Thank you very much for your answer. I found the 2ed paper you mentioned as the most helpful. An interesting fragment concerns the info about researcher communication skills, which Kirk & Miller experienced in practise. Still I have got some deficiency :)
Maybe I should pose my question this way: What are the interpersonal communication skills of researcher in QLR? Or more widely: What are the components of interpersonal communication competence of researcher and what is their nature?
I am a "qualitative researcher" for several years and I give lectures of qualitative methodology but still I wonder if indeed every researcher should make QLR (leaving aside the very important question of formulated research problem). The interpersonal communication competence appears to me as a factor validating the results of QLR.
Thank you, Jmm, for your answer. The thing worth to underline, through paper you indicated, is a communication feedback. I think this is one of the most valuable factors of dialogue and mutual understanding. And, according to my question, there is no reliable results of QLR if our communication partner perceives us as (researches) a strangers.
I experieced this situation when I have been doing my PhD researches among the conffesion majnority groups of Lower Silesia (a voivodeship in Poland).
I do not know whether to choose a qualitative research approach must necessarily have to deal with the emotional and communicative features of the investigator.
Certainly must be inherent in the particular experimental project, research priorities, the disciplinary scope of reference, sample or population subject of the research itself.
At the same time, there is no doubt that for many qualitative research projects is essential to a great communication and interpersonal attitude on the part of the investigators involved.
This also related to the various types of investigative tools used, observations, interviews, research-action devices, etc.
