at 2 sites were enrolled, and 416 observations of PVAD sites were made. Two nurses independently rated each PVAD site for the presence or absence of phlebitis and/or infiltration by using the INS scales. The interrater reliability was calculated, as was the agreement of the observed versus charted incidence of phlebitis and infiltration (concurrent validity) and the ease of use of the scales (feasibility, acceptability). Interrater reliability for both the Phlebitis and Infiltration scales and concurrent validity were found to be statistically significant (P < .05). The study nurses reported the scales to be easy to use, taking an average of 1.3 minutes to complete both. The importance of valid measures for use in research cannot be underestimated. The INS Phlebitis and Infiltration scales have been shown to be easy to use, valid, and reliable scales.

Development and validation of a reading-related assessment battery in Malay for the purpose of dyslexia assessment.

Malay is an alphabetic language with transparent orthography. A Malay reading-related assessment battery which was conceptualised based on the International Dyslexia Association definition of dyslexia was developed and validated for the purpose of dyslexia assessment. The battery consisted of ten tests: Letter Naming, Word Reading, Non-word Reading, Spelling, Passage Reading, Reading Comprehension, Listening Comprehension, Elision, Rapid Letter Naming and Digit Span. Content validity was established by expert judgment. Concurrent validity was obtained using the schools' language tests as criterion. Evidence of predictive and construct validity was obtained through regression analyses and factor analyses. Phonological awareness was the most significant predictor of word-level literacy skills in Malay, with rapid naming making independent secondary contributions. Decoding and listening comprehension made separate contributions to reading comprehension, with decoding as the more prominent predictor. Factor analysis revealed four factors: phonological decoding, phonological naming, comprehension and verbal short-term memory. In conclusion, despite differences in orthography, there are striking similarities in the theoretical constructs of reading-related tasks in Malay and in English.

Affects and Affect Consciousness

Affect consciousness (AC) was operationalized as degrees of awareness, tolerance, nonverbal expression, and conceptual expression of nine specific affects. A semistructured interview (ACI) and separate scales were developed to assess these aspects of affect integration. Their psychometric properties were preliminarily explored by having 20 former psychiatric outpatients complete the interview. Concurrent validity was assessed by using DSM-III-R Axis I and II diagnoses, the Health-Sickness Rating Scale, SCL-90-R, and several indexes from the Minnesota Multiphasic Personality Inventory. Satisfactory interrater reliability and high levels of internal consistency supported the construct validity of the measure. Results suggest the most meaningful use of this instrument is in measuring specific affect and overall AC. Clinically, the ACI has provided highly specific and relevant qualitative data for use in planning psychotherapeutic interventions. PMID:22700292

Older adults prefer to remain in their own homes for as long as possible. The purpose of this article is to describe the development and preliminary validation of Making and Executing Decisions for Safe and Independent Living (MED-SAIL), a brief screening tool for capacity to live safely and independently in the community. Prospective preliminary validation study. Outpatient geriatrics clinic located in a community-based hospital. Forty-nine community-dwelling older adults referred to the clinic for a comprehensive capacity assessment. We examined internal consistency, criterion-based validity, concurrent validity, and accuracy of classification for MED-SAIL. The items included in MED-SAIL demonstrated internal consistency (5 items; α = 0.85). MED-SAIL was significantly correlated with the Independent Living Scales (r = 0.573, p ≤0.001) and instrumental activities of daily living (r = 0.440, p ≤0.01). The Mann-Whitney U test revealed significant differences between the no capacity and partial/full capacity classifications on MED-SAIL (U(48) = 60.5, Z = -0.38, p <0.0001). The area under the curve was 0.864 (95% confidence interval: 0.84-0.99). This study demonstrated the validity of MED-SAIL as a brief screening tool to identify older adults with impaired capacity for remaining safe and independent in their current living environment. MED-SAIL is useful tool for health and social service providers in the community for the purpose of referral for definitive capacity evaluation. Published by Elsevier Inc.

Treadmill gait analysis was more advantageous than over-ground walking because it allowed continuous measurements of the gait parameters. The purpose of this study was to investigate the concurrent validity and the test-retest reliability of the OPTOGait photoelectric cell system against the treadmill-based gait analysis system by assessing spatio-temporal gait parameters. Twenty-six stroke patients and 18 healthy adults were asked to walk on the treadmill at their preferred speed. The concurrent validity was assessed by comparing data obtained from the 2 systems, and the test-retest reliability was determined by comparing data obtained from the 1st and the 2nd session of the OPTOGait system. The concurrent validity, identified by the intra-class correlation coefficients (ICC [2, 1]), coefficients of variation (CVME), and 95% limits of agreement (LOA) for the spatial-temporal gait parameters, were excellent but the temporal parameters expressed as a percentage of the gait cycle were poor. The test-retest reliability of the OPTOGait System, identified by ICC (3, 1), CVME, 95% LOA, standard error of measurement (SEM), and minimum detectable change (MDC95%) for the spatio-temporal gait parameters, was high. These findings indicated that the treadmill-based OPTOGait System had strong concurrent validity and test-retest reliability. This portable system could be useful for clinical assessments.

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.

Purpose/hypothesis: This study was designed to investigate the test-retest reliability, concurrent validity, and the standard error of measurement (SEm) of a pulse rate assessment application (Azumio®'s Instant Heart Rate) on both Android® and iOS® (iphone operating system) smartphones as compared to a FT7 Polar® Heart Rate monitor. Number of subjects: 111. Resting (sitting) pulse rate was assessed twice and then the participants were asked to complete a 1-min standing step test and then immediately re-assessed. The smartphone assessors were blinded to their measurements. Test-retest reliability (intraclass correlation coefficient [ICC 2,1] and 95% confidence interval) for the three tools at rest (time 1/time 2): iOS® (0.76 [0.67-0.83]); Polar® (0.84 [0.78-0.89]); and Android® (0.82 [0.75-0.88]). Concurrent validity at rest time 2 (ICC 2,1) with the Polar® device: IOS® (0.92 [0.88-0.94]) and Android® (0.95 [0.92-0.96]). Concurrent validity post-exercise (time 3) (ICC) with the Polar® device: iOS® (0.90 [0.86-0.93]) and Android® (0.94 [0.91-0.96]). The SEm values for the three devices at rest: iOS® (5.77 beats per minute [BPM]), Polar® (4.56 BPM) and Android® (4.96 BPM). The Android®, iOS®, and Polar® devices showed acceptable test-retest reliability at rest and post-exercise. Both the smartphone platforms demonstrated concurrent validity with the Polar® at rest and post-exercise. The Azumio® Instant Heart Rate application when used by either platform appears to be a reliable and valid tool to assess pulse rate in healthy individuals.

Brief report: Assessing dispositional optimism in adolescence--factor structure and concurrent validity of the Life Orientation Test--Revised.

PubMed

Monzani, Dario; Steca, Patrizia; Greco, Andrea

2014-02-01

Dispositional optimism is an individual difference promoting psychosocial adjustment and well-being during adolescence. Dispositional optimism was originally defined as a one-dimensional construct; however, empirical evidence suggests two correlated factors in the Life Orientation Test - Revised (LOT-R). The main aim of the study was to evaluate the dimensionality of the LOT-R. This study is the first attempt to identify the best factor structure, comparing congeneric, two correlated-factor, and two orthogonal-factor models in a sample of adolescents. Concurrent validity was also assessed. The results demonstrated the superior fit of the two orthogonal-factor model thus reconciling the one-dimensional definition of dispositional optimism with the bi-dimensionality of the LOT-R. Moreover, the results of correlational analyses proved the concurrent validity of this self-report measure: optimism is moderately related to indices of psychosocial adjustment and well-being. Thus, the LOT-R is a useful, valid, and reliable self-report measure to properly assess optimism in adolescence. Copyright © 2013 The Foundation for Professionals in Services for Adolescents.

Some studies have reported that people with intellectual disability may have reduced balance ability compared with the population in general. However, none of these studies involved adolescents, and the reliability and validity of balance tests in this population are not known. The purpose of this study was to examine the reliability of six different balance tests and to investigate their concurrent validity. Test-retest reliability assessment. All subjects were recruited from a special school for people with intellectual disability in Bollnäs, Sweden. Eighty-nine adolescents (35 females and 54 males) with mild to moderate intellectual disability with a mean age of 18 years (range 16 to 20 years). All subjects followed the same test protocol on two occasions within an 11-day period. Balance test performances. Intraclass correlation coefficients greater than 0.80 were achieved for four of the balance tests: Extended Timed Up and Go Test, Modified Functional Reach Test, One-leg Stance Test and Force Platform Test. The smallest real differences ranged from 12% to 40%; less than 20% is considered to be low. Concurrent validity among these balance tests varied between no and low correlation. The results indicate that these tests could be used to evaluate changes in balance ability over time in people with mild to moderate intellectual disability. The low concurrent validity illustrates the importance of knowing more about the influence of various sensory subsystems that are significant for balance among adolescents with intellectual disability.

Mazure, C; Nelson, J C; Price, L H

1986-05-01

In two consecutive studies, we examined the interrater reliability and then the concurrent validity of interview ratings for individual symptoms of major depressive illness. The concurrent validity of symptoms was determined by assessing the degree to which symptoms observed or reported during an interview were observed in daily behavior. Results indicated that most signs and symptoms of major depression and melancholia can be reliably rated by clinicians during a semistructured interview. Ratings of observable symptoms (signs) assessed during the interview were valid indicators of dysfunction observed in daily behavior. Several but not all ratings based on patient report of symptoms were at variance with observation. These discordant patient-reported symptoms may have value as subjective reports but were not accurate descriptions of observed dysfunction.

The Spine Functional Index (SFI) is a recently published, robust and clinimetrically valid patient reported outcome measure. The purpose of this study was the adaptation and validation of a Spanish-version (SFI-Sp) with cultural and linguistic equivalence. A two stage observational study was conducted. The SFI was cross-culturally adapted to Spanish through double forward and backward translation then validated for its psychometric characteristics. Participants (n = 226) with various spine conditions of >12 weeks duration completed the SFI-Sp and a region specific measure: for the back, the Roland Morris Questionnaire (RMQ) and Backache Index (BADIX); for the neck, the Neck Disability Index (NDI); for general health the EQ-5D and SF-12. The full sample was employed to determine internal consistency, concurrent criterion validity by region and health, construct validity and factor structure. A subgroup (n = 51) was used to determine reliability at seven days. The SFI-Sp demonstrated high internal consistency (α = 0.85) and reliability (r = 0.96). The factor structure was one-dimensional and supported construct validity. Criterion specific validity for function was high with the RMQ (r = 0.79), moderate with the BADIX (r = 0.59) and low with the NDI (r = 0.46). For general health it was low with the EQ-5D and inversely correlated (r = -0.42) and fair with the Physical and Mental Components of the SF-12 and inversely correlated (r = -0.56 and r = -0.48), respectively. The study limitations included the lack of longitudinal data regarding other psychometric properties, specifically responsiveness. The SFI-Sp was demonstrated as a valid and reliable spine-regional outcome measure. The psychometric properties were comparable to and supported those of the English-version, however further longitudinal investigations are required.

The purpose of this study was to test the reliability, validity, and factor structure of a Chinese version of the Psychotic Symptom Rating Scale (PSYRATS) in 198 and 202 adult patients with recent-onset and chronic psychosis, respectively. The PSYRATS has been translated into different language versions and has been validated for clinical and research use mainly in chronic psychotic patients but not in recent-onset psychosis patients or in Chinese populations. The psychometric analysis of the translated Chinese version included assessment of its content validity, semantic equivalence, interrater and test-retest reliability, reproducibility, sensitivity to changes in psychotic symptoms, internal consistency, concurrent validity (compared to a valid psychotic symptom scale), and factor structure. The Chinese version demonstrated very satisfactory content validity as rated by an expert panel, good semantic equivalence with the original version, and high interrater and test-retest (at 2-week interval) reliability. It also indicated very good reproducibility of and sensitivity to changes in psychotic symptoms in line with the symptom severity measured with the Positive and Negative Syndrome Scale (PANSS). The scale consisted of four factors for the hallucination subscale and two factors for the delusion subscale, explaining about 80% of the total variance of the construct, indicating satisfactory correlations between the hallucination and delusion factors themselves, between items, factors, subscales, and overall scale, and between factors and relevant item and subscale scores of the PANSS. The Chinese version of the PSYRATS is a reliable and valid instrument to measure symptom severity in Chinese psychotic patients complementary to other existing measures mainly in English language.

There is no agreement about the measure to quantify the intellectual/developmental level in children with the dual disability of intellectual disability and autism. Therefore, we studied the psychometric properties and utility of Psycho-Educational Profile-Revised (PEP-R) as a developmental test in this population. We identified 116 children with dual disability from the day care and inpatient database of a specialised Autism Clinic. Scale and domain level scores of PEP-R were collected and analyzed. We examined the internal consistency, domain-total correlation of PEP-R and concurrent validity of PEP-R against Gesell's Developmental Schedule, inter-rater and test-retest reliability and utility of PEP-R among children with dual disability in different ages, functional level and severity of autism. Besides the adequate face and content validity, PEP-R demonstrates a good internal consistency (Cronbach's α ranging from 0.91 to 0.93) and domain-total correlation (ranging from 0.75 to 0.90). The inter-rater reliability (intraclass correlation coefficient, ICC = 0.96) and test-retest reliability (ICC = 0.87) for PEP-R is good. There is moderate-to-high concurrent validity with GDS (r ranging from 0.61 to 0.82; all Ps = 0.001). The utility of PEP-R as a developmental measure was good with infants, toddlers, pre-school and primary school children. The ability of PEP-R to measure the developmental age was good, irrespective of the severity of autism but was better with high-functioning children. The PEP-R as an intellectual/developmental test has strong psychometric properties in children with dual disability. It could be used in children with different age groups and severity of autism. PEP-R should be used with caution as a developmental test in children with dual disability who are low functioning.

Previous research has demonstrated a link between early experiences of warmth, safeness, and soothing, and positive feelings, health, and well-being outcomes. Although the impact of positive parent-related early relationships and its posterior recall is well documented, research on the recall of warmth and safeness experiences within early peer relationships remains scarce. In fact, it is considered that the protective role of early positive peer relationships deserves intensive research; however, a specific measure that assesses this construct is still to be created. This study describes the development and validation of a new measure designed to assess the recall of early experiences of warmth, safeness, and affection in relation to peers (EMWSS-peers). Distinct samples, comprising individuals of both genders aged between 18 and 68 years old, were used to test the EMWSS-peers factorial structure through principal axis factoring (PAF) and confirmatory factor analysis (CFA), and to examine its psychometric properties. Principal axis factoring's results indicated that the 12-item scale presents a one-factor structure explaining a total of 71.50% of the variance. The CFA confirmed the plausibility of this structure. The EMWSS-peers also presented excellent internal consistency and construct, concurrent, and divergent validities. The EMWSS-peers seems to be a new avenue for the study of memories of early experiences with friends and colleagues and may entail a relevant contribution to clinical and research fields, particularly for upcoming investigations on the relationship of peer-related affiliative memories with well-being and mental health. The EMWSS-peers is a specific measure to assess the recall of warmth and safeness in early peer relationships. The EMWSS-peers is a brief, robust, and reliable self-report instrument. The EMWSS-peers presented excellent internal consistency and construct, concurrent, and divergent validities. The EMWSS-peers may open a new avenue for the study of memories of early peer-related experiences, with potential clinical and research implications. © 2017 The British Psychological Society.

We examined concurrent validity of scores for two infant motor screening tools, the Harris Infant Neuromotor Test (HINT) and the Alberta Infant Motor Scale, in 121 Canadian infants. Relationships between the two tests for the overall sample were as follows: r = -.83 at 4 to 6.5 months (n = 121; p < .01) and r = -.85 at 10 to 12.5 months (n = 109; p < .01), suggesting that the HINT, the newer of the two measures, is valid in determining motor delays. Each test has advantages and disadvantages, and practitioners should determine which one best meets their infant assessment needs.

Concurrent validation procedures were employed, using a sample of African American precollege students, to determine the extent to which scale scores obtained from the first edition of the Learning and Study Strategies Inventory (LASSI) were appropriate for diagnostic purposes. Data analysis revealed that 2 of the 10 LASSI scales (i.e., Anxiety and Test Strategies) significantly correlated with a measure of academic ability. These results suggested that scores obtained from these LASSI scales may provide valid assessments of African American precollege students’ academic aptitude. Implications for teachers, school counselors, and developmental studies professionals were discussed.

Elderly social isolation could be prevented by facilitating communication or mutual helping at the neighborhood level. The helping of elderly neighbors by local volunteers may relate to their community commitment (CC), but ways to measure CC have not been identified. The aim of the present study was to develop a Community Commitment Scale (CCS) to measure psychological sense of belonging and socializing in the community among local volunteers, for research in prevention of elderly social isolation. We also tested the CCS in a general population of the elderly. A pilot test of 266 Japanese urban residents was conducted to examine face validity for 24 identified items, of which 12 items were selected for the CCS, based on a 4-point Likert-type scale. The CCS was developed via self-report questionnaires to 859 local volunteers in two suburban cities and to 3484 randomly sampled general residents aged 55 years or older living in one of the cities. To assess concurrent validity, data were collected using the Brief Sense of Community Scale (Peterson; 2008) and two types of single questions on self-efficacy for helping elderly neighbors. Item analysis and factor analysis identified 8 items, which were classified between two datasets under the domains of "belonging" and "socializing" in the local volunteers and the general residents. Cronbach's alpha (which conveyed the internal consistency of the CCS) was 0.75 in local volunteers and 0.78 in general residents. The correlation coefficients between the scores of the CCS and BSCS were 0.54 for local volunteers and 0.62 for general residents. ANOVA comparing the CCS between the confidence levels of the two types of single question of self-efficacy on helping elderly neighbors showed a strong relationship in the volunteers and residents. These results demonstrate acceptable internal consistency and concurrent validity for the CCS, with the two dimensions "belonging" and "socializing", among the local volunteers and general residents in urban Japanese areas. Community commitment measured by the CCS was related to the degree of confidence for self-efficacy in helping elderly neighbors to prevent elderly social isolation.

The participants in the NIMH-MATRICS Consensus Development Conference on Negative Symptoms recommended that an instrument be developed that measured blunted affect, alogia, asociality, anhedonia, and avolition. The Brief Negative Symptom Scale (BNSS) is a 13-item instrument designed for clinical trials and other studies that measures these 5 domains. The interrater, test-retest, and internal consistency of the instrument were strong, with respective intraclass correlation coefficients of 0.93 for the BNSS total score and values of 0.89-0.95 for individual subscales. Comparisons with positive symptoms and other negative symptom instruments supported the discriminant and concurrent validity of the instrument.

The Observation Scale for Aggressive Behavior (OSAB) has been developed to evaluate inpatient treatment programs designed to reduce aggressive behavior in Dutch forensic psychiatric patients with an antisocial personality disorder, who are "placed at the disposal of the government". The scale should have the sensitivity to measure changes in the possible determinants of aggressive behavior, such as limited control of displayed negative emotions (irritation, anger or rage) and a general deficiency of social skills. In developing the OSAB 40 items were selected from a pool of 82 and distributed among the following a priori scales: Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent (to aggressive behavior), Sanction (for aggressive behavior) and Social behavior. The internal consistency of these subscales was good, the inter-rater reliability was moderate to good, and the test-retest reliability over a two to three week period was moderate to good. The correlation between the subscales Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent, Sanction was substantial and significant, but the anticipated negative correlation between these subscales and the Social behavior subscale could not be shown. Relationships between the corresponding subscales of the OSAB and the FIOS, used to calculate concurrent validity, yielded relatively high correlations. The validity of the various OSAB subscales could be further supported by significant correlations with the PCL-R and by significant but weak correlations with corresponding subscales of the self-report questionnaires. The Observation Scale for Aggressive Behavior (OSAB) seems to measure aggressive behavior in Dutch forensic psychiatric inpatients with an antisocial personality disorder reliably and validly. Contrary to expectations, a negative relationship was not found between aggressive and social behavior in either the OSAB or FIOS, which were used for calculating concurrent validity.

Introduction No tool currently used by primary health care providers to assess physical activity has been evaluated for its ability to determine whether or not patients achieve recommended levels of activity. The purpose of this study was to assess concurrent validity of physical activity self-reported to the brief (<30 sec) Physical Activity “Vital Sign” questionnaire (PAVS) compared with responses to the lengthier (3–5 min), validated Modifiable Activity Questionnaire (MAQ). Methods Agreement between activity reported to the PAVS and MAQ by primary care patients at 2 clinics in 2014 was assessed by using percentages and κ coefficients. Agreement consisted of meeting or not meeting the 2008 Aerobic Physical Activity Guidelines for Americans (PA Guidelines) of the US Department of Health and Human Services. We compared self-reported usual minutes per week of moderate-to-vigorous physical activity among patients at a primary care clinic in 2014 who reported to PAVS and to MAQ by using Pearson correlation and Bland–Altman plots of agreement. Results Among 269 consenting patients who reported physical activity, PAVS results agreed with those of MAQ 89.6% of the time and demonstrated good agreement in identifying patients who did not meet PA Guidelines recommendations (κ = 0.55, ρ = 0.57; P < .001). Usual minutes per week of moderate-to-vigorous physical activity reported to PAVS had a high positive correlation with the same reported to MAQ (r = 0.71; P < .001). Conclusion PAVS may be a valid tool for identifying primary care patients who need counseling about physical activity. PAVS should be assessed further for agreement with repeated objective measures of physical activity in the patient population. PMID:26851335

Clinically feasible methods of assessing postural control such as timed standing balance and functional reach tests provide important information, however, they cannot accurately quantify specific postural control mechanisms. The Microsoft Kinect™ system provides real-time anatomical landmark position data in three dimensions (3D), and given that it is inexpensive, portable and simple to setup it may bridge this gap. This study assessed the concurrent validity of the Microsoft Kinect™ against a benchmark reference, a multiple-camera 3D motion analysis system, in 20 healthy subjects during three postural control tests: (i) forward reach, (ii) lateral reach, and (iii) single-leg eyes-closed standing balance. For the reach tests, the outcome measures consisted of distance reached and trunk flexion angle in the sagittal (forward reach) and coronal (lateral reach) planes. For the standing balance test the range and deviation of movement in the anatomical landmark positions for the sternum, pelvis, knee and ankle and the lateral and anterior trunk flexion angle were assessed. The Microsoft Kinect™ and 3D motion analysis systems had comparable inter-trial reliability (ICC difference=0.06±0.05; range, 0.00-0.16) and excellent concurrent validity, with Pearson's r-values >0.90 for the majority of measurements (r=0.96±0.04; range, 0.84-0.99). However, ordinary least products analyses demonstrated proportional biases for some outcome measures associated with the pelvis and sternum. These findings suggest that the Microsoft Kinect™ can validly assess kinematic strategies of postural control. Given the potential benefits it could therefore become a useful tool for assessing postural control in the clinical setting. Copyright © 2012 Elsevier B.V. All rights reserved.

Participation in home, school, and community activities is an important indicator of child health and well-being. Evaluating environmental influences on children's participation can inform efforts to develop sustainable built environments, but few validated measures exist. To examine the concurrent validity and utility of the Participation and Environment Measure for Children and Youth (PEM-CY) for Health Impact Assessment in non-urban sustainable development projects affecting children with disabilities. Eighty-nine parents of children and youth with disabilities who identified as residing in a small town or rural community were sampled. Sixty-six caregivers completed the PEM-CY online, and 23 caregivers completed the PEM-CY and CHIEF-CP paper forms. Spearman correlational analyses were conducted to establish the concurrent validity of the PEM-CY environment sections against the CHIEF-CP. Group comparisons by child's age, number of functional limitations, and annual household income were used to examine differences in summary and item-level responses on the PEM-CY community section. Moderate to strong associations were found between CHIEF-CP Total Product and Magnitude Scores and all PEM-CY Environment Summary Scores. CHIEF-CP Physical/Structural and Policies Subscale Scores were most consistently associated with PEM-CY Environment Summary Scores. Group differences by household income were found for participation frequency and number of supports, including perceived availability and adequacy of money and information about programs and services, even when controlling child's age and number of functional limitations. Study results lend support to the use of the PEM-CY in HIA to reliably assess for environmental impact on children's participation. Implications for using the PEM-CY to inform decision-making in non-urban sustainable development projects affecting families of children and youth with disabilities are discussed.

Context The 15-item University of Washington Quality of Life questionnaire – Radiation Therapy Oncology Group (RTOG) modification (UW-QOL-RTOG modification) has been used in several trials of head and neck cancer conducted by NRG Oncology such as RTOG 9709, RTOG 9901, RTOG 0244, and RTOG 0537. Objectives This study is an exploratory factor analysis (EFA) to establish validity and reliability of the instrument subscales. Methods EFA on the UW-QOL - RTOG modification was conducted using baseline data from NRG Oncology's RTOG 0537, a trial of acupuncture-like transcutaneous electrical nerve stimulation in treating radiation-induced xerostomia. Cronbach's α coefficient was calculated to measure reliability; correlation with the University of Michigan Xerostomia Related Quality of Life Scale (XeQOLS) was used to evaluate concurrent validity; and correlations between consecutive time points were used to assess test-retest reliability. Results The 15-item EFA of the modified tool resulted in 11 items split into 4 factors: mucus, eating, pain, and activities. Cronbach's α ranged from 0.71 to 0.93 for the factors and total score, consisting of all 11 items. There were strong correlations (ρ≥0.60) between consecutive time points and between total score and the XeQOLS total score (ρ>0.65). Conclusion The UW-QOL-RTOG modification is a valid tool that can be used to assess symptom burden of head and neck cancer patients receiving radiation therapy or those who have recently completed radiation. The modified tool has acceptable reliability, concurrent validity, and test-retest reliability in this patient population, as well as the advantage of having being shortened from 15 to 11 items.

Background On February 27, 2010 (F-27), an earthquake and tsunami occurred having a significant impact on the mental health of the Chilean population, leading to an increase in cases of post-traumatic stress disorder (PTSD). Objectives Within this context, validated for the first time in Chile was the Davidson Trauma Scale (DTS) using three samples (each one consisting of 200 participants), two of them random from the Chilean population. Results Reliability analyses (i.e., α=0.933), concurrent validity (63% of the items are significantly correlated with the criteria variable “degree of damage to home”) and construct validity (i.e., CMIN = 3.754, RMSEA = 0.118, NFI = 0.808, CFI = 0.850 and PNFI = 0.689) indicate validity between regular and good for DTS. However, a new short version of the scale (DTS-SF) created using the items with heavier factor weights, presented better fits (CMIN = 2.170, RMSEA = 0.077, NFI = 0.935, CFI = 0.963, PNFI = 0.697). Discussion Finally, the usefulness of DTS and DTS-SF is discussed, the latter being briefer, valid and having better psychometric characteristics. PMID:23983920

Background ABILOCO-Kids is a measure of locomotion ability for children with cerebral palsy (CP) aged 6 to 15 years & is available in English & French. Aim To validate the Gujarati version of ABILOCO-Kids questionnaire to be used in clinical research on Gujarati population. Materials and Methods ABILOCO-Kids questionnaire was translated into Gujarati from English using forward-backward-forward method. To ensure face & content validity of Gujarati version using group consensus method, each item was examined by group of experts having mean experience of 24.62 years in field of paediatric and paediatric physiotherapy. Each item was analysed for content, meaning, wording, format, ease of administration & scoring. Each item was scored by expert group as either accepted, rejected or accepted with modification. Procedure was continued until 80% of consensus for all items. Concurrent validity was examined on 55 children with Cerebral Palsy (6-15 years) of all Gross Motor Functional Classification System (GMFCS) level & all clinical types by correlating score of ABILOCO-Kids with Gross Motor Functional Measure & GMFCS. Result In phase 1 of validation, 16 items were accepted as it is; 22 items accepted with modification & 3 items went for phase 2 validation. For concurrent validity, highly significant positive correlation was found between score of ABILOCO-Kids & total GMFM (r=0.713, p<0.005) & highly significant negative correlation with GMFCS (r= -0.778, p<0.005). Conclusion Gujarati translated version of ABILOCO-Kids questionnaire has good face & content validity as well as concurrent validity which can be used to measure caregiver reported locomotion ability in children with CP.

The aim of this study is to present the construct and concurrent validity of a motion-tracking method of laparoscopic instruments based on an optical pose tracker and determine its feasibility as an objective assessment tool of psychomotor skills during laparoscopic suturing. A group of novice ([Formula: see text] laparoscopic procedures), intermediate (11-100 laparoscopic procedures) and experienced ([Formula: see text] laparoscopic procedures) surgeons performed three intracorporeal sutures on an ex vivo porcine stomach. Motion analysis metrics were recorded using the proposed tracking method, which employs an optical pose tracker to determine the laparoscopic instruments' position. Construct validation was measured for all 10 metrics across the three groups and between pairs of groups. Concurrent validation was measured against a previously validated suturing checklist. Checklists were completed by two independent surgeons over blinded video recordings of the task. Eighteen novices, 15 intermediates and 11 experienced surgeons took part in this study. Execution time and path length travelled by the laparoscopic dissector presented construct validity. Experienced surgeons required significantly less time ([Formula: see text]), travelled less distance using both laparoscopic instruments ([Formula: see text]) and made more efficient use of the work space ([Formula: see text]) compared with novice and intermediate surgeons. Concurrent validation showed strong correlation between both the execution time and path length and the checklist score ([Formula: see text] and [Formula: see text], [Formula: see text]). The suturing performance was successfully assessed by the motion analysis method. Construct and concurrent validity of the motion-based assessment method has been demonstrated for the execution time and path length metrics. This study demonstrates the efficacy of the presented method for objective evaluation of psychomotor skills in laparoscopic suturing. However, this method does not take into account the quality of the suture. Thus, future works will focus on developing new methods combining motion analysis and qualitative outcome evaluation to provide a complete performance assessment to trainees.

In the United States, heterosexual transmission of HIV infection is dramatically higher among Blacks than among Whites. Overlapping (concurrent) sexual partnerships promote HIV transmission. The authors describe their process for developing a radio campaign (Escape the Web) to raise awareness among 18-34-year-old Black adults of the effect of concurrency on HIV transmission in the rural South. Radio is a powerful channel for the delivery of narrative-style health messages. Through six focus groups (n = 51) and 42 intercept interviews, the authors explored attitudes toward concurrency and solicited feedback on sample messages. Men were advised to (a) end concurrent partnerships and not to begin new ones; (b) use condoms consistently with all partners; and (c) tell others about the risks of concurrency and benefits of ending concurrent partnerships. The narrative portrayed risky behaviors that trigger initiation of casual partnerships. Women were advised to (a) end partnerships in which they are not their partner's only partner; (b) use condoms consistently with all partners; and (c) tell others about the risks of concurrency and benefits of ending concurrent partnerships. Messages for all advised better modeling for children.

Activity is key to maintaining physical and mental health and well-being. However, as dementia affects the ability to engage in activity, care-givers can find it difficult to provide appropriate activities. The Pool Activity Level (PAL) Checklist guides the selection of appropriate, personally meaningful activities. The aim of this study was to assess the reliability and validity of the PAL Checklist when used with older people with dementia. A postal questionnaire sent to activity providers assessed content validity. Validity and reliability were measured in a sample of 60 older people with dementia. The questionnaire response rate was 83% (102/122). Most respondents felt no important items were missing. Seven of the nine activities were ranked as 'very important' or 'essential' by at least 77% of the sample, indicating very good content validity. Correlation with measures of cognition, severity of dementia and activity performance demonstrated strong concurrent validity. Inter-item correlation indicated strong construct validity. Cronbach's alpha coefficient measured internal consistency as excellent (0.95). All items achieved acceptable test-retest reliability, and the majority demonstrated acceptable inter-rater reliability. We conclude that the PAL Checklist demonstrates adequate validity and reliability when used with older people with dementia and appears a useful tool for a variety of care settings.

The Short-Form Health Survey (SF-36) is a valid quality of life tool often employed to determine the impact of medical intervention and the outcome of health care services. However, the SF-36 is culturally sensitive which necessitates its adaptation and translation into different languages. This study was conducted to cross-culturally adapt the SF-36 into Yoruba language and determine its reliability and validity. Based on the International Quality of Life Assessment project guidelines, a sequence of translation, test of item-scale correlation, and validation was implemented for the translation of the Yoruba version of the SF-36. Following pilot testing, the English and the Yoruba versions of the SF-36 were administered to a random sample of 1087 apparently healthy individuals to test validity and 249 respondents completed the Yoruba SF-36 again after two weeks to test reliability. Data was analyzed using Pearson's product moment correlation analysis, independent t-test, one-way analysis of variance, multi trait scaling analysis and Intra-Class Correlation (ICC) at p < 0.05. The concurrent validity scores for scales and domains ranges between 0.749 and 0.902 with the highest and lowest scores in the General Health (0.902) and Bodily Pain (0.749) scale. Scale-level descriptive result showed that all scale and domain scores had negative skewness ranging from -2.08 to -0.98. The mean scores for each scales ranges between 83.2 and 88.8. The domain scores for Physical Health Component and Mental Health Component were 85.6 ± 13.7 and 85.9 ± 15.4 respectively. The convergent validity was satisfactory, ranging from 0.421 to 0.907. Discriminant validity was also satisfactory except for item '1'. The ICC for the test-retest reliability of the Yoruba SF-36 ranges between 0.636 and 0.843 for scales; and 0.783 and 0.851 for domains. The data quality, concurrent and discriminant validity, reliability and internal consistency of the Yoruba version of the SF-36 are adequate and it is recommended for measuring health-related quality of life among Yoruba population.

This was a prospective clinical validation study. To evaluate the reliability and validity of the adapted simplified Chinese version of Swiss Spinal Stenosis (SC-SSS) Questionnaire. The SSS Questionnaire is a reliable and valid instrument to assess the perception of function and pain for patients with degenerative lumbar spinal stenosis. However, there is no culturally adapted SSS Questionnaire for use in mainland China. This was a prospective clinical validation study. The adaption was conducted according to International Quality of Life Assessment Project guidelines. To examine the psychometric properties of the adapted SC-SSS Questionnaire, a sample of 105 patients with lumbar spinal stenosis were included. Thirty-two patients were randomly selected to evaluate the test-retest reliability. Reliability assessment of the SC-SSS Questionnaire was determined by calculating Cronbach α and intraclass coefficient values. Concurrent validity was assessed by correlating SC-SSS Questionnaire scores with relevant domains of the 36-Item Short Form Health Survey. Cronbach α of the symptom severity scale, physical function scale, patients, and satisfaction scale of SC-SSS Questionnaire are 0.89, 0.86, 0.91, respectively, which revealed very good internal consistency. The test-retest reproducibility was found to be excellent with the intraclass correlation coefficient of 0.93, 0.91, and 0.95. In terms of concurrent validity, SC-SSS Questionnaire had good correlation with physical functioning and bodily pain of 36-Item Short Form Health Survey (r = 0.663, 0.653) and low correlation with mental health (r = 0.289). The physical function scale had good correlation with physical functioning of 36-Item Short Form Health Survey (r = 0.637), whereas the rest had moderate correlation. The satisfaction scale score was highly correlated with the change in the symptom severity (r = 0.71) and physical function (r = 0.68) scale score. The SC-SSS Questionnaire showed satisfactory reliability and validity in the evaluation of functionality in patients with lumbar spinal stenosis who are experiencing neurogenic claudication. It is simple and easy to use and can be recommended in clinical and research practice in mainland China. 3.

The aim of the present study was to explore the concurrent validity, inter-rater agreement and diagnostic sensitivity of a French adaptation of the Coma Recovery Scale-Revised (CRS-R) as compared to other coma scales such as the Glasgow Coma Scale (GCS), the Full Outline of UnResponsiveness scale (FOUR) and the Wessex Head Injury Matrix (WHIM). Multi-centric prospective study. To test concurrent validity and diagnostic sensitivity, the four behavioural scales were administered in a randomized order in 77 vegetative and minimally conscious patients. Twenty-four clinicians with different professional backgrounds, levels of expertise and CRS-R experience were recruited to assess inter-rater agreement. Good concurrent validity was obtained between the CRS-R and the three other standardized behavioural scales. Inter-rater reliability for the CRS-R total score and sub-scores was good, indicating that the scale yields reproducible findings across examiners and does not appear to be systematically biased by profession, level of expertise or CRS-R experience. Finally, the CRS-R demonstrated a significantly higher sensitivity to detect MCS patients, as compared to the GCS, the FOUR and the WHIM. The results show that the French version of the CRS-R is a valid and sensitive scale which can be used in severely brain damaged patients by all members of the medical staff.

Objective The aim of this study was to develop a self-diagnostic scale that could distinguish smartphone addicts based on the Korean self-diagnostic program for Internet addiction (K-scale) and the smartphone's own features. In addition, the reliability and validity of the smartphone addiction scale (SAS) was demonstrated. Methods A total of 197 participants were selected from Nov. 2011 to Jan. 2012 to accomplish a set of questionnaires, including SAS, K-scale, modified Kimberly Young Internet addiction test (Y-scale), visual analogue scale (VAS), and substance dependence and abuse diagnosis of DSM-IV. There were 64 males and 133 females, with ages ranging from 18 to 53 years (M = 26.06; SD = 5.96). Factor analysis, internal-consistency test, t-test, ANOVA, and correlation analysis were conducted to verify the reliability and validity of SAS. Results Based on the factor analysis results, the subscale “disturbance of reality testing” was removed, and six factors were left. The internal consistency and concurrent validity of SAS were verified (Cronbach's alpha = 0.967). SAS and its subscales were significantly correlated with K-scale and Y-scale. The VAS of each factor also showed a significant correlation with each subscale. In addition, differences were found in the job (p<0.05), education (p<0.05), and self-reported smartphone addiction scores (p<0.001) in SAS. Conclusions This study developed the first scale of the smartphone addiction aspect of the diagnostic manual. This scale was proven to be relatively reliable and valid. PMID:23468893

Purpose Nurses and other healthcare workers frequently experience belief conflict, one of the most important, new stress-related problems in both academic and clinical fields. Methods In this study, using a sample of 1,683 nursing practitioners, we developed The Assessment of Belief Conflict in Relationship-14 (ABCR-14), a new scale that assesses belief conflict in the healthcare field. Standard psychometric procedures were used to develop and test the scale, including a qualitative framework concept and item-pool development, item reduction, and scale development. We analyzed the psychometric properties of ABCR-14 according to entropy, polyserial correlation coefficient, exploratory factor analysis, confirmatory factor analysis, average variance extracted, Cronbach’s alpha, Pearson product-moment correlation coefficient, and multidimensional item response theory (MIRT). Results The results of the analysis supported a three-factor model consisting of 14 items. The validity and reliability of ABCR-14 was suggested by evidence from high construct validity, structural validity, hypothesis testing, internal consistency reliability, and concurrent validity. The result of the MIRT offered strong support for good item response of item slope parameters and difficulty parameters. However, the ABCR-14 Likert scale might need to be explored from the MIRT point of view. Yet, as mentioned above, there is sufficient evidence to support that ABCR-14 has high validity and reliability. Conclusion The ABCR-14 demonstrates good psychometric properties for nursing belief conflict. Further studies are recommended to confirm its application in clinical practice. PMID:26247356

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 recent years, there has been a great development of esthetic dermatology as a subspecialty of dermatology. It is important to know to which extent the general population regard this branch of medical surgical specialty as being of interest and contributing to emotional well-being. To analyze the technical features of a questionnaire which has been designed to reflect such perception of the general population about esthetic dermatology and its contribution to emotional well-being. Production and psychometric analysis of a self-filled in questionnaire in relation to esthetic dermatology and emotional well-being (DEBIE). This questionnaire is made of 57 items and has been applied to a sample of 770 people within the general population. The drawing-up process of the questionnaire is described to provide content validity. Items analysis was carried out together with exploratory and confirmatory factor analysis to assess the structure and construct validity of the tool. The extent of internal consistency (reliability) and concurrent validity has also been verified. DEBIE questionnaire (Spanish acronym for Aesthetic Dermatology and Emotional Well-being) revolves around six factors explaining 53.91% of the variance; there is a high level of internal consistency (Cronbach's α 0.90) and reasonable criterion validity. DEBIE questionnaire brings together adequate psychometric properties that can be applied to assess the perception that the general population have in relation to esthetic dermatology and its contribution to their emotional well-being. © 2014 Wiley Periodicals, Inc.

Design and Analysis Techniques for Concurrent Blackboard Systems. Ph.D. Thesis

Mcmanus, John William

1992-01-01

Blackboard systems are a natural progression of knowledge-based systems into a more powerful problem solving technique. They provide a way for several highly specialized knowledge sources to cooperate to solve large, complex problems. Blackboard systems incorporate the concepts developed by rule-based and expert systems programmers and include the ability to add conventionally coded knowledge sources. The small and specialized knowledge sources are easier to develop and test, and can be hosted on hardware specifically suited to the task that they are solving. The Formal Model for Blackboard Systems was developed to provide a consistent method for describing a blackboard system. A set of blackboard system design tools has been developed and validated for implementing systems that are expressed using the Formal Model. The tools are used to test and refine a proposed blackboard system design before the design is implemented. My research has shown that the level of independence and specialization of the knowledge sources directly affects the performance of blackboard systems. Using the design, simulation, and analysis tools, I developed a concurrent object-oriented blackboard system that is faster, more efficient, and more powerful than existing systems. The use of the design and analysis tools provided the highly specialized and independent knowledge sources required for my concurrent blackboard system to achieve its design goals.

Surgeries employing arthroscopic techniques are among the most commonly performed in orthopaedic clinical practice; however, valid and reliable methods of assessing the arthroscopic skill of orthopaedic surgeons are lacking. The Arthroscopic Surgery Skill Evaluation Tool (ASSET) will demonstrate content validity, concurrent criterion-oriented validity, and reliability when used to assess the technical ability of surgeons performing diagnostic knee arthroscopic surgery on cadaveric specimens. Cross-sectional study; Level of evidence, 3. Content validity was determined by a group of 7 experts using the Delphi method. Intra-articular performance of a right and left diagnostic knee arthroscopic procedure was recorded for 28 residents and 2 sports medicine fellowship-trained attending surgeons. Surgeon performance was assessed by 2 blinded raters using the ASSET. Concurrent criterion-oriented validity, interrater reliability, and test-retest reliability were evaluated. Content validity: The content development group identified 8 arthroscopic skill domains to evaluate using the ASSET. Concurrent criterion-oriented validity: Significant differences in the total ASSET score (P < .05) between novice, intermediate, and advanced experience groups were identified. Interrater reliability: The ASSET scores assigned by each rater were strongly correlated (r = 0.91, P < .01), and the intraclass correlation coefficient between raters for the total ASSET score was 0.90. Test-retest reliability: There was a significant correlation between ASSET scores for both procedures attempted by each surgeon (r = 0.79, P < .01). The ASSET appears to be a useful, valid, and reliable method for assessing surgeon performance of diagnostic knee arthroscopic surgery in cadaveric specimens. Studies are ongoing to determine its generalizability to other procedures as well as to the live operating room and other simulated environments.

Background: The Snaith-Hamilton Pleasure Scale (SHAPS) is a self-assessment scale designed to evaluate anhedonia in various psychiatric disorders. In order to facilitate its use in Malaysian settings, our current study aimed to examine the validity of a Malay-translated version of the SHAPS (SHAPS-M). Methods: In this cross-sectional study, a total of 44 depressed patients and 82 healthy subjects were recruited from a university out-patient clinic. All participants were given both the Malay and English versions of the SHAPS, Fawcett-Clark Pleasure Scale (FCPS), General Health Questionnaire 12 (GHQ-12), and the Beck Depression Inventory (BDI) to assess their hedonic state, general mental health condition and levels of depression. Results: The results showed that the SHAPS-M has impressive internal consistency (α = 0.96), concurrent validity and good parallel-form reliability (intraclass coefficient, ICC = 0.65). Conclusion: In addition to demonstrating good psychometric properties, the SHAPS-M is easy to administer. Therefore, it is a valid, reliable, and suitable questionnaire for assessing anhedonia among depressed patients in Malaysia. PMID:25246837

Report on the development and psychometric testing of a theoretically and evidence-grounded instrument, the Characteristics of Responsible Drinking Survey (CHORDS). Instrument subjected to four phases of pretesting (cognitive validity, cognitive and motivational qualities, pilot test, and item evaluation) and a final posttest implementation. Large public university in Texas. Randomly selected convenience sample (n  =  729) of currently enrolled students. This 78-item questionnaire measures individuals' responsible drinking beliefs, motivations, intentions, and behaviors. Cronbach α, split-half reliability, principal components analysis and Spearman ρ were conducted to investigate reliability, stability, and validity. Measures in the CHORDS exhibited high internal consistency reliability and strong correlations of split-half reliability. Factor analyses indicated five distinct scales were present, as proposed in the theoretical model. Subscale composite scores also exhibited a correlation to alcohol consumption behaviors, indicating concurrent validity. The CHORDS represents the first instrument specifically designed to assess responsible drinking beliefs and behaviors. It was found to elicit valid and reliable data among a college student sample. This instrument holds much promise for practitioners who desire to empirically investigate dimensions of responsible drinking.

2015-05-01

To determine the validity and reliability of the Exercise Resourcefulness Inventory (ERI) designed to assess the self-regulatory strategies used to promote regular exercise. In Study 1, the inventory's relationship with other established scales in the exercise behavior change field was examined. In Study 2, the test-retest reliability and predictive validity of the ERI was established by having participants from Study 1 complete the inventory a second time. Internal consistency, and convergent, discriminant, and concurrent validity were supported in both studies. The test-retest correlation of the ERI was .80. As well, participants scoring higher on the ERI in Study 1 were more likely to be at a higher stage of change in Study 2, and greater increases in exercise resourcefulness over time were predictive of advancement to higher stages of change. ERI is a reliable and valid measure to assess the self-regulatory strategies used to promote regular exercise. Facilitators may want to tailor exercise programs for individuals scoring lower in resourcefulness to prevent them from relapsing. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The objective of this study was to develop a pediatric measure of chronic nausea severity, the Nausea Severity Scale (NSS), and evaluate its reliability and validity in youth with abdominal pain-related functional gastrointestinal disorders (AP-FGID). Pediatric patients (aged 11⁻17 years-old, n = 236) presenting to an outpatient clinic for evaluation of abdominal pain completed the NSS, Children's Somatization Inventory (CSI), Functional Disability Inventory (FDI), Abdominal Pain Index (API), Patient-Report Outcomes Measurement Information System (PROMIS), Anxiety and Depression Scales and the Pediatric Rome III Questionnaire for FGIDs. The NSS demonstrated good concurrent, discriminant, and construct validity, as well as good internal consistency. One-third (34%) of AP-FGID patients reported experiencing nausea "most" or "every day" in the previous two weeks. The severity of nausea was higher in females than males and correlated significantly with the severity of somatic symptoms, functional disability, anxiety, and depression. The NSS is a valid and reliable measure of nausea in children with AP-FGID.

Toward the development of a children's science curiosity measure

NASA Astrophysics Data System (ADS)

Harty, Harold; Beall, Dwight

Based on the need for, suggestions about the construction, and existing measures serving as models found in the literature both inside and outside of science education, the Children's Science Curiosity Scale has undergone six versions using four different samples of fifth graders. Respectable internal consistency (alpha) and test-retest reliabilities have been calculated. Concurrent validity has been demonstrated by significant positive correlations with another recognized curiosity measure, and by way of significant differences between students who were interested in science and students uncertain about interest in science. Somewhat weak predictive validity has been decided by way of significant positive correlations with students' semester science grades. Construct validity has been described and established by eight judges using six criteria, and supported through the use of factor analysis where four underlying factors were hypothesized as characteristics of science curiosity. Sex differences were also explored where significant differences were not found between the genders. Suggestions have been made concerning future attempts at instrument refinement, establishing conceptual validity, future research involving other variables, and classroom use in a variety of contexts.

Construct, concurrent and discriminant validity of Type D personality in the general population: associations with anxiety, depression, stress and cardiac output.

PubMed

Howard, Siobhán; Hughes, Brian M

2012-01-01

The Type D personality, identified by high negative affectivity paired with high social inhibition, has been associated with a number of health-related outcomes in (mainly) cardiac populations. However, despite its prevalence in the health-related literature, how this personality construct fits within existing personality theory has not been directly tested. Using a sample of 134 healthy university students, this study examined the Type D personality in terms of two well-established personality traits; introversion and neuroticism. Construct, concurrent and discriminant validity of this personality type was established through examination of the associations between the Type D personality and psychometrically assessed anxiety, depression and stress, as well as measurement of resting cardiovascular function. Results showed that while the Type D personality was easily represented using alternative measures of both introversion and neuroticism, associations with anxiety, depression and stress were mainly accounted for by neuroticism. Conversely, however, associations with resting cardiac output were attributable to the negative affectivity-social inhibition synergy, explicit within the Type D construct. Consequently, both the construct and concurrent validity of this personality type were confirmed, with discriminant validity evident on examination of physiological indices of well-being.

Validity of clinical outcome measures to evaluate ankle range of motion during the weight-bearing lunge test.

Hall, Emily A; Docherty, Carrie L

2017-07-01

To determine the concurrent validity of standard clinical outcome measures compared to laboratory outcome measure while performing the weight-bearing lunge test (WBLT). Cross-sectional study. Fifty participants performed the WBLT to determine dorsiflexion ROM using four different measurement techniques: dorsiflexion angle with digital inclinometer at 15cm distal to the tibial tuberosity (°), dorsiflexion angle with inclinometer at tibial tuberosity (°), maximum lunge distance (cm), and dorsiflexion angle using a 2D motion capture system (°). Outcome measures were recorded concurrently during each trial. To establish concurrent validity, Pearson product-moment correlation coefficients (r) were conducted, comparing each dependent variable to the 2D motion capture analysis (identified as the reference standard). A higher correlation indicates strong concurrent validity. There was a high correlation between each measurement technique and the reference standard. Specifically the correlation between the inclinometer placement at 15cm below the tibial tuberosity (44.9°±5.5°) and the motion capture angle (27.0°±6.0°) was r=0.76 (p=0.001), between the inclinometer placement at the tibial tuberosity angle (39.0°±4.6°) and the motion capture angle was r=0.71 (p=0.001), and between the distance from the wall clinical measure (10.3±3.0cm) to the motion capture angle was r=0.74 (p=0.001). This study determined that the clinical measures used during the WBLT have a high correlation with the reference standard for assessing dorsiflexion range of motion. Therefore, obtaining maximum lunge distance and inclinometer angles are both valid assessments during the weight-bearing lunge test. Copyright © 2016 Sports Medicine Australia.

Wearable inertial measurement systems (IMS) allow for three-dimensional analysis of human movements in a sport-specific setting. This study examined the concurrent validity of a IMS (Xsens MVN system) for measuring lower extremity and pelvis kinematics in comparison to a Vicon motion analysis system (MAS) during kicking. Thirty footballers from Australian football (n = 10), soccer (n = 10), rugby league and rugby union (n = 10) clubs completed 20 kicks across four conditions. Concurrent validity was assessed using a linear mixed-modelling approach, which allowed the partition of between and within-subject variance from the device measurement error. Results were expressed in raw and standardised units for assessments of differences in means and measurement error, and interpreted via non-clinical magnitude-based inferences. Trivial to small differences were found in linear velocities (foot and pelvis), angular velocities (knee, shank and thigh), sagittal joint (knee and hip) and segment angle (shank and pelvis) means (mean difference: 0.2-5.8%) between the IMS and MAS in Australian football, soccer and the rugby codes. Trivial to small measurement errors (from 0.1 to 5.8%) were found between the IMS and MAS in all kinematic parameters. The IMS demonstrated acceptable levels of concurrent validity compared to a MAS when measuring kicking biomechanics across the four football codes. Wearable IMS offers various benefits over MAS, such as, out-of-laboratory testing, larger measurement range and quick data output, to help improve the ecological validity of biomechanical testing and the timing of feedback. The results advocate the use of IMS to quantify biomechanics of high-velocity movements in sport-specific settings. Copyright © 2018 Elsevier Ltd. All rights reserved.

To investigate the reliability and concurrent validity of the Baseline ® Body Level/Scoliosis meter for adolescent idiopathic scoliosis postural assessment in three anatomical planes. This is an observational reliability and concurrent validity study of adolescent referrals to the Orthopaedic department for scoliosis screening at Karolinska University Hospital, Stockholm, Sweden between March-May 2012. A total of 31 adolescents with idiopathic scoliosis (13.6 ± 0.6 years old) of mild-moderate curvatures (25° ± 12°) were consecutively recruited. Measurement of cervical, thoracic and lumbar curvatures, pelvic and shoulder tilt, and axial thoracic rotation (ATR) were performed by two trained physiotherapists in one day. The intraclass correlation coefficient (ICC) was used to determine the inter-examiner reliability (ICC2,1) and the intra-rater reliability (ICC3,3) of the Baseline ® Body Level/Scoliosis meter. Spearman's correlation analyses were used to estimate concurrent validity between the Baseline ® Body Level/Scoliosis meter and Gold Standard Cobb angles from radiographs and the Orthopaedic Systems Inc. Scoliometer. There was excellent reliability between examiners for thoracic kyphosis (ICC2,1 = 0.94), ATR (ICC2,1 = 0.92) and lumbar lordosis (ICC2,1 = 0.79). There was adequate reliability between examiners for cervical lordosis (ICC2,1 = 0.51), however poor reliability for pelvic and shoulder tilt. Both devices were reproducible in the measurement of ATR when repeated by one examiner (ICC3,3 0.98-1.00). The device had a good correlation with the Scoliometer (rho = 0.78). When compared with Cobb angle from radiographs, there was a moderate correlation for ATR (rho = 0.627). The Baseline ® Body Level/Scoliosis meter provides reliable transverse and sagittal cervical, thoracic and lumbar measurements and valid transverse plan measurements of mild-moderate scoliosis deformity.

A number of diagnostic scales or questionnaires have been developed in recent years, to assess mobile phone dependency. A valid and reliable assessment instrument for correspondence of Iranian culture is essential. The aim of our study is to validate the Iranian version of the Cell Phone Dependency Questionnaire (CPDQ). In this cross-sectional study, data were collected from 784 students, who were studying in four main Isfahan Universities. The participants completed the demographic questionnaire, CPDQ, anonymously. To analyze the data we used concurrent validity, factor analysis, internal consistency, split-half, and test-retest. We extracted three factors including Salience, Overusing of the cell phone, compulsive use of SMS. Cronbach's alpha of the CPDQ was. 88 (Cronbach's alpha of the factors were 0.85, 0.70, and 0.76, respectively). The CPDQ proved to be a reliable questionnaire to assess the extent of problems caused by the 'misuse' of the cell phone in Iranian society.

We evaluated the psychometric properties of the Korean version of the Self-Efficacy for Exercise Scale (SEE-K). The SEE-K consists of nine items and was translated into Korean using the forward-backward translation method. We administered it to 212 community-dwelling older adults along with measures of outcome expectation for exercise, quality of life, and physical activity. The validity was determined using confirmatory factor analysis and Rasch analysis with INFIT and OUTFIT statistics, which showed acceptable model fit. The concurrent validity was confirmed according to positive correlations between the SEE-K, outcome expectation for exercise, and quality of life. Furthermore, the high physical activity group had higher SEE-K scores. Finally, the reliability of the SEE-K was deemed acceptable based on Cronbach's alpha, coefficients of determination, and person and item separation indices with reliability. Thus, the SEE-K appears to have satisfactory validity and reliability among older adults in South Korea. Copyright © 2015 Elsevier Inc. All rights reserved.

The Positions on Nursing Diagnosis (PND) is a scale that uses the semantic differential technique to measure nurses' attitudes towards the nursing diagnosis concept. The aim of this study was to develop a shortened form of the Spanish version of this scale and evaluate its psychometric properties and efficiency. A double theoretical-empirical approach was used to obtain a short form of the PND, the PND-7-SV, which would be equivalent to the original. Using a cross-sectional survey design, the reliability (internal consistency and test-retest reliability), construct (exploratory factor analysis, known-groups technique and discriminant validity) and criterion-related validity (concurrent validity), sensitivity to change and efficiency of the PND-7-SV were assessed in a sample of 476 Spanish nursing students. The results endorsed the utility of the PND-7-SV to measure attitudes toward nursing diagnosis in an equivalent manner to the complete form of the scale and in a shorter time.

Adherence to HIV treatment, including adherence to antiretroviral (ART) medication regimens, is paramount in the management of HIV. Self-efficacy for treatment adherence has been identified as an important correlate of medication adherence in the treatment of HIV and other medical conditions. This paper describes the validation of the HIV Treatment Adherence Self-Efficacy Scale (HIV-ASES) with two samples of HIV+ adults on ART. Factor analyses support subscales measuring Adherence Integration (eigenvalue = 6.12) and Adherence Perseverance (eigenvalue = 1.16), accounting for 61% of the variance in scale items. The HIV-ASES demonstrates robust internal consistency (ρs > .90) and 3-month (rs > .70) and 15-month (rs > .40) test-retest reliability. Concurrent validity analyses revealed relationships with psychosocial measures, ART adherence, clinical status, and healthcare utilization. Findings support the use of the HIV-ASES and provide guidance for further investigation of adherence self-efficacy in the context of treatment for HIV and other diseases. PMID:17588200

The present study examined the psychometric properties and factor structure of English and Malay version of the Reasons For Living (RFL) Inventory in a sample of clinical outpatients in Malaysia. The RFL is designed to assess an individual's various reasons for not committing suicide. A total of 483 participants (283 with psychiatric illnesses and 200 with non-psychiatric medical illnesses) completed the RFL and other self-report instruments. Results of the EFA (exploratory factor analysis) and CFA (confirmatory factor analysis) supported the fit for the six-factor oblique model as the best-fitting model. The internal consistency of the RFL was α=.94 and it was found to be high with good concurrent, criterion and discriminative validities. Thus, the RFL is a reliable and valid instrument to measure the various reasons for not committing suicide among psychiatry and medical outpatients in Malaysia. © 2014.

Purpose To define the concept of “health care insecurity,” validate a new self-report measure, and examine the impact of beginning care at a free clinic on uninsured patients’ health care insecurity. Methods Consecutive new patients presenting at a free clinic completed 15 items assessing domains of health care insecurity (HCI) at their first visit and again four to eight weeks later. Psychometrics and change of the HCI measure were examined. Results The HCI measure was found to have high internal consistency (α=0.94). Evidence of concurrent validity was indicated by negative correlation with VR-12 health-related quality of life physical and mental health components and positive correlation with the Perceived Stress Scale. Predictive validity was shown among the 83% of participants completing follow-up: HCI decreased after beginning care at a free clinic (p<.001). Conclusion Reliably assessing patient experience of health care insecurity is feasible and has potential to inform efforts to improve quality and access to care among underserved populations.

Akada, Taro

2010-06-01

This study describes the development and evaluation of the Nursery Teacher's Stress Scale (NTSS), which explores the relation between daily hassles at work and work-related stress. In Analysis 1, 29 items were chosen to construct the NTSS. Six factors were identified: I. Stress relating to child care; II. Stress from human relations at work; III. Stress from staff-parent relations; IV. Stress from lack of time; V. Stress relating to compensation; and VI. Stress from the difference between individual beliefs and school policy. All these factors had high degrees of internal consistency. In Analysis 2, the concurrent validity of the NTSS was examined. The results showed that the NTSS total scores were significantly correlated with the Job Stress Scale-Revised Version (job stressor scale, r = .68), the Pre-school Teacher-efficacy Scale (r = -.21), and the WHO-five Well-Being Index Japanese Version (r = -.40). Work stresses are affected by several daily hassles at work. The NTSS has acceptable reliability and validity, and can be used to improve nursery teacher's mental health.

A questionnaire was developed and validated which assesses factors influencing career choices of medical students and their perception of possibilities in general practice. The first questionnaire version, which was developed based on a systematic literature review, was checked for comprehensibility and redundancy using concurrent think aloud. The revised version was filled out by a pilot sample of medical students and the factor structure was assessed using principal component analysis (PCA). The final version was filled out in an online survey by medical students of all 5 Medical Faculties in the federal state of Baden-Wuerttemberg. The factor structure was validated with a confirmatory factor analysis (CFA). Reliability was assessed as internal consistency using Cronbach's α. The questionnaire comprises 2 parts: ratings of (A) the individual importance and of (B) the possibilities in general practice on 5-point scales. The first version comprising 118 items was shortened to 63 items after conducting interviews using concurrent think aloud. A further 3 items giving no information were removed after piloting the questionnaire on 179 students. The 27 items of part A were structured in 7 factors (PCA): image, personal ambition, patient orientation, work-life balance, future perspectives, job-related ambition, and variety in job. This structure had a critical fit in the CFA applied to the final version filled out by 1 299 students. Internal consistency of the factors was satisfactory to very good (Cronbach's α=0.55-0.81). The questionnaire showed good psychometric properties. Further, not assessed factors influence career choice resulting in unexplained variance in our dataset and the critical fit of the model. © Georg Thieme Verlag KG Stuttgart · New York.

A psychometric evaluation of the Needs and Provision Complexity Scale (NPCS). The NPCS is designed to evaluate both needs for health and social support (NPCS-Needs) and services provided to meet those needs (NPCS-Gets). A consecutive cohort of patients were recruited from nine specialist neurorehabilitation units in London. Four hundred and twenty-eight patients were assessed at discharge (63.1% males; mean age 49 years) of whom 73.6% had acquired brain injury (49.5% stroke/subarachnoid, 14.7% traumatic brain injury, 9.3% 'other acquired brain injury'), 8.9% spinal cord injury, 6.1% peripheral neuropathy, 4.9% progressive neurological and 6.3% other neurological conditions. The NPCS-Needs was completed by the clinical team at discharge and 212 patients reported NPCS-Gets after six months. NPCS-Gets repeatability was tested in a subsample (n = 60). Factor analysis identified two principal domains ('Health and personal care' and 'Social care and support') accounting for 66% of variance, and suggested a large general factor underpinning the NPCS. Internal consistency was high (alpha = 0.94) and repeatability acceptable. Intraclass coefficients for domain scores were healthcare 0.67 (95% confidence interval (CI) 0.48-0.80); personal care 0.83 (0.73-0.90); rehabilitation 0.65 (0.45-0.78); social/family support 0.66 (0.46-0.79) and environment 0.84 (0.74-0.90). Linear-weighted kappas for item-by-item agreement ranged from 0.42 to 0.83. Concurrent validity was demonstrated through correlations with measures of dependency and community integration. Notwithstanding a 50% response rate after six months, the NPCS has good internal consistency, a robust two-factor structure, acceptable test-retest reliability and initial evidence of concurrent validity. © The Author(s) 2014.

Objectives Older adults prefer to remain in their own homes for as long as possible. The purpose of this article is to describe the development and preliminary validation of Making and Executing Decisions for Safe and Independent Living (MED-SAIL), a brief screening tool for capacity to live safely and independently in the community. Design Prospective preliminary validation study. Setting Outpatient geriatrics clinic located in a community-based hospital. Participants Forty-nine community-dwelling older adults referred to the clinic for a comprehensive capacity assessment. Measurements We examined internal consistency, criterion-based validity, concurrent validity, and accuracy of classification for MED-SAIL. Results The items included in MED-SAIL demonstrated internal consistency (5 items; α = 0.85). MED-SAIL was significantly correlated with the Independent Living Scales (r = 0.573, p ≤ 0.001) and instrumental activities of daily living (r = 0.440, p ≤ 0.01). The Mann-Whitney U test revealed significant differences between the no capacity and partial/full capacity classifications on MED-SAIL (U(48) = 60.5, Z = −0.38, p <0.0001). The area under the curve was 0.864 (95% confidence interval: 0.84–0.99). Conclusions This study demonstrated the validity of MED-SAIL as a brief screening tool to identify older adults with impaired capacity for remaining safe and independent in their current living environment. MED-SAIL is useful tool for health and social service providers in the community for the purpose of referral for definitive capacity evaluation. PMID:23567420

This investigation presents two studies with the goal of adapting and validating a short version of the Group Environment Questionnaire in the Spanish sport context with professional players. Study 1 used a sample of 377 male soccer players aged between 18 and 39 years ( M = 24.51, SD = 3.73), in a preliminary study using exploratory factor analysis. Study 2 used a sample of 604 professional male and female athletes, ages between 15 and 38 years ( M = 24.34, SD = 4.03). The data analyzed were collected at three moments of the season. For each measurement, we developed seven first- and second-order structures that were analyzed with confirmatory factor analysis. Study 1 indicated appropriate factorial validity (> .60) and internal consistency (> .70), with only Item 3 presenting a low factor loading (.11), so its drafting was modified in the next study. Study 2 revealed that the Spanish version of the GEQ has high levels of internal consistency (> .70) and acceptable fit index values in its original four first-order factor structure in all three measurements ( χ²/df = 4.39, CFI = .95, IFI = .95, RMSEA = .07, SRMR = .04, AIC = 271.09). Discriminant validity (from r = .45 to r = .72) and concurrent validity (from r = .21 to r = .60) also presented appropriate values. Lastly, we conducted analysis of invariance, confirming that the models established in the different measurements were invariant. The short 12-item adaptation of the GEQ to Spanish is a valid and reliable instrument to measure team cohesion in professional male and female soccer players.

The purposes of this study were to evaluate the psychometric properties, reliability, and validity of the Chinese-version Glover-Nilsson Smoking Behavioral Questionnaire (GN-SBQ-C) and assess the behavioral nicotine dependence among community-dwelling adult smokers in Taiwan. The methods used were survey design, administration, and validation. A total of 202 adult smokers completed a survey to assess behavioral dependence, nicotine dependence, depression, social support, and demographic and smoking characteristics. Data analysis included descriptive statistics, internal consistency reliability, t test, exploratory factor analysis, independent t test, and Pearson product moment correlation. The results showed that (1) the GN-SBQ-C has good internal consistency reliability and stability (2-week test-retest reliability); (2) the extracted one factor explained 41.80 % of the variance, indicating construct validity; (3) the scale has acceptable concurrent validity, with significant positive correlation between the GN-SBQ-C and nicotine dependence, depression, and time smoking and negative correlation between the GN-SBQ-C and age and exercise habit; and (4) the instrument has discriminant validity, supported by significant differences between those with high and low-to-moderate nicotine dependence, smokers greater than 43 years old and those 43 years old and younger, and those who smoked 10 years or less and those smoking more than 10 years. The 11-item GN-SBQ-C has satisfactory psychometric properties when applied in a sample of Taiwanese adult smokers. The scale is feasible and valid to use to assess smoking behavioral dependence.

The objective of the study is to evaluate the psychometric properties of the Gaming Addiction Identification Test (GAIT) and its parent version (GAIT-P), in a representative community sample of adolescents and parents in Västmanland, Sweden. Self-rated and parent-rated gaming addictive symptoms identified by GAIT and GAIT-P were analyzed for frequency of endorsement, internal consistency, concordance, factor structure, prevalence of Internet gaming disorder (IGD), concurrence with the Gaming Addiction Scale for Adolescents, 7-item version (GAS) and the parent version of GAS (GAS-P), and for sex differences. The 12-month prevalence of IGD was found to be 1.3% with GAIT and 2.4% with GAIT-P. Results also indicate promising psychometric results within this population, with high internal consistency, and high concurrent validity with GAS and GAS-P. Concordance between adolescents and parents ratings was high, although moderate in girls. Although exploratory factor analysis indicated poor model fit, it also indicated unidimensionality and high factor loadings in all analyses. GAIT and GAIT-P are suitable for continued use in measuring gaming addiction in adolescents, and, with the additional two items, they now cover all nine IGD criteria. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

A study of affective temperaments in Hungary: internal consistency and concurrent validity of the TEMPS-A against the TCI and NEO-PI-R.

TEMPS-A (Temperament Evaluation of the Memphis, Pisa, Paris and San Diego - Autoquestionnaire) is a new self-assessed temperament 110-item scale with depressive (D), cyclothymic (C), hyperthymic (H), irritable (I) and anxious (A) subscales. To date, it has been translated into 25 languages, and validated in 10. The present Hungarian version provides the most complete external validation across the Beck Depression Scale (BDI), Profile of Mood States (POMS), the BarOn Emotional Quotient Inventory (BarOn EQ-i), Temperament and Character Inventory (TCI), and the NEO Personality Inventory - Revised (NEO-PI-R). We were particularly interested in concurrent validation against the TCI and the NEO-PI-R, the most important of the new personality instruments. 1132 clinically-well subjects (27% male) from the general population and university students (16-81 years) were administered the above scales and instruments. The data were tested with standard psychometric batteries. Factor analysis revealed 5 factors approximating the original D, C, I, H, and A subscales, which in their superfactor confirmed an Emotional (D, C, I, A) vs. Hyperthymic structure. Except for the D (a=0.65), the Cronbach alpha for the remainder temperaments ranged from 0.75-0.81. Dominant temperaments ranged from the I (2.7%) to the C (4.2%); the highest prevalence was observed among men with C=6% and H=5.4%. The BDI and POMS correlated significantly with the relevant subscales, as did the BarOn. Of the many significant possible correlations with the TCI, the most noteworthy were novelty seeking and harm avoidance with D, A, C, as well as C, and persistence with H. As for the NEO-PI-R, we were struck by the positive correlation of openness with C, and conscientiousness negatively with C; most other positive correlations such as neuroticism with all temperaments but the hyperthymic were expected and strongly supportive of concurrent validity. Higher educational background of the subjects studied relative to that of the general population of Hungary. The distribution of the data may have in some instances deviated somewhat from the underlying assumptions for the standard psychometric tests for normality. We did not conduct test-retest reliability. The factorial structure of the TEMPS-A shows good reliability and internal consistency. Although the superstructure is reminiscent of neuroticism-extraversion, within it are embedded discernible classical affective temperaments. A provocative finding is the high prevalence of cyclothymia in Hungarian males (6%), which is rather unique when compared with the other 10 countries studied to date. This finding, coupled with high male hyperthymia (5.4%), may explain the high lifetime prevalence of bipolar disorders reported from Hungary. Inter alia, our psychometric data along with the foregoing epidemiologic considerations, are very much in line with the cyclothymic-bipolar spectrum model proposed by the senior author [Akiskal, H.S., Djenderedjian, A.H., Rosenthal, R.H., Khani, M.K., 1977. Cyclothymic disorder: validating criteria for inclusion in the bipolar affective group. Am. J. Psychiatry 134, 1227-1233].

To undertake a comparative examination of the reliability and validity of two frequently used self-report measures of functional disability, the Pain Disability Index (PDI) and the Oswestry Low Back Pain Disability Questionnaire (OLBPDQ). A descriptive ex-post facto design was used in the study. Pain clinics and neurosurgical units at three metropolitan hospitals. One hundred patients with chronic low back pain of noncancer origin were administered the two questionnaires as part of a larger questionnaire battery. Acceptable internal consistency values of 0.76 for the PDI and 0.71 for the OLBPDQ were obtained. A correlation of r = 0.63 was found between the PDI and the OLBPDQ, supporting the concurrent validity of the two scales. Both the scales were found to be correlated to the Beck Depression Inventory scores (PDI, r = 0.42; OLBPDQ, r = 0.39), with higher disability associated with greater depression. Only the total PDI score was found to be sensitive to functional status differences within the patient sample. These findings support other recent work in favor of the PDI. The PDI had a slightly higher internal consistency and was more sensitive than the OLBPDQ.

To evaluate the validity, reliability, and cultural relevance of the Chinese Mandarin version of Myocardial Infarction Dimensional Assessment Scale (MIDAS) as a disease-specific quality of life measure. The cultural relevance and content validity of the Chinese Mandarin version of the MIDAS (CM-MIDAS) was evaluated by an expert panel. Measurement performance was tested on 180 randomly selected Chinese MI patents. Thirty participants from the primary group completed the CM-MIDAS for test-retest reliability after 2 weeks. Reliability, validity and discriminatory power of the CM-MIDAS were calculated. Two items were modified as suggested by the expert panel. The overall CM-MIDAS had acceptable internal consistency with Cronbach's alpha coefficient 0.93 for the scale and 0.71-0.94 for the seven domains. Test-retest reliability by intraclass correlations was 0.85 for the overall scale and 0.74-0.94 for the seven domains. There was acceptable concurrent validity with significant (p < 0.05) correlations between the CM-MDAS and the Chinese Version of the Short Form 36. The principal components analysis extracted seven factors that explained 67.18% of the variance with high factor loading indicating good construct validity. Empirical data support CM-MIDAS as a valid and reliable disease-specific quality of life measure for Chinese Mandarin speaking patients with myocardial infarction.

Posturography systems that incorporate force platforms are considered to assess balance and postural control with greater sensitivity and objectivity than conventional clinical tests. The Wii Balance Board (WBB) system has been shown to have similar performance characteristics as other force platforms, but with lower cost and size. To determine the validity and reliability of a freely available WBB-based posturography system that combined the WBB with several traditional balance assessments, and to assess the performance of a cohort of stroke individuals with respect to healthy individuals. Healthy subjects and individuals with stroke were recruited. Both groups were assessed using the WBB-based posturography system. Individuals with stroke were also assessed using a laboratory grade posturography system and a battery of clinical tests to determine the concurrent validity of the system. A group of subjects were assessed twice with the WBB-based system to determine its reliability. A total of 144 healthy individuals and 53 individuals with stroke participated in the study. Concurrent validity with another posturography system was moderate to high. Correlations with clinical scales were consistent with previous research. The reliability of the system was excellent in almost all measures. In addition, the system successfully characterized individuals with stroke with respect to the healthy population. The WBB-based posturography system exhibited excellent psychometric properties and sensitivity for identifying balance performance of individuals with stroke in comparison with healthy subjects, which supports feasibility of the system as a clinical tool.

Recently, an 8-item short-form version of the Chronic Pain Acceptance Questionnaire (CPAQ-8) was developed predominantly in an internet sample. Further investigation of the factor structure in a multidisciplinary pain clinic sample is required. Investigation of the concurrent validity of the CPAQ-8 after accounting for the effects of variables commonly measured in the pain clinic setting is also necessary. This study examines the factor structure and concurrent validity of the CPAQ-8 in a sample of treatment-seeking patients who attended a multidisciplinary pain clinic. Participants were 334 patients who attended an Australian multidisciplinary pain service. Participants completed the CPAQ, a demographic questionnaire, and measures of patient adjustment and functioning. Confirmatory factor analysis identified a two-factor 8-item model consisting of Activity Engagement and Pain Willingness factors (SRMR = 0.039, RMSEA = 0.063, CFI = 0.973, TLI = 0.960) was superior to both the CPAQ and CPAQ with an item removed. The CPAQ and CPAQ-8 total scores were highly correlated (r = 0.93). After accounting for pain intensity, the CPAQ-8 was a significant predictor of depression, anxiety, stress, and disability. The subscales of the CPAQ-8 were both unique contributors to depression and disability in regression analyses, after accounting for pain intensity and kinesiophobia, and after accounting for pain intensity and catastrophizing. The CPAQ-8 has a sound factor structure and similar psychometric properties to the CPAQ; it may have clinical utility as a measure of pain acceptance in treatment-seeking, chronic pain patients.

Study Design : Repeated measures reliability/validity study. Objectives : To determine the concurrent validity, test-retest, inter-rater and intra-rater reliability of lumbar flexion and extension measurements using the Tracker M.E. computerized dual inclinometer (CDI) in comparison to the modified-modified Schober (MMS) Summary of Background : Numerous studies have evaluated the reliability and validity of the various methods of measuring spinal motion, but the results are inconsistent. Differences in equipment and techniques make it difficult to correlate results. Methods : Twenty subjects with back pain and twenty without back pain were selected through convenience sampling. Two examiners measured sagittal plane lumbar range of motion for each subject. Two separate tests with the CDI and one test with the MMS were conducted. Each test consisted of three trials. Instrument and examiner order was randomly assigned. Intra-class correlations (ICCs 2, 2 and 2, 2) and Pearson correlation coefficients (r) were used to calculate reliability and concurrent validity respectively. Results : Intra-trial reliability was high to very high for both the CDI (ICCs 0.85 - 0.96) and MMS (ICCs 0.84 - 0.98). However, the reliability was poor to moderate, when the CDI unit had to be repositioned either by the same rate (ICCs 0.16 - 0.59) or a different rater (ICCs 0.45 - 0.52). Inter-rater reliability for the MMS was moderate to high (ICCs 0.75 - 0.82) which bettered the moderate correlation obtained for the CDI (ICCs 0.45 - 0.52). Correlations between the CDI and MMS were poor for flexion (0.32; p<0.05) and poor to moderate (-0.42 - -0.51; p<0.05) for extension measurements. Conclusion : When using the CDI, an average of subsequent tests is required to obtain moderate reliability. The MMS was highly reliable than the CDI. The MMS and the CDI measure lumbar movement on a different metric that are not highly related to each other. PMID:25352928

To examine the internal consistency, test-retest reliability, validity, and responsiveness of the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire in persons with upper limb amputation. Cross-sectional and longitudinal. Three sites participating in the U.S. Department of Veterans Affairs Home Study of the DEKA Arm. A convenience sample of upper limb amputees (N=44). Training with a multifunction upper limb prosthesis. Multiple outcome measures including the QuickDASH were administered twice within 1 week, and for a subset of 20 persons, after completion of in-laboratory training with the DEKA Arm. Scale alphas and intraclass correlation coefficient type 3,1 (ICC3,1) were used to examine reliability. Minimum detectable change (MDC) scores were calculated. Analyses of variance, comparing QuickDASH scores by the amount of prosthetic use and amputation level, were used for known-group validity analyses with alpha set at .05. Pairwise correlations between QuickDASH and other measures were used to examine concurrent validity. Responsiveness was measured by effect size (ES) and standardized response mean (SRM). QuickDASH alpha was .83, and ICC was .87 (95% confidence interval, .77-.93). MDC at the 95% confidence level (MDC95%) was 17.4. Full- or part-time prosthesis users had better QuickDASH scores compared with nonprosthesis users (P=.021), as did those with more distal amputations at both baseline (P=.042) and with the DEKA Arm (P=.024). The QuickDASH was correlated with concurrent measures of activity limitation as expected. The ES and SRM after training with the DEKA Arm were 0.6. This study provides evidence of reliability and validity of the QuickDASH in persons with upper limb amputation. Results provide preliminary evidence of responsiveness to prosthetic device type/training. Further research with a larger sample is needed to confirm results.

The World Health Organization Five Well-Being Index (WHO-5) has been developed to measure psychological wellbeing. Translation and linguistic validation of the WHO-5 into a Cantonese version has been accomplished for local use but it is not yet validated in people with severe mental illness in Hong Kong. This study aimed to examine the applicability of WHO-5 in measuring the psychological wellbeing dimension of people with severe mental illness. A brief and easily administrated tool to measure psychological wellbeing of people with severe mental illness can be used to provide an outcome measure in research studies and clinical trials. Subjects were randomly recruited from the Extended-Care Patient Intensive Treatment, Early Diversion and Rehabilitation Stepping-Stone Project (EXITERS) and the Rehabilitation Activity Centre (RAC) of Kwai Chung Hospital in Hong Kong. They were invited to complete the abbreviated version of Hong Kong Chinese World Health Organization Quality of Life (WHOQOL-BREF [HK]) and WHO-5 (Cantonese version) separately and concurrent validity was examined. A total of 84 subjects were recruited, 42 each from EXITERS and RAC. In all, 49 (58%) were male and 35 (42%) were female. The mean ± standard deviation age was 43.2 ± 9.7 years. Their mean duration of mental illness was 16.4 ± 10.5 years and the mean years of education was 10.17 ± 2.5 years, i.e. about junior secondary school level in Hong Kong. The internal consistency of the WHO-5 was satisfactory (0.86) and was comparable with previous reports. Regarding validity, 1-factor structure with an eigenvalue of 3.24 explained 64.8% of total variance of WHO-5 for people with severe mental illness. Concurrent validity was established with moderate correlation (0.41-0.51) between WHO-5 and 4 domains of the WHOQOL-BREF (HK). The WHO-5 (Cantonese version) is a reliable and valid tool to assess the psychological wellbeing of people with severe mental illness in Hong Kong. It can be used to monitor the effectiveness of psychological intervention aimed at improving the wellbeing of such patients.

Quality of life is often considered when deciding and evaluating the treatment strategy for patients diagnosed with anal fistula. The purpose of this study was to develop and psychometrically test the Quality of Life in Patients with Anal Fistula Questionnaire. This was an observational cross-sectional study for the development and validation of a psychometric tool. The study was conducted at a general hospital in the southeast of Spain. A convenience sample included 54 patients diagnosed with anal fistula. The reliability of the tool was assessed through its internal consistency (Cronbach α) and temporal stability (Spearman correlation coefficient (r) between test-retest). The content validity index of the items and the scale was calculated. Correlation analysis and an ordinal regression analysis between the developed tool and the Short Form 12 Health Survey examined its concurrent validity. Principal component analysis and known-group analysis using the Kruskal-Wallis test examined its construct validity. The reliability of the developed questionnaire was very high (α = 0.908; r = 0.861; p < 0.01). Its content validity was excellent (all-item content validity index = 0.79-1.00; scale validity index = 0.92). Evidence of its concurrent validity included strong correlation between the developed tool and Short Form 12 Health Survey (r = 0.734; p < 0.001), and participant scores on the developed tool explained ≈46.2% of the between-subject variation for the participant scores on Short Form 12 Health Survey (Nagelkerke R = 0.462). Confirming its construct validity, principal component analysis revealed that 2 factors explained 81.63% of the total variance found. Known-group analysis evidenced the ability of the questionnaire to detect expected differences in patients presenting with different symptomatology. The major limitations of this study were the use of a small sample of Spanish-speaking patients, not including patients in the initial development of the questionnaire, and developing the scoring system using a summation method. The Quality of Life in Patients with Anal Fistula Questionnaire has proven to be a valid, reliable, and concise tool that could contribute to the evaluation of quality of life among patients with an anal fistula.

We developed and tested a College Environmental Perceptions Survey (CEPS) to assess college students' perceptions of the healthfulness of their campus. CEPS was developed in 3 stages: questionnaire development, validity testing, and reliability testing. Questionnaire development was based on an extensive literature review and input from an expert panel to establish content validity. Face validity was established with the target population using cognitive interviews with 100 college students. Concurrent-criterion validity was established with in-depth interviews (N = 30) of college students compared to surveys completed by the same 30 students. Surveys completed by college students from 8 universities (N = 1147) were used to test internal structure (factor analysis) and internal consistency (Cronbach's alpha). After development and testing, 15 items remained from the original 48 items. A 5-factor solution emerged: physical activity (4 items, α = .635), water (3 items, α = .773), vending (2 items, α = .680), healthy food (2 items, α = .631), and policy (2 items, α = .573). The mean total score for all universities was 62.71 (±11.16) on a 100-point scale. CEPS appears to be a valid and reliable tool for assessing college students' perceptions of their health-related campus environment.

The aim of the current study was to study the psychometric properties of the Japanese version of the Social Phobia Inventory (SPIN-J) among Japanese subjects with social anxiety disorder (SAD). The sample consisted of 86 subjects with SAD and 86 controls. Diagnosis was based on a modified version of the Structured Clinical Interview for the DSM-IV. In addition to the SPIN-J, clinician-administered and self-rating scales, including the Japanese versions of the Liebowitz Social Anxiety Scale, the Social Phobia Scale, and the Social Interaction Anxiety Scale, were used. The SPIN-J showed adequate internal consistency (0.82-0.96) for the total and subscales. Correlations between the SPIN-J and the Liebowitz Social Anxiety Scale, the Social Phobia Scale, and the Social Interaction Anxiety Scale ranged from 0.83 to 0.89 and indicated adequate concurrent validity. A cut-off point of 22 between subjects with SAD and controls showed a sensitivity of 96.5% and specificity of 87.2%, indicating robust discriminant validity. The SPIN-J showed adequate reliability and validity for use as a screening tool for social anxiety disorder in Japanese clinical settings. © 2013 The Authors.

2012-06-01

The aim of this study was to construct and validate a short self-rating questionnaire for the assessment of ego functions and ability of self regulation. An item pool of 120 items covering 6 postulated dimensions was reduced by two steps in independent samples (n = 136 + 470) via factor and item analyses to the final version consisting of 35 items. The 5 resulting questionnaire scales "interpersonal disturbances", "frustration tolerance and impulse control", "identity disturbances", "affect differentiation and affect tolerance" and "self-esteem" were well interpretable and showed in confirmatory factor analysis the best fit to the data (CHI²/df = 3.48; RMSEA = 0.73). Total scores were found to differentiate well between diagnostic groups of patients with more or less ego pathology (FANOVA = 9.8; df = 11; p < 0.001), thus proving good concurrent validity. Reliability was shown by testing internal consistency and test-retest correlations. The "Hannover self-regulation questionnaire" (HSRQ) evidently is an appropriate and reliable screening instrument in order to assess ego functions and capacities of self regulation in an economic and user-friendly means. The scale structure allows differentiated diagnostics of weak vs. stable ego functions and may be used for detailed therapy planning. © Georg Thieme Verlag KG Stuttgart · New York.

Several instruments evaluate patient-reported outcomes in diabetes mellitus (DM), but almost none are validated for use in Arabic language. The aim of this study is to test the psychometric properties and responsiveness of the Arabic version of the Diabetes Treatment Satisfaction Questionnaire (DTSQs) in Qatar. Ambulatory Arabic speaking DM patients were interviewed at two consecutive time points in Doha, Qatar. The 8-item DTSQs was administered in conjunction with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the World Health Organization Quality of Life Measure (WHOQOL-Bref) to assess convergent validity. Reliability was evaluated by internal consistency and item analysis. Construct validity was evaluated using "known groups" comparisons (including gender, insulin use, and HbA1c). Sensitivity of DTSQs scores to the subject's metabolic conditions was determined. One hundred subjects (mean age 50.7) participated. Half (54%) were female. The majority (93%) had Type 2 DM, but 39 (42%) were using insulin. Results revealed satisfactory internal consistency. Metabolic measures (fasting blood glucose and AIC) had significant inverse correlations with DTSQs scores (interview 1, Pearson's r=-0.333 and r=-0.401, respectively, p<0.01). Scale criterion and construct validity were found to be satisfactory. Most sub-dimensions of the SF-36 and WHOQOL-Bref were correlated with the DTSQ, indicating a good concurrent validity. As in prior studies, women demonstrated poorer treatment satisfaction. The Qatar Arabic DTSQs version was found to be a reliable and valid instrument for the assessment of treatment satisfaction in Arabic diabetes mellitus patients in the country.

Objective Fear of eye gaze and avoidance of eye contact are core features of social anxiety disorders (SAD). To measure self-reported fear and avoidance of eye gaze, the Gaze Anxiety Rating Scale (GARS) has been developed and validated in recent years in its English version. The main objectives of the present study were to psychometrically evaluate the German translation of the GARS concerning its reliability, factorial structure, and validity. Methods Three samples of participants were enrolled in the study. (1) A non-patient sample (n = 353) completed the GARS and a set of trait questionnaires to assess internal consistency, test-retest reliability, factorial structure, and concurrent and divergent validity. (2) A sample of patients with SAD (n = 33) was compared to a healthy control group (n = 30) regarding their scores on the GARS and the trait measures. Results The German GARS fear and avoidance scales exhibited excellent internal consistency and high stability over 2 and 4 months, as did the original version. The English version’s factorial structure was replicated, yielding two categories of situations: (1) everyday situations and (2) situations involving high evaluative threat. GARS fear and avoidance displayed convergent validity with trait measures of social anxiety and were markedly higher in patients with GSAD than in healthy controls. Fear and avoidance of eye contact in situations involving high levels of evaluative threat related more closely to social anxiety than to gaze anxiety in everyday situations. Conclusions The German version of the GARS has demonstrated reliability and validity similar to the original version, and is thus well suited to capture fear and avoidance of eye contact in different social situations as a valid self-report measure of social anxiety and related disorders in the social domain for use in both clinical practice and research.

The Australian Whiplash Disability Questionnaire (WDQ) was cross-culturally translated, adapted, and tested for validity to be used in German-speaking patients. The self-administered questionnaire evaluates actual pain intensity, problems in personal care, role performance, sleep disturbances, tiredness, social and leisure activities, emotional and concentration impairments with 13 questions rated on an 11-point rating scale from zero to ten. In a first part, the Australian-based WDQ was forward and backward translated. In a consensus conference with all translators and health care professionals, who were experts in the treatment of patients with a whiplash associated disorder (WAD), formulations were refined. Original authors were contacted for clarification and approval of the forward-backward translated version. The German version (WDQ-G) was evaluated for comprehensiveness and clarity in a pre-study patient survey by a random sample of German-speaking patients after WAD and four healthy twelve to thirteen year old teenagers. In a second part, the WDQ-G was evaluated in a patient validation study including patients affected by a WAD. Inpatients had to complete the WDQ-G, the North American Spine Society questionnaire (NASS cervical pain), and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) at entry in the rehabilitation centre. In the pre-study patient survey (response rate 31%) patients rated clarity for title 9.6 ± 0.9, instruction 9.3 ± 1.4 and questions 9.6 ± 0.7, and comprehensiveness for title 9.6 ± 0.7, instruction 9.3 ± 1.4 and questions 9.8 ± 0.4. Time needed to fill in was 13.7 ± 9.0 minutes. In total, 70 patients (47 females, age = 43.4 ± 12.5 years, time since injury: 1.5 ± 2.6 years) were included in the validation study. WDQ-G total score was 74.0 ± 21.3 points (range between 15 and 117 points). Time needed to fill in was 6.7 ± 3.4 minutes with data from 22 patients. Internal consistency was confirmed with Cronbachs's α = 0.89. Concurrent validity showed a highly significant correlation with subscale pain and disability (NASS) at r = 0.74 and subscale pain (SF-36) at r = 0.71. The officially translated and adapted WDQ-G can be used in German-speaking patients affected by a WAD to evaluate patients' impairments in different domains. The WDQ-G is a self-administered outcome measure showing a high internal consistency and good concurrent validity.

Objectives To determine the feasibility, concurrent validity and discriminatory power of the instrument for Identification of Parents At Risk for child Abuse and Neglect (IPARAN) among Dutch parents with a newborn child. Setting Community paediatrics. Participants Data from a controlled trial were used. In total, 2659 Dutch parents with a newborn child were invited to participate. Of the 2659 parents, 759 parents filled in the consent form and participated in the study. Primary and secondary outcome measures Concurrent validity was determined by calculating correlations—using the Pearson’s correlation (r)—between the IPARAN score and related constructs from the following instruments: the Empowerment Questionnaire 2.0, the Family Functioning Questionnaire and the Parenting Stress Questionnaire. Discriminatory power was determined by calculating receiver operating characteristic (ROC) curves between high-risk mothers and low-risk mothers according to their scores on the related constructs. Feasibility was determined by examining the percentage of missing answers. Results In terms of concurrent validity, we found that 3 out of 12 correlations between the IPARAN score and related constructs were strong (ie, r>0.50) and 4 out of 12 were medium (ie, r=0.30–0.49). In terms of discriminatory power, mothers with a score in the borderline/clinical range or lowest 10 percent (P10) range of the related constructs (high-risk mothers) had a higher IPARAN score than mothers with a score in the normal range or highest 90 percent (P90) range of the related constructs (low-risk mothers). Effect sizes varied from d=0.37 to d=1.93, and the area under the ROC curve varied from 0.62 to 0.93. Regarding feasibility, the part of the IPARAN filled in by the mother had on average 0.7% missing answers, whereas the part of the IPARAN filled in by the father had on average 1.7% missing answers. Conclusion The results of this study support the concurrent validity, discriminatory power and feasibility of the IPARAN among a population of Dutch parents with a newborn child. PMID:28838892

Social exclusion can be both a cause and a consequence of mental health problems. Socially inclusive practice by mental health professionals can mitigate against the stigmatizing and excluding effects of severe mental illness. To develop and test the validity of a measure of social inclusion for individuals with severe mental illness - the Social Inclusion Questionnaire User Experience (SInQUE). The domains of the SInQUE were chosen to reflect the domains of social inclusion identified in the Poverty and Social Exclusion Survey. Patients with severe mental illness were recruited from rehabilitation, general and forensic psychiatric services and were asked to complete the questionnaire in an individual interview with a researcher. Sixty six patients with schizophrenia and schizoaffective disorder completed the SInQUE, alongside measures of psychiatric symptoms, needs and quality of life, to assess its acceptability, and concurrent and construct (convergent and discriminant) validity. The SInQUE took 45 minutes to complete and was found to have good concurrent and discriminant validity. Convergent validity was established for two domains: social integration and productivity. Preliminary findings suggest that the SInQUE may be a useful tool for assessing and monitoring social inclusion in individuals with severe mental illness. It has construct and concurrent validity with measures of unmet need and quality of life in this group. Further testing of the reliability of the SInQUE on a larger population is indicated.

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.

Purpose/Aim: This purpose of this study was to investigate the reliability, minimal detectable change (MDC), and concurrent validity of active spinal mobility measurements using a gravity‐based bubble inclinometer and iPhone® application. Materials/Methods: Two investigators each used a bubble inclinometer and an iPhone® with inclinometer application to measure total thoracolumbo‐pelvic flexion, isolated lumbar flexion, total thoracolumbo‐pelvic extension, and thoracolumbar lateral flexion in 30 asymptomatic participants using a blinded repeated measures design. Results: The procedures used in this investigation for measuring spinal mobility yielded good intrarater and interrater reliability with Intraclass Correlation Coefficients (ICC) for bubble inclinometry ≥ 0.81 and the iPhone® ≥ 0.80. The MDC90 for the interrater analysis ranged from 4° to 9°. The concurrent validity between bubble inclinometry and the iPhone® application was good with ICC values of ≥ 0.86. The 95% level of agreement indicates that although these measuring instruments are equivalent individual differences of up to 18° may exist when using these devices interchangeably. Conclusions: The bubble inclinometer and iPhone® possess good intrarater and interrater reliability as well as concurrent validity when strict measurement procedures are adhered to. This study provides preliminary evidence to suggest that smart phone applications may offer clinical utility comparable to inclinometry for quantifying spinal mobility. Clinicians should be aware of the potential disagreement when using these devices interchangeably. Level of Evidence: 2b (Observational study of reliability) PMID:23593551

To investigate the reliability, minimal detectable change (MDC90) and concurrent validity of a gravity-based bubble inclinometer (inclinometer) and iPhone® application for measuring standing lumbar lordosis. Two investigators used both an inclinometer and an iPhone® with an inclinometer application to measure lumbar lordosis of 30 asymptomatic participants. ICC models 3,k and 2,k were used for the intrarater and interrater analysis, respectively. Good interrater and intrarater reliability was present for the inclinometer with Intraclass Correlation Coefficients (ICC) of 0.90 and 0.85, respectively and the iPhone® application with ICC values of 0.96 and 0.81. The minimal detectable change (MDC90) indicates that a change greater than or equal to 7° and 6° is needed to exceed the threshold of error using the iPhone® and inclinometer, respectively. The concurrent validity between the two instruments was good with a Pearson product-moment coefficient of correlation (r) of 0.86 for both raters. Ninety-five percent limits of agreement identified differences ranging from 9° greater in regards to the iPhone® to 8° less regarding the inclinometer. Both the inclinometer and iPhone® application possess good interrater reliability, intrarater reliability and concurrent validity for measuring standing lumbar lordosis. This investigation provides preliminary evidence to suggest that smart phone applications may offer clinical utility comparable to inclinometry for quantifying standing lumbar lordosis. Clinicians should recognize potential individual differences when using these devices interchangeably.

Attention deficit hyperactivity disorder (ADHD) is a common neuropsychiatric disorder in adulthood. Its diagnosis requires a retrospective evaluation of ADHD symptoms in childhood, the continuity of these symptoms in adulthood, and a differential diagnosis. For these reasons, diagnosis of ADHD in adults is a complex process which needs effective diagnostic tools. To analyse the criterion validity of the CAADID semi-structured interview, Spanish version, and the concurrent validity compared with other ADHD severity scales. An observational case-control study was conducted on 691 patients with ADHD. They were out-patients treated in a program for adults with ADHD in a hospital. A sensitivity of 98.86%, specificity 67.68%, positive predictive value 90.77% and a negative predictive value 94.87% were observed. Diagnostic precision was 91.46%. The kappa index concordance between the clinical diagnostic interview and the CAADID was 0.88. Good concurrent validity was obtained, the CAADID correlated significantly with WURS scale (r=0.522, P<.01), ADHD Rating Scale (r=0.670, P<.0.1) and CAARS (self-rating version; r=0.656, P<.01 and observer-report r=0.514, P<.01). CAADID is a valid and useful tool for the diagnosis of ADHD in adults for clinical, as well as for research purposes. Copyright © 2012 SEP y SEPB. Published by Elsevier España, S.L.

This study examines a potential instrument for measurement of typing postures of children. This paper describes inter-rater, test-retest reliability and concurrent validity of the Keyboard Personal Computer Style instrument (K-PeCS), an observational measurement of postures and movements during keyboarding, for use with children. Two trained raters independently rated videos of 24 children (aged 7-10 years). Six children returned one week later for identifying test-retest reliability. Concurrent validity was assessed by comparing ratings obtained using the K-PECS to scores from a 3D motion analysis system. Inter-rater reliability was moderate to high for 12 out of 16 items (Kappa: 0.46 to 1.00; correlation coefficients: 0.77-0.95) and test-retest reliability varied across items (Kappa: 0.25 to 0.67; correlation coefficients: r = 0.20 to r = 0.95). Concurrent validity compared favourably across arm pathlength, wrist extension and ulnar deviation. In light of the limitations of other tools the K-PeCS offers a fairly affordable, reliable and valid instrument to address the gap for measurement of typing styles of children, despite the shortcomings of some items. However further research is required to refine the instrument for use in evaluating typing among children. Copyright © 2012 Elsevier Ltd and The Ergonomics Society. All rights reserved.

Evaluation of mental health services based on patients' needs assessments has never taken place in Greece, although it is a crucial factor for the efficient use of their limited resources. To examine the inter-rater and test-retest reliability and the concurrent/convergent validity of the Greek research version of the Camberwell Assessment of Need-Research (CAN-R). A total of 53 schizophrenic patient-staff pairs were interviewed twice to test the inter-rater and test-retest reliability of the Greek version of the CAN-R. The World Health Organization Quality of Life-Brief Form (WHOQOL-BREF) and World Health Organization Disability Assessment Schedule-2.0 (WHODAS-2.0) were administered to the patients to examine concurrent validity. The inter-rater and test-retest reliability of patient and staff interviews for the 22 individual items and the eight summary scores of the instrument's four sections were good to excellent. Significant correlations emerged between CAN scores and the WHOQOL-BREF and WHODAS-2.0 domains for both patient and staff ratings, indicating good concurrent validity. Our results suggest that the Greek version of the CAN-R is a reliable instrument for assessing mental health patients' needs. Moreover, it is the first CAN-R validity study with satisfactory results using WHOQOL-BREF and WHODAS-2.0 as criterion variables. © The Author(s) 2013.

Background Surgeries employing arthroscopic techniques are among the most commonly performed in orthopaedic clinical practice however, valid and reliable methods of assessing the arthroscopic skill of orthopaedic surgeons are lacking. Hypothesis The Arthroscopic Surgery Skill Evaluation Tool (ASSET) will demonstrate content validity, concurrent criterion-oriented validity, and reliability, when used to assess the technical ability of surgeons performing diagnostic knee arthroscopy on cadaveric specimens. Study Design Cross-sectional study; Level of evidence, 3 Methods Content validity was determined by a group of seven experts using a Delphi process. Intra-articular performance of a right and left diagnostic knee arthroscopy was recorded for twenty-eight residents and two sports medicine fellowship trained attending surgeons. Subject performance was assessed by two blinded raters using the ASSET. Concurrent criterion-oriented validity, inter-rater reliability, and test-retest reliability were evaluated. Results Content validity: The content development group identified 8 arthroscopic skill domains to evaluate using the ASSET. Concurrent criterion-oriented validity: Significant differences in total ASSET score (p<0.05) between novice, intermediate, and advanced experience groups were identified. Inter-rater reliability: The ASSET scores assigned by each rater were strongly correlated (r=0.91, p <0.01) and the intra-class correlation coefficient between raters for the total ASSET score was 0.90. Test-retest reliability: there was a significant correlation between ASSET scores for both procedures attempted by each individual (r = 0.79, p<0.01). Conclusion The ASSET appears to be a useful, valid, and reliable method for assessing surgeon performance of diagnostic knee arthroscopy in cadaveric specimens. Studies are ongoing to determine its generalizability to other procedures as well as to the live OR and other simulated environments. PMID:23548808

Concurrent validity of scores for the Alberta Infant Motor Scale (AIMS) and the Peabody Developmental Gross Motor Scale-2 (PDGMS-2) was examined with a sample of 35 infants at dual risk for motor delays or disabilities. Dual risk was defined as low birthweight ( 9 months of age. Novice examiners' scores on both measures closely approximated those of experienced examiners (ICC range = .98 to .99). The results support concurrent validity of the AIMS and PDGMS-2 for infants at dual risk and have implications for using the AIMS in high-risk follow-up programs, particularly in relation to evaluating functional components of motor performance and ease of administration.

Leprosy is endemic in many countries and results in activity limitations. There is a need for assessment tools to guide professionals in their evaluation and choice of intervention in order to improve conditions for leprosy-affected people. The purpose of our study was to evaluate the concurrent validity of the Amharic version of Screening of Activity Limitation and Safety Awareness (SALSA-am) scale with Amharic version of Disability of the Arm, Shoulder and Hand (DASH-am) questionnaire. Thirty-eight individuals with nerve damage due to leprosy completed the SALSA-am and DASH-am questionnaires. Spearman's rank correlation was used to determine relationships between SALSA and DASH scores. Specificity, sensitivity and accuracy were calculated. There was a good correlation 0.87 (P < 0.001) between SALSA-am and DASH-am scores. Sensitivity, specificity and accuracy were calculated with acceptable results. SALSA-am is considered a useful questionnaire for determining activity limitations in persons affected by leprosy, and showed good correlation with DASH-am. The concurrent validity was considered good.

Introduction: An international clinical trial enrolled 174 ambulatory males ≥5 years old with nonsense mutation Duchenne muscular dystrophy (nmDMD). Pretreatment data provide insight into reliability, concurrent validity, and minimal clinically important differences (MCIDs) of the 6-minute walk test (6MWT) and other endpoints. Methods: Screening and baseline evaluations included the 6-minute walk distance (6MWD), timed function tests (TFTs), quantitative strength by myometry, the PedsQL, heart rate–determined energy expenditure index, and other exploratory endpoints. Results: The 6MWT proved feasible and reliable in a multicenter context. Concurrent validity with other endpoints was excellent. The MCID for 6MWD was 28.5 and 31.7 meters based on 2 statistical distribution methods. Conclusions: The ratio of MCID to baseline mean is lower for 6MWD than for other endpoints. The 6MWD is an optimal primary endpoint for Duchenne muscular dystrophy (DMD) clinical trials that are focused therapeutically on preservation of ambulation and slowing of disease progression.

The aim of this study was to assess the concurrent validity and reliability of the Simple Goniometer (SG) iPhone® app compared to the Universal Goniometer (UG). Within subject comparison design comparing the UG with the SG app. James Cook University, Townsville, Queensland, Australia. Thirty-six volunteer participants, with a mean age of 60.6 years (SD 6.2). Not applicable. Thirty-six participants performed three standing lunges during which the knee joint angle was measured with the SG app and the UG. There were no significant differences in the measures of individual knee joint angles between the UG and the SG app. Pearson correlations of 0.96-0.98 and intraclass correlation coefficients of 0.97-0.99 (95% confidence interval: 0.95-1.00) were recorded for all measures. Using the Bland-Altman method, the standard error of the mean of the differences and the standard deviation of the mean of the differences were low. The measurements from the SG iPhone® app were reliable and possessed concurrent validity for this sample and protocol when compared to the UG.

Fellows in pulmonary and critical care medicine are required to show competency in facilitating family meetings for critically ill patients. There are many assessment measures available for evaluating physician-patient communication (e.g., the SEGUE Framework [Set the stage, Elicit information, Give information, Understand the patient's perspective, End the encounter]) and some designed for family meetings. However, no validated measure exists that is specifically designed to assess communication skills during family meetings with surrogate decision makers in intensive care settings. We developed the Family Meeting Behavioral Skills Checklist (FMBSC) to measure advanced communication skills of fellows in family meetings of critically ill patients based on a literature review and consensus of an interdisciplinary group of communications experts. We evaluated the psychometric properties of the FMBSC. We digitally recorded 16 pulmonary/critical care fellows performing a simulated family meeting for a critically ill patient at the end of 1 year of fellowship training. Two clinical health psychologists evaluated each recording independently using the FMBSC Rating Scale and the SEGUE Framework. Judges recorded the number of skills performed using the checklist and employed a summary rating scale to judge the level of performance for each of nine subsets of skills. Each instrument was scored and converted to percentage scores. The FMBSC and SEGUE Framework items were summed and converted to percentage scores for each category and as a total for each instrument. The rating scale items on the FMBSC were also summed and converted to a percentage score. Four primary analyses were conducted to evaluate interjudge reliability, internal consistency, and concurrent validity. Interrater reliability was higher for the FMBSC (intraclass correlation [ICC2,2] = 0.57) than for the SEGUE instrument (ICC2,2 = 0.32) or the FMBSC Rating Scale (ICC2,2 = 0.23). The FMBSC demonstrated evidence of concurrent validity through high positive correlations with both the FMBSC Rating Scale and the SEGUE instrument (r = +0.83, P ≤ 0.01; r = +0.65, P ≤ 0.01 respectively). All but one of the nine subscales on the FMBSC showed adequate internal consistency (reliabilities ranged from 0.18 to 0.68). Interjudge reliability was higher for the FMBSC (ICC2,2 = 0.57) than for the SEGUE instrument (ICC2,2 = 0.32) or the FMBSC Rating Scale (ICC2,2 = 0.23). The FMBSC demonstrated internal consistency and structural validity in assessing advanced communication skills of fellows in facilitating family meetings of critically ill patients in the ICU. Interjudge reliability was better for the FMBS Checklist than it was for the other measures.

The Center for Epidemiological Studies Depression Scale (CES-D) is designed to measure the current level of depressive symptomatology in the general population. However, no review has examined whether the scale is reliable and valid among children and adolescents in Korea. The purpose of this study was to test whether the Korean form of the CES-D is valid in adolescents. Data were obtained from 1,884 adolescents attending grades 1-3 in Korean middle schools. Reliability was evaluated by internal consistency (Cronbach's alpha). Concurrent validity was evaluated by a correlation analysis between the CES-D and other scales. Construct validity was evaluated by exploratory factor and confirmatory factor analyses. The internal consistency coefficient for the entire group was 0.88. The CES-D was positively correlated with scales that measure negative psychological constructs, such as the State Anxiety Inventory for Children, the Korean Social Anxiety Scale for Children and Adolescents, and the Reynold Suicidal Ideation Questionnaire, but it was negatively correlated with scales that measure positive psychological constructs, such as the Korean version of the Rosenberg Self-Esteem Scale and the Connor-Davidson Resilience Scale-2. The CES-D was examined by three-dimensional exploratory factor analysis, and the three-factor structure of the scale explained 53.165% of the total variance. The variance explained by factor I was 24.836%, that explained by factor II was 15.988%, and that explained by factor III was 12.341%. The construct validity of the CES-D was tested by confirmatory factor analysis, and we applied the entire group's data using a three-factor hierarchical model. The fit index showed a level similar to those of other countries' adolescent samples. The CES-D has high internal consistency and addresses psychological constructs similar to those addressed by other scales. The CES-D showed a three-factor structure in an exploratory factor analysis. The present findings suggest that the CES-D is a useful and reliable tool for measuring depression in Korean adolescents.

The Acoustic Voice Quality Index (AVQI) is an objective method to quantify the severity of overall voice quality in concatenated continuous speech and sustained phonation segments. Recently, AVQI was successfully modified to be more representative and ecologically valid because the internal consistency of AVQI was balanced out through equal proportion of the 2 speech types. The present investigation aims to explore its external validation in a large data set. An expert panel of 12 speech-language therapists rated the voice quality of 1058 concatenated voice samples varying from normophonia to severe dysphonia. The Spearman rank-order correlation coefficients (r) were used to measure concurrent validity. The AVQI's diagnostic accuracy was evaluated with several estimates of its receiver operating characteristics (ROC). Finally, 8 of the 12 experts were chosen because of reliability criteria. A strong correlation was identified between AVQI and auditoryperceptual rating (r = 0.815, P = .000). It indicated that 66.4% of the auditory-perceptual rating's variation was explained by AVQI. Additionally, the ROC results showed again the best diagnostic outcome at a threshold of AVQI = 2.43. This study highlights external validation and diagnostic precision of the AVQI version 03.01 as a robust and ecologically valid measurement to objectify voice quality. © The Author(s) 2016.

Assess validity of the ecSatter Inventory (ecSI) to measure eating competence (EC). Concurrent administration of ecSI with validated measures of eating behaviors using on-line and paper-pencil formats. The on-line survey was completed by 370 participants; 462 completed the paper version. Participants included 863 adults with 832 usable surveys from respondents (mean age 36.2 +/- 13.4 years) without eating disorders, mostly female, white, educated, overweight, physically active, and food secure. Of those indicating intent to complete the on-line survey, 80.3% did so; 54% of mailed surveys were returned. Eating and food behaviors compared among EC tertiles and between dichotomous EC categories; internal consistency of ecSI. Analysis of variance, independent t tests, chi-square, factor analysis, logistic regression. Significance level was P < .05. Mean ecSI score was 31.1 +/- 7.5. ecSI included 4 subscales with internal reliability and content validity. Construct validity was supported by specific behavioral profiles for ecSI tertiles and ecSI dichotomized categories. Persons unsatisfied with weight were 54% less likely to be EC; unit increase in the food like index was associated with nearly 3 times greater likelihood of being EC. The ecSatter Inventory is a valid measure of EC and can be used for descriptive and outcome measurements.

Cognitive impairment represents a common mental health problem in community-dwelling and institutionalized older adults, and the prevalence increases with age. Multidisciplinary teams are often asked to assess cognitive and functional impairment in this population. The Cognitive Assessment of Minnesota was created by occupational therapists for this purpose and is frequently used, but has not been extensively validated. This study examined the performance of the CAM and compared it to the MMSE with 113 outpatient clinic patients over the age of 60. Subgroups were established based on scores on a depression inventory to determine if the presence of depressed mood altered the relationship between the measures. Both measures demonstrated good internal consistency. The overall correlation between the two measures was high, statistically significant and remained high regardless of depression status. We offer recommendations about the utility of each measure in screening cognitive functioning for older adults. PMID:21584250

The social interaction anxiety scale (SIAS) and the social phobia scale (SPS) assess anxiety in social interactions and fear of scrutiny by others. This study examines the psychometric properties of the Dutch versions of the SIAS and SPS using data from a large group of patients with social phobia and a community-based sample. Confirmatory factor analysis revealed that the SIAS is unidimensional, whereas the SPS is comprised of three subscales. The internal consistency of the scales and subscales was good. The concurrent and discriminant validity was supported and the scales were well able to discriminate between patients and community-based respondents. Cut-off values with excellent sensitivity and specificity are presented. Of all self-report measures included, the SPS was the most sensitive for treatment effects. Normative data are provided which can be used to assess whether clinically significant change has occurred in individual patients. PMID:24701560

This study examined the psychometric properties of the Connor-Davidson Resilience Scale (CD-RISC) with a Chinese military population with the aim of finding a suitable instrument to quantify resilience in Chinese military service members. The confirmatory factor analysis results did not support the factorial structure of the original or the Chinese community version of the CD-RISC, but the exploratory factor analysis results revealed a three-factor model (composed of Competency, Toughness, and Adaptability) that seemed to fit. Moreover, the repeat confirmatory factory analysis replicated the three-factor model. Additionally, the CD-RISC with a Chinese military sample exhibited appropriate psychometric properties, including internal consistency, test-retest reliability, and structural and concurrent validity. The revised CD-RISC with a Chinese military sample provides insight into the resilience measurement framework and could be a reliable and valid measurement for evaluating resilience in a Chinese military population.

  Spinal axial rotation is required for many functional and sporting activities. Eighty percent of axial rotation occurs in the thoracic spine. Existing measures of thoracic spine rotation commonly involve laboratory equipment, use a seated position, and include lumbar motion. A simple performance-based outcome measure would allow clinicians to evaluate isolated thoracic spine rotation. Currently, no valid measure exists.   To explore the criterion and concurrent validity of a digital inclinometer (DI) and iPhone Clinometer app (iPhone) for measuring thoracic spine rotation using the heel-sit position.   Controlled laboratory study.   University laboratory.   A total of 23 asymptomatic healthy participants (14 men, 9 women; age = 25.82 ± 4.28 years, height = 170.26 ± 8.01 cm, mass = 67.50 ± 9.46 kg, body mass index = 23.26 ± 2.79) were recruited from a student population.   We took DI and iPhone measurements of thoracic spine rotation in the heel-sit position concurrently with dual-motion analysis (laboratory measure) and ultrasound imaging of the underlying bony tissue motion (reference standard). To determine the criterion and concurrent validity, we used the Pearson product moment correlation coefficient (r, 2 tailed) and Bland-Altman plots.   The DI (r = 0.88, P < .001) and iPhone (r = 0.88, P < .001) demonstrated strong criterion validity. Both also had strong concurrent validity (r = 0.98, P < .001). Bland-Altman plots illustrated mean differences of 5.82° (95% confidence interval [CI] = 20.37°, -8.73°) and 4.94° (95% CI = 19.23°, -9.35°) between the DI and iPhone, respectively, and the reference standard and 0.87° (95% CI = 6.79°, -5.05°) between the DI and iPhone.   The DI and iPhone provided valid measures of thoracic spine rotation in the heel-sit position. Both can be used in clinical practice to assess thoracic spine rotation, which may be valuable when evaluating thoracic dysfunction.

The effectiveness of the swimming turn is highly influential to overall performance in competitive swimming. The push-off or wall contact, within the turn phase, is directly involved in determining the speed the swimmer leaves the wall. Therefore, it is paramount to develop reliable methods to measure the wall-contact-time during the turn phase for training and research purposes. The aim of this study was to determine the concurrent validity and reliability of the Pool Pad App to measure wall-contact-time during the freestyle and backstroke tumble turn. The wall-contact-times of nine elite and sub-elite participants were recorded during their regular training sessions. Concurrent validity statistics included the standardised typical error estimate, linear analysis and effect sizes while the intraclass correlating coefficient (ICC) was used for the reliability statistics. The standardised typical error estimate resulted in a moderate Cohen's d effect size with an R 2 value of 0.80 and the ICC between the Pool Pad and 2D video footage was 0.89. Despite these measurement differences, the results from this concurrent validity and reliability analyses demonstrated that the Pool Pad is suitable for measuring wall-contact-time during the freestyle and backstroke tumble turn within a training environment.

2012-01-01

Background Evidence of auditory-guided speech development can be heard as the prelinguistic vocalizations of young cochlear implant recipients become increasingly complex, phonetically diverse, and speech-like. In research settings, these changes are most often documented by collecting and analyzing speech samples. Sampling, however, may be too time-consuming and impractical for widespread use in clinical settings. The Conditioned Assessment of Speech Production (CASP; Ertmer & Stoel-Gammon, 2008) is an easily administered and time-efficient alternative to speech sample analysis. The current investigation examined the concurrent validity of the CASP and data obtained from speech samples recorded at the same intervals. Methods Nineteen deaf children who received CIs before their third birthdays participated in the study. Speech samples and CASP scores were gathered at 6, 12, 18, and 24 months post-activation. Correlation analyses were conducted to assess the concurrent validity of CASP scores and data from samples. Results CASP scores showed strong concurrent validity with scores from speech samples gathered across all recording sessions (6 – 24 months). Conclusions The CASP was found to be a valid, reliable, and time-efficient tool for assessing progress in vocal development during young CI recipient’s first 2 years of device experience.

Measuring coherence with entanglement concurrence

Quantum coherence is a fundamental manifestation of the quantum superposition principle. Recently, Baumgratz et al (2014 Phys. Rev. Lett. 113 140401) presented a rigorous framework to quantify coherence from the view of theory of physical resource. Here we propose a new valid quantum coherence measure which is a convex roof measure, for a quantum system of arbitrary dimension, essentially using the generalized Gell-Mann matrices. Rigorous proof shows that the proposed coherence measure, coherence concurrence, fulfills all the requirements dictated by the resource theory of quantum coherence measures. Moreover, strong links between the resource frameworks of coherence concurrence and entanglement concurrence is derived, which shows that any degree of coherence with respect to some reference basis can be converted to entanglement via incoherent operations. Our work provides a clear quantitative and operational connection between coherence and entanglement based on two kinds of concurrence. This new coherence measure, coherence concurrence, may also be beneficial to the study of quantum coherence.

The 30-item USDI is a self-report measure that assesses depressive symptoms among university students. It consists of three correlated three factors: lethargy, cognitive-emotional and academic motivation. The current research used confirmatory factor analysis to asses construct validity and determine whether the original factor structure would be replicated in a different sample. Psychometric properties were also examined. Participants were 1148 students (mean age 22.84 years, SD=6.85) across all faculties from a large Australian metropolitan university. Students completed a questionnaire comprising of the USDI, the depression anxiety stress scale (DASS) and Life Satisfaction Scale (LSS). The three correlated factor model was shown to be an acceptable fit to the data, indicating sound construct validity. Internal consistency of the scale was also demonstrated to be sound, with high Cronbach alpha values. Temporal stability of the scale was also shown to be strong through test-retest analysis. Finally, concurrent and discriminant validity was examined with correlations between the USDI and DASS subscales as well as the LSS, with sound results further supporting the construct validity of the scale. Cut-off points were also developed to aid total score interpretation. Response rates are unclear. In addition, the representativeness of the sample could be improved potentially through targeted recruitment (i.e. reviewing the online sample statistics during data collection, examining the representativeness trends and addressing particular faculties within the university that were underrepresented). The USDI provides a valid and reliable method of assessing depressive symptoms found among university students. © 2013 Elsevier B.V. All rights reserved.

Objective: Despite the fact that the mobile phone has become a pervasive technology of our time, little research has been done on mobile dependency. Therefore, a valid and reliable instrument, conforming to Iranian culture seems essential. The aim of our study was to validate the Iranian version of MPPUS (Mobile Phone Problematic Use Scale). Methods: This was a cross-sectional research, in which data were collected from 600 students studying at Tehran universities. Stratified sampling method was used to collect data. All participants completed Demographic Questionnaire, Cellular Phone Dependency Questionnaire (CPDQ) anonymously. Finally, a clinical interview (based on DSM-IV-TR) was conducted with 100 participants. Data were analyzed using concurrent validity, factor analysis, internal consistency (Cronbach’s’α), split half, test-retest and ROC Curve by SPSS18 Software. Results: As a result of reliability analysis and factor analysis by principal component and Varimax rotation, we extracted three factors including preoccupation, withdrawal symptoms and overuse of mobile phones in both males and females. Internal consistency (Cronbach’s alpha) of the MPPUS was .91; Cronbach’s alpha of the factors was .87, .70, .82 respectively. The test-retest correlation of the MPPUS was .56. The best cut off point for this questionnaire (MPPUS) was 160. Conclusion: The MPPUS proved to be a reliable questionnaire with adequate factor models to assess the extent of problems caused by the “misuse” of mobile phones in the Iranian society; however, further studies are needed on this topic.

Accurate and efficient developmental screening measures are critical for early identification of developmental problems; however, few reliable and valid tests are available in Korea as well as other countries outside the USA. The Ages and Stages Questionnaires (ASQ) was chosen for study with young children in Korea. The ASQ was translated into Korean and necessary cross-cultural adaptations were made. The translated version was then distributed and completed by 3220 parents of young children between the ages of 4 months and 5 years. Reliability was studied including domain correlations, internal consistency, and performance of identification cut-off scores for the Korean population. Rasch analyses including tests of Differential Item Functioning, contrasting Korean and US samples were also performed. In general, internal consistency of the Korean ASQ was high, with overall correlations 0.75 for communication, 0.85 for gross motor, 0.74 for fine motor, 0.72 for problem solving, and 0.65 for personal-social. Validity, including concurrent validity, also had strong evidence. Mean scores of children on the Korean translation of the ASQ and the US normative sample were generally similar. Rasch analyses indicated the majority of items functioned similarly across the Korean sample. In general, the ASQ was translated with cultural appropriateness in mind and functioned as a valid and reliable parent-completed screening test to assist in early identification of young children with developmental delays. Further research is needed to confirm these results with a larger and more diverse Korean sample.

The most commonly used instrument for measuring anger is the State-Trait Anger Expression Inventory-2 (STAXI-2; Spielberger, 1999). This study further examines the validity of the STAXI-2 and compares anger scores between several clinical and nonclinical samples. Reliability, concurrent, and construct validity were investigated in Dutch undergraduate students (N = 764), a general population sample (N = 1211), and psychiatric outpatients (N = 226). The results support the reliability and validity of the STAXI-2. Concurrent validity was strong, with meaningful correlations between the STAXI-2 scales and anger-related constructs in both clinical and nonclinical samples. Importantly, patients showed higher experience and expression of anger than the general population sample. Additionally, forensic outpatients with addiction problems reported higher Anger Expression-Out than general psychiatric outpatients. Our conclusion is that the STAXI-2 is a suitable instrument to measure both the experience and the expression of anger in both general and clinical populations. © 2016 Wiley Periodicals, Inc.

Impaired postural stability places individuals with Parkinson's at an increased risk for falls. Given the high incidence of fall-related injuries within this population, ongoing assessment of postural stability is important. To evaluate the validity of the Nintendo Wii(®) balance board as a measurement tool for the assessment of postural stability in individuals with Parkinson's. Twenty individuals with Parkinson's participated. Subjects completed testing on two balance tasks with eyes open and closed on a Wii(®) balance board and biomechanical force platform. Bland-Altman plots and a two-way, random-effects, single measure intraclass correlation coefficient model were used to assess concurrent validity of centre-of-pressure data. Concurrent validity was demonstrated to be excellent across balance tasks (intraclass correlation coefficients = 0.96, 0.98, 0.92, 0.94). This study suggests that the Wii(®) balance board is a valid tool for the quantification of postural stability among individuals with Parkinson's.

For RPE-color scale validation, 12 Young (M = 21.7 yr., SD = 1.5) and 10 Older (M = 60.3 yr., SD = 3.5) adult women performed a maximal graded exercise test on a treadmill and reported perceived exertion in both RPE-color and RPE-Borg scales. In the Young group, the RPE-color scale was significantly associated with heart rate and oxygen consumption, having strong correlations with the RPE-Borg scale. In the Older group, the RPE-color scale was significantly associated with heart rate, having moderate to high correlations with the RPE-Borg scale. The RPE-color scale demonstrated concurrent and construct validity in the Young women, as well as construct validity in Older adults.

Currently, there is no generally agreed measure available to quantify a subject's perceived severity of exercise-induced leg pain symptoms. The aim of this study was to develop and validate a questionnaire that measures the severity of symptoms that impact on function and sports ability in patients with exercise-induced leg pain. The exercise-induced leg pain questionnaire for German-speaking patients (EILP-G) was developed in five steps: (1) initial item generation, (2) item reduction, (3) pretesting, (4) expert meeting and (5) validation. The resulting EILP-G was tested for reliability, validity and internal consistency in 20 patients with exercise-induced leg pain, 20 asymptomatic track and field athletes serving as a population at risk and 33 asymptomatic sport students. The patient group scored the EILP-G questionnaire significantly lower than both control groups (each p<0.001). Test-retest demonstrates an excellent reliability in all tested groups (Intraclass Correlation Coefficient, ICC=0.861-0.987). Concurrent validity of the EILP-G questionnaire showed a substantial agreement when correlated with the chronic exertional compartment syndrome classification system of Schepsis (r=-0.743; p<0.001). Internal consistency for the EILP-G questionnaire was 0.924. EILP-G questionnaire is a valid and reliable self-administered and disease-related outcome tool to measure the severity of symptoms that impact on function and sports ability in patients with exercise-induced leg pain. It can be recommended as a robust tool for measuring the subjectively perceived severity in German-speaking patients with exercise-induced leg pain. Published by the BMJ Publishing Group Limited.

In the era of intensity-modulated radiotherapy (IMRT), the efficacy of additional neoadjuvant chemotherapy (NACT) to concurrent chemoradiotherapy (CCRT) in locoregionally advanced nasopharyngeal carcinoma (NPC) is currently being investigated in ongoing trials. Overall survival (OS) is the gold standard endpoint in NPC trials. We performed this analysis to identify surrogate endpoints for OS, which could shorten follow-up duration and speed up assessment of treatment effects. We retrospectively analysed 208 matched-pair patients with locoregionally advanced NPC receiving NACT+CCRT or CCRT. Progression-free survival (PFS), failure-free survival (FFS), distant failure-free survival (D-FFS) and locoregional failure-free survival (LR-FFS) at 2 and 3 years were assessed as surrogates for 5-year OS according to Prentice's criteria. The strength of the associations were assessed using Spearman's rank correlation coefficient. No significant differences were observed between treatment arms for any surrogate endpoint at 2 years, which rejected Prentice's second criterion. In contrast, 3-year LR-FFS, PFS, FFS and D-FFS were consistent with all four of Prentice's criteria; the rank correlation coefficient (0.730) between 3-year PFS and 5-year OS was highest. 3-year PFS, FFS and D-FFS could be valid surrogate endpoints for 5-year OS; 3-year PFS may be the most accurate.

The Family Empowerment Scale (FES) is a widely used instrument which measures the parents' own sense of their empowerment at the level of the family, service system and community. It was originally developed for parents of children with emotional disabilities. The aims of this study were to evaluate the validity and reliability of the Finnish FES and to examine its responsiveness in measuring the empowerment of parents with small children. The English FES was translated into Finnish using back translation and modified so as to be generic and convenient for all families. The construct, convergent, discriminant and concurrent validities, reliability and responsiveness of the Finnish FES were examined. Participants (n = 955) were the parents of children aged 0-9 years who had been selected using stratified random sampling. Confirmatory factor analysis proved that the Finnish FES had three subscales based on the original FES. Convergent and discriminant validities confirmed and supported the same construct. The relationship between parents' participation and empowerment was tested for concurrent validity. As in previous FES studies, the participating parents were more empowered, which supported the concurrent validity. The reliability of the Finnish FES proved acceptable for both parents. The Finnish FES could also discriminate the responses of the parents. Participation in the activities organized by the family service system influenced parents' perceptions of empowerment more than did their background characteristics. The Finnish FES is a valid and reliable instrument and it is suitable for measuring the empowerment of parents. However, it is necessary to consider how the FES would identify in the best way the parents who perhaps need some help. © 2013 John Wiley & Sons Ltd.

Traditional “paper-and-pencil” testing is imprecise in measuring speed and hence limited in assessing performance efficiency, but computerized testing permits precision in measuring itemwise response time. We present a method of scoring performance efficiency (combining information from accuracy and speed) at the item level. Using a community sample of 9,498 youths age 8-21, we calculated item-level efficiency scores on four neurocognitive tests, and compared the concurrent, convergent, discriminant, and predictive validity of these scores to simple averaging of standardized speed and accuracy-summed scores. Concurrent validity was measured by the scores' abilities to distinguish men from women and their correlations with age; convergent and discriminant validity were measured by correlations with other scores inside and outside of their neurocognitive domains; predictive validity was measured by correlations with brain volume in regions associated with the specific neurocognitive abilities. Results provide support for the ability of itemwise efficiency scoring to detect signals as strong as those detected by standard efficiency scoring methods. We find no evidence of superior validity of the itemwise scores over traditional scores, but point out several advantages of the former. The itemwise efficiency scoring method shows promise as an alternative to standard efficiency scoring methods, with overall moderate support from tests of four different types of validity. This method allows the use of existing item analysis methods and provides the convenient ability to adjust the overall emphasis of accuracy versus speed in the efficiency score, thus adjusting the scoring to the real-world demands the test is aiming to fulfill.

We evaluated feasibility and benefit of implementing structured learning in a robotics program. Furthermore, we assessed validity of a proficiency assessment tool for stepwise graduation. Teaching cases included robotic radical prostatectomy and partial nephrectomy. Procedure steps were categorized: basic, intermediate, and advanced. An assessment tool ["proficiency score" (PS)] was developed to evaluate ability to safely and autonomously complete a step. Graduation required a passing PS (PS ≥ 3) on three consecutive attempts. PS and validated global evaluative assessment of robotic skills (GEARS) were evaluated for completed steps. Linear regression was utilized to determine postgraduate year/PS relationship (construct validity). Spearman's rank correlation coefficient measured correlation between PS and GEARS evaluations (concurrent validity). Intraclass correlation (ICC) evaluated PS agreement between evaluator classes. Twenty-one robotic trainees participated within the pilot program, completing a median of 14 (2-69) cases each. Twenty-three study evaluators scored 14 (1-60) cases. Over 4 months, 229/294 (78 %) cases were designated "teaching" cases. Residents completed 91 % of possible evaluations; faculty completed 78 %. Verbal and quantitative feedback received by trainees increased significantly (p = 0.002, p < 0.001, respectively). Average PS increased with PGY (post-graduate year) for basic and intermediate steps (regression slopes: 0.402 (p < 0.0001), 0.323 (p < 0.0001), respectively) (construct validation). Overall, PS correlated highly with GEARS (ρ = 0.81, p < 0.0001) (concurrent validity). ICC was 0.77 (95 % CI 0.61-0.88) for resident evaluations. Structured learning can be implemented in an academic robotic program with high levels of trainee and evaluator participation, encouraging both quantitative and verbal feedback. A proficiency assessment tool developed for step-specific proficiency has construct and concurrent validity.

There is a lack of valid, reliable, and feasible instruments for measuring planar active cervical range of motion (aCROM) and associated 3D coupling motions in patients with neck pain. Smartphones have advanced sensors and appear to be suitable for these measurements. To estimate the concurrent validity and interrater reliability of a new iPhone application for assessing planar aCROM and associated 3D coupling motions in patients with neck pain, using an electromagnetic tracking device as a reference test. Cross-sectional study. Two samples of neck pain patients were recruited; 30 patients for the validity study and 26 patients for the reliability study. Validity was estimated using intraclass correlation coefficients (ICCs), and by calculating 95% limits of agreement (LoA). To estimate interrater reliability, ICCs were calculated. Cervical 3D coupling motions were analyzed by calculating the cross-correlation coefficients and ratio between the main motions and coupled motions for both instruments. ICCs for concurrent validity and interrater reliability ranged from 0.90 to 0.99. The width of the 95% LoA ranged from about 5° for right lateral bending to 11° for total rotation. No significant differences were found between both devices for associated coupling motion analysis. The iPhone application appears to be a useful discriminative tool for the measurement of planar aCROM and associated coupling motions in patients with neck pain. It fulfills the need for a valid, reliable, and feasible instrument in clinical practice and research. Therapists and researchers should consider measurement error when interpreting scores.

Rate of misdiagnosis of disorders of consciousness (DoC) can be reduced by employing validated clinical diagnostic tools, such as the Coma Recovery Scale-Revised (CRS-R). An Italian version of the CRS-R has been recently developed, but its applicability across different clinical settings, and its concurrent validity and diagnostic sensitivity have not been estimated yet. To perform a multicentre validation study of the Italian version of the Coma Recovery Scale-Revised (CRS-R). Analysis of inter-rater reliability, concurrent validity and diagnostic sensitivity of the scale. One Intensive Care Unit, 8 Post-acute rehabilitation centres and 2 Long-term facilities Twenty-seven professionals (physicians, N.=11; psychologists, N.=5; physiotherapists, N.=3; speech therapists, N.=6; nurses, N.=2) from 11 Italian Centres. CRS-R and Disability Rating Scale (DRS) applied to 122 patients with clinical diagnosis of Vegetative State (VS) or Minimally Conscious State (MCS). CRS-R has good-to-excellent inter-rater reliability for all subscales, particularly for the communication subscale. The Italian version of the CRS-R showed a high sensitivity and specificity in detecting MCS with reference to clinical consensus diagnosis. The CRS-R showed good concurrent validity with the Disability Rating Scale, which had very low specificity with reference to clinical consensus diagnosis. The Italian version of the CRS-R is a valid scale for use from the sub-acute to chronic stages of DoC. It can be administered reliably by all members of the rehabilitation team with different specialties, levels of experience and settings. The present study promote use of the Italian version of the CRS-R to improve diagnosis of DoC patients, and plan tailored rehabilitation treatment.

Background Although insulin therapy is well-accepted by symptomatic diabetic patients, it is still often delayed in less severe patients, in whom injectable insulin remains under-used. A better understanding of patients' perception of insulin would eventually help physicians to adopt the most appropriate dialogue when having to motivate patients to initiate or to intensify insulin injection. Methods The 'Studying the Hurdles of Insulin Prescription' (SHIP) questionnaire was developed based on a list of concepts derived from three diabetic patients' focus groups, and was included into two cross-sectional studies with similar design: SHIP Oral study and SHIP Premix study. Diabetic patients treated with oral hypoglycaemic agents (OHA; n = 1,494) and patients already treated with insulin (n = 1,150) completed the questionnaire at baseline, 6- and 12 months. Psychometric properties were assessed: 1) structure analysis by Principal Component Analysis (PCA) with Varimax rotation, 2) internal consistency reliability (Cronbach's alpha), and 3) concurrent validity (Spearman correlation coefficients with the Fear of Self-Injecting (FSI) score of the Diabetes Fear of Injecting and Self-testing Questionnaire. Reluctance/motivation towards insulin was assessed. Scores' ability to predict patients' insulin injection reluctance/motivation and initiation/intensification was evaluated with the Area Under the Receiver Operating Characteristic (ROC) Curve (AUC). Results PCA analysis confirmed the structure of the 14 items grouped into 3 dimensions: 'acceptance and motivation', 'fear and constraints', and 'restraints and barriers' towards insulin injection. Internal consistency reliability was excellent (Cronbach's alpha > 0.70); concurrent validity was good. The three scores were significantly predictive of patients' reluctance/motivation towards insulin injection initiation, as they were of patients' actual switch, except for the 'restraints and barriers' dimension. 'Acceptance and motivation' and 'fears and constraints' dimensions were also significantly predictive of patients' reluctance/motivation towards insulin intensification. By the end of the 12-month study, 179 of the initially OHA-treated patients had started insulin injections; 186 of the patients already treated with insulin had increased their injections. Conclusion The SHIP questionnaire provides reliable and valid assessment of diabetic patients' attitude towards insulin and injections. The predictive power of scores for patients' reluctance/motivation and actual treatment decisions demonstrates encouraging potential for further application in clinical practice. PMID:17727695

This study seeks to investigate the psychometric properties of the short version of the revised 'Experience of Close Relationships' questionnaire, comparing non-clinical and clinical samples. In total 702 subjects participated in this study, of whom 531 were non-clinical participants and 171 were psychiatric patients. They completed the short version of the revised 'Experience of Close Relationships' questionnaire (ECR-R-18), the Perceived Stress Scale-10(PSS-10), the Rosenberg Self-Esteem Scale (RSES) and the UCLA Loneliness scale. A retest of the ECR-R-18 was then performed at four-week intervals. Then, confirmatory factor analyses were performed to test the validity of the new scale. The ECR-R-18 showed a fair to good internal consistency (α 0.77 to 0.87) for both samples, and the test-retest reliability was found to be satisfactory (ICC = 0.75). The anxiety sub-scale demonstrated concurrent validity with PSS-10 and RSES, while the avoidance sub-scale showed concurrent validity with the UCLA Loneliness Scale. Confirmatory factor analysis using method factors yielded two factors with an acceptable model fit for both groups. An invariance test revealed that the ECR-R-18 when used on the clinical group differed from when used with the non-clinical group. The ECR-R-18 questionnaire revealed an overall better level of fit than the original 36 item questionnaire, indicating its suitability for use with a broader group of samples, including clinical samples. The reliability of the ECR-R- 18 might be increased if a modified scoring system is used and if our suggestions with regard to future studies are followed up.

An increasing need exists for suitable measures to evaluate treatment outcome in adolescents. YP-CORE is a pan-theoretical brief questionnaire developed for this purpose, but it lacks studies in different cultures or languages. To explore the acceptability, factor structure, reliability, validity, and sensitivity to change of the Finnish translation of YP-CORE. The study was conducted at the Department of Adolescent Psychiatry, Helsinki University Central Hospital. A Finnish translation was prepared by a team of professionals and adolescents. A clinical sample of 104 patients was asked to complete the form together with BDI-21 and BAI, and 92 of them filled the forms again after a 3-month treatment. Analysis included acceptability, confirmatory factor analysis, internal and test-re-test reliability, concurrent validity, influence of gender and age, and criteria for reliable change. YP-CORE was well accepted, and the rate of missing values was low. Internal consistency (α = 0.83-.92) and test-re-test reliability were good (r = 0.69), and the results of CFA supported a one-factor model. YP-CORE showed good concurrent validity against two widely used symptom-specific measures (r = 0.62-0.87). Gender had a moderately strong effect on the scores (d = 0.67), but the effect of age was not as evident. The measure was sensitive to change, showing a larger effect size (d = 0.55) than in the BDI-21 and BAI (d = 0.31-0.50). The results show that the translation of YP-CORE into Finnish has been successful, the YP-CORE has good psychometric properties, and the measure could be taken into wider use in clinical settings for outcome measurement in adolescents.
