The present study used data from the Minnesota Longitudinal Study of Risk and Adaptation to (a) investigate prospective associations between childhood experiences of abuse and neglect and multiple parenting outcomes in adulthood, and (b) evaluate the degree to which adult romantic functioning mediates these associations. Information regarding childhood abuse and neglect was gathered prospectively from birth through to age 17.5 years. Multimethod assessments of romantic functioning were collected repeatedly throughout early adulthood (ages 20 to 32 years), and parenting quality was assessed as participants assumed a parenting role (ages 21 to 38 years). Childhood abuse and neglect experiences predicted less supportive parenting (observed and interview rated) and higher likelihood of self-reported Child Protective Services involvement. The association with interview-rated supportive parenting was partially mediated by lower romantic competence, whereas the association with Child Protective Services involvement was partially mediated by more relational violence in adult romantic relationships.
