Background: The latest recommended psychological choice for the treatment of OCD is a therapeutic intervention. The metaanalytic study has found that the strongest degree of scientific evidence for CBT is the effect of OCD psychiatric therapies. We conducted the present study to examine the efficacy of group cognitive-behavioral therapy in patients with enhanced obsessivecompulsive disorder.
Methods: The study was a quasi-experimental with a manipulate group, pre-test, and post-test. 32 women were referred to counseling offerings and psychological services in Bandar Abbas province from November 2019 to April 2020, who were purposefully chosen from the 80 individuals narrowed down according to the inclusion criteria. Afterwards, they were randomly (by envelopes) assigned to the experimental and control groups. The experimental group (n=16) was treated with cognitivebehavioral therapy for 12 weekly 90-minute sessions while the control team (n=16) obtained no treatment. At the beginning of the study, after 10 weeks, all the participants were tested with the Yale-Brown Obsessive-Compulsive Questionnaire. In addition to descriptive statistics, standard deviation, and the mean and inferential statistics, we employed one-way analysis of covariance and LSD. For the statistics analysis SPSS software program model 18 was used.
Results: In the current study, the mean and standard deviation of the ages were 26.78±2.80 in the experimental team and 28.50±3.56 in the control group, respectively. We discovered a significant effect in the experimental group’s obsessive-compulsive signs following the cognitive-behavioral therapy (P=0.005). In addition, the suggested ratings for the participants in the experimental team were significantly lower than those in the control group (p <0.001).
Conclusion: According to the findings, it could be inferred that cognitive-behavioral therapy could significantly reduce OCD symptoms. It is recommended that the therapists, particularly in Iranian clinicians, apply this method.
