The study aim was to explore the dimensional structure of the California Q-Set, a widely use Q-sort procedure. The data analyzed consisted of the composited CQS descriptions of the male sample and the female sample during their high school years as reported by Block in his Lives Through Time. The 104 variables were intercorrelated across the 160 cases and analyzed by the method of principal components with a scree test criterion. The eight interpretable factors reported were rotated by the Promax procedure. The clear-cut simple structure was defined by 94 of the statements. The dimensions identified were found to resemble many behavioral rating factors reported for several inventories.
