Findings of increased incidence rates of psychotic disorders in migrant and ethnic minority groups in various countries have been the object of considerable speculation and debate over the last decades. These findings have so far defied any unifying explanation, but they have led to an increasing attention to the role of social and environmental factors in the onset of psychotic disorders. This thesis builds from a meta-analytic study, which confirms that an increased risk for psychosis is found in both foreign-born migrants and second generation migrants born to one or two migrant parents. Further, the level of risk appears to vary according to ethnicity and social context. This thesis employed a mixed methods strategy to shed new light in our understanding of the relation between migration, ethnicity and psychosis. The quantitative component of this thesis consisted of an original study of the incidence of psychotic disorders in a South London catchment area using the Case Register Interactive Search system to ascertain incident cases. 558 incident cases were identified over a 2-year period, leading to an overall incidence rate of 59.7 cases per 100,000 person-years. As observed in previous study, increased risks for psychotic disorders were observed in people of Black Caribbean (IRR = 3.4) and Black African origin (IRR = 3.6), but also in the Other ethnic groups (IRR = 4.1). In depth qualitative interviews were conducted with 22 participants of African and Caribbean origin who have experienced a first episode psychosis to explore their illness perspectives in relation to their ethnic identity and social experiences. A thematic analysis of these accounts reveals that migrant and minority individuals perceive their psychotic illness as arising in a web of stressful events and adverse social and environmental circumstances, including discrimination, broken ties, adverse living conditions and perceived social exclusion. The various strands of this thesis all converge to indicate that the relation between migration, ethnicity and psychosis is a dynamic phenomenon embedded in the social experiences of minority individuals.
