Evaluations of the risk of recurrent violence were conducted for 162 Canadian mentally disordered criminal defendants through the assembly of actuarial data, scores from special-to-purpose psychometric instruments, and scaled global predictions of dangerousness to others. Professional clinicians were not more accurate than nonclinical raters. (JPS)

Analysis of predictor variables (intelligence, Sims SCI Occupational Rating Scale, and Family Wage Earners' Occupational Level) used singly or in any combination showed relationship to stated occupational preference beyond 0.001 level of significance. Counseling implications discussed. (Author/CJ)

Describes two invariance tests, the jackknife procedure and Procrustean rotation, and applies them in a discriminant analysis for this heuristic study. Invariance testing helps to prevent overemphasis on findings of statistical significance and overgeneralization of a research result, and thus is gaining favor as an indicator of result importance.…

A study examined the predictive validity of two methods of prior knowledge assessment: free association and prediction. Subjects, 72 sixth graders from suburban public and private schools, were divided into four groups: standard free association; standard free association plus prediction; definitional free association; and definitional free…

By securing a network of variables related to cognitive outcomes, we may emphasize important behaviors that are adjuncts to learning and mitigate measurement problems of the performance contract. (Author)

A method for incorporating decline over time of the predictive validity of scores into mental test theory is presented. The procedure utilizes concepts from multiple regression and analysis of repeated measures. (JKS)

The correction for attenuation formulas for partial, multiple, and canonical correlation coefficients are discussed and the effects of measurement errors on these statistics are explored. The notation is standardized and the derivation extended where appropriate. It is shown that as the reliabilities of the predictors become more disparate, the…

This paper evaluates the effects of two distinct modes of feedback to students. These two modes comprise: (1) predicted final course grade, and (2) current standing in class. The experiment was conducted with a final year class of 56 students attending a required half-year course in Educational Measurement. The class was divided into four…

Conducted a Monte Carlo computer simulation of the ANOVA design to detect job differences. The design proved reasonably powerful in detecting differences. A second study used Monte Carlo methods to analyze the viability of techniques for determining job differences. Offers guidelines for selecting statistical techniques. (Author/RC)

Determination of the fairness of preschool tests for use with children of varying cultural backgrounds is the major objective of this study. The predictive validity of a battery of preschool tests, chosen to represent the core areas of preschool assessment, across race and sex, was evaluated. Validity of the battery was examined over a 12-month…

When a number of school readiness tests were used with a group of 322 kindergarten children to predict end of first-grade Metropolitan Achievement Test scores, no evidence of racial bias and only minimal effects of sex bias were found in the predictions based on analysis of variance. (CTM)
