Abstract
Fathers play a critical yet underappreciated role in adolescent development. To examine contributions of fathers’ parenting to attachment in adolescence and adulthood, this longitudinal study followed 184 adolescents from ages 13–24. At age 13, adolescents reported on their fathers’ parenting behavior and were observed in a father–teen conflict task; at ages 14 and 24, they completed the Adult Attachment Interview. Adolescents who lived with their father showed higher attachment security at age 14 (Cohen’s d = .72), compared to those with non-residential fathers. Fathers’ positive relatedness and support for teens’ psychological autonomy predicted attachment security at age 14. Fathers’ physical aggression predicted attachment insecurity in adolescence, whereas fathers’ verbal aggression predicted insecurity in adulthood, illuminating developmental shifts. Pathways to security were moderated by father residential status, adolescent gender, and race. Findings underscore the importance of fathers’ presence, autonomy support, and non-aggression in predicting adolescents’ state of mind in close relationships.
