Effects up to 20-Year Follow-Up of Preventive Cognitive Therapy in Adults Remitted from Recurrent Depression: The DELTA Study

Abstract

Up to 20 years, for MDD patients with more than 3 previous episodes, those who received PCT had significantly longer time to a first recurrence and lower recurrence risk and may have less recurrences and more depression-free time compared to TAU. This suggests long term protective effects of PCT up to 20-years.
