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. The early literature was associated with colonialism and with observations by asylum psychiatrists or anthropologists who tended to assume the universal applicability of Western psychiatric diagnostic categories. A seminal paper by Arthur Kleinman in 1977 followed by a renewed dialogue between anthropology and psychiatry, is seen as having heralded a "new cross-cultural psychiatry". However, Kleinman later pointed out that culture often became incorporated in only superficial ways, and that for example 90% of DSM-IV categories are culture-bound to North America and Western Europe, and yet the "culture-bound syndrome" label is only applied to "exotic" conditions outside Euro-American society. Reflecting advances in medical anthropology, DSM-5 replaced the term "culture-bound syndrome" with a set of terms covering cultural concepts of distress: cultural syndromes (which may not be bound to a specific culture but circulate across cultures); cultural idioms of distress (local modes of expressing suffering that may not be syndromes); causal explanations (that attribute symptoms or suffering to specific causal factors rooted in local ontologies); and folk diagnostic categories (which may be part of ethnomedical systems and healing practices). Cultural psychiatry looks at whether psychiatric classifications of disorders are appropriate to different cultures or ethnic groups. It often argues that psychiatric illnesses represent social constructs as well as genuine medical conditions, and as such have social uses peculiar to the social groups in which they are created and legitimized.
