This study examined divorced single-mothers` adjustment after divorce by nonresident fathers` participation in parenting after divorce and their coparental relationship. The data were collected from 160 divorced mothers who were divorced within last five years and were raising at least one minor child. According to the mothers` report, the nonresident fathers` involvement in parenting after divorce in terms of child support and visitation was very low. Variables that were related to divorced mothers` parental stress and adjustment after divorce were different. The variables of social support, work-to-family conflict, family-to-work conflict, and satisfaction with parenting circumstance including custody, child support, and nonresident father visitation were associated with divorced mothers` parental stress. However, the variables of the age of the youngest child, coparental conflict, and parental stress were related to divorced mothers` adjustment after divorce. The implications for public policy and service delivery were discussed.
