Análise Factorial do MMPI-A: Replicação do Sumário Estrutural Original com uma Amostra Portuguesa.

The Structural Summary (SS) of the MMPI-A has been developed as a strategy to aggregate the information about adolescent personality and psychopathology that the MMPI-A provides. In this study, we analyzed the factorial structure of the MMPI-A at scale and subscale levels with a nonclinical sample of 572 Portuguese adolescents. We replicated the studies of Archer, Belevich, and Elkins, and of Archer and Krishnamurthy, with the American MMPI-A normative sample. The factorial analysis revealed an organization of the MMPIA scales and subscales in eight factors, in a structure consistent with the MMPI-A SS, and which explains 72% of the results variability. We named the eight dimensions as follows: General Maladjustment, Disinhibition / Excitatory Potential, Social Discomfort, Behavioral Problems, Health Concerns, Immaturity, Conflictuality and Familial Alienation, and Social Avoidance. The results are discussed regarding the clinical utility of the SS in psychological assessment processes with the MMPI-A, and with Portuguese adolescents. [ABSTRACT FROM AUTHOR]
