A double cross-validation design was used to study the stability of the canonical correlations between the SVIB and the MCI for male freshmen engineering students. Only the first canonical variates produced high correlations for the cross-validation samples. (Author)

Four new experimental scales of motivation were constructed by applying a modified iterative factor analytic method to item responses of 346 subjects. The scales-tentatively identified as intrinsic motivation, self-enhancement, person orientation, and goal deficiency-should have special relevance to the educational and counseling objectives of the…

Eysenck's PEN Inventory and Lanyon's Psychological Screening Inventory were given to groups of male and female American undergraduates from a state university. A factorial analysis of the intercorrelations showed that three major factors could account for the bulk of correlations among the nine differently labeled characteristics covered by the…

When total scores on the California Preschool Social Competency Scale (CPSCS) of disadvantaged children attending New York State experimental prekindergarten programs in 1975-76 were replaced by factor scores derived through principal component analysis, exposure time had no significant relationship to three components of the scale:…

The purpose of this paper is to examine the capabilities of various procedures for sorting dichotomously-scored items into unidimensional subjects. The procedures include: factor analysis, nonmetric multidimensional scaling, cluster analysis, and latent trait analysis. Both simulated and real data sets of known structure were used to evaluate the…
