Analyzed data from a longitudinal twin study of personality using Wilson's repeated measures analysis of variance for twin data obtained from 42 pairs of twins. Average age of Ss in adolescence was 15.9 yrs, and at follow-up 27.9 yrs. Genetic influences on the MMPI and the California Psychological Inventory (CPI) profile contour and profile elevation at adolescence and at adulthood, and on the age-to-age changes in profile contour and profile elevation, were examined. Results provide evidence of significant genetic variance in the organization of personality as reflected by the CPI profile contour and in the global facets of personality reflected by the MMPI and CPI profile elevations.
