The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) was factor analyzed using the adolescent female normative sample. A Maximum Likelihood (ML) factor analysis with an oblimin rotation produced both a 4-factor solution and a possible 8-factor solution. However, anaylsis of the eigenvalues and the Scree test plot indicated a 4-factor solution obtained the best data fit.

Factor 1 identified a general sense of maladjustment characterized by anxiety, depression, and physical complaints. Factor 2 distinguished features of social introversion, obsessive thoughts, and depression . Factor 3 described features of unusual behavior, thought disorders, and social deviance. Factor 4 reflected the need for control in terms of internal and external resources.The four factors are consistent with those previously identified by Butcher et al. (1992). Erikson 's developmental theory provides a framework for the discussion of the factors identified by the MMPI-A.
