Childhood Social Functioning and Young Adult Intimate Partner Violence in Girls With and Without ADHD: Response Inhibition as a Moderator

Objective: Examine the moderating effects of response inhibition on the longitudinal association between social preference/relational aggression measured in childhood, and intimate partner violence (IPV) measured in young adulthood, among women with (n = 140) and without (n = 88) histories of childhood ADHD. Method: During childhood, social preference was measured through confidential peer sociometric nominations, yielding negative and positive peer regard; relational aggression was assessed via staff behavioral observations; and response inhibition was assessed using commission errors from the continuous performance task. During young adulthood, IPV was ascertained via a clinician-administered, semistructured interview. Results: Social preference and relational aggression independently predicted IPV; this prospective link was moderated by response inhibition. Conclusion: In combination with low social preference or high relational aggression in childhood, poor response inhibition predicted the highest levels of young-adult IPV. Given the developmental significance of peer relationships, additional research on the causes of and treatments for poor social functioning in ADHD is warranted.
