Learning objects are interactive web-based tools that support the learning of specific concepts by enhancing, amplifying, and/or guiding the cognitive processes of learners. Research on the impact, effectiveness, and usefulness of learning objects is limited, partially because comprehensive, theoretically based, reliable, and valid evaluation…

The present study tested the predictive validity of "Making Better Career Decisions" ("MBCD"), a computer-assisted career decision-making system. Seventy clients who had used "MBCD" six years earlier were interviewed by telephone about their present field of study or occupation and the degree of their satisfaction with their occupational choice.…

The current study gathered internal structural validity and external criterion validity evidence for the Experiences in Close Relationships-Revised Questionnaire (ECR-R) scores. Specifically, confirmatory factor analysis of the data provided general support for the hypothesized two-factor model, and hypothesized relationships with external…

THE MINNEAPOLIS REHABILITATION CENTER (MRC) STUDIED MINNESOTA MULTIPHASIC PERSONALITY INVENTORY (MMPI) SCORES TO SEE IF THEY RELIABLY PREDICTED EMPLOYMENT OUTCOME AND TREATMENT EFFECTS. IT WAS DEEMED IMPORTANT FOR AGENCIES TO HAVE A METHOD OF DIAGNOSING PROBABLE RETURN-TO-WORK CLIENTS BEFORE SELECTING THOSE FOR REHABILITATION. A METHOD OF…

The current criterion for prediction of performance of student naval aviators is the dichotomy of success versus failure in undergraduate flight training. This criterion has enabled the naval air training command to make reasonable estimates of the probability of an applicant or student completing flight training. However, a costly attrition…

An index that reflects the accuracy of selection associated with a predictive validity of "r" is presented. Based on Sheppard's thoerem on median dichotomies, it is a measure of improvement over chance assignment to "accept" (or "reject"). Because the index is a measure of the accuracy of this assignment, rather than…

An empirical comparison of three proposed indices of predictor variable potency is presented. These indices are: (1) the scaled weights of the first Fisher-type discriminant function, (2) the total group estimates of the correlations between each predictor variable and the first Fisher-type function, and (3) the within-groups estimates of the…

Conceptualizes dynamic criteria as changes in group average performance over time, changes in validity over time, and changes in rank-ordering of scores on the criterion over time. Analyzes and submits to tests each concept of dynamic criteria. Concludes that dynamic criteria have been overemphasized and are rare phenomena. (BH)

Employed the Child Abuse Potential Inventory to evaluate abuse potential in a group of parents (N=200) at risk for problems in parenting. Results showed a significant relationship between Inventory abuse scores and subsequent abuse, and between abuse scores and later neglect. (LLL)

When selection occurs on the basis of two or more predictors, multivariate restriction of range can reduce various parameters of a validation study. A Statistical Analysis System (SAS) and a Fortran IV program are described that allow for correction of criterion standard deviation(s) and zero-order validities. (Author)

The problems which can arise in predicting the presence or absence of statistical interactions when a theoretical model is not set into correspondence with the experimental design model are considered in the context of a specific study of developmental differences in distractibility. (Author/HS)

A high correlation between predicted and criterion values in cross-validation may not always be a sufficient indicator of goodness of prediction. An alternative indicator of goodness of prediction is reviewed in terms of what kind of prediction is sought. (Author)
