The MAPI as a treatment outcome measure for adolescent inpatients

Abstract

The Millon Adolescent Personality Inventory (MAPI; Millon, Green, & Meagher, 1982) was administered at admission and discharge to 215 hospitalized adolescents. Significant mean score differences were found for both internalizing (affective disorder) and externalizing (disruptive behavior disorder) adolescents. Consistent with theory, internalizing adolescents reported significantly greater distress at both admission and discharge than externalizing adolescents. Finally, test‐retest reliability coefficients were somewhat lower than those reported previously (Millon et al., 1982) for hospitalized adolescents.
