The pattern of correlations between subtests suggests that several of the aptitudes are of doubtful validity. In no case was it possible to extract more than three adequately determined factors. (Author)

A new method to estimate the parameters of Tucker's three mode principal component model is discussed, and the convergence properties of the alternating least squares algorithm to solve the estimation problem are considered. An example is presented. (Author/JKS)

The values of computer-based content analysis techniques and the application of a variety of analytical methods in areas related to health education are discussed. (JD)

A chain of lower bound inequalities leading to the greatest lower bound to reliability is established for the internal consistency of a composite of unit-weighted scores (such as a test). Algorithms for obtaining various reliability coefficients are presented. (Author/JKS)

To assess the stability of the factor structure of the Instructional Improvement Questionnaire (IIQ), factor analyses were run for 1973, 1974, and 1975 results, partialling out three variables: expected grade, percent taking the course as an elective, and student's year. The factors were stable over the three years. (Author/BW)

Factors extracted from identical items administered to similar but not identical samples should be comparable to be used as summary measures. Correlation between duplicate factor scores calculated using weights from identical factor analyses of two samples provides a comparability coefficient, a more direct measure than the congruence coefficient.…

A descriptive study of factors in the lifestyle of 50 couples married an average of 55.5 years and an average age of 79 years provided data for this report. Independence, commitment, companionship, and qualities of caring were significant elements in these long-lasting marriages. (Author)

A reanalysis of a structural equation model of the development of intellectual abilities is presented. The original model emphasized four different constructs of intelligence; the reanalysis emphasized a general factor model. (Author/JKS)

This study uses a multifactorial model of locus of control to examine the attribution of causality in Black and White students in Zambia and Zimbabwe-Rhodesia. (Author/MC)

Multidimensional scaling and factor analysis were applied to Rest's objective test of Kohlbergian moral development. The responses of 160 junior high, senior high, college undergraduate, and graduate students were analyzed in order to investigate whether stage and item scores displayed a hierarchial sequential structure. (Author/SS)

High intercorrelations among the six subtests of the Pictorial Test of Intelligence raise questions regarding the construct validity of the instrument. A factor analysis was performed. A single factor with stable factor loadings emerged. (Author/JKS)

Presents a demographic analysis of the paths to remarriage--the extent and timing of remarriage, social factors associated with remarriage, and the impact of the event which preceded remarriage (divorce or widowhood). (Author)

The factor analytic model of the practitioner-oriented "Opinions about People" was tested with a population of gerontological practitioners. An analysis eliminated nine items not warranting inclusion in the instrument, redistributed the factors, and brought out a completely new factor. (Author)

The importance of measuring the size of an effect for fixed effects factorial analysis of variance designs is emphasized. Technical issues in such measurement are considered and examples are provided. (Author/JKS)

Several advantages to the use of different kinds of factor scores as independent variables in a multiple regression equation are reported. A computer program is presented which will calculate a regression equation using a variety of factor scores. (Author/JKS)
