Dr Paul Hewitt

Canadian clinical psychologist at UBC whose research on perfectionism — distinguishing self-oriented, other-oriented, and socially-prescribed perfectionism — has produced the most nuanced and clinically useful framework for understanding perfectionism's psychological costs.

Developed the multidimensional perfectionism framework that distinguishes the perfectionism you impose on yourself, the perfectionism you impose on others, and the perfectionism you believe others impose on you — demonstrating that these have different psychological correlates and clinical implications.
