This study explores the relationship between residential, biological fathers' parental engagement, financial contributions, and psychological well-being in 2-parent families. Specifically, this study focuses on how fathers' parental engagement and financial contributions are related to their self-esteem, self-efficacy, and psychological distress. Analyses utilize data from the first 2 waves of the Panel Study of Income Dynamics' Child Development Supplement and employ a subsample of father-child pairs (N = 771). The most consistent finding was that fathers' engagement in parenting and financial contributions to the family predicted improvements in fathers' psychological well-being. On the other hand, the results found very limited support for the more common proposition that healthy psychological functioning promotes increases in fathers' parental engagement and financial contributions.
