Cultural tailoring for the promotion of Hepatitis B screening in Turkish migrants

This dissertation describes the development and evaluation of a culturally tailored internet intervention aimed at the promotion of Hepatitis B screening in Turkish migrants. By means of focus group discussion and a survey questionnaire, determinants of screening behaviour were assessed. Subsequently, an evidence-based intervention was developed following the Intervention Mapping protocol. The intervention targeted the identified determinants of screening, transferred knowledge about Hepatitis B, and provided a lab form for free screening. The effect of culturally tailoring on screening uptake was measured in an RCT design, by comparing it with the effect of general online tailoring and online generic information on Hepatitis B. Although culturally tailoring seemed to have some effect on the determinants of screening, as measured during the interventions, the effect of culturally tailoring on actual screening uptake could not be shown. The results of this study may serve as input for national policy on hepatitis B screening in migrant populations in the Netherlands.
