The purpose was to investigate the test-retest reliability of the 50-Foot Timed Walk (50FWT), and 30-Second Chair Stand Test (30CST) in the patients with total hip arthroplasty (THA). The study was a test-retest study. Thirty-seven patients with THA performed two trials for both the 30CTS and 50FWT on the same day with one hour interval. To assess reliability, the intra-class correlation coeffi...

OBJECTIVE This report examined limitations in our ability to assess clinically significant change (CSC) in randomized controlled trials of treatments of self-reported pediatric chronic pain intensity. METHODS The following were reviewed: (a) approaches to assessing CSC; (b) approaches to assessing CSC used in psychological treatment studies of self-reported pediatric chronic pain intensity in...

BACKGROUND The objective was to determine the test-retest reliability and criterion validity of the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD). METHODS Forty-five non-wheelchair dependent subjects were recruited from three Dutch rehabilitation centers. Subjects' diagnoses were: stroke, spinal cord injury, whiplash, and neurological-, orthopedic- or back disord...

Methods The tool was subjected to translation and re-translation, and the test-retest reliability of a proposed version for use in Brazil was analyzed. Results Of the 548 questionnaire respondents, a convenience sample of 68 informants ...

PURPOSE The aims of this study were (1) to develop centile reference values for anaerobic performance of Dutch children tested using the Muscle Power Sprint Test (MPST) and (2) to examine the test-retest reliability of the MPST. METHODS Children who were developing typically (178 boys and 201 girls) and aged 6 to 12 years (mean = 8.9 years) were recruited. The MPST was administered to 379 chi...

OBJECTIVE. To develop an instrument (Scale for Positive Aspects of Caregiving Experience [SPACE]) that evaluates positive caregiving experience and assess its psychometric properties. METHODS. Available scales which assess some aspects of positive caregiving experience were reviewed and a 50-item questionnaire with a 5-point rating was constructed. In all, 203 primary caregivers of patients wit...

Objective: This article reports findings of three studies addressing convergent validity and test-retest reliability of the Youth Rating Scale of the Behavioral and Emotional Rating Scale–Second Edition (BERS-2). Method: Pearson product–moment correlations were used in all three studies, the first two addressing convergent validity and the third addressing test-retest reliability. Results: Anal...

Retest reliability is a better predictor of validity than is internal consistency. One explanation for this is item-specific variance, which distinguishes different nuances of a facet and contributes to retest reliability but not internal consistency. Specific variance at the facet level is temporally stable, consensually validated, and heritable; a consideration of the role of specific varianc...

This study was aimed to investigate the test-retest reliability and validity of a short version of the New Brief Job Stress Questionnaire (New BJSQ) whose scales have one item selected from a standard version. Based on the results from an anonymous web-based questionnaire of occupational health staffs and personnel/labor staffs, we selected higher-priority scales from the standard version. Afte...
