Adequate and sufficient sleep is essential for good health, effective functioning, and well-being, yet recent trends show increasing sleep deprivation, especially among adolescents and young adults. General procrastination and bedtime procrastination understood as the tendency to delay going to bed without external pressure, may contribute to sleep deprivation and fatigue. This study investigated how individual differences in time perspective are related to sleep sufficiency and daytime fatigue, two different sleep outcomes. For these relationships, the possible role of an intermediate pathway leading through general procrastination and then through bedtime procrastination was also examined. Zimbardo Time Perspective Inventory, Irrational Procrastination Scale, Bedtime Procrastination Scale, and Sleep Inventory were completed online by 399 university students (89% females) between the ages of 19 and 27 (M = 21.7, SD = 1.83). Future time perspective predicted lower general procrastination, which in turn was associated with lower bedtime procrastination, and consequently higher sleep sufficiency and lower daytime fatigue. Past negative time perspective predicted higher general procrastination, which in turn was associated with higher bedtime procrastination and consequently lower sleep sufficiency and higher daytime fatigue. These findings suggest that time perspective, general procrastination and bedtime procrastination may play an important role in predicting sleep sufficiency and daytime fatigue.
充足且高质量的睡眠对于身体健康、有效运转和幸福安康至关重要，然而近期趋势显示睡眠剥夺现象日益增多，尤其是在青少年和年轻人当中。一般拖延和就寝拖延（即在没有外部压力的情况下延迟上床睡觉的倾向）可能会导致睡眠剥夺和疲劳。本研究调查了时间观念的个体差异如何与两种不同的睡眠结果——睡眠充足和日间疲劳相关。对于这些关系，还考察了通过一般拖延进而通过就寝拖延的中间路径可能发挥的作用。399名年龄在19至27岁之间（平均年龄M = 21.7，标准差SD = 1.83）的大学生（89%为女性）在线完成了津巴多时间观念量表、非理性拖延量表、就寝拖延量表和睡眠量表。未来时间观念预示着较低的一般拖延，而一般拖延又与较低的就寝拖延相关，进而与较高的睡眠充足率和较低的日间疲劳相关。过去消极时间观念预示着较高的一般拖延，而一般拖延又与较高的就寝拖延相关，进而与较低的睡眠充足率和较高的日间疲劳相关。这些发现表明，时间观念、一般拖延和就寝拖延可能在预测睡眠充足和日间疲劳方面发挥重要作用。
