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…

This investigation was conducted to estimate the reliability and validity of scores on the Riso-Hudson Enneagram Type Indicator (D. R. Riso & R. Hudson, 1999a). Results of 287 participants were analyzed. Alpha suggests an adequate degree of internal consistency. Evidence provides mixed support for construct validity using correlational and…

The Hartnett, Nelson, and Rinn 2004 study indicates that diagnostic confusion between ADD/ADHD and giftedness exists, and that research on medication practices is warranted. Mika disagrees, saying that there is no empirical evidence of misdiagnosis of gifted children as having ADD/ADHD. We disagree with Mika's logic, and describe evidence that…

The goal of this study was to test the internal reliability of a Spanish translation of the CDI, (i.e., CDI-LA), a potentially useful screening instrument for Hispanic youngsters in their native language at a primary-care level. Self-reported symptoms of depression were assessed with the CDI-LA in a school sample of 205 Hispanic students. Girls…

The stability of scores on the Peer-Relations subscale of the Self-Esteem Questionnaire (SEQ) was examined over 11 to 13 months, longer than in previous research. Participants were 839 mainstream Scottish pupils aged 8 to 14 years old (48% male), allowing for the psychometric qualities of the scale to be assessed in a younger sample than…

The Kuder Career Search with Person-Match (KCS) has a variety of applications; however, the KCS is best suited to help an individual in generating a list of reasonable occupational possibilities. The KCS includes a radical innovation in interest measurement because individuals are not compared to a group within an occupation but are compared to…

This article studies the ordinal reliability of (total) test scores. This study is based on a classical-type linear model of observed score (X), true score (T), and random error (E). Based on the idea of Kendall's tau-a coefficient, a measure of ordinal reliability for small-examinee populations is developed. This measure is extended to large…

This article reviews the Early Reading Diagnostic Assessment second edition (ERDA-2). The Early Reading Diagnostic Assessment, second edition (ERDA-2; The Psychological Corporation, 2003) assesses the acquisition of reading skills in children from kindergarten to Grade 3. The ERDA-2 is a collection of subtests adapted primarily from the Wechsler…
