Key findings
- 1991
With Gordon Flett, Hewitt proposed a three-dimensional model of perfectionism — self-oriented, other-oriented, and socially prescribed — demonstrating that socially prescribed perfectionism (believing others demand perfection from you) shows the strongest links to depression and anxiety. ↗
- 2002
Hewitt and Flett's edited volume synthesized two decades of perfectionism research, documenting how perfectionism functions as a transdiagnostic risk factor — amplifying distress across depression, anxiety disorders, eating disorders, and interpersonal dysfunction. ↗
