Flett Avi Besser Richard A. Davis York University Paul L. Hewitt University of British Columbia ABSTRACT: The current research investigated the associations among di- mensions of perfectionism, unconditional self-acceptance, and self-reported depression. A sample of 94 students completed the Multidimensional Perfec- tionism Scale, the Unconditional Self-Acceptance Questionnaire, and a self- report depression measure. Correlational results indicated that all three trait dimensions of perfectionism (i.e., self-oriented, other-oriented, and socially prescribed perfectionism) were associated negatively with unconditional self- acceptance. Also, as expected, depression was associated with relatively low unconditional self-acceptance. Finally, a path analysis revealed that uncondi- tional self-acceptance mediated the association between socially prescribed perfectionism and depression, and other-oriented perfectionism was found to affect depression only indirectly through its association with low levels of self-acceptance. The findings indicate that perfectionists evaluate themselves in terms of a contingent sense of self-worth, and as such, they are vulnerable to psychological distress when they experience negative events that do not affirm their self-worth. This research was supported by a major research grant from the Social Sciences and Humanities Research Council (SSHRC) of Canada and a sabbatical leave fellowship from York University to the first author.
