Objective: Recently, stability of marriages and proper communication between couples has become more difficult. Therefore, exploring the impacts of relevant clinical interventions in resolving marital conflicts seems pivotal. The study aimed at investigating the effectiveness of object relations couple therapy on marital intimacy of divorce applicant couples with high-level borderline personality organization considering the moderating role of executive functioning. Method: Using a semi-experimental design, a sample consisting of 90 persons among all couples seeking a divorce, referred to counseling centers in Tehran, were selected voluntarily. All participants were screened by STIPO. Also, a final sample of 38 individuals with high-level personality organization was selected and randomly divided into control and experimental groups. After dropping the sample, 11 couples remained in the experimental group and 8 couples remained in the control group. Participants in the experimental group received 14 sessions of object relations couple therapy, while the control group remained on the waiting list. The Wisconsin Card Classification Test and Thomson & Walker Marital Intimacy Scale were administered on pre and post-intervention occasions as well. Data were analyzed by a multivariate analysis of covariance. Results: Significant positive effects were found for marital intimacy in the post-intervention stage (P<0.001). Significantly, better results were also evident for couples with higher executive function scores (P<0.001). Conclusion: It could be concluded that object relation couple therapy could promote the marital intimacy of couples with high-level borderline personality organization, and executive functioning could moderate the therapeutic effects.
