Background/Objective:
Although sleep problems are linked to relationship difficulties, the mechanisms involved have not been empirically demonstrated. The present study considers self-control as such a mechanism.
Participants:
Data were collected from 342 predominantly white, middle-class, married adults.
Method:
Participants completed online questionnaires about sleep, marital aggression, and self-control, and a virtual voodoo doll task.
Results And Conclusions:
Sleep problems were associated with higher levels of aggression on all measures, and lower self-control mediated these associations. Associations did not depend on participant gender, presence of children in the home, income, or length of marriage.
