Interoception is the sense through which internal bodily changes are signalled and perceived. Individual differences in interoception are linked to emotional style and vulnerability to affective disorders. Here we test how experiential sleep quality relates to dimensions of interoceptive ability. 180 adults (42 'non-clinical' individuals, 138 patients accessing mental health services) rated their quality of sleep before performing tests of cardiac interoception. Poor sleep quality was associated with lower measures of interoceptive performance accuracy, and higher self-report measures of interoceptive sensibility in individuals with diagnoses of depression and/or anxiety. Additionally, poor sleep quality was associated with impaired metacognitive interoceptive awareness in patients with diagnoses of depression (alone or with anxiety). Thus, poor sleep quality, a common early expression of psychological disorder, impacts cardiac interoceptive ability and experience across diagnoses. Sleep disruption can contribute to the expression of affective psychopathology through effects on perceptual and interpretative dimensions of bodily awareness.
内感受是一种将身体内部变化进行信号传递和感知的感觉。内感受的个体差异与情绪风格以及情感障碍易感性相关。在此，我们测试了体验性睡眠质量与内感受能力各维度之间的关系。180名成年人（42名“非临床”个体，138名接受心理健康服务的患者）在进行心脏内感受测试前对自己的睡眠质量进行了评分。睡眠质量差与内感受表现准确性较低以及诊断为抑郁症和/或焦虑症个体的内感受敏感性自我报告较高相关。此外，睡眠质量差与诊断为抑郁症（单独或伴有焦虑症）患者的元认知内感受意识受损相关。因此，睡眠质量差作为心理障碍常见的早期表现，会影响不同诊断下的心脏内感受能力和体验。睡眠中断可通过对身体意识的感知和解释维度产生影响，从而促使情感精神病理学的表现。
