The research method is based on a qualitative approach through semi structured interviews. The use of open ended questions in this qualitative study is due to the fact that this allows respondents to express their opinion, what they think, what they know, and what they practice without the influence of the researcher, thus not being limited to a set of alternatives. It facilitated the collection of information whenever occurred
deviant responses, or unclear, derived from the questions. Each phase of the research method and its outcomes are shown in Figure 1.
