Brief summary

The primary purpose of this research is to determine whether targeting perfectionism directly in treatment, using an evidenced based transdiagnostic CBT, is an effective intervention for obsessive-compulsive disorder (OCD) and elevated perfectionism; and to compare the outcomes of this with a waitlist control condition. It is hypothesized that individuals who receive the intervention will demonstrate superior outcomes as indexed by reliable change and clinically significant change, compared to wait listed participants. Data obtained whilst the ERP arm of the study was still in operation will be reported if and where appropriate for comparison purposes.

Interventions

The purpose of the study is to determine whether directly targeting elevated perfectionism traits is an effective first-line therapeutic intervention in a clinical population of OCD participants, relative to a waitlist control group. The intervention is based on the transdiagnostic intervention developed by Egan, S. J., Wade, T. D., Shafran, R., & Antony, M. M., Cognitive Behavioral Treatment of Perfectionism (2014). The intervention involves psycho-education, self-monitoring, behavioral experim

The intervention is based on the transdiagnostic intervention developed by Egan, S. J., Wade, T. D., Shafran, R., & Antony, M. M., Cognitive Behavioral Treatment of Perfectionism (2014). The intervention involves psycho-education, self-monitoring, behavioral experiments, cognitive restructuring and motivation work. Administration and duration: Group therapy sessions run by two therapists, once-weekly for 2 hours over an eight week period, plus homework exercises. Following an 8-week waitlist period, control participants receive the same intervention.
