Mental health programming is important in post-conflict settings such as South Sudan. Handicap International is currently implementing a project entitled “Touching Mind, Raising Dignity; to stop the stigma toward people with mental health problems” which aims to improve the social and community involvement of people living with mental health problems. This qualitative research study was conducted to understand local concepts linked to mental health problems and health-seeking in order to develop effective mental health interventions in the context of Juba, South Sudan. The study was conducted in four locations in Juba among community members, people with mental health problems, their caregivers and service providers. Focus group discussions & in-depth interviews were conducted with a total of 130 study participants. The interviews were conducted in English or by translating from Juba Arabic. The data was analysed using thematic analysis. Respondents used two wide categories when discussing people with mental health problems: mad (majnun) and sad and tired (mariid= sick). Substance abuse related madness and maratsarra (epilepsy) were genuine community concerns. Mild signs and symptoms were not recognized as mental health problems, the causes of mental health problems were viewed as numerous and complex, and mental health problems were believed to be common in South Sudan.
