Aims
In low- and middle-income countries (LMIC) in general and sub-Sahara African (SSA) countries in particular, there is both a large treatment gap for mental disorders and a relative paucity of empirical evidence about how to fill this gap. This is more so for severe mental disorders, such as psychosis, which impose an additional vulnerability fo...

earli...
