Critique on Qualitative study

Paper details:

There is an article attached and a series of questions that need to be answered in the course of your critique of this study.
Your grade is determined by the adequacy of your responses, based on reading the article and evaluating the trustworthiness of the qualitative data, as well as on the clarity with which you write. This paper has no page limit, but I speculate that it will be 2 pages long, that is a paragraph per question.
