Background: Post-traumatic stress disorder (PTSD) is a common mental health disorder after natural disasters. Without treatment survivors of earthquake would continue suffering from PTSD for many years. There are not many short-term trauma-focused psychosocial therapies that have been examined after natural disasters in developing countries. This study investigates the effectiveness of a 4-session revised narrative exposure therapy (NET-R), and 2-session group-based control-focused behavioural treatment (CFBT-R) delivered by non-specialists with minimum supervision.~Methods/Design: Participants would be identified and recruited through a door-to-door survey of families severely affected by the 2015 earthquake in Bhaktpur municipality of Nepal. PTSD Checklist for DSM-5 (PCL-5) will be used to screen all adult survivors (aged 18 and above) for the possible presence of PTSD, and the CAPS-5 interview will be used for the diagnosis of current PTSD. Investigators aim to include 240 consenting participants in a single blind randomised controlled clinical trial. All participants will be randomly allocated to one of three treatment conditions (N = 80 each): 4-session revised narrative exposure therapy (NET-R), 2-session group-based control-focused behavioural treatment (CFBT-R) involving instructions to conduct self-exposure, or a 3-month waiting list. In both NET-R and CFBT-R interventions, treatment sessions will last 90 minutes; NET-R will be delivered within a week while CFBT-R will be done over 2 weeks. All participants will be subjected to blind assessments for PTSD symptom severity with CAPS-5 and Fear and Avoidance questionnaire at pre-treatment (T0) and 3-month post-treatment (T1).~Discussion: The results from the post-treatment measurement would provide strong empirical reference of the safety and effectiveness of trauma-focused short-term therapies (NET-R and CFBT-R) for mass trauma survivors in developing countries like Nepal. It may also provide information on who may benefit most from which type of intervention.
The purpose of this study is to determine whether two types of short-term trauma-focused therapies (individual Narrative Exposure Therapy and group-based Control-Focused Behavioural Treatment) are effective in the treatment of chronic PTSD in earthquake survivors of Nepal.
