Responses of 36 bilingual adults, 107 Puerto Ricans, and 247 Puerto Rican adolescents demonstrate the high degree of measurement equivalence between Spanish and English versions of the Psychological Acculturation Scale, developed to assess acculturation from a phenomenological perspective. (SLD)

This study empirically examined the behaviors of item and person statistics derived from item response theory and classical test theory, focusing on item and person statistics and using a large-scale statewide assessment. Findings show that the person and item statistics from the two measurement frameworks are quite comparable. (SLD)

First-year college students (n=506) completed Raven's Advanced Progressive Matrices (J. Raven, J. Court, and J. Raven, 1988). Data were used to contribute to the normative database for American college students. A short form developed from 12 items of the original 36 was found to possess acceptable psychometric properties. (SLD)

The relative difficulty of seven test wiseness skills was studied with 243 undergraduates, who completed a measure of such skills. The use of specific determiners as a cue was significantly more challenging than eliminating irrelevant alternatives, selecting the alternative with the most information, or using grammar cues. (SLD)

Comparison of six procedures to test for location equality among two or more groups when population variances are heterogeneous suggests that, when the variance homogeneity and normality assumptions are not satisfied, and the design is unbalanced, the use of any of these test statistics with the usual least squares estimators is not recommended.…

The normality of number distributions generated by various random-number generators were studied, focusing on when the random-number generator reached a normal distribution and at what sample size. Findings suggest the steps that should be followed when using a random-number generator in a Monte Carlo simulation. (SLD)

First- and second-order confirmatory factor analyses were conducted to evaluate the factorial validity of scores on two positive affect (PA) measurement instruments and a multidimensional representation of PA using a sample of 232 undergraduates. Both measures were well represented by multifactorial models, and each was represented well by a…

Whether the measurement of intelligence by the Wechsler Intelligence Scale for Children III (WISC-III) differs for children who exhibit inappropriate test-taking behavior was studied empirically with 247 inappropriate behavior and 515 appropriate behavior children. Results suggest that the factor index and full-scale IQ may have different meanings…

The psychometric properties of the Learning and Study Strategies Inventory-High School (LASSI-HS) was studied with 139 female high school students from Singapore. Results indicate that the LASSI-HS yields reliable measures of learning and study behaviors, but the underlying structure of the measure suggested in its manual was not supported. (SLD)

The purpose of this study was to obtain validity and reliability indexes for scores on a 12-item scale measuring family perspectives on extended school year (ESY) programs for students in special education. Responses from 128 families with a child potentially eligible for ESY programs indicated that a two-component model was both valid and…

Individual differences in responsibility may be observed in a doctoral candidate's assumption of responsibility for completing the doctoral dissertation. Responses to the Responsibility Scale by 142 doctoral graduates and 97 nongraduates (all but dissertation) show that two factors underlie responses to the scale. Appendix contains the…

Monte Carlo studies were conducted to compare four multivariate analysis of variance (MANOVA) simultaneous test procedures (STPs) in terms of power and Type I error under various conditions including violations of MANOVA assumptions. Results do not support the hypothesis that the moderately restricted STP is a good compromise between…

The degree to which scale distortion in the ordinary difference score can be removed by using differences based on estimated examinee proficiency (theta) in either conventional or adaptive testing situations was studied using Item Response Theory. Using estimated thetas removed much scale distortion for both conventional and adaptive tests. (SLD)

Whether traditional Likert-type focus of attention at work scales would outperform the one-item scales developed by D. Gardner and others (1989) was studied with responses of 492 automobile-services-club employees. Confirmatory factor analysis did not show either method to be better empirically. Situations in which the one-item scale might be…

Responses of 903 Canadian college students to the Self-Monitoring Scale (M. Snyder, 1974) and artificial data are used to illustrate the importance of pairing test theoretical structure with quantitative characteristics, including conditional association (CA) and strong positive orthant dependence (SPOD). Tests for CA and SPOD are reviewed. (SLD)
