Supporting data for “Sleep Variability in Youths – From Clinical Correlates to Treatment Implications”

The present thesis aimed to enhance understanding of the clinical correlates and intervention efficacy related to intraindividual sleep variability in youths with a delayed circadian phase (eveningness preference, delayed sleep-wake phase disorder), as well as in those under clinical conditions (depressive disorders or insomnia disorder). The correlates of sleep variability were investigated in two case-control studies (Chapter 2 and 3). Chapter 4 conducted a secondary analysis of a randomized controlled trial to examine the effects of CBT-I with adjunctive BLT on reducing sleep variability in youths with insomnia and eveningness.
