MMPI correlates of Exner's Egocentricity Index in an adolescent psychiatric population

This research examined the relationship between Exner's Egocentricity Index (EI) and Minnesota Multiphasic Personality Inventory (MMPI) Scales 2, 4, and 9 in an adolescent psychiatric population. Subjects with a low EI had significantly higher MMPI Depression (D) scale elevations compared to those with a high EI. Furthermore, of the adolescents who had Scale 2 scores in the clinical range, 68% also had an EI in the bottom half of the distribution. There was no relationship between the EI and MMPI scales 4 and 9. These findings are discussed in light of the generally poor correlations between MMPI and Rorschach variables.
