There is limited understanding of the relation between insomnia and aspects of eating among college students though available data suggest salient clinical relationships. The present study explored a potential transdiagnostic mechanism in the relation between insomnia symptoms and eating expectancies. Participants were a racially/ethnically diverse sample of 1589 college students (80.4% females; Mage = 22.2 years, SD = 5.27) from an urban university. Primary analysis included three regression-based models of eating expectancies. Insomnia symptoms served as the predictor, and emotion dysregulation served as the indirect (mediator) variable in all models. Results indicated that insomnia symptoms yielded a significant indirect effect through emotion dysregulation on expectancies of eating to help manage negative affect, alleviate boredom, and lead to feeling out of control. Students experiencing insomnia symptoms may be at higher risk for experiencing dysregulated emotions and consequently maladaptive eating expectancies compared to good sleepers.
尽管现有数据表明失眠与大学生饮食方面存在显著的临床关联，但对于两者之间的关系，人们的了解十分有限。本研究旨在探索失眠症状与饮食预期之间关系的潜在跨诊断机制。参与者为来自一所城市大学的 1589 名种族/民族多样化的大学生（80.4%为女性；平均年龄为 22.2 岁，标准差为 5.27）。主要分析包括三个基于回归的饮食预期模型。在所有模型中，失眠症状作为预测因子，情绪调节作为间接（中介）变量。结果表明，失眠症状通过情绪调节对饮食期望产生显著的间接影响，这些期望有助于管理负面情绪、缓解无聊感，并导致失控感。与睡眠良好的学生相比，失眠症状患者可能更易出现情绪失调，继而产生不良的饮食预期。
