A qualitative study examining newly diagnosed breast cancer patients' experiences of participating in the Alberta Moving Beyond Breast Cancer (AMBER) prospective cohort study.

Background: Decisions to participate in cancer trials are associated with uncertainty, distress, wanting to help find a cure, the hope for benefit, and altruism. There is a gap in the literature regarding research examining participation in prospective cohort studies. The aim of this study was to examine the experiences of newly diagnosed women with breast cancer participating in the AMBER Study to identify potential strategies to support patients' recruitment, retention, and motivation.

Methods: Newly diagnosed breast cancer patients were recruited from the Alberta Moving Beyond Breast Cancer (AMBER) cohort study. Data were collected using semi-structured conversational interviews with 21 participants from February to May 2020. Transcripts were imported into NVivo software for management, organization, and coding. Inductive content analysis was undertaken.

Results: Five main concepts associated with recruitment, retention, and motivation to participate were identified. These main concepts included: (1) personal interest in exercise and nutrition; (2) investment in individual results; (3) personal and professional interest in research; (4) burden of assessments; (5) importance of research staff.

Conclusions: Breast cancer survivors participating in this prospective cohort study had numerous reasons for participating and these reasons could be considered in future studies to enhance participant recruitment and retention. Improving recruitment and retention in prospective cancer cohort studies could result in more valid and generalizable study findings that could improve the care of cancer survivors.
