Insomnia, anxiety, and depression are common and co-morbid amongst college students. The mechanisms by which trait factors like intolerance of uncertainty and anxiety sensitivity connect to state anxiety and depression is unclear, but insomnia may mediate that relationship.
College students ( = 439) were recruited from national and local sources.
Participants completed the Sleep Condition Indicator (SCI), Depression, Anxiety and Stress Scale (DASS), Anxiety Sensitivity Index (ASI), and Intolerance of Uncertainty Scales (IUS).
All models predicted a significant amount of variability in state anxiety and depression ( between 0.24 and 0.32). Mediation analyses revealed that the relationship between anxiogenic and depressogenic traits and state anxiety and depression is significantly mediated by insomnia.
Our findings support the role of insomnia in the expression of anxiety and depression in at-risk college students. Clinical sleep intervention, either reactive or prophylactic, may help reduce mental health burden on campus.
失眠、焦虑和抑郁在大学生中很常见且常合并出现。不确定性不耐受和焦虑敏感性等特质因素与状态焦虑和抑郁之间的联系机制尚不清楚，但失眠可能介导这种关系。
从全国和地方招募了大学生（n = 439）。
参与者完成了睡眠状况指标（SCI）、抑郁、焦虑和压力量表（DASS）、焦虑敏感性指数（ASI）和不确定性不耐受量表（IUS）。
所有模型都预测了状态焦虑和抑郁的显著变异性（在0.24至0.32之间）。中介分析表明，致焦虑和致抑郁特质与状态焦虑和抑郁之间的关系由失眠显著介导。
我们的研究结果支持失眠在高危大学生焦虑和抑郁表达中的作用。反应性或预防性的临床睡眠干预可能有助于减轻校园心理健康负担。
