Shared variance in the California Psychological Inventory and the California Q-Set.

On a composite sample of 940 individuals assessed at the Institute of Personality Assessment and Research, a series of analyses examining the extent and nature of correspondence between (a) observer descriptions of personality using the California Q-Set and (b) scores on the standard scales of the self-report California Psychological Inventory was performed. The instruments converged in the domains of social competence (vs. interpersonal inadequacy), rectitude (vs. rebellion), intellectual openness, tender-mindedness (vs. tough-mindedness), and emotional expressiveness.
