Overview

Randomised controlled trial shows app-based cognitive behavioural therapy reduces insomnia severity in adults, suggesting a viable intervention for sleep issues.

Key Points

  • The intervention led to a significant improvement in sleep hygiene measures, with users achieving a reduction of 3.5 points on the Sleep Hygiene Index.
  • Post-intervention, 48% of the intervention group reached remission compared to 18% of the control group, showing the effectiveness of the app.
  • Participants reported better sleep latency and efficiency, alongside reduced nocturnal awakenings after engaging with the 7-week course.
  • The findings indicate that various sleep hygiene behaviors can be significantly modified, suggesting potential long-term benefits for users.
