Research has yet to examine the social influences of parents, peers, and partners on bullying. This study explored the impact of social relationships on bullies, victims, bully/victims, and uninvolved participants. A sample of 370 college-age participants was asked about bullying, family environment, friends’ illegal behavior, and conflict resolution tactics in romantic relationships. Results indicated controls came from more secure and engaged families. Bully/victims reported friends engaging in more illegal behaviors than victims and uninvolved participants. Bullies and bully/victims reported more psychological coercion from their romantic partner. A logistic regression revealed peer illegal behaviors, psychological aggression, physical assault, and sexual coercion in romantic relationships best predicted bullies from non-bullies (67.3%). Based on these results, the interpersonal world of those involved with bullying significantly impacts behaviors.
