This multi-institutional sleep study involved two phases aimed at investigating sleep alterations in patients with any stage of breast and lung cancer. The first phase of this study used an 82-item, 20-minute telephone survey to elicit information regarding the impact of sleep disturbances on a convenience sample of 150 patients. Of these patients, 44% reported a sleep problem during the month before the interview. Significant relations included these: report of sleep problems prediagnosis over the past month (x = 5.82; p = 0.02), duration of sleep medication use and frequency of sleep problem (r = 0.58; p = 0.05), age and severity of sleep problems (r = 0.38; p = 0.05), and frequency and severity of the sleep problem over the past month (r = 0.21; p < 0.10). Communication with health care providers occurred in 16.6% of patients reporting a sleep disturbance. The second phase of this study explored the type, frequency, and severity of sleep problems and perceptions of causation, support, and methods of coping with the sleep problem. A qualitative approach to the problem was used in this phase. A one-time telephone interview of 42 patients, derived from a convenience sample, revealed a 45% prevalence of sleep problems a month before the interview. A qualitative analysis of the responses suggested that sleep problems are related to experiences of other symptoms and perceptions of cancer and treatment. Content analysis of the responses identified the following categories: figuring out the reason, seeking help, seeking support and relation to the overall cancer experience.
这项多机构睡眠研究包括两个阶段，旨在调查处于任何阶段的乳腺癌和肺癌患者的睡眠改变情况。该研究的第一阶段使用了一项包含82个项目、时长20分钟的电话调查，以获取有关睡眠障碍对150名患者便利样本影响的信息。在这些患者中，44%报告在访谈前一个月存在睡眠问题。显著关系包括：过去一个月诊断前睡眠问题的报告（x = 5.82；p = 0.02）、睡眠药物使用时长与睡眠问题频率（r = 0.58；p = 0.05）、年龄与睡眠问题严重程度（r = 0.38；p = 0.05），以及过去一个月睡眠问题的频率与严重程度（r = 0.21；p < 0.10）。在报告有睡眠障碍的患者中，16.6%与医疗服务提供者进行了沟通。该研究的第二阶段探讨了睡眠问题的类型、频率和严重程度，以及对病因、支持和应对睡眠问题方法的认知。此阶段采用了定性方法来研究该问题。对来自便利样本的42名患者进行的一次性电话访谈显示，在访谈前一个月睡眠问题的患病率为45%。对回答的定性分析表明，睡眠问题与其他症状的经历以及对癌症和治疗的认知有关。对回答的内容分析确定了以下类别：找出原因、寻求帮助、寻求支持以及与整体癌症经历的关系。
