The Effectivness of Combined of Brief Behavioral Activation Therapy and Mindfulness-based Cognitive Therapy in Patients with Major Depressive Disorder

Major depressive disorder (MDD) is currently ranked the third leading cause of disability in the world. The aim of the present study was to examine the effectivness of combined of brief behavioral activation therapy (BATD) and mindfulness-based cognitive therapy (MBCT) in patients with major depressive disorder. This research was administrated in a single subject design framework. Four patients (1 male، 3 female، ages 26-38) with MDD participated in the study. The participants were randomly assigned to four treatments (MBCT، BATD and Combined of BATD and MBCT to reverse sequence). To collect data Beck Depression Inventory (BDI-II) and the Ruminative Responses Subscale (RRS) were administered during pretreatment، during treatment at Sessions 2، 4 and 6، Session 8، and at 1-month follow-up. The visual inspection of charts and size effects indicated significant decrease in depression symptoms and rumination of participants. These preliminary findings provided support for the role of Combined of BATD and MBCT in reducing depression symptoms and rumination in Patients with MDD.
