The two researchers discussed the categorization until a consensus was reached.
A third researcher, also familiar with qualitative methods, then checked the consistency
of the categories and subcategories (Lincoln and Guba,1985).
His analysis was in agreement with the first one (i.e., 87% of codes) which is considered as a high percentage of inter-coder agreement (Lincoln and Guba, 1985; Patton, 2002).
A fourth researcher, external to the project, was then asked to validate the analysis (Lincoln and Guba, 1985).
