Trajectories of insomnia symptoms and insufficient sleep duration in early adolescents: associations with school stress.

Study Objectives: We examined how adolescents' sleep patterns (i.e. insomnia symptoms and sleep duration) change from early- to mid-adolescence and whether adolescents follow different trajectories.

Technology use as a sleep-onset aid: are adolescents using apps to distract themselves from negative thoughts?

Study Objectives: The aim of this study was to; (1) explore whether adolescents use technology as distraction from negative thoughts before sleep, (2) assess whether adolescents who perceive having a sleep problem use technology as distraction more compared to adolescents without sleep complaints, and (3) collect qualitative information about which devices and apps adolescents use as a distraction.

Methods: This study used a mixed-methods cross-sectional design, where 684 adolescents ( = 15.1, = 1.

Preventing sleep deficit in adolescents: Long-term effects of a quasi-experimental school-based intervention study.

Adolescents are at risk of sleep deficit, which has serious consequences for their daytime functioning. However, school-based interventions to improve sleep have shown limited success. This might be due to the content of the programmes (e.

Bidirectional associations between adolescents' sleep problems and impulsive behavior over time.

Objective/background: Adolescents who experience sleep problems are less able to resist impulses. Furthermore, youths who show more impulsive behaviors are, in turn, assumed to have more sleep problems, which sets the stage for a negative cycle over time. Empirical research has shown some evidence that sleep problems affect impulse control, but the bidirectional link has previously not been tested.
