This study tested models of perfectionism predicting psychological distress and academic adjustment and moderators and mediators of those associations in 2 successive cohorts of high-achieving university honors students (N ϭ 499). Participants completed measures early and late in the semester. Adaptive (high standards) and maladaptive (self-critical perceptions of inadequacy in meeting performance expectations) dimensions of perfectionism were found to be significantly associated, in generally expected directions, with concurrent and prospective perceived stress, social connectedness, depression, hopelessness, and perceived academic adjustment. However, some perfectionism effects were reduced when earlier psychological distress and adjustment were controlled in analyses predicting later distress and adjustment. Several effects were moderated and at least partially mediated by perceived stress and social connection. The results suggest several counseling implications for high-achieving, perfectionistic students.

The Adaptive/Maladaptive Perfectionism Scale (AMPS; K.G. Rice & K.J. Preusser, 2002) was developed on samples of 9-to 11-year-old children. A primary purpose of the current research was to examine whether the AMPS could be useful in studies of adolescents, and in particular, studies of adolescent depression. This study of 145 early adolescents revealed (1) a somewhat different AMPS factor structure than has been evident in studies of younger children; (2) no significant mean differences between boys and girls on perfectionism, although girls were significantly more depressed than boys; (3) a pattern of perfectionism-depression correlations that differed somewhat between boys and girls; and (4) several interactions of different dimensions of perfectionism in accounting for depression. Results are discussed by addressing differences between children and adolescents in school cultures, physical and psychological changes from childhood to adolescence, and the importance of considering the positive as well as the negative aspects of perfectionism among school-age children.
