--- - |2 This article explored the implications of diverse family structures on adolescents’ adjustment, with an emphasis on whether and, if so, how diverse family structures influence and predict developmental outcomes. Family relationships within the family unit are a stronger predictor of adolescents’ development than the particular family structure. Transitions in families that result in notable reductions in effective parenting practices and economic well‐being will negatively affect youth, regardless of family structure. Family processes that promote optimal growth and development among youth in traditional two‐parent, heterosexual households work similarly for those growing up in nontraditional family structures. A conceptual model to advance this field of research is offered, and implications for research and policy are discussed. - Journal of Research on Adolescence, Volume 28, Issue 3, Page 650-664, September 2018.
