Abstract(s)
O Sumário Estrutural (SE) do MMPI-A foi desenvolvido como forma de agregar a informação relativa à
personalidade e psicopatologia que este instrumento proporciona. Neste estudo, replicámos os estudos de
Archer, Belevich e Elkins e de Archer e Krishnamurthy, com a amostra normativa norte-americana do
MMPI-A, que basearam o SE original. Assim, analisámos a estrutura factorial dos resultados do MMPI-A
obtidos com uma amostra, não clínica, de adolescentes portugueses (N=572). A análise factorial revela uma
organização das escalas e subescalas do MMPI-A numa estrutura consistente com a do SE original. Os oito
factores identificados, que explicam 72% da variabilidade dos resultados, foram designados de
Desajustamento Global, Desinibição/Potencial Excitatório, Desconforto Social, Problemas
Comportamentais, Preocupações com a Saúde, Imaturidade, Alienação Familiar e Conflitualidade, e
Evitamento Social. Os resultados são discutidos face à utilidade do SE na avaliação com o MMPI-A e à
investigação da personalidade e da psicopatologia em adolescentes portugueses.
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 MMPI A 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.
