Objective: The present study aimed to compare obsessive beliefs and pain severity between individuals undergoing Methadone Maintenance Treatment (MMT) and a control group of healthy individuals. Method: This research employed a descriptive-comparative design. The statistical population comprised individuals attending MMT centers in Shahroud in 2024 and their healthy counterparts. Using purposive and convenience sampling methods, 50 participants were selected for each group. Data collection instruments included the obsessive beliefs questionnaire and the brief pain inventory-short form. Data were analyzed using multivariate analysis of variance (MANOVA) and independent samples t-tests. Results: Results indicated that individuals undergoing MMT reported significantly higher levels of pain severity and obsessive beliefs, specifically regarding inflated responsibility for harm, perfectionism, and the importance/control of thoughts, compared to the control group. Conclusion: Based on these findings, obsessive beliefs and pain severity warrant greater clinical attention within MMT protocols. It is suggested that psychological interventions aimed at restructuring obsessive beliefs and reducing pain sensitivity be integrated into methadone maintenance programs.
