Research in younger adults suggests sleep discrepancy (objective/subjective measurement difference) is a consistent pattern that primarily occurs within individuals with insomnia. To examine whether older adults exhibit a similar pattern, this study compared night-to-night inconsistency in sleep discrepancy between older adults with and without sleep complaints. Older adults (N = 103; mean age = 72.81, SD = 7.12) wore an Actiwatch-L® (24 hr per day) and concurrently completed sleep diaries for 14 days. Sleep discrepancy = diary (sleep onset latency [SOL] or wake [time] after sleep onset [WASO]) - actigraphy (SOL or WASO). Both groups exhibited sleep discrepancy, but complainers exhibited significantly more night-to-night variability. Sleep discrepancy was a variable behavior that was not limited to insomnia, but instead manifested by degree throughout our older sample. Greater attention to variability in sleep research and clinical practice is warranted.
研究表明，年轻人的睡眠差异（客观/主观测量差异）是一种普遍存在于失眠患者中的模式。为了研究老年人是否存在类似的模式，本研究比较了有睡眠抱怨和无睡眠抱怨的老年人之间睡眠差异的夜间不稳定性。老年人（N=103；平均年龄=72.81，标准差=7.12）佩戴 Actiwatch-L®（每天 24 小时）并同时完成了 14 天的睡眠日记。睡眠差异=日记（睡眠潜伏期[SOL]或睡眠后醒来时间[WASO]）-活动记录仪（SOL 或 WASO）。两组均表现出睡眠差异，但抱怨者的夜间不稳定性显著更高。睡眠差异是一种可变行为，不仅限于失眠，而是在我们的老年人样本中表现出不同程度。有必要在睡眠研究和临床实践中更加关注变异性。
