Protocol of a randomised clinical trial to integrate mental health services into primary care for postconflict populations in Northern Sri Lanka (COMGAP-S).

INTRODUCTION: Sri Lanka has a long history of armed conflict and natural disasters increasing the risk of mental health disorders in the population. Due to a lack of specialist services, there is a treatment gap between those seeking and those able to access mental health services. The aim of this research programme is to integrate mental health services into primary care to meet the needs of this postconflict population. METHODS AND ANALYSIS: This is a stepped wedge cluster design randomised clinical trial of the WHO mental health Gap Action Programme primary care mental health training intervention. We will provide a 10-day training to primary care practitioners of 23 randomly selected primary care facilities aimed at increasing their ability to identify, treat and manage common mental health disorders. Public health professionals and community representatives will receive a tailored training intervention to increase mental health awareness. Refresher courses will occur at 3 and 6 months post training. Supervision and monitoring will occur for 1 month pre and post training. Target sample sizes have been calculated separately for each group of participants and for each outcome.
