Thank you for the paper reference; this particular quote helped me understand this whole reflexivity concept:
[[“as researchers, we create worlds through the questions that we ask coupled with what we and others regard as reasonable responses to our questions.We as researchers construct that which we claim to ‘find’”.]]
Perhaps they could have done more to address reflexivity; they have mentioned that the interviewers received 'specialist training' in interviewing this client group; would that have included a mention of awareness of reflexivity? But on the whole, I'm not sure reflexivity is such a bad thing, because surely that is what shapes theory; the researcher's ability to put things into a context they can put a label to, using their own 'bias', and it is up to the (qualified) reader to either accept or dispute the findings in the research.
With this research specifically, 'quality and consistency' (whatever that is supposed to mean) was checked by other individuals, so possibly involvement of other members of the team could address the reflexivity issue.
