Disruptive behaviour disorders are much more common in boys than girls (Office of National Statistics, 1999); in contrast, gender differences in normative problem behaviours are poorly understood. To address this issue, 228 6-year-olds (134 boys, 94 girls) were each observed playing a board game with a same-gender friend. Ratings of aggression, disruption, arousal and negativity were used to index problem behaviours. Multiple-groups confirmatory factor analyses demonstrated that the latent factor had the same metric for boys and girls, but a mean that was approximately half a standard deviation higher for boys than girls. In addition, the association between the latent factor and teachers' ratings of total difficulties was significantly stronger for boys than girls.
破坏性行为障碍在男孩中比女孩更为常见（国家统计局，1999 年）；相比之下，规范问题行为中的性别差异则知之甚少。为了解决这个问题，观察了 228 名 6 岁儿童（134 名男孩，94 名女孩）与同性朋友一起玩棋盘游戏。使用攻击性、破坏性、觉醒和消极性的评分来表示问题行为。多群组验证性因子分析表明，潜在因子在男孩和女孩中的度量相同，但男孩的平均值比女孩高约半个标准差。此外，潜在因子与教师对总困难程度的评价之间的关联在男孩中比女孩更为显著。
