Sleep disturbances are associated with poor health outcomes in older adults. The Patient-Reported Outcomes Information System (PROMIS) Sleep Disturbance Scale was designed to assess self-reported general sleep and sleep disturbance. The objective of this study was to validate the short-form PROMIS Sleep Disturbance Scale for use among older adults living in independent-living and continuing care retirement communities.
Older adults (N = 307) were recruited from retirement communities in San Diego, CA, to participate in a physical activity intervention. Study participants were on average 83.6 years (SD 6.4) and predominately female (72.3%). Self-reported health outcomes included sleep disturbance, depressive symptoms, quality of life, stress, and pain. Internal consistency of the PROMIS Sleep Disturbance Scale was determined using Cronbach α, individual item means, and interitem correlations. Construct validity was examined using exploratory factor analysis techniques. Adjusted linear regression models assessed the predictive validity of the Sleep Disturbance Scale and associations with health outcomes.
The PROMIS Sleep Disturbance Scale had a Cronbach α = .856 and an interitem correlation of .504. All items loaded on 1 sole factor. Additionally, the sleep scale was significantly predictive of depressive symptoms, stress, and quality of life at 12 months.
The PROMIS 6-item Sleep Disturbance Scale had acceptable internal consistency and strong construct validity among a sample of elderly older adults in an independent-living community setting. These findings suggest that the PROMIS scale may provide an accurate assessment of sleep disturbance in older adults. Additional validation testing using objective measures of sleep is needed to confirm these findings further.
睡眠障碍与老年人健康状况不佳有关。患者报告的结局信息系统（PROMIS）睡眠障碍量表旨在评估自我报告的一般睡眠和睡眠障碍。本研究的目的是验证短式 PROMIS 睡眠障碍量表在独立生活和持续护理退休社区的老年人中的使用。
从加利福尼亚州圣地亚哥的退休社区招募老年人（N=307）参加一项体育活动干预。研究参与者的平均年龄为 83.6 岁（标准差 6.4），主要为女性（72.3%）。自我报告的健康结果包括睡眠障碍、抑郁症状、生活质量、压力和疼痛。使用 Cronbach α、个体项目均值和项目间相关性来确定 PROMIS 睡眠障碍量表的内部一致性。使用探索性因子分析技术检验结构效度。调整线性回归模型评估睡眠障碍量表的预测效度及其与健康结果的关联。
PROMIS 睡眠障碍量表的 Cronbach α 为.856，项目间相关性为.504。所有项目都加载在 1 个单一因子上。此外，睡眠量表在 12 个月时对抑郁症状、压力和生活质量具有显著的预测性。
在独立生活社区环境中，PROMIS 6 项睡眠障碍量表在老年人群体中具有可接受的内部一致性和较强的结构效度。这些发现表明，PROMIS 量表可能为老年人的睡眠障碍提供准确的评估。需要使用客观的睡眠测量方法进一步验证这些发现。
