This milestone contains the common qualitative research protocol. The protocol as presented here is developed in such a way that the research can be applied in other counties as part of the Community of Experts initiative of the REFRESH project (WP2). It describes the recruitment of the participants of the focus group discussions as well as the used materials. The procedures and materials are described in detail, to enable replication of the study and to make sure that the insights derived from future studies are comparable with the current results.
