Surveys 354 nationally certified school psychologists on the perceived usefulness of the Wechsler Intelligence Scale for Children-III (WISC-III) in general and profile analysis in particular. Practitioners rated the WISC-III as very useful for determining diagnosis and educational placement, but less useful for developing instructional strategies…

Surveyed AERA members regarding their perceptions of: statistical issues and statistical significance testing; the general linear model; stepwise methods; score reliability; type I and II errors; sample size; statistical probabilities as exclusive measures of effect size; p values as direct measures of result value; and p values evaluating…

Analyzed the assessments of 53 portfolios used to evaluate participants in a development course for higher education teachers at the United Kingdom's Open University. Findings included a high reliability in assessment at the level of course outcomes, and that cumulation of component assessments is very likely to reduce the reliability of overall…

In this study, self-reports of 34 individuals with developmental disabilities (DD) were compared with proxy ratings from family and providers. Correlations between the ratings of individuals with DD and the proxy raters were low, as were the correlations between family members and providers. In all scales except "cognition," the individual with DD…

Assessed the psychometric properties of the Physical Activity and Disability Survey (PADS), which measures physical activity for people with disabilities and chronic health conditions. Cross-sectional and pre-post designs were employed with 103 people who had disabilities and chronic health conditions. Results supported the PADS' reliability and…

Evaluates the reliability and validity of a new self-report measure of Self-Understanding of Interpersonal Patterns (SUIP). Measure demonstrates good internal consistency, test-retest reliability, and discriminant validity. The SUIP further demonstrates convergent validity with measures of analytical and self-improving personality traits in a…

Analyzes a learning disabilities (LD) questionnaire administered to 150 adults including college and university students, and adults referred to a psychoeducational clinic for assessment or treatment related to LD. Finds that the LD screening test had internal consistency and good test-retest reliability, as well as criterion validity. Finds…

Evaluated the validity and reliability of a medicine ball throw test to evaluate explosive power. Data on competitive sand volleyball players who performed a medicine ball throw and a standard countermovement jump indicated that the medicine ball throw test was a valid and reliable way to assess explosive power for an analogous total-body movement…

The Career Decision-Making Difficulties Questionnaire was completed in a Hebrew paper version (n=417) and Internet version (n=837), showing similar internal consistency and reliability in both versions. Response pattern of 24% of Internet users was questionable. Comparison of results from English paper (n=403) and Internet (n=182) versions found…

Undergraduate students (N = 150) participated in a study developing a 10-item scale (the Noctcaelador Inventory; NI) to measure noctcaelador: adoration and attachment to the night-sky. The NI demonstrated good internal consistency, test-retest reliability, normality, and preliminary validity. The scale significantly correlated with self-reported…

This investigation was conducted to validate the Beck Depression Inventory--II (BDI-II; A. T. Beck, R. A. Steer, & G. K. Brown, 1996) in samples of adolescent psychiatric inpatients. The sample in each substudy was primarily Caucasian. In Study 1, expert raters (N=7) and adolescent psychiatric inpatients (N=13) evaluated the BDI-II items to assess…

The authors evaluate Angrist and Krueger (1991) and Bound, Jaeger, and Baker (1995) by constructing reliable confidence regions around the 2SLS and LIML estimators for returns-to-schooling regardless of the quality of the instruments. The results indicate that the returns-to-schooling were between 8 and 25 percent in 1970 and between 4 and 14…

Tests are a natural part of education, from the quizzes, essays, and classroom tests that teachers have traditionally administered to the high-stakes tests that states use to make decisions about graduation, promotion, and school funding and governance. In this article, the author stresses the need to learn the unintended consequences of…

Two new prophecy formulas for estimating item response theory (IRT)-based reliability of a shortened or lengthened test are proposed. Some of the relationships between the two formulas, one of which is identical to the well-known Spearman-Brown prophecy formula, are examined and illustrated. The major assumptions underlying these formulas are…

The Center for Epidemiologic Studies-Depression (CES-D) Scale is among the most commonly used measures of depressive symptomatology. Despite this, a paucity of research has been undertaken to examine the psychometric properties of responses to this scale. This meta-analytic study examined previously published studies of caregiving to identify…
