This study investigated the relationship between perfectionism and career decision-making self-efficacy. Participants completed the Almost Perfect Scale-Revised (R. B. Slaney, K. G. Rice, M. Mobley, J. Trippi, & J. S. Ashby, 2001) and the Career Decision-Making Self-Efficacy-Short Form (N. E. Betz, K. L. Klein, & K. M. Taylor, 1996). Adaptive perfectionists had higher levels of career decision-making self-efficacy than did maladaptive perfectionists and nonperfectionists. There was no difference between maladaptive perfectionists and nonperfectionists in career decision-making self-efficacy. Findings add to a growing body of research that suggests perfectionism has adaptive and maladaptive components. Implications for counseling and limitations are discussed. (Contains 2 tables.)
