Readiness to change and commitment as predictors of therapy compliance in adolescents with Delayed Sleep-Wake Phase Disorder.

Objectives: Recent evidence indicates that adolescents' motivation to change sleep-wake patterns is low, despite significant impact of adolescent sleep problems on many areas of daytime functioning. The aim of the present study is to evaluate components of adolescents' motivation, and subsequent changes in behaviour.

Methods: Fifty-six adolescents, aged 13-23 (M = 15.

Cognitive "insomnia" processes in delayed sleep-wake phase disorder: Do they exist and are they responsive to chronobiological treatment?

Objective: To systematically investigate whether cognitive "insomnia" processes are implicated in adolescent Delayed Sleep-Wake Phase Disorder (DSWPD) and to examine whether these processes are responsive to chronobiological treatment.

Method: Sixty-three adolescents (M = 15.8 ± 2.

Brief school-based interventions to assist adolescents' sleep-onset latency: Comparing mindfulness and constructive worry versus controls.

Difficulties falling asleep are common among adolescents, especially during times of stress. Adolescents may thus benefit from brief techniques (15 min) that decrease pre-sleep cognitive-emotional arousal and sleep-onset latency. The present study used a 3 (intervention: mindfulness bodyscan mp3, constructive worry, control) by 3 (time: baseline, week 1, week 2) mixed-model design on a school-based sample of adolescents (N = 232; M  = 15.
