An exploratory factor analysis of the clinical and validity scales of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) and the personality scales and modifying indices of the Millon Adolescent Clinical Inventory (MACI) was completed with a sample of 305 adolescent psychiatric inpatients. Results from a principal components analysis with Promax rotation resulted in a five factor solution interpreted as: (a) internalizing disorders, (b) externalizing disorders, (c) general pathology, (d) underreporting validity indicators, and (e) overreporting validity indicators. Implications for psychologists who use these instruments with adolescents were discussed. |
