Through the consent form, participants were introduced to the researchers, explained the background, purpose and procedure for conducting the study. The respondents were informed about their rights. Voluntary participation was ensured, and participants had the autonomy to refuse questions or leave the interview at any point. They had the right to ask questions at any point before, during or after the interview. All interviews were conducted by trained personnel and in conditions of privacy. Confidentiality was maintained by using auto-generated participant codes instead of names.
