    2012-01-01

    Lee Cronbach once expressed the view that all roads lead to construct validity. In looking to clarify the consensus definition of validity, and its place in assessment, Newton is also led to the troublesome idea of construct validity. To be sure, he addresses other validity issues, but in this commentary, I will restrict my attention to construct…

    The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…

  4. Switching off angiogenic signalling: creating channelled constructs for adequate oxygen delivery in tissue engineered constructs.

    Cheema, U; Alekseeva, T; Abou-Neel, E A; Brown, R A

    2010-10-06

    A major question in biomimetic tissue engineering is how much of the structure/function of native vasculature needs to be reproduced for effective tissue perfusion. O2 supplied to cells in 3D scaffolds in vitro is initially dependent upon diffusion through the scaffold and cell consumption. Low O2 (3%) enhances specific cell behaviours, but where O2 is critically low (pathological hypoxia) cell survival becomes compromised. We measured real-time O2 in 3D scaffolds and introduced micro-channelled architecture to controllably increase delivery of O2 to cells and switch off the hypoxic response. Simple static micro-channelling gives adequate perfusion and can be used to control cell generated hypoxia-induced signalling.

  5. Construct Validity: Advances in Theory and Methodology

    Strauss, Milton E.; Smith, Gregory T.

    2008-01-01

    Measures of psychological constructs are validated by testing whether they relate to measures of other constructs as specified by theory. Each test of relations between measures reflects on the validity of both the measures and the theory driving the test. Construct validation concerns the simultaneous process of measure and theory validation. In this chapter, we review the recent history of validation efforts in clinical psychological science that has led to this perspective, and we review five recent advances in validation theory and methodology of importance for clinical researchers. These are: the emergence of nonjustificationist philosophy of science; an increasing appreciation for theory and the need for informative tests of construct validity; valid construct representation in experimental psychopathology; the need to avoid representing multidimensional constructs with a single score; and the emergence of effective new statistical tools for the evaluation of convergent and discriminant validity.

  7. Drive: Theory and Construct Validation

    PubMed Central

    Petrides, K. V.

    2016-01-01

    This article explicates the theory of drive and describes the development and validation of two measures. A representative set of drive facets was derived from an extensive corpus of human attributes (Study 1). Operationalised using an International Personality Item Pool version (the Drive:IPIP), a three-factor model was extracted from the facets in two samples and confirmed on a third sample (Study 2). The multi-item IPIP measure showed congruence with a short form, based on single-item ratings of the facets, and both demonstrated cross-informant reliability. Evidence also supported the measures’ convergent, discriminant, concurrent, and incremental validity (Study 3). Based on very promising findings, the authors hope to initiate a stream of research in what is argued to be a rather neglected niche of individual differences and non-cognitive assessment.

    PubMed

    Denckla, Christy A; Bornstein, Robert F; Mancini, Anthony D; Bonanno, George A

    2015-06-01

    The Relationship Profile Test is a widely used measure of dependency, detachment, and healthy dependency that has been examined in both clinical and nonclinical settings, though researchers have yet to validate this measure among conjugally bereaved adults. The present study examines the construct validity of a three-facet model of dependency-detachment by comparing relationships among self-report, semistructured interview-rated, and knowledgeable informant-rated functioning among conjugally bereaved adults. Participants (N = 112) included bereaved adults (M = 51.1 years; SD = 9.7) who had experienced the loss of a spouse 1.5 to 3 years prior to taking part in this study. Findings indicate adequate psychometric properties and theoretically expected associations with various measures of wellness and health including satisfaction with life, coping flexibility, somatic complaints, and ego resiliency. Results draw attention to adaptive correlates of dependency, suggesting potentially beneficial mental health interventions.

  13. Beliefs about language development: construct validity evidence.

    PubMed

    Donahue, Mavis L; Fu, Qiong; Smith, Everett V

    2012-01-01

    Understanding language development is incomplete without recognizing children's sociocultural environments, including adult beliefs about language development. Yet there is a need for data supporting valid inferences to assess these beliefs. The current study investigated the psychometric properties of data from a survey (MODeL) designed to explore beliefs in the popular culture, and their alignment with more formal theories. Support for the content, substantive, structural, generalizability, and external aspects of construct validity of the data were investigated. Subscales representing Behaviorist, Cognitive, Nativist, and Sociolinguistic models were identified as dimensions of beliefs. More than half of the items showed a high degree of consensus, suggesting culturally-transmitted beliefs. Behaviorist ideas were most popular. Bilingualism and ethnicity were related to Cognitive and Sociolinguistic beliefs. Identifying these beliefs may clarify the nature of child-directed speech, and enable the design of language intervention programs that are congruent with family and cultural expectations.

  14. Construct Validation of the Physics Metacognition Inventory

    NASA Astrophysics Data System (ADS)

    Taasoobshirazi, Gita; Farley, John

    2013-02-01

    The 24-item Physics Metacognition Inventory was developed to measure physics students' metacognition for problem solving. Items were classified into eight subcomponents subsumed under two broader components: knowledge of cognition and regulation of cognition. The students' scores on the inventory were found to be reliable and related to students' physics motivation and physics grade. An exploratory factor analysis provided evidence of construct validity, revealing six components of students' metacognition when solving physics problems including: knowledge of cognition, planning, monitoring, evaluation, debugging, and information management. Although women and men differed on the components, they had equivalent overall metacognition for problem solving. The implications of these findings for future research are discussed.

  16. Assessing the construct validity of aberrant salience.

    PubMed

    Schmidt, Kristin; Roiser, Jonathan P

    2009-01-01

    We sought to validate the psychometric properties of a recently developed paradigm that aims to measure salience attribution processes proposed to contribute to positive psychotic symptoms, the Salience Attribution Test (SAT). The "aberrant salience" measure from the SAT showed good face validity in previous results, with elevated scores both in high-schizotypy individuals, and in patients with schizophrenia suffering from delusions. Exploring the construct validity of salience attribution variables derived from the SAT is important, since other factors, including latent inhibition/learned irrelevance (LIrr), attention, probabilistic reward learning, sensitivity to probability, general cognitive ability and working memory could influence these measures. Fifty healthy participants completed schizotypy scales, the SAT, a LIrr task, and a number of other cognitive tasks tapping into potentially confounding processes. Behavioural measures of interest from each task were entered into a principal components analysis, which yielded a five-factor structure accounting for approximately 75% of the variance in behaviour. Implicit aberrant salience was found to load onto its own factor, which was associated with elevated "Introvertive Anhedonia" schizotypy, replicating our previous finding. LIrr loaded onto a separate factor, which also included implicit adaptive salience, but was not associated with schizotypy. Explicit adaptive and aberrant salience, along with a measure of probabilistic learning, loaded onto a further factor, though this also did not correlate with schizotypy. These results suggest that the measures of LIrr and implicit adaptive salience might be based on similar underlying processes, which are dissociable both from implicit aberrant salience and explicit measures of salience.

  6. The Religious Support Scale: construction, validation, and cross-validation.

    PubMed

    Fiala, William E; Bjorck, Jeffrey P; Gorsuch, Richard

    2002-12-01

    Cutrona and Russell's social support model was used to develop a religious support measure (C. E. Cutrona & D. W. Russell, 1987), including 3 distinct but related subscales respectively measuring support from God, the congregation, and church leadership. Factor analyses with the main sample's data (249 Protestants) and cross-validation (93 additional Protestants) supported the scales' reliability and validity. All 3 types of religious support were related to lower depression and greater life satisfaction. Moreover, several relationships between the 3 subscales and psychological functioning variables remained significant after controlling for variance because of church attendance and social support. Results suggest that religious attendance does not automatically imply religious support, and that religious support can provide unique resources for religious persons, above and beyond those furnished by social support. Findings are discussed regarding relevance to community psychology.

  7. Construction and factorial validation of a short form of the Self-Compassion Scale.

    PubMed

    Raes, Filip; Pommier, Elizabeth; Neff, Kristin D; Van Gucht, Dinska

    2011-01-01

    The objective of the present study was to construct and validate a short-form version of the Self-Compassion Scale (SCS). Two Dutch samples were used to construct and cross-validate the factorial structure of a 12-item Self-Compassion Scale-Short Form (SCS-SF). The SCS-SF was then validated in a third, English sample. The SCS-SF demonstrated adequate internal consistency (Cronbach's alpha ≥ 0.86 in all samples) and a near-perfect correlation with the long form SCS (r ≥ 0.97 all samples). Confirmatory factor analysis on the SCS-SF supported the same six-factor structure as found in the long form, as well as a single higher-order factor of self-compassion. The SCS-SF thus represents a reliable and valid alternative to the long-form SCS, especially when looking at overall self-compassion scores.

    2006-01-01

    Hospitals continuously look for ways to improve patient care and retain high-quality physicians. Previous research indicates that physicians' satisfaction with where they practice is a crucial part of addressing these issues. A reliable and valid method to assess physician satisfaction is needed in order to identify potential areas of discontent. The purpose of the present study was to develop and validate a self-administered medical staff satisfaction survey. The survey contains 13 Likert-type items divided into three reliable subscales: Quality of Patient Care (alpha = .84), Ease of Practice (alpha = .76), and Relationship with Leadership (alpha = .92). Results from both exploratory and confirmatory factor analyses supported the survey's structure and robustness across three independent samples.

    PubMed

    Binks-Cantrell, Emily; Joshi, R Malatesha; Washburn, Erin K

    2012-10-01

    Recent national reports have stressed the importance of teacher knowledge in teaching reading. However, in the past, teachers' knowledge of language and literacy constructs has typically been assessed with instruments that are not fully tested for validity. In the present study, an instrument was developed; and its reliability, item difficulty, and item discrimination were computed and examined to identify model fit by applying exploratory factor analysis. Such analyses showed that the instrument demonstrated adequate estimates of reliability in assessing teachers' knowledge of language constructs. The implications for professional development of in-service teachers as well as preservice teacher education are also discussed.

    Foss, I.; Woolf, D. K.; Gagnon, A. S.; Merchant, C. J.

    2010-05-01

    For the purpose of identifying potential sources of predictability of Scottish mean air temperature (SMAT), a redundancy analysis (RA) was accomplished to quantitatively assess the predictability of SMAT from North Atlantic SSTs as well as the temporal consistency of this predictability. The RA was performed between the main principal components of North Atlantic SST anomalies and SMAT anomalies for two time periods: 1890-1960 and 1960-2006. The RA models developed using data from the 1890-1960 period were validated using the 1960-2006 period; in a similar way the model developed based on the 1960-2006 period was validated using data from the 1890-1960 period. The results indicate the potential to forecast decadal trends in SMAT for all seasons in 1960-2006 time period and all seasons with the exception of winter for the period 1890-1960 with the best predictability achieved in summer. The statistical models show the best performance when SST anomalies in the European shelf seas (45°N-65°N, 20W-20E) rather than those for the SSTs over the entire North Atlantic (30°N-75°N, 80°W-30°E) were used as a predictor. The results of the RA demonstrated that similar SSTs modes were responsible for predictions in the first and second half of the 20th century, establishing temporal consistency, though with stronger influence in the more recent half. The SST pattern responsible for explaining the largest amount of variance in SMAT was stronger in the second half of the 20th century and showed increasing influence from the area of the North Sea, possibly due to faster sea-surface warming in that region in comparison with the open North Atlantic. The Wavelet Transform (WT), Cross Wavelet Transform (XWT) and Wavelet Coherence (WTC) techniques were used to analyse RA-model-based forecasts of SMAT in the time-frequency domain. Wavelet-based techniques applied to the predicted and observed time series revealed a good performance of RA models to predict the frequency variability

  20. Utility of pedometers for assessing physical activity: construct validity.

    PubMed

    Tudor-Locke, Catrine; Williams, Joel E; Reis, Jared P; Pluto, Delores

    2004-01-01

    Valid assessment of physical activity is necessary to fully understand this important health-related behaviour for research, surveillance, intervention and evaluation purposes. This article is the second in a companion set exploring the validity of pedometer-assessed physical activity. The previous article published in Sports Medicine dealt with convergent validity (i.e. the extent to which an instrument's output is associated with that of other instruments intended to measure the same exposure of interest). The present focus is on construct validity. Construct validity is the extent to which the measurement corresponds with other measures of theoretically-related parameters. Construct validity is typically evaluated by correlational analysis, that is, the magnitude of concordance between two measures (e.g. pedometer-determined steps/day and a theoretically-related parameter such as age, anthropometric measures and fitness). A systematic literature review produced 29 articles published since > or =1980 directly relevant to construct validity of pedometers in relation to age, anthropometric measures and fitness. Reported correlations were combined and a median r-value was computed. Overall, there was a weak inverse relationship (median r = -0.21) between age and pedometer-determined physical activity. A weak inverse relationship was also apparent with both body mass index and percentage overweight (median r = -0.27 and r = -0.22, respectively). Positive relationships regarding indicators of fitness ranged from weak to moderate depending on the fitness measure utilised: 6-minute walk test (median r = 0.69), timed treadmill test (median r = 0.41) and estimated maximum oxygen uptake (median r = 0.22). Studies are warranted to assess the relationship of pedometer-determined physical activity with other important health-related outcomes including blood pressure and physiological parameters such as blood glucose and lipid profiles. The aggregated evidence of convergent

  1. Toys and gadgets: construct validity of apathy in Parkinson's disease.

    PubMed

    2012-01-01

    Apathy is one of the primary neuropsychiatric signatures in Parkinson's disease, yet little research has addressed the construct validity of two commonly used apathy measures, the Apathy Scale and the Lille Apathy Rating Scale. The authors tested the hypothesis that apathy is associated with reduced initiative/engaged behaviors on a laboratory-based measure of apathy. Support was found for the hypothesis that apathy, as indexed by the Apathy Scale and the Lille Apathy Rating Scale, is associated with reduced initiative/engagement on an experimental measure of apathy in Parkinson's disease patients. These findings provide independent evidence for the construct validity of self-report apathy scales, beyond clinician judgment.

    Given the influence of social conformity and prejudice, defendants pleading not guilty by reason of insanity face the significant challenges of securing fair and impartial juries. Attitudes and knowledge of the insanity defense are factors that may influence levels of impartiality. In the light of this, we set out to develop a scale to examine knowledge levels of the insanity defense and their influence on decision-making. Two studies were conducted to construct a scale designed to assess laypersons' knowledge of the insanity defense. Items measuring knowledge of the insanity defense were based on Perlin's (1995) insanity defense myths. The first study identified particular items in need of revision and subscales that required the development of additional items in order to improve reliability and construct validity in the second study. The second study used the revised scale, demonstrating improved validity and reliability. The scale also had acceptable predictive validity with reference to insanity defense verdicts.

    Construct and concurrent validity of the Korean Career Indecision Inventory were examined. Data were collected from 238 South Korean college students. A confirmatory factor analysis supported the original five-factor model. As hypothesized, scores were significantly correlated with various variables such as scores on the Korean versions of the Career Decision Scale (r =.49), the Vocational Identity Scale in My Vocational Situation (r=-.63), the Career Decision-making Self-efficacy Scale (r=-.47), and Negative Affectivity (r=.37). These results support construct validity inventory. Students who indicated they were undecided about their careers had significantly higher scores than those who indicated they had decided on a career, supporting concurrent validity. Implications and limitations are discussed.

    OBJECTIVE: The current study aimed to validate the construct and reliability of an emotional intelligence scale. METHOD: The Trait Meta-Mood Scale-24 was applied to 349 nursing students. The process included content validation, which involved expert reviews, pilot testing, measurements of reliability using Cronbach's alpha, and factor analysis to corroborate the validity of the theoretical model's construct. RESULTS: Adequate Cronbach coefficients were obtained for all three dimensions, and factor analysis confirmed the scale's dimensions (perception, comprehension, and regulation). CONCLUSION: The Trait Meta-Mood Scale is a reliable and valid tool to measure the emotional intelligence of nursing students. Its use allows for accurate determinations of individuals' abilities to interpret and manage emotions. At the same time, this new construct is of potential importance for measurements in nursing leadership; educational, organizational, and personal improvements; and the establishment of effective relationships with patients.

    Training students to perform emergency procedures is a critical but challenging component of veterinary education. Thoracocentesis is traditionally taught in the classroom, with students progressing to "see one, do one, teach one" during the clinical phase of their education. This method of teaching does not permit students to gain proficiency before performing thoracocentesis on a live animal in a high-stakes, high-stress environment and is dependent on the availability of animals requiring the procedure. A veterinary thoracocentesis simulator has been created to allow students an opportunity for repetitive practice in a low-stakes environment. This study evaluated the face, content, and construct validity of the thoracocentesis simulator. Face and content validation were confirmed by survey results, and construct validity was assessed through comparison of student and veterinarian performance on the simulator. Students' median checklist and global rating scores were significantly lower than those of the veterinarians, and students took significantly longer to perform the procedure, indicating that the simulator was able to differentiate the relative expertise of the user and establishing construct validity. This study supported the use of the thoracocentesis simulator for educators to demonstrate proper technique, for students to practice the steps needed to perform the procedure and experience an approximation of the tactile aspects of the task, and for formative assessment before performing the procedure on client-owned animals.

    The Emotional Appetite Questionnaire (EMAQ) comprises ratings of tendency to eat in response to both positive and negative, emotions and situations. To assess construct validity, the responses of 232 male and female participants to the EMAQ subscales were correlated with the subscales of the Dutch Eating Behavior Questionnaire (DEBQ), which has been extensively validated. In addition, the EMAQ scores were correlated with BMI. Convergent validity was demonstrated by a significant positive correlation between the negative emotions and situations scores of the EMAQ and the emotional eating subscale score of the DEBQ (DEBQ-E). Moreover, discriminant validity was demonstrated by low correlations of EMAQ positive emotions and situations scores with the DEBQ-E score. For the study sample, the EMAQ negative scores were significantly positively correlated with BMI, and the EMAQ positive scores were significantly inversely correlated with BMI. As BMI increased so did reported negative emotional and situational eating whereas as BMI decreased, reported positive emotional and situational eating increased. Although causality cannot be inferred from correlations, eating more under negative emotions may contribute to being overweight whereas eating less may contribute to being underweight. The EMAQ was shown to have construct validity, and emotional eating was significantly correlated with BMI.

    Affect integration, or the capacity to utilize the motivational and signal properties of affect for personal adjustment, is assumed to be an important aspect of psychological health and functioning. Affect integration has been operationalized through the affect consciousness (AC) construct as degrees of awareness, tolerance, nonverbal expression, and conceptual expression of nine discrete affects. A semistructured Affect Consciousness Interview (ACI) and separate Affect Consciousness Scales (ACSs) have been developed to specifically assess these aspects of affect integration. This study explored the construct validity of AC in a Norwegian clinical sample including estimates of reliability and assessment of structure by factor analyses. External validity issues were addressed by examining the relationships between scores on the ACSs and self-rated symptom- and interpersonal problem measures as well as independent, observer-based ratings of personality disorder criteria and the Global Assessment of Functioning (GAF) scale from the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994).

    The Cerebral Palsy Quality of Life for Children (CP QOL-Child) is the first health condition-specific questionnaire designed for measuring QOL in children with cerebral palsy (CP). However, its construct validity has not yet been confirmed by confirmatory factor analysis (CFA). Hence, this study assessed the construct validity of the caregiver proxy-report version of the Chinese version of the CP QOL-Child in children with CP using CFA. A total of 312 children with CP (mean age: 8.59 years, SD: 2.52 years) and their caregivers participated in this study. The Chinese version of the CP QOL-Child was completed by the caregivers of children with CP. Then, CFA was applied to evaluate the seven-factor measurement structure of the CP QOL-Child. The seven-factor CFA model had an adequate fit to our data as judged by χ(2) statistic and various goodness-of-fit (GOF) indices, including the root mean square error of approximation (RMSEA). This study provided empirical evidence of the construct validity of the CP QOL-Child to support its use with children with CP in the Chinese speaking society.

    Some studies have concluded there is a relationship between perceived self-efficacy and behaviors that prevent HIV transmission. This paper presents the construction and validation of the latex barrier use self-efficacy scale (LBSS), which 480 participants filled out. Exploratory factor analysis yielded two components: positive expectations of self-efficacy (ES-POS) and negative expectations of self-efficacy (ES-NEG), which together accounted for 65.59% of total variance. That structure was later verified through confirmatory factor analysis. Internal consistency was .80 for the total scale, and .78 for each of the two factors. Moreover, the instrument had adequate convergent validity and was positively related with condom use self-efficacy, attitudes toward condom and latex barrier use, and ability to refuse sex if the partner refuses to use preventive methods. In conclusion, this instrument is a useful measure of self-efficacy in latex barrier use.

    We examined the construct validity of the Rotter Incomplete Sentence Blank (RISB; Rotter, Lah, & Rafferty, 1992) as a measure of psychological maladjustment in adolescents. In Study 1, we investigated the reliability and convergent and discriminant validity of the RISB with adolescents referred to treatment. In Studies 2 and 3, we examined the RISB's ability to differentiate referred and nonreferred adolescents. The RISB showed adequate interrater reliability and converged with self-reported, parent-reported, and teacher-reported social-emotional and behavioral problems. Criterion-related evidence suggests that the RISB may be useful as a screening measure for adolescents using a 135 or 140 cut score. We provide normative data to facilitate the test's use with adolescents in clinical and research settings.

  1. Overactivity in chronic pain: is it a valid construct?

    PubMed

    Andrews, Nicole Emma; Strong, Jenny; Meredith, Pamela Joy

    2015-10-01

    Overactivity is a frequently used term in chronic pain literature. It refers to the phenomenon whereby individuals engage in activity in a way that significantly exacerbates pain, resulting in periods of incapacity. Overactivity, as a construct, has been derived solely from patients' self-reports, raising concerns about the legitimacy of the construct. Self-reported overactivity reflects an individual's "belief," collected retrospectively, that their earlier activity levels have resulted in increased levels of pain. This may be different to an individual actually engaging in activity in a way that significantly exacerbates pain. In this study, a 5-day observational study design was used to investigate the validity of overactivity as a construct by examining the relationship between a self-report measure of overactivity, patterns of pain, and objectively measured physical activity over time. A sample of 68 adults with chronic pain completed a questionnaire investigating self-reported habitual engagement in overactivity and activity avoidance behaviour, before commencing 5 days of data collection. Over the 5-day period, participants wore an activity monitor and recorded their pain intensity 6 times a day using a handheld computer. Associations were found between (1) high levels of pain and both high overactivity and high avoidance, (2) high levels of overactivity and more variation in pain and objective activity across days, and (3) high levels of overactivity and the reoccurrence of prolonged activity engagement followed by significant pain increases observed in data sets. These results offer some preliminary support for the validity of overactivity as a legitimate construct in chronic pain.

    Person-environment fit (P-E fit) was initially espoused as an important construct in the field of community psychology; however, most of the theoretical and empirical development of the construct has been conducted by industrial/organizational (I/O) psychologists. In the current study, the GEFS—a P-E fit measure was developed from I/O and business management perspectives on fit—was administered to 246 attendees of an annual convention for residents and alumni of Oxford House (OH), a network of over 1400 mutual-help recovery homes. The authors conducted confirmatory factor and convergent construct validity analyses on the GEFS. The results suggested that the theoretical factor structure of the measure adequately fit the data, suggesting that the GEFS is a valid measure of P-E fit. OH resident fit with their recovery home was related to satisfaction, but not expected tenure. Exploratory analyses revealed that the sufficient supply of resident needs by the recovery home and similarity between residents and their housemates predicted satisfaction with the recovery home, but only similarity with housemates predicted how long residents intended to stay in the OHs.

    A strategy has been developed for the construction of a validated, comprehensive composite protein sequence database. Entries are amalgamated from primary source data bases by a largely automated set of processes in which redundant and trivially different entries are eliminated. A modular approach has been adopted to allow scientific judgement to be used at each stage of database processing and amalgamation. Source databases are assigned a priority depending on the quality of sequence validation and commenting. Rejection of entries from the lower priority database, in each pairwise comparison of databases, is carried out according to optionally defined redundancy criteria based on sequence segment mismatches. Efficient algorithms for this methodology are embodied in the COMPO software system. COMPO has been applied for over 2 years in construction and regular updating of the OWL composite protein sequence database from the source databases NBRF-PIR, SWISS-PROT, a GenBank translation retrieved from the feature tables, NBRF-NEW, NEWAT86, PSD-KYOTO and the sequences contained in the Brookhaven protein structure databank. OWL is part of the ISIS integrated data resource of protein sequence and structure [Akrigg et al. (1988) Nature, 335, 745-746]. The modular nature of the integration process greatly facilitates the frequent updating of OWL following releases of the source databases. The extent of redundancy in these sources is revealed by the comparison process. The advantages of a robust composite database for sequence similarity searching and information retrieval are discussed.

    Background and Objective: The use of training models in laparoscopic surgery allows the surgical team to practice procedures in a safe environment. The aim of this study was to determine the capability of an inanimate laparoscopic appendectomy model to discriminate between different levels of surgical experience (construct validity). Methods: The performance of 3 groups with different levels of expertise in laparoscopic surgery—experts (Group A), intermediates (Group B), and novices (Group C)—was evaluated. The groups were instructed of the task to perform in the model using a video tutorial. Procedures were recorded in a digital format for later analysis using the Global Operative Assessment of Laparoscopic Skills (GOALS) score; procedure time was registered. The data were analyzed using the analysis of variance test. Results: Twelve subjects were evaluated, 4 in each group, using the GOALS score and time required to finish the task. Higher scores were observed in the expert group, followed by the intermediate and novice groups, with statistically significant difference. Regarding procedure time, a significant difference was also found between the groups, with the experts having the shorter time. The proposed model is able to discriminate among individuals with different levels of expertise, indicating that the abilities that the model evaluates are relevant in the surgeon's performance. Conclusions: Construct validity for the inanimate full-task laparoscopic appendectomy training model was demonstrated. Therefore, it is a useful tool in the development and evaluation of the resident in training. PMID:24018084

    The objective was to construct and validate a Chinese-language Meaning in Life Scale (MiLS) and to assess its psychometric properties. The three most popular scales have some weaknesses and are grounded in a Western cultural context. Consequently, a comprehensive and psychometrically adequate meaning in life scale is needed for use in Asian samples. 500 randomly selected participants from the Taiwanese public provided 476 valid responses to a written questionnaire. The participants' ages ranged from 18 to 63 years (M age = 42.3 yr.; 181 men, 295 women). Exploratory factor analysis reduced the initial 41 items to 33 items, based on a 5-point rating scale. Five factors were extracted: Contented with life (10 items; 33.20% of total variance), Goals in life (5 items; 6.95%), Enthusiasm and commitment (7 items; 6.28%), Understanding (6 items; 5.41%), and Sense or meaning to human existence (5 items; 4.57%). The MiLS showed satisfactory internal consistency and test-retest reliability, and concurrent validity. Therefore, the MiLS was found to be a valid and reliable instrument to measure the subjective sense of a meaning in life in the Taiwanese cultural context.

    Background: Healthy lifestyle is a significant factor in cancer etiologic and prevention of cancer. There are instruments to measure a healthy life style, but the lifestyle questionnaires only examine one or a few more aspects of lifestyle. Objectives: The purpose of this study was to construct a comprehensive instrument to examine all aspects of lifestyle related to cancer. Materials and Methods: This study was a cross-sectional study that was conducted in Yazd city in Iran. A questionnaire was designed to assess and measure various aspects of lifestyle related to cancer using similar studies. Researchers used the Cronbach’s alpha and test-retest method to determine the reliability. Also, construct validity was determined using the factor analysis method in SPSS 16 software. Results: Face validity was examined using a panel of experts. Cronbach’s alpha for the whole scale was appropriate (α = 0.87). Also, Cronbach’s alpha for all dimensions of questionnaire was acceptable (perfect score). Test-retest method was used to determine the reliability. The results indicated that ICC was in the range of 0.84 to 0.94. Based on the obtained results of factor analysis method, 8 dimensions of the questionnaire were extracted (physical health, physical activity and exercise, mental health, drug and alcohol avoidance, balanced consumption of food, environmental pollutants and harmful substances, weight control and nutrition, and reproductive health). Conclusions: This study showed that the present questionnaire can be used as a valid and reliable tool for collecting data about the lifestyle of people related to cancer. PMID:26634112

    The Dyadic Coping Inventory (DCI, Bodenmann, 2008) assesses how couples support each other when facing individual (e.g., workload) and common (e.g., parenting) stressors. Specifically, the DCI measures partners' perceptions of their own (Self) and their partners' behaviors (Partner) when facing individual stressors, and partners' common coping behaviors when facing common stressors (Common). To date, the DCI has been validated in 6 different languages from individualistic Western cultures; however, because culture can affect interpersonal interactions, it is unknown whether the DCI is a reliable measure of coping behaviors for couples living in collectivistic Eastern cultures. Based on data from 474 Chinese couples (N = 948 individuals), the current study examined the Chinese version of the DCI's factorial structure, measurement invariance (MI), and construct validity of test scores. Using 3 cultural groups (China, Switzerland, and the United States [U.S.]), confirmatory factor analysis revealed a 5-factor structure regarding Self and Partner and a 2-factor structure regarding Common dyadic coping (DC). Results from analyses of MI indicated that the DCI subscales met the criteria for configural, metric, and full/partial scalar invariance across cultures (Chinese-Swiss and Chinese-U.S.) and genders (Chinese men and women). Results further revealed good construct validity of the DCI test scores. In all, the Chinese version of the DCI can be used for measuring Chinese couples' coping behaviors, and is available for cross-cultural studies examining DC behaviors between Western and Eastern cultures.

    Despite the application of Self-Efficacy Theory (Bandura, 1977, 2000) to many areas of psychology, there is a lack of research on self-efficacy in the ability to testify in court. The present study fills this gap by incrementally developing the construct of Witness Self-Efficacy and establishing its psychometric properties. Study I features exploratory and confirmatory factor analyses yielding a two-factor Witness Self-Efficacy Scale (WSES). The two components are Poise and Communication Style. Study II uses a second data collection to show that both WSES domains possess convergent, divergent, and predictive validity relations consistent with those expected using an SET framework. Notably, WSES components predicted perceptions of witness credibility and sentencing outcomes above and beyond witness extraversion, general self-efficacy, and general self-confidence. Implications for SET and witness preparation training are discussed. Copyright © 2010 John Wiley & Sons, Ltd.

    Purpose Many dietary factors have either pro- or anti-inflammatory properties. We previously developed a dietary inflammatory index (DII) to assess the inflammatory potential of diet. In this study we conducted a construct validation of the DII based on data from a food frequency questionnaire and three inflammatory biomarkers in a subsample of 2,567 postmenopausal women in the Women’s Health Initiative Observational Study. Methods We used multiple linear and logistic regression models, controlling for potential confounders, to test whether baseline DII predicted concentrations of interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor alpha receptor 2 (TNFα-R2), or an overall biomarker score combining all three inflammatory biomarkers. Results The DII was associated with the four biomarkers with beta estimates (95%CI) comparing the highest with lowest DII quintiles as follows: IL-6: 1.26 (1.15, 1.38), Ptrend<0.0001; TNFα-R2: 81.43 (19.15, 143.71), Ptrend=0.004; dichotomized hs-CRP (odds ratio for higher versus lower hs-CRP): 1.30 (0.97, 1.67), Ptrend=0.34); and the combined inflammatory biomarker score: 0.26 (0.12, 0.40), Ptrend=0.0001. Conclusion The DII was significantly associated with inflammatory biomarkers. Construct validity of the DII indicates its utility for assessing the inflammatory potential of diet and for expanding its use to include associations with common chronic diseases in future studies.

    2009-09-01

    The construct of narcissism is inconsistently defined across clinical theory, social-personality psychology, and psychiatric diagnosis. Two problems were identified that impede integration of research and clinical findings regarding narcissistic personality pathology: (a) ambiguity regarding the assessment of pathological narcissism vs. normal narcissism and (b) insufficient scope of existing narcissism measures. Four studies are presented documenting the initial derivation and validation of the Pathological Narcissism Inventory (PNI). The PNI is a 52-item self-report measure assessing 7 dimensions of pathological narcissism spanning problems with narcissistic grandiosity (Entitlement Rage, Exploitativeness, Grandiose Fantasy, Self-sacrificing Self-enhancement) and narcissistic vulnerability (Contingent Self-esteem, Hiding the Self, Devaluing). The PNI structure was validated via confirmatory factor analysis. The PNI correlated negatively with self-esteem and empathy, and positively with shame, interpersonal distress, aggression, and borderline personality organization. Grandiose PNI scales were associated with vindictive, domineering, intrusive, and overly-nurturant interpersonal problems, and vulnerable PNI scales were associated with cold, socially avoidant, and exploitable interpersonal problems. In a small clinical sample, PNI scales exhibited significant associations with parasuicidal behavior, suicide attempts, homicidal ideation, and several aspects of psychotherapy utilization.

    Hebephilia refers to a persistent intense sexual interest in pubescent children. Although not as widely studied as pedophilia, studies of hebephilia have indicated convergence in self-report and sexual arousal. The present study expanded on previous work by examining convergent and divergent validity across indicators of hebephilia that included self-report, sexual behavior, and sexual arousal in a sample of 2238 men who had sexually offended. We included men who denied such interest and specifically examined the overlap between hebephilia and pedophilia and examined pedohebephilia (i.e., sexual interests in both prepubescent and pubescent children). Results indicated that there was considerable convergence across indicators of hebephilia. The results suggested poor divergent validity between hebephilia and pedophilia, as there was substantial overlap between the two constructs across analyses. Finally, a distinct pattern of sexual arousal was found in offenders with pedohebephilia. The results of the present study were discussed with a focus on implications for the assessment of sexual interest in children and the conceptualization of pedohebephilia.

    2016-02-01

    In this rejoinder, we comment on Wright's response to our reanalysis and reinterpretation of the data presented by Wright and colleagues. Two primary differences characterize these perspectives. First, the conceptualization of grandiose narcissism differs such that emotional and ego vulnerability, dysregulation, and pervasive impairments are more characteristic of Wright's conception, likely due to the degree to which it is tied to clinical observations. Our conceptualization is closer to psychopathy and describes an extraverted, dominant, and antagonistic individual who is relatively less likely to be found in clinical settings. Second, our approach to construct validation differs in that we take an empirical perspective that focuses on the degree to which inventories yield scores consistent with a priori predictions. The grandiose dimension of the Pathological Narcissism Inventory (PNI-G) yields data that fail to align with expert ratings of narcissistic personality disorder and grandiose narcissism. We suggest that caution should be taken in treating the PNI-G as a gold standard measure of pathological narcissism, that revision of the PNI-G is required before it can serve as a stand-alone measure of grandiose narcissism, and that the PNI-G should be buttressed by other scales when being used as a measure of grandiose narcissism.

    Purpose To validate three early ejaculation diagnostic tools, and propose a new tool for diagnosis in line with proposed changes to diagnostic criteria. Significant changes to diagnostic criteria are expected in the near future. Available screening tools do not necessarily reflect proposed changes. Materials and Methods Data from 148 diagnosed early ejaculation patients (Mage = 42.8) and 892 controls (Mage = 33.1 years) from a population-based sample were used. Participants responded to three different questionnaires (Premature Ejaculation Profile; Premature Ejaculation Diagnostic Tool; Multiple Indicators of Premature Ejaculation). Stopwatch measured ejaculation latency times were collected from a subsample of early ejaculation patients. We used two types of responses to the questionnaires depending on the treatment status of the patients 1) responses regarding the situation before starting pharmacological treatment and 2) responses regarding current situation. Logistic regressions and Receiver Operating Characteristics were used to assess ability of both the instruments and individual items to differentiate between patients and controls. Results All instruments had very good precision (Areas under the Curve ranging from .93-.98). A new five-item instrument (named CHecklist for Early Ejaculation Symptoms – CHEES) consisting of high-performance variables selected from the three instruments had validity (Nagelkerke R2 range .51-.79 for backwards/forwards logistic regression) equal to or slightly better than any individual instrument (i.e., had slightly higher validity statistics, but these differences did not achieve statistical significance). Importantly, however, this instrument was more in line with proposed changes to diagnostic criteria. Conclusions All three screening tools had good validity. A new 5-item diagnostic tool (CHEES) based on the three instruments had equal or somewhat more favorable validity statistics compared to the other three tools, but is

    Limited data exist on the validity of the Late-Life Function and Disability (LLFD) instrument in cancer survivors. We examined the construct validity of the abbreviated LLFD instrument in a sample of African-American breast cancer survivors. African American breast cancer survivors (n = 181) aged 50 years and older completed the abbreviated LLFD instrument and questions about sociodemographic and lifestyle characteristics. Confirmatory factor analysis (CFA), Cronbach alphas, and structural models were used to evaluate the construct validity of these measures. Minor modifications were made to the three-factor functional component portion of the inventory to improve model fit. Cronbach alpha’s (range 0.85–0.92) and inter-factor correlations (r = 0.3–0.5, all p < 0.05) were appropriate. The two-factor disability component fit the data and Cronbach alpha’s (0.91 and 0.98) were appropriate with a high inter-factor correlation (r = 0.95, p < 0.01). The average variance extracted (range = 0.55–0.93) and composite reliabilities (range = 0.86–0.98) were in acceptable ranges. Floor effects ranged from 7% for advanced lower function to 74% for personal role disability. Education and number of comorbidities were correlated significantly with functional outcomes. The abbreviated LLFD instrument had adequate construct validity in this sample of African American breast cancer survivors. Further studies are needed that examine the stability of the instrument over time. PMID:27854321

    2011-01-01

    Background: Colleges and universities are becoming increasingly accountable for teaching outcomes in order to meet rigorous accreditation standards. Job satisfaction (JS) seems more difficult to measure in the academic field in view of the complexity of roles, duties and responsibilities. Objectives: To compile and determine the psychometric properties of a proposed Academic Job Satisfaction Questionnaire (AJSQ) suitable for university faculty, and amenable to future upgrading. Materials and Methods: A 46-item five-option Likert-type draft questionnaire on JS was distributed for anonymous self-reporting by all the academic staff of five colleges in University of Dammam (n=340). The outcome measures were (1) factor analysis of the questionnaire items, (2) intra-factor α-Coefficient of Internal Consistency Reliability, (3) inter-factor correlations, (4) comparison of psychometric properties in separately analyzed main faculty subgroups. Results: The response rate was 72.9 percent. Factor analysis extracted eight factors which conjointly explained 60.3 percent of the variance in JS. These factors, in descending order of eigenvalue, were labeled “Authority”, “Supervision”, “Policies and Facilities”, “My Work Itself”, “Interpersonal Relationships”, “Commitment”, “Salary” and “Workload”. Cronbach's-α ranged from 0.90 in Supervision to 0.63 in Salary and Workload. All inter-factor correlations were positive and significant, ranging from 0.65 to 0.23. The psychometric properties of the instrument in separately analyzed subgroups divided by sex, nationality, college and clinical duties produced fairly comparable findings. Conclusion: The AJSQ demonstrated good overall psychometric properties in terms of construct validity and internal consistency reliability in both the overall sample and its separately analyzed subgroups. Recommendation: To replicate these findings in larger multicenter samples of academic staff. PMID:21694952

    Development of diagnostic instruments directed toward neuropsychological assessment of preschoolers lags significantly behind those available for school-age children (DeWolfe, Byrne, & Bawden, 2000). This is particularly true for measures of executive function (EF). The Auditory Continuous Performance Test for Preschoolers (ACPT-P; Mahone, Pillion, & Hiemenz, 2001) is a computerized, Go-No-go test developed to measure selected EF skills in preschoolers. First, to determine whether performance on the ACPT-P is associated with hearing impairment, we compared performance of children with mild hearing loss (MHL) to controls on the ACPT-P, and measures of spatial working memory (SWM) and motor persistence (MP). There were no differences between performance of the MHL group and controls on any of these measures. Second, to examine the construct validity of the ACPT-P, we compared performance of 40 preschoolers with ADHD to 40 age- and sex-matched controls, using the ACPT-P to measure response preparation, sustained attention, and inhibitory control. We also compared these groups on measures of SWM and MP. The group with attention deficit hyperactivity disorder (ADHD) performed significantly worse than controls on the ACPT-P (omissions, mean response time, variability) and MP. The ACPT-P was correlated with the MP, but not with the SWM measure. Both the ACPT-P and the MP measures showed low to moderate correlations with parent ratings of behavior associated with ADHD. These findings support the use of performance-based assessment of executive control skills in preschoolers suspected of having ADHD. In this age group, the ACPT-P may be particularly useful in assessing sustained attention and response preparation and may complement behavior rating scales.

    2015-01-01

    The Behavioral Dyscontrol Scale-II (BDS-II) was developed as an improved scoring method to the original BDS, which was designed to evaluate the capacity for independent regulation of behavior and attention. The purpose of this study was to evaluate the factor structure and construct validity of the BDS-II, which had not been adequately re-examined since the development of the new scoring system. In a sample of 164 Veterans with a mean age of 35 years, exploratory factor analysis was used to evaluate BDS-II latent factor structure. Correlations and regressions were used to explore validity against 22 psychometrically sound neurocognitive measures across seven neurocognitive domains of sensation, motor output, processing speed, attention, visual-spatial reasoning, memory, and executive functions. Factor analysis found a two-factor solution for this sample which explained 41% of the variance in the model. Validity analyses found significant correlations among the BDS-II scores and all other cognitive domains except sensation and language (which was not evaluated). Hierarchical regressions revealed that PASAT performance was strongly associated with all three BDS-II scores; dominant hand Finger Tapping Test was also associated with the Total score and Factor 1, and CPT-II Commissions was also associated with Factor 2. These results suggest the BDS-II is both a general test of cerebral functioning, and a more specific test of working memory, motor output, and impulsivity. The BDS-II may therefore show utility with younger populations for measuring frontal lobe abilities and might be very sensitive to neurological injury.

    2015-12-01

    This article presents information about the construct validity and reliability of a new teacher self-report measure of classroom instructional and behavioral practices (the Classroom Strategies Scales-Teacher Form; CSS-T). The theoretical underpinnings and empirical basis for the instructional and behavioral management scales are presented. Information is provided about the construct validity, internal consistency, test-retest reliability, and freedom from item-bias of the scales. Given previous investigations with the CSS Observer Form, it was hypothesized that internal consistency would be adequate and that confirmatory factor analyses (CFA) of CSS-T data from 293 classrooms would offer empirical support for the CSS-T's Total, Composite and subscales, and yield a similar factor structure to that of the CSS Observer Form. Goodness-of-fit indices of χ2/df, Root Mean Square Error of Approximation, Goodness of Fit Index, and Adjusted Goodness of Fit Index suggested satisfactory fit of proposed CFA models whereas the Comparative Fit Index did not. Internal consistency estimates of .93 and .94 were obtained for the Instructional Strategies and Behavioral Strategies Total scales respectively. Adequate test-retest reliability was found for instructional and behavioral total scales (r = .79, r = .84, percent agreement 93% and 93%). The CSS-T evidences freedom from item bias on important teacher demographics (age, educational degree, and years of teaching experience). Implications of results are discussed.

    The fundamental psychometric properties of the subscales found in the Static-2002R, an actuarial measure of sexual recidivism risk, were evaluated in the current study. Namely, the reliability, concurrent and construct validity, and factor structure of the Static-2002R subscales were examined with a sample of 372 adult male sex offenders. In addition to using validated measures of sexual violence risk to examine concurrent validity, construct-related measures taken from extant risk measures and psychometric tests were correlated with three of the subscales to assess overall construct validity. Moderate support was found for the reliability of the Static-2002R. The concurrent and construct validity of the General Criminality, Persistence of Sexual Offending, and Deviant Sexual Interest subscales were supported. Generally, these findings further support the Static-2002R as a valid sex offender risk appraisal instrument that encompasses multiple distinct, clinically relevant, risk domains.

  8. Construct validity-Current issues and recommendations for future hand hygiene research.

    PubMed

    Neo, Jun Rong Jeffrey

    2017-03-10

    Health care-associated infection is a leading cause of morbidity and mortality. Hand hygiene is widely regarded as an effective prevention strategy. Often, hand hygiene research is designed and conducted by health care practitioners who may lack formal training in research methods, particularly in the area of social science. In a research context, a construct is a concept that can be measured or observed in some way. A construct can be directly or indirectly measured. For example, height can be directly measured by centimeters, whereas depression can be indirectly measured by a scale of 20 items. Every construct needs to be operationalized by measure(s) to make it a variable. Hence, construct validity refers to the degree of fit between the construct of interest and its operational measure. However, issues with construct validity often weaken the translation from construct to measure(s). This article will (1) describe the common threats to construct validity pertaining to hand hygiene research, (2) identify practical limitations in current research design, and (3) provide recommendations to improve construct validity in future hand hygiene research. By understanding how construct validity may affect hand hygiene research design, there is great potential to improve the validity of future hand hygiene research findings.

    2015-01-01

    This article describes the development and validation of the Multiracial Experiences Measure (MEM): a new measure that assesses uniquely racialized risks and resiliencies experienced by individuals of mixed racial heritage. Across two studies, there was evidence for the validation of the 25-item MEM with 5 subscales including Shifting Expressions, Perceived Racial Ambiguity, Creating Third Space, Multicultural Engagement, and Multiracial Discrimination. The 5-subscale structure of the MEM was supported by a combination of exploratory and confirmatory factor analyses. Evidence of criterion-related validity was partially supported with MEM subscales correlating with measures of racial diversity in one’s social network, color-blind racial attitude, psychological distress, and identity conflict. Evidence of discriminant validity was supported with MEM subscales not correlating with impression management. Implications for future research and suggestions for utilization of the MEM in clinical practice with multiracial adults are discussed. PMID:26460977

    2016-03-01

    Waste generated in construction and demolition processes comprised around 50% of the solid waste in South Korea in 2013. Many cases show that design validation based on building information modeling (BIM) is an effective means to reduce the amount of construction waste since construction waste is mainly generated due to improper design and unexpected changes in the design and construction phases. However, the amount of construction waste that could be avoided by adopting BIM-based design validation has been unknown. This paper aims to estimate the amount of construction waste prevented by a BIM-based design validation process based on the amount of construction waste that might be generated due to design errors. Two project cases in South Korea were studied in this paper, with 381 and 136 design errors detected, respectively during the BIM-based design validation. Each design error was categorized according to its cause and the likelihood of detection before construction. The case studies show that BIM-based design validation could prevent 4.3-15.2% of construction waste that might have been generated without using BIM.

    2009-01-01

    There is a current and pressing need for a test bed of electronic medical records (EMRs) to insure consistent development, validation and verification of public health related algorithms that operate on EMRs. However, access to full EMRs is limited and not generally available to the academic algorithm developers who support the public health community. This paper describes a set of algorithms that produce synthetic EMRs using real EMRs as a model. The algorithms were used to generate a pilot set of over 3000 synthetic EMRs that are currently available on CDC’s Public Health grid. The properties of the synthetic EMRs were validated, both in the entire aggregate data set and for individual (synthetic) patients. We describe how the algorithms can be extended to produce records beyond the initial pilot data set. PMID:23569572

  17. Racial groups and test fairness, considering history and construct validity.

    Newman, Daniel A; Hanges, Paul J; Outtz, James L

    2007-12-01

    According to Helms, "test fairness" is defined as "removal from test scores of systematic variance attributable to experiences of racial or cultural socialization." Some of Helms's reasoning is based on earlier work, which recommended that racial group or category variables be replaced entirely with individual-level constructs, to reflect racial socialization experiences that vary within racial groups. Treatment of the test fairness issue--a social and political issue--will benefit from explicitly considering historical events that contributed to group-level race differences. In light of this history, D. A. Newman et al suggest (a) retaining a group-level conceptualization of race/racial socialization and also (b) focusing on criterion-irrelevant variance in test scores that is attributable to race.

    2014-04-01

    This study examined the reliability and validity of a Turkish version for the Marital Dispositional Forgiveness Scale (MDFS). 104 married couples (M age = 36.6 yr., SD = 9.4) living in Turkey completed the Turkish versions of the MDFS and the Relationship Assessment Scale (RAS). Cronbach's coefficients a for negative dimension (wives = .82, husbands = .80) and positive dimension (wives = .80, husbands = .79) were adequate. A correlation between the MDFS and RAS scores indicated significant associations, stronger for the positive dimension than the negative dimension, supporting the external validity of the MDFS.

    2015-01-01

    Social interactions have gained increasing importance, both as an outcome and as a possible mediator in psychotherapy research. Still, there is a lack of adequate measures capturing relational aspects in multi-person settings. We present a new measure to assess relevant dimensions of quality of relationships and collective efficacy regarding interpersonal interactions in diverse personal and professional social systems including couple partnerships, families, and working teams: the EVOS. Theoretical dimensions were derived from theories of systemic family therapy and organizational psychology. The study was divided in three parts: In Study 1 (N = 537), a short 9-item scale with two interrelated factors was constructed on the basis of exploratory factor analysis. Quality of relationship and collective efficacy emerged as the most relevant dimensions for the quality of social systems. Study 2 (N = 558) confirmed the measurement model using confirmatory factor analysis and established validity with measures of family functioning, life satisfaction, and working team efficacy. Measurement invariance was assessed to ensure that EVOS captures the same latent construct in all social contexts. In Study 3 (N = 317), an English language adaptation was developed, which again confirmed the original measurement model. The EVOS is a theory-based, economic, reliable, and valid measure that covers important aspects of social relationships, applicable for different social systems. It is the first instrument of its kind and an important addition to existing measures of social relationships and related outcome measures in therapeutic and other counseling settings involving multiple persons.

    This study tested the psychometric properties of the WHOQOL-Bref by examining its construct validity, predictive validity and reliability in a psychiatric sample. The sample consisted of 403 participants recruited from mental health care facilities. Construct validity was assessed through confirmatory factor analysis (CFA) and item-domains correlations. Predictive validity was evaluated via multiple regressions. Internal consistency was analyzed by using Cronbach's alpha. Results from CFA second-order hierarchical model and item-domain correlational analyses supported the construct validity of the WHOQOL-Bref. A 5-domain model (psychological, physical, social relationships, environment and level of independence) demonstrated good-fit and adequate internal consistency. Multiple regression analyses of the domains with overall quality of life (QOL), general health and general QOL were supportive of predictive validity. This study found support for the multidimensionality of the WHOQOL-Bref which demonstrated appropriate properties for the assessment of QOL in psychiatric inpatients and outpatients. Thus, a valuable tool to be incorporated as part of the routine clinical evaluation, monitoring and an important indicator of treatment outcome and research. Our findings suggest a conceptual distinction between the physical domain and level of independence domain in this short version of the WHOQOL, as proposed by the WHOQOL-100.

    Knowlden, Adam P; Sharma, Manoj; Nahar, Vinayak K

    The purpose of this article was to use the multitheory model of health behavior change in predicting adequate sleep behavior in college students. A valid and reliable survey was administered in a cross-sectional design (n = 151). For initiation of adequate sleep behavior, the construct of behavioral confidence (P < .001) was found to be significant and accounted for 24.4% of the variance. For sustenance of adequate sleep behavior, changes in social environment (P < .02), emotional transformation (P < .001), and practice for change (P < .001) were significant and accounted for 34.2% of the variance.

    The objective of the present study was to examine the dimensionality, reliability, and construct validity of the Five Facet Mindfulness Questionnaire (FFMQ) in three Spanish samples using structural equation modeling (SEM). Pooling the FFMQ data from 3 Spanish samples (n = 1191), we estimated the fit of two competing models (correlated five-factor vs. bifactor) via confirmatory factor analysis. The factorial invariance of the best fitting model across meditative practice was also addressed. The pattern of relationships between the FFMQ latent dimensions and anxiety, depression, and distress was analyzed using SEM. FFMQ reliability was examined by computing the omega and omega hierarchical coefficients. The bifactor model, which accounted for the covariance among FFMQ items with regard to one general factor (mindfulness) and five orthogonal factors (observing, describing, acting with awareness, non-judgment, and non-reactivity), fit the FFMQ structure better than the correlated five-factor model. The relationships between the latent variables and their manifest indicators were not invariant across the meditative experience. Observing items had significant loadings on the general mindfulness factor, but only in the meditator sub-sample. The SEM analysis revealed significant links between mindfulness and symptoms of depression and stress. When the general factor was partialled out, the acting with awareness facet did not show adequate reliability. The FFMQ shows a robust bifactor structure among Spanish individuals. Nevertheless, the Observing subscale does not seem to be adequate for assessing mindfulness in individuals without meditative experience. PMID:25914664

    Frederick, Richard I; Bowden, Stephen C

    2009-01-01

    This study uses a new method to summarize diagnostic validity information to explore which constructs are captured by malingering tests. The Test Validation Summary applies mixed-groups validation to investigate the meaning of test constructs and to estimate test classification characteristics when test validation groups are not "pure" criterion groups (ie, "compliant" vs "malingering"), but members have variable probability of malingering. The method permits the use of tests with relatively low validity to validate tests of greater validity. In our initial analysis, we argue that the Rey 15-Item Memory Test is best construed as an "intention test" (capturing the intention of testtakers when taking a test) as opposed to an "effort test." Using the Test Validation Summary and mixed-groups validation, we demonstrate that as an indicator of "intention to feign cognitive impairment," the Rey 15-Item Memory Test has estimated false-positive rate (FPR) = 0.02 and true-positive rate (TPR) = 0.57. We then explore the meaning of failure on the Word Memory Test (WMT), which uses a dichotomous classification of performance as valid or invalid. Although the WMT is commonly referred to as an "effort test," we argue that it likely captures both "intention" and "effort" but collapses this information into a single dichotomous classification of symptom validity. We demonstrate that, as a result of this dichotomous classification process, the WMT likely has a problematic FPR. In our analysis of previously published WMT data, the WMT FPR is estimated at 0.12 when there is no predisposition to perform poorly but rises dramatically and unrealistically as the predisposition to perform poorly increases. We compare these findings to those of the Validity Indicator Profile (VIP), which captures both intent and effort to classify 4 different sorts of response styles in cognitive testing. In our analyses, the VIP demonstrates that FPR = 0 and TPR = 0.86 when the construct being measured is

    Measuring readiness to exercise, or exercise stage of change (ESOC), is an important first step when counseling adults about exercise. However, minimal construct validity testing of ESOC measures has been reported. With a sample of 95 adults, we estimated the construct validity of four ESOC measures with commonly used response formats (true/false, ladder, 5 choice, interview). Participants completed all four ESOC measures in random order as well as six validation measures: physical activity performed, exercise self-efficacy, decisional balance pros and cons, and behavioral and experiential processes of change. Few participants were in the earliest stage of change. The true/false measure demonstrated the strongest validity. Further studies are needed in diverse samples with more representation across the stages of change.

    Atheoretical measure purification may lead to construct deficient measures. The purpose of this paper is to provide a theoretically driven procedure for the development and empirical validation of symmetric component measures of multidimensional constructs. Particular emphasis is placed on establishing a formalized three-step procedure for achieving a posteriori content validity. Then the procedure is applied to development and empirical validation of two symmetrical component measures of market orientation, customer orientation and competitor orientation. Analysis suggests that average variance extracted is particularly critical to reliability in the respecification of multi-indicator measures. In relation to this, the results also identify possible deficiencies in using Cronbach alpha for establishing reliable and valid measures.

  8. The role of language in ethnic identity measurement: a multitrait-multimethod approach to construct validation.

    PubMed

    2009-08-01

    The authors focused on the role of language use in measuring ethnic identity. They demonstrated the construct validity of a 3-dimensional measure and examined potential biases introduced by alternative methods such as constant sum scale. Their findings support the distinction between the 3 subdimensions of language use (English use in family, in media consumption, and while shopping). The authors found evidence of discriminant validity. By using 3 approaches to construct validity, they found that the support for discriminant validity strengthens the discriminant and convergent properties of the instrument. Findings concerning method effects were less obvious. If the traditional multitrait-multimethod approach indicates no method effects, more stringent approaches (e.g., analysis of variance and correlated uniqueness approach) indicate the presence of limited method effects. The authors provide implications regarding measurement of ethnic identity.

    Objective To develop a fatigue assessment scale and test its reliability and validity for commercial construction workers. Methods Using a two-phased approach, we first identified items for the development of a Fatigue Assessment Scale for Construction Workers (FASCW) through review of existing scales in the scientific literature, key informant interviews (n=11) and focus groups (3 groups with 6 workers each) with construction workers. The second phase included assessment for the reliability, validity and sensitivity of the new scale using a repeated-measures study design with a convenience sample of construction workers (n=144). Results Phase one resulted in a 16-item preliminary scale that after factor analysis yielded a final 10-item scale with two sub-scales (“Lethargy” and “Bodily Ailment”).. During phase two, the FASCW and its subscales demonstrated satisfactory internal consistency (alpha coefficients were FASCW (0.91), Lethargy (0.86) and Bodily Ailment (0.84)) and acceptable test-retest reliability (Pearson Correlations Coefficients: 0.59–0.68; Intraclass Correlation Coefficients: 0.74–0.80). Correlation analysis substantiated concurrent and convergent validity. A discriminant analysis demonstrated that the FASCW differentiated between groups with arthritis status and different work hours. Conclusions The 10-item FASCW with good reliability and validity is an effective tool for assessing the severity of fatigue among construction workers. PMID:25603944

    This study establishes the validity of the Prison Inmate Inventory for use among female inmates (N = 628). Contrast groups were used to establish construct validity; negative binomial regression analysis was used to confirm predictive validity. Female inmates who were arrested at a younger age demonstrated more severe problems with violence, antisocial traits, distress, adjustment to prison life, and judgment. Results from the negative binomial analysis revealed that inmate risk (low and severe) predicted expected counts of probation revocations, parole revocation, and escape attempts. Expected counts were not related to race/ethnicity in this sample.

    2016-01-01

    Background: Given that validity is the baseline of psychological assessments, there is a need to provide evidence-based data for construct validity of such scales to advance the clinicians for evaluating psychiatric morbidity in psychiatric and psychosomatic setting. Methods: This comparative cross-sectional study aimed to investigate the construct validity of the Malaysian version of the GHQ-28 and the SCL-90-R. The sample comprised 660 individuals including diabetics, drug dependents, and normal population. The research scales were administered to the participants. Convergent and discriminant validity of both scales were investigated by Confirmatory Factor Analysis (CFA) using AMOS. The Pearson correlation coefficient was utilized to obtain the relationship between the two scales. Results: The internal consistency of the GHQ-28 and SCL-90-R were highly acceptable, and confirmatory factor analysis confirmed the convergent validity of both scales. The results of this study revealed that the construct validity of GHQ-28 was acceptable, whereas discriminant validity of SCL-90-R was not adequate. According to Pearson correlation coefficient the relationships between three common subscales of the GHQ-28 and SCL-90-R were significantly positive; somatization (r=0.671, P<0.01), Anxiety (r=0.728, P<0.01), and Depression (r=0.660, P <0.01). Conclusions: This study replicated the construct of the Malaysian version of GHQ-28, yet failed to support the nine-factor structure of the SCL-90-R. Therefore, multidimensionality of the SCL-90-R as clinical purposes is questionable, and it may be a better unitary measure for assessing and screening mental disorders. Further research need to be carried out to prove this finding. PMID:27252914

    2016-01-01

    Purpose: This study aimed to test the construct validity of an instrument to measure student professional behaviors in entry-level occupational therapy (OT) students in the academic setting. Methods: A total of 718 students from 37 OT programs across the United States answered a self-assessment survey of professional behavior that we developed. The survey consisted of ranking 28 attributes, each on a 5-point Likert scale. A split-sample approach was used for exploratory and then confirmatory factor analysis. Results: A three-factor solution with nine items was extracted using exploratory factor analysis [EFA] (n=430, 60%). The factors were ‘Commitment to Learning’ (2 items), ‘Skills for Learning’ (4 items), and ‘Cultural Competence’ (3 items). Confirmatory factor analysis (CFA) on the validation split (n=288, 40%) indicated fair fit for this three-factor model (fit indices: CFI=0.96, RMSEA=0.06, and SRMR=0.05). Internal consistency reliability estimates of each factor and the instrument ranged from 0.63 to 0.79. Conclusion: Results of the CFA in a separate validation dataset provided robust measures of goodness-of-fit for the three-factor solution developed in the EFA, and indicated that the three-factor model fitted the data well enough. Therefore, we can conclude that this student professional behavior evaluation instrument is a structurally validated tool to measure professional behaviors reported by entry-level OT students. The internal consistency reliability of each individual factor and the whole instrument was considered to be adequate to good. PMID:27246495

    2016-01-01

    Objectives: To test the predictive value and convergent construct validity of a 6-item work functioning screener (WFS-H). Methods: Healthcare workers (249 nurses) completed a questionnaire containing the work functioning screener (WFS-H) and a work functioning instrument (NWFQ) measuring the following: cognitive aspects of task execution and general incidents, avoidance behavior, conflicts and irritation with colleagues, impaired contact with patients and their family, and level of energy and motivation. Productivity and mental health were also measured. Negative and positive predictive values, AUC values, and sensitivity and specificity were calculated to examine the predictive value of the screener. Correlation analysis was used to examine the construct validity. Results: The screener had good predictive value, since the results showed that a negative screener score is a strong indicator of work functioning not hindered by mental health problems (negative predictive values: 94%-98%; positive predictive values: 21%-36%; AUC:.64-.82; sensitivity: 42%-76%; and specificity 85%-87%). The screener has good construct validity due to moderate, but significant (p<.001), associations with productivity (r=.51), mental health (r=.48), and distress (r=.47). Conclusions: The screener (WFS-H) had good predictive value and good construct validity. Its score offers occupational health professionals a helpful preliminary insight into the work functioning of healthcare workers. PMID:27010085

    2013-09-01

    Nutrient profiling classifies individual food products according to their nutrient content. According to the WHO (World Health Organization), validation is a key step in the development of a nutrient profiling system. The aim was to assess the construct validity of five European nutrient profiling systems (Choices, Keyhole, (AFSSA), European Commission (EC) system and FoodProfiler). Construct validity was assessed for each of the five-selected nutrient profiling systems by testing whether healthy foods (that is, identified as eligible by the system) make healthy diets, and unhealthy foods (that is, non-eligible) make unhealthy diets, using diet modeling. The AFSSA, EC and FoodProfiler systems were identified as valid, but differences in their levels of permissiveness suggested some misclassified food products. The two other systems failed the construct validity assessment. Among these three systems, the EC system is the less demanding in terms of nutritional information, it would, therefore, be the easiest to implement for regulating nutrition and health claims in Europe.

    2009-06-01

    This study tested the concurrent and construct validity of a newly developed OMNI-Kayak Scale, testing 8 male kayakers who performed a flatwater load-incremented "shuttle" test over a 500-m course and 3 estimation-production trials over a 1,000-m course. Velocity, blood lactate concentration, heart rate, and rating of perceived exertion (RPE), using the OMNI-Kayak RPE Scale and the Borg 6-20 Scale were recorded. OMNI-Kayak Scale RPE was highly correlated with velocity, the Borg 6-20 Scale RPE, blood lactate, and heart rate for both load-incremented test (rs = .87-.96), and estimation trials (rs = .75-.90). There were no significant differences among velocities, heart rate and blood lactate concentration between estimation and production trials. The OMNI-Kayak RPE Scale showed concurrent and construct validity in assessing perception of effort in flatwater kayaking and is a valid tool for self-regulation of exercise intensity.

    2015-01-01

    Three studies assessed the construct of pathological video game use and tested its predictive validity. Replicating previous research, Study 1 produced evidence of convergent validity in 8th and 9th graders (N = 607) classified as pathological gamers. Study 2 replicated and extended the findings of Study 1 with college undergraduates (N = 504). Predictive validity was established in Study 3 by measuring cue reactivity to video games in college undergraduates (N = 254), such that pathological gamers were more emotionally reactive to and provided higher subjective appraisals of video games than non-pathological gamers and non-gamers. The three studies converged to show that pathological video game use seems similar to other addictions in its patterns of correlations with other constructs. Conceptual and definitional aspects of Internet Gaming Disorder are discussed. PMID:26694472

    The dimensionality of the Hospital Anxiety and Depression Scale (HADS) is a current source of controversy among experts. The present study integrates a solid theoretical framework (Clark & Watson's, 1991, tripartite theory) and a fine-grained methodological approach (structural equation modeling; SEM) to examine the dimensionality and construct validity of the HADS in fibromyalgia (FM) patients. Using the HADS data of 269 Spanish patients with FM, we estimated the cross-sectional and, for the first time, longitudinal fit (autoregressive model) of 2 competing models (oblique 2-factor vs. bifactor) via confirmatory factor analysis. The pattern of relationships between the HADS latent dimensions and positive and negative affect (PA and NA) was analyzed using SEM. HADS reliability was assessed by computing the omega and omega hierarchical coefficients. The bifactor model, which accounted for the covariance among HADS items with regard to 1 general factor (psychological distress) and 2 specific factors (depression and anxiety), described the HADS structure better than the original oblique 2-factor model during both study periods. All latent dimensions of the bifactor model were temporally stable. The SEM analysis revealed a significant link between psychological distress and NA as well as between depression and low PA. Only the general factor of psychological distress showed adequate reliability. In conclusion, the HADS shows a clear bifactor structure among FM patients. Our results indicate that it is not recommendable to compute anxiety and depression scores separately because anxiety variance is tapped primarily by the broader construct of psychological distress, and both specific dimensions show low reliability.

  14. Thwarted Belongingness and Perceived Burdensomeness: Construct Validity and Psychometric Properties of the Interpersonal Needs Questionnaire

    PubMed Central

    2012-01-01

    The present study examines the psychometric properties and construct validity of scores derived from the Interpersonal Needs Questionnaire (INQ) using latent variable modeling with five independent samples varying in age and level of psychopathology. The INQ was derived from the Interpersonal Theory of Suicide and was developed to measure thwarted belongingness and perceived burdensomeness—both proximal causes of desire for suicide. Results support that thwarted belongingness and perceived burdensomeness are distinct, but related constructs and that they can be reliably measured. Further, multiple group analyses were consistent with invariance for younger vs. older adults and non-clinical versus clinical populations thereby supporting the relevance of these constructs to diverse populations. Finally, both constructs demonstrated convergent associations with related interpersonal constructs—including loneliness and social support for belongingness and social worth and death ideation for burdensomeness—as well as prospective associations with suicidal ideation.

    2003-02-01

    The construct validity of developmental ratings of managerial performance was assessed by using 2 data sets, each based on a different 360 degrees rating instrument. Specifically, the authors investigated the nature of the constructs measured by developmental ratings, the structural relationships among those constructs, and the generalizability of results across 4 rater perspectives (boss, peer, subordinate, and self). A structure with 4 lower order factors (Technical Skills, Administrative Skills, Human Skills, and Citizenship Behaviors) and 2 higher order factors (Task Performance and Contextual Performance) was tested against competing models. Results consistently supported the lower order constructs, but the higher order structure was problematic, indicating that the structure of ratings is not yet well understood. Multisample analyses indicated few practically significant differences in factor structures across perspectives.

    Joosten, Annette V; Bundy, Anita C

    2008-08-01

    Construct validity of the Motivation Assessment Scale (MAS) (Durand, Crimmins, The Motivation Assessment Scale 1988) was studied using Rasch analysis data from 67 children (246 MASs), with dual diagnosis of autism and intellectual disability or with intellectual disability only. Results failed to support the proposed unidimensional construct or the original 4-factor structure. Some motivators appear to form a unidimensional construct: "to gain attention", "to gain a tangible object", and "to escape". There was evidence that sensory stimulation represents a different construct. Children with intellectual disability were more apt to be motivated by desire to gain a tangible item or attention. Children with the dual diagnoses were more apt to have sensory stimulation or escape from task demand as a motivator for stereotypic and repetitive behavior.

    2015-01-01

    The purpose of this study was to examine the construct validity of the WOrk-reLated Flow inventory (WOLF; Bakker, 2008). This instrument was administered to 711 men and women who were working in Queensland, Australia. The results from the confirmatory factor analysis showed that the WOLF has moderately acceptable construct validity, with the three-factor model being a borderline fit to the data. Tests of the convergent validity of the WOLF yielded satisfactory results. However, the analysis of the discriminant validity of the WOLF showed that the instrument poorly discriminated between work enjoyment and intrinsic work motivation. Follow-up exploratory factor analysis, using recommended procedures for determining the number of factors to extract, revealed a two-factor solution, with the work enjoyment and intrinsic work motivation items loading on the same factor. Drawing on literature on psychological flow and motivation, as well as the findings of the present study, questions are raised over the adequacy of the conceptual basis of the three-factor model of work-related flow, the discriminant validity of the WOLF subscales, and the appropriateness of the wording of several of this measure's items. Using alternative methods and measures to investigate flow in work settings is recommended.

    1999-05-01

    Physiological hyperarousal (PH) is an understudied component of the tripartite model of depression and anxiety. This study contributes to the literature on PH, the tripartite model, and anxiety and its disorders, using data from psychotherapy outpatients (n = 2,448), air force cadets (n = 1,335), and undergraduates (n = 284). Psychometrics and exploratory and confirmatory factor analyses showed that PH is a reliable, cohesive, discriminable, and valid construct. Compared with subjective anxiety, PH was more associated to panic versus mood disordered status, and to panic versus generalized anxiety disordered status. As hypothesized, an aspect of anxiety sensitivity (i.e., fear of body sensations) was particularly related to subjective anxiety in the presence of PH. Results support the PH construct as replicable, valid, and clinically important and support the utility of the tripartite and related models for understanding the relation of depressive and anxious syndromes.

    This study assessed the construct validity of the Relationship Profile Test (RPT; Bornstein & Languirand, 2003) with a substance abuse sample. One hundred-eight substance abuse patients completed the RPT, Experiences in Close Relationships Scale (ECR-SF; Wei, Russell, Mallinckrodt, & Vogel, 2007), Personality Assessment Inventory (PAI; Morey, 1991), and Symptom Checklist-90-Revised (SCL-90-R: Derogatis 1983). Results suggest that the RPT has good construct validity when compared against theoretically related broadband measures of personality, psychopathology and adult attachment. Overall, health hependency was negatively related to measures of psychopathology and insecure attachment, and overdependence was positively related to measures of psychopathology and attachment anxiety. Many of the predictions regarding RPT detachment and the criterion measures were not supported. Implications of these findings are discussed. PMID:26620463

    2015-06-01

    This study sought to evaluate the construct validity of schizoid personality disorder (SZPD) by investigating a sample of 2,619 patients from the Norwegian Network of Personality-Focused Treatment Programs by a variety of statistical techniques. Nineteen patients (0.7%) reached the diagnostic threshold of SZPD. Results from the factor analyses indicated that SZPD consists of three factors: social detachment, withdrawal, and restricted affectivity/ anhedonia. Overall, internal consistency and diagnostic efficiency were poor and best for the criteria that belong to the social detachment factor. These findings pose serious questions about the clinical utility of SZPD as a diagnostic category. On the other hand, the three factors were in concordance with findings from previous studies and with the trait model for personality disorders in DSM-5, supporting the validity of SZPD as a dimensional construct. The authors recommend that SZPD should be deleted as a diagnostic category in future editions of DSM-5.

    2015-01-01

    This study investigated the construct validity of the Scale of Economic Abuse (SEA). Evidence of construct validity was assessed by examining the relationship between the SEA and an economic outcome, financial resources, as perceived by participants. A sample of 93 women with abusive partners were recruited from a domestic violence organization and interviewed 3 times over a period of 4 months. Hierarchical linear modeling was used to examine the relationship between economic abuse and financial resources over time, controlling for the effects of physical and psychological abuse. The findings indicate that baseline economic abuse was significantly related to baseline financial resources, and within-woman change in economic abuse was significantly predicted change in financial resources over time. The findings suggest that the SEA measures what it is intended to measure: an economic dimension of intimate partner abuse that has damaging economic consequences.

    This study sought to replicate and extend Hall and colleagues' (2014) work on developing and validating scales from the Psychopathic Personality Inventory (PPI) to index the triarchic psychopathy constructs of boldness, meanness, and disinhibition. This study also extended Hall et al.'s initial findings by including the PPI Revised (PPI-R). A community sample (n = 240) weighted toward subclinical psychopathy traits and a male prison sample (n = 160) were used for this study. Results indicated that PPI-Boldness, PPI-Meanness, and PPI-Disinhibition converged with other psychopathy, personality, and behavioral criteria in ways conceptually expected from the perspective of the triarchic psychopathy model, including showing very strong convergent and discriminant validity with their Triarchic Psychopathy Measure counterparts. These findings further enhance the utility of the PPI and PPI-R in measuring these constructs.

    Recreational noise exposure and its impact on hearing is a problem to which increasing attention is being paid. In Spanish, it is necessary to have a reliable and valid instrument that is capable of describing the extent of noise exposure. The aim was to create and validate an instrument to determine listening habits and levels of recreational noise exposure in young people. We performed a transversal questionnaire validation study using university students. We assessed the validity of the content and appearance of the "Recreational Hearing Habits Questionnaire" (CHAR in Spanish) through experts' judgment. Then we piloted the administration of semantic adaptation with 30 students. Finally, the instrument was applied to 335 Chilean university students, obtaining with these indicators that demonstrated convergent validity of the construct, criterion and reliability. We used exploratory and confirmatory factor analysis, as well as correlation and agreement tests. It was confirmed that 14 questions in the questionnaire have a good item-test correlation, having also a factorial structure that indicates the existence of three-dimensions. The questionnaire has good internal consistency and convergent validity with the Noise Exposure Questionnaire. In addition, the score obtained in the CHAR is a predictor of the presence of notch at frequencies of 4 kHz in the right ear and 6 kHz in the left. The CHAR is useful for determining listening habits and thereby recreational noise exposure, indicating good psychometric properties.

  5. Dynamic testing in schizophrenia: does training change the construct validity of a test?

    PubMed

    2004-01-01

    Dynamic testing typically involves specific interventions for a test to assess the extent to which test performance can be modified, beyond level of baseline (static) performance. This study used a dynamic version of the Wisconsin Card Sorting Test (WCST) that is based on cognitive remediation techniques within a test-training-test procedure. From results of previous studies with schizophrenia patients, we concluded that the dynamic and static versions of the WCST should have different construct validity. This hypothesis was tested by examining the patterns of correlations with measures of executive functioning, secondary verbal memory, and verbal intelligence. Results demonstrated a specific construct validity of WCST dynamic (i.e., posttest) scores as an index of problem solving (Tower of Hanoi) and secondary verbal memory and learning (Auditory Verbal Learning Test), whereas the impact of general verbal capacity and selective attention (Verbal IQ, Stroop Test) was reduced. It is concluded that the construct validity of the test changes with dynamic administration and that this difference helps to explain why the dynamic version of the WCST predicts functional outcome better than the static version.

    2010-02-01

    Health-related quality of life (HRQOL) estimates can play an important role in patient care by providing information about the patient's perception of impairment and disability and the degree to which the patient tolerates disease manifestations. The 15-item myasthenia gravis quality of life scale (MG-QOL15) is an HRQOL evaluative instrument specific to patients with myasthenia gravis (MG) that was designed to be easy to administer and interpret. In this multicenter study we demonstrate the construct validity of the MG-QOL15 in the practice setting. To assess the construct validity, score distributions were examined for test items in different MG patient groups that represent the clinical spectrum of the disease. For example, patients in remission more frequently scored test items as normal than did patients in other groups. Patients with lower (better) MG composite scores also more frequently scored items as normal than did patients with higher (worse) scores. There was also appropriate correlation between the MG-QOL15 and the other MG-specific scales studied. The study findings shed light on what troubles MG patients. The MG-QOL15 has construct validity in the clinical practice setting and represents an efficient and valuable tool for assessing HRQOL for patients with MG.

    2009-10-01

    Children's success with participating in life depends heavily on intact executive function (EF) skills. The Behavioural Assessment of the Dysexecutive Syndrome for Children (BADS-C) was developed to address the need for a standardised ecologically valid test of children's EF performance. This study aimed to establish the construct validity of the BADS-C in relation to socio-demographic parameters. Participants were 208 Israeli children, aged 8-15 years, who were divided into three age groups (8 years to 9 years and 11 months; 10 years to 11 years and 11 months; 12 to 15 years) and tested with the BADS-C. The older age groups achieved significantly better scores than the younger groups. No significant differences were found between genders in any of the BADS-C scores. Similar results were found for familial socio-economic status and parents' education. Construct validity was demonstrated for the BADS-C by providing a profile for different age groups. Additional studies are needed to examine further the validity and reliability of the BADS-C and the relationships between socio-demographic factors and EF.

    The main objective of this present study is to demonstrate the estimation of validity values and its consistency based on structural equation model. The method of estimation was then implemented to an empirical data in case of the construction the patient loyalty model. In the hypothesis model, service quality, patient satisfaction and patient loyalty were determined simultaneously, each factor were measured by any indicator variables. The respondents involved in this study were the patients who ever got healthcare at Puskesmas in Padang, West Sumatera. All 394 respondents who had complete information were included in the analysis. This study found that each construct; service quality, patient satisfaction and patient loyalty were valid. It means that all hypothesized indicator variables were significant to measure their corresponding latent variable. Service quality is the most measured by tangible, patient satisfaction is the most mesured by satisfied on service and patient loyalty is the most measured by good service quality. Meanwhile in structural equation, this study found that patient loyalty was affected by patient satisfaction positively and directly. Service quality affected patient loyalty indirectly with patient satisfaction as mediator variable between both latent variables. Both structural equations were also valid. This study also proved that validity values which obtained here were also consistence based on simulation study using bootstrap approach.

    Objective To construct and validate markers of vulnerability of women to STDs/HIV, taking into consideration the importance of STDs/HIV. Method Methodological study carried out in three stages: 1) systematic review and identification of elements of vulnerability in the scientific production; 2) selection of elements of vulnerability, and development of markers; 3) establishment of the expert group and validation of the markers (content validity). Results Five markers were validated: no openness in the relationship to discuss aspects related to prevention of STDs/HIV; no perception of vulnerability to STDs/HIV; disregard of vulnerability to STDs/ HIV; not recognizing herself as the subject of sexual and reproductive rights; actions of health professionals that limit women's access to prevention of STDs/HIV. Each marker contains three to eleven components. Conclusion The construction of such markers constituted an instrument, presented in another publication, which can contribute to support the identification of vulnerabilities of women in relation to STDs/HIV in the context of primary health care services. The markers constitute an important tool for the operationalization of the concept of vulnerability in primary health care and to promote inter/multidisciplinary and inter/multi-sectoral work processes.

    Few studies have assessed the construct validity of measures of neighborhood food environment, which remains a major challenge in accurately assessing food access. In this study, we adapted a psychometric tool to examine the construct validity of 4 such measures for 3 constructs. We used 4 food-environment measures to collect objective data from 422 Ontario, Canada, food stores in 2010. Residents' perceptions of their neighborhood food environment were collected from 2,397 households between 2009 and 2010. Objective and perceptual data were aggregated within buffer zones around respondents' homes (at 250 m, 500 m, 1,000 m, and 1,500 m). We constructed multitrait-multimethod matrices for each scale to examine construct validity for the constructs of food availability, food quality, and food affordability. Convergent validity between objective measures decreased with increasing geographic scale. Convergent validity between objective and subjective measures increased with increasing geographic scale. High discriminant validity coefficients existed between food availability and food quality, indicating that these two constructs may not be distinct in this setting. We conclude that the construct validity of food environment measures varies over geographic scales, which has implications for research, policy, and practice.

    Relations between multiple dimensions of self-concept, personality (Big Five), well-being, and academic outcomes (school grades, test scores, coursework selection) for a large (N=4,475) sample of German adolescents support the construct validity of a well-defined, multidimensional set of self-concept factors in relation to personality factors, and vice versa. Confirmatory factor analysis of a German adaptation of the Self Description Questionnaire III demonstrated 17 a priori, reasonably independent self-concept factors (M correlation=.14; SD=.17) that had a highly differentiated pattern of relations with the personality factors and academic outcomes. Consistent with theory and previous research, math and verbal self-concepts were negatively related to each other, and this extreme domain specificity was reflected in the systematic and substantial relations with academic criteria measures. Self-esteem, Big Five, and well-being factors explained only small amounts of variance in academic outcomes and support for their incremental validity after controlling for specific self-concept factors was weak.

    Several researchers have persuasively argued that the most important evidence to consider when assessing construct validity is whether variations in the construct of interest cause corresponding variations in the measures of the focal construct. Unfortunately, the literature provides little practical guidance on how researchers can go about testing this. Therefore, the purpose of this article is to describe how researchers can use video techniques to test whether their scales measure what they purport to measure. First, we discuss how researchers can develop valid manipulations of the focal construct that they hope to measure. Next, we explain how to design a study to use this manipulation to test the validity of the scale. Finally, comparing and contrasting traditional and contemporary perspectives on validation, we discuss the advantages and limitations of video-based validation procedures.

    Inadequately adopted fundamental movement skills (FMS) in early childhood may have a negative impact on the motor performance in later life (Gallahue and Ozmun, 2005). The need for an efficient FMS testing in Physical Education was recognized. The aim of this paper was to construct and validate a new FMS test for 8 year old children. Ninety-five 8 year old children were used for the testing. A total of 24 new FMS tasks were constructed and only the best representatives of movement areas entered into the final test product - FMS-POLYGON. The ICC showed high values for all 24 tasks (0.83-0.97) and the factorial analysis revealed the best representatives of each movement area that entered the FMS-POLYGON: tossing and catching the volleyball against a wall, running across obstacles, carrying the medicine balls, and straight running. The ICC for the FMS-POLYGON showed a very high result (0.98) and, therefore, confirmed the test’s intra-rater reliability. Concurrent validity was tested with the use of the “Test of Gross Motor Development” (TGMD-2). Correlation analysis between the newly constructed FMS-POLYGON and the TGMD-2 revealed the coefficient of -0.82 which indicates a high correlation. In conclusion, the new test for FMS assessment proved to be a reliable and valid instrument for 8 year old children. Application of this test in schools is justified and could play an important factor in physical education and sport practice. Key points All 21 newly constructed tasks demonstrated high intra-rater reliability (0.83-0.97) in FMS assessment. High reliability was also noted in the FMS-POLYGON test (0.98). A high correlation was found between the FMS-POLYGON and TGMD-2 which is a confirmation of the new test’s concurrent validity. The research resolved the problem of long and detailed FMS assessment by adding a new dimension using quick and effective norm-referenced approach but also covering all the most important movement areas.

    The oral Symbol Digit Modalities Test (SDMT) has been recommended to assess cognition for multiple sclerosis (MS) patients. However, the lack of adequate normative data has limited its clinical utility. Recently published regression-based norms may resolve this limitation but, because these norms were derived from a relatively small sample, their stability is unclear. We aimed to evaluate the stability of regression-based SDMT norms by comparing existing norms to a cross-validation dataset. First, regression-based normative data were created from a similarly-sized, independent, control sample (n = 94). Next the original and cross-validation norms were compared for equivalency, management of demographic influences, construct validity, and impairment classification rates in a mildly affected MS sample (n = 70). Lastly, similar comparisons were made for a large, representative MS clinic sample (n = 354). We found construct validity and management of demographic influences were equivalent for the two sets of regression-based norms but lower T-scores were obtained using the original dataset, resulting in discrepancies in impairment classification. In conclusion, regression-based norms for the oral SDMT attenuate demographic influences and possess adequate construct validity. However, norms generated using small samples may yield unreliable classification of cognitive impairment. Larger, representative databases will be necessary to improve the clinical utility of regression-based norms.

    The Neurological Outcome Scale for Traumatic Brain Injury (NOS-TBI) is a measure adapted from the National Institutes of Health Stroke Scale (NIHSS), and is intended to capture essential neurological deficits impacting individuals with traumatic brain injury (TBI) (see Wilde et al., 2010 ). In the present study we evaluate the measure's construct validity via comparison with a quantified neurological examination performed by a neurologist. Spearman rank-order correlation between the NOS-TBI and the neurological examination was rho = 0.76, p < 0.0001, suggesting a high degree of correspondence (construct validity) between these two measures of neurological function. Additionally, items from the NOS-TBI compared favorably to the neurological examination items, with correlations ranging from 0.60 to 0.99 (all p < 0.0001). On formal neurological examination, some degree of neurological impairment was observed in every participant in this cohort of individuals undergoing rehabilitation for TBI, and on the NOS-TBI neurological impairment was evident in all but one participant. This study documents the presence of measurable neurological sequelae in a sample of patients with TBI in a post-acute rehabilitation setting, underscoring the need for formal measurement of the frequency and severity of neurological deficits in this population. The results suggest that the NOS-TBI is a valid measure of neurological functioning in patients with TBI.

    This study assessed the psychometric properties of the SF-36 questionnaire in a sample of 4344 Peruvian people aged 15 to 64 years. Internal consistency reliability was estimated using Cronbach's α coefficient, construct validity by known-groups comparison defined with respect to key sociodemographic characteristics, and factor structure by confirmatory factor analysis (CFA) at item level. Cronbach's α coefficient for the full questionnaire was 0.82 and ranged between 0.66 and 0.92 by scales. The 8 scales discriminated well between sexes, age, and socioeconomic groups. CFA showed that a model with 8 first-order factors and 2 second-order factors (namely, physical and mental health) was a feasible representation of the SF-36 factor structure and had better fit to data than alternative factor structures. The SF-36 showed appropriate psychometric properties regarding internal consistency, construct validity, and factor structure when tested in Peru. Future studies should focus on testing other psychometric properties of the SF-36, such as convergent and discriminant validity, test-retest reliability, and sensitivity to change.

    Purpose: This study investigated the psychometric properties of two oral language measures that are commonly used for diagnostic purposes with school age children who have language impairments. Methods: 216 children with SLI were assessed with the Test of Language Development-Primary, 3rd edition (TOLD-P:3) and the Comprehensive Assessment of Spoken Language (CASL) within a three-month period. The concurrent and construct validity of these two published tests were explored through correlation analysis and principle component factor analysis. Results: The TOLD-P:3 Spoken Language Quotient and CASL Core Composite scores were found to have an inter-test correlation value of r = .596 within this sample, and a paired samples t-test revealed a statistically significant difference between these scores. Principle component factor analyses revealed a two factor structure solution for the TOLD-P:3, while data from the CASL supported a single factor model. Conclusions: Analyses of assessment measure performance data from a sample of school age children with specific language impairment revealed concurrent validity values and construct validity patterns that differed from those found in the norming samples as cited in examiner’s manuals. Implications for practice patterns and future research are discussed. PMID:21930614

    Background The construct, convergent, discriminant, and predictive validity of Learning Potential (LP) was evaluated in a trial of cognitive remediation for adults with schizophrenia-spectrum disorders. LP utilizes a dynamic assessment approach to prospectively estimate an individual's learning capacity if provided the opportunity for specific related learning. Methods LP was assessed in 75 participants at study entry, of whom 41 completed an eight-week cognitive remediation (CR) intervention, and 22 received treatment-as-usual (TAU). LP was assessed in a “test-train-test” verbal learning paradigm. Incremental predictive validity was assessed as the degree to which LP predicted memory skill acquisition above and beyond prediction by static verbal learning ability. Results Examination of construct validity confirmed that LP scores reflected use of trained semantic clustering strategy. LP scores correlated with executive functioning and education history, but not other demographics or symptom severity. Following the eight-week active phase, TAU evidenced little substantial change in skill acquisition outcomes, which related to static baseline verbal learning ability but not LP. For the CR group, LP significantly predicted skill acquisition in domains of verbal and visuospatial memory, but not auditory working memory. Furthermore, LP predicted skill acquisition incrementally beyond relevant background characteristics, symptoms, and neurocognitive abilities. Conclusions Results suggest that LP assessment can significantly improve prediction of specific skill acquisition with cognitive training, particularly for the domain assessed, and thereby may prove useful in individualization of treatment.

    Mealtime satisfaction is an important component of quality of life (QOL) in residential care, yet there currently is no self-administered tool described in the literature. The purpose of this study is to investigate internal and test-retest reliability, and construct validity of a mealtime satisfaction questionnaire (MSQ) designed for residential care, more specifically retirement homes. A 15-item MSQ was developed and eligible participants from four retirement homes (n = 749) were invited to participate. The participation rate was 24% and the median age was 88 years for respondents. The internal consistency of the MSQ was high (Cronbach Alpha = 0.83) and the test-retest reliability was also high (Intraclass coefficient = 0.91, P < 0.01). The MSQ was associated with a valid and reliable QOL instrument for older adults (Mann Whitney Test = 1595.5, P < 0.01). The MSQ is reliable and is content and construct valid. QOL can be enriched by improving mealtime satisfaction in retirement homes.

    Compulsive buying is a relatively new psychopathological concept and very few data are currently available regarding the prevalence and validity of compulsive buying disorder. In this cross-sectional study, we establish the prevalence of compulsive buying disorder in shopping mall visitors and explore the construct validity of the concept using the revised version of the Edwards Compulsive Buying Scale in 1441 shopping mall visitors looking at shopping habits, current substance use (smoking, alcohol and illicit drug) and various psychological characteristics. Overall, 8.7% (95% CI: 7.3-10.3) of our sample was classified as having a compulsive buying disorder. Compulsive buyers were younger, less educated and more likely to be female than non-compulsive buyers. They were also more likely to have used licit and illicit substances. Compulsive buyers also reported higher levels of impulsivity and obsessive-compulsive symptoms, lower levels of well-being and self-esteem and more psychological distress. Finally, compulsive buyers were five times more likely to meet criteria for borderline personality disorder than non-compulsive buyers. Compulsive buying is a frequent disorder in shopping mall visitors and is associated with important and robust indicators of psychopathology thus supporting the validity of the construct.

    Objective Previous studies of the Depression and Somatic Symptoms Scale (DSSS), a free scale, have been based on the classical test theory, and the construct validity and dimensionality of the DSSS are as yet uncertain. The aim of this study was to use Mokken scale analysis (MSA) to assess the dimensionality of the DSSS. Methods A sample of 214 psychiatric outpatients with mood and anxiety disorders were enrolled at a medical center in Taiwan (age: mean [SD] =38.3 [10.5] years; 63.1% female) and asked to complete the DSSS. MSA was used to assess the dimensionality of the DSSS. Results All 22 items of the DSSS formed a moderate unidimensional scale (Hs=0.403), supporting its construct validity. The DSSS was divided into 4 subscales (Hs ranged from 0.35 to 0.67), including a general somatic scale (GSS), melancholic scale (MS), muscular pain scale (MPS), and chest symptom scale (CSS). The GSS is a weak reliable Mokken scale; the other 3 scales are strong reliable Mokken scales. Conclusion The DSSS is a psychometrically sound measure of depression and somatic symptoms in adult psychiatric outpatients with depression or anxiety. The summed score of the DSSS and its 4 subscales are valid statistics. Further research is required for replication of the 4 subscales of the DSSS. PMID:28182138

    This study involved the design and validation of a new Lyme disease risk assessment instrument. The study was funded in part by a research grant from the American Health Information Management Association (AHIMA) Foundation on Research and Education (FORE). The resulting instrument measured theoretical constructs such as attitudes, behaviors, beliefs, skills, and knowledge relative to Lyme disease. The survey assessment tool is described here, and the tool development process, the validation and reliability process, and results are presented. The assessment tool was created by using a standard instrument development process that first involved constructing possible items (questions) based on several health behavior theories and known health risk behaviors. These items were then further refined by using focus groups, a small pilot study, factor analysis, and a large-scale pilot study. Validity and reliability indices were established with a test-retest reliability coefficient of .66, and finally the tool was used among a population living in a Lyme-disease-endemic area. Cronbach's alpha coefficients of .737 for behavioral items, .573 for cognitive items, and .331 for environmental items were established. PMID:18066379

    Although the Defense Mechanism Test (DMT) has been in use for almost half a century, there are still quite contradictory views about whether it is a reliable instrument, and if so, what it really measures. Thus, based on data from 39 female students, we first examined DMT inter-coder reliability by analyzing the agreement among trained judges in their coding of the same DMT protocols. Second, we constructed a "parallel" photographic picture that retained all structural characteristic of the original and analyzed DMT parallel-test reliability. Third, we examined the construct validity of the DMT by (a) employing three self-report defense-mechanism inventories and analyzing the intercorrelations between DMT defense scores and corresponding defenses in these instruments, (b) studying the relationships between DMT responses and scores on trait and state anxiety, and (c) relating DMT-defense scores to measures of self-esteem. The main results showed that the DMT can be coded with high reliability by trained coders, that the parallel-test reliability is unsatisfactory compared to traditional psychometric standards, that there is a certain generalizability in the number of perceptual distortions that people display from one picture to another, and that the construct validation provided meager empirical evidence for the conclusion that the DMT measures what it purports to measure, that is, psychological defense mechanisms.

    High accuracy, geometric complexity and thus high cost of stellarators tend to hinder the advance of stellarator research. Nowadays, new manufacturing methods might be developed for the production of small and middle-size stellarators. The methods should demonstrate advantages with respect common fabrication methods, like casting, cutting, forging and welding, for the construction of advanced highly convoluted modular stellarators. UST2 is a small modular three period quasi-isodynamic stellarator of major radius 0.26 m and plasma volume 10 litres being currently built to validate additive manufacturing (3D printing) for stellarator construction. The modular coils are wound in grooves defined on six 3D printed half period frames designed as light truss structures filled by a strong filler. A geometrically simple assembling configuration has been concocted for UST2 so as to try to lower the cost of the device while keeping the positioning accuracy of the different elements. The paper summarizes the construction and assembling concepts developed, the devised positioning methodology, the design of the coil frames and positioning elements and, an initial validation of the assembling of the components.

    The Triarchic model of psychopathy describes this complex condition in terms of distinct phenotypic components of boldness, meanness, and disinhibition. Brief self-report scales designed specifically to index these psychopathy facets have thus far demonstrated promising construct validity. The present study sought to develop and validate scales for assessing facets of the Triarchic model using items from a well-validated existing measure of psychopathy—the Psychopathic Personality Inventory (PPI). A consensus rating approach was used to identify PPI items relevant to each Triarchic facet, and the convergent and discriminant validity of the resulting PPI-based Triarchic scales were evaluated in relation to multiple criterion variables (i.e., other psychopathy inventories, antisocial personality disorder features, personality traits, psychosocial functioning) in offender and non-offender samples. The PPI-based Triarchic scales showed good internal consistency and related to criterion variables in ways consistent with predictions based on the Triarchic model. Findings are discussed in terms of implications for conceptualization and assessment of psychopathy. PMID:24447280

    The purpose of this research was to provide further evidence for the construct validity (i.e., convergent, concurrent, and discriminant validity) of the Prosocial and Antisocial Behaviour in Sport Scale (PABSS), an instrument that has four subscales measuring prosocial and antisocial behaviour toward teammates and opponents. We also investigated test-retest reliability and stability of the PABSS. We conducted three studies using athletes from a variety of team sports. In Study 1, participants (N = 129) completed the PABSS and measures of physical and verbal aggression, hostility, anger, moral identity, and empathy; a sub-sample (n = 111) also completed the PABSS one week later. In Study 2, in addition to the PABSS, participants (N = 89) completed measures of competitive aggressiveness and anger, moral attitudes, moral disengagement, goal orientation, and anxiety. In Study 3, participants (N = 307) completed the PABSS and a measure of social goals. Across the three studies, the four subscales evidenced the hypothesised relationships with a number of variables. Correlations were large between the two antisocial behaviours and small between the two prosocial behaviours. Overall, the findings supported the convergent, concurrent, and discriminant validity of the scale, provided evidence for its test-retest reliability and stability, and suggest that the instrument is a valid and reliable measure of prosocial and antisocial behaviour in sport.

    Since cutoff scores are necessary for differentiating normal cognitive functioning from dementia, the main objective of this study was to establish normative data of the K-T test, a standardized cancellation test. The construct validity of K-T test was also investigated. In total, 2471 cognitively intact elderly subjects from the SU.VI.MAX 2 study were included in the present study. Younger subjects, women and subjects with higher education had a higher number of correct answers and fewer omission errors. Participants made few commission errors and only the educational level was found to have a significant effect. Normative data for correct responses and efficiency were stratified by age, education, and gender. Correlation analysis showed that the K-T test was significantly correlated to validated neuropsychological tests assessing executive functions. This study permits to strengthen the utility of the K-T test to detect impairment of the executive components involved in the task.

    The main purpose of this study is to develop a valid and reliable instrument for measuring the attitudes toward science class of fourth- and fifth-grade students in an Asian school culture. Specifically, the development focused on three science attitude constructs-science enjoyment, science confidence, and importance of science as related to science class experiences. A total of 265 elementary school students in Taiwan responded to the instrument developed. Data analysis indicated that the instrument exhibited satisfactory validity and reliability with the Taiwan population used. The Cronbach's alpha coefficient was 0.93 for the entire instrument indicating a satisfactory level of internal consistency. However, both principal component analysis and parallel analysis showed that the three attitude scales were not unique and should be combined and used as a general "attitudes toward science class" scale. The analysis also showed that there were no gender or grade-level differences in students' overall attitudes toward science class.

    The present study examined the factor structure underlying the Wisconsin Schizotypy Scales and the validity of these dimensions. Confirmatory factor analysis with 6137 nonclinical young adults supported a 2-factor model with positive and negative schizotypy dimensions. As predicted, the schizotypy dimensions were differentially related to psychopathology, personality, and social impairment. Both dimensions were related to schizotypal and paranoid symptoms. Positive schizotypy was uniquely related to psychotic-like experiences, substance abuse, mood disorders, and mental health treatment, whereas negative schizotypy was associated with negative and schizoid symptoms. Both dimensions were associated with poorer overall and social functioning, but negative schizotypy was associated with decreased likelihood of intimate relationships. The findings support the construct validity of a multidimensional model of schizotypy and the use of psychometric inventories to assess these dimensions.

    Objective: We have previously demonstrated that neurological individual findings and patterns can be reliably assessed in the examination of the upper limb and also that they are related to pain, weakness, and/or numbness/tingling. This study aimed to study further aspects of the construct validity of the neurological examination. Methods: Blinded to patient-characteristics, two examiners assessed the function of 16 muscles, the sensibility in 7 territories, and the nerve-mechanosensitivity at 20 locations in 82 upper limbs. Based on anatomical patterns and pre-designed algorithms, one or both examiners rated neuropathy as “possible” or “definite” in 40 limbs and also determined the location( s). We developed and tested hypotheses on anatomically and regionally related locations of nerve afflictions (a selective vulnerability of neurons, double and multiple crush, and a tendency to regional spread) and examined the stability of the internal structure of the constructs in different situations. The interrelations of findings were analyzed by hypothesis testing and factor analyses, and the homogeneity of location profiles was analyzed by a conditional likelihood test. Results: Out of 30 limbs with related locations of neuropathy, the findings of each examiner correlated positively (gamma > 0.35) in 22/25, respectively. The patterns of the interrelations identified by the two examiners were similar, with no evidence of any heterogeneity of location profiles for either examiner. Conclusions: This study supports the validity of the physical examination. However, feasibility of its application requires the demonstration of further aspects of construct validity and a favorable influence on patient-management and/or prevention. PMID:20148172

    Given the current debate over the distinction between subtle and blatant prejudice, this study provides new evidence regarding problems with the construct validity of the Pettigrew and Meertens' Blatant and Subtle Prejudice Scale. To assess these issues, an existing data sample of 896 Chilean participants collected in 2010 was reanalyzed. The main analysis method used was a confirmatory factor analysis. The model that best represented the original theory (a model of two correlated second-order factors) had an improper solution due to the unidentified model. The scale has substantial psychometric problems, and it was not possible to distinguish between subtle and blatant prejudice.

    With the Psychological Capital Questionnaire (PCQ) being the standard measure to assess psychological capital (PsyCap) in the context of organizations, this paper aims to broaden this domain-specific approach by introducing a measure with universal claim. Two studies were conducted to create and validate a German self-report scale (CPC-12) measuring PsyCap. We performed confirmatory factor analyses and correlations with other positive psychological constructs on the data of two German samples (N1 = 321; N2 = 202). The twelve-item CPC-12 exhibits the anticipated factorial structure with a very good model fit and associations to other constructs concur with previous findings with other measures of PsyCap.

    With the aim of advancing the literature on impression management in physical activity settings, we developed a theoretically derived 2 by 2 instrument that was designed to measure different types of context-specific self-presentation motives. Following item generation and expert review (Study 1), the instrument was completed by 206 group exercise class attendees (Study 2) and 463 high school physical education students (Study 3). Our analyses supported the intended factor structure (i.e., reflecting acquisitive-agentic, acquisitive-communal, protective-agentic, and protective-communal motives). We found some support for construct validity, and the self-presentation motives were associated with variables of theoretical and applied interest (e.g., impression motivation and construction, social anxiety, social and achievement goals, efficacy beliefs, engagement). Taken together, the results indicate that the Self-presentation Motives for Physical Activity Questionnaire (SMPAQ) may be useful for measuring various types of self-presentation motives in physical activity settings.

    A wealth of research has underscored the strong relationship between PCL-R scores and recidivism. However, mounting criticism cites the PCL-R's cumbersome administration procedures and failure to adequately measure core features associated with the construct of psychopathy (Skeem, Polaschek, Patrick, & Lilienfeld, 2011). In light of these concerns, this study examined the PPI and the PPI-R, which were designed to measure core personality features associated with psychopathy (Lilienfeld & Andrews, 1996; Lilienfeld & Widows, 2005). Study one examined the PPI relative to the PCL-R and examined its factor structure. The instruments shared few significant correlations and neither the PCL-R nor the PPI significantly predicted recidivism. Study two examined the PPI-R relative to the PCL-R, the PPI, both history of violence and future criminal activity and measure of related constructs. The PPI-R was significantly correlated with measures of empathy and criminal thinking and the factors were related to a history of violence and predicted future violent criminal behavior.

    The purpose of this study is to design and fabricate an anthropopathic abdominal phantom for accuracy evaluation of deformable image registration (DIR) algorithms in adaptive radiation therapy. The constructed deformable organs, including the liver, kidney, spleen and stomach, are made of mixture of polyvinyl chloride (PVC) and softener dioctyl terephthalate, while the rigid structures, i.e. vertebrae, are made of white cement. Relation between the PVC-softener blending ratio and organ CT number is studied, and three-dimensional printing technic is employed to create highly anthropopathic organs in terms of organ shape and density. Detailed steps for phantom construction, landmark point placement and choice of phantom ingredients and construction recipe are introduced. Preliminary results of the mechanical properties of the fabricated organs are also presented. The experimental results indicate that the constructed phantom has satisfactory elastic characteristics and close CT number with corporal organs, and can potentially be applied to simulate real abdominal organ deformation in geometric accuracy validation of DIR algorithms.

    The construct validity of a kinesiophysical Functional Capacity Evaluation (FCE) administered within a worker's compensation context was examined. A cross-sectional study design was employed. Clinical and demographic information on workers' compensation claimants was extracted from a rehabilitation facility's database. Measures of interest were the Isernhagen Work Systems' (Duluth, MN) FCE, the Pain Disability Index (PDI), and a pain visual analogue scale (VAS). A multitrait Pearson correlation matrix was created to observe the pattern of relationships between variables. The sample consisted of 321 subjects with work-related, medically stable low back pain of median duration of 307 days. FCE performance was moderately correlated with the PDI (r = -0.44-0.52) and with the pain VAS (r = 0.34-0.45). Pain intensity was correlated highly with the PDI (r = 0.79). The moderate relationship between FCE and the PDI supports the construct validity of FCE as a functional measure. However, kinesiophysical FCE performance was not unrelated to pain severity ratings as purported.

    The aim of this study was to demonstrate construct validation of the haptic virtual reality (VR) dental simulator and to define expert benchmarking criteria for skills assessment. Thirty-four self-selected participants (fourteen novices, fourteen intermediates, and six experts in endodontics) at one dental school performed ten repetitions of three mode tasks of endodontic cavity preparation: easy (mandibular premolar with one canal), medium (maxillary premolar with two canals), and hard (mandibular molar with three canals). The virtual instrument's path length was registered by the simulator. The outcomes were assessed by an expert. The error scores in easy and medium modes accurately distinguished the experts from novices and intermediates at the onset of training, when there was a significant difference between groups (ANOVA, p<0.05). The trend was consistent until trial 5. From trial 6 on, the three groups achieved similar scores. No significant difference was found between groups at the end of training. Error score analysis was not able to distinguish any group at the hard level of training. Instrument path length showed a difference in performance according to groups at the onset of training (ANOVA, p<0.05). This study established construct validity for the haptic VR dental simulator by demonstrating its discriminant capabilities between that of experts and non-experts. The experts' error scores and path length were used to define benchmarking criteria for optimal performance.

    Neighborhood physical disorder is thought to affect mental and physical health, but it has been difficult to measure objectively and reliably across large geographical areas or multiple locales. Virtual street audits are a novel method for assessing neighborhood characteristics. We evaluated the ecometric properties of a neighborhood physical disorder measure constructed from virtual street audit data. Eleven trained auditors assessed 9 previously validated items developed to capture physical disorder (e.g., litter, graffiti, and abandoned buildings) on 1,826 block faces using Google Street View imagery (Google, Inc., Mountain View, California) dating from 2007-2011 in 4 US cities (San Jose, California; Detroit, Michigan; New York, New York; and Philadelphia, Pennsylvania). We constructed a 2-parameter item response theory scale to estimate latent levels of disorder on each block face and defined a function using kriging to estimate physical disorder levels, with confidence estimates, for any point in each city. The internal consistency reliability of the resulting scale was 0.93. The final measure of disorder was positively correlated with US Census data on unemployment and housing vacancy and negatively correlated with data on owner-occupied housing. These results suggest that neighborhood physical disorder can be measured reliably and validly using virtual audits, facilitating research on possible associations between physical disorder and health.

    The current work sought to operationalize constructs of the triarchic model of psychopathy in chimpanzees (Pan troglodytes), a species well-suited for investigations of basic biobehavioral dispositions relevant to psychopathology. Across three studies, we generated validity evidence for scale measures of the triarchic model constructs in a large sample (N=238) of socially-housed chimpanzees. Using a consensus-based rating approach, we first identified candidate items for the chimpanzee triarchic (CHMP-Tri) scales from an existing primate personality instrument and refined these into scales. In Study 2, we collected data for these scales from human informants (N=301), and examined their convergent and divergent relations with scales from another triarchic inventory developed for human use. In Study 3, we undertook validation work examining associations between CHMP-Tri scales and task measures of approach-avoidance behavior (N=73) and ability to delay gratification (N=55). Current findings provide support for a chimpanzee model of core dispositions relevant to psychopathy and other forms of psychopathology. PMID:26779396

    Objective: The objective of the present study is to contribute towards the validation of the SOC (Sense of Coherence) construct on the basis of data from psychosomatic patients. Method: The study included a total of 1403 patients treated as out-patients or in consultations in the Clinic for Psychosomatic Medicine at the Charité University of Medicine, Berlin, between July 2002 and October 2005. Correlations were tested between the sense of coherence (SOC-L9), sociodemographic variables and the following psychometric instruments: Patient Health Questionnaire (PHQ), Brief COPE, Questionnaire on Self-Efficacy, Optimism and Pessimism (SWOP-K9) and Perceived Stress Questionnaire (PSQ-20). Results: Associations were found between sense of coherence and age, but not with gender. In addition, high sense of coherence was correlated with high self-efficacy, optimism, subjective physical well-being and favourable coping strategies as well as with low perceived stress. Conclusion: The results contribute to the validation of the SOC construct. Future investigations should include longitudinal studies of the precise association between sense of coherence and other psychological variables. PMID:19742290

    There is a need for a brief measure of emotion dysregulation that can be used in large-scale studies. This study evaluated the construct validity of a short, self-report instrument of emotion dysregulation. Subjects (N=2197) were recruited from primary care clinics of an urban public hospital as part of a study of trauma-related risk and resilience. Emotion dysregulation was measured using the Emotion Dysregulation Scale, short version (EDS-short), a12-item self-report measure assessing emotional experiencing, cognition, and behavior. EDS-short was first compared with the Difficulties in Emotion Regulation Scale (DERS). Then, the construct validity of the EDS-short in predicting depression, posttraumatic stress, substance abuse, borderline pathology, suicide attempts, psychiatric hospitalizations, positive affect, and resiliency was assessed. We found a significant positive correlation between EDS-short and DERS. The EDS-short was significantly predictive of higher reported depressive, posttraumatic stress, substance abuse, and borderline symptoms, and lower reported positive affect and resiliency, over and above demographic characteristics and negative affect. Our results demonstrate that the EDS-short is a useful instrument for measuring emotion dysregulation in traumatized populations. A brief measure of emotion dysregulation is critical as the field moves forward in studying the wide ranging negative effects of emotion dysregulation across psychiatric disorders and outcomes.

    The purpose of this study was to construct and validate a “Perceived Physical Literacy Instrument” (PPLI) for physical education teachers. Based on literature review and focus group interviews, an 18-item instrument was developed for the initial tests. This self-report measure, using a 5-point Likert scale, formed the PPLI and was administered to 336 physical education teachers in Hong Kong. The sample was randomly split, and exploratory and confirmatory factor analyses resulted in a 9-item, 3-factor scale. Exploratory factor analysis (EFA) item loadings ranged from 0.69 to 0.87, and Cronbach’s alpha ranged from 0.73 to 0.76. Confirmatory factor analysis (CFA) showed that the construct demonstrated good fit to the model. The PPLI thus appeared to be reliable and valid to measure the perceived physical literacy of physical education teachers. It is argued that the instrument can be used for both research and applied purposes and potential uses for the instrument in physical education, medical and health settings are discussed.

    The triarchic model characterizes psychopathy in terms of three distinct dispositional constructs of boldness, meanness, and disinhibition. The model can be operationalized through scales designed specifically to index these domains or by using items from other inventories that provide coverage of related constructs. The present study sought to develop and validate scales for assessing the triarchic model domains using items from the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). A consensus rating approach was used to identify items relevant to each triarchic domain, and following psychometric refinement, the resulting MMPI-2-RF-based triarchic scales were evaluated for convergent and discriminant validity in relation to multiple psychopathy-relevant criterion variables in offender and nonoffender samples. Expected convergent and discriminant associations were evident very clearly for the Boldness and Disinhibition scales and somewhat less clearly for the Meanness scale. Moreover, hierarchical regression analyses indicated that all MMPI-2-RF triarchic scales incremented standard MMPI-2-RF scale scores in predicting extant triarchic model scale scores. The widespread use of MMPI-2-RF in clinical and forensic settings provides avenues for both clinical and research applications in contexts where traditional psychopathy measures are less likely to be administered.

    2011-08-01

    The contributions of genetic risk factors to susceptibility for brain disorders are often so closely intertwined with environmental factors that studying genes in isolation cannot provide the full picture of pathogenesis. With recent advances in our understanding of psychiatric genetics and environmental modifiers we are now in a position to develop more accurate animal models of psychiatric disorders which exemplify the complex interaction of genes and environment. Here, we consider some of the insights that have emerged from studying the relationship between defined genetic alterations and environmental factors in rodent models. A key issue in such animal models is the optimization of construct validity, at both genetic and environmental levels. Standard housing of laboratory mice and rats generally includes ad libitum food access and limited opportunity for physical exercise, leading to metabolic dysfunction under control conditions, and thus reducing validity of animal models with respect to clinical populations. A related issue, of specific relevance to neuroscientists, is that most standard-housed rodents have limited opportunity for sensory and cognitive stimulation, which in turn provides reduced incentive for complex motor activity. Decades of research using environmental enrichment has demonstrated beneficial effects on brain and behavior in both wild-type and genetically modified rodent models, relative to standard-housed littermate controls. One interpretation of such studies is that environmentally enriched animals more closely approximate average human levels of cognitive and sensorimotor stimulation, whereas the standard housing currently used in most laboratories models a more sedentary state of reduced mental and physical activity and abnormal stress levels. The use of such standard housing as a single environmental variable may limit the capacity for preclinical models to translate into successful clinical trials. Therefore, there is a need to

  16. Construct Validity of the Social Provisions Scale: A Bifactor Exploratory Structural Equation Modeling Approach.

    2016-12-01

    Extant theory posits well-differentiated dimensions of perceived social support as measured using the Social Provisions Scale (SPS). However, evidence is inconsistent with this multidimensionality perspective, with SPS factor correlations near unity and higher between-factor than within-factor item correlations. This article reports on research investigating the internal structure, gender invariance, and predictive validity of SPS scores. The analyses are conducted in a novel bifactor exploratory structural equation modeling (ESEM) framework, which is designed to account for presumed psychometric multidimensionality in SPS items due to (a) their fallibility as pure indicators of the constructs they are purported to measure and (b) the coexistence of general and specific factors. Based on 376 item responses, evidence was obtained for a bifactor-ESEM representation of the SPS data. In addition, support was found for the invariance of item thresholds and the latent mean invariance of six of the seven SPS factors in the retained solution. Only mean levels of Social Integration were found to differ by gender, with men scoring higher than women. Finally, evidence was obtained for the predictive validity of SPS scores with respect to loneliness and psychological well-being. Quite apart from yielding evidence validating the SPS, this research demonstrates the utility of bifactor ESEM for psychological assessment.

    Background The lack of tools to measure heart failure patients' knowledge about their syndrome when participating in rehabilitation programs demonstrates the need for specific recommendations regarding the amount or content of information required. Objectives To develop and validate a questionnaire to assess heart failure patients' knowledge about their syndrome when participating in cardiac rehabilitation programs. Methods The tool was developed based on the Coronary Artery Disease Education Questionnaire and applied to 96 patients with heart failure, with a mean age of 60.22 ± 11.6 years, 64% being men. Reproducibility was obtained via the intraclass correlation coefficient, using the test-retest method. Internal consistency was assessed by use of Cronbach's alpha, and construct validity, by use of exploratory factor analysis. Results The final version of the tool had 19 questions arranged in ten areas of importance for patient education. The proposed questionnaire had a clarity index of 8.94 ± 0.83. The intraclass correlation coefficient was 0.856, and Cronbach's alpha, 0.749. Factor analysis revealed five factors associated with the knowledge areas. Comparing the final scores with the characteristics of the population evidenced that low educational level and low income are significantly associated with low levels of knowledge. Conclusion The instrument has satisfactory clarity and validity indices, and can be used to assess the heart failure patients' knowledge about their syndrome when participating in cardiac rehabilitation programs.

    This study examined the validity of a state version of the Social Physique Anxiety Scale (Hart, Leary & Rejeski, 1989) by conducting tests of concurrent and discriminative validation. Participants were four separate samples of young women (N=221) who exercised ≤ 2 days/week and who participated in various experiments examining body image and self-presentation. Participants' scores on the state SPAS (S-SPAS) were significantly correlated, in expected directions, with scores on both trait and state measures of body image and self-presentation, and with body mass index (BMI). In addition, S-SPAS scores discriminated between women who exercised in a mixed-sex versus a same-sex environment, but trait SPAS scores did not. Together, these results provide evidence of construct validity of a state version of the SPAS and demonstrate that social physique anxiety can be conceptualized and measured as a situational variable. The S-SPAS, rather than the trait SPAS, should be employed in experiments designed to detect differences in state social physique anxiety.

  20. Measuring Constructs in Family Science: How Can Item Response Theory Improve Precision and Validity?

    2014-01-01

    This article provides family scientists with an understanding of contemporary measurement perspectives and the ways in which item response theory (IRT) can be used to develop measures with desired evidence of precision and validity for research uses. The article offers a nontechnical introduction to some key features of IRT, including its orientation toward locating items along an underlying dimension and toward estimating precision of measurement for persons with different levels of that same construct. It also offers a didactic example of how the approach can be used to refine conceptualization and operationalization of constructs in the family sciences, using data from the National Longitudinal Survey of Youth 1979 (n = 2,732). Three basic models are considered: (a) the Rasch and (b) two-parameter logistic models for dichotomous items and (c) the Rating Scale Model for multicategory items. Throughout, the author highlights the potential for researchers to elevate measurement to a level on par with theorizing and testing about relationships among constructs. PMID:25663714

  1. Construct validity of the WISC-IV with a referred sample: direct versus indirect hierarchical structures.

    The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) is one of the most frequently used intelligence tests in clinical assessments of children with learning difficulties. Construct validity studies of the WISC-IV have generally supported the higher order structure with four correlated first-order factors and one higher-order general intelligence factor, but recent studies have supported an alternate model in which general intelligence is conceptualized as a breadth factor rather than a superordinate factor (M. W. Watkins, 2010, Structure of the Wechsler Intelligence Scale for Children-Fourth Edition among a national sample of referred students, Psychological Assessment, Vol. 22, pp. 782-787; M. W. Watkins, G. L. Canivez, T. James, K. & R. Good, in press, Construct validity of the WISC-IVUK with a large referred Irish sample, International Journal of School and Educational Psychology). WISC-IV core subtest data obtained from evaluations to assess learning difficulties in 345 children (224 boys, 121 girls) were examined. One through four, first order factor models and indirect versus direct hierarchical models were compared using confirmatory factor analyses. The correlated four-factor Wechsler model provided good fit to these data, but the direct hierarchical model showed statistically significant improvement over the indirect hierarchical model and correlated four-factor model. The direct hierarchical model was judged the best explanation of the WISC-IV factor structure, with the general factor accounting for 71.6% of the common variance while the first order factors accounted for 2.4-10.3% of the common variance. Thus, the results with the present sample of referred children were similar to those from other investigations (G. E. Gignac, 2005, Revisiting the factor structure of the WAIS-R: Insights through nested factor modeling, Assessment, Vol. 12, pp. 320-329; G. E.

    The aims of this study were to test the face, content, and construct validities of a virtual-reality haptic arthroscopy simulator and to validate four assessment hypothesis. The participants in our study were 94 arthroscopists attending an international conference on arthroscopy. The interviewed surgeons had been performing arthroscopies for a mean of 8.71 years (σ = 6.94 years). We explained the operation, functionality, instructions for use, and the exercises provided by the simulator. They performed a trial exercise and then an exercise in which performance was recorded. After having using it, the arthroscopists answered a questionnaire. The simulator was classified as one of the best training methods (over phantoms), and obtained a mark of 7.10 out of 10 as an evaluation tool. The simulator was considered more useful for inexperienced surgeons than for surgeons with experience (mean difference 1.88 out of 10, P value < 0.001). The participants valued the simulator at 8.24 as a tool for learning skills, its fidelity at 7.41, the quality of the platform at 7.54, and the content of the exercises at 7.09. It obtained a global score of 7.82. Of the subjects, 30.8% said they would practise with the simulator more than 6 h per week. Of the surgeons, 89.4% affirmed that they would recommend the simulator to their colleagues. The data gathered support the first three hypotheses, as well as face and content validities. Results show statistically significant differences between experts and novices, thus supporting the construct validity, but studies with a larger sample must be carried out to verify this. We propose concrete solutions and an equation to calculate economy of movement. Analogously, we analyze competence measurements and propose an equation to provide a single measurement that contains them all and that, according to the surgeons' criteria, is as reliable as the judgment of experts observing the performance of an apprentice.

    Background: The goal of this study was to examine the construct validity of the diagnostic and statistical manual of mental disorder-5 (DSM-5) conceptual model of antisocial and borderline personality disorders (PDs). More specifically, the aim was to determine whether the DSM-5 five-factor structure of pathological personality trait domains replicated in an independently collected sample that differs culturally from the derivation sample. Methods: This study was on a sample of 346 individuals with antisocial (n = 122) and borderline PD (n = 130), and nonclinical subjects (n = 94). Participants randomly selected from prisoners, out-patient, and in-patient clients. Participants were recruited from Tehran prisoners, and clinical psychology and psychiatry clinics of Razi and Taleghani Hospital, Tehran, Iran. The SCID-II-PQ, SCID-II, DSM-5 Personality Trait Rating Form (Clinician's PTRF) were used to diagnosis of PD and to assessment of pathological traits. The data were analyzed by exploratory factor analysis. Results: Factor analysis revealed a 5-factor solution for DSM-5 personality traits. Results showed that DSM-5 has adequate construct validity in Iranian sample with antisocial and borderline PDs. Factors similar in number with the other studies, but different in the content. Conclusions: Exploratory factor analysis revealed five homogeneous components of antisocial and borderline PDs. That may represent personality, behavioral, and affective features central to the disorder. Furthermore, the present study helps understand the adequacy of DSM-5 dimensional approach to evaluation of personality pathology, specifically on Iranian sample. PMID:25709797

    We analyzed WAIS-III/WMS-III standardization data for evidence of the construct validity and clinical utility of the Digit Symbol-Incidental Learning procedures (Pairing and Free Recall). Scores on both tests correlated moderately with WMS-III memory index scores (mean r=.38 for Pairing and .36 for Free Recall). Cutoff scores can be used to identify younger and older adults likely to suffer from memory impairment. In the standardization sample (which excludes neurological patients), these have moderate positive predictive power (averaging .56 if either test yields a positive finding), moderate negative predictive power (.76), and high specificity (.88), but low sensitivity (.35). In a clinical sample, the same cutoff scores were much more sensitive, correctly identifying 88% of a group of patients with Alzheimer's Disease. Examinees who obtain these low scores should receive follow-up memory testing. Very high scores are associated with a reduced risk of memory impairment.

    Based on the World Health Organization's standardized survey inventories assessing AIDS-related knowledge, attitudes, beliefs, and practices (KABP) for adolescents, a written questionnaire was developed and pilot tested among primary school children in Northern Tanzania. Subjects included 472 fifth and sixth graders at four schools in Arusha and Kilimanjaro regions. Results indicated that the large majority of the students understood the questions and were able and willing to complete the survey. Non-response patterns did not seem to be related to the sensitivity of included questions. AIDS-related knowledge and attitudes toward engaging in sexual behavior had acceptable reliability and construct validity when compared with similar surveys in Western countries, while perceived social norms and self-efficacy need further development. KABP questionnaires may serve as a useful method in AIDS-related surveys and evaluation studies among school children in Tanzania if survey instruments are adapted to reflect the local social and cultural context.

    Concerns over the increasing popularity of wilderness recreation have resulted in attempts to determine the amount of use that different areas can tolerate without adverse affects to the resource. Early attempts to establish recreational carrying capacities focused on managers’ assessments of biophysical impacts. The perceptions of wilderness visitors, however, are now considered integral to capacity decisions. This study used a stress appraisal framework to understand wilderness visitors’ perceptions of on-site conditions. It was based on the premise that negative appraisals of wilderness conditions produce stress and that individual perceptions vary based on personal and situational characteristics. The purpose of the study was to assess the validity of a wilderness-hassles appraisal scale by testing hypothesized relationships between experience-use history (EUH), place attachment, and stress appraisal. Data collection occurred through a postal survey of hikers ( n = 385) contacted in the High Peaks and Pemigewasset Wilderness Areas during the summer of 2004. An exploratory factor analysis indicated that stress appraisal is a multi-dimensional construct. Validity testing procedures were restricted to those dimensions that were consistent between study areas and provided partial support for the hassles scale. As hypothesized, EUH did not influence perceptions of wilderness conditions. Place attachment, on the other hand, was positively correlated with stressful appraisals of social and managerial conditions. Although Kruskall Wallis tests revealed significant differences in visitors’ perceptions of managerial conditions between study sites, perceptions of social conditions did not vary significantly. Implications for management and recommendations for further refinement of the wilderness hassles construct are discussed.

    Context The Brief Pain Inventory (BPI) is a frequently used instrument designed to assess the patient-reported outcome of pain. The majority of factor analytic studies have found a two-factor (i.e., pain intensity and pain interference) structure for this instrument; however, since the BPI was developed with an a priori hypothesis of the relationship among its items, it follows that construct validity investigations should utilize confirmatory factor analysis (CFA). Objectives The purpose of this work is to establish the construct validity of the BPI using a CFA framework and demonstrate factorial invariance using a range of demographic variables. Methods A retrospective CFA was completed in a sample of individuals diagnosed with HIV/AIDS and cancer (n = 364; 63% male; age 21-92 years, M = 51.80). A baseline one-factor model was compared against two-factor and three-factor models (i.e., pain intensity, activity interference, and affective interference) that were developed based on the hypothetical design of the instrument. Results Fit indices for the three-factor model were statistically superior when compared to the one-factor model and marginally better in comparison to the two-factor model. This three-factor structure was found to be invariant across disease, age, and ethnicity groups. Conclusion The results of this study provide evidence to support a three-factor representation of the BPI, as well as the originally hypothesized two-factor structure. Such findings will begin to provide clinical trialists, pharmaceutical sponsors, and regulators with confidence in the psychometric properties of this instrument when considering its inclusion in clinical research.

    The occurrence of extreme heat and its adverse effects will be exacerbated with the trend of global warming. An increasing number of researchers have been working on aggregating multiple heat-related indicators to create composite indices for heat vulnerability assessments and have visualized the vulnerability through geographic information systems to provide references for reducing the adverse effects of extreme heat more effectively. This review includes 15 studies concerning heat vulnerability assessment. We have studied the indicators utilized and the methods adopted in these studies for the construction of the heat vulnerability index (HVI) and then further reviewed some of the studies that validated the HVI. We concluded that the HVI is useful for targeting the intervention of heat risk, and that heat-related health outcomes could be used to validate and optimize the HVI. In the future, more studies should be conducted to provide references for the selection of heat-related indicators and the determination of weight values of these indicators in the development of the HVI. Studies concerning the application of the HVI are also needed. PMID:26132476

    There is an enormous demand for new therapeutic interventions for a range of major disorders. The majority of clinical trials in recent years have been unsuccessful despite highly promising preclinical data. Therefore, an urgent issue confronting both the academic and commercial medical research sectors is how to optimize translation of preclinical studies. The vast majority of preclinical studies are currently performed using laboratory mice and rats. We will discuss the various opportunities for optimization of animal models of CNS disorders. One limitation of current approaches is that most studies are conducted on sedentary, unstimulated animals with unlimited access to food in the home cage, thus leading to metabolic and physiological compromise. Environmental enrichment, which enhances sensory stimulation, cognitive activity and physical exercise, has been demonstrated to induce dramatic effects on brain and behavior in both wild-type and genetically modified rodent models, relative to standard-housed littermate controls. Environmental enrichment also exerts beneficial effects outside the CNS, such as a reduction in excess body fat. We propose that therapeutic interventions which are found to show promise in standard-housed preclinical models should be subsequently tested under conditions of greater environmental enrichment to identify therapeutics which continue to show efficacy in housing contexts of superior 'environmental construct validity'. Other possible approaches to optimize the quality, validity and reporting of preclinical studies in animal models are also discussed.

    The present study deals with the problem of speeding behavior on rural roads. The purpose of the paper is to examine the construct validity and the internal consistency and reliability of a questionnaire that measures the determinants of speeding behavior. In addition, it aimed to test the predictive validity of a modified theoretical framework of a theory of planned behavior (TPB) in relation to speeding behavior. A total of 546 car drivers from five local communities in the Republic of Srpska successfully completed the questionnaire after reading the scenario. The principal component analysis revealed seven components interpreted as: personal norm, perceived behavioral control, affective attitude toward speeding, subjective norm, habit, descriptive norm, and cognitive attitude toward speeding. A speeding behavior model was developed by structural equation modeling. Personal norm, subjective norm, and affective attitudes were shown to be important variables within the modified TPB in understanding speeding behavior. Overall, the present findings provide significant support for the concept of the modified theoretical framework of TPB in relation to speeding behavior on rural roads. Implications for a speeding behavior model and interventions are discussed.

    The authors report final-year ward simulation data from the University of Dundee Medical School. Faculty who designed this assessment intend for the final score to represent an individual senior medical student's level of clinical performance. The results are included in each student's portfolio as one source of evidence of the student's capability as a practitioner, professional, and scholar. Our purpose in conducting this study was to illustrate how assessment designers who are creating assessments to evaluate clinical performance might develop propositions and then collect and examine various sources of evidence to construct and evaluate a validity argument. The data were from all 154 medical students who were in their final year of study at the University of Dundee Medical School in the 2010-2011 academic year. To the best of our knowledge, this is the first report on an analysis of senior medical students' clinical performance while they were taking responsibility for the management of a simulated ward. Using multi-facet Rasch measurement and a generalizability theory approach, we examined various sources of validity evidence that the medical school faculty have gathered for a set of six propositions needed to support their use of scores as measures of students' clinical ability. Based on our analysis of the evidence, we would conclude that, by and large, the propositions appear to be sound, and the evidence seems to support their proposed score interpretation. Given the body of evidence collected thus far, their intended interpretation seems defensible.

    Background: Training models in laparoscopic surgery allow the surgical team to practice procedures in a safe environment. We have proposed the use of a 4-task, low-cost inert model to practice critical steps of laparoscopic common bile duct exploration. Methods: The performance of 3 groups with different levels of expertise in laparoscopic surgery, novices (A), intermediates (B), and experts (C), was evaluated using a low-cost inert model in the following tasks: (1) intraoperative cholangiography catheter insertion, (2) transcystic exploration, (3) T-tube placement, and (4) choledochoscope management. Kruskal-Wallis and Mann-Whitney tests were used to identify differences among the groups. Results: A total of 14 individuals were evaluated: 5 novices (A), 5 intermediates (B), and 4 experts (C). The results involving intraoperative cholangiography catheter insertion were similar among the 3 groups. As for the other tasks, the expert had better results than the other 2, in which no significant differences occurred. The proposed model is able to discriminate among individuals with different levels of expertise, indicating that the abilities that the model evaluates are relevant in the surgeon's performance in CBD exploration. Conclusions: Construct validity for tasks 2 and 3 was demonstrated. However, task 1 was no capable of distinguishing between groups, and task 4 was not statistically validated. PMID:22906323

    As an instrument to assess specific psychodynamic dimensions, the Operationalized Psychodynamic Diagnostics in Childhood and Adolescence (OPD-CA) is widely used in clinical care and psychotherapeutic training. However, the psychometric validation of its axes is partly still missing. The aim of this study was to test the reliability and construct validity of the axes structure and prerequisites of treatment. 171 children and adolescents (aged 4 to 21 years) with a diagnosed psychiatric disorder who began an analytic psychotherapy were additionally assessed with the OPD-CA by their therapists (n = 25) in the context of naturalistic care in private practice. Therapists were all qualified as analytic child and adolescent psychotherapists and underwent a standardized OPD-CA training. Results indicated conceptually meaningful factor structures for both axes tested. These factor structures predominantly followed the conceptually defined dimensions. Internal consistency was high for the axis structure, modest to low fort he axis prerequisites of treatment. Implications and recommendations for a future revision of the OPD-CA with particular respect of single items and their operationalization are discussed.

    Surprisingly few ecologically-valid assessments of executive function exist, but the Baycrest Multiple Errands Test (BMET) shows promise in identifying executive impairment. The goal of the present study was to develop both a revised version of the assessment (BMET-R), to improve the test's ability to discriminate between patients and healthy participants, and an alternate form of the BMET-R to permit repeat testing. Sixteen individuals with acquired brain injury (ABI) due to stroke or trauma and 16 healthy participants completed a series of neuropsychological assessments, questionnaires, the BMET-R and its alternate form (in counterbalanced order). The results of the study indicated that participants with ABI omitted more tasks, broke more rules, and were less efficient than healthy participants on both the revised BMET-R and its alternate form. Moreover, significant correlations were found between the two versions of the BMET-R for task completions, omissions, errors, rule breaks and inefficiencies but few significant correlations were observed between the BMET-R versions and measures of executive dysfunction in everyday life. These results indicate that the two versions of the BMET-R are able to dissociate the performance of participants with ABI from that of healthy participants. However, despite overlaps in performance and correlations between the two versions of the BMET-R, they did not identically assess executive deficits. This suggests that caution should be used when constructing and validating alternate versions of performance-based assessments.

    Multilevel linguistic features have been proposed for discourse analysis, but there have been few applications of multilevel linguistic features to readability models and also few validations of such models. Most traditional readability formulae are based on generalized linear models (GLMs; e.g., discriminant analysis and multiple regression), but these models have to comply with certain statistical assumptions about data properties and include all of the data in formulae construction without pruning the outliers in advance. The use of such readability formulae tends to produce a low text classification accuracy, while using a support vector machine (SVM) in machine learning can enhance the classification outcome. The present study constructed readability models by integrating multilevel linguistic features with SVM, which is more appropriate for text classification. Taking the Chinese language as an example, this study developed 31 linguistic features as the predicting variables at the word, semantic, syntax, and cohesion levels, with grade levels of texts as the criterion variable. The study compared four types of readability models by integrating unilevel and multilevel linguistic features with GLMs and an SVM. The results indicate that adopting a multilevel approach in readability analysis provides a better representation of the complexities of both texts and the reading comprehension process.

    The Wnt/β-catenin signaling pathway is important for multiple developmental processes and tissue maintenance in adults. Consequently, deregulated signaling is involved in a range of human diseases including cancer and developmental defects. A better understanding of the intricate regulatory mechanism and effect of physiological (active) and pathophysiological (hyperactive) WNT signaling is important for predicting treatment response and developing novel therapies. The constitutively expressed CTNNB1 (commonly and hereafter referred to as β-catenin) is degraded by a destruction complex, composed of amongst others AXIN1 and GSK3. The destruction complex is inhibited during active WNT signaling, leading to β-catenin stabilization and induction of β-catenin/TCF target genes. In this study we investigated the mechanism and effect of β-catenin stabilization during active and hyperactive WNT signaling in a combined in silico and in vitro approach. We constructed a Petri net model of Wnt/β-catenin signaling including main players from the plasma membrane (WNT ligands and receptors), cytoplasmic effectors and the downstream negative feedback target gene AXIN2. We validated that our model can be used to simulate both active (WNT stimulation) and hyperactive (GSK3 inhibition) signaling by comparing our simulation and experimental data. We used this experimentally validated model to get further insights into the effect of the negative feedback regulator AXIN2 upon WNT stimulation and observed an attenuated β-catenin stabilization. We furthermore simulated the effect of APC inactivating mutations, yielding a stabilization of β-catenin levels comparable to the Wnt-pathway activities observed in colorectal and breast cancer. Our model can be used for further investigation and viable predictions of the role of Wnt/β-catenin signaling in oncogenesis and development. PMID:27218469

    In this study, we examined the reliability and construct validity of new soccer skills tests. Twenty soccer players (10 professional and 10 recreational) repeated trials of passing, shooting, and dribbling skills on different days. Passing and shooting skills required players to kick a moving ball, delivered at constant speed, towards one of four randomly determined targets. Dribbling required players to negotiate seven cones over 20 m. Each trial consisted of 28 passes, 8 shots, and 10 dribbles. Ball speed, precision, and success were determined for all tests using video analysis. Systematic bias was small (<9% in all measures) and all outcome measures were similar between trials. Test-retest reliability statistics were as follows: ball speed (passing, shooting, dribbling; coefficient of variation [CV]: 6.5%, 6.9%, 2.4%; ratio limits of agreement [RLOA]: 0.958 ×/÷ 1.091, 0.990 ×/÷ 1.107, 0.993 ×/÷ 1.039), precision (passing, shooting, dribbling; CV: 10.0%, 23.5%, 4.6%; RLOA: 0.956 ×/÷ 1.147, 1.030 ×/÷ 1.356, 1.000 ×/÷ 1.068), and success (passing, shooting, dribbling; CV: 11.7%, 14.4%, 2.2%; RLOA: 1.017 ×/÷ 1.191, 0.913 ×/÷ 1.265, 0.996 ×/÷ 1.035). Professional players performed better than recreational players in at least one outcome measure for all skills. These findings demonstrate the reliability and validity of new soccer skill protocols.

    Limited studies have evaluated the psychometric properties of the Muscle Appearance Satisfaction Scale (MASS), a measure of muscle dysmorphia, in different cultures and languages. The aims were to examine the psychometric properties of the Hungarian version of the MASS (MASS-HU), and to investigate its relationship with self-esteem and exercise-related variables. Two independent samples of male weight lifters (ns=289 and 43), and a sample of undergraduates (n=240) completed the MASS, Eating Disorder Inventory, and Rosenberg Self-esteem Scale. Exploratory factor analysis supported the original five-factor structure of the MASS only in the weight lifter sample. The MASS-HU had excellent scale score reliability and good test-retest reliability. The construct validity of the MASS-HU was tested with multivariate regression analyses which indicated an inverse relationship between self-esteem and muscle dysmorphia. The 18-item MASS-HU was found to be a useful measure for the assessment of muscle dysmorphia among male weight lifters.

    Objective Many bench-top surgical simulators assess laparoscopic proficiency, yet few address core open surgical skills. The purpose of this study is to describe a cost-effective bench-top vessel-ligation simulator and provide construct validation. Design Prospective comparison of blinded proficiency assessments among participants performing a bench-top vessel-ligation simulation task. Evaluations were performed using Objective Structured Assessments of Technical Skills. Setting This study took place at the University of Virginia School of Medicine, a large academic medical institution. Participants Participants included fourth-year medical students participating in a focused surgical elective course (N = 16), post-graduate year (PGY) 2–3 surgery residents (N = 6), and surgical faculty (N = 5). Results Fixed costs of the vessel-ligation simulator totaled $30. Flexible costs of operation were less than $0.20 per attempt. Median task-specific checklist scores among medical students, residents, and faculty were 4.83, 7.33, and 7.67, respectively. Median global rating scores across the three groups were 2.29, 4.43, and 4.76, respectively. Significant proficiency differences were noted between students and residents/faculty for both metrics (p < 0.001). Conclusions A cost-effective bench-top simulator can effectively measure proficiency with basic open surgical techniques such as vessel-ligation. Among junior surgical trainees, this tool can identify learning gaps and improve operative skills in a pre-clinical setting. PMID:25678049

    In this study, we constructed dual-transgene vectors (pDT1, pDT7, and pDT7G) that simultaneously co-expressed two genes in plants. ACTIN2 and UBQ10 promoters were used to control the expression of these two genes. The 4×Myc, 3×HA, and 3×Flag reporter genes allowed for the convenient identification of a tunable co-expression system in plants, whereas the dexamethasone (Dex) inducible reporter gene C-terminus of the glucocorticoid receptor (cGR) provided Dex-dependent translocation of the fusion gene between the nucleus and cytoplasm. The function of pDT vectors was validated using four pairwise genes in Nicotiana benthamiana or Arabidopsis thaliana. The co-expression efficiency of two genes from the pDT1 and pDT7G vectors was 35% and 42%, respectively, which ensured the generation of sufficient transgenic materials. These pDT vectors are simple, reliable, efficient, and time-saving tools for the co-expression of two genes through a single transformation event and can be used in the study of protein-protein interactions or multi-component complexes.

  4. Construction and initial validation of the Gendered Racial Microaggressions Scale for Black women.

    The purpose of this study was to develop a measure of gendered racial microaggressions (i.e., subtle and everyday verbal, behavioral, and environmental expressions of oppression based on the intersection of one's race and gender) experienced by Black women by applying an intersectionality framework to Essed's (1991) theory of gendered racism and Sue, Capodilupo, et al.'s (2007) model of racial microaggressions. The Gendered Racial Microaggressions Scale (GRMS), was developed to assess both frequency and stress appraisal of microaggressions, in 2 separate studies. After the initial pool of GRMS items was developed, we received input from a community-based focus group of Black women and an expert panel. In Study 1, an exploratory factor analysis using a sample of 259 Black women resulted in a multidimensional scale with 4 factors as follows: (a) Assumptions of Beauty and Sexual Objectification, (b) Silenced and Marginalized, (c) Strong Black Woman Stereotype, and (d) Angry Black Woman Stereotype. In Study 2, results of confirmatory factor analyses using an independent sample of 210 Black women suggested that the 4-factor model was a good fit of the data for both the frequency and stress appraisal scales. Supporting construct validity, the GRMS was positively related to the Racial and Ethnic Microaggressions Scale (Nadal, 2011) and the Schedule of Sexist Events (Klonoff & Landrine, 1995). In addition, the GRMS was significantly related to psychological distress, such that greater perceived gendered racial microaggressions were related to greater levels of reported psychological distress. Implications for future research and practice are discussed.

    The DSM-5 Section III model of personality disorders remains largely unexplored in older adults. More specifically, there is a need for further research on the generalizability of the five trait domains in old age. The development of a short operationalization to screen for maladaptive trait domains, the Personality Inventory for DSM-5 Brief Form (PID-5-BF), can stimulate the use of the alternative DSM-5 model in older adults by addressing the need for short instruments. The primary goal of this study was to examine the construct validity of the PID-5-BF by comparing its structural model and nomological network with the original PID-5 in terms of relations with domains of personality functioning and a gero-specific personality disorder indicator. A five-factor model was supported, but the domain Disinhibition was not replicated in the original PID-5, and some PID-5-BF items showed weak loadings. Nevertheless, the nomological network was similar and showed meaningful relations, supporting the use of the Brief PID-5 in older clinical samples.

  6. Bilingual advantages in executive functioning: problems in convergent validity, discriminant validity, and the identification of the theoretical constructs

    2014-01-01

    A sample of 58 bilingual and 62 monolingual university students completed four tasks commonly used to test for bilingual advantages in executive functioning (EF): antisaccade, attentional network test, Simon, and color-shape switching. Across the four tasks, 13 different indices were derived that are assumed to reflect individual differences in inhibitory control, monitoring, or switching. The effects of bilingualism on the 13 measures were explored by directly comparing the means of the two language groups and through regression analyses using a continuous measure of bilingualism and multiple demographic characteristics as predictors. Across the 13 different measures and two types of data analysis there were very few significant results and those that did occur supported a monolingual advantage. An equally important goal was to assess the convergent validity through cross-task correlations of indices assume to measure the same component of executive functioning. Most of the correlations using difference-score measures were non-significant and many near zero. Although modestly higher levels of convergent validity are sometimes reported, a review of the existing literature suggests that bilingual advantages (or disadvantages) may reflect task-specific differences that are unlikely to generalize to important general differences in EF. Finally, as cautioned by Salthouse, assumed measures of executive functioning may also be threatened by a lack of discriminant validity that separates individual or group differences in EF from those in general fluid intelligence or simple processing speed.

    1998-01-01

    STUDY OBJECTIVE: The purpose of this study was to construct and validate a behavioral risk index scale to determine if the scaled variable could be used to study possible latent dimensions of risk behaviour. DESIGN: Data from the Minnesota Behavioral Risk Factor Surveillance System (BRFSS) were used to construct and validate a behavioral risk index using item response theory methods. PARTICIPANTS: A representative sample of 3303 Minnesota adults 18 years of age and older. RESULTS: Massive evidence was found against the construct validity of the index scale as a measure of risk behaviour. Seven commonly studied risk behaviours could not be scaled into a valid construct of health behaviour for either men or women. Tests of scalability, homogeneity, and item independence were rejected. In addition, item bias was found for all of the items in relation to important exogenous variables, especially age and education. CONCLUSIONS: The risk behaviours do not represent sufficiently similar types of phenomena to form an additive scale of health related risk taking. Not only do the practices fall on different, undefined dimensions of behavior, subgroup differences in risk taking would be hidden by data reductions summing the behavioral practices into additive scales. The findings indicate that the behaviors have quite distinct meanings that should be studied separately.   PMID:9616426

    Movakic is a newly developed instrument for measurement of motor abilities in children with severe multiple disabilities, with a satisfactory feasibility and content validity and good inter-observer and test-retest reliability. The objective of this study was to investigate its construct validity and responsiveness to change. Sixty children with severe multiple disabilities (mean age 7.7 years, range 2-16) were measured using Movakic six times during 18 months. Construct validity was assessed by correlating Movakic scores with expert judgment. In order to assess responsiveness, scores during 3-months intervals were compared (mean score-changes and intraclass correlations) during which some children experienced meaningful events influencing motor abilities and during which others experienced no such event. Forty-five percent of children had a lower cognitive development level than 6-month, 52% had Gross Motor Function Classification System level V and 37% had level IV. For 27 children all measurements were completed, six children dropped out. Construct validity was good (r=0.50-0.71). Responsiveness was demonstrated by significantly larger score changes after events than when such events did not occur. Movakic is a valid instrument for measuring motor abilities in children with severe multiple disabilities. Results suggest responsiveness to change in motor abilities after meaningful events.

    Tibbles, Anthony C; Waalen, Judith K; Hains, François C

    1998-01-01

    Background: The Oswestry Low Back Pain Disability Questionnaire (ODQ) is a widely used 10-item paper and pencil measure of disability resulting from low back pain. However, few studies have assessed the psychometric properties of the instrument. This study evaluated the response set bias, the internal consistency, and the construct validity of the ODQ. Objectives: The original ODQ was compared to seven modified versions to examine whether a response set bias existed. The internal consistency of the ODQ was assessed using the Cronbach alpha. Finally, the relationship between scores on the ODQ and the Roland Morris Functional Disability Scal (RM) was examined. Methods: Seven modified versions of the ODQ were developed from the original. One of the eight versions was randomly allocated to 102 adult patients presenting with low lack pain. There was no attempt to select patients on the basis of pain intensity or prior treatment so as to maximize the range and diversity of low back pain sufferers. Results: Results suggest that the responses given on the eight versions of the ODQ are a function of content and not of the format in which the items are presented. The ODQ also has strong internal consisstency (alpha = 0.85) and is strongly correlated to the RM (r = .70, p = .0005). The ODQ is a significant predictor of the RM scores (T-9.45, p = .0005) and duration of symptoms (T = -2.17, p = .0325). Conclusion: The ODQ appears to possess stable psychometric properties. The use of more than one version provides practitioners with a means of repeatedly assessing the disability levels of patients suffering from low back pain over the course of treatment.

  14. The value of suppressor effects in explicating the construct validity of symptom measures.

    PubMed

    Watson, David; Clark, Lee Anna; Chmielewski, Michael; Kotov, Roman

    2013-09-01

    Suppressor effects are operating when the addition of a predictor increases the predictive power of another variable. We argue that suppressor effects can play a valuable role in explicating the construct validity of symptom measures by bringing into clearer focus opposing elements that are inherent--but largely hidden--in the measure's overall score. We illustrate this point using theoretically grounded, replicated suppressor effects that have emerged in analyses of the original Inventory of Depression and Anxiety Symptoms (IDAS; Watson et al., 2007) and its expanded 2nd version (IDAS-II; Watson et al., 2012). In Study 1, we demonstrate that the IDAS-II Appetite Gain and Appetite Loss scales contain both (a) a shared distress component that creates a positive correlation between them and (b) a specific symptom component that produces a natural negative association between them (i.e., people who recently have experienced decreased interest in food/loss of appetite are less likely to report a concomitant increase in appetite/weight). In Study 2, we establish that mania scales also contain 2 distinct elements-namely, high energy/positive emotionality and general distress/dysfunction-that oppose each another in many instances. In both studies, we obtained evidence of suppression effects that were highly robust across different types of respondents (e.g., clinical outpatients, community adults, college students) and using both self-report and interview-based measures. These replicable suppressor effects establish that many homogeneous, unidimensional symptom scales actually contain distinguishable components with distinct--at times, even antagonistic--properties.

  15. Validation of Bim Components by Photogrammetric Point Clouds for Construction Site Monitoring

    NASA Astrophysics Data System (ADS)

    2015-03-01

    Construction progress monitoring is a primarily manual and time consuming process which is usually based on 2D plans and therefore has a need for an increased automation. In this paper an approach is introduced for comparing a planned state of a building (as-planned) derived from a Building Information Model (BIM) to a photogrammetric point cloud (as-built). In order to accomplish the comparison a triangle-based representation of the building model is used. The approach has two main processing steps. First, visibility checks are performed to determine whether or not elements of the building are potentially built. The remaining parts can be either categorized as free areas, which are definitely not built, or as unknown areas, which are not visible. In the second step it is determined if the potentially built parts can be confirmed by the surrounding points. This process begins by splitting each triangle into small raster cells. For each raster cell a measure is calculated using three criteria: the mean distance of the points, their standard deviation and the deviation from a local plane fit. A triangle is confirmed if a sufficient number of raster cells yield a high rating by the measure. The approach is tested based on a real case inner city scenario. Only triangles showing unambiguous results are labeled with their statuses, because it is intended to use these results to infer additional statements based on dependencies modeled in the BIM. It is shown that the label built is reliable and can be used for further analysis. As a drawback this comes with a high percentage of ambiguously classified elements, for which the acquired data is not sufficient (in terms of coverage and/or accuracy) for validation.

    This study presents the psychometric properties of the Brazilian version of the Appraisal of Self-Care Agency Scale - Revised (ASAS-R). The sample was made up of 627 subjects (69.8% women) aged between 18 and 88 years (mean = 38.3; SD = 13.26) from 17 Brazilian states. Exploratory factor analysis of part of the sample (n1 = 200) yielded a three-factor solution which showed adequate levels of reliability. Two confirmatory factor analyses of the other part of the sample (n2 = 427) tested both the exploratory and the original model. The analysis of convergent validity using the Subjective Happiness Scale, the Satisfaction with Life Scale, and the 36-item Short Form Health Survey Version 2 (SF-36v2) demonstrated adequate levels of validity. A significant correlation was found between levels of self-care agency and age, level of education and income. The analysis of sample members with chronic disease (n = 134) showed that higher levels of self-care agency indicated lower levels of negative impact of the chronic illness in the individual's everyday life.

    Electroconvulsive therapy is the most effective therapy for major depressive disorder (MDD). The remission rate is above 50% in previously pharmacoresistant patients but the mechanisms of action are not fully understood. Electroconvulsive stimulation (ECS) in rodents mimics antidepressant electroconvulsive therapy (ECT) in humans and is widely used to investigate the underlying mechanisms of ECT. For the translational value of findings in animal models it is essential to establish models with the highest construct, face and predictive validity possible. The commonly used model for ECT in rodents does not meet the demand for high construct validity. For ECT, cortical surface electrodes are used to induce therapeutic seizures whereas ECS in rodents is exclusively performed by auricular or corneal electrodes. However, the stimulation site has a major impact on the type and spread of the induced seizure activity and its antidepressant effect. We propose a method in which ECS is performed by screw electrodes placed above the motor cortex of rats to closely simulate the clinical situation and thereby increase the construct validity of the model. Cortical ECS in rats induced reliably seizures comparable to human ECT. Cortical ECS was more effective than auricular ECS to reduce immobility in the forced swim test. Importantly, auricular stimulation had a negative influence on the general health condition of the rats with signs of fear during the stimulation sessions. These results suggest that auricular ECS in rats is not a suitable ECT model. Cortical ECS in rats promises to be a valid method to mimic ECT.

    Purpose/Background: Posterior shoulder tightness (PST) has been implicated in the etiology of numerous shoulder disorders. Therefore, clinicians and researchers must have a reliable and valid method for quantifying PST. The purpose of this study was to investigate the interrater reliability, minimal detectable change at the 90% confidence interval (MDC90) and construct validity of an inclinometric measurement designed to quantify PST. Methods: Two investigators each performed sidelying PST measurements on the non-dominant shoulder of 45 asymptomatic participants in a blinded repeated measures design. Upon completion of the PST measurements, one rater assessed active internal and external rotation for the validity component of the investigation. Results: Interrater reliability using an intraclass correlation coefficient (ICC) model 2,k was good (ICC 5 0.90). The MDC90 indicated that a change of greater than or equal to 9 degrees would be required to be 90% certain that a change in the measurement would not be the result of inter-trial variability or measurement error. Construct validity was evaluated using active internal rotation for convergence and external rotation for discrimination. Construct validity was supported by a good to excellent relationship between PST and internal rotation (r 5 0.88) and by an inverse relationship between PST and external rotation (r 5 20.07). Conclusion: The sidelying procedure described in this investigation appears to be a reliable and valid means for quantifying PST when strict measurement protocols are adhered to. An advantage of this procedure lies in the ability to control scapular position to ensure motion is limited to the glenohumeral joint. Moreover, the use of inclinometry provides an absolute angle of tightness that may be used for intersubject comparison, documenting change, and to determine reference values. Clinicians and researchers should consider the MDC values presented when interpreting change values during

    We conducted a series of studies to investigate the psychometric properties of the Social Physique Anxiety Scale (SPAS; Hart, Leary, & Rejeski, 1989) among a total sample of 1,563 nonclinical French adolescents. The, first study provided support for the item content of the preliminary version of the French SPAS for adolescents. Then, the second study supported the convergent validity of the English and French version of the SPAS. Finally, Studies 3 to 6 provided support for the factor validity, measurement invariance (across genders, age groups and samples), latent mean structure invariance (across age category and samples), reliability, convergent validity, and criterion-related validity of a 7-item version of the SPAS.

    Our study tested the discriminant validity of burnout in contrast to depression using the Maslach Burnout Inventory (MBI, Maslach u. Jackson 1986) and the Allgemeine Depressionsskala (ADS, Hautzinger u. Bailer 1993). Furthermore the relationships between burnout and depression to social support, occupational and health variables were examined. Pre-school teachers (n = 101), physician-assistants (n = 81) and their intimates were asked to complete a self-administered questionnaire. Spearman-correlations and factor analysis were conducted with SPSS. The results indicate validity for the burnout construct.

  2. Development and preliminary validation of the Constructive and Unconstructive Worry Questionnaire: A measure of individual differences in constructive versus unconstructive worry.

    2016-11-01

    This article presents a measure of individual differences in the tendencies to worry constructively and unconstructively, called the Constructive and Unconstructive Worry Questionnaire (CUWQ). The measure is based on a control theory perspective of worry and separates the tendency to worry in a way that facilitates goal-pursuit and threat reduction (constructive worry) from the tendency to worry in a way that hinders goal-pursuit while sustaining threat awareness (unconstructive worry). CUWQ scores were validated in 2 independent nonclinical samples, including North American (Sample 1, N = 295) and Australian (Sample 2, N = 998) residents. Final factor items were selected based on Sample 1, and the measure showed good model fit through a confirmatory factor analysis in Sample 2. In addition, scores on the 2 worry factors showed criterion-related validity by statistically predicting a variety of outcomes in both samples: Constructive worry was positively associated with punctuality and wildfire preparedness and negatively associated with trait-anxiety and amount of worry. Unconstructive worry, on the other hand, was positively associated with trait-anxiety and amount of worry, and negatively associated with punctuality and wildfire preparedness. The 2 factor scores were uncorrelated in Sample 1 and positively correlated in Sample 2, thereby showing that having a tendency to worry in an unconstructive manner does not prohibit 1 from worrying in a constructive manner as well. Understanding how the 2 tendencies to worry differ from each other and separating their measurement enables a better understanding of the role of worry in both normal behavior and psychopathology.

    2016-01-15

    The primary goal of this study was to explicate the construct validity of the Narcissistic Personality Inventory (NPI) and the Hypomanic Personality Scale (HPS) by examining their relations both to each other and to measures of personality and psychopathology in a community sample (N = 255). Structural evidence indicates that the NPI is defined by Leadership/Authority, Grandiose Exhibitionism, and Entitlement/Exploitativeness factors, whereas the HPS is characterized by specific dimensions reflecting Social Vitality, Mood Volatility, and Excitement. Our results establish that (a) factor-based subscales from these instruments display divergent patterns of relations that are obscured when relying exclusively on total scores and (b) some NPI and HPS subscales more clearly tap content specifically relevant to narcissism and mania, respectively, than others. In particular, our findings challenge the construct validity of the NPI Leadership/Authority and HPS Social Vitality subscales, which appear to assess overlapping assertiveness content that is largely adaptive in nature.

    2015-01-21

    This study aimed at testing the reliability and construct validity of a trunk perturbation protocol (TPP) that estimates the intrinsic and reflexive contributions to low-back stiffness. The TPP consists of a series of pseudorandom position-controlled trunk perturbations in an apparatus measuring forces and displacements at the harness surrounding the thorax. Intrinsic and reflexive contributions to low-back stiffness were estimated using a system identification procedure, leading to 12 parameters. Study 1 methods (reliability): 30 subjects performed five 75-s trials, on each of two separate days (eight weeks apart). Reliability was assessed using the generalizability theory, which allowed computing indexes of dependability (ϕ, analogous to intraclass correlation coefficient) and standard errors of measurement (SEM). Study 2 methods (validity): 20 healthy subjects performed three 75-s trials for each of five experimental conditions assumed to provide different lumbar stiffness; testing the construct validity of the TPP using four conditions with different lumbar belt designs and one control condition without. Study 1 results (reliability): Learning was seen between the first and following trials. Consequently, reliability analyses were performed without the first trial. Simulations showed that averaging the scores of three trials can lead to acceptable reliability results for some TPP parameters. Study 2 results (validity): All lumbar belt designs increased low-back intrinsic stiffness, while only some of them decreased reflex stiffness, which support the construct validity of the TPP. Overall, these findings support the use of the TPP to test the effect of rehabilitation or between-groups differences with regards to trunk stiffness.

    The factor structure and the convergent validity of the Personality Inventory for DSM-5 (PID-5), a self-report questionnaire designed to measure personality pathology as advocated in the fifth edition, Section III of Diagnostic and Statistical Manual of Mental Disorders (DSM-5), are already demonstrated in general population samples, but need replication in clinical samples. In 240 Flemish inpatients, we examined the factor structure of the PID-5 by means of exploratory structural equation modeling. Additionally, we investigated differences in PID-5 higher order domain scores according to gender, age and educational level, and explored convergent and discriminant validity by relating the PID-5 with the Dimensional Assessment of Personality Pathology-Basic Questionnaire and by comparing PID-5 scores of inpatients with and without a DSM-IV categorical personality disorder diagnosis. Our results confirmed the original five-factor structure of the PID-5. The reliability and the convergent and discriminant validity of the PID-5 proved to be adequate. Implications for future research are discussed.

    To assess the reliability and construct validity of the Personality Inventory for DSM-5 Brief Form (PID-5-BF) among adolescents, 877 Italian high school students were administered the PID-5-BF. Participants were administered also the Measure of Disordered Personality Functioning (MDPF) as a criterion measure. In the full sample, Cronbach's alpha values for the PID-5-BF scales ranged from .59 (Detachment) to .77 (Psychoticism); in addition, all PID-5-BF scales showed mean interitem correlation values in the .22 to .40 range. Cronbach's alpha values for the PID-5-BF total score was .83 (mean interitem r = .16). Although 2-month test-retest reliability could be assessed only in a small (n = 42) subsample of participants, all PID-5-BF scale scores showed adequate temporal stability, as indexed by intraclass r values ranging from .78 (Negative Affectivity) to .97 (Detachment), all ps <.001. Exploratory structural equation modeling analyses provided at least moderate support for the a priori model of PID-5-BF items. Multiple regression analyses showed that PID-5-BF scales predicted a nonnegligible amount of variance in MDPF Non-Cooperativeness, adjusted R(2) = .17, p < .001, and Non-Coping scales, adjusted R(2) = .32, p < .001. Similarly, the PID-5-BF total score was a significant predictor of both MDPF Non-Coping, and Non-Cooperativeness scales.

    OBJECTIVE: to develop indicators for the nursing outcome Swallowing Status and the respective conceptual and operational definitions validated by experts and in a clinical setting among patients after having experienced a stroke. METHOD: methodological study with concept analysis and content and clinical validations. The Content Validation Index was verified for the scores assigned by 11 experts to indicators. Two pairs of nurses assessed 81 patients during the clinical validation: one pair used an instrument with definitions and the other used an instrument without definitions. The resulting assessments were compared using Intraclass Correlation Coefficient, Friedman's test, and Minimal Important Difference calculation. RESULTS: All the indicators, with the exception of the indicator Ability to bring food to mouth, presented Content Validation Index above 0.80. The pair using the instrument with definitions presented an Intraclass Correlation Coefficient above 0.80 for all the indicators and similarity was found in all the assessments, according to the Minimal Important Difference calculation. The pair using the instrument without definitions presented a low coefficient (ρ<0.75) for all the indicators. CONCLUSION: the results showed that greater uniformity and accuracy was achieved by the pair of nurses using the conceptual and operational definitions for the indicators of the nursing outcome Swallowing Status.

    Background Although Perceived Stress Scale (PSS, Cohen, Kamarack & Mermelstein, 1983) has been validated and widely used in many domains, there is still no validation in sports by comparing athletes and non-athletes and examining related psychometric indices. Purpose The purpose of this study was to examine the measurement invariance of PSS between athletes and non-athletes, and examine construct validity and reliability in the sports contexts. Methods Study 1 sampled 359 college student-athletes (males = 233; females = 126) and 242 non-athletes (males = 124; females = 118) and examined factorial structure, measurement invariance and internal consistency. Study 2 sampled 196 student-athletes (males = 139, females = 57, Mage = 19.88 yrs, SD = 1.35) and examined discriminant validity and convergent validity of PSS. Study 3 sampled 37 student-athletes to assess test-retest reliability of PSS. Results Results found that 2-factor PSS-10 fitted the model the best and had appropriate reliability. Also, there was a measurement invariance between athletes and non-athletes; and PSS positively correlated with athletic burnout and life stress but negatively correlated with coping efficacy provided evidence of discriminant validity and convergent validity. Further, the test-retest reliability for PSS subscales was significant (r = .66 and r = .50). Discussion It is suggested that 2-factor PSS-10 can be a useful tool in assessing perceived stress either in sports or non-sports settings. We suggest future study may use 2-factor PSS-10 in examining the effects of stress on the athletic injury, burnout, and psychiatry disorders. PMID:27994983

    This study examines the validity of the measures of verbal and nonverbal working memory on the Stanford-Binet Fifth Edition (SB5). The validity evidence included Rasch-based, criterion-referenced item mapping, correlations with other clinical measures of memory, and prediction of reading and mathematics scores. The item mapping clearly demonstrates a parallel between increasing item difficulty and a progression of item characteristics that placed increasing demands on verbal and nonverbal working memory. The higher correlations of the SB5 verbal and nonverbal working memory subtests with other measures of verbal and nonverbal memory, respectively, and lower correlations with nonverbal and verbal memory measures, respectively, clearly show convergent and divergent validity. The higher correlations between SB5 verbal working memory and reading skills and between SB5 nonverbal memory and mathematics skills are consistent with past research.

    Abstract Objective: to construct an instrument for the assessment of graduates of undergraduate nursing courses and to validate this instrument through the consensus of specialists. Method: methodological study. In order to elaborate the instrument, documental analysis and a literature review were undertaken. Validation took place through use of the Delphi Conference, between September 2012 and September 2013, in which 36 specialists from Brazilian Nursing participated. In order to analyze reliability, the Cronbach alpha coefficient, the item/total correlation, and the Pearson correlation coefficient were calculated. Results: the instrument was constructed with the participation of specialist nurses representing all regions of Brazil, with experience in lecturing and research. The first Delphi round led to changes in the first instrument, which was restructured and submitted to another round, with a response rate of 94.44%. In the second round, the instrument was validated with a Cronbach alpha of 0.75. Conclusion: the final instrument possessed three dimensions related to the characterization of the graduate, insertion in the job market, and evaluation of the professional training process. This instrument may be used across the territory of Brazil as it is based on the curricular guidelines and contributes to the process of regulation of the quality of the undergraduate courses in Nursing.

    ABSTRACT Objective: evaluate the practicality, acceptability and the floor and ceiling effects, estimate the reliability and verify the convergent construct's validity with the instrument called the Heart Valve Disease Impact on daily life (IDCV) of the valve disease in patients with mitral and or aortic heart valve disease. Method: data was obtained from 86 heart valve disease patients through 3 phases: a face to face interview for a socio-demographic and clinic characterization and then other two done through phone calls of the interviewed patients for application of the instrument (test and repeat test). Results: as for the practicality and acceptability, the instrument was applied with an average time of 9,9 minutes and with 110% of responses, respectively. Ceiling and floor effects observed for all domains, especially floor effect. Reliability was tested using the test - repeating pattern to give evidence of temporal stability of the measurement. Significant negative correlations with moderate to strong magnitude were found between the score of the generic question about the impact of the disease and the scores of IDCV, which points to the validity of the instrument convergent construct. Conclusion: the instrument to measure the impact of valve heart disease on the patient's daily life showed evidence of reliability and validity when applied to patients with heart valve disease.

    The rapid construction of hardware-in-the-loop simulation(HILS) system and validation of the flight control approach for the TianHang eXperimental(THX) rocket are investigated. Firstly, the six degree of freedom simulation system is accomplished using MATLAB/Simulink, and the simulation models are classified and masked into various blocks by their functions. And then, the integrated design of testing and debugging of the flight control devices and the HILS system construction is proposed based on the dSPACE real-time platform. The test and calibration of the gyroscope and rudder system and the flight control code automatically generation are carried out, and various leve's of HILS are achieved. Finally, the optimal linear quadratic regulator with the integrate part is proposed for the three channels of the flight vehicle. The numerical and HILS results demonstrated the effective performance of the proposed control approach. As the control system design implements only on the MATLAB/Simulink platform, a large of repeated work is overleaped. Therefore, the rapid construction of the HILS is accomplished, and the flight control design and validation period is decreased, which implies the remarkable value in engineering application.

    2014-01-01

    Background The development, validation, and psychometric properties of the Wake Forest Physician Trust Scale (WFPTS)-equivalent instrument for Chinese patients were investigated. Material/Methods We approached 3442 randomly selected outpatients at 3 Shanghai (China) general hospitals, treated ≥2 times per year by the same physician, for participation between November 2008 and December 2008. A Chinese version of the WFPTS (C-WFPTS) was prepared and administered to eligible and consenting patients, and subjected to validity assessment using 5 patient behaviors: (1) recommendation of the physician; (2) occurrence of dispute; (3) seeking a second opinion; (4) treatment adherence; and (5) consideration of switching physicians. Results A total of 352 (M: F, 149: 203; mean age, 40.67±17.31 years; age range, 14–94 years) consenting and eligible patients were included in the analysis. The unidimensionality and internal consistency of C-WFPTS was confirmed (Cronbach’s α=0.833). Physician trust correlated significantly with physician satisfaction (r=0.73, P<0.001) and all 5 behaviors (1: r=0.453, 2: r=0.209, 3: r=0.406, 4: r=0.444, 5: r=0.471; P<0.001 for all), indicating validity and predictive validity, respectively. Patient trust increased significantly with increasing age and physician visits (P>0.05), but was not related to gender, birthplace, or insurance type. Conclusions C-WFPTS has good psychometric properties, reliability, and validity for the evaluation of patient trust in the patient-physician relationship, and thereby provides an essential tool for the characterization of patient-physician relationships in China, which is necessary for healthcare reform.

    With increasing economic globalization, including health care, it is important to use standardized outcome measures applicable to a broad spectrum of patients in a wide array of countries. The purpose of this study was to verify construct and content validity and reliability of the Chinese version of the Patient-rated Wrist Evaluation Questionnaire (PRWE-Hong Kong version). The PRWE was translated into Chinese, and face validity was established by inviting experts and patients to participate in the panel review of the questionnaire. A correlation field study was performed using a convenience sample of 47 patients with wrist injuries. Patients were assessed at baseline and six weeks after the initial measurement. The following measures were taken: the Chinese version of the PRWE and the Medical Outcome Short Form (36) Health Survey (SF-36), Visual Analogue Scale (VAS) for pain, active wrist range of motion, grip strength, and the Jebsen Hand Function Test. Statistical analysis consisted of Pearson correlation coefficients (convergent validity), factor analysis (content validity), paired t-test (convergent validity), and the Cronbach alpha (internal consistency). Clinically relevant correlations existed between "Pain at rest" and the VAS "resting pain" (r=0.785, p<0.0001) as well as between "Pain on repeated wrist movement" and the VAS "exertion pain" (r=0.872, p<0.0001). The "Physical Component Summary" of the SF-36 was found significantly correlated with the PRWE function subset total score (r=-0.618, p<0.0001), and the PRWE total score (r=-0.645, p<0.0001). The specific function subset score also correlated with the wrist flexion range (r=-0.308, p<0.0001) and the grip strength (r=-0.488, p=0.035). Two factors were found that accounted for 61% of the variance. The Cronbach alpha coefficients ranged from 0.7805 to 0.9502, indicating that the internal consistency of the questionnaire items was sound and reliable. Positive correlations between the wrist ranges of

    2017-01-01

    It is crucial to replicate the micromechanical milieu of native tissues to achieve efficacious tissue engineering and regenerative therapy. In this study, we introduced an innovative loading platform, EQUicycler, that utilizes a simple, yet effective, and well-controlled mechanism to apply physiologically relevant homogenous mechanical equiaxial strain on three-dimensional cell-embedded tissue scaffolds. The design of EQUicycler ensured elimination of gripping effects through the use of biologically compatible silicone posts for direct transfer of the mechanical load to the scaffolds. Finite Element Modeling (FEM) was created to understand and to quantify how much applied global strain was transferred from the loading mechanism to the tissue constructs. In vitro studies were conducted on various cell lines associated with tissues exposed to equiaxial mechanical loading in their native environment. In vitro results demonstrated that EQUicycler was effective in maintaining and promoting the viability of different musculoskeletal cell lines and upregulating early differentiation of osteoprogenitor cells. By utilizing EQUicycler, collagen fibers of the constructs were actively remodeled. Residing cells within the collagen construct elongated and aligned with strain direction upon mechanical loading. EQUicycler can provide an efficient and cost-effective tool to conduct mechanistic studies for tissue engineered constructs designed for tissue systems under mechanical loading in vivo.

    2012-05-01

    Virtual reality (VR) assessment paradigms have the potential to address the limited ecological validity of pen and paper measures of executive function (EF) and the pragmatic and reliability issues associated with functional measures. To investigate the ecological validity and construct validity of a newly developed VR measure of EF, the Virtual Library Task (VLT); a real life analogous task--the Real Library Task (RLT); and five neuropsychological measures of EF were administered to 30 patients with traumatic brain injury (TBI) and 30 healthy Controls. Significant others for each participant also completed the Dysexecutive Questionnaire (DEX), which is a behavioral rating scale of everyday EF. Performances on the VLT and the RLT were significantly positively correlated indicating that VR performance is similar to real world performance. The TBI group performed significantly worse than the Control group on the VLT and the Modified Six Elements Test (MSET) but the other four neuropsychological measures of EF failed to differentiate the groups. Both the MSET and the VLT significantly predicted everyday EF suggesting that they are both ecologically valid tools for the assessment of EF. The VLT has the advantage over the MSET of providing objective measurement of individual components of EF.

    2016-01-01

    Objective To evaluate the reliability of concurrent flare identification using 3 methods (patient, rheumatologist and Disease Activity Score (DAS)28 criteria), and construct validity of candidate items representing the Outcome Measures in Rheumatology Clinical Trials (OMERACT) RA Flare Core Domain Set. Methods Candidate flare questions and legacy measures were administered at consecutive visits to Canadian Early Arthritis Cohort (CATCH) patients between November 2011 and November 2014. The American College of Rheumatology (ACR) core set indicators were recorded. Concordance to identify flares was assessed using the agreement coefficient. Construct validity of flare questions was examined: convergent (Spearman's r); discriminant (mean differences between flaring/non-flaring patients); and consequential (proportions with prior treatment reductions and intended therapeutic change postflare). Results The 849 patients were 75% female, 81% white, 42% were in remission/low disease activity (R/LDA), and 16–32% were flaring at the second visit. Agreement of flare status was low–strong (κ's 0.17–0.88) and inversely related to RA disease activity level. Flare domains correlated highly (r's≥0.70) with each other, patient global (r's≥0.66) and corresponding measures (r's 0.49–0.92); and moderately highly with MD and patient-reported joint counts (r's 0.29–0.62). When MD/patients agreed the patient was flaring, mean flare domain between-group differences were 2.1–3.0; 36% had treatment reductions prior to flare, with escalation planned in 61%. Conclusions Flares are common in rheumatoid arthritis (RA) and are often preceded by treatment reductions. Patient/MD/DAS agreement of flare status is highest in patients worsening from R/LDA. OMERACT RA flare questions can discriminate between patients with/without flare and have strong evidence of construct and consequential validity. Ongoing work will identify optimal scoring and cut points to identify RA flares. PMID

    2013-01-01

    This article describes the development and validation of a new instrument, the scale (SCAP) which measures community participation (CP) and socio-political participation (SPP). The sample consists of 756 participants in Málaga, residents whose average age is 38.78 years old (SD = 13.96) and of whom 58.5% are women. The results endorse the psychometric qualities of the instrument. We present descriptive analysis of the items, the dimensionality of the scale and its internal consistency. The external evidence of validity shows positive and statistically significant correlations with sense of community and empowerment, variables theoretically related to participation. A confirmatory factor analysis confirms the two-dimensional structure (CP and SPP). Further analysis show a higher CP in women. This instrument extends the quantitative research on citizen participation.

    2013-11-01

    The aim of this descriptive study, carried out at a public university, was to design, develop, and validate a distance learning module on intramuscular premedication antisepsis. The content was introduced in the Modular Object-Oriented Dynamic Learning Environment, based on the Systematic Model for Web-Based Training projects. Ten nurses and information technologists at work consented to participate, in compliance with ethical guidelines, and answered a questionnaire to validate the Virtual Learning Environment. The educational aspects of the environment interface were mostly evaluated as "excellent," whereas the assessment of didactic resources indicated interactivity difficulties. It is concluded that distance learning is an important tool for the teaching of premedication antisepsis. To ensure its effectiveness, appropriate methods and interactive devices must be used.

    Given changing and subjective aspects of quality of life, the current assessment scales are often encompassing and not very adapted for older people. Thus, the present validation study has several objectives: 1) To elaborate a specific measure of the quality of life of older people, given the characteristics and problems of this population; 2) To propose a simple scale to use for any health care professional and fast passation to encourage the inclusion of such measures in the framework of a comprehensive care of the elderly; 3) To validate this scale in a large cohort of retired older farmers. This scale resulted in 14 items illustrating the various dimensions of quality of life of older people. It was then proposed for validation in a large cohort of retired elderly farmers of 65 years and over, and living at home. After exploratory factor analysis of subjects' responses to the EQVPA, five items were extracted explaining 48.8% of the total variance. Its internal consistency was satisfactory (Cronbach's alpha=0.72). The five items permitted to assess daily and social activities in environment, social and familial relationships, physical and functional health and mental health. The results showed that quality of life is significantly correlated with greater life satisfaction, more social support and social network, higher level of subjective health, lower level of functional impairments, lower level of anxious and depressive symptoms, and lower level of routinization. Validation of the tools such as EQVPA seems important for the prevention and preservation of the quality of life of older people.

    In this article, we describe the construction and validation of a laparoscopic trainer using an iPhone 5 and a plastic document holder case. The abdominal cavity was simulated with a clear plastic document holder case. On 1 side of the case, 2 holes for entry of laparoscopic instruments were drilled. We added a window to place the camera of the iPhone, which works as our camera of the trainer. Twenty residents carried out 4 tasks using the iPhone Trainer and a physical laparoscopic trainer. The time of all tasks were analyzed with a simple paired t test. The construction of the trainer took 1 hour, with a cost of

    The construct and concurrent validity of the Thera-Band Perceived Exertion Scale for Resistance Exercise with elastic bands (EB) was examined. Twenty subjects performed two separate sets of 15 repetitions of both frontal and lateral raise exercise over two sessions. The criterion variables were myoelectric activity and heart rate. One set was performed with an elastic band grip width that permitted 15 maximum repetitions in the selected exercise, and another set was performed with a grip width 50% more than the 15RM grip. Following the final repetition of each set, active muscle (AM) and overall body (O) ratings of perceived exertion (RPE) were collected from the Thera-Band® resistance exercise scale and the OMNI-Resistance Exercise Scale of perceived exertion with Thera-Band® resistance bands (OMNI-RES EB). Construct validity was established by correlating the RPE from the OMNI-RES EB with the Thera-Band RPE scale using regression analysis. The results showed significant differences (p ≤ 0.05) in myoelectric activity, heart rate, and RPE scores between the low- and high-intensity sets. The intraclass correlation coefficient for active muscles and overall RPE scale scores was 0.67 and 0.58, respectively. There was a positive linear relationship between the RPE from the OMNI-RES EB and the Thera-Band scale. Validity coefficients for the RPE AM were r2 = 0.87 and ranged from r2 = 0.76 to 0.85 for the RPE O. Therefore, the Thera-Band Perceived Exertion Scale for Resistance Exercise can be used for monitoring elastic band exercise intensity. This would allow the training dosage to be better controlled within and between sessions. Moreover, the construct and concurrent validity indicates that the OMNI-RES EB measures similar properties of exertion as the Thera-Band RPE scale during elastic resistance exercise. Key points This new resistance intensity scale is an appropriate and valid tool for assessing perceived exertion during strength training with elastic bands

    A common approach for determining musical competence is to rely on information about individuals' extent of musical training, but relying on musicianship status fails to identify musically untrained individuals with musical skill, as well as those who, despite extensive musical training, may not be as skilled. To counteract this limitation, we developed a new test battery (Profile of Music Perception Skills; PROMS) that measures perceptual musical skills across multiple domains: tonal (melody, pitch), qualitative (timbre, tuning), temporal (rhythm, rhythm-to-melody, accent, tempo), and dynamic (loudness). The PROMS has satisfactory psychometric properties for the composite score (internal consistency and test-retest r>.85) and fair to good coefficients for the individual subtests (.56 to.85). Convergent validity was established with the relevant dimensions of Gordon's Advanced Measures of Music Audiation and Musical Aptitude Profile (melody, rhythm, tempo), the Musical Ear Test (rhythm), and sample instrumental sounds (timbre). Criterion validity was evidenced by consistently sizeable and significant relationships between test performance and external musical proficiency indicators in all three studies (.38 to.62, p<.05 to p<.01). An absence of correlations between test scores and a nonmusical auditory discrimination task supports the battery's discriminant validity (-.05, ns). The interrelationships among the various subtests could be accounted for by two higher order factors, sequential and sensory music processing. A brief version of the full PROMS is introduced as a time-efficient approximation of the full version of the battery.

    2011-01-01

    Background Fibromyalgia (FM) is a prevalent and disabling disorder characterized by a history of widespread pain for at least three months. Pain is considered a complex experience in which affective and cognitive aspects are crucial for prognosis. The aim of this study is to assess the importance of pain-related psychological constructs on function and pain in patients with FM. Methods Design Multicentric, naturalistic, one-year follow-up study. Setting and study sample. Patients will be recruited from primary care health centres in the region of Aragon, Spain. Patients considered for inclusion are those aged 18-65 years, able to understand Spanish, who fulfil criteria for primary FM according to the American College of Rheumatology, with no previous psychological treatment. Measurements The variables measured will be the following: main variables (pain assessed with a visual analogue scale and with sphygmomanometer and general function assessed with Fibromyalgia Impact Questionnaire, and), psychological constructs (pain catastrophizing, pain acceptance, mental defeat, psychological inflexibility, perceived injustice, mindfulness, and positive and negative affect), and secondary variables (sociodemographic variables, anxiety and depression assessed with Hospital Anxiety and Depression Scale, and psychiatric interview assessed with MINI). Assessments will be carried at baseline and at one-year follow-up. Main outcome Pain Visual Analogue Scale. Analysis The existence of differences in socio-demographic, main outcome and other variables regarding pain-related psychological constructs will be analysed using Chi Square test for qualitative variables, or Student t test or variance analysis, respectively, for variables fulfilling the normality hypothesis. To assess the predictive value of pain-related psychological construct on main outcome variables at one-year follow-up, use will be made of a logistic regression analysis adjusted for socio-demographic and clinical

    Individual radiosensitivity is an individual characteristic associated with an increased reaction to ionizing radiation. The purpose of our work is to establish a dose-response curve useful to classify individuals as radiosensitive or radioresistant. Thus, a dose-response curve was constructed by measuring in vitro responses to increasing doses (0 to 8 Gy) of gamma radiation in the comet assay. The obtained curve fit well with a linear equation in the range of 0 to 8 Gy. The overall dose-response curve was constructed for percent DNA in tail, as a measure of the genetic damage induced by irradiation. To probe the goodness of the constructed curve, a validation study was carried out with whole blood from two donors in a blind study. Results show that, for the two applied doses (2 and 6 Gy), the obtained values fit well inside the interval of confidence of the curve. In conclusion, our results demonstrate the usefulness of the comet assay in determining individual responses to defined doses of gamma radiation. The standard dose-response curve constructed may be used to detect individuals departing from reference values.

    Background The purpose of this study was to test the discriminant validity of ISHLT PGD grades in terms of lung injury biomarker profiles and survival. Methods The study samples consisted of a multicenter prospective cohort study for the biomarker analysis and a 450 patient cohort study for the mortality analyses. PGD was defined according to ISHLT consensus at 24, 48 and 72 hours after transplantation. We compared the changes in plasma markers of acute lung injury between PGD grades using longitudinal data models. To test predictive validity, we compared differences in the 30-day mortality and long-term survival according to PGD grade. Results PGD grade 3 demonstrated greater differences between plasma ICAM-1, protein C, and PAI-1 levels than did PGD grades 0-2 at 24, 48, and 72 hours after lung transplantation (p<0.05 for each). Grade 3 had the highest 30-day (test for trend p<0.001) and overall mortality (log rank p<0.001), with PGD grades 1 and 2 demonstrating intermediate risks of mortality. The ability to discriminate both 30 day and overall mortality improved as the time of grading moved away from the time of transplantation (test for trend p<0.001). Conclusions The ISHLT grading system has good discriminant validity, based on plasma markers of lung injury and mortality. Grade 3 PGD was associated with the most severely altered plasma biomarker profile and the worst outcomes, regardless of the time point of grading. PGD grade at 48 and 72 hours discriminated mortality better than PGD grade at 24 hours. PMID:20655249

    High density oligonucleotide microarrays have been used on Plasmodium vivax field isolates to estimate whole genome expression. However, no microarray platform has been experimentally optimized for studying the transcriptome of field isolates. In the present study, we adopted both bioinformatics and experimental testing approaches to select best optimized probes suitable for detecting parasite transcripts from field samples and included them in designing a custom 15K P. vivax microarray. This microarray has long oligonucleotide probes (60mer) that were in-situ synthesized onto glass slides using Agilent SurePrint technology and has been developed into an 8X15K format (8 identical arrays on a single slide). Probes in this array were experimentally validated and represents 4180 P. vivax genes in sense orientation, of which 1219 genes have also probes in antisense orientation. Validation of the 15K array by using field samples (n=14) has shown 99% of parasite transcript detection from any of the samples. Correlation analysis between duplicate probes (n=85) present in the arrays showed perfect correlation (r(2)=0.98) indicating the reproducibility. Multiple probes representing the same gene exhibited similar kind of expression pattern across the samples (positive correlation, r≥0.6). Comparison of hybridization data with the previous studies and quantitative real-time PCR experiments were performed to highlight the microarray validation procedure. This array is unique in its design, and results indicate that the array is sensitive and reproducible. Hence, this microarray could be a valuable functional genomics tool to generate reliable expression data from P. vivax field isolates.

To date, there is no systematic ethogram of the cynomolgus monkey (Macaca fascicularis) in a free enclosure. In a field observation of 6012 subjects, 107 distinct behaviors of M. fascicularis were preliminarily described. 83 of these behaviors were then independently validated through a randomized cohort and classified into 12 behavioral categories. 53 of these behaviors were then selected to accurately reflect the daily mundane activity of the species in a free enclosure. These findings systematically document the behavior of M. fascicularis in a free enclosure for use in further investigations.

    The 14-item Chalder Fatigue Scale (CFS) is widely used, while the 11-item version is seldom to be found in current research in mainland China. The objectives of the present study is to compare the reliability and construct validity between these two versions and to confirm which may be better for the mainland Chinese setting. Based on a cross-sectional health survey with a constructive questionnaire, 1887 individuals aged 18 years or above were selected. Socio-demographic, health-related, gynecological data were collected, and 11-item and 14-item Chalder Fatigue Scale (CFS) were used to assess fatigue. Confirmatory factor analysis and exploratory structural equation modeling (ESEM) were performed to test the fit of models of the two versions. Confirmatory factor analysis of the two versions of CFS did not support the two-factor theorized models. In addition, a three-factor ESEM model of the 11-item version, but not the 14-item version, showed better factor structure and fitness than the other models examined. Both the versions had good internal consistency reliability and a satisfactory internal consistency (Ω = 0.78–0.96, omega coefficient indicates the internal consistency reliability) was obtained from the optimal model. This study provided evidence for satisfactory reliability and structural validity for the three-factor model of the 11-item version, which was proven to be superior to the 14-item version for this data.

    The factor structure, reliability, and construct validity of an abbreviated version of the Revised Dimensions of Temperament Survey (DOTS-R) were evaluated across Black, Hispanic, and White early adolescents. Primary caregivers reported on 5 dimensions of temperament for 4,701 children. Five temperament dimensions were identified via maximum likelihood exploratory factor analysis and were labeled flexibility, general activity level, positive mood, task orientation, and sleep rhythmicity. Multigroup mean and covariance structures analysis provided partial support for strong factorial invariance across these racial/ethnic groups. Mean level comparisons indicated that relative to Hispanics and Blacks, Whites had higher flexibility, greater sleep regularity, and lower activity. They also reported higher positive mood than Blacks. Blacks, relative to Hispanics, had higher flexibility and lower sleep regularity. Construct validity was supported as the 5 temperament dimensions were significantly correlated with externalizing problems and socioemotional competence. This abbreviated version of the DOTS-R could be used across racial/ethnic groups of early adolescents to assess significant dimensions of temperament risk that are associated with mental health and competent (healthy) functioning.

    The Inventory of Callous and Unemotional Traits (ICU), developed to assess callous/unemotional (CU) traits, has recently experienced increased attention in light of the proposal to add a CU specifier to the conduct disorder diagnosis in DSM-5. In a sample of 70 at-risk adolescents (ages 13-17 years) in the foster care system who received a contemplative intervention program, the present study placed the ICU within a nomological network of correlates, including anxiety, depression, hopefulness, loneliness, and physiological measures of stress (e.g., cortisol). The findings offered some support for the ICU's construct validity, including significant negative associations with measures of compassion toward others. Nevertheless, unexpected substantial positive correlations emerged with multiple measures of psychological distress, raising questions concerning other aspects of the ICU's construct validity. Taken together, results of the current study suggest that rather than assessing a dearth of all major emotions as implied by its name and some previous descriptions, the ICU may be heavily saturated with negative emotionality and global maladjustment.

    Background The KINDL questionnaire is frequently used to evaluate quality of life (QOL) and the impacts of health conditions on children's everyday living. The objectives of this study were to assess the reproducibility and construct validity of the Serbian KINDL for QOL assessments in healthy children and adolescents. Methods Five hundred and sixty-four healthy children and adolescents completed the KINDL. Reproducibility was analyzed using the intraclass correlation coefficient (ICC). Confirmatory factor analysis (CFA) was performed to assess the structure of the KINDL - construct validity. Results The intraclass correlation coefficients ranged from 0.03 to 0.84 for the subscales and total score. A second order CFA model as originally hypothesized was tested: items (24), primary factors (six subscales), and one secondary factor (QOL). The fit indexes derived from a CFA failed to yield appropriate fit between the data and the hypothesized model. Conclusion Majority of the subscales and total KINDL possess appropriate reproducibility for group comparisons. However, a CFA failed to confirm the structure of the original measurement model, indicating that the Serbian version should be revised before wider use for QOL assessments in healthy children and adolescent.

Design Baseline and 12-month follow-up assessments conducted across the course of a 12-month exercise program. Setting University research community. Participants Older healthy adults (N=179; mean ± SD age, 66.43±5.67y) at baseline; 145 were retained at follow-up. Interventions Not applicable. Main Outcome Measures LL-FDI and functional performance measures. Results Factor analyses confirmed the factor structure of the abbreviated LL-FDI, and all subscales met minimal criteria for temporal invariance. Significant correlations also were found between functional limitations subscales and an array of physical function performance measures, supporting the scale’s construct validity. Conclusions The abbreviated LL-FDI with some modifications appears to be temporally invariant in community-dwelling older adults. Additionally, moderate relationships between functional limitations and functional performance provide further support for these being conceptually distinct constructs. PMID:21458777

    Science education has undergone many revisions since it was permanently embedded in the country's educational curriculum at the end of the 19th century. Some of these revisions occurred as a direct result of the No Child Left Behind Act (NCLB). This legislation placed more accountability on schools than ever before by requiring that all students pass a series of standardized tests (USDE, 2010). High schools in Mississippi require four areas of standardized testing: English II, Algebra I, U.S. History, and Biology I (Wroten, 2008). The focus of this study is the Biology I Subject Area Test. In an effort to determine the validity of that test, this study explores the importance of the Mississippi Biology I content standards according to the importance ratings and frequency of use ratings by science professionals in Mississippi. The science professionals surveyed for this study were high school science teachers, college science professors and scientists in their professional settings. The science professionals' importance ratings were compared to the importance ratings placed on the content strands by the Mississippi Biology I Subject Area Test. To further determine the test's validity, it is also compared to the National Science Education Standards.

    2015-02-01

    The validity of a Dutch self-report inventory of dyslexia was ascertained in two samples of students. Six biographical questions, 20 general language statements and 56 specific language statements were based on dyslexia as a multi-dimensional deficit. Dyslexia and non-dyslexia were assessed with two criteria: identification with test results (Sample 1) and classification using biographical information (both samples). Using discriminant analyses, these criteria were predicted with various groups of statements. All together, 11 discriminant functions were used to estimate classification accuracy of the inventory. In Sample 1, 15 statements predicted the test criterion with classification accuracy of 98%, and 18 statements predicted the biographical criterion with classification accuracy of 97%. In Sample 2, 16 statements predicted the biographical criterion with classification accuracy of 94%. Estimations of positive and negative predictive value were 89% and 99%. Items of various discriminant functions were factor analysed to find characteristic difficulties of students with dyslexia, resulting in a five-factor structure in Sample 1 and a four-factor structure in Sample 2. Answer bias was investigated with measures of internal consistency reliability. Less than 20 self-report items are sufficient to accurately classify students with and without dyslexia. This supports the usefulness of self-assessment of dyslexia as a valid alternative to diagnostic test batteries.

    2015-01-01

    Attention-deficit/hyperactivity disorder (ADHD) is the most widely used children's mental health diagnosis today, but the validity of the diagnosis is controversial, for instance, because it might conceal relational and ecological dimensions of restlessness. We invited parents and professionals from one local community in western Norway to participate in cooperative group discussions on how to conceptualize and understand children's restlessness. We carried out a thematic and reflexive analysis of the cooperative group discussions on ADHD and children's restlessness, and present findings related to three ecological levels inspired by Bronfenbrenner's ecological systems model. At the level of the individual, restlessness was discussed as individual trait, as the expectation to be seen and heard, and as a result of traumatization. At the level of dyad, group or family, restlessness was discussed as a relational phenomenon and as parents' problems. At the level of community, restlessness was discussed as lack of cooperation and lack of structures or resources. Our findings show how contextualized and cooperative reflexivity can contribute to more valid understandings of children's restlessness, and how cooperative inquiry can stimulate reflections about solidarity and sustainability in relation to adult's actions.

    The objective of this study is to determine the ability of the GEARS scale (Global Evaluative Assessment of Robotic Skills) to differentiate individuals with different levels of experience in robotic surgery, as a fundamental validation. This is a cross-sectional study that included three groups of individuals with different levels of experience in robotic surgery (expert, intermediate, novice) their performance were assessed by GEARS applied by two reviewers. The difference between groups was determined by Mann-Whitney test and the consistency between the reviewers was studied by Kendall W coefficient. The agreement between the reviewers of the scale GEARS was 0.96. The score was 29.8 ± 0.4 to experts, 24 ± 2.8 to intermediates and 16 ± 3 to novices, with a statistically significant difference between all of them (p < 0.05). All parameters from the scale allow discriminating between different levels of experience, with exception of the depth perception item. We conclude that the scale GEARS was able to differentiate between individuals with different levels of experience in robotic surgery and, therefore, is a validated and useful tool to evaluate surgeons in training.

    Landfarming biodegradation is a strategy used by the petrochemical industry to reduce pollutants in petroleum-contaminated soil. We constructed 2 metagenomic libraries from landfarming soil in order to determine the pathway used for mineralization of benzene and to examine protein expression of the bacteria in these soils. The DNA of landfarm soil, collected from Ilhéus, BA, Brazil, was extracted and a metagenomic library was constructed with the Copy Control(TM) Fosmid Library Production Kit, which clones 25-45-kb DNA fragments. The clones were selected for their ability to express enzymes capable of cleaving aromatic compounds. These clones were grown in Luria-Bertani broth plus L-arabinose, benzene, and chloramphenicol as induction substances; they were tested for activity in the catechol cleavage pathway, an intermediate step in benzene degradation. Nine clones were positive for ortho-cleavage and one was positive for meta-cleavage. Protein band patterns determined by SDS-polyacrylamide gel electrophoresis differed in bacteria grown on induced versus non-induced media (Luria-Bertani broth). We concluded that the DNA of landfarm soil is an important source of genes involved in mineralization of xenobiotic compounds, which are common in gasoline and oil spills. Metagenomic library allows identification of non-culturable microorganisms that have potential in the bioremediation of contaminated sites.

    While observing six simulated construction tasks in the field, trained analysts recorded arm, trunk and leg postures categorically with two fixed-interval observational protocols. Observations were compared to measurements obtained with an electronic postural assessment system coupled with video analysis. The electronic postural assessment system consisted of electronic inclinometers to measure upper arm posture, knee flexion and trunk flexion, coveralls to house the inclinometer wiring, and an eletrogoniometric system to measure trunk lateral bending and twisting. Video analysis included frozen-frame analysis that corresponded to the moment of observation and simulated real-time analysis. Measurements were made on five male participants who each performed three tasks representative of construction laborers' work. Agreement among the observational and reference methods was generally high, although significant differences in measured frequency of exposure existed for knee flexion, trunk lateral bending and trunk twisting. The results suggest that, under appropriate conditions, discrete observations can be used to obtain reasonably accurate estimates of exposure frequency for broad categories of certain body postures.

    Self-reported disability related to neck pain can be measured using general health questionnaires. The validity of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) in patients with nonspecific chronic neck pain (CNP) in a tertiary outpatient rehabilitation setting is unknown. This study investigates construct validity of the SF-36 in these patients using 16 a-priori formulated hypotheses. Ninety-one patients admitted for rehabilitation completed the SF-36 before the rehabilitation program. SF-36 domain scores of patients with CNP were compared with general population reference values and standardized differences were calculated. For both the SF-36 physical and the mental component summary (PCS and MCS), differences between primary and tertiary care setting, men and women, age groups, litigants and nonlitigants, patients with and without compensation, and with ≥3 versus≤2 concomitant complaints were analyzed using independent t-tests. Differences between PCS and MCS scores were analyzed using a paired t-test. Twelve hypotheses were not rejected and four were rejected. All SF-36 domain scores were significantly lower than the general population references values. The domain scores 'role physical', 'bodily pain', 'vitality', 'social functioning,' and 'role emotional' were relevantly (≥1 SD) lower. SF-36-PCS and SF-36-MCS scores were significantly lower in tertiary care. The SF-36-PCS score was significantly lower for patients with workers compensation and patients with at least three concomitant complaints. The SF-36-MCS score was significantly lower for the age group of at least 39 years. The SF-36 has good construct validity and can be used to measure self-reported general health in patients with nonspecific CNP in outpatient tertiary rehabilitation.

    Objective Scales used to measure selected social-cognitive beliefs and motives for physical activity were tested among boys and girls. Methods Covariance modeling was applied to responses obtained from large multi-ethnic samples of students in the fifth and sixth grades. Results Theoretically and statistically sound models were developed, supporting the factorial validity of the scales in all groups. Multi-group longitudinal invariance was confirmed between boys and girls, overweight and normal weight students, and non-Hispanic black and white children. The construct validity of the scales was supported by hypothesized convergent and discriminant relationships within a measurement model that included correlations with physical activity (MET • min/day) measured by an accelerometer. Conclusions Scores from the scales provide valid assessments of selected beliefs and motives that are putative mediators of change in physical activity among boys and girls, as they begin the understudied transition from the fifth grade into middle school, when physical activity naturally declines.

    The aim of this study was to develop and describe a wheelchair mobility performance test in wheelchair basketball and to assess its construct validity and reliability. To mimic mobility performance of wheelchair basketball matches in a standardised manner, a test was designed based on observation of wheelchair basketball matches and expert judgement. Forty-six players performed the test to determine its validity and 23 players performed the test twice for reliability. Independent-samples t-tests were used to assess whether the times needed to complete the test were different for classifications, playing standards and sex. Intraclass correlation coefficients (ICC) were calculated to quantify reliability of performance times. Males performed better than females (P < 0.001, effect size [ES] = -1.26) and international men performed better than national men (P < 0.001, ES = -1.62). Performance time of low (≤2.5) and high (≥3.0) classification players was borderline not significant with a moderate ES (P = 0.06, ES = 0.58). The reliability was excellent for overall performance time (ICC = 0.95). These results show that the test can be used as a standardised mobility performance test to validly and reliably assess the capacity in mobility performance of elite wheelchair basketball athletes. Furthermore, the described methodology of development is recommended for use in other sports to develop sport-specific tests.

    Objective: Assessment of social skills is a necessary requirement to develop and evaluate the effectiveness of cognitive and behavioral interventions. This paper reports the cultural adaptation and psychometric properties of the Farsi version of the social skills rating system-secondary students form (SSRS-SS) questionnaire (Gresham and Elliot, 1990), in a normative sample of secondary school students. Methods: A two-phase design was used that phase 1 consisted of the linguistic adaptation and in phase 2, using cross-sectional sample survey data, the construct validity and reliability of the Farsi version of the SSRS-SS were examined in a sample of 724 adolescents aged from 13 to 19 years. Results: Content validity index was excellent, and the floor/ceiling effects were low. After deleting five of the original SSRS-SS items, the findings gave support for the item convergent and divergent validity. Factor analysis revealed four subscales. Results showed good internal consistency (0.89) and temporal stability (0.91) for the total scale score. Conclusion: Findings demonstrated support for the use of the 27-item Farsi version in the school setting. Directions for future research regarding the applicability of the scale in other settings and populations of adolescents are discussed. PMID:25053964

    2011-09-01

    This study analyzes the process of producing a situational plan according to a benchmark from the philosophy of language and argumentation theory. The basic approach used in the analysis was developed by Carlos Matus. Specifically, the study seeks to identify the inherent argumentative structure and patterns in the situational explanation and regulatory design in a plan's operations, taking argumentative approaches from pragma-dialectics and informal logic as the analytical parameters. The explanation of a health problem is used to illustrate the study. Methodologically, the study is based on the existing literature on the subject and case analyses. The study concludes with the proposition that the use of the specific references means introducing greater rigor into both the analysis of the validity of causal arguments and the design of proposals for interventions, in order for them to be more conclusive in achieving a plan's objectives.

    Lactobacilli are widespread in natural environments and are increasingly being investigated as potential health modulators. In this study, we have adapted the broad-host-range vector pNZ8048 to express the mCherry protein (pRCR) to expand the usage of the mCherry protein for analysis of gene expression in Lactobacillus. This vector is also able to replicate in Streptococcus pneumoniae and Escherichia coli. The usage of pRCR as a promoter probe was validated in Lactobacillus acidophilus by characterizing the regulation of lactacin B expression. The results show that the regulation is exerted at the transcriptional level, with lbaB gene expression being specifically induced by co-culture of the L. acidophilus bacteriocin producer and the S. thermophilus STY-31 inducer bacterium.

    Recently, there has been a lot of interest in characterising the connectivity of resting state brain networks. Most of the literature uses functional connectivity to examine these intrinsic brain networks. Functional connectivity has well documented limitations because of its inherent inability to identify causal interactions. Dynamic causal modelling (DCM) is a framework that allows for the identification of the causal (directed) connections among neuronal systems — known as effective connectivity. This technical note addresses the validity of a recently proposed DCM for resting state fMRI – as measured in terms of their complex cross spectral density – referred to as spectral DCM. Spectral DCM differs from (the alternative) stochastic DCM by parameterising neuronal fluctuations using scale free (i.e., power law) forms, rendering the stochastic model of neuronal activity deterministic. Spectral DCM not only furnishes an efficient estimation of model parameters but also enables the detection of group differences in effective connectivity, the form and amplitude of the neuronal fluctuations or both. We compare and contrast spectral and stochastic DCM models with endogenous fluctuations or state noise on hidden states. We used simulated data to first establish the face validity of both schemes and show that they can recover the model (and its parameters) that generated the data. We then used Monte Carlo simulations to assess the accuracy of both schemes in terms of their root mean square error. We also simulated group differences and compared the ability of spectral and stochastic DCMs to identify these differences. We show that spectral DCM was not only more accurate but also more sensitive to group differences. Finally, we performed a comparative evaluation using real resting state fMRI data (from an open access resource) to study the functional integration within default mode network using spectral and stochastic DCMs. PMID:25463471

    Artificial microRNA (amiRNA) technology utilizes microRNA (miRNA) biogenesis pathway to produce artificially selected small RNAs using miRNA gene backbone. It provides a feasible strategy for inducing loss of gene function, and has been applied in functional genomics study, improvement of crop quality and plant virus disease resistance. A big challenge in amiRNA applications is the unpredictability of silencing efficacy of the designed amiRNAs and not all constructed amiRNA candidates would be expressed effectively in plant cells. We and others found that high efficiency and specificity in RNA silencing can be achieved by designing amiRNAs with perfect or almost perfect sequence complementarity to their targets. In addition, we recently demonstrated that Agrobacterium-mediated transient expression system can be used to validate amiRNA constructs, which provides a simple, rapid and effective method to select highly expressible amiRNA candidates for stable genetic transformation. Here, we describe the methods for design of amiRNA candidates with perfect or almost perfect base-pairing to the target gene or gene groups, incorporation of amiRNA candidates in miR168a gene backbone by one step inverse PCR amplification, construction of plant amiRNA expression vectors, and assay of transient expression of amiRNAs in Nicotiana benthamiana through agro-infiltration, small RNA extraction, and amiRNA Northern blot.

    The authors conducted 4 studies to construct a multidimensional measure of perceptions of organization personality. Results of the first 2 studies suggest that (a) 5 broad factors are sufficient to capture the structure of organization personality perceptions, (b) real-world organizations differ on personality profiles, and (c) personality trait inferences are related to organizational attraction. Results of a 3rd study suggest that personality trait inferences assessed in 1 sample are related lo ratings of organizational attractiveness by a 2nd sample. Finally, results of a 4th study suggest that the measure is sensitive to experimental manipulations of organizational descriptions. Implications and suggestions for the use of this measure in future research are discussed.

    The purpose of this study was to substantiate the usefulness of the tasks on two music-based assessments in providing information about music cognition among people with dementia and to more fully understand the nature of this construct and its relationship to general cognition. Individuals with dementia (N = 50) received 3 evaluations: the Mini-Mental State Exam (MMSE), the MBECF, and the RMST. Results of the study revealed significant correlations between the MMSE and both music-based assessments. A pattern of correlations between the MMSE and the subsets of tasks contained in both music-based assessments showed that while there are strong relationships between music and general cognition, that there also is uniqueness to the melodic, singing and rhythmic aspects of music cognition.

    2012-04-01

    In environmental observations and laboratory visualization both large scale flow components like currents, jets, vortices, waves and a fine structure are registered (different examples are given). The conventional mathematical modeling both analytical and numerical is directed mostly on description of energetically important flow components. The role of a fine structures is still remains obscured. A variety of existing models makes it difficult to choose the most adequate and to estimate mutual assessment of their degree of correspondence. The goal of the talk is to give scrutiny analysis of kinematics and dynamics of flows. A difference between the concept of "motion" as transformation of vector space into itself with a distance conservation and the concept of "flow" as displacement and rotation of deformable "fluid particles" is underlined. Basic physical quantities of the flow that are density, momentum, energy (entropy) and admixture concentration are selected as physical parameters defined by the fundamental set which includes differential D'Alembert, Navier-Stokes, Fourier's and/or Fick's equations and closing equation of state. All of them are observable and independent. Calculations of continuous Lie groups shown that only the fundamental set is characterized by the ten-parametric Galilelian groups reflecting based principles of mechanics. Presented analysis demonstrates that conventionally used approximations dramatically change the symmetries of the governing equations sets which leads to their incompatibility or even degeneration. The fundamental set is analyzed taking into account condition of compatibility. A high order of the set indicated on complex structure of complete solutions corresponding to physical structure of real flows. Analytical solutions of a number problems including flows induced by diffusion on topography, generation of the periodic internal waves a compact sources in week-dissipative media as well as numerical solutions of the same

  11. Construction and validation of a measure of integrative well-being in seven languages: The Pemberton Happiness Index

    2013-01-01

    Purpose We introduce the Pemberton Happiness Index (PHI), a new integrative measure of well-being in seven languages, detailing the validation process and presenting psychometric data. The scale includes eleven items related to different domains of remembered well-being (general, hedonic, eudaimonic, and social well-being) and ten items related to experienced well-being (i.e., positive and negative emotional events that possibly happened the day before); the sum of these items produces a combined well-being index. Methods A distinctive characteristic of this study is that to construct the scale, an initial pool of items, covering the remembered and experienced well-being domains, were subjected to a complete selection and validation process. These items were based on widely used scales (e.g., PANAS, Satisfaction With Life Scale, Subjective Happiness Scale, and Psychological Well-Being Scales). Both the initial items and reference scales were translated into seven languages and completed via Internet by participants (N = 4,052) aged 16 to 60 years from nine countries (Germany, India, Japan, Mexico, Russia, Spain, Sweden, Turkey, and USA). Results Results from this initial validation study provided very good support for the psychometric properties of the PHI (i.e., internal consistency, a single-factor structure, and convergent and incremental validity). Conclusions Given the PHI’s good psychometric properties, this simple and integrative index could be used as an instrument to monitor changes in well-being. We discuss the utility of this integrative index to explore well-being in individuals and communities. PMID:23607679

    Research on progress monitoring has almost exclusively focused on student behavior and not on teacher practices. This article presents the development and validation of a new teacher observational assessment (Classroom Strategies Scale) of classroom instructional and behavioral management practices. The theoretical underpinnings and empirical basis for the instructional and behavioral management scales are presented. The Classroom Strategies Scale (CSS) evidenced overall good reliability estimates including internal consistency, interrater reliability, test-retest reliability, and freedom from item bias on important teacher demographics (age, educational degree, years of teaching experience). Confirmatory factor analyses (CFAs) of CSS data from 317 classrooms were carried out to assess the level of empirical support for (a) a 4 first-order factor theory concerning teachers' instructional practices, and (b) a 4 first-order factor theory concerning teachers' behavior management practice. Several fit indices indicated acceptable fit of the (a) and (b) CFA models to the data, as well as acceptable fit of less parsimonious alternative CFA models that included 1 or 2 second-order factors. Information-theory-based indices generally suggested that the (a) and (b) CFA models fit better than some more parsimonious alternative CFA models that included constraints on relations of first-order factors. Overall, CFA first-order and higher order factor results support the CSS-Observer Total, Composite, and subscales. Suggestions for future measurement development efforts are outlined.

    Drug-polymer miscibility is one of the fundamental prerequisite for the successful design and development of amorphous solid dispersion formulation. The purpose of the present work is to provide an example of the theoretical estimation of drug-polymer miscibility and solubility on the basis of Flory-Huggins (F-H) theory and experimental validation of the phase diagram. The F-H interaction parameter, χ d-p, of model system, aceclofenac and Soluplus, was estimated by two methods: by melting point depression of drug in presence of different polymer fractions and by Hildebrand and Scott solubility parameter calculations. The simplified relationship between the F-H interaction parameter and temperature was established. This enabled us to generate free energy of mixing (ΔG mix) curves for varying drug-polymer compositions at different temperatures and finally the spinodal curve. The predicted behavior of the binary system was evaluated through X-ray diffraction, differential scanning calorimetry, and in vitro dissolution studies. The results suggest possibility of employing interaction parameter as preliminary tool for the estimation of drug-polymer miscibility.

    The Five-Factor Narcissism Inventory (FFNI) is a new self-report measure that was developed to assess traits associated with grandiose and vulnerable narcissism from a Five-factor model (FFM) perspective. In a sample of undergraduates (N = 283), the relations among the FFNI scales, grandiose and vulnerable dimensions, and an array of relevant criteria were examined including self- and informant reports of the Big Five domains, measures of the Dark Triad, ratings of the interpersonal circumplex, externalizing and internalizing behaviors and symptoms, and romantic and attachment styles. The FFNI grandiose and vulnerable dimensions demonstrated good convergent and criterion validity. The FFNI grandiose and vulnerable dimensions manifested converging (e.g., disagreeableness, low love/communion, psychopathy, Machiavellianism, Ludus/Manic love styles) and diverging (e.g., neuroticism, extraversion, dominance, externalizing, internalizing, attachment anxiety) relations in a manner largely consistent with predictions. The FFNI joins the Pathological Narcissism Inventory as a measure that can simultaneously assess both grandiose and vulnerable dimensions of narcissism.

    The aim of this work is to study the unidimensional and multidimensional nature of creativity when assessed through divergent thinking tasks, as proposed in Torrance's battery (Torrance Creative Thinking Test, TTCT). This battery is made up of various tasks with verbal and figurative content, aimed at estimating the level of creativity according to the dimensions or cognitive functions of fluency, flexibility, originality and elaboration of the individuals' ideas. This work used a sample of 595 Portuguese students from 5th and 6th grade. The results of confirmatory factor analysis reveals that the unidimensional model (a general factor of creativity) and the model of factors as a function of the cognitive dimensions of creativity, based on task content, do not fit well. The model with the best fit has a hierarchical factor structure, in which the first level comprises the factors for each of the subtests applied and the second level includes verbal or figurative content. The difficulty to verify the structural validity of the TTCT is noted, and the need for further studies to achieve, in practice, better individual creativity scores.

    Purpose Middle Eastern (ME) population is rapidly growing in the US but cannot be easily identified in cancer registry or other databases for epidemiological research. The purpose of this study was to develop a list of common Middle Eastern surnames and validate it by linking with a cancer registry incidence files. Methods Surnames and place of birth in the Middle East were obtained from various sources. After exclusion of the non-specific entries, the final combined list included 49,610 surnames and was matched with the California Cancer Registry incidence file for 1988-2003. Results Overall, 1.4% of all registered cases were positively identified as ME that is similar to the proportion of ME population in California. Two third of the identified cases had known place of birth in the Middle East and of those, 70% were non-Arabs. The sensitivity of the list in detecting ME birth in men and women are 91% and 86%, respectively. The positive predictive values for men and women are 72% and 65%. The specificity and negative predictive values are universally over 99 percent. Conclusion The high accuracy reported for this Middle Eastern surname list (MESL) makes it a valuable tool for epidemiological studies of this ethnic population. PMID:18023539

    2016-01-01

    The character of construction projects exposes front-line workers to dangers and accidents. Safety climate has been confirmed to be a predictor of safety performance in the construction industry. This study aims to explore the underlying mechanisms of the relationship between multilevel safety climate and safety performance. An integrated model was developed to study how particular safety climate factors of one level affect those of other levels, and then affect safety performance from the top down. A questionnaire survey was administered on six construction sites in Vietnam. A total of 1030 valid questionnaires were collected from this survey. Approximately half of the data were used to conduct exploratory factor analysis (EFA) and the remaining data were submitted to structural equation modeling (SEM). Top management commitment (TMC) and supervisors’ expectation (SE) were identified as factors to represent organizational safety climate (OSC) and supervisor safety climate (SSC), respectively, and coworkers’ caring and communication (CCC) and coworkers’ role models (CRM) were identified as factors to denote coworker safety climate (CSC). SEM results show that OSC factor is positively related to SSC factor and CSC factors significantly. SSC factor could partially mediate the relationship between OSC factor and CSC factors, as well as the relationship between OSC factor and safety performance.

The findings imply that a positive safety culture should be established both at the organizational level and the group level.

    The character of construction projects exposes front-line workers to dangers and accidents. Safety climate has been confirmed to be a predictor of safety performance in the construction industry. This study aims to explore the underlying mechanisms of the relationship between multilevel safety climate and safety performance. An integrated model was developed to study how particular safety climate factors of one level affect those of other levels, and then affect safety performance from the top down. A questionnaire survey was administered on six construction sites in Vietnam. A total of 1030 valid questionnaires were collected from this survey. Approximately half of the data were used to conduct exploratory factor analysis (EFA) and the remaining data were submitted to structural equation modeling (SEM). Top management commitment (TMC) and supervisors' expectation (SE) were identified as factors to represent organizational safety climate (OSC) and supervisor safety climate (SSC), respectively, and coworkers' caring and communication (CCC) and coworkers' role models (CRM) were identified as factors to denote coworker safety climate (CSC). SEM results show that OSC factor is positively related to SSC factor and CSC factors significantly. SSC factor could partially mediate the relationship between OSC factor and CSC factors, as well as the relationship between OSC factor and safety performance. CSC factors partially mediate the relationship between OSC factor and safety performance, and the relationship between SSC factor and safety performance. The findings imply that a positive safety culture should be established both at the organizational level and the group level. Efforts from all top management, supervisors, and coworkers should be provided to improve safety performance in the construction industry.

    This article examines the influence of the Millon Clinical Multiaxial Inventory (MCMI) as a clinical and research instrument beyond the borders of the United States. The MCMI's theoretical and empirical grounding, its alignment with the Diagnostic and Statistical Manual of Mental Disorders (DSM), and scales that can be interpreted both categorically and dimensionally, are the primary features that make the test attractive. We begin with studies that evaluated the construct equivalence of the different language adaptations. Data from the most widely researched non English-language forms (Danish, Dutch, and Spanish) show excellent comparability with Millon's original. Nevertheless, significant problems were noted in efforts to create clinical groups that would allow for equivalence of diagnostic accuracy when using the cutoff scores. Although dimensional aspects of the scale scores were not affected by this, the adapted measures might show attenuated diagnostic accuracy compared with Millon's original. Next, we present MCMI studies conducted in clinical settings to document where the adapted tests have made their greatest impact in the international literature. A wide variety of clinical applications demonstrated broad utility, and given the high number of issues addressed, we think Millon's influence will certainly stand the test of time in different domains and settings.

  2. Latent structure of a two-dimensional model of antisocial personality disorder: construct validation and taxometric analysis.

    Indicators from three different self-report measures-the Psychological Inventory of Criminal Thinking Styles (PICTS), the Levenson Self-Report Psychopathy (LSRP) scale, and the Antisocial Features (ANT) scale of the Personality Assessment Inventory-were organized into two dimensions, proactive and reactive, and subjected to construct validation and taxometric analysis in 637 male medium and maximum security inmates. Using three nonredundant and relatively independent taxometric procedures, mean above minus below a cut (MAMBAC), maximum eigenvalue (MAXEIG), and latent mode factor analysis (L-Mode), consistent evidence of dimensional latent structure was discerned for the proactive and reactive dimensions of antisociality, both of which correlated moderately with a measure of antisocial personality disorder. It is reasoned that the two-dimensional model may eventually be capable of bridging the gap between childhood aggression and adult criminality as well as provide guidance to clinicians working with criminal offenders.

    In 2 studies, we assessed the construct validity of the Italian version of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) version 2.0. In Study 1, we administered the MSCEIT together with measures of crystallized and fluid intelligence, personality, and affect. In Study 2, we administered the MSCEIT together with indexes of dispositional coping, emotion regulation strategies, alexithymia, state-trait anxiety, depression, and depressive rumination. We evaluated the factorial structure of the MSCEIT with a confirmatory factor analysis model using data combined from Study 1 and 2. The results confirm that the MSCEIT Italian version satisfactorily discriminates emotional intelligence ability from crystallized and fluid intelligence, personality, and affect, and exhibits significant correlations with various psychological well-being criteria. Furthermore, data from both studies confirm that the factorial structure of MSCEIT is consistent with the theory on which it is based, although it was difficult to rule out alternative structures.

    Background Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease that often causes disabling dyspnea. In IPF and other lung diseases, patient-reported outcomes (PROs)—questionnaires designed to gather information from the patient's perspective—can determine whether therapies affect dyspnea or other outcomes meaningful to patients. Before a PRO can be used confidently as an outcome measure in a longitudinal trial, studies must demonstrate the PRO's ability to capture change over time in the target population. Our goal in this study was to examine whether the UCSD Shortness of Breath Questionnaire does so in patients with IPF. Methods We used data from the Sildenafil Trial of Exercise Performance in Idiopathic Pulmonary Fibrosis (STEP-IPF) to perform analyses that examined associations between UCSD scores and five external measures (anchors) at baseline and over time. Anchors included the Activity domain from St. George's Respiratory Questionnaire (SGRQ-A), the Physical Functioning domain from the SF-36 (SF36-PF), forced vital capacity (FVC), diffusing capacity of the lung for carbon monoxide (DLCO), and distance walked during a timed walk test (6MWD). Linear regression models were used to examine relationships between UCSD scores and anchors over time. Results At baseline, UCSD scores were weakly correlated with percent predicted FVC (−0.21, p=0.005) and percent predicted DLCO (−0.20, p=0.008), moderately correlated with 6MWD (−0.39, p<0.0001) and strongly correlated with SGRQ-A (0.79, p<0.0001) and SF36-PF (−0.72, p<0.0001). Change over time in UCSD scores was associated with change in FVC (estimate=2.54, standard error [SE]=1.23, p=0.04), SGRQ-A (estimate=7.94, SE=1.11, p<0.0001), SF36-PF (estimate=6.00, SE=1.13, p<0.0001), and 6MWD (estimate=4.23, SE=1.18, p=0.0004) but not DLCO (estimate=0.33, SE=1.33, p=0.80). Conclusions These results support the validity of the UCSD to assess change in dyspnea over time in patients with

  5. Learning in a Physics Classroom Community: Physics Learning Identity Construct Development, Measurement and Validation

    NASA Astrophysics Data System (ADS)

    Li, Sissi L.

    At the university level, introductory science courses usually have high student to teacher ratios which increases the challenge to meaningfully connect with students. Various curricula have been developed in physics education to actively engage students in learning through social interactions with peers and instructors in class. This learning environment demands not only conceptual understanding but also learning to be a scientist. However, the success of student learning is typically measured in test performance and course grades while assessment of student development as science learners is largely ignored. This dissertation addresses this issue with the development of an instrument towards a measure of physics learning identity (PLI) which is used to guide and complement case studies through student interviews and in class observations. Using the conceptual framework based on Etienne Wenger's communities of practice (1998), I examine the relationship between science learning and learning identity from a situated perspective in the context of a large enrollment science class as a community of practice. This conceptual framework emphasizes the central role of identity in the practices negotiated in the classroom community and in the way students figure out their trajectory as members. Using this framework, I seek to understand how the changes in student learning identity are supported by active engagement based instruction. In turn, this understanding can better facilitate the building of a productive learning community and provide a measure for achievement of the curricular learning goals in active engagement strategies. Based on the conceptual framework, I developed and validated an instrument for measuring physics learning identity in terms of student learning preferences, self-efficacy for learning physics, and self-image as a physics learner. The instrument was pilot tested with a population of Oregon State University students taking calculus based

    Compared with conventional histological paraffin blocks, tissue microarray (TMA) represents a "high-throughput tool" that provides rapid results, a time- and cost-effective approach and simultaneous investigation of several tissue samples under the same conditions. Given the large number of cases of dogs affected with mammary tumors, the complexity of these tumors and their similarity with breast cancer in women, this study aimed to validate a low-cost modified method to construct TMAs for canine mammary tumor analysis using immunomarkers. Carcinoma cases were selected from canine mammary carcinomas in mixed tumors (CMT) because this tumor type is the most heterogeneous among the histopathological types of mammary tumors observed in female dogs. Through a histopathological examination, tumor representativity was compared between conventional sections and histological sections obtained from the TMA block; both were stained with hematoxylin and eosin. An immunohistochemistry analysis was performed to compare the percentages of immunoreactive cells obtained in whole tissue sections versus those obtained from sections from the TMA block. Streptavidin-biotin peroxidase complex and anti-PCNA, anti-vimentin and anti-pancytokeratin antibodies were used. Statistical analysis consisted of the nonparametric Friedman's test (p≤0.05) and descriptive statistical analysis. Histopathological analysis showed tumor representativity in all TMA cores selected for the study. There was no difference between the immunohistochemical analysis of mammary tumors using conventional histological sections or sections obtained from a single 1-mm-diameter TMA core, regardless of the marker used: PCNA (p=0.279), pancytokeratin (p=0.243) and vimentin (p=0.967). The results did not change even when the means of any number of cores were compared among each other and with the conventional histological section: PCNA (p=0.413), pancytokeratin (p=0.177) and vimentin (p=1.0). Therefore, this study

    The present research validated the construct and criterion validities of the Cooperative and Competitive Personality Scale (CCPS) in a social dilemma context. The results from three studies supported the notion that cooperativeness and competitiveness are two independent dimensions, challenging the traditional view that they are two ends of a single continuum. First, confirmatory factor analyses revealed that a two-factor structure fit the data significantly better than a one-factor structure. Moreover, cooperativeness and competitiveness were either not significantly correlated (Studies 1 and 3) or only moderately positively correlated (Study 2). Second, cooperativeness and competitiveness were differentially associated with Schwartz's Personal Values. These results further supported the idea that cooperativeness and competitiveness are two distinct constructs. Specifically, the individuals who were highly cooperative emphasized self-transcendent values (i.e., universalism and benevolence) more, whereas the individuals who were highly competitive emphasized self-enhancement values (i.e., power and achievement) more. Finally, the CCPS, which adheres to the trait perspective of personality, was found to be a useful supplement to more prevalent social motive measures (i.e., social value orientation) in predicting cooperative behaviors. Specifically, in Study 2, when social value orientation was controlled for, the CCPS significantly predicted cooperative behaviors in a public goods dilemma (individuals who score higher on cooperativeness scale contributed more to the public goods). In Study 3, when social value orientation was controlled for, the CCPS significantly predicted cooperative behaviors in commons dilemmas (individuals who score higher on cooperativeness scale requested fewer resources from the common resource pool). The practical implications of the CCPS in conflict resolution, as well as in recruitment and selection settings, are discussed.

    The Asbestos NESHAP requires facility owners and/or operators involved in demolition and renovation activities to control emissions of particulate asbestos to the outside air because no safe concentration of airborne asbestos has ever been established. The primary method used to control asbestos emissions is to adequately wet the Asbestos Containing Material (ACM) with a wetting agent prior to, during and after demolition/renovation activities. The purpose of the document is to provide guidance to asbestos inspectors and the regulated community on how to determine if friable ACM is adequately wet as required by the Asbestos NESHAP.

    Data from a developmental assessment comprised of 9 short answer mathematics tasks were validated using classical and three-faceted Rasch measurement methods. Field test data from a mixed age elementary school sample (N=280) were analyzed. Descriptive statistics on scores from the overall scale and two subdomains indicated improved performance with age. The data showed better fit with a two-factor model corresponding with the subdomain structure (Bentler's CFI=.94), than a one factor model (CFI=.87). The inter-factor correlation was.76. Convergent validity coefficients of scores with scaled scores of the Stanford AchievementTest mathematics battery ranged from.28 to.47; internal consistency reliability of the total and subdomain scores ranged from.87 to.89, respectively; and median inter-rater reliability was.75. On average, persons, tasks and raters showed acceptable fit with the three-facet Rasch model. Rasch logit difficulties of tasks suggested an ordered scale structure, although tasks tended to have high difficulty levels. The original and calibrated task ordering was consistent at the extreme ends of the scale. Gaps identified on the Rasch item map suggested a need for additional task construction. Conceptual and procedural differences in each technique are considered in deciding future improvements to the scale.

    This study tested the construct validity of a multidimensional ambivalence model of chocolate craving, and examined the concurrent and discriminant validity of the model with respect to chocolate consumption and disordered eating behaviors. The Orientation to Chocolate Questionnaire (OCQ) was administered to 312 university students (79.5% female) along with measures of chocolate consumption and disordered eating. Results supported a three-factor model of chocolate craving incorporating approach and avoidance inclinations and feelings of guilt. These craving dimensions differentially predicted frequency and quantity of chocolate consumption as well as a range of disordered eating behaviors. Chocolate-related guilt was a consistent indicator of dysfunctional eating patterns, but was unrelated to external or functional eating. Approach inclinations positively predicted consumption-oriented eating behaviors and negatively predicted avoidance-oriented behaviors. Active avoidance inclinations facilitated restraint and inhibited frequency of consumption, but were unrelated to quantity consumed. In line with contemporary theories of substance craving, chocolate craving can be conceptualized as a net action disposition resulting from the relative strength of the competing processes underlying indulgence and restraint.

    Objectives To determine the criterion validity of a questionnaire on physical exposures compared to objective measurements at construction and health care sites and to examine exposure variation over several working days. Methods Five hundred ninety-four construction and health care workers answered a baseline questionnaire. The daily activities (standing, moving, sitting, number of steps), postures (inclination of the arm and the trunk), and relative heart rate of 125 participants were recorded continuously over 3–4 working days. At the end of the first measurement day, the participants answered a second questionnaire (workday questionnaire). Results All objective activity measurements had significant correlations to their respective questions. Among health care workers, there were no correlations between postures and relative heart rate and the baseline questionnaire. The questionnaires overestimated the exposure durations. The highest explained variance in the adjusted models with self-reported variables were found for objectively measured sitting (R2 = 0.559) and arm inclination > 60° (R2 = 0.420). Objective measurements over several days showed a higher reliability compared to single day measurements. Conclusions Questionnaires cannot provide an accurate description of mechanical exposures. Objective measurements over several days are recommended in occupations with varying tasks. PMID:27649499

    Understanding individuals' perceptions of colorectal cancer screening (CRCS) is important for developing effective interventions to increase adherence to screening guidelines. Theory-based cognitive and psychosocial constructs have been associated with CRCS in the literature, but few studies have evaluated the psychometric properties of such measures. We hypothesized a correlated four-factor model including CRCS perceived pros, cons, social influence, and self-efficacy. We also examined measurement invariance across subgroups based on gender, race (white; African American), and prior CRCS experience (never; overdue for repeat screening). We used baseline (n=1,250) and 2-week (n=1,036) follow-up survey data from participants in a behavioral intervention trial designed to increase CRCS. Only minor modifications were made to the hypothesized model to improve fit, and the final model was confirmed with a random half of the sample, as well as with follow-up data. Results support the hypothesized unidimensional construct measures and suggest that the items may be appropriate for all subgroups examined. Greater variance in responses to items assessing the perceived cons of CRCS was found among African Americans compared with whites, suggesting that race may moderate the association between perceived cons and CRCS in this sample. Pros, cons, social influence, and self-efficacy are associated with CRCS; therefore, using scales with known psychometric properties strengthens researchers' ability to draw conclusions about group differences and changes over time and to compare their results with other studies. Replication studies in other populations are needed to provide further evidence of construct validity for the scales reported here. PMID:18768488

    The Test of Visuospatial Construction (TVSC), a measure of visuoconstruction that does not rely on upper extremity motor response or written production, was administered to extremely low birth weight (ELBW), late preterm (LPT), and term participants at preschool (n = 355) and kindergarten (n = 265) ages. TVSC showed statistically significant weak-to-moderate positive correlations (age 3: r = .118-.303; age 6: r = .138-.348) with Developmental VMI, Differential Ability Scales-II Copying, Matrices, and Pattern Construction subtests, Baron-Hopkins Board Test, and the Purdue Pegboard. One-way ANOVA indicated ELBW performed worse than Term (p = .044) on visuospatial construction at age 3 with a small-to-medium effect size (d = -0.43). No other statistically significant differences were found at age 3 on the TVSC (ELBW/LPT: p = .608, d = -0.17; LPT/Term: p = .116, d = -0.31). At age 6, ELBW participants performed worse than LPT participants (p = .027) and Term participants (p = .012); LPT participants did not differ from Term participants. Small effect sizes at age 3 (ELBW < LPT, d = -0.17; ELBW < Term, d = -0.43) were notably larger at age 6 (ELBW < LPT, d = -0.42; ELBW < Term, d = -0.53). Important practical differences showing LPT participants performed below Term participants (d = -0.31) at age 3 were no longer evident at age 6 (d = -0.097). These findings provide preliminary evidence of TVSC validity supporting its use to detect neuropsychological impairment and to recommend appropriate interventions in young preterm children.

    Although a few experimental approaches to isolated limb perfusion (ILP) are described in the literature, none of these animal models mimics the clinical perfusion techniques adequately to improve the technique of ILP on the basis of valid preclinical data. Therefore, we developed an ILP setup in rats allowing online monitoring of essential perfusion parameters such as temperature (in perfusate, various tissues, and rectum), pH (perfusate), perfusion pressure, and O(2) concentration (in perfusate, tissue), by a tailor-made data acquisition system. This setup permits close supervision of vital parameters during ILP. Various interdependencies, concerning the flow rate and the pressure of perfusate as well as tissue oxygenation were registered. For the measurement of pO(2) values in the perfusate and in different regions of the perfused hind limb, a novel type of microoptode based on quenching of a fluorescent dye was devised. Stable normothermic (37 degrees C) perfusion conditions were maintained at a constant perfusion pressure in the range of 40-60 mm Hg by administration of the spasmo lytic moxaverine (0.5 mg/mL of perfusate as initial dose) at a perfusate flow rate of 0.5 mL/min for 60 min. At the end of an ILP, there were no signs of tissue damage, neither concerning laboratory data (K(+), myoglobin, creatine kinase, lactic dehydrogenase) nor histopathological criteria. The reported ILP model is not only well suited to investigate the effects of hyperthermia but also to assess the efficacy of new antineoplastic approaches, when nude rats, bearing human tumours in the hind limbs, are used.

    Background The Chinese version of the Activities of Daily Living Rating Scale III (ADLRS-III), which has 10 domains, is commonly used for assessing activities of daily living (ADL) in patients with schizophrenia. However, construct validity (i.e., unidimensionality) for each domain of the ADLRS-III is unknown, limiting the explanations of the test results. Purpose This main purpose of this study was to examine unidimensionality of each domain in the ADLRS-III. We also examined internal consistency and ceiling/floor effects in patients with schizophrenia. Methods From occupational therapy records, we obtained 304 self-report data of the ADLRS-III. Confirmatory factor analysis (CFA) was conducted to examine the 10 one-factor structures. If a domain showed an insufficient model fit, exploratory factor analysis (EFA) was performed to investigate the factor structure and choose one factor representing the original construct. Internal consistency was examined using Cronbach’s alpha (α). Ceiling and floor effects were determined by the percentage of patients with the maximum and minimum scores in each domain, respectively. Results CFA analyses showed that 4 domains (i.e., leisure, picture recognition, literacy ability, communication tools use) had sufficient model fits. These 4 domains had acceptable internal consistency (α = 0.79-0.87) and no ceiling/floor effects, except the leisure domain which had a ceiling effect. The other 6 domains showed insufficient model fits. The EFA results showed that these 6 domains were two-factor structures. Conclusion The results supported unidimensional constructs of the leisure, picture recognition, literacy ability, and communication tool uses domains. The sum scores of these 4 domains can be used to represent their respective domain-specific functions. Regarding the 6 domains with insufficient model fits, we have explained the two factors of each domain and chosen one factor to represent its original construct. Future users may

    There is increased need for efficient computerized methods to collect reliable data on a range of cognitive domains that can be linked to specific brain systems. Such need arises in functional neuroimaging studies, where individual differences in cognitive performance are variables of interest or serve as confounds. In genetic studies of complex behavior, which require particularly large samples, such trait measures can serve as endophenotypes. Traditional neuropsychological tests, based on clinical pathological correlations, are protracted, require extensive training in administration and scoring, and leave lengthy paper trails (double-entry for analysis). We present a computerized battery that takes an average of 1h and provides measures of accuracy and speed on 9 neurocognitive domains. They are cognitive neuroscience-based in that they have been linked experimentally to specific brain systems with functional neuroimaging studies. We describe the process of translating tasks used in functional neuroimaging to tests for assessing individual differences. Data are presented on each test with samples ranging from 139 (81 female) to 536 (311 female) of carefully screened healthy individuals ranging in age from 18 to 84. Item consistency was established with acceptable to high Cronbach alpha coefficients. Inter-item correlations were moderate to high within domain and low to nil across domains, indicating construct validity. Initial criterion validity was demonstrated by sensitivity to sex differences and the effects of age, education and parental education. These results encourage the use of this battery in studies needing an efficient assessment of major neurocognitive domains such as multi-site genetic studies and clinical trials.

    The Braden Scale is the most widely used pressure ulcer risk assessment system in the world. To investigate its construct validity using structural equation modeling (SEM), a secondary analysis of retrospective data of patients admitted to an acute care facility was conducted using the records of 2588 patients who were at risk for pressure ulcers and admitted between January 2013 and December 2013. Data were extracted to an Excel sheet and analyzed, including demographic characteristics (ie, patients age, gender, weight, and disease spectrum), as well as total Braden scores and subscale scores. The SEM was set according to modification indices suggestion. The original Braden Scale model was supported by χ2(9) = 22.854, CFI = 0.902, GFI = 0.974, root mean square error of approximation (RMSEA) = 0.092, indicating inadequate model fit. After modification according to software indices, χ2(2) = 2.052, CFI = 0.999, GFI = 0.999, RMSEA = 0.020 indicated an acceptable fit of the model (final model). The factor loadings of 6 subscales were all significant (P <.001), with .147 for nutrition, .137 for activity, .167 for friction and shear, .825 for sensory perception, .626 for mobility, and .556 for moisture subscale. The nutrition, activity, and friction and shear subscales were corrected to examine their relationships with other Braden Scale subscales (nutrition with activity [φ -0.063], activity with friction/shear [φ 0.136], and nutrition (φ friction/shear [0.159]). The factor loadings ranged from -0.067 to 0.159. These findings suggest the original Braden Scale has inadequate construct validity for acute care patients and that new risk-predicting scales should be designed based on data mining. Second, according to the factor loadings in the SEM, the most important risk factor in the Braden Scale for this patient population is sensory perception, followed by mobility and moisture. This suggests practitioners should pay particular attention to pressure ulcer prevention

    Planetary surface exploration technology over the past few years has seen significant advancements on multiple fronts. Robotic exploration platforms are becoming more sophisticated and capable of embarking on more challenging missions. More unconventional designs, particularly transforming architectures that have multiple modes of locomotion, are being studied. This work explores the capabilities of one such novel transforming rover called the Transforming Roving-Rolling Explorer (TRREx). Biologically inspired by the armadillo and the golden-wheel spider, the TRREx has two modes of locomotion: it can traverse on six wheels like a conventional rover on benign terrain, but can transform into a sphere when necessary to negotiate steep rugged slopes. The ability to self-propel in the spherical configuration, even in the absence of a negative gradient, increases the TRREx's versatility and its concept value. This paper describes construction and testing of a prototype cylindrical TRREx that demonstrates that "actuated rolling" can be achieved, and also presents a dynamic model of this prototype version of the TRREx that can be used to investigate the feasibility and value of such self-propelled locomotion. Finally, we present results that validate our dynamic model by comparing results from computer simulations made using the dynamic model to experimental results acquired from test runs using the prototype.

Data obtained from load cells (inferring joint moments) may aid clinicians in the prescription, alignment and gait rehabilitation of persons with limb loss. Purpose of this study was to assess the accuracy of prosthesis-integrated load cells for routine use in clinical practice. Level ground walking of persons with transtibial amputation was concurrently measured with a commercially-available prosthesis-integrated load cell, a 10-camera motion analysis system, and piezoelectric force plates. Ankle and knee flexion/extension moments were derived and measurement methods were compared via correlation analysis. Pearson correlation coefficients ranged from 0.661 for ankle pronation/supination moments to 0.915 for ankle flexion/extension moments (p<0.001). Root mean squared errors between measurement methods were in the magnitude of 10% of the measured range and were explainable. Differences in results depicted differences between systems in definition and computation of measurement variables. They may not limit clinical use of the load cell, but should be considered when data are compared directly to conventional gait analysis data. Construct validity of the load cell (i.e., ability to measure joint moments in-situ) is supported by the study results. PMID:24603673

    The Interpersonal Theory of Suicide proposes that suicidal behavior is so frightening that in order for an individual to engage in suicidal behavior, desire for suicide must be accompanied by the capability to do so. The capability for suicide is characterized by both a sense of fearlessness about death and elevated physiological pain tolerance. The primary aim of the current project was to reevaluate and revise the Acquired Capability for Suicide Scale (ACSS) and offer a revision to the scale. Expert review of the scale items resulted in retaining seven items assessing fearlessness about death. The recommendation is made to refer to the revised scale as the ACSS-Fearlessness about Death (ACSS-FAD) to reflect its content more specifically. A model with the 7 retained items provided good fit to the data across three independent samples of young adults. Multiple group analyses examining measurement invariance across men and women found that the latent structure of the scale is comparable across gender. Data are also presented demonstrating convergent and discriminant validity for the scale in young adults and an inpatient psychiatric sample. Findings support the viability of the ACSS-FAD, indicating the scale has a replicable factor structure that generalizes across males and females and is substantively related to the construct of fearlessness about death. Taken together, the present work extends our knowledge of the psychometrics of the ACSS-FAD in particular and the nature of fearlessness about death in general. PMID:24274043

    The purpose of this study was to examine the construct and predictive validity of a dynamic assessment (DA) of decoding learning. Students (N = 318) were assessed in the fall of first grade on an array of instruments that were given in hopes of forecasting responsiveness to reading instruction. These instruments included DA as well as one-point-in-time (static) measures of early alphabetic knowledge, rapid automatized naming (RAN), phonemic awareness, oral vocabulary, listening comprehension, attentive behavior, and hyperactive or impulsive behavior. An IQ test was administered in spring of second grade. Measures of reading outcomes administered in spring of first grade were accuracy and fluency of word identification skills and reading comprehension. Factor analysis using principal axis factor extraction indicated that DA loaded on a first factor that also included language abilities and IQ, which the authors refer to as the "language, IQ, and DA" factor. It was relatively distinct from two additional factors: (a) "speeded alphabetic knowledge and RAN" and (b) "task-oriented behavior." A three-level (children nested within classroom; classrooms nested within school) random intercept model with fixed effects predictors suggested that DA differed from word attack in predicting future reading skill and that DA was a significant predictor of responsiveness to instruction, contributing unique variance to end-of-first-grade word identification and reading comprehension beyond that explained by other well-established predictors of reading development.

    2015-10-01

    Test anxiety is a highly prevalent and impairing syndrome. However, research on clinically relevant manifestations of test anxiety and especially on effective treatment components is still very sparse. In the present study we examined the predictive validity of constructs derived from the self-regulative model for evaluation anxiety proposed by Zeidner and Matthews (2007) for discriminating clinical and non-clinical levels of test anxiety. We compared self-report data from 47 clinically test anxious patients with those from 41 healthy university students. Results showed that learning goals, self-concept of abilities, self-incrimination, elaboration and perfectionism were the constructs that independently separated clinical from non-clinical levels of test anxiety, thus providing the strongest discriminant validity even when controlling for an effect of the global severity of mental health problems. These constructs spread across all three domains proposed in the model, thus providing important implications for possible targets of interventions to reduce clinical levels of test anxiety.

  16. Construct validity of the walk ratio as a measure of gait control in people with multiple sclerosis without mobility aids.

    2016-06-01

    Ambulatory limitations are a key component of disability in people with multiple sclerosis (PwMS). Various tools are employed to assess walking performance in PwMS; however, no ideal measure has as yet been attained. In this situation, a walk ratio might be more advantageous compared with other gait measures. The walk ratio, a simple index for describing temporal and spatial co-ordination, denotes the relationship between step length and cadence during walking. Hence, the primary objective of this study was to determine the relationship between the walk ratio and measures of other theoretically related constructs. The walk ratio was studied using the GAITRite™ system (CIR Systems, Inc. Havertown, USA). The study group included 229 PwMS (143 women) and a mean disease duration of 5.8 (SD=7.1) years. The walk ratio score of the total sample was 5.3 (SD=0.8). Significant differences based on the expanded disability status scale (EDSS) scores (F=11.616, P<0.001) were observed between the neurological disability subgroups. Scores of the very mild (EDSS 0-2.0), mild (EDSS 2.5-4.0) and moderate (EDSS 4.5-5.5) groups were 5.5 (SD=0.7), 5.2 (SD=0.7), 4.9 (SD=0.9), respectively. In terms of fall status, the MS fallers demonstrated a significant lower walk ratio compared to the MS non-fallers; 5.1 (SD=0.8) vs. 5.5 (SD=0.7); P<0.001. Modest significant correlation scores were found between walk ratio and ambulation tests. Scores were slightly higher in the short walking tests, timed 25-foot walk and timed up and go tests (Pearson's rho=0.369, 0.364) compared to the 6 and 2-min walk time tests (Pearson's rho=0.344, 0.308). Collectively, the current study supports the construct validity of the walk ratio index in PwMS without mobility aids.

  17. The weight management strategies inventory (WMSI). Development of a new measurement instrument, construct validation, and association with dieting success.

    In an obesogenic environment, people have to adopt effective weight management strategies to successfully gain or maintain normal body weight. Little is known about the strategies used by the general population in daily life. Due to the lack of a comprehensive measurement instrument to assess conceptually different strategies with various scales, we developed the weight management strategies inventory (WMSI). In study 1, we collected 19 weight management strategies from research on self-regulation of food intake and successful weight loss and maintenance, as well as from expert interviews. We classified them under the five main categories of health self-regulation strategies - goal setting and monitoring, prospection and planning, automating behavior, construal, and inhibition. We formulated 93 items. In study 2, we developed the WMSI in a random sample from the general population (N = 658), using reliability and exploratory factor analysis. This resulted in 19 factors with 63 items, representing the 19 strategies. In study 3, we tested the 19-factor structure in a quota (age, gender) sample from the general population (N = 616), using confirmatory factor analysis. A good model fit (CFI = .918; RMSEA = .043) was revealed. Reliabilities and construct validity were high. Positive correlations of most strategies with dieting success and negative correlations of some strategies with body mass index were found among dieters (N = 292). Study 4 (N = 162) revealed a good test-retest reliability. The WMSI assesses theoretically derived, evidence-based, and conceptually different weight management strategies with different scales that have good psychometric characteristics. The scales can also be used for pre- and post measures in intervention studies. The scales provide insights into the general population's weight management strategies and facilitate tailoring and evaluating health communication.

  18. Vascular function assessed by passive leg movement and flow-mediated dilation: initial evidence of construct validity.

    The vasodilatory response to passive leg movement (PLM) appears to provide a novel, noninvasive assessment of vascular function. However, PLM has yet to be compared with the established noninvasive assessment of vascular health, flow-mediated dilation (FMD). Therefore, as an initial evaluation of the construct validity of PLM and upright seated and supine PLM as well as brachial (BA) and superficial femoral (SFA) artery FMDs were performed in 10 young (22 ± 1) and 30 old (73 ± 2) subjects. During upright seated PLM, the peak change in leg blood flow (ΔLBF) and leg vascular conductance (ΔLVC) was significantly correlated with BA (r = 0.57 and r = 0.66) and SFA (r = 0.44 and r = 0.41, ΔLBF and ΔLVC, respectively) FMD. Furthermore, although the relationships were not as strong, the supine PLM response was also significantly correlated with BA (r = 0.38 and r = 0.35) and SFA (r = 0.39 and r = 0.35, ΔLBF and ΔLVC, respectively) FMD. Examination of the young and old separately, however, revealed that significant relationships persisted in both groups only for the upright seated PLM response and BA FMD (young: r = 0.73 and r = 0.77; old: r = 0.35 and r = 0.45, ΔLBF and ΔLVC, respectively). Normalizing FMD for shear rate during PLM abrogated all significant relationships between the PLM and FMD response, suggesting a role for nitric oxide (NO) in these associations. Collectively, these data indicate that PLM, particularly upright seated PLM, likely provides an index of vascular health analogous to the traditional FMD test. Given the relative ease of PLM implementation, these data have important positive implications for PLM as a clinical vascular health assessment.

    One of the agendas for addressing environmental protection in construction is to reduce impacts and make the construction activities more sustainable. This important consideration has generated several research interests within the construction industry, especially considering the construction damaging effects on the ecosystem, such as various forms of environmental pollution, resource depletion and biodiversity loss on a global scale. Using Partial Least Squares-Structural Equation Modeling technique, this study validates environmental sustainability (ES) construct in the context of large construction firms in Malaysia. A cross-sectional survey was carried out where data was collected from Malaysian large construction firms using a structured questionnaire. Results of this study revealed that business innovativeness and new technology are important in determining environmental sustainability (ES) of the Malaysian construction firms. It also established an adequate level of internal consistency reliability, convergent validity and discriminant validity for each of this study's constructs. And based on this result, it could be suggested that the indicators for organisational innovativeness dimensions (business innovativeness and new technology) are useful to measure these constructs in order to study construction firms' tendency to adopt environmental sustainability (ES) in their project execution.

    Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples. To address this gap in the literature, we examined PPI-R's reliability, construct validity and factor structure in non-criminal individuals (N = 227) in Sweden, using a multimethod approach including psychophysiological correlates of empathy for pain. PPI-R construct validity was investigated in subgroups of participants by exploring its degree of overlap with (i) the Psychopathy Checklist: Screening Version (PCL:SV), (ii) self-rated empathy and behavioral and physiological responses in an experiment on empathy for pain, and (iii) additional self-report measures of alexithymia and trait anxiety. The PPI-R total score was significantly associated with PCL:SV total and factor scores. The PPI-R Coldheartedness scale demonstrated significant negative associations with all empathy subscales and with rated unpleasantness and skin conductance responses in the empathy experiment. The PPI-R higher order Self-Centered Impulsivity and Fearless Dominance dimensions were associated with trait anxiety in opposite directions (positively and negatively, respectively). Overall, the results demonstrated solid reliability (test-retest and internal consistency) and promising but somewhat mixed construct validity for the Swedish translation of the PPI-R.

    For a sample of 305 6th, 7th and 8th grade students, of whom 95% was from economically disadvantaged Hispanic families and for whom English was their second language, evidence was sought regarding the reliability and construct validity of scores on a Spanish version of an academic self-concept measure entitled Dimensions of Self-Concept (DOSC), comprising five subscales bearing the same names as those of the five hypothesized constructs that they were intended to operationalize: Level of Aspiration, Anxiety, Academic Interest and Satisfaction, Leadership and Initiative, and Identification versus Alienation. Reliability estimates varying between .72 and .80 were judged to be reasonably satisfactory. Results from oblique factor analysis lent empirical support for the hypothesized constructs of Anxiety, Leadership and Initiative, and Identification versus Alienation. Scores associated with the subscales of Level of Aspiration and Academic Interest and Satisfaction generated a factor interpreted as a fusion of the two constructs of Level of Aspiration and Academic Interest and Satisfaction.

    The purpose of this study was to establish normal thyroglobulin (Tg) reference intervals (RIs) in regions with adequate and more than adequate iodine intake according to the National Academy of Clinical Biochemistry (NACB) guidelines and to investigate the relationships between Tg and other factors.A total of 1317 thyroid disease-free adult subjects (578 men, 739 nonpregnant women) from 2 cities (Guangzhou and Nanjing) were enrolled in this retrospective, observational study. Each subject completed a questionnaire and underwent physical and ultrasonic examination. Serum Tg, thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), Tg antibody (TgAb), and urinary iodine concentration (UIC) were measured. Reference groups were established on the basis of TSH levels: 0.5 to 2.0 and 0.27 to 4.2 mIU/L.The Tg RIs for Guangzhou and Nanjing were 1.6 to 30.0 and 1.9 to 25.8 ng/mL, respectively. No significant differences in Tg were found between genders or among different reference groups. Stepwise linear regression analyses showed that TgAb, thyroid volume, goiter, gender, age, and TSH levels were correlated with Tg.In adults from regions with adequate and more than adequate iodine intake, we found that Tg may be a suitable marker of iodine status; gender-specific Tg RI was unnecessary; there was no difference between Tg RIs in regions with adequate and more than adequate iodine intake; and the TSH criterion for selecting the Tg reference population could follow the local TSH reference rather than 0.5 to 2.0 mIU/L.

    Teaching ethical behavior is an aspect of physical education. The purpose of the study was to present the construction and to estimate validity of a test which assesses physical education students' moral judgment, the Moral Judgment Test in Physical Education. The sample comprised 281 male and female participants (95 in Grades 7 to 9, 92 in Grades 10 to 12, and 94 university students), who completed Lind's Moral Judgment Test and the Moral Judgment Test-PE version. The validity of the latter was assessed using four criteria of Lind's moral theory. Analysis indicated that the Moral Judgment Test-PE had adequate construct validity and correlated positively, although relatively weakly, with the original test, so the new version has sufficient construct validity to be used in physical education.

    We evaluated the construct validity (including responsiveness), reliability, and feasibility of the Pain Squad multidimensional smartphone-based pain assessment application (app) in children and adolescents with cancer, using 2 descriptive studies with repeated measures. Participants (8-18 years) undergoing cancer treatment were drawn from 4 pediatric cancer centers. In study 1, 92 participants self-reported their level of pain twice daily for 2 weeks using the Pain Squad app to assess app construct validity and reliability. In study 2, 14 participants recorded their level of pain twice a day for 1 week before and 2 weeks after cancer-related surgery to determine app responsiveness. Participants in both studies completed multiple measures to determine the construct validity and feasibility of the Pain Squad app. Correlations between average weekly pain ratings on the Pain Squad app and recalled least, average, and worst weekly pain were moderate to high (0.43-0.68). Correlations with health-related quality of life and pain coping (measured with PedsQL Inventory 4.0, PedsQL Cancer Module, and Pain Coping Questionnaire) were -0.46 to 0.29. The app showed excellent internal consistency (α = 0.96). Pain ratings changed because of surgery with large effect sizes between baseline and the first week postsurgery (>0.85) and small effect sizes between baseline and the second week postsurgery (0.13-0.32). These findings provide evidence of the construct validity, reliability, and feasibility of the Pain Squad app in children and adolescents with cancer.

    The construct validity of the Male Role Norms Inventory-Short Form (MRNI-SF) was assessed using a latent variable approach implemented with structural equation modeling (SEM). The MRNI-SF was specified as having a bifactor structure, and validation scales were also specified as latent variables. The latent variable approach had the advantages of separating effects of general and specific factors and controlling for some sources of measurement error. Data (N = 484) were from a diverse sample (38.8% men of color, 22.3% men of diverse sexualities) of community-dwelling and college men who responded to an online survey. The construct validity of the MRNI-SF General Traditional Masculinity Ideology factor was supported for all 4 of the proposed latent correlations with: (a) Male Role Attitudes Scale; (b) general factor of Conformity to Masculine Norms Inventory-46; (c) higher-order factor of Gender Role Conflict Scale; and (d) Personal Attributes Questionnaire-Masculinity Scale. Significant correlations with relevant other latent factors provided concurrent validity evidence for the MRNI-SF specific factors of Negativity toward Sexual Minorities, Importance of Sex, Restrictive Emotionality, and Toughness, with all 8 of the hypothesized relationships supported. However, 3 relationships concerning Dominance were not supported. (The construct validity of the remaining 2 MRNI-SF specific factors-Avoidance of Femininity and Self-Reliance through Mechanical Skills was not assessed.) Comparisons were made, and meaningful differences noted, between the latent correlations emphasized in this study and their raw variable counterparts. Results are discussed in terms of the advantages of an SEM approach and the unique characteristics of the bifactor model. (PsycINFO Database Record

    2004-06-01

    We conducted an observational study of parent-child interaction in home activity settings (routines) of families raising young children with developmental disabilities and problem behavior. Our aim was to empirically investigate the construct validity of coercion in typical but unsuccessful family routines. The long-term goal was to develop an expanded ecological unit of analysis that may contribute to sustainable behavioral family intervention. Ten children with autism and/or mental retardation and their families participated. Videotaped observations were conducted in typical but unsuccessful home routines. Parent-child interaction in routines was coded in real time and sequential analyses were conducted to test hypotheses about coercive processes. Following observation, families were interviewed about the social validity of the construct. Results confirmed the presence of statistically significant, attention-driven coercive processes in routines in which parents were occupied with non-child centered tasks. Results partially confirmed the presence of escape-driven coercive processes in routines in which parent demands are common. Additional analysis revealed an alternative pattern with greater magnitude. Family perspectives suggested the social validity of the construct. Results are discussed in terms of preliminary, partial evidence for coercive processes in routines of families of children with developmental disabilities. Implications for behavioral assessment and intervention design are discussed.

    Edens, John F; McDermott, Barbara E

    2010-03-01

    Although the construct of psychopathy is frequently construed as a unitary syndrome, the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) and its revision, the PPI-R (Lilienfeld & Widows, 2005), are composed of 2 scales, termed Fearless Dominance (FD) and Self-Centered Impulsivity (SCI), which appear to reflect orthogonal dimensions. In this study, we examined the construct validity of the FD and SCI scales of the PPI-R as markers of these constructs with a range of theoretically relevant correlates assessed across multiple domains in a sample of 200 forensic psychiatric inpatients. Results were generally, though not uniformly, consistent with hypothesized relationships: The SCI scale positively and selectively predicted anger and hostility, impulsivity, total psychiatric symptoms, drug abuse or dependence, antisocial behavior, and violence risk, whereas FD predicted anger, depression, anxiety symptoms (negatively), and alcohol abuse or dependence (positively).

    Greenslade, Kathryn J.; Plante, Elena; Vance, Rebecca

    2009-01-01

    Purpose In order to support evidence-based practice, this study served to evaluate the diagnostic accuracy, convergent validity, and divergent validity of the Structured Photographic Expressive Language Test—Preschool: Second Edition (SPELT–P2; J. Dawson, J. A. Eyer, J. Fonkalsrud, 2005) in order to determine whether it can be used as a valid measure for identifying language impairment in preschoolers. Method The SPELT–P2 was administered to 54 children with typically developing language and 42 children with specific language impairment. Results A discriminant analysis revealed good sensitivity (90.6%), good specificity (100%), and good positive and negative likelihood ratios, with a standard score cutoff point of 87 used to determine group membership. Analyses of convergent and divergent validity also supported use of the SPELT–P2 for identifying language impairment in preschoolers. Implications The empirical evidence supports use of the SPELT–P2 as a valid measure for correctly identifying the presence or absence of language impairment in 4- and 5-year-old preschool children.

    Field, Nigel P; Strasser, Judith; Taing, Sopheap; Horiuchi, Shoko; Chhim, Sotheara; Packman, Wendy

    2014-09-30

    This study addressed the validity of the prolonged grief (PG) construct in a Cambodian context. Eighty mothers who lost a young adult daughter stemming from a crowd stampede incident during the annual water festival were interviewed at the six-month post-loss point along with a control group of similarly aged women who were not recently bereaved. Both groups were assessed for PG, PTSD, anxiety, and depression symptoms and well as for the number of distal losses experienced during the Khmer Rouge (KR) regime - knowing that all the women were old enough to have lived through the KR regime. Support for the discriminant validity of PG was shown in a factor analysis in which its core symptoms were distinguished from anxiety, depression, and PTSD symptoms. Also, support was found for its incremental validity as shown in the unique sensitivity of PG in distinguishing the two groups when controlling for the other symptoms. Lastly, a positive relationship was found between the number of distal deaths experienced during the KR regime and PG symptom severity among the group of recently bereaved mothers, providing support for the predictive validity of PG. Implications as well as study limitations are discussed.

    PubMed

    Fiske, Alan Page

    2002-01-01

    Analyzing national and ethnic differences in individualism and collectivism, D. Oyserman, H. M. Coon, and M. Kemmelmeier (2002) showed that small differences in scales or samples produce markedly divergent results, challenging the validity of these constructs. The author examines the following limitations of research on individualism and collectivism: It treats nations as cultures and culture as a continuous quantitative variable; conflates all kinds of social relations and distinct types of autonomy; ignores contextual specificity in norms and values; measures culture as the personal preferences and behavior reports of individuals; rarely establishes the external validity of the measures used; assumes cultural invariance in the meaning of self-reports and anchoring and interpretation of scales; and reduces culture to explicit, abstract verbal knowledge.

    2016-04-01

    A new method of constructing a superleak assembly for use in experiments involving 4He or 3He-4He mixtures at very low temperatures is described. Superleaks are made of a porous medium with very small pores and channels. Superleaks are often incorporated in thermomechanical pumps, superfluid magnetic pumps, dilution refrigerators, and superfluid helium transfer systems. We used several cylindrical pieces of Vycor, a permeable glass with average pore diameter of 40 Å and porosity of 28%, as a candidate to be used in our superleak assembly. Our design is simple and compact. Our superleak assembly can be disassembled and easily reassembled for reuse. We successfully tested and validated this device at temperatures between 1.4 K and 2.7 K. We experienced no superfluid leaks into the surrounding vacuum. We also report that thermal cycling caused no performance degradation. It is our goal to share the design and construction techniques of this new superleak assembly.

    2002-04-01

    The authors examined the usefulness of a self-report measure for elective selection, loss-based selection. optimization, and compensation (SOC) as strategies of life management. The expected 4-factor solution was obtained in 2 independent samples (N = 218, 14-87 years; N = 181, 18-89 years) exhibiting high retest stability across 4 weeks (r(tt) = .74-82). As expected, middle-aged adults showed higher endorsement of SOC than younger and older adults. Moreover, SOC showed meaningful convergent and divergent associations to other psychological constructs (e.g., thinking styles, NEO) and evinced positive correlations with measures of well-being which were maintained after other personality and motivational constructs were controlled for. Initial evidence on behavioral associations involving SOC obtained in other studies is summarized.

    2014-01-01

    Child reports of hope continue to be utilized as predictors of positive adjustment; however, the utilization of the hope construct has not been assessed within the culturally diverse Native American child group. The present study investigated the applicability of the Hope theory among 96 Native American children in the Midwest. Measures included the Children’s Hope Scale and a Hope Interview. Native American children in the current sample appear to conceptualize hope as a way to reach goals as did the children in the normative sample. Results from the factor analysis demonstrate that the factor structure found in the current study was similar to the factor structure found in the standardization sample. Because of the similar Hope theory conceptualization and factor structure, interventions focused on the positive psychology construct of hope may be applicable within a Native American child population.

    Background Self-reported health measures are important indicators used by clinicians and researchers for the evaluation of health interventions, outcome assessment of clinical studies, and identification of health needs to improve resource allocation. However, the application of self-reported health measures relies on developing reliable and valid instruments that are suitable across diverse populations. The main objective of this study is to evaluate the construct validity of the SF-12v.2, an instrument for measuring self-rated physical and mental health, for homeless adults with mental illness. Various interventions have been aimed at improving the health of homeless people with mental illness, and the development of valid instruments to evaluate these interventions is imperative. Study Design We measured self-rated mental and physical health from a quota sample of 575 homeless people with mental illness using the SF-12v2, EQ-5D, Colorado Symptoms Index, and physical/mental health visual analogue scales. We examined the construct validity of the SF-12v2 through confirmatory factor analyses (CFA), and using ANOVA/correlation analyses to compare the SF-12v2 to the other instruments to ascertain discriminant/convergent validity. Results Our CFA showed that the measurement properties of the original SF-12v2 model had a mediocre fit with our empirical data (χ2 = 193.6, df = 43, p < .0001, CFI = 0.85, NFI = 0.83, RMSEA = 0.08). We demonstrate that changes based on theoretical rationale and previous studies can significantly improve the model, achieving an excellent fit in our final model (χ2 = 160.6, df = 48, p < .0001, CFI = 0.95, NFI = 0.95, RMSEA = 0.06). Our CFA results suggest that an alternative scoring method based on the new model may optimize health status measurement of a homeless population. Despite these issues, convergent and discriminant validity of the SF-12v2 (scored based on the original model) was supported through multiple comparisons with other

  16. The Response to Challenge Scale (RCS): The Development and Construct Validity of an Observer-Rated Measure of Children's Self-Regulation.

    PubMed

    Lakes, Kimberley D

    2012-04-01

    In this manuscript, I present an observer-rated measure of child self-regulation, the Response to Challenge Scale (RCS). The RCS was designed to measure children's cognitive, affective, and motor regulation in response to a physical challenge course. 198 children (Kindergarten through fifth grade) were evaluated using the RCS. All children individually completed a challenge course on two separate occasions four months apart. During their completion of the tasks, research-trained observers rated the degree to which children exhibited cognitive, affective, and motor regulation. In a fully-crossed research design, five raters on Occasion 1 and six raters on Occasion 2 rated all children. I examined the RCS within the Generalizability Theory (GT) framework to analyze construct validity (PRS). Results demonstrated that raters are able to distinguish between children's self-regulation in various domains, providing some validity evidence for the RCS, and supporting the theory that self-regulation is a construct that is evidenced in different domains (Baumeister, 1997).

    2009-11-01

    Studies have documented the construct validity of Bornstein and Languirand's (2003) Relationship Profile Test (RPT) in college students, psychotherapy patients, and nursing home residents, but no studies have examined the utility of RPT Destructive Overdependence (DO), Dysfunctional Detachment (DD), and Healthy Dependency (HD) scores in community samples. To fill this gap, we assessed links between RPT scores and theoretically related variables in low income urban women seeking medical services (N = 110), obtaining predicted links between RPT scores and scores on measures of childhood abuse and neglect, adult attachment style, conflict-resolution tactics involving a domestic partner, Axis I symptomatology, and overall quality of life. Comparison of RPT means in this sample with those in Bornstein et al.'s (2003) college student sample yielded differences that were generally in line with expectations. These results support the construct validity of RPT scores in urban women and suggest that the RPT may be a useful index of DO, DD, and HD in this heretofore unexamined population.

    Whereas verbal learning has received considerable attention by cognitive neuropsychology, spatial object learning has been more resistant to study. The paucity of visual learning data has hampered attempts to clarify if visual learning has unique features with specialized neural substrates. In schizophrenia, severe verbal learning impairment has been established, but lack of comparable visual learning measures has thwarted the dissociation of verbal and visual abilities. The Visual Object Learning Test (VOLT) was developed to examine aspects of visual-spatial learning and memory in a manner analogous to available verbal tests. Studies were performed to establish normative performance characteristics, convergent and divergent validity, and the sensitivity of the VOLT to detection of individual differences in normal (through sex and age) and pathologic variability (through persons with schizophrenia). The results indicated excellent internal consistency, convergent and divergent validity, and sensitivity to the effects of aging and pathology. Persons with schizophrenia were impaired in both learning and retention. The authors conclude that memory impairment in schizophrenia may not be specific to verbal learning.

    Macarthur, Roy; Feinberg, Max; Bertheau, Yves

    2010-01-01

    A method is presented for estimating the size of uncertainty associated with the measurement of products derived from genetically modified organisms (GMOs). The method is based on the uncertainty profile, which is an extension, for the estimation of uncertainty, of a recent graphical statistical tool called an accuracy profile that was developed for the validation of quantitative analytical methods. The application of uncertainty profiles as an aid to decision making and assessment of fitness for purpose is also presented. Results of the measurement of the quantity of GMOs in flour by PCR-based methods collected through a number of interlaboratory studies followed the log-normal distribution. Uncertainty profiles built using the results generally give an expected range for measurement results of 50-200% of reference concentrations for materials that contain at least 1% GMO. This range is consistent with European Network of GM Laboratories and the European Union (EU) Community Reference Laboratory validation criteria and can be used as a fitness for purpose criterion for measurement methods. The effect on the enforcement of EU labeling regulations is that, in general, an individual analytical result needs to be < 0.45% to demonstrate compliance, and > 1.8% to demonstrate noncompliance with a labeling threshold of 0.9%.

    Food intake measurements are essential for many research studies. Here, we provide a detailed description of a novel solution for measuring food intake in mice: the Feeding Experimentation Device (FED). FED is an open-source system that was designed to facilitate flexibility in food intake studies. Due to its compact and battery powered design, FED can be placed within standard home cages or other experimental equipment. Food intake measurements can also be synchronized with other equipment in real-time via FED's transistor-transistor logic (TTL) digital output, or in post-acquisition processing as FED timestamps every event with a real-time clock. When in use, a food pellet sits within FED's food well where it is monitored via an infrared beam. When the pellet is removed by the mouse, FED logs the timestamp onto its internal secure digital (SD) card and dispenses another pellet. FED can run for up to 5 days before it is necessary to charge the battery and refill the pellet hopper, minimizing human interference in data collection. Assembly of FED requires minimal engineering background, and off-the-shelf materials and electronics were prioritized in its construction. We also provide scripts for analysis of food intake and meal patterns. Finally, FED is open-source and all design and construction files are online, to facilitate modifications and improvements by other researchers.
