Booster therapy may help teens manage bipolar disorder
NCT ID NCT05627492
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether extra 'booster' sessions of a therapy called dialectical behavior therapy (DBT) can help youth aged 14 to 26 who have bipolar disorder or a family history of it. Participants have already completed one year of DBT in a previous study. The goal is to see how often people use the booster sessions and what leads them to need extra help.
