Although childhood violence by any person is negative for children, little is known about whether violence by different family members is linked differently to problems in young adulthood, as family relationships might play different roles in children’s individual development. In this study, we examine parent and sibling violence and associations with emotional and behavioral problems, directly and indirectly via peer victimization. We used retrospective reports from 347 young adults (aged 20–24) who all reported childhood family physical violence, and we performed a path analysis using Mplus. The results showed that participants who had been victimized by a sibling only or by both a sibling and parent were more likely to report peer victimization than were participants who had been victimized by parents only. Peer victimization was, in turn, linked to more aggres- sion, criminality, and anxiety. Theoretical and clinical implications of these results are discussed.
