The present study was conducted aimed at investigating the effectiveness of Miller’ s family relationship enrichment training in psychological well-being and marital violence from the perspective of abused women. The research method was semi-experimental (pre-test-post-test and follow-up with control group). The statistical population comprised all the couples who were victims of marital violence and referred to counseling centers in District 2 of Mashhad in Spring 2017. Of these couples, 30 were selected through convenience and purposeful sampling and were randomly assigned into two experimental (15 couples) and control (15 couples) groups. the experimental group received treatment for 8 sessions of a 90-minute weekly treatment, and the control group received no intervention during this period. to collect data, the Instrument for the Study of Marital Violence Scale (Strauss et al., 1996) and Reef's Psychological Well-being (1980) were employed. the research data was analyzed using the variance analysis with repeated measurements. the research findings demonstrated that Miller’ s family relationship enrichment training affects psychological well-being and marital violence from the perspective of abused women (P>0. 05). Also, the sustained effect of treatment was maintained after two months (p <0. 05). according to the research results, it can be concluded that with enriched relationships between couples, their psychological well-being will be improved from the perspective of abused women and as a result of this improvement, marital violence of their spouses will decrease.
