Selection of the sample
Characteristics of the sample
Open coding: after each interview had been transcribed, the data was read line by line to capture the substance and coded into significant statements that formed emerging concepts. Concepts with similar meanings were grouped together in tentative categories ( n = 18) using the constant comparative method. The categories were either labelled with actual words used by the participants (in vivo codes) or labelled with words from the professionals in the research group (in vitro codes).
Axial coding: Each category was further developed in terms of properties and dimensions, and relationships between categories were identified according to the constant comparative method. Four major categories were defined. These categories were given more abstract names than the codes belonging to them. The categories were saturated by assessing new interviews or by recoding previously assessed data.
Selective coding: A core category was identified that was central in the data and that all other categories could be related to and integrated with. This led to the description of a psychosocial process symbolised with a figure.
