Dimensionality of observer ratings on the California Adult Q-set.

The dimensionality of personality ratings on the California Adult Q-set (CAQ) is examined in a sample of 940 subjects. Solutions of between 5 and 15 factors are examined; interrater agreement is assessed for items, factors, and items partialing factors. Results suggest that the 5 personality factors are important yet not exhaustive in accounting for common factor variance in the CAQ. Furthermore, interjudge agreement extends beyond the 5 dimensions. Likely explanations for these results are considered, and implications are addressed
