Summary

This study tested whether internet-delivered cognitive behavior therapy (ICBT) can help teens aged 13-17 with mild to moderate depression. 219 participants were randomly assigned to guided ICBT (with therapist support), self-guided ICBT (without support), or usual care. The goal was to see if online therapy is effective and cost-effective, potentially making treatment more accessible.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
internet-delivered cognitive behavior therapy (ICBT)
What this could lead to
If effective, this could provide a scalable, accessible treatment option for teens with depression, reducing the need for in-person therapy.
What could go wrong
The trial is completed but results may show limited benefit over usual care, and self-guided ICBT may not be as effective as therapist-guided versions.
