Many researchers acknowledge the prominent role that factor analysis can play in efforts to establish construct validity. Data can be analyzed with no preconceived ideas about the underlying constructs of structure of the data. This approach is exploratory factor analysis, Another approach is used when the researcher has an understanding of the…

A relatively simple technique for assessing the convergence of sets of variables across method domains is presented. The technique, two-step principal components analysis, empirically orthogonalizes each method domain into sets of components, and then analyzes convergence among components across domains. (Author)

This study investigated the factorial composition of responses to the Life Style Analysis (LSA) in two normal and four clinical groups. (Author)

The factor structures of the College Student Questionnaire were investigated for three large samples of freshmen. The results demonstrated the variety of information contained in these instruments and questioned the choice of some items used in the suggested scales. (Author)

The factor analytic studies that have been done with the Millon Clinical Multiaxial Inventory (MCMI), a 175-item paper-and-pencil test designed to evaluate symptomology in psychiatric patients, have been problematic in that the test's high inter-scale correlation could lead to an artificially robust factor structure. The present investigation…

A factor analysis of the correlation matrix for the subsets of WPPSI was carried out for each of the age groups between 4 and 6 1/2 years. (Editor)

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.…
