Background: Marital infidelity is a traumatic experience that can lead to marital distress, attachment insecurity, and impaired post-traumatic growth. Although interventions such as Rational-Emotional Behavior Therapy (REBT) and Mentalization-Based Training (MBT) have been effective in reducing psychological problems, the comparative effectiveness of these two approaches on the mentioned variables in women affected by infidelity has been less explored.
Aims: This study aimed to compare the efficacy of Mentalization-Based Training and Rational-Emotional Behavior Therapy on marital distress, attachment behavior, and post-traumatic growth in women affected by marital infidelity.
Methods: The present study employed a quasi-experimental design with a pretest-posttest control group. The statistical population included all women who experienced marital infidelity in Tehran in 2023. Using convenience sampling, 45 participants were selected and assigned to two experimental groups and one control group (15 per group). Data collection tools included the Marital Distress Questionnaire (Weissman et al., 2009), the Attachment Behavior Questionnaire (Sandberg et al., 2012), and the Post-Traumatic Growth Inventory (Tedeschi & Calhoun, 1996). Data analysis was performed using SPSS-27 and multivariate analysis of covariance (MANCOVA).
Results: The results indicated that both therapeutic interventions had a significant effect on marital distress, attachment behavior, and post-traumatic growth in women affected by infidelity (P< 0.05). Furthermore, the comparison revealed that REBT was more effective than MBT in improving marital distress and attachment behavior (P< 0.05), whereas MBT was more effective than REBT in enhancing post-traumatic growth (P< 0.05).
Conclusion: The findings of this study can be utilized in counseling and therapy centers to support women affected by marital infidelity in addressing marital distress, attachment behavior, and post-traumatic growth. Additionally, conducting workshops to enhance the skills of psychologists and counselors is recommended.
