Sleep and mental health are intrinsically intertwined, but not every individual with problems sleeping develops a mental health disorder. This study examined the association among chronotypes, resilience, sleep quality and mental health symptoms amongst otherwise healthy individuals. Two hundred adults (M = 27.75 ± 5.11, 68% female) with no previous diagnosis of mental illness were recruited and filled in a set of questionnaires measuring chronotypes, sleep quality, depression and anxiety symptoms. The findings from the path analysis showed that the morning type had a statistically significant direct effect on a range of sleep quality indices. These included better subjective sleep quality, shortened sleep latency, and fewer daytime dysfunctions, as well as a higher level of resilience. However, it did not significantly affect depression and anxiety symptoms. In addition, the morning type had statistically significant indirect effects on a higher level of resilience and fewer depression and anxiety symptoms through the mediating effect of sleep quality indices. Findings from this study support that morning type is associated with better resilience and psychological health, which is mediated through better sleep quality.
睡眠与心理健康有着内在的紧密联系，但并非每个睡眠有问题的人都会患上心理健康障碍。本研究调查了健康个体的生物钟类型、心理韧性、睡眠质量和心理健康症状之间的关联。招募了200名未曾被诊断出患有精神疾病的成年人（平均年龄M = 27.75 ± 5.11岁，68%为女性），他们填写了一系列测量生物钟类型、睡眠质量、抑郁和焦虑症状的问卷。路径分析的结果表明，早起型对一系列睡眠质量指标有统计学上的显著直接影响。这些指标包括更好的主观睡眠质量、缩短的入睡潜伏期、更少的日间功能障碍以及更高水平的心理韧性。然而，它对抑郁和焦虑症状没有显著影响。此外，早起型通过睡眠质量指标的中介作用，对更高水平的心理韧性以及更少的抑郁和焦虑症状有统计学上的显著间接影响。本研究结果支持早起型与更好的心理韧性和心理健康相关，这是通过更好的睡眠质量介导的。
