Couples' Sleep and Psychological Distress: A Dyadic Perspective

Area of Science:

• Gerontology
• Sleep Science
• Social Psychology

Background:

• Sleep is crucial for physical and psychological well-being in aging adults.
• Existing research primarily focuses on individual sleep, neglecting its interpersonal dynamics.
• Older adults' sleep quality and its association with distress warrant further investigation at the couple level.

Purpose of the Study:

• To construct and validate dyadic sleep measures for older couples.
• To examine the predictive capacity of these dyadic sleep measures on individual sleep and psychological distress.
• To establish sleep as a dyadic interpersonal process in older adults.

Main Methods:

• Analysis of two waves (2009, 2013) of time diary data from older couples.
• Development of dyadic sleep measures: bedtime/wake-up time differences, and couple's sleeping/waking routines.
• Application of multilevel regression models controlling for covariates.

Main Results:

• Significant discordance observed in older couples' sleep habits.
• Dyadic waking patterns predicted individual sleep duration.
• Dyadic sleep patterns independently predicted psychological distress, even after accounting for individual sleep and other factors.

Conclusions:

• Sleep functions as a dyadic interpersonal process, not solely an individual one.
• Dyadic sleep measures are essential for understanding older adults' sleep and well-being.
• Future research and surveys should integrate couple-level sleep assessments.
