The aim of the present study was to investigate the effect of cognitive-behavioral therapy on reducing perfectionism and cognitive error of thought-action equivalence in women with obsessive-compulsive disorder. The study was conducted using a quasi-experimental method with a pre-test-post-test design with a control group. The statistical population included all women with obsessive-compulsive disorder referring to Sarohana Clinic in Pasdaran district of Tehran in 1404. The research sample was selected using an accessible and purposeful method and included 45 people who were randomly assigned to three groups (cognitive-behavioral therapy, short-term psychodynamic therapy, and control). The data collection tools included the revised cognitive error of thought-action equivalence scale of Shafran et al. (1996), the Ahvaz Perfectionism Questionnaire, and the Maudsley Obsessive-Compulsive Disorder Questionnaire (1977). The cognitive-behavioral therapy intervention was implemented in eight group sessions, once a week for 40 minutes for the experimental group. Data were analyzed using multivariate analysis of covariance and post hoc tests. The findings showed that cognitive-behavioral therapy significantly reduced perfectionism and cognitive error of thought-action equivalence (moral dimensions, probability for self and probability for others) compared to the control group. The results of this study indicate the effectiveness of cognitive-behavioral therapy in reducing harmful cognitive variables in women with obsessive-compulsive disorder and can be used as an effective intervention in improving the symptoms of this disorder.
