en رويكرد شناختي رفتاري Cognitive behavioral پژوهشي Original Research Article <strong>Objective</strong>: This study aimed to compare the effectiveness of schema therapy with acceptance and commitment therapy (ACT) using exposure techniques on cognitive avoidance in female patients with generalized anxiety disorder.<br> <strong>Methods</strong>: A total of 10 women with generalized anxiety disorder were selected through purposeful sampling with Structured Clinical Interview for DSM Disorders (SCID-5). To determine the absence of personality disorder, Millon&rsquo;s clinical multiaxial inventory (MCMI-III) (Millon and Groosman, 2005) was used. Schema therapy was conducted for 20 weekly sessions and ACT with exposure techniques for 12 weeks and follow-up for 6 weeks. The cognitive avoidance questionnaire (CAQ) (Sexton and Douglas, 2004) was used as a pretest and posttest to follow up on the results. Analysis of variance with repeated measures was used to test the research hypotheses.<br> <strong>Results</strong>: The results showed that schema therapy is more effective than ACT in the subscales of thought suppression (F=12.80, P=0.037) and avoidance of threatening (F=25.61, P=0.015), but they have no significant statistical difference in other subscales and total score. Both treatments significantly reduced the total score of cognitive avoidance, but they lacked a statistically significant difference.<br> <strong>Conclusion</strong>: Schema therapy and ACT with exposure techniques are effective in reducing the severity of symptoms and improving cognitive avoidance in females with generalized anxiety disorder.
