The authors tested whether dimensions of negative affect--specifically, trait levels of negative emotionality and state levels of depressive symptoms--increased risk for substance abuse onset and whether perceived social support moderated this relation using data from a 5-year prospective study of 496 school-recruited adolescent girls. Initial negative emotionality, but not depressive symptoms, and deficits in parental, but not peer, support predicted future substance abuse onset in a multivariate hazard model. Tests of the interaction between negative affect dimensions and social support suggested that support did not moderate the relation of negative affect to risk for substance abuse onset. Results provide prospective support for the etiological role in the onset of substance abuse of trait-linked negative affect and of parental support.
作者利用对496名从学校招募的青春期女孩进行的为期5年的前瞻性研究数据，测试了消极情绪维度——具体而言，消极情绪的特质水平和抑郁症状的状态水平——是否会增加药物滥用开始的风险，以及感知到的社会支持是否会调节这种关系。在一个多变量风险模型中，初始消极情绪而非抑郁症状，以及父母支持的不足而非同伴支持的不足，预测了未来药物滥用的开始。对消极情绪维度与社会支持之间相互作用的测试表明，支持并没有调节消极情绪与药物滥用开始风险之间的关系。研究结果为特质相关消极情绪和父母支持在药物滥用开始中的病因学作用提供了前瞻性支持。
