Used confirmatory methodology to examine reliability and validity of Family Adaptability and Cohesion Evaluation Scales-III in 922 families with children with disabilities. The Cohesion Scale proposed by instrument authors remained intact. The original Adaptability Scale was divided into two scales, Adaptability focusing on leadership and family…

Argues that "goodwill," the third of Aristotle's three elements of ethos, is ignored by many contemporary researchers because of misanalysis and/or misinterpretation of data. Reports empirical research indicating the existence of the goodwill dimension as part of the structure of the ethos/source credibility construct, and provides a…

Describes a short-form assessment scale for drug involvement, providing information about its administration, scoring, and interpretation. Discusses the initial research conducted to validate the instrument and provides reliability data. Also details the development of a clinical cutting score that will help practitioners evaluate the significance…

Summarizes the benefits of computerized assessment and provides a review of some practical issues concerning measurement, item and examinee characteristics, hardware, and software. Adequate measures of reliability and validity have been established for many computer-based tests, and the benefits of computer testing have been realized in applied…

Assessment of visual acuity, using Teller Acuity Cards, was combined with observations of behavioral state to indicate central nervous system activation in 24 individuals with mental retardation. Results indicate that forced-choice preferential-looking technique can be used to test visual acuity in this population unless the participant is drowsy.…

One hundred middle school students completed four measures of mathematics skills (involving basic facts and estimation) twice in one week. Criterion measures included school grades, standardized test scores, and teacher ratings. Correlation and regression analyses indicated the measures are reliable and possess acceptable levels of criterion…

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…
