Study title

This study had three goals. First, we examined the prevalence of the participant roles of bullying in middle adolescence and possible gender differences therein. Second, we examined the behavioral and status characteristics associated with the participant roles in middle adolescence. Third, we compared two sets of criteria for assigning students to the participant roles of bullying. A description of the selection of the participants can found in '2016_Pouwels_Participant Roles_read me.pdf'. We conducted the final analyses based on a sample of 1,638 adolescents (50.9% boys, Mage=16.38 years, SD=.80) who completed the shortened participant role questionnaire and peer nominations for peer status and behavioral characteristics.
