Increases in stress, symptoms of anxiety and depression, and sleep problems have been reported during the Covid-19 pandemic, and people with chronic medical conditions such as heart failure (HF) are especially vulnerable. The purpose of this study was to examine the extent to which sleep characteristics, sleep-related cognitions, anxiety, depression, perceived stress, and changes in these phenomena over time predict ways of coping with pandemic-related stress among participants in the HeartSleep study, a randomized controlled trial of the effects of cognitive behavioural therapy for insomnia (CBT-I) in people with HF.
Participants completed questionnaires to elicit sleep characteristics, daytime symptoms, mood and stress at baseline, 6 months after the intervention and during the Covid-19 pandemic. We added measures of coping during the pandemic (June-August 2020). The sample included 112 participants (M age = 63 ± 12.9 years; 47% women; 13% Black; 68% NY Heart Class II or III). Participants (43%) reported pandemic-related stressors and most often used secondary control coping. Insomnia severity, anxiety, depression, perceived stress, and sleep-related cognitions predicted secondary control coping (positive thinking, cognitive restructuring, acceptance, distraction), involuntary engagement (physiological arousal, rumination), and involuntary disengagement (emotional numbing).
Insomnia and mood disturbance are important determinants of coping and responses to stress. Improving sleep and symptoms among people with HF may improve coping during stressful events, and CBT-I may have protective effects.

在新冠疫情期间,人们报告压力增加、焦虑和抑郁症状以及睡眠问题,而患有慢性疾病(如心力衰竭)的人尤其容易受到影响。本研究的目的是检查睡眠特征、与睡眠相关的认知、焦虑、抑郁、感知压力以及这些现象随时间的变化在多大程度上预测 HeartSleep 研究参与者应对与大流行相关的压力的方式,这是一项关于认知行为疗法治疗失眠(CBT-I)对心力衰竭患者影响的随机对照试验。
参与者在基线、干预后 6 个月和新冠疫情期间完成了问卷调查,以了解睡眠特征、白天症状、情绪和压力。我们在 2020 年 6 月至 8 月期间增加了应对大流行的措施。样本包括 112 名参与者(M 年龄=63±12.9 岁;47%为女性;13%为黑人;68%为纽约心脏协会心功能 II 或 III 级)。43%的参与者报告了与大流行相关的压力源,大多数人使用二级控制应对。失眠严重程度、焦虑、抑郁、感知压力和与睡眠相关的认知预测了二级控制应对(积极思考、认知重构、接受、分心)、非自愿参与(生理唤醒、沉思)和非自愿退出(情感麻木)。
失眠和情绪障碍是应对和对压力反应的重要决定因素。改善心力衰竭患者的睡眠和症状可能会改善他们在紧张事件中的应对能力,CBT-I 可能具有保护作用。
