This study examined the behavioral, personality, and communicative predictors of acceptance and popularity in 608 early adolescents. Data were collected with sociometric methods and ratings in 30 sixth-grade classrooms. Hierarchical regressions were run to predict acceptance and popularity from prosocial, antisocial, and withdrawn behavior, agreeableness and extraversion, and pragmatic communicative skills. Low levels of antisocial behavior positively predicted peer acceptance. Popularity depended on a more complex profile of predictors. Prosocial and antisocial behavior contributed positively to popularity, whereas withdrawn behavior contributed negatively. Extraversion and pragmatic skills also played a role in the prediction of popularity. Extraversion moderated the associations of prosocial and antisocial behavior with popularity. Popularity was highest when high levels of prosocial or antisocial behavior were combined with high levels of extraversion. Pragmatic skills moderated the association of prosocial behavior with popularity. Popularity was highest when prosocial behavior and pragmatic skills were high.
