Abstract

Objective: The construct of perfectionism has long been related to Obsessive-Compulsive Personality Disorder (OCPD), though research has not considered how OCPD could distinguish individuals with elevated perfectionism. The aim of this study was to evaluate clinical differences between those with and without OCPD in a sample of individuals with elevated perfectionism.

Methods: Seventy-four university students with elevated perfectionism completed a diagnostic assessment and several self-report measures of clinical characteristics and were randomly assigned to complete an exposure-based treatment for perfectionism or waitlist. Thirty-four (45.95%) participants met DSM-IV diagnostic criteria for OCPD.

Results: Compared to those without OCPD, individuals with OCPD had higher levels of general and specific domains of perfectionism and higher levels of social anxiety. OCPD diagnosis was also associated with higher rates of current anxiety disorder. Importantly, those with and without OCPD showed comparable benefits from treatment.

Conclusions: This study provides novel evidence of the role of OCPD in perfectionism and demonstrates the efficacy of a perfectionism-oriented treatment in individuals with OCPD.Key pointsWe examined the role of obsessive-compulsive personality disorder (OCPD) in a high perfectionism sample.OCPD was associated with higher perfectionism and personal standards.OCPD was also associated with higher social anxiety and higher rates of current anxiety disorder.Those with and without OCPD had comparable responses to an exposure-based treatment for perfectionism.
