The authors examined data (N = 34,108) on the differential reliability and validity of facet scales from the NEO Inventories. They evaluated the extent to which (a) psychometric properties of facet scales are generalizable across ages, cultures, and methods of measurement, and, (b) validity criteria are associated with different forms of reliability. Composite estimates of facet scale stability...

BACKGROUND The purpose of this study was to determine the feasibility and reliability of the modified Berg Balance Scale (mBBS) in persons with severe intellectual and visual disabilities (severe multiple disabilities, SMD) assigned Gross Motor Function Classification System (GMFCS) grades I and II. METHOD Thirty-nine participants with SMD and GMFCS grades I and II performed the mBBS twice wi...

Twenty-seven volunteers completed three simulated driving tests to determine test-retest reliability of performance on a low-cost, fixed-base computerized driving simulator. One retest was completed a few hours after the initial drive, and the final retest was completed 7 days following the initial test drive. Driving performance was compared using measures of vehicle control, speed, and reacti...

This study examined 12-month test-retest reliability of the Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) in cocaine-dependent patients. Thirty-one patients completed the SCID-II during the second week of hospitalization for cocaine dependence, and again 12 months later. In both interviews, patients were asked to answer questions about their personality during the ...

Cognitive impairment is common amongst many neurodegenerative movement disorders such as Huntington's disease (HD) and Parkinson's disease (PD) across multiple domains. There are many tasks available to assess different aspects of this dysfunction, however, it is imperative that these show high test-retest reliability if they are to be used to track disease progression or response to treatment ...

BACKGROUND Few assessment instruments have examined the nutrition and physical activity environments in child care, and none are self-administered. Given the emerging focus on child care settings as a target for intervention, a valid and reliable measure of the nutrition and physical activity environment is needed. METHODS To measure inter-rater reliability, 59 child care center directors and...

For DSM-V, simple dimensional measures of disorder severity will accompany diagnostic criteria. The current studies examine convergent validity and test-retest reliability of two potential dimensional indicators of worry severity for generalized anxiety disorder (GAD): percent of the day worried and number of worry domains. In study 1, archival data from diagnostic interviews from a community s...

AIMS Reliabilities of the work environment questionnaire Copenhagen Psychosocial Questionnaire (COPSOQ) have previously been estimated by Cronbach's alpha, but since the internal consistency assumption may not apply to all COPSOQ scales, Cronbach's alpha may underestimate true reliability. This study aims to evaluate reliability in a test-retest design. METHODS We analyzed postal questionnair...

PURPOSE Marras et al. developed a technique to evaluate sincerity of effort during dynamic trunk motion performance. The validity and reliability of the technique have not been evaluated. Therefore, the objective of this study was to first determine whether or not a sincerity of effort measure correctly identified those giving a sincere effort in a blinded randomized control trial and second to...

The aim of this study was to develop and test a questionnaire to measure the research challenges and opportunities faced by dental students. The initial part of the study dealt with designing, developing, and pilot testing of the questionnaire (Dental Students Research Inventory, DSRI), and the later part consisted of field testing. The validity, internal consistency, and test-retest reliabilit...
