Data analysis
Transcripts were processed with a thematic content analysis. We used
three types of coding in a grounded theory approach where open, axial,
and selective coding were alternated. 24 In the last
step, categories that stemmed from open and axial coding of the
interviews were held against the initial theoretical framework
(selective coding). Consensus was also reached amongst 2 researchers
(M.H., C.V.D.H.) about initially separately allotted codes.
