Abstract
Introduction: Obsessive-compulsive relationship disorder (ROCD) is a type of obsessive-compulsive disorder characterized by obsessions and compulsions regarding intimate relationships. The present study examines the mediating role of mentalization as an important psychological mechanism in the relationship between attachment styles and symptoms of OCD.
Method: This descriptive-correlational study was conducted using a convenience sampling method on 281 married couples in Tehran. Participants completed attachment styles questionnaires, the Mentalization Scale, and the Partner-Related Obsessive-Compulsive Symptoms Questionnaire (PROCSI). Data were analyzed using Pearson correlation coefficient and structural equation modeling.
Findings: The results showed that insecure attachment styles (avoidant and anxious) were positively and significantly correlated with lower scores of mentalization and higher scores of symptoms of OCD, while secure attachment style was negatively and significantly correlated with higher scores of mentalization and lower scores of symptoms of OCD. Structural equation modeling analysis indicated that mentalization significantly mediates the relationship between attachment styles and OCD. In other words, insecure attachment styles lead to increased symptoms of OCD by reducing the capacity for mentalization. Conclusion: The findings of this study highlight the key role of mentalization as a psychological mechanism in the relationship between insecure attachment styles and traumatic childhood experiences with increased symptoms of OCD. These results emphasize the importance of assessing and strengthening mentalizing capacity, along with addressing attachment patterns and trauma history, in therapeutic interventions for couples with obsessive-compulsive disorder.
