Predictive effects of daily sleep on social motivation and social activity.

Abstract

This study examined the predictive effect of day-to-day variations in sleep on self-reported social motivation and social activity in 126 parents of young children with sleep problems. Controlling for other sleep factors, worse subjective sleep quality predicted less morning sociability and social motivation throughout the day. Unexpectedly, longer sleep duration predicted less social activity the following day. Sleepiness at wakeup predicted morning sociability, but not social motivation or activity throughout the day. This highlights the importance of good sleep quality for motivation to socialize, but also the complexity of investigating the relationship between sleep and social measures in daily life.
