The Citizenship Knowledge Test contains subtests designed to measure subareas of the overall construct of citizenship knowledge. Two factor analysis studies indicated that the test is construct valid. It can, therefore, be used as a general measure of the construct citizenship knowledge. (Author/RM)

Procedures suggested by Joreskog for performing exploratory factor analysis were evaluated. An in-depth analysis of psychological test scores of junior high school students was conducted. Procedures using exploratory and confirmatory techniques were found to produce misleading results in some instances. (Author/DWH)

The details of EM algorithms for maximum likelihood factor analysis are presented for both the exploratory and confirmatory models. An example is presented to demonstrate potential problems in other approaches to maximum likelihood factor analysis. (Author/JKS)

Despite Spitz's (1982) contention that his conclusions are necessarily in conflict with those arising from factor analysis, this article demonstrates how results from factor analysis can provide insights into data he cites. (Author/MP)

Reports on a factor analysis of homogeneously grouped behavior problems for two large samples of Chinese adolescents during their junior high school years. Cross-culturally compares this factor organization with those found for non-Oriental children and adolescents. (MK)

Applies a variety of factor analytic approaches to data obtained from the Structured Pediatric Psychosocial Interview (SPPI), an instrument designed to gain information about children's social background and the process by which they relate affective distress. Subjects were independent samples of 500, 400, 519 and 1,000 pediatric patients and…

A new method is proposed for a simultaneous factor analysis of dichotomous responses from several groups of individuals. The method makes it possible to compare factor loading pattern, factor variances and covariances, and factor means over groups. Generalized least squares is used as the estimation procedure.

The practicality of using the EM algorithm for maximum likelihood estimation of item parameters in the marginal distribution is presented. The EM procedure is shown to apply to general item-response models. (Author/JKS)

Investigated the correspondence between stage changes hypothesized by the Kubler-Ross theory and the perception of the course of illness by seriously ill patients and their spouses. Supported the use of Q-methodology as a research procedure for investigations of terminal illness. (Author)

A multidimensional scaling analysis of 21 work outcomes yielded a latent structure with three dimensions: value attached by society, level of psychological need met, and extent the outcome is inherent in the work itself. Results suggest a multidimensional model of work outcomes is more useful than a categorical approach. (Author)

An empirical investigation of the statistical procedure entitled nonlinear principal components analysis was conducted on a known equation and on measurement data in order to demonstrate the procedure and examine its potential usefulness. This method was suggested by R. Gnanadesikan and based on an early paper of Karl Pearson. (Author/AL)

Teachers' ratings of their students on a 40-item learning style checklist based on M. Rosenberg's descriptive theory of four learning styles were factor analyzed for a predominantly Black sample of 377 eighth grade students. (Author/PHR)

The partial correlation coefficient is derived analytically under exemplary factor patterns. In these patterns, variables are described as an additive composition of a set of orthogonal factors, including general, common, and specific factors. Viewed in this framework, it is evident that the partial correlation may yield spurious results.…

A jackknife-like procedure is developed for producing standard errors of estimate in maximum likelihood factor analysis. Unlike earlier methods based on information theory, the procedure developed is computationally feasible on larger problems. Examples are given to demonstrate the feasibility of the method.

The relationship between the Michigan Alcoholism Screening Test (MAST) and the subject's sex and income was significant. If male or poor, he was more likely to receive a higher score on MAST. There was no significant correlation with age, marital status, education, or duration of residency. (Author/BEF)
