Perfectionism dimensions as predictors of symptom dimensions of obsessive-compulsive disorder

Abstract

The correlation between obsessive-compulsive disorder (OCD) and perfectionism is well documented, yet it remains unclear if dimensions of perfectionism vary as a function of OCD symptom dimensions. To this end, the present study investigated the unique associations between dimensions of perfectionism (i.e., concern over mistakes, doubts about actions, personal standards, parental criticism, parental expectations, and organization) and OCD symptom dimensions (i.e., hoarding, washing, checking, ordering, obsessing, and neutralizing). The study included adult patients with OCD (N = 46) from a residential OCD treatment program. Consistent with previous research, doubts about actions was a significant predictor of overall OCD severity and OCD checking symptoms. The organization dimension of perfectionism was a significant predictor of OCD ordering symptoms. The current study provides evidence for the unique relationships between OCD symptoms and perfectionism dimensions that encourage a movement toward greater phenotypic specificity within existing models of OCD.
