This study tested five confirmatory factor analytic (CFA) models of the Positive Affect Negative Affect Schedule (PANAS) to provide validity evidence based on its internal structure. A sample of 223 club sport athletes indicated their emotions during the past week. Results revealed that an orthogonal two-factor CFA model, specifying error…

An efficient algorithm for maximizing split-half reliability coefficients is described. Coefficients derived by the algorithm were found to be generally larger than odd-even split-half coefficients or other internal consistency measures and nearly as large as the largest split half coefficients. MSPLIT, Odd-Even, and Kuder-Richardson-20…

A computer program is described which provides comprehensive information on test profile differences among independent groups based upon profile centroid separation, shape, elevation, and scatter. Descriptive statistics, univariate and multivariate measures of strength of association, test of homogeneity of covariance matrices, and comparative…

It was predicted that there would be variable IQ discrepancies at different ages because of differential age adjustments on the norms of the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised (WAIS-R). The use of equivalent WAIS and WAIS-R sums of scaled scores demonstrated the predicted variable discrepancies. (Author/BW)

The diagnostic accuracy of nonadjusted and bootstrapped diagnosis was compared using a sample of 1,455 psychiatric patients who completed the Millon Clinical Multiaxial Inventory. The usefulness of bootstrapping depended on the criteria for accuracy. Conditions under which bootstrapping might increase diagnostic accuracy are detailed. (SLD)

Six methods of scoring multiple true-false items were compared in terms of reliabilities, difficulties, and discrimination. Results suggest that, for norm-referenced score interpretations, there is insufficient evidence to support any one of the methods as superior. For criterion-referenced score interpretations, effects of scoring method must be…

Ability estimates obtained from applying finite state score theory, item response models, and classical test theory to score multiple-choice items were compared using responses of 1,230 examinees. Scoring models provided essentially the same ranking of examinees, but ease of use and interpretation support the use of the classical test model. (SLD)
