Enhancing Survey Participation among Foreign-Born Populations

The Finnish Migrant Health and Wellbeing Study (Maamu) is the first large-scale population-based health examination survey among the foreign-born population in Finland, unique also at the European level. It provides information on wellbeing of three major foreign-born groups: Russian, Somali, and Kurdish. In data collection, extra effort was put into reaching the sampled persons (n=3,000), for example by recruiting bilingual personnel to carry out the data collection, reaching participation rates as high as 70%, 51%, and 63%, respectively. A comparison group of the general population was available from a general population survey. The main challenges in fieldwork included reaching sampled persons, supervision of the fieldwork personnel, and special linguistic or cultural needs. Our experiences show that participation rate can be improved by engaging the target groups in all stages of the survey process and using several recruitment strategies, ending up with succeeding in pointing out health inequalities in the population.
