. Getting a sufficient amount of sleep is an important component of living a healthy lifestyle. Consequently, it is important for researchers to identify the factors that influence sleep duration. The current study has a twofold objective. The first is to see if two types of social support are associated with sleep duration. The second objective is to see if meaning in life and depressive symptoms serve as indirect pathways in the relationship between social support and sleep. The data come from an internet survey of a random probability sample of adults who reside in the United States ( = 2,287). Questions were administered on received support, satisfaction with support, meaning in life, depressive symptoms, and sleep. The findings indicate that the amount of support that is received is associated with satisfaction with support, greater satisfaction with support is associated with a stronger sense of meaning in life, a stronger sense of meaning is related to fewer depressive symptoms, and fewer depressive symptoms is significantly associated with the likelihood of getting the recommended number of hours of sleep. Instead of merely showing that social support is associated with sleep, our findings take a modest step toward explaining how this relationship arises (i.e., through an increased sense of meaning in life and, in turn, reduced depressive symptoms). This theoretical specificity is helpful for devising interventions to improve sleep habits.
充足的睡眠是健康生活方式的重要组成部分。因此，研究人员识别影响睡眠时长的因素非常重要。本研究有两个目的。第一个目的是确定两种类型的社会支持是否与睡眠时长有关。第二个目的是确定生活意义和抑郁症状是否是社会支持与睡眠之间关系的间接途径。数据来自对居住在美国的成年人的随机概率样本的互联网调查（n=2287）。问卷中包括了关于获得的支持、对支持的满意度、生活意义、抑郁症状和睡眠的问题。研究结果表明，获得的支持数量与对支持的满意度有关，对支持的满意度越高，生活意义感越强，生活意义感越强，抑郁症状越少，抑郁症状越少，与获得推荐的睡眠时间的可能性呈显著正相关。我们的研究结果不仅仅表明社会支持与睡眠有关，而是朝着解释这种关系产生的方式（即通过增强生活意义感，进而减少抑郁症状）迈出了适度的一步。这种理论上的特异性有助于设计改善睡眠习惯的干预措施。
