Cross-cultural psychiatry (also known as Ethnopsychiatry or transcultural psychiatry or cultural psychiatry) is a branch of psychiatry concerned with the cultural context of mental disorders and the challenges of addressing ethnic diversity in psychiatric services. It emerged as a coherent field from several strands of work, including surveys of the prevalence and form of disorders in different cultures or countries; the study of migrant populations and ethnic diversity within countries; and analysis of psychiatry itself as a cultural product.
