BACKGROUND AND OBJECTIVES: Cognitive-behavioural models of obsessive-compulsive disorder (OCD) suggest that maladaptive beliefs about perfectionism play a key role in the development and maintenance of OCD. Cognitive-bias modification for interpretation bias (CBM-I) is an experimental procedure that can test this proposed causal relation.
METHODS: As such, the current study investigated whether multiple CBM-I sessions administered in different contexts can modify perfectionism biases. Undergraduate students high in OCD-related perfectionism beliefs were randomly allocated to either an experimental (n = 44) or control (n = 44) training condition and completed self-report and behavioural measures of perfectionism and OCD symptoms.
RESULTS: As predicted, relative to the control condition, participants in the experimental condition exhibited a significant decrease in perfectionism beliefs, from baseline to after one CBM-I training session, which was maintained at one-week follow-up. Contrary to hypotheses, there were no significant differences between conditions on measures of OCD symptoms and perfectionistic behaviour.
LIMITATIONS: Issues with the current study's behavioural measures may have precluded any differences between conditions.
CONCLUSIONS: Results underscore the need to further refine cognitive-behavioural models of OCD to understand the precise causal relation between beliefs and symptoms.
