Administered the Wechsler Intelligence Scale for Children, Wechsler Intelligence Scale for Children-Revised, and Wechsler Preschool Primary Scale of Intelligence in a counterbalanced design to randomly selected elementary school children (N=72). Results indicated that the verbal Intelligence Quotients (IQs) were comparable, but the performance and…

Samples in research on individual and group differences may be selected based on whole scores which differ from the population mean. Children are diagnosed in clinical practice with a whole score. These procedures produce regression to the population mean which can affect accuracy and adequacy of part score interpretations. (Author/DWH)

The article reviews Consumer's Guide to Tests in Print, noting its purposes (to provide objective information about technical characteristics of standardized tests); criteria for evaluating standardizaton, reliability, and validity; and its rating system based on evaluations of selected review panel members.

Carried out four experiments in which male and female undergraduates (N=384) completed the Beck Depression Inventory under conditions ranging from absolute anonymity to a face-to-face interview. Results showed no evidence that depression is more severe or common in females. Responses appeared essentially unaffected by method of administration.…

Information was gathered from college students to observe choice of postcoital contraception (PCC) and the effectiveness of the choice. Results indicate that PCC is an effective second chance to prevent unintended pregnancy. Research methodology is presented. (Author/DF)

Addresses the issues of whether test scores are affected by the prior availability of the items on a test. Concludes that, while disclosing items significantly affects test scores, the magnitude of the disclosure effect drecreases with an increase in the size of the disclosed pool. (EKN)

The problem of determining which of several populations has the largest mean is considered. The procedure described by Dudewicz and Dalal is extended to the case of unequal sample sizes. (JKS)

Concludes that The London Procedure does not reflect contemporary research in the fields of literacy acquisition and learning disabilities. (AEA)

The Locus of Control Inventory for the Deaf (LCID), consisting of a 23-item Likert-like scale, and two commonly used scales to assess locus of control in hearing persons were administered to 174 deaf freshman students. Intercorrelation findings demonstrated greater soundness of the LCID as compared with the other scales. (Author)

This article illustrates the use of generalizability theory in special education to estimate the reliability of a measure when there is more than one source of error in the universe of inference and how the effects from changing the number of items and/or raters can be evaluated. (Author)

Impression marking of English Language essay and summary questions by pairs of examiners is shown, as expected, to be more reliable than single marking. Given the limited statistical information available, it is concluded that pairing of examiners can as well be done by random or quasi-random means as by attempts at calculated matching. (Editor/RK)

A procedure designed to help instructional decision-makers evaluate individual sources of diagnostic information in terms of their functional utility may add a desirable measure of precision to their instructional prescriptions for learners. (Author)

Recently, an evaluation procedure, behaviorally anchored rating scales (BARS), has been developed that attempts to capture performance in multidimensional, behavior-specific terms. Article reviews and evaluates the research on BARS and suggests new directions for future research. (Author/RK)

Two IRT-based procedures to estimate test reliability for a certification exam that used both adaptive (via a MST model) and non-adaptive design were considered in this study. Both procedures rely on calibrated item parameters to estimate error variance. In terms of score variance, one procedure (Method 1) uses the empirical ability distribution…
