The relationship between psychometric intelligence and the five-factor model of personality in a rehabilitation sample.

WAIS-R and NEO Personality Inventory (NEO-PI) scores obtained from 85 rehabilitation clients of the Evaluation and Development Center of Southern Illinois University's Rehabilitation Institute were utilized to examine the relationship between psychometric intelligence and personality. Correlational analyses revealed that the NEO-PI Openness domain and its six facets significantly correlated with WAIS-R FSIQ, VIQ, PIQ, and 9 of the 11 subtests. Multiple regression analyses showed that the five NEO-PI domains accounted for significant proportions of WAIS-R, FSIQ, VIQ, and PIQ score variance. The NEO-PI Openness domain was found to be the best predictor of WAIS-R FSIQ, VIQ, and PIQ scores. The study concludes with a discussion of the meaning and implications of the findings and suggestions for future research.
