Research and Training

Dr. Hewitt is most well-known for his work on perfectionism with Dr. Gordon Flett and Dr. Samuel Mikail and has developed not only several models of perfectionism but also the treatment of perfectionism. Moreover, Dr. Hewitt, Dr. Flett, and Dr. Mikail have developed numerous clinical measures of perfectionism of the components of the perfectionism construct, including the Multidimensional Perfectionism Scale (MPS), the Perfectionistic Self Presentation Scale (PSPS), the Perfectionism Cognitions Inventory (PCI), and similar scales for use with children. These measures have been used widely in both research and clinical settings. Dr. Hewitt, his colleagues, and graduate students have conducted extensive research on the construct of perfectionism as a multidimensional and multilayered personality style, the negative outcomes of perfectionism in psychological, physical health, relationship, and achievement domains, and both the assessment and treatment of perfectionistic behavior. He, along with Dr. Samuel Mikail, developed Dynamic Relational Psychotherapy that has been evaluated and refined empirically for treatment of perfectionism and associated psychopathology. He regularly talks and conducts workshops on perfectionism and treatment internationally and the American Psychological Association has produced several published videos of Dr. Hewitt demonstrating the treatment.

Dr. Hewitt’s Perfectionism and Psychopathology Laboratory at the University of British Columbia is currently focusing on several large scale studies assessing and refining the assessment and treatment of perfectionism and addressing the development of perfectionism in children and adolescents. In addition, he is involved in many collaborative projects throughout Europe and the U.S.A dealing with various clinical issues pertaining to perfectionism and its pernicious outcomes.
