Predictors of Sleep Among Spousal Care Dyads Living With Chronic Conditions

Sleep health relates closely to physical health and well-being among older adults with chronic health conditions. However, little is known about the dyadic sleep patterns of these individuals and their spousal caregivers. Secondary analyses of the 2015 National Health and Aging Trends Study and National Study of Caregiving (N= 62 care dyads, mean age 78.59 years for care recipients and 75.77 years for caregivers) were completed to examine the sleep patterns, and related factors, of spousal dyads at both the individual and dyadic levels. Sleep measures included frequency in trouble falling back asleep and insomnia symptoms. Predictors included demographics, depressive symptoms, and positive affect for dyads and contextual factors such as dementia caregiving, care burden and support, neighborhood cohesion, and relationship quality. Multilevel dyadic and actor-partner interdependence models were used to complete analyses. Though intraclass correlation was poor (dementia care dyads ICC=0.123, non-dementia care dyads ICC=0.043), persons with dementia/spousal caregiver dyads (n=102) had more similar sleep and insomnia patterns than dyads with other chronic conditions. Poor sleep among dyads was correlated with higher care burden (β = -0.31, p
