Then, I give the stakeholders a basic explanation of the current data limitations and propose the development of a project that would allow us to gather the unavailable data in the future. This shows them that I care about their needs and Im willing to go the extra mile to provide them with what they need.
How To Report Qualitative Research
Protocols of qualitative research can be published separately and in advance of the study results. However, the aim is not the same as in RCT protocols, i.e. to pre-define and set in stone the research questions and primary or secondary endpoints. Rather, it is a way to describe the research methods in detail, which might not be possible in the results paper given journals word limits. Qualitative research papers are usually longer than their quantitative counterparts to allow for deep understanding and so-called thick description. In the methods section, the focus is on transparency of the methods used, including why, how and by whom they were implemented in the specific study setting, so as to enable a discussion of whether and how this may have influenced data collection, analysis and interpretation. The results section usually starts with a paragraph outlining the main findings, followed by more detailed descriptions of, for example, the commonalities, discrepancies or exceptions per category . Here it is important to support main findings by relevant quotations, which may add information, context, emphasis or real-life examples . It is subject to debate in the field whether it is relevant to state the exact number or percentage of respondents supporting a certain statement .

Gestures made by respondents should be noted, as should the tone of voice and notes about when, where, and how spoken words may have been emphasized by respondents.
