This study examined children's peer relations in relation to gender, symptoms of attention-deficit/hyperactivity disorder (ADHD), associated behaviour problems, prosociality, and self-perceptions, in a community sample. Six hundred and thirty-five 12-year-old children (314 girls) provided peer nominations and rated feelings of loneliness and self-perceptions regarding global self-worth and behavioural conduct. We obtained teacher ratings of ADHD symptoms, conduct and internalising problems, and prosociality. ADHD symptoms, conduct problems, internalising problems, and low levels of prosociality were all related to higher levels of peer dislike. Despite ADHD symptoms being related to more peer dislike, children with high levels of ADHD symptoms did not report more feelings of loneliness. The self-perceptions of children with high levels of ADHD were not related to peer dislike. Although high levels of ADHD symptoms were not related to peer dislike in girls, peers tolerated higher levels of ADHD symptoms among boys than among girls, providing support for the "gender appropriateness hypothesis'' regarding the impact and influence of ADHD symptomatology upon the peer relations of children within a community sample.
