These studies disentangle the relationships between wanting to nap (nap desire), actually napping (nap behavior), and depressed and anxious mood. Study 1 partially replicated and extended findings connecting napping and depressed and anxious mood. Study 2 explored the distinction between nap desire and behavior using a new, larger sample and a different technique.
Study 1 used a longitudinal, multimethod approach to understand napping and mood among undergraduate students in the United States ( = 104). In Study 2, a cross-sectional survey was conducted on adults over 25 in the continental United States ( = 1406), including items from the DASS-21 and questions about nap desire and behavior.
Study 1 found a significant relationship between same-day napping behavior and depressed mood ( = 1.61, = 0.08 vs. = 1.44, = 0.06, = .018) but not anxious mood ( = .766). Study 2 partially replicated those findings; Analysis of Covariance (ANCOVA) showed that napping desire had a significant effect on anxious ((1, 1291) = 6.86, = .009, partial η = .005) and depressed mood ((1, 1291) = 13.46, < .001, partial η = .010), accounting for age, gender, and restedness, but napping behavior did not add to that effect.
Wanting to nap is related to greater depressed and anxious mood, but actual napping did not add to that relationship. These results have implications for clinicians using sleep assessment as a screening tool for mental health and highlight the need for further research on napping motivation.
这些研究旨在理清想要小睡（小睡欲望）、实际小睡（小睡行为）与抑郁和焦虑情绪之间的关系。研究1部分重复并扩展了关于小睡与抑郁和焦虑情绪之间联系的研究结果。研究2使用新的更大样本和不同技术，探讨了小睡欲望与行为之间的区别。
研究1采用纵向、多方法的方法来了解美国本科生（n = 104）的小睡情况和情绪。在研究2中，对美国大陆25岁以上的成年人（n = 1406）进行了横断面调查，包括来自抑郁焦虑压力量表-21（DASS-21）的项目以及关于小睡欲望和行为的问题。
研究1发现当日小睡行为与抑郁情绪之间存在显著关系（β = 1.61，p = 0.08 对比 β = 1.44，p = 0.06，p = 0.018），但与焦虑情绪无关（p = 0.766）。研究2部分重复了这些结果；协方差分析（ANCOVA）表明，小睡欲望对焦虑情绪（F(1, 1291) = 6.86，p = 0.009，偏η² = 0.
