Abstract

Introduction: This study aimed to determine the effects of CBT and psychodynamic therapy on ego functioning and psychological well-being in patients with OCD.  .
Methods: This semi-experimental study was conducted with a pre-test, post-test, and two-month follow-up design, along with a control group. The study population consisted of all OCD patients who visited a psychological clinic in Tehran in 2024. The sample size was determined using Cohen’s table. With a confidence level of 95%, an effect size of 0.30, and a statistical power of 0.83, the sample size for each group was determined to be 12. However, considering the possibility of sample attrition and to increase the generalizability of the results, the sample size was set at 15 per group. In the first stage, 45 participants were selected through convenience sampling, and in the second stage, they were randomly assigned into two experimental groups (15 each) and one control group (15) through a simple random drawing.
Results: The results of the study indicated that CBT and psychodynamic therapy had a significant effect on the dimensions of psychological well-being and ego functioning in individuals with OCD (P<0.001), and the effectiveness of both methods was similar (P>0.05). 
Conclusion: Based on the results, psychologists and psychiatrists can consider the use of cognitive-behavioral and psychodynamic therapies alongside other treatments for these individuals
