Abstract: (95 Views)
This study aimed to compare the effectiveness of Exposure and Response Prevention (ERP) and Mindfulness-Based Cognitive Therapy (MBCT) on intolerance of uncertainty and thought control strategies in individuals with obsessive-compulsive disorder (OCD). A quasi-experimental design with pretest-posttest and a control group, including a 2-month follow-up, was employed. The study population consisted of individuals with OCD seeking services at Dana and Pendar counseling and psychotherapy centers in Tehran in 2023. A total of 45 participants were purposively selected and randomly assigned to two experimental groups and one control group (15 participants per group). Measures included the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS; Goodman et al., 1989), the Intolerance of Uncertainty Scale (IUS-27; Freeston et al., 1994), and the Thought Control Questionnaire (TCQ; Wells & Davies, 1994). Data were analyzed using repeated-measures ANOVA. Results indicated significant differences between pretest and posttest/follow-up for intolerance of uncertainty and thought control strategies (p < .05), while no significant differences were observed between posttest and follow-up. ERP was particularly effective in reducing intolerance of uncertainty, whereas MBCT had a greater impact on improving thought control strategies, with both interventions demonstrating lasting effects. These findings suggest that ERP and MBCT can serve as complementary interventions to enhance cognitive and emotional functioning in individuals with OCD.
