Migration, ethnicity and psychoses: evidence, models and future directions

Area of Science:

• Psychiatry
• Sociology
• Public Health

Background:

• Research indicates elevated rates of psychotic disorders in migrant and minority ethnic groups, particularly in Northern Europe.
• Increasing global migration and cultural diversity heighten the public health significance of these disparities.

Purpose of the Study:

• To review current evidence on variations in psychosis rates among ethnic groups.
• To explore social risk factors and theoretical models explaining these variations.
• To propose a socio-developmental model linking life-course social risks to psychosis rates.

Main Methods:

• Literature review of studies on psychosis rates in migrant and minority ethnic groups.
• Analysis of ecological and individual-level social risk factors.
• Development of a socio-developmental model.

Main Results:

• Significant variations in psychosis rates exist across different ethnic groups.
• Social risks, including threat, hostility, and violence, are implicated in explaining these disparities.
• A socio-developmental model posits cumulative exposure to social risks over the life course.

Conclusions:

• High psychosis rates in some migrant and minority ethnic groups are associated with systemic social risks.
• Addressing this public health issue requires multi-level strategies: social policy, community programs, and mental health service reform.
