1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundAmong adolescents, internalizing disorders are a leading cause of the global burden of disability and death due to suicide. There is a critical need to prevent first-lifetime onsets of internalizing disorders, particularly among high-risk adolescents. Insomnia and poor sleep have been robustly linked to internalizing disorders in adolescents. The present trial will examine if brief, web-based Cognitive Behavioral Therapy for Insomnia (CBT-I) reduces insomnia symptoms, improves sleep quality, and improves subthreshold internalizing symptoms in never-clinically depressed or anxious adolescents with sleep problems (insomnia severity scores indicating subthreshold insomnia or higher) who are at risk for internalizing disorders due to a parental history of these disorders.

methodsThis trial uses a two-arm, single-blinded, parallel group randomized controlled design (N = 50). Participants in the treatment group will complete a web-based CBT-I intervention (return2sleep) that is comprised of 7 sessions (six adolescent sessions and one parent session). Participants in the control group will receive a psychoeducational pamphlet and be encouraged to continue treatment (if any) as usual. Insomnia severity, sleep quality, and depressive and anxiety symptoms will be assessed at three time points (baseline, immediately post-treatment, and three months post-treatment). Additionally, clinically significant internalizing disorders in adolescents will be assessed using diagnostic interviews. DISCUSSION: Web-based CBT-I is a non-invasive, economical, and easily administered intervention targeting sleep which is a potentially modifiable risk factor for the onset of depression and anxiety. Results from this trial will inform larger-scale effectiveness trials to examine whether, via interventions to improve sleep, it is possible to prevent currently healthy, but high-risk, adolescents with sleep problems from developing internalizing disorders for the first time in their lives, thereby preventing a lifelong cascade of adverse psychosocial outcomes.
