Sleep and stress in adolescents: the roles of pre-sleep arousal and coping during school and vacation

Abstract

STUDY OBJECTIVES: This study explored the relationship between stress and actigraphy-measured and self-reported sleep in adolescents during periods of restricted (school) and unrestricted (vacation) sleep opportunities. We further examined whether (1) cognitive pre-sleep arousal (PSA) mediated the relationship between stress and sleep onset latency (SOL), and (2) coping moderated the effect of stress on PSA.
