We document a typology of perfectionism in a sample of academically talented adolescents and directly examine its relationship to indices of psychiatric symptomatology, adjustment, self-esteem, and coping. Adolescents enrolled in a state-funded residential academy for academically gifted high school students (N = 141) responded to the Multidimensional Perfectionism Scale (Frost, Marten, Lahart, & Rosenblate, 1990), the Hopkins Symptom Checklist, the Mastery Coping and Superior Adjustment scales from the Self-Image Questionnaire for Young Adolescents, the Perception of Personal Security and Academic Competence scales from the Self-Esteem Index, and the Coping Inventory (COPE). A 2-step cluster analysis of perfectionism scores revealed four clusters: Mixed-Adaptive (n = 51), Mixed-Maladaptive (n = 20), Pervasive (n = 30), and Self-Assured Nonperfectionist (n = 39). The Pervasive and Mixed-Maladaptive clusters showed a uniformly poor profile of mental health, adjustment, and coping relative to Mixed-Adaptive and Nonperfectionists. The Mixed-Adaptive cluster reported greater academic competence and superior adjustment than did the Nonperfectionist cluster, although these cluster groups were statistically similar on other dimensions of mental health and adjustment. These results suggest that maladaptive perfectionism takes two forms: pervasive and mixed. Implications for intervention and directions for future research are discussed.
