When evaluating the utility of a psychological test for clinical decision making, both the psychometric properties of the test (i.e., the reliability and validity of the instrument) and the ambiguity of the language by which test results are interpreted or communicated need to be considered. Although each has been studied independently, to date…

The Forward contains an introduction to the topic of Rasch measurement. Chapters 2, 4, 5, and 7 use a small problem to illustrate the application of Rasch measurement in detail, and methodological issues are considered…

Discusses social impact of IQ used as concrete reference point; promotes a phenomenological approach to psychological development. (ST)

The Rasch model is an item analysis model with logistic item characteristic curves of equal slope, i.e. with constant item discriminating powers. The proposed goodness of fit test is based on a comparison between difficulties estimated from different scoregroups and over-all estimates. (Author)

Paper presents normative data on the Mathematics Anxiety Rating Scale (MARS), which measures anxiety associated with number manipulation or mathematics concepts. (Authors)

An average of the two scores on the LIPS and PPVT provides an estimate of current IQ comparable to that which might be obtained by a WISC or S-B. (Authors/MB)

Article examines the effects of nonreinforced trials during presolution of a concept identification task. (Author/ML)

Estimates of the validity of random short forms can serve as benchmarks against which to appraise the validity of particular short forms. Formulas are presented for estimating the validity of random short forms and illustrated with Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Minnesota Multiphasic Personality Inventory data. (Author/CM)

Cognitive component research on aptitudes has shown that performance on test items depends on a series of processing events. Each processing component potentially defines a separate construct that contributes to item and subject differences in performance. This article presents the multicomponent latent trait model for measuring these component…

Examined the hypothesis that deficits in interpersonal and problem-solving skills are significantly related to nonclinical depression. A behavioral role-playing measure of competence in male college students--the Problem Inventory for College Students--was developed and tested. Results provided partial support for the hypothesized relationship…
