This study aims to compare after 6 months and 12 months, the effectiveness of a specialist model of mental health care and an enhanced usual care (task-sharing) framework, in terms of reducing mental health symptoms, reducing disability, and improving quality of life, as well as the health services costs (and potentially societal costs) associated with these outcomes in 400 patients. This study receives ground-level support from the Centre for Public Mental Health, Universitas Gadjah Mada, which manages the specialist primary mental health framework in Yogyakarta province, regional and national-level support from the Ministry of Health of Indonesia, and will be hopefully funded by the LPDP, Ministry of Finance of Indonesia.
