压力已被证明与抑郁症风险有因果关系。我们调查了认知能力作为压力生活事件对抑郁症状影响的调节因素的作用，以及这种作用是否因性别而异。对两个青少年数据集进行了分析：一个是 11-12 岁的代表性社区样本 (n = 460)，另一个是 9-17 岁的抑郁症家族风险增加样本 (n = 335)。在这两个数据集中，发现了三向相互作用，即对于女孩而言，较高的认知能力缓冲了压力与更严重的抑郁症状之间的关联，而男孩则不然。当结果被诊断为重度抑郁症时，这种相互作用就会被重复。女孩的这种缓冲效应不能归因于应对功效。然而，一小部分差异是由对环境压力因素的敏感性造成的。结果表明，女孩认知能力的这种调节作用很大程度上归因于认知操作有更多可用资源，这些资源可以防止压力引起的认知处理和认知控制减少，从而降低抑郁症状的可能性。
Stress has been shown to have a causal effect on risk for depression. We investigated the role of cognitive ability as a moderator of the effect of stressful life events on depressive symptoms and whether this varied by gender. Data were analyzed in two adolescent data sets: one representative community sample aged 11–12 years (n = 460) and one at increased familial risk of depression aged 9–17 years (n = 335). In both data sets, a three-way interaction was found whereby for girls, but not boys, higher cognitive ability buffered the association between stress and greater depressive symptoms. The interaction was replicated when the outcome was a diagnosis of major depressive disorder. This buffering effect in girls was not attributable to coping efficacy. However, a small proportion of the variance was accounted for by sensitivity to environmental stressors. Results suggest that this moderating effect of cognitive ability in girls is largely attributable to greater available resources for cognitive operations that offer protection against stress-induced reductions in cognitive processing and cognitive control which in turn reduces the likelihood of depressive symptomatology.
