Responsibility and perfectionism in OCD:: an experimental study

Cognitive models of obsessive-compulsive disorder (OCD) suggest a number of different variables that may play a role in the development and maintenance of obsessive compulsive symptoms [Freeston, M. H.. Rheaume, J., & Ladouceur, R. (1996) Correcting faulty appraisals of obsessional thoughts. Behaviour Research and Therapy, 34, 433-446]. This study's aim was to verify the effect of perfectionism and excessive responsibility on checking behaviors and related variables. Twenty-four moderately perfectionistic subjects (MP) and 27 highly perfectionistic subjects (HP) were submitted to a manipulation of responsibility (low and high). After each manipulation, they had to perform a classification task during which checking behaviors were observed. Results indicate that more checking behaviors (hesitations? checking) occurred in the high responsibility condition than in the low responsibility condition for subjects of both groups. After executing the task in the high responsibility condition, HP subjects reported more influence over and responsibility for negative consequences than MP subjects. These results suggest that high perfectionistic tendencies could predispose individuals to overestimate their perceived responsibility for negative events. Furthermore, perfectionism could be conceived as playing a catalytic role in the perception of responsibility. Results are discussed according to cognitive models of OCD.
