The appropriate use of exploratory factor analysis (EFA) necessitates thoughtful researcher judgment concerning a number of analytic decisions. This paper reviews some of the fundamental decisions necessary to conduct an EFA and examines reporting practice in published research across four journals. In general, insufficient information was given…

Personality structure, as measured by the Preschool Personality Questionnaire, was studied in preschool children. Two studies are reported which discuss factor analysis, including the ability factors of the PSPQ. (ST)

A shortcut formula for the computation of "coefficients of invariance" in the comparison of factor structures is presented. A limitation of the coefficient of invariance is pointed out in the case of comparing two first principal components. (NE)

A counterexample is produced to a conjecture by K. G. Joreskog concerning sufficiency conditions for uniqueness of a restricted factor matrix. A substitute condition is stated and proved for the most common situation where the restricted elements are specified to be zero. (Author)

This is a report of an experimental investigation of the interrelationships and effects of consideration and initiating structure in effective leadership. (LN)

Factor analysis of artificial data is shown to yield an incorrect number of dimensions, seven, while monotonicity analysis recovered completely and accurately the fact that the data was generated from two latent dimensions. (RF)

The study investigated the degree to which errors of scaling and selection depress the linear relationship and whether the reduction in the magnitude of r differs with the type of error. Results indicated that various scaling errors caused considerable discrepancy in the measurement of underlying relations, but the effect of non-normality was…
