自我报告的习惯性睡眠时间是一个重要的变量，因为睡眠时间的短和长与死亡率有关。对这些结果的猜测通常集中在身体健康上，而不是心理因素上。我们调查了焦虑和抑郁在习惯性睡眠时间报告中的作用，方法是检查个人对睡眠时间的初始估计与两周内睡眠日记之间的相对和绝对差异。结果表明，抑郁情绪不仅与最初低估睡眠时间的倾向(相对差异)有关，而且还与无论方向如何夸大报告的睡眠时间(绝对差异)有关。这些结果意味着，检验报告睡眠时间和死亡率之间关系的研究应该考虑心理健康因素。
Self-reported habitual sleep time is an important variable because short and long sleep times are associated with mortality. Speculation with regard to these results usually focuses on physical health, rather than psychological factors. We investigated the role of anxiety and depression in reports of habitual sleep times by examining the relative and absolute discrepancy between individuals' initial estimates of their sleep times and sleep diaries made over a 2-week period. Results indicated that depressed mood was associated not only with a tendency initially to underestimate length of sleep (relative discrepancy), but also to exaggerate reported sleep time regardless of direction (absolute discrepancy). These results imply that studies that examine relationships between reported sleep times and mortality should take mental health factors into account.
