Argues that data on siblings provide a way to account for the impact of unmeasured, omitted variables on relationships of interest because families form a sort of natural experiment, with similar experiences and common genetic heritage. Proposes a latent-variable structural equation approach to the problem, which provides estimates of both within-…

This study investigated the psychometric characteristics of the Family Empowerment Scale (FES) with 228 families having children with severe emotional disturbance or attention deficit/hyperactivity disorder. Factor analyses provided a four-factor solution (systems advocacy, knowledge, competence, and self-efficacy) and supported the use of the…

It is shown that goodness-of-fit criteria developed for the evaluation of multivariate structural models can be applied to assist in evaluating the dimensionality of a test consisting of binary items, and correlative methods regularly used in factor analysis can be employed to diagnose causes of misfit.

The dynamic factor model proposed by P. C. Molenaar (1985) is exhibited, and a dynamic nonstationary factor model (DNFM) is constructed with latent factor series that have time-varying mean functions. The use of a DNFM is illustrated using data from a television viewing habits study. (SLD)

First- and second-round commentaries on an article by L. Guttman are presented. The following authors responded, with two articles each: (1) E. E. Roskam and J. Ellis; (2) P. H. Schonemann; (3) A. R. Jensen; (4) J. C. Loehlin; and (5) J.-E. Gustafsson. (SLD)

Conducted principal components analysis of Counselor Reaction Form (CRF) on large number of actual counseling clients. Findings from 5 psychologists and 7 practicum students who had seen 280 college student clients revealed 3 scales using novice trainees and 3 scales using psychologists. Found differences between experienced psychologists and…

A hierarchical factor analysis of the intercorrelations among the Revised California Psychological Inventory (CPI-R) folk scales shows a strong general profile elevation factor for both men and women, which is noteworthy because it provides an empirical basis for interpreting the CPI-R as a measure of personal adjustment. (SLD)

Investigates the validity of the Reading Anxiety Scale. Finds that (1) reading anxiety shows a stronger negative correlation with reading achievement than does general anxiety; and (2) although general anxiety and reading anxiety correlate substantially, reading anxiety measures something beyond general anxiety. (RS)

Sufficient conditions are derived for the consistency and asymptotic normality of the least squares estimator of a trilinear decomposition model for multiway data analysis. The limiting covariance matrix is computed. (Author/SLD)

Effects of different weighting schemes on selecting the optimal number of observations in multivariate-multifacet generalizability designs are studied when cost constraints are imposed. Comparison of four schemes through simulation indicates that all four produce similar optimal values and that reliability should be similar. (SLD)

Personality profiles of industrial scientists, musicians and artists, and general undergraduates (total n=99) showed no difference between scientific and artistic groups on the Creativity composite index. Self-reports of involvement in creative behavior, collected from 590 individuals, revealed that creative people tend to cross-train and to…

The latent structure of the Self-Monitoring Scale of M. Snyder (1974) is evaluated by comparing several measurement models suggested by previous factor analysis of the scale using sample data from 1,113 college students. Implications of results are discussed in relation to self-monitoring and the use of factor analysis. (SLD)

The Chinese revision of the Wechsler Adult Intelligence Scale was factor analyzed for 55 Chinese subjects with mental retardation. Results indicated a two-factor solution comprising Verbal Comprehension and Perceptual Organization factors. Analysis found no important differences in factor structure between the Chinese subjects and low-intelligence…

Assesses the relative influences of education, social environment, and current activities on the practical literacy of young adults in the United States. Shows that both early experience and current activities powerfully influence young-adult literacy and that early environmental advantages yield subsequent advantages that lead to wide disparities…

This article describes a visual assessment procedure (VAP) which evaluates capacity, attention, and processing (CAP) of infants and preschool children with visual impairments. The two-level battery considers, first, visual capacity and basic visual attention and, second, visual perceptual and cognitive abilities. A theoretical analysis of the…
