The problem of demonstrating replicability of factor structure across random variables is addressed. Procedures are outlined which combine the use of random subsample replication strategies with the correlations between factor score estimates across replicate pairs to generate a coefficient of replicability and confidence intervals associated with…

This study investigated the relationship between the dimensionality of behaviorally anchored scales during construction and during their use. It was hypothesized that as the agreement among raters in assigning behaviors to dimensions increased, there would be an increase in the stability of the structure of the dimensions and in their independence…

Additive two-factor conjoint measurement is derived from axioms that do not include unrestricted solvability or a condition on interlocked standard sequences. (Author)

An empirical sampling distribution of the statistic average trace (E'E) for various orders of A matrices was developed through a Monte Carlo approach. A method is presented which can be used as a guideline in determining whether factor structures obtained from two data sets are congruent. (Author/DEP)

The construct validity of extraversion-introversion was explored, as measured by the Myers Briggs Type Indicator (MBTI) and the Eysenck Personality Inventory. Findings supported the complexity of extraversion-introversion. Two MBTI scales, Extraversion Introversion and Judging Perceiving, were factorially valid measures of impulsivity…

The purpose of the two studies described in this paper is to validate dimensionality of the job involvement construct through empirical testing of existing measures. Cumulative results of these studies suggest that job involvement is a unidimensional construct which can be operationalized in terms of one's psychological identification with work.…

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.…
