Reactivity to exclusion prospectively predicts social anxiety symptoms in young adults.

Peer victimization leads to negative outcomes such as increased anxiety and depression. The prospective relationship between peer victimization and social anxiety in children and adolescents is well established, and adults with social anxiety disorder (SAD) are more likely than individuals with other anxiety disorders to report a history of teasing. However, a crucial bridge between these findings (peer victimization in young adults) is missing. We manipulated perceptions of peer exclusion in a young adult sample (N=108) using the Cyberball Ostracism Task. Reactivity to exclusion prospectively predicted social anxiety symptoms at a 2-month follow-up, whereas self-reported teasing during high school and current relational victimization did not. This research suggests that reactions to peer victimization may be a worthwhile target for clinical interventions in young adults. Targeting how young adults react to stressful social interactions such as exclusion may help prevent the development of SAD. Future research should test if reactivity to exclusion plays a role in the relationship between other disorders (e.g., depression) and peer victimization.
