Negative peer status and relational victimization in children and adolescents: the role of stress physiology.

The purpose of the current investigation was to determine the unique associations between two subtypes of low peer status, peer rejection and unpopularity, and changes in relational victimization over time. This study also investigated if these associations were moderated by sympathetic nervous system (SNS) and parasympathetic nervous system (PNS) reactivity to peer stress. Sixty-one girls attending (M(age) = 11.91 years, SD = 1.62; predominantly Caucasian) a residential summer camp were followed across 1 calendar year. Participants' skin conductance and respiratory sinus arrhythmia were assessed during a laboratory stress protocol. Peer rejection and unpopularity were measured using peer nomination techniques and counselors reported on relational victimization. Both unpopularity and rejection were associated with increased relational victimization over time among girls who exhibited reciprocal SNS activation (i.e., high SNS reactivity coupled with PNS withdrawal). Rejection was also associated with subsequent victimization among girls exhibiting reciprocal PNS activation (i.e., low SNS reactivity, PNS activation). Findings underscore the biosocial interactions between low peer status and physiological reactivity in the prediction of peer maltreatment over time.
