چکیده

This article examines the longitudinal relation between positive affect (PA) and sleep in 126 spousal Alzheimer's disease caregivers. Caregivers underwent 4 yearly assessments for the Positive and Negative Affect Schedule, the self-rated Pittsburgh Sleep Quality Index, and actigraphy to objectify nighttime total sleep time, wake after sleep onset, and percentage of sleep. Increased levels of PA and a greater positivity (i.e., positive-to-negative affect) ratio were significantly associated with better subjective sleep over the entire study period. Yearly increases in PA-even when controlling for negative affect (NA)-and in the positivity ratio were also associated with better subjective sleep. PA and actigraphy measures showed no significant relations. Increased PA is longitudinally associated with better sleep in dementia caregivers largely independent of NA.
