Difficulties faced in life can affect marital relationships and such troubles may be dealt with in a multitude of ways, including coping religiously. The present study examined how religious coping, either in a positive or negative manner, may have an impact on marital satisfaction. Importantly, this association was studied dyadically in a sample of religiously diverse (Buddhists, 32.3%; Taoists, 17.6%; protestant Christians, 14.1%; and others who did not identify with a specific religion, 19.1%), married older Singaporean adults (N = 1928; 964 couples). Using actor-partner interdependence modeling, we found significant actor, partner, and combined actor-partner effects for positive and negative religious coping on marital satisfaction. Specifically, marital satisfaction was highest when both spouses reported high levels of positive religious coping and low levels of negative religious coping. Taken together, these findings suggest that it is the simultaneous act of either greater positive or lower negative religious coping by both spouses that is related to higher marital satisfaction.
