The purpose of the current study is to examine how seminary student couples’ perceptions of family of origin and coping behaviors are related to their marital adjustment. With a hundred pairs of married seminary student couples completed a packet of surveys of the Family of Origin Scale (FOS), the Conflict Coping Behaviors Scale, and the Revised Dyadic Adjustment Scale (RDAS). A t–test, a correlation analysis, a regression analysis were performed to investigate the effects family of origin and coping behaviors on marital adjustment. The results indicated that a) the higher levels of the marital adjustment was positively correlated with the perceived healthy relationships in their family of origin, b) the higher levels of the marital adjustment was positively correlated with using rational coping behaviors, c) the lower levels of marital adjustments was positively correlated with avoidance coping behaviors. These results suggested that teaching management behaviors such as rational coping behaviors can be helpful for married seminary couples for their marital adjustment and have clinical implications for marriage counselors and marriage educators.
