We used a semi structured guide consisting of open ended questions during in-depth interviews. All interviews were audio-taped and field notes were taken afterwards from each interview for data-gathering. The appointments with the informants were arranged by the second author of this study, who worked in Van Yuzuncu Yil University, and the interviews were conducted by the first author, who worked outside the region. The authors clarified the purposes of the study and the interviews were conducted with the informants' consent for audio-taping and for the use of their words in the report. In the institutions where the authors were affiliated, interview studies are not subject to permissions from ethical committees. Thus, the authors did not apply for approval of these institutions.
