Daytime Affect and Parent-Child Interactions as Predictors of Sleep Quality in Healthy and Depressed Adolescents

Adolescence is often characterized by an increase in negative affect and depressive symptoms. Sleep problems are common in depressed adolescents. Previous research indicates that sleep and mood are bidirectionally associated. However, the predictive relationship between daily mood and sleep in the next night remains less clear. The current study aimed to compare subjective sleep quality between healthy and depressed adolescents. Secondly, this study aimed to examine whether the daily mood of the adolescents and parents, as well as parent-child interactions, predict sleep quality. A 14-day longitudinal observational study using ecological momentary assessment (EMA) was conducted in a sample of depressed (n = 80) and healthy adolescents (n = 35), aged between 11 and 17 years (M = 15.79, SD = 1.46), and their parents (n = 216). 65.6% of the participants were female and 34,4% were male. Participants completed four daily assessments on their mobile phones.

Participants completed four daily assessments on their mobile phones. The results indicate that adolescents with depression suffer from poorer sleep quality than healthy adolescents (MD = 1.60 (95% CI, 1.39 to 1.82), t(366.88) = 14.48, p < 0.001). Daily positive affect of the adolescent (b = 0.16, t(773.05) = 3.21, p < 0.001) and daily positive affect of the parents (b = 0.18, t(605.26) = 2.57, p = 0.01) were associated with better sleep quality of the adolescents. The effect of adolescent positive affect disappeared when controlling for other variables. Increasing positive affect during the day might consequently improve sleep quality. Interventions should consider the role of the family environment in adolescent sleep.Show less
