OBJECTIVES: This study investigated the concurrent and longitudinal dyadic associations of loneliness with sleep duration and quality between wives and husbands among retired couples over 10 years. METHOD: ) for both husbands and wives. Actor-Partner Interdependence Models were conducted to explore the dyadic associations of loneliness with sleep duration and quality between wives and husbands. Mediation analyses were performed to examine the potential mechanisms underlying the association. RESULTS: At the individual level, higher loneliness predicted shorter sleep duration and poorer sleep quality concurrently and longitudinally. At the partnership level, higher wives' loneliness significantly predicted worse sleep quality of their husbands in the long run, through increasing husbands' loneliness and decreasing sleep quality of their own over time. CONCLUSION: The results indicate that the dyadic relationship of sleep and loneliness between husbands and wives among older couples warrants attention. Couple-based intervention would be desirable to promote sleep health among older adults.
