Relapse/Recurrence Prevention in Major Depressive Disorder: 26-Month Follow-Up of Mindfulness-Based Cognitive Therapy Versus an Active Control.

Relapse/Recurrence Prevention in Major Depressive Disorder: 26-Month Follow-Up of Mindfulness-Based Cognitive Therapy Versus an Active Control. Behav Ther. 2018 Sep;49(5):836-849 Authors: Shallcross AJ, Willroth EC, Fisher A, Dimidjian S, Gross JJ, Visvanathan PD, Mauss IB Abstract We conducted a 26-month follow-up of a previously reported 12-month study that compared mindfulness-based cognitive therapy (MBCT) to a rigorous active control condition (ACC) for depressive relapse/recurrence prevention and improvements in depressive symptoms and life satisfaction. Participants in remission from major depression were randomized to an 8-week MBCT group (n = 46) or the ACC (n = 46). Outcomes were assessed at baseline; postintervention; and 6, 12, and 26 months. Intention-to-treat analyses indicated no differences between groups for any outcome over the 26-month follow-up. Time to relapse results (MBCT vs. ACC) indicated a hazard ratio = .82, 95% CI [.34, 1.99]. Relapse rates were 47.8% for MBCT and 50.0% for ACC. Piecewise analyses indicated that steeper declines in depressive symptoms in the MBCT vs. the ACC group from postintervention to 12 months were not maintained after 12 months. Both groups experienced a marginally significant rebound of depressive symptoms after 12 months but were still improved at 26 months compared to baseline (b = -4.12, p <= .008). Results for life satisfaction were similar. In sum, over a 26-month follow-up,...
