Can a smartphone app beat the couch? new study tests online therapy for depression
NCT ID NCT02542891
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a blend of online and in-person therapy (called blended CBT) works as well as standard face-to-face therapy for adults with major depression. 105 participants were randomly assigned to either blended CBT or usual care. Researchers measured depression symptoms using a standard questionnaire to compare the two approaches.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- blended cognitive behavioral therapy (online and in-person sessions)
- What this could lead to
- If successful, this could show that online therapy is as effective as in-person therapy, making depression treatment more accessible.
- What could go wrong
- This is a completed trial with 105 participants, so results are limited in size and may not apply to everyone. Online therapy may not work for severe cases or those without reliable internet access.
