Common mental health problems in immigrants and refugees: general approach in primary care

Background:

Recognizing and appropriately treating mental health problems among new immigrants and refugees in primary care poses a challenge because of differences in language and culture and because of specific stressors associated with migration and resettlement. We aimed to identify risk factors and strategies in the approach to mental health assessment and to prevention and treatment of common mental health problems for immigrants in primary care.

Methods:

We searched and compiled literature on prevalence and risk factors for common mental health problems related to migration, the effect of cultural influences on health and illness, and clinical strategies to improve mental health care for immigrants and refugees. Publications were selected on the basis of relevance, use of recent data and quality in consultation with experts in immigrant and refugee mental health.

Results:

The migration trajectory can be divided into three components: premigration, migration and postmigration resettlement. Each phase is associated with specific risks and exposures. The prevalence of specific types of mental health problems is influenced by the nature of the migration experience, in terms of adversity experienced before, during and after resettlement. Specific challenges in migrant mental health include communication difficulties because of language and cultural differences; the effect of cultural shaping of symptoms and illness behaviour on diagnosis, coping and treatment; differences in family structure and process affecting adaptation, acculturation and intergenerational conflict; and aspects of acceptance by the receiving society that affect employment, social status and integration. These issues can be addressed through specific inquiry, the use of trained interpreters and culture brokers, meetings with families, and consultation with community organizations.

Interpretation:

Systematic inquiry into patients’ migration trajectory and subsequent follow-up on culturally appropriate indicators of social, vocational and family functioning over time will allow clinicians to recognize problems in adaptation and undertake mental health promotion, disease prevention or treatment interventions in a timely way.Changing patterns of migration to Canada pose new challenges to the delivery of mental health services in primary care. For the first 100 years of Canada’s existence, most immigrants came from Europe; since the 1960s, there has been a marked shift, with greater immigration from Asia, Africa, and Central and South America.¹ The mix differs across the provinces, although nearly all immigrants settle in Canada’s largest cities.² The task of preventing, recognizing and appropriately treating common mental health problems in primary care is complicated for immigrants and refugees because of differences in language, culture, patterns of seeking help and ways of coping.^3–6In consultation with experts in immigrant and refugee mental health, we reviewed the literature to determine associated risks and clinical considerations for primary care practitioners in the approach to common mental health problems among new immigrant or refugee patients.^7–10 In this paper, we review the effect of migration on mental health, use of health care and barriers to care. We outline basic clinical strategies for primary mental health care of migrants including the use of interpreters, family interaction and assessment, and working with community resources.
