Objective: Marriage is the largest and most important event in an individual's life, and a healthy marriage necessitates several elements including intimacy, commitment, and satisfaction. The present study aims to explain the model of predicting marital commitment based on object relations with the mediating role of emotion regulation.Materials and Methods: The statistical population of this study included all married couples residing in the city of Qom in ۲۰۲۳, totaling ۷,۶۳۴ individuals. From this population, ۱۴۸ women and ۱۱۰ men were selected through purposive sampling. This research utilized a descriptive-correlational and structural equation modeling design. Participants completed the Marital Commitment Inventory (DCI) by Adams and Jones (۱۹۹۷), the Emotion Regulation Scale (ACS) by Williams et al. (۱۹۹۷), and the Object Relations Scale by Bell et al. (۱۹۹۵). Data analysis was conducted descriptively and inferentially using SPSS-۲۸ and AMOS-۲۴ software. The relationships between variables were analyzed using Pearson correlation and path analysis, and the mediating role was tested using the Sobel method.Findings: The findings of this study indicated that the mediating role of emotion regulation in the relationship between object relations and marital commitment was confirmed (p < .۰۵). The indirect effect of object relations on marital commitment was -۰.۳۱۹.Conclusion: The results showed that considering the complex reciprocal influence of topics emerging in couples' interactions and experiences, as well as the role of emotion regulation, can provide valuable insights into the factors that contribute to the success and longevity of relationships.
