BackgroundHumanitarian crises increase the risk of mental health problems. Somalia has been affected by conflict, insecurity, and economic turmoil for over three decades, as well as climatic shocks. However, 80–90% of Somalis who have mental health problems do not have access to good-quality, and affordable mental health care. To develop an evidence-based, effective, equitable, and humane programme for mental health, we need to have a holistic understanding of mental health problems and care in relation to people’s perceptions, experiences, and behaviour related to mental health.MethodsWe undertook a qualitative study to explore Somalis’ perceptions and experiences of mental health problems. We conducted three key informant interviews, two in-depth interviews, nine focus group discussions, 12 observations in private and public health facilities and more than 12 informal discussions. We used case vignettes translated into Somali during our discussion. We also studied three cases with experience of mental health problems to understand care-seeking behaviour and the experiences with services available.ResultsSomalia has been moving from a traditional pastoral nomadic lifestyle to a settled one. A strong informal support system exists in the community within clans or family relations. Armed conflict often among clans, natural disasters, and khat use are the three main factors affecting mental health. The prevalence of mental problems is likely greater than is evident. It is perceived that about 95% of people suffering from mental illness remain outside of appropriate care. Few people seek care for mental health problems because they are not aware of it and because it is highly stigmatized and neglected. Those who do seek care usually go to traditional healers because of culture and cost. Resources for mental health care are grossly inadequate with a limited and often poorly trained workforce. At least two levels of barrier to mental health care exist, at the individual/family level (e.g. poor awareness of mental health and stigma) and service provider level (e.g. lack of staff and limited ability to diagnose, treat, or refer persons with mental health problems and stigma). No tool or evidence-based programme is available to address these barriers.ConclusionA qualitative data-driven mental health programme that addresses all these issues is needed with more trained mental health professionals. Given the stigma about mental health problems, there is also a need for a tool to raise awareness about mental health and the importance of mental health care among both the public and health workers.
