This viewpoint discusses a conference paper titled: “Epidemiological research on mental morbidity in Chile”, which summarizes a handful of studies from 1950s in Chile covering conditions such as alcoholism, psychosis, epilepsy, and neurosis. These were the first psychiatric epidemiological population studies conducted in the Southern hemisphere, but they are largely unknown globally. We argue that the Chilean studies have important implications for modern psychiatric epidemiology, as well as for related fields such as global mental health and mental health services research. This piece starts by describing the general sociopolitical context and presenting the main methodological features of the studies. It focuses then on three specific implications for the field: 1) promoting decoloniality in psychiatric epidemiology; 2) ensuring methodological rigor and feasibility; and 3) informing the development of mental health policy and services.
