This paper reviews and critiques the growing literature on the distinction between reactive and proactive aggression in children and adolescents. Empirical findings suggest that the subtypes of aggression are (a) preceded by different familial precursors, (b) associated with different behavioral outcomes, (c) driven by different social-cognitive and emotional processes, and (d) related to different social experiences. Because measurement difficulties have been a prominent concern in the study of reactive and proactive aggression, a discussion of various assessment approaches is included. Suggestions are made for future research directions, including a greater use of observational and laboratory-based methods, more longitudinal designs, and a greater focus on the careful assessment of the subtypes of aggression.

This study explored the role of the classroom teacher in peers' evaluations of liking and disliking of their classmates. Teacher cognitions about children (teacher liking of students, teacher attributions for aggressive student behavior) and teacher behavior toward children (positive, corrective/negative) were examined as mediators in the link between children's own behavior (aggression, prosocial behavior) and peer liking and disliking. Participants were 127 second-graders in 12 classrooms (64 males, 63 females). Data on child behavior were collected through peer and teacher report, data on teacher cognitions about children were collected through self report, data on teacher behavior toward children were collected through naturalistic classroom observations, and data on peer liking and disliking were collected through peer nominations. Data were analyzed using path analysis. Results indicated that teacher cognitions about children and corrective/negative teacher behavior toward children mediated the relations between aggressive and prosocial child behavior and peer disliking.

The authors examined short-term temporal stability of reactive and proactive aggression, as well as short-term consistency of differential relations of reactive versus proactive aggression to 4 correlates. The authors used parent, teacher, peer, and self-report measures twice across 1 year to assess reactive aggression, proactive aggression, hyperactivity, social skills, anger expression, and depressive symptoms of 2nd-grade boys and girls (N = 57). Both subtypes of aggression remained stable across the year, even when the other subtype of aggression was explained at each assessment. Reactive aggression, but not proactive aggression, was consistently positively related to hyperactivity, poor social skills, and anger expression at each assessment.

The goals of the current study were to investigate whether peer rejection mediated the relation between aggression and depressive symptoms in childhood, and if so, whether this mediational pathway was specific to the reactive subtype of aggression. Participants were 57 second-grade children (22 girls and 35 boys). Data on reactive aggression, proactive aggression, depressive symptoms, and peer rejection were collected from four sources (parents, teachers, peers, and self ). Results revealed that reactive aggression, but not proactive aggression, was positively related to depressive symptoms. Furthermore, peer rejection partially mediated the relation between reactive aggression and depressive symptoms.We would like to thank the undergraduate research assistants who worked with us on this project. Most of all, though, we appreciate the help of the children, parents, teachers, and principals who made this project possible.
