Study Overview
Brief Summary
Mixed methods (qualitative and quantitative) cluster randomized pilot feasibility trial (n=40) to refine the the Brief Relaxation, Education and Trauma Healing (BREATHE) Ethiopia intervention and explore effectiveness and implementation. Fifty patients will be enrolled across the pre-pilot and the pilot to account for potential treatment dropout. Eight health care centers will be randomized to Treatment or Waitlist conditions.
- Primary outcomes: Change in hypothesized treatment mechanisms: (1) increased knowledge about PTSD; reductions in (2) PTSD-related stigma; (3) trauma-related cognitions; and (4) self-reported arousal; (5) increased use of stress management strategies; and (6) reductions in physiological arousal as measured by increased heart rate variability.
- Secondary outcomes: Change in symptoms and functional impairment. Reductions in (1) PTSD (2) depression and anxiety symptoms, and (3) functional impairment.
- Process evaluation: Mixed methods multi-stakeholder process evaluation of the implementation of the intervention as measured by the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance). We will collect qualitative data on Adoption and Implementation (e.g. facilitators and barriers to intervention delivery) and quantitative assessment of patient and provider participation and retention (Reach), satisfaction (Adoption) and fidelity (Implementation).

Arms & Interventions
BREATHE Intervention
Five session program, with additional sessions provided based on the individual's learning style and needs. Sessions are designed to be 20 to 30 minutes long, to accommodate the needs of the primary health care centers. Sessions will ideally be conducted once per week, but may be conducted as infrequently as once per month.
Intervention: BREATHE Intervention (Behavioral)
Waitlist Treatment as Usual
Typical primary care treatment which will include medication management and follow-up at the health facilities, at at least the same frequency as treatment arm. At the End of the trial participants will be able to receive the BREATHE Ethiopia PTSD treatment
Intervention: Waitlist Treatment as Usual (Behavioral)
Outcomes
Primary Outcomes
Change in Stress management strategy use
Time Frame: Day 0 baseline, 3 months
Changes in use of the breathing retraining techniques as measured by self- and caregiver-reports during in-session homework review.
Change in PTSD Related Stigma
Time Frame: Day 0 baseline, 3 months
Changes in levels of PTSD Related Stigma measured by The Internalized Stigma of Mental Illness Scale (1 minimal stigma to 4 severe internalized stigma).
Change in Trauma-related cognitions
Time Frame: Day 0 baseline, 3 months
Changes in levels of trauma-related cognitions assessed by the Post-Traumatic Cognitions Inventory (36-252 higher scores indicating higher incidence of negative trauma related cognitions).
Change in Self-reported arousal
Time Frame: Day 0 baseline, 3 months
Changes in self-reported arousal levels measured with Self-Assessment Manikin (Self-Assessment Manikin measures arousal using 3 subscales: Valence, 1 unpleasant to 5 pleasant; Arousal rating, 1 calm to 5 excited; and Dominance, 1 independent to 5 dependent).
Change in Physiological arousal
Time Frame: Day 0 baseline, 3 months
Changes in physiological arousal levels measured by heart rate variability (HRV).
Change in PTSD Knowledge
Time Frame: Day 0 baseline, 3 months
Changes in levels of PTSD Knowledge measured by the PTSD Knowledge Test (0-14, higher scores indicating more PTSD knowledge).
Secondary Outcomes
- Change in PTSD Symptoms(Day 0 baseline, 3 months)
- Change in Depression Symptoms(Day 0 baseline, 3 months)
- Change in Anxiety Symptoms(Day 0 baseline, 3 months)
- Change in Functional impairment(Day 0 baseline, 3 months)
