NCT ID NCT03175068
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether brain activity patterns can predict how well people with major depression or social anxiety respond to cognitive behavioral therapy (CBT). Over 200 participants were randomly assigned to 12 weeks of CBT or supportive therapy. Researchers measured brain activity during emotion regulation tasks before and after treatment. The goal was to understand how CBT works in the brain and for whom it is most effective.
