Abstract
AbstractBackgroundMajor Depressive Disorder (MDD) is highly prevalent and was associated with greater morbidity, mortality (including suicide), and healthcare costs. By 2030, MDD will become the leading cause of disability in high-income countries. Notably, among patients with a previous experience of a major depressive episode, it was indeed estimated that up to 85 % of those patients will suffer from relapse. Two main factors were associated with a significantly higher risk of relapse: poor medication adherence and low self-efficacy in disease management. Interestingly, these issues could become the targets of psychoeducational programs for chronic diseases. Indded psychoeducational program for depression are recommended in international guidelines, but have not yet been proposed in France.Methods/DesignWe propose to evaluate the first French psychoeducational program for depression “ENVIE” in a multicenter randomized controlled trial. The group intervention will include 9 weekly sessions. Its aim is to educate patients on the latest knowledge on depression and effective treatments through didactic and interactive sessions. Patients will experiment the latest innovating psychological skills (from acceptance and commitment therapy) to cope with depressive symptoms and maintain motivation in behavioral activation. In total, 332 unipolar non-chronic (<2 years) outpatients with moderate to severe depression, without psychotic features, will be randomly allocated to the add-on ENVIE program (N = 166) or to a waiting list (N = 166). The follow-up will last 15 months and include 5 assessment visits.The primary endpoint will be the remission rate of the index episode at 15 months post-inclusion, defined by a Montgomery and Asberg Depression Rating Scale (MADRS) score ≤ 12 over an 8-week period, and without relapse during follow-up. We will also assess the response rate and relapse at 15 months post-inclusion, hospitalization rate and adherence to treatment during the follow-up period, quality of life and global functioning upon inclusion and at 9 and 15 months post inclusion.DiscussionIf the proposed trial shows the effectiveness of the intervention, but also an increased remission rate in depressed outpatients at 15-months post-inclusion, in addition to improved treatment adherence in patients, it will further promotes arguments in favor of a wide dissemination of psychoeducational programs for depression.Trial registrationThis trial is registered under number 2015-A00249-40 (PURE clinical trial: NCT02501226) (June 30th, 2015).
