虽然睡眠障碍在精神分裂症中很普遍，但尚不清楚睡眠障碍是否与受损的应对和感知生活质量唯一相关。我们同时评估了29名精神分裂症或情感性精神障碍患者急性期后的睡眠质量、症状和应对方式。评估工具包括匹兹堡睡眠质量指数、阳性和阴性症状量表、海因里希斯生活质量量表和应对方式量表。多元回归分析预测生活质量和应对睡眠质量控制的年龄和症状的严重程度。在一个由7名受试者组成的子集上，非优势手腕活动记录仪被用作他们自我报告的睡眠不佳的客观检查。分析显示，睡眠质量差预示着生活质量低（r = -0.493; p = 0.022），并且在面临压力时对采用积极重新评估的偏好降低（r = -0.0594; p = 0.0012）。活动记录仪证实了一部分受试者的睡眠质量较差。他们的睡眠时间较短（p <0.0005），平均睡眠次数较短（p <0.005），长时间觉醒次数较多（p < 0.05）。研究结果与以下假设一致：睡眠不佳可能在维持精神分裂症患者的生活质量和应对能力受损方面发挥独特作用。这些协会也可能适用于社区控制。
While sleep disturbance is widespread in schizophrenia it is less clear whether sleep disturbance is uniquely related to impaired coping and perceived quality of life. We simultaneously assessed sleep quality, symptoms, and coping in 29 persons with schizophrenia or schizoaffective disorder in a post acute phase of illness. Assessment instruments included the Pittsburgh Sleep Quality Index; the Positive and Negative Symptom Scale; the Heinrichs Quality of Life Scale; and the Ways of Coping Scale. Multiple regressions were performed predicting quality of life and coping from sleep quality controlling for age and symptom severity. On a subset of seven subjects non-dominant wrist actigraphy was used as an objective check of their self-reported poor sleep. Analyses revealed that poor sleep quality predicted low quality of life (r = -0.493; p = .022) and reduced preference for employing positive reappraisal when facing a stressor (r = -0.0594; p = 0.0012). Actigraphy confirmed poor sleep quality in a subset of subjects. They had shorter sleep duration (p < .0005), shorter average sleep episodes (p < .005) and more episodes of long awakening (p < 0.05) than community norms. The results are consistent with the hypotheses that poor sleep may play a unique role in sustaining poor quality of life and impaired coping in patients with schizophrenia. These associations may hold for community controls as well.
