Response data containing an excessive number of zeros are referred to as zero-inflated data. When differential item functioning (DIF) detection is of interest, zero-inflation can attenuate DIF effects in the total sample and lead to underdetection of DIF items. The current study presents a DIF detection procedure for response data with excess…

This article presents a new approach to the analysis of how students answer tests and how they allocate resources in terms of time on task and revisiting previously answered questions. Previous research has shown that in high-stakes assessments, most test takers do not end the testing session early, but rather spend all of the time they were…

Longitudinal studies have steadily grown in popularity across the educational and behavioral sciences, particularly with the increased availability of technological devices that allow the easy collection of repeated measures on multiple dimensions of substantive relevance. This article discusses a procedure that can be used to evaluate population…

This article reports a study that investigated the effects of Q-matrix misspecifications on parameter estimates and misclassification rates for the deterministic-input, noisy "and" gate (DINA) model, which is a restricted latent class model for multiple classifications of respondents that can be useful for cognitively motivated diagnostic…

Personality dimensions in the Jesness Inventory among black male delinquents were identified. A principal components factor analysis with a varimax rotation identified three factors: (1) Self-Estrangement, (2) Social Isolation, and (3) Immaturity. The results suggest that the factors might be a part of a larger alienation construct in black…

In the present investigation, the MMPI profile classification program was used to compare the representatives'' of three different sets of diagnostic prototypes. (Author)

Results showed that the failure to find convergent validity for the Smith Test of Sensitivity (TOS) should be considered before employing this instrument for the measurement of sensitivity. Data showed that sensitivity was not meaningfully described as a unified personality trait or the TOS doesn't adequately tap the trait. (Author/DEP)

Results showed that all scales significantly differentiated the samples used, thus demonstrating the validity of the Personal Orientation Dimensions (POD) for discriminating between samples clinically observed to be actualizing or non-actualizing. (Author/DEP)

Reliability and validity data are reported for a questionnaire measure of individual differences in dominance-submissiveness. The 48-item questionnaire, which was balanced for response bias, had high internal consistency and correlated highly with other available measure of dominance. (Author/JKS)

The relationship between Elizur's Hostility Scoring on the Rorschach Test and the Acting-Out Score on the Hand Test was examined. Correlations between the two measures (using several scoring procedures) ranged from .40 to .64. (JKS)

Results show that individuals identified by the personality inventory as extravert or introvert differed significantly in the expected direction on the global self ratings. The results were also obtained for neuroticism. (Author/DEP)

The feasibility of personality measurement through the Semantic Differential and an examination of the degree of relationship between the semantic space and the preference and similarity space derived by independent means are reported. All three phases of the study met with essentially negative results. (Author/NE)

A group peer rating technique was employed to develop reliable measures of sixteen personality traits for adult workers and high school seniors. Several of these traits were found to have high predictive validity for pay differentials, supervisor's ratings, and school grades. (Author/JKS)

Barron's Ego Strength Scale and Rokeach's Dogmatism Scale were administered to a sample of undergraduates in order to assess the relationship between ego strength and dogmatism. A significant inverse relationship was found, as predicted. (JKS)

Examines the validity of the Personal Orientation Dimensions (POD) for measuring changes following an inpatient alcoholic treatment program and describes these changes in terms of concepts of the actualizing person. (Author/DEP)
