Although children's contact with involved, committed, nonresidential fathers can improve social, emotional, cognitive, and academic outcomes, fathers have largely been absent from parenting interventions that overlook men's role as a critical parenting partner. This article details research showing that young incarcerated fathers' attitudes about--and communication and responsiveness to--their very young children improved following a brief psychoeducational intervention and describes a second pilot project with child-welfare--involved fathers and families. The projects enrolling high-risk, difficult-to-engage parents yielded promising findings, demonstrating how building interventions that are inclusive of fathers stands to benefit child outcomes.
