2.10 QUALITATIVE DATA COLLECTION AND SAMPLE SIZE During the 6 month follow-up interview, patients are asked open-ended questions about what they liked most about the self-care program and what could be improved. A sample of 40 patients' audio-recorded interviews will be selected to be transcribed and analyzed to help explain how process factors may have impacted the effectiveness of the intervention and will also help to guide future research and practice by informing the development of a framework for outlining processes that support positive self- care experiences. Using the principle of segmentation, two groups will comprise patients who were satisfied with the intervention (one group for each type of intervention) and two groups will comprise patients who were not satisfied with the intervention (one group for each intervention type).
