Up until this point, the two interviewers worked individually with six interviews each. To increase reliability, i.e. to test whether the coding would be replicated by an additional person trained in coding of qualitative data, a senior researcher (co-author MS) also read and coded all interviews. New themes were then generated. The next step was to find relevant and representative quotes to illustrate the results. In order to check the study for quality and content we followed the COREQ checklist.
