Data analysis
Interviews and focus groups were recorded and transcribed. Transcripts and high-level summaries were sent back to participants for confirmation of accuracy and meaning intent [To aid rigour, a reflexive approach was taken throughout the analysis process to acknowledge the researcher’s professional training, clinical experience, previous research, and role in developing the RCT exercise programs. The involvement of independent interviewers and co-authors with methodological expertise added rigour, as did processes such as negative case analysis, triangulation, journaling and constant reference to raw data.
