Mental Health and Wellbeing of Population with Migrant Background in Switzerland – a Scoping Review and Evidence Map of Quantitative Evidence

We aimed to map the evidence, based on population-based and migrant-specific datasets in Switzerland, on mental health and wellbeing of the population with migrant background. The research questions were: What is known from the existing quantitative evidence about the mental health of the population with migrant background living in Switzerland? What are the research gaps that can be addressed with existing secondary datasets in Switzerland? We used the scoping review approach to describe existing research. We searched Ovid MEDLINE and APA PsycInfo (2015 - September 2022). This resulted in a total of 1862 potentially relevant studies. In addition, we manually searched other sources, such as Google Scholar. We used a evidence map to visually summarise research characteristics and identify research gaps. In total, 46 studies were included in this review. Most studies used cross-sectional design (78.3%, n = 36) and theirs aims were descriptive (84.8%, n = 39). The studies tend to examine mental health or wellbeing of the population with migrant background in the context of social determinants (69.6%, n = 32). The most frequently studied social determinants were at the individual level (96.9%, n = 31). Out of 46 included studies, 32.6% (n = 15) included depression or anxiety, and 21.7% (n = 10) post-traumatic stress disorder and other traumas. Other outcomes were less commonly investigated. There was a lack of studies using longitudinal data investigating mental health of migrants that go beyond descriptive aims (i.e., explanatory and predictive), and have large nationally representative samples. Moreover, there is a need for research examining social determinants of mental health and wellbeing at the structural, family and community levels. We propose that existing nationally representative population-based surveys are used to a greater extent to study various aspects of migrants’ mental health and wellbeing.
