Past research suggests that exposure to parent psychological control and peer relational aggression and victimization experienced during adolescence is associated with relational intimate partner violence (IPV) in young adults (ages 22 to 29). However, the effects of continuities in these concerns across young adulthood have not been assessed. Relational IPV is characterized by behaviors intended to damage partner's emotional well-being and security in a romantic relationship (e.g., threatening to break up, purposefully ignoring, or causing jealousy). Six waves of data were collected biennially across 10 years from 662 participants (342 females) who were 12 to 18 years old in 2003. The 334 youth who were in a current romantic relationship at the sixth wave (T6, 10 years later) are the focus of this research. Tests of hypothesized structural equation models indicated that adolescent experiences of psychological control with fathers (but not mothers) predicted relational IPV at T6, but this association was no longer significant after accounting for continuity in father psychological control in young adulthood. Adolescent experiences of relational aggression and victimization with peers also predicted relational IPV at T6. This association remained significant for males, only, after continuity in experiences of relational aggression and victimization with peers in young adulthood was included in the model. Implications for the prevention of relational IPV in adolescence and young adults are discussed.
