Bedtime and the Budget: Longitudinal, Actor–Partner Connections between Sleep Quality and Financial Management Behaviors in Newlywed Couples

Research from the American Psychological Association suggests that approximately 67% of U.S. adults are getting more or less sleep than desired, and over 80% of U.S. adults ages 18–43 are stressed about finances. Cross-sectional evidence suggests that there may be a connection between the two. That is, some cross-sectional research suggests a contemporaneous association between sleep quality and finances. Using two waves of newlywed dyadic data (N = 1497 couples), we estimated a longitudinal structural equation model to test actor–partner associations between husbands’ and wives’ sleep quality and financial management behaviors. In these associations, we examined husbands’ and wives’ marital satisfaction as potential mediating variables. We found that both husbands’ and wives’ sleep quality longitudinally predicted their own and their partner’s financial management behaviors. Additionally, husbands’ and wives’ sleep quality—through wives’ marital satisfaction—indirectly and longitudinally predicted wives’ financial management behaviors. As financial practitioners encourage newlywed couples to consistently experience quality sleep, their financial management behaviors may benefit. We suggest that for newlywed couples, both partners’ bedtime may be longitudinally connected to both partners’ management of their budget.
