Anxiety and depression are often highly correlated with each other. To explain this connection, the present study examined the longitudinal relationship between earlier anxiety and later depression, using avoidance as a mediator and trauma as a moderator. Participants (N=6504 adolescents) completed baseline measures of anxiety and depression, a measure of avoidance one year later, a measure of trauma six to eight years later, and a measure of depression 12-14 years later. Analyzed with structural equation models, the results showed that anxiety predicted later depression, and this relationship was partially mediated by avoidance. The relationship between avoidance and depression was not moderated by trauma. Together, these findings suggest that anxiety may influence later depression through avoidance, and this relationship remains unaffected by experiencing a traumatic experience.
焦虑和抑郁常常高度相关。为了解释这种关联，本研究通过回避作为中介，创伤作为调节因素，考察了早期焦虑与后期抑郁之间的纵向关系。参与者（N=6504 名青少年）在基线时完成了焦虑和抑郁的测量、一年后完成了回避的测量、六至八年后完成了创伤的测量、十二至十四年后完成了抑郁的测量。采用结构方程模型分析，结果表明，焦虑预测了后期抑郁，回避在其中起部分中介作用。回避和抑郁之间的关系不受创伤的调节。总的来说，这些发现表明，焦虑可能通过回避影响后期抑郁，而这种关系不受经历创伤事件的影响。
