In this study, we describe what factors influence the observed score correlation between an (external) anchor test and a total test. We show that the anchor to full-test observed score correlation is based on two components: the true score correlation between the anchor and total test, and the reliability of the anchor test. Findings using an…

In the current article, we describe the development and validation of the Mistake Rumination Scale as a supplement to existing trait and cognitive measures of perfectionism. The Mistake Rumination Scale is a seven-item inventory that taps the tendency to ruminate about a past personal mistake. Psychometric analyses confirmed that the Mistake…

An aptitude test requiring 10-minutes' administration time was administered to high school students learning Forkner, Century 21, and Gregg shorthand for the purpose of determining test validity for different shorthand systems. Validity data were obtained from approximately 2000 students. Aptitude test reliability ranged from KR20=0.88 to 0.90.…

The predictive power of the Split-Half version of the Wechsler Intelligence Scale for Children--Revised (WISC-R) Object Assembly (OA) subtest was compared to that of the full administration of the OA subtest. A cohort of 218 male and 49 female adolescent offenders detained in a Texas juvenile detention facility between 1990 and 1992 was used. The…

Data from 6,472 South Carolina residents aged over 55 years support the reliability of S. Katz's Activities of Daily Living scale when data are collected by self-report telephone interview. Results indicate that telephone interview methods are a fast, inexpensive, and safe way to collect data for research and policy formation. (SLD)

Interset and set-to-total correlations for the California Card Sorting Test were studied for 135 college students and 63 elementary school students. Although subsets were not equivalent, the generally good correlations between subset and total test scores indicated that use of the individual subsets as short forms is justified. (SLD)

Credentialing agencies that use multi-test examinations (MTEs) should be concerned with the quality of pass/fail outcomes as well as with the proportion of candidates passing. This study addressed three questions: (1) the effects on passing rate of MTE reliability, number of tests comprising a MTE, and correlations between pairs of component…

Research is reported on four tests commonly used in South Africa to select apprentices, the Intermediate Mental Alertness Test, the High Level Figure Classification Test, the Blox Test, and the Mechanical Comprehension Test. Samples were as follows: (1) 206 Asian, 208 Black, 102 Coloured, and 99 White mostly male applicants for sugar industry…
