**3. Applications of qualitative research**

The elaboration of a research protocol or project requires asking whether qualitative research is relevant to the study's methods and goals. The choice to adopt a qualitative approach is generally based on at least one of the criteria presented in **Table 3**.

These seven elements represent contexts in which qualitative research is apposite. In order to demonstrate the application of these elements in fieldwork, **Table 3** presents examples of questions used by the authors in previous qualitative studies.

Qualitative research includes a range of analytical methods applicable in various contexts. Those that appear to be adopted most often include phenomenographic analysis, phenomenological analysis, grounded theory (GT), case studies [32], narrative analysis [31], content analysis [33–35], participatory action research [36–38], aboriginal research [39–41], discourse analysis [42–45], and systematic analysis [46, 47].
