Objective: The aim of the present study was to determine the efficacy of acceptance and commitment therapy (ACT) compared to cognitive-behavioral therapy (CBT) on anger and interpersonal relationships among male students. Method: In the present study, several universities were selected from the public universities in Tehran province, based on random cluster sampling. Then, 400 students from selected universities were selected randomly and Aggression Questionnaire (AGQ) was administered on them. After collecting information, among the participants who gained scores higher than the average, 30 were selected based on the lottery and randomly (sorting their names in alphabetical order and randomly selecting them) and then were placed randomly in ACT (n = 15) and CBT (n = 15) groups. Also, the Fundamental Interpersonal Relation Orientation- Behavior (FIRO-B) and Aggression Questionnaire (AGQ) was performed on both groups before and after intervention. Results: The results indicated that at the end of treatment, there was a significant decrease in the degree of anger among the participants and a significant improvement in all subscales of interpersonal relationships. Also, a significant difference was found between the 2 groups of ACT and CBT in terms of anger changes. Considering that the anger changes in the ACT group were higher, it can be concluded that the ACT group had more changes than the CBT group, but there was no significant difference between the 2 groups of ACT and CBT in terms of FIRO-B subscales. Conclusion: In some cases, such as anger, ACT has a better effect than CBT, and in others, such as interpersonal problems, it is as effective as CBT

Objective: The present study evaluated the model of mediating variables concerning effectiveness of mindfulness in improving women's marital satisfaction. Method: This study was quasi-experimental with pre-test, post-test and control groups. The statistical population included every married woman in Tehran in the year 1396 (2017). The research sample was composed of 60 married women with moderate marital satisfaction. They were chosen using the convenient sampling technique and were randomly assigned to control and experimental groups. The experimental group attended 8 sessions of Mindfulness-Based Stress Reduction (MBSR) and the control group was on a waiting list. Both groups answered the Five Facet Mindfulness Questionnaire (FFMQ), the Depression, Anxiety, and Stress Scale (DASS), Difficulties in Emotion Regulation Scale (DERS), Interpersonal Reactivity Inventory (IRI), Needs for Intimacy Questionnaire of Bagarozi, Positive and Negative Affect Scale (PANAS) and the Couple Satisfaction Index (CSI) before and at end of intervention. The data were analyzed by Structural Equation Modeling (SEM) using PLS-22 and SPSS-23. Results: In the initial hypothetical model, which included the direct effect of mindfulness on marital satisfaction and its indirect effects through psychological distress, emotion regulation, empathy, marital intimacy and positive emotion on marital satisfaction, coefficients of all model paths were significant at 95% level except direct path of mindfulness to marital satisfaction (t = 1.14), marital intimacy to marital satisfaction (t = 0.48) and positive affection to marital satisfaction (t = 1.75). After removing the non-significant paths, the model was tested again and the model fit index (GOF = 0.47) was a very good fit for the modified overall model. Conclusion: The results identified mindfulness-based stress reduction intervention was effective in enhancing marital satisfaction through reducing psychological distress and improving emotion regulation and empathy.

Objective: The purpose of the present study was to evaluate the factor structure, validity, and reliability of the revised Relationship Obsessive-Compulsive Inventory (ROCI), with emphasis on Iranian culture. Method: The statistical sample consisted of 341 married students studying in Tehran universities in the academic year 2018-2019, who were selected by available sampling method. The New ROCI, Obsessive-Compulsive Inventory-Revised (OCI-R), Obsessive Beliefs Questionnaire (OBQ), Depression, Anxiety and Stress Scale (DASS), Dyadic Adjustment Scale (DAS), and Relationship beliefs inventory (RBI) were the tools of the present study. Results: The Content Validity Index (CVI) and Content Validity Ratio (CVR) of the new ROCI were good. Also, there was a significant and negative correlation between all subscales and the total score of the new ROCI with all subscales and the total score of the DAS, and there was also a significant positive correlation between the subscales and the total score of the new ROCI with the subscales and the total score of OBQ, OCI-R, RBI, and DASS. Also, the two factor model explained 54.50% of the variance in the new ROCI. Furthermore, all of the confirmatory factor analysis indices of the new ROCI were better than the original ROCI. The results of test-retest correlation of the factor one and two of ROCI were 0.85 and 0.78, respectively. Also, the Cronbach's alpha of the factor one and two of ROCI were 0.60 and 0.74, respectively. Conclusion: In general, it can be said that the new ROCI was different from the original ROCI, and the new ROCI had better indicators than the original ROCI.
