Abstract

The sleep intervention condition was associated with significantly greater improvements in global sleep quality and sleep onset latency compared to the control condition.

Improvements in subjective sleep quality were observed with a medium effect size.
Participants in the sleep intervention reported reduced sleep onset latency and daytime sleepiness.
Objective measures also indicated improvements in sleep onset latency in the sleep intervention group.
A small effect size was noted for reductions in anxiety symptoms among participants receiving the sleep intervention.

OBJECTIVE: Sleep problems are a major risk factor for the emergence of mental health problems in adolescence. The aim of this study was to investigate the post intervention effects of a cognitive-behavioral/mindfulness-based group sleep intervention on sleep and mental health among at-risk adolescents.

METHOD: A randomized controlled trial (RCT) was conducted across High schools in Melbourne, Australia. One hundred forty-four adolescents (aged 12-17 years) with high levels of anxiety and sleeping difficulties, but without past or current depressive disorder, were randomized into either a sleep improvement intervention or an active control 'study skills' intervention. Both programs consisted of 7 90-min-long group sessions delivered over 7 weeks. One hundred twenty-three participants began the interventions (female = 60%; mean age = 14.48, SD = 0.95), with 60 in the sleep condition and 63 in the control condition. All participants were required to complete a battery of mood and sleep questionnaires, 7 days of wrist actigraphy (an objective measure of sleep), and sleep diary entry at pre- and-post intervention.

RESULTS: The sleep intervention condition was associated with significantly greater improvements in subjective sleep (global sleep quality [with a medium effect size], sleep onset latency, daytime sleepiness [with small effect sizes]), objective sleep (sleep onset latency [with a medium effect size]), and anxiety (with a small effect size) compared with the control intervention condition.

CONCLUSION: The SENSE study provides evidence that a multicomponent group sleep intervention that includes cognitive-behavioral and mindfulness-based therapies can reduce sleep initiation problems and related daytime dysfunction, along with concomitant anxiety symptoms, among at-risk adolescents.
