While this is certainly useful information, I think the sentence/paragraph structure may be a bit too dense to allow for adequate reader concept absorption. Is there a way to break down these 3 concepts into a more reader-friendly bulleted or numbered list? For example, instead of the current format/structure, we might present these topics in the following way:
"Within this context, we need to:
(1) Assure there is a fair distribution of risks and benefits related to our research;
(2) Be conscientious in our recruitment efforts to support equitable representation; and
(3) Ensure special protections for vulnerable groups involved in research activities."
Then, perhaps we could begin a new paragraph with the sentence "As you plan your qualitative research study sampling method, make sure to consider..."
I think the above might be helpful for readers who are better able to absorb content in smaller, more visually bite-sized chunks. Anyway, just a thought!
