Low language proficiency (LP) in migrants is linked to higher rates and severity of mental health disorders. Improving LP may positively impact migrant mental well-being.
Area of Science:
- Psychiatry
- Migration Studies
- Public Health
Background:
- Migrants often face unique mental health challenges.
- The role of language proficiency (LP) in migrant mental health is not fully understood.
Purpose of the Study:
- To evaluate the association between language proficiency and the prevalence/severity of mental disorders in migrants.
- To explore how sociodemographic and migration factors influence this association.
Main Methods:
- Systematic review of studies from MEDLINE, PsycArticles, EMBASE, and PsycInfo databases (searched April 2020).
- Inclusion of original studies reporting psychiatric symptoms/disorders in migrants and considering linguistic factors.
- Analysis of 41 selected studies from an initial 1,944 citations.
Main Results:
- A significant negative association between low language proficiency and mental disorder prevalence/severity was reported in 35 of 41 studies.
- Inadequate LP was linked to psychotic, mood, anxiety, and post-traumatic stress disorders.
- Longitudinal studies indicated that improved LP over time positively affected mental disorder prevalence or symptom severity.
Conclusions:
- Inadequate language proficiency is consistently associated with increased mental health issues in migrant populations.
- Improving migrants' language proficiency upon arrival may be a beneficial public health intervention.
- Further prospective research is recommended to solidify these findings.
