Exploring the Relationship Between Social Support and Sleep.

Background. 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. Aims. 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. Method. The data come from an internet survey of a random probability sample of adults who reside in the United States (N = 2,287). Questions were administered on received support, satisfaction with support, meaning in life, depressive symptoms, and sleep. Results. 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. Discussion and Conclusions. 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.
