Factors Influencing the Decision of Individuals with Breast Cancer to Join an Exercise Oncology Trial.

Exercise has been found to have numerous benefits for individuals with cancer undergoing treatment. The primary objective of this study was to explore factors that influence the decision to join an exercise trial for individuals with a current diagnosis of breast cancer. A theory-informed survey was administered exploring factors (i.e., attitudes, subjective norms, perceived behavioral control) that influenced participants' decision to join the "NEXT-BRCA" exercise trial. Eligible participants included self-reported females over 18 years, diagnosed with stage 1-3 breast cancer undergoing treatment and cleared for exercise by their oncologist. Survey questions were analyzed using descriptive statistics and exploratory analysis was performed to determine if associations existed between personal characteristics (age, physical activity level, co-morbid conditions) and cancer characteristics (treatment received). Seventy-four participants completed the survey. Most participants (85% of respondents) were interested in increasing their level of physical activity. The most common attitudes contributing to participant's decision to participate in the trial included feelings that exercise was beneficial for improving physical (91%) and mental health (89%). Advice from the treating oncologist was ranked as the most important factor influencing their decision to join the trial (73%). Respondents hoped to gain exercise knowledge through educational materials (72%) and a structured exercise program (70%). Findings explore why individuals with breast cancer participate in exercise trials during treatment. This knowledge will enhance recruitment of future studies using similar interventions and assist clinicians to maximize education regarding exercise and access to exercise programs for individuals with breast cancer in the future.
