title: [Postal Survey Among Women With Turkish Migration Background in Germany - Identification, Sample Revision and Response in the InEMa Study].
abstract: OBJECTIVE
  Migrants are an important target group for mailed surveys but also difficult to reach. For planning these surveys and invitational health measures, we assessed response figures for women with and without Turkish migration background.
  
  
  METHODS
  Women aged 50 years living in Westphalia-Lippe were invited to a postal survey at 2 time points about mammography screening. Turkish migrant women were identified in the contact database by a name-based algorithm. Possible differences in sample revision and response among women with and without Turkish migration background were assessed.
  
  
  RESULTS
  Women with Turkish migration background had unknown addresses significantly more often (4.6 vs. 1.7%) and responded to the questionnaires less often (first questionnaire: 14.3 vs. 35.9%; second questionnaire: 70.7 vs. 85.6%).
  
  
  CONCLUSIONS
  For postal invitation to participate in healthcare measures, or recruitment of Turkish migrants for studies, differences in current address and readiness to respond must be taken into consideration.
