Two confirmatory maximum likelihood factor analytic models of the Personality Research Form-E are presented and discussed for the men's and women's standardization data. Overall, the patterns of correlations within each data matrix are highly similar, but the factor patterns, factor intercorrelations, as well as the error variances, do differ.…

Presents data on the interrater reliability, internal consistency, factor structure, and discriminant validity of the Cognitive Therapy Scale (CTS). Results indicate that the CTS can be used with only moderate interrater reliability but the aggregation can be used to increase reliability. The CTS is highly homogeneous and provides a relatively…

Presents a five-factor, structural model of the Personality Research Form-E for 140 university undergraduates. All factors demonstrated an excellent level of similarity to those previously reported for other forms of the PRF, as well as to the conceptual scheme developed by Jackson (1974). (Author/JAC)

Administered the Aftermath of Suicide Instrument to 54 adults. Factor analysis of their responses identified five factors, but only one of these was similar to any of the original factors. While the content of the Aftermath of Suicide Instrument remains valid, its factorial structure requires further clarification. (JAC)

Examined the Wechsler Intelligence Scale for Children (Revised) factorial similarity for a referred sample of Black (N=430) and White (N=274) students and compared the factor structure of each group with the pattern identified for the standardization sample. Results showed the patterns for Blacks and Whites were quite similar. (JAC)

Discusses Guttman's index of indeterminacy in light of alternative solutions which are equally likely to be correct and alternative solutions for the factor which are not equally likely to be chosen. Offers index which measures a different aspect of the same indeterminacy problem. (ROF)

Examples are presented in which it is either necessary or desirable to transform two sets of orthogonal axes to simple structure positions by means of the same transformation matrix. A solution is outlined which represents a two-matrix extension of the general "orthomax" orthogonal rotation criterion. (Author/RC)

The main objective of this study is to investigate the role of four different modes of representation in mathematical problem solving (MPS), and more specifically to develop a model, which provides information about the effects of these representations in the solution procedures of one-step problems of additive structures. Data were collected from…

Structural changes in an English as a Second Language (ESL) 30-item reading comprehension test were examined through principal components analysis on a small sample (n=31) of students. Tests were administered on three occasions during intensive ESL training. Principal components analysis of the items was performed for each test occasion.…

A promising new teacher self-efficacy instrument, the Ohio State Teacher Efficacy Scale (OSTES) (M. Tschannen-Moran and A. WoolfolkHoy, in press) was critically evaluated regarding its development and submitted to confirmatory factor analysis (CFA). Participants were 183 inservice teachers in Texas and Washington, DC, most of whom taught primary…

The purpose of the present study was to determine the ability organisation for adults of various ages through a hierarchial factor analysis of WAIS subtest intercorrelations for subjects from early adulthood through old age. (Author)

Factors identified for middle-class youngsters were found to be remarkably similar to those generated by their lower-class counterparts. (Authors)

Results of this research, while partially supportive of the general construct which the POI purports to measure, raises some questions about necessity of, or relevance of, the many scales of the inventory. (Authors/MB)

A factor rotation scheme is presented which has a property that is interesting for examining factor-structure hypotheses. Given several clusters of tests the orthogonal bounds scheme produces factors which contains these clusters in some optimal sense. (Author)
