Previous studies have established the role of various measures of cognitive functioning in dampening the association between adverse life events ('life stress') and adolescents' emotional and behavioural problems. However, it is not yet clear if general cognitive ability ('intelligence') is a protective factor. In this study of 1,175 10- to 19-year-olds in five secondary schools in England, we explored this issue. We found that even after controlling for sex, age, family poverty, and special educational needs, the association of life stress with emotional, hyperactivity, and conduct problems was significant. General cognitive ability moderated the association between life stress and conduct problems; among adolescents with higher than average general cognitive ability, the association between life stress and conduct problems was non-significant.
先前的研究已经确定了各种认知功能测量在减轻不良生活事件（“生活压力”）与青少年情绪和行为问题之间的关联方面的作用。然而，目前尚不清楚一般认知能力（“智力”）是否是一种保护因素。在这项对英格兰五所中学的 1175 名 10 至 19 岁青少年的研究中，我们探讨了这个问题。我们发现，即使在控制了性别、年龄、家庭贫困和特殊教育需求之后，生活压力与情绪、多动和行为问题之间的关联仍然显著。一般认知能力调节了生活压力与行为问题之间的关联；在一般认知能力高于平均水平的青少年中，生活压力与行为问题之间的关联不显著。
