Abstract
The articles in this special issue are informed by the historic changes in the twentieth century (i.e., decreasing family size, changing family roles, and youth demonstrating more independent behaviors) that propelled intensive study of fathers' impacts on child development. The papers are conceptualized within a developmental systems framework and focused on a father's presence rather than on his absence in the family, going beyond the study of merely father involvement. Papers reflect longitudinal and cross-sectional methods and examine issues related to paternal mental health, parenting behavior, cultural context, and children's physical and mental health.
