Previous studies have revealed that the ways couples deal with stress in their lives are significantly associated with their marital quality and overall marital functioning. However, there has been little empirical evidence linking dyadic coping with marital quality over time. This study addresses the relationship between dyadic coping and marital quality among 90 couples over a period of 2 years. The results reveal that dyadic coping was significantly associated with marital quality over 2 years. For women, both their own dyadic coping and that of their partner were significant predictors, whereas for men only their own dyadic coping was predictive. The results are discussed with regard to prevention of marital distress.
