Teens use phone app to stop anxiety and depression from coming back
NCT ID NCT07346911
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether digital exercises on a smartphone can help teens aged 16-19 avoid relapse of depression or anxiety. Participants who have recovered from a past episode will use a research app to work through thoughts and feelings while they feel well. Some will join online group sessions with a therapist; others will work alone. If successful, the app could become a free service for teens.
