Abstract: (43 Views)
Introduction: Obsessive-compulsive personality disorder is one of the most common personality disorders that has a profound impact on the individual and social functioning of sufferers. The aim of this study was to compare the effectiveness of Metacognitive Interpersonal Therapy (MIT) and Acceptance and Commitment Therapy (ACT) in improving difficulties in emotion regulation and perfectionism in individuals with Obsessive-Compulsive Personality Disorder.
Methods: This research was conducted using a quasi-experimental method with a pre-test, post-test, and three-month follow-up design with a control group. The statistical population included individuals with obsessive-compulsive personality disorder who visited the counseling centers of Yazd in 2024. The sample consisted of 41 participants selected through convenience sampling and randomly assigned to three groups: MIT (n=13), ACT (n=14), and control (n=14). The experimental groups received interventions over 10 weekly sessions, while the control group received no treatment. The study instruments included the Difficulties in Emotion Regulation Scale (DERS) and Perfectionism Scale.
Results: The results of repeated measures analysis of variance showed that there was a significant difference between the post-test scores of emotion regulation difficulty (F=255/410, p<0/01) and perfectionism (F=356/950, p<0/01) of the three groups. Also, Bonferroni post-test showed that interpersonal metacognitive therapy was more effective than acceptance and commitment therapy in improving emotion regulation difficulty and reducing perfectionism.
Conclusion: MIT could be used as a more effective intervention compared to ACT for addressing emotional and cognitive challenges in individuals with obsessive-compulsive personality disorder.
