Table 2. A step-by-step outline of the data analysis process.

1	Familiarisation	Transcripts were read repeatedly and independently to gain an overall impression of the material.
2	Compilation and condensation	Each transcript was analysed separately and the most significant statements where GPs described their thoughts about and experiences with DAP were identified and condensed. Transcripts were read keeping the following questions in mind: “What does this tell me about the way the GP perceives DAP?” “What does DAP mean to the GP and what is his/her focus?” Subsequently, significant elements of the different DAP conceptions were identified.
3	Comparison, grouping and preliminary description	Similarities and differences between the significant statements were identified, compared and grouped using preliminary labels. Preliminary descriptions of how DAP was perceived were drawn up and labelled for each interview.
4	Formulation and labelling of different categories of description	The various ways of understanding among all interviews were collated and compared with one another, looking for similarities and differences. These were then labelled and described as different categories of description. Preliminary categories of description were compared through discussion between the co-analysts to determine if the descriptions captured the variations in views and experiences reported by the GPs.
5	Final categories of description and outcome space	Preliminary categories of description were presented to and discussed among all co-authors until a consensus was reached and the final categories of description were established. Finally an outcome space was created.
