Fatigue is a prominent symptom of Generalized Anxiety Disorder (GAD). However, the pathways contributing to elevated fatigue in GAD are poorly understood. Sleep disturbance, also prominent in GAD, only partially explains elevated fatigue in GAD. Repetitive negative thinking (RNT) is a cognitive feature of both GAD and sleep disturbance, and RNT has recently also been associated with elevated fatigue. Therefore, this study assessed whether elevated fatigue in GAD is accounted for by a combination of sleep quality and RNT.

广泛性焦虑症女性反复消极思维、睡眠障碍和主观疲劳的关系

疲劳是广泛性焦虑症（GAD）的一个突出症状。然而，导致 GAD 疲劳升高的途径知之甚少。睡眠障碍（在 GAD 中也很突出）仅部分解释了 GAD 中的疲劳升高。重复消极思维 (RNT) 是 GAD 和睡眠障碍的认知特征，最近 RNT 也与疲劳升高有关。因此，本研究评估了睡眠质量和 RNT 是否可以解释 GAD 中的疲劳增加。
