Multivariate distributions are studied in which all bivariate regressions can be linearized by separate transformation of each of the variables. A two-stage procedure, first scaling the variables optimally and then fitting a simultaneous equations model, is studied in detail. (SLD)

Subjected Modified World Affairs Questionnaire (MWAQ) to comparable common factor analysis which identified five factors: civil defense, escalation, nuclear war outcome, probability/worry, and patriotic. Alpha coefficients and test-retest reliability were determined to be adequate for the first four subscales. Acceptable discriminant validity and…

Satisfactory results for interpersonally incomparable ordinal survey responses can be obtained by assuming that rankings are based upon a set of multivariate normal latent variables that satisfy factor or ideal point models of choice. Two statistical methods based upon those assumptions are described and illustrated via simulations. (TJH)

Observational ratings of 112 preschool student teachers on 9 teaching behaviors were factor analyzed to yield 4 underlying latent variables: facilitating, interpersonal, interactive, and flexible behaviors. The latent variables were positively correlated with each other. A path diagram illustrates the relationships among teaching behaviors and…

The parameters of full-information item factor models of varying dimensionality and mixed-measurement models of varying numbers of latent classes were estimated in 1,000 responses to a measure of Positive Interpersonal Engagement. The most appropriate representation of the data and deciding between mixed-measurement and dimensional representations…

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)
