Temperament, ADHD and peer relations among schoolchildren: the mediating role of school bullying.

The goal of the study is to investigate the link between temperament, attention-deficit hyperactivity disorder (ADHD) symptoms, social preference, bullying and victimization. The study sample consisted of 195 children attending the fourth and fifth grade (age 8-10), their mothers and their teachers. A multiinformant approach was used: mothers were interviewed about the temperament of their children; teachers were asked about ADHD symptoms; children responded to a peer nominations inventory designed to investigate their roles as bullies and/or victims and their social preferences (liked and disliked peers). A Structural Equation Model multigroup analysis (males and females) was used to test the relationships among variables hypothesized by the authors. The analysis showed that temperamental variables have a direct relation to ADHD symptoms, that ADHD has a direct relation to bullying behavior in males and to victimization in females and that bullies and victims are less well accepted than peers who belong to neither category. ADHD has only an indirect relation to social preference through the mediating role of school bullying. Copyright 2008 Wiley-Liss, Inc.
