Abstract
Purpose
This study examined whether increasing sleep duration was associated with changes in daily affect, specifically, increases in positive affect (PA) and decreases in negative affect (NA), among short-sleeping adolescents.
Methods
Healthy, short-sleeping adolescents (reporting <8 h sleep on school nights based on parent and adolescent screening questionnaires, n = 41, 14-17 years) participated in 1 week of baseline monitoring, then were randomized to either sleep extension (EXT; +90 min in bed; n = 21) or habitual sleep (HAB; n = 20) for 2 weeks. Both conditions established fixed bedtime and rise-time to reduce sleep variability. Sleep duration was assessed via wrist actigraphy. Participants completed the 22-item Profile of Mood States twice daily: soon after waking and at bedtime during the 3-week protocol.
