ZusammenfassungResponse rates for health surveys have been dropping during the past few decades. Among persons with migration background, response rates are even lower than in the original population. In order to counter this, the German National Cohort (NAKO) used several recruitment strategies to maximize participation, reduce non-response bias, and to produce locally representative samples from the general population in the study regions. For a random sample of Berliners of Turkish descent, home visits were conducted instead of the usual third reminder letter, as a means to increase participation and minimize non-response bias. We compare how this strategy performed among persons with a Turkish migration background, and investigate if this strategy is to be recommended.
