Developed an Italian version of the Self-Description Questionnaire (SDQ-III) and studied the reliability and factorial validity of this translated instrument. Results show that the translated version has psychometric properties similar to those of the original English version. (SLD)

A series of studies refined 17 scales of the Expanded Skills Confidence Inventory (n=934) and validated it with an adult sample (n=972). Scales were internally consistent, showed predictable patterns of gender differences, and were highly related to predicted Holland confidence themes. Discriminant analyses across 8 largest occupational groups…

Vietnam combat veterans who had posttraumatic stress disorder (PTSD, N=25), were anxious (N=7), or were healthy (N=18) completed psychometric test battery. PTSD subjects differed significantly from healthy subjects on almost all measures but showed fewer differences from anxious subjects. Typical PTSD subject was characterized as anxious,…

Issues arising from difference scores with zero reliability that nevertheless allow a powerful test of change are discussed. Issues include the appropriateness of underlying statistical models for psychological data and the relationship between difference scores and power. Increases in reliability always increase power for a fixed effect size.…

A theory of timing is proposed, based on the observation that signals of reinforcement elicit adjunctive behaviors. Transitions between these behaviors are described as a Poisson process. These behaviors may come to serve as the basis for conditional discriminations of the passage of time. (SLD)

The frequencies of "m" independent "p-way" contingency tables are analyzed by a model that assumes that the ordinal category data in each of "m" groups are generated from a latent continuous multivariate normal distribution. The model permits analysis of several groups of individuals simultaneously. (TJH)

Within covariance structural analysis, a unified approach to asymptotic theory of alternative test criteria for testing parametric restrictions is provided. More general statistics for addressing the case where the discrepancy function is not asymptotically optimal, and issues concerning power analysis and the asymptotic theory of testing-related…

Covariance structure modeling was applied to the study of psychometric "g" in relation to collegiate academic performance and socioeconomic status. Results with 339 college students showed that psychometric "g" accounted for a substantial proportion of the variance in academic performance. (SLD)

Developed Measure of Moral Orientation, objective instrument that measured moral orientation of college students. Administered instrument and conducted analyses to determine its psychometric properties. Results of pilot (n=64) and field (n=366) testing with college students suggest that the Measure of Moral Orientation is psychometrically sound…

Presents preliminary psychometric data for two inventories that assess conflict in couples. Discusses factor structure of items, internal consistency and one-year stability of composite scores, relationship between couple members' composite scores, and link between composite scores and relationship satisfaction, change in satisfaction, and…

Vertex event-related potentials (ERPs) were obtained from undergraduates performing an inspection time task together with measures of inspection time (n=35) and mental ability (n=28). Techniques that reveal changes over time in the relationship between ERP measures and psychometric indices were presented. (SLD)

A flexible data analysis approach is proposed that combines the psychometric procedures seriation and multidimensional scaling. The method, which is particularly appropriate for analysis of proximities containing temporal information, is illustrated using a matrix of cocitations in publications by 18 presidents of the Psychometric Society.…

Notes that, although consultation researchers and practitioners have called attention to need for more psychometrically sound instruments, little advancement has occurred in this area. Outlines key quantitative and qualitative psychometric standards for organizational consultation assessment and evaluation instruments. Presents framework and…

A nonspatial operationalization of the Krumhansl distance-density model of similarity is presented. The conceptual model and empirical evidence are reviewed. A nonspatial, tree-fitting methodology is described, which is sufficiently flexible to fit several competing hypotheses of similarity formation. Extensions to spatial models, three-way…

An approach is presented for determining unidimensional scale estimates that are relatively insensitive to limited inconsistencies in paired comparisons data. The solution procedure--a minimum-cost network-flow problem--is presented in conjunction with a sensitivity diagnostic that assesses the influence of a single pairwise comparison on…
