Examined stability and behavioral correlates of peer acceptance from kindergarten through second grade. Found that social acceptance and peer competence were relatively stable. Stably rejected children showed poorer peer and teacher ratings of social behavior than others; transiently rejected children were rated moderate in social skill. Changes…

This research report describes the reliability and validity of hand-held dynamometer measurements of knee extension force obtained from 13 patients referred for physical therapy. Results found that hand-held dynamometry can be used to obtain reliable measures of muscle strength; however, correlation between strength measures and function was not…

This overview of the role of error and tolerance for error in measurement asserts that the generic precision associated with a measurement procedure is defined as the root mean square error, or standard error, in some relevant population. This view of precision is explored in several applications of measurement. (SLD)

Used latent means analysis in the framework of structural equation modeling to explore the factor structure and gender differences associated with the Personal Style Inventory (PSI; C. Robins and others, 1994) with 508 Korean undergraduates. Results support the cross-cultural stability of the PSI factor structure. Women had higher scores than men…

Conducted a reliability generalization meta-analysis of subscale and total scale scores on the Web-administered LibQUAL+ (tm) (Cook and others, 2002), a measure of library service quality. Data for 18,161 participants from 43 universities show that score reliabilities are remarkably invariant across campuses and different over groups. (SLD)

Examines the validity and reliability of a questionnaire developed to determine if college students in the America Reads Challenge who tutored elementary school children reported attitude changes. Finds significant positive attitude changes along the four dimensions of the questionnaire: attitude toward self, children, tutoring, and others. Notes…

This study supported evidence of reliability and validity of the Theoretical Orientation Profile Scale-Revised (TOPS-R) scores. The TOPS-R was designed to measure theoretical orientation among counselors and trainees. Factor analysis yielded a 6-factor solution accounting for 87.5% of the total variance in the scale. The 6 factors corresponded to…

Eight subtests were selected from the Wechsler Intelligence Scale for Children--Third Edition (WISC-III) to make a short form for clinical use. Results with the 2,200 children from the WISC-III standardization sample indicated the adequate reliability and validity of the short form for clinical use. (SLD)

Describes the development and validation of a measure of the stress experienced by African Americans as a result of daily encounters with racism and discrimination. The scale has adequate indexes of internal consistency and fair-to-adequate estimates of test-retest stability. Several other factors also indicated the measure's reliability. (RJM)

Summarizes a United Kingdom study investigating differential school effectiveness. Measures overall school effects versus departmental differences in effects on 16-year-old students' General Certificate in Secondary Education performance, the internal consistency of departmental effects across six subject outcomes, and the stability of school and…

Calculated year-1 to year-2 stability of assessment data from 21 states and 2 Canadian provinces. The median stability coefficient was 0.78 in mathematics and reading, and lower in writing. A stability coefficient of 0.80 is recommended as the standard for large-scale assessments of student performance. (SLD)

Derived general formulas to determine the sample size requirements for hypothesis testing with desired power and interval estimation with desired precision. Illustrated the approach with the example of a screening test for adolescent attention deficit disorder. (SLD)

Provides a critical and comparative evaluation of the five most commonly used published rating scales for the assessment of ADHD. Reviews were conducted in four main areas: content and use, standardization sample and norms, scores and interpretation, and psychometric properties. Scales with the strongest standardization samples and evidence for…

The estimation accuracy of procedures based on classical test score theory and item response theory (generalized partial credit model) were compared for examinations consisting of multiple-choice and extended-response items. Analysis of British Columbia Scholarship Examination results found an error rate of about 10 percent for both methods, with…

Studied descriptive measurement reliability and validity of scores from the newly developed Mathematics Self-Efficacy Scale (MSES) for class and test with a sample of 302 Australian high school students. Results provide some evidence for the psychometric properties of the MSES in both contexts, but there is evidence of failure to counterbalance…
