NCT ID NCT05596318
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a digital sleep program (CBT-I) can prevent depression in pregnant people with insomnia. 456 participants will either use the CBT-I app or receive standard sleep hygiene education. Researchers will track who develops depression through one year after birth.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- digital cognitive behavioral therapy for insomnia (CBT-I) via the Sleepio app
- What this could lead to
- If it works, this could offer a simple, scalable way to prevent depression during and after pregnancy by treating insomnia early.
- What could go wrong
- This is a single trial with no phase designation, so results are preliminary. The intervention is digital and may not work for everyone, and participants with current major depression were excluded.
