Phase 1: collecting and checking stories | |
Step 1: transcription | Transcripts were made ad verbatim of each interview using audio recordings by the interviewer. |
Step 2: stories | The interviewer collected stories from the transcripts using a consensus-based format, containing agreements on narrative elements and lay-out (online supplemental file 3). |
Step 3: member check | Participants were asked whether they recognised their stories derived from the interview, small adjustments were made in the stories. |
Phase 2: analysing by main research group | |
Step 4: choosing relevant stories per perspective | After the stories were established, the main researchers continued further analysis. Stories were read and reread to familiarise with the data. A story was of relevance when it contained experiences of barriers and/or facilitators of sustained PA. Stories that where of relevance for the research question were independently chosen. Duplicates were included automatically in further analysis; inclusion of other stories was discussed, and consensus was found within duos. |
Step 5: themes | Themes were linked to each story; consensus on the themes and their contents was reached in duos per perspective (open coding). Related themes were grouped together into main themes (axial coding). We asked ourselves what the essence of the stories per main theme was and created a story web using Microsoft Excel. |
Step 6: comparing perspectives | Both duos presented the main themes from their own perspective. Themes, insights, similarities and differences were discussed. If applicable, themes were renamed and consensus was reached in the main themes. Thereafter, constant comparison method was carried out in which conclusions were checked by going back to the stories. Differences between the perspectives were noted. |
Phase 3: integration to framework | |
Step 7: integration COM-B model | A discussion was conducted about the meaning of the separate parts of the COM-B model, in order to ensure the researchers were on the same page about the meaning of the COM-B model. After reading and rereading the themes and underlying stories, the four main researchers arranged the themes into the framework of the COM-B model (figure 2). |
COM-B, Capability, Opportunity, Motivation and Behaviour; PA, physical activity.
