Previous research has established a link between sleep quality and psychological well-being in older adults. However, no research to date has investigated this relationship in the context of other factors known to influence both sleep and psychological well-being. Among a sample of 489 independently living older adults (ages 60 to 98), the current study examined the association between sleep quality and psychological well-being (positive emotions, negative emotions, depression) while controlling for individual differences in factors known to affect sleep: physical health, stress, physical activity, functional ability, and demographics. Multiple linear regression models showed that both better current sleep quality and better comparative sleep quality (from middle to older adulthood) predicted better psychological well-being. Implications include interventions to improve sleep quality in older adults.
