A Bayesian procedure is given for estimation in unrestricted common factor analysis. A choice of the form of the prior distribution is justified. The procedure achieves its objective of avoiding inadmissible estimates of unique variances, and is reasonably insensitive to certain variations in the shape of the prior distribution. (Author/BJG)

Two experiments attempted to determine the importance of the integrating theme in memory for a prose passage. (Editor)

The college student drug users are likely to be male, urban, Jewish or nonreligious, humanities or social sciences majors, upper middle class, politically liberal or radical, and they are likely to rate their general health as somewhat lower than average. Grades and class in college were not consistently related to drug use. (Author)

Represents an attempt to jointly scale both political issues and political candidates in the same space, using Tucker's (1972) three-mode mutidimensional scaling model. (Author/RC)

Procedures developed by Joreskog for studying similarities and differences in factor structures between different groups were applied to data from a study by Thurstoen to investigate the sampling stability of a hypothesized isolated configuration. The hypothesis of an isolated configuration was rejected but not by much. (Author/RC)

During the last 15 years, there has been a steady increase in the popularity and sophistication of the confirmatory factor analysis approach to multitrait-multimethod (MTMM) data. However, important problems exist, the most serious being the ill-defined solutions that plague MTMM studies and the assumption that so-called method factors primarily…

To test whether or not the factor structure of the Adaptive Behavior Scale (Part I) (ABS) differs when community-based mentally retarded subjects are used rather than institutionalized retarded subjects, the ABS was administered to 100 mentally retarded adults living at home and being served by community daytreatment programs. A principle…

The Snijders-Oomen Nonverbal Intelligence Test (SON) was administered to 251 deaf children (6-15 years old) and 101 hearing children (10-12 years old) in Israel. The SON was judged appropriate for measuring cognitive functioning in the deaf because it requires no verbal instructions or responses and includes a measure of abstract thinking ability.…

A "doubly-centered" raw data matrix is one for which both columns and rows have both unit variance and means equal to zero. The factor scores from one analysis are the same as factor pattern coefficients from the other analysis except for a variance adjustment. This study explored an extension of the reciprocity principle which may have…

This study attempted to clarify the structure of mathematical abilities through reanalysis of 48 factor-analytic studies. The factors were compared in six families: General, Numerical, Reasoning, Spatial, Verbal, and Mathematical. Eleven data sets were reanalyzed, with principal factor analysis followed by graphical rotation to oblique, simple…

Using the personality trait versus state distinction as a substantive context, the fit of the factor analytic model to difference score data is investigated and found to be quite good. Methodological issues related to properties of difference scores and their implications for personality research are briefly discussed. (Author)

Second order personality factors (those that do not appear in children) were investigated in male and female high school students. Two forms of the high School Personality Questionnaire were used as the basis of the study. (DP)

A factor analytic study was designed to examine the factor structure of a battery of 17 tests administered to 100 students at the primary, intermediate, and advanced (grades 7-10) levels and to determine differences in factor structures for the three groups. The tests, measures of academic achievement, included the Wechsler Intelligence Scale for…
