Sleep disturbances are common in bipolar disorder (BD) and are often assessed by self-report at clinic visits over the course of BD treatment. Self-report may be subject to recall bias based upon current mood/affect states. This study sought to identify the degree of inaccuracy between subjective and objective measures of sleep duration in those with and without BD, and to assess the demographic and clinical correlates of this inaccuracy.
Thirty-one individuals with BD and 54 healthy control (HC) participants reported on the number of hours slept a night over the past month and subsequently completed up to 14 days/nights of wrist actigraphy which provided an objective measure of sleep duration. We compared the subjective rating to the average of all nights of objective sleep duration, and correlated the magnitude of inaccuracy with demographic and clinical characteristics in the BD and HC groups.
On average, both BD and HC groups overestimated their sleep, and there were no differences in inaccuracy between groups. In the BD group, greater inaccuracy was associated with lower functioning, even after controlling individually for objective and subjective sleep measures.
Cross-sectional study, only focus on sleep duration, and less severe bipolar symptoms of sample.
Inaccuracy in reports of sleep duration was associated with lower functioning among BD patients. Better identifying discrepancies in reports of sleep duration in clinical practice could help in more efficient monitoring and management of BD symptoms.
睡眠障碍在双相情感障碍（BD）中很常见，并且在 BD 治疗过程中通常会在就诊时通过自我报告来评估。自我报告可能会受到当前情绪/情感状态的回忆偏差的影响。本研究旨在确定 BD 患者和健康对照组（HC）中主观和客观睡眠时间测量之间的不准确程度，并评估这种不准确的人口统计学和临床相关性。
31 名 BD 患者和 54 名健康对照者报告了过去一个月每晚的睡眠时间，随后完成了多达 14 天/夜的腕部活动记录仪记录，该记录仪提供了客观的睡眠持续时间测量。我们将主观评分与客观睡眠持续时间的所有夜间平均值进行比较，并在 BD 和 HC 组中，将不准确的程度与人口统计学和临床特征相关联。
平均而言，BD 和 HC 组都高估了自己的睡眠时间，而且两组之间的不准确程度没有差异。在 BD 组中，即使在单独控制客观和主观睡眠测量后，功能下降程度与更大的不准确程度相关。
横断面研究，仅关注睡眠持续时间，且样本中双相情感障碍的症状较轻。
在 BD 患者中，报告的睡眠持续时间不准确与功能下降有关。在临床实践中更好地识别睡眠持续时间报告中的差异，可能有助于更有效地监测和管理 BD 症状。
