The purposes of this study were (a) to compare families with low ( n = 47) and high ( n = 44) levels of preseparation interparent conflict on mothers' report of paternal involvement (frequency, regularity, and length of visitation as well as regular payment of child support), children's adjustment, and mothers' level of stress; (b) to intercorrelate the four dimensions of paternal involvement; and (c) to relate the four dimensions of paternal involvement to children's age, children's gender, length of parental separation, children's adjustment, mothers' stress, paternal investment in the children, degree of environmental change, and children's level of interpersonal understanding. Children's mean age was 10.24 years, and parents had been separated a mean of 13.15 months. Compared to fathers in low-conflict families, fathers in high-conflict families visited less regularly and were less regular in their payment of child support. Mothers reported more adjustment problems for children in high-conflict families. All four dimensions of paternal involvement were intercorrelated only for high-conflict families. For both low- and high-conflict families, paternal involvement was related to paternal investment in the child but was unrelated to children's age, children's gender, and length of separation. Paternal involvement was most frequently related to children's adjustment in high-conflict families. For low-conflict families, paternal involvement was related low environmental change and children's well-developed interpersonal understanding skills.
