It is suggested that I use the intercoder verification in a research where I am the only coder, and whose objective is to verify the effect of the modification of the atmosphere of discussion on the topics discussed in a discussion group.
I believe it is useful to use test-retest to assess the reliability of my analyses (intracoder check), but I am not convinced of the relevance of using other coders to assess the codes assigned during my thematic analysis. If the objective of a research is to analyze the variations induced by the modification of a variable during almost similar discussion groups, using the same analyst, the same discussion plan and the same codebook, do you think it is necessary to check the agreement between coders?
ps.I work in a "codebook" or "template analysis" technique (as described in Braun and Clarke's (2022).
