Primary-Care Based Mindfulness Intervention

There is significant public health burden of chronic trauma exposure in low income, predominantly ethnic minority, urban communities, which is reflected in the extraordinarily high levels of trauma-related psychiatric disorders, particularly PTSD and MDD. Despite this, limited access to behavioral health treatment and significant barriers to treatment engagement and success remain and integrating mind-body approaches in medical settings could be a critical next step in treating chronically traumatized individuals in these urban settings. This study will utilize a randomized controlled trial design along with a multi-method assessment approach to ascertain the feasibility, acceptability, and preliminary mechanisms of action and outcomes of mindfulness-based cognitive therapy versus wait-list control in 80 African Americans with chronic trauma exposure and comorbid PTSD and MDD symptoms. Participants will be randomized to an 8-session (90 minutes each) group intervention or wait-list control. The researchers will examine the retention and follow-up rates, participants' report of acceptability and interest in the intervention, and examine barriers to treatment engagement through self-report measures and exit interviews. This study will also investigate preliminary mechanisms of action and outcomes of the mindfulness intervention in targeting emotion regulation and autonomic processes by measuring self-report of emotion dysregulation using the Difficulties in Emotion Regulation Scale and autonomic arousal to trauma cues using eSense technology to assess skin conductance during administration of Standardized Trauma Interview. Latent growth modeling will assess relative changes in emotion dysregulation and autonomic function over time through intervention and 1 month follow-up.
