In-depth interviews with a Chicago sub-sample of both unwed fathers & mothers in the Fragile Families & Child Well-Being Study, conducted at six weeks & again at three months following the focal child's birth, builds upon subsequent survey analysis examining paternal involvement among unwed parents. Collectively, the findings form a conceptual framework for examining & facilitating paternal involvement & family development via the couple relationship context. Social work practice strategies, building upon a strengths-based perspective, are proposed with a focus on engaging an often overlooked & underserved member of the family in professional practice & advocacy-the unwed father. Findings are directed toward the development of promising social work interventions for children & families, while simultaneously advancing the aim of social work practice. 1 Appendix, 51 References.
