Identity and shame in body dysmorphic disorder as compared to obsessive-compulsive disorder

Abstract

BackgroundIdentity disruption and internalised shame may be important factors in explaining possible psychological mechanisms that underlie body dysmorphic disorder (BDD). These factors have also been linked to obsessive-compulsive disorder (OCD), a condition closely related to BDD. However, these factors have not been specifically examined in BDD, nor contrasted between BDD and OCD. MethodsWe compared identity functioning and internalised shame among 26 BDD, 22 OCD and 26 healthy control participants, and examined clinical correlates in both disorders. ResultsFindings demonstrated increased identity disruption and internalised shame in BDD and OCD relative to controls, and increased internalised shame in BDD relative to OCD. In both disorders, shame and identity disruption was correlated with suicidal ideation, depression, stress, and anxiety. In BDD only, increased identity disruption correlated with poorer insight, and increased internalised shame correlated with more severe BDD symptoms and poorer illness insight. ConclusionsThese data suggest that internalised shame may have important and specific relevance to BDD, and more general relevance to OCD. Moreover, identity disruption may represent an area meriting further research attention in both BDD and OCD. Clinical implications include the potential benefits of addressing internalised shame and identity problems in the treatment of both disorders.
