Round 1

Reviewer 1 Report

the theme is interesting with a linear research design. In my opinion, there would be a need for some improvements. At the end of the introduction, the research questions should be spelled out. In paragraph 2.2 procedures I would recommend adding, if available, scientific studies that used a similar analysis process, especially in the construction of the questionnaire. The other paragraphs of section 2 are clear and exhaustive. Sections 3 and 4 are also linear and legible. I would propose to move the last paragraph from line 316 to 323 in the conclusions. Furthermore, the usefulness of this type of study should be further developed in the conclusions
