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.

Physical activity is associated with clinically important differences in health-related quality of life among rural and small-town breast cancer survivors.

PURPOSE: The primary purpose of this study was to examine differences in health-related quality of life and fatigue between rural and small-town (RST) breast cancer survivors meeting and not meeting public health physical activity (PA) recommendations. METHODS: Using a retrospective survey design, RST breast cancer survivors (N = 524) residing in Southern Alberta, Canada completed a mailed questionnaire assessing self-reported prediagnosis, on treatment, and current PA behavior, and current health-related quality of life and fatigue. RESULTS: Analyses indicated 44.1%, 13.7%, and 34.7% of RST breast cancer survivors met public health PA recommendations during prediagnosis, on treatment, and post-treatment (i.e., current) time periods, respectively. Multivariate analyses of variance suggested indicated survivors currently meeting PA recommendations reported clinically advantageous differences in health-related quality of life and fatigue symptoms than survivors not currently meeting PA recommendations. Repeated measures analyses also indicated significant differences in PA behavior across the three cancer-related time periods (all p < 0.01). CONCLUSIONS: The results of this study provide evidence that RST breast cancer survivors have similar PA behavior estimates across the cancer trajectory to urban survivors. Being physically active was associated with clinically important advantages with respect to health-related quality of life and fatigue. Strategies designed to facilitate PA behavior in the RST breast cancer survivor population are warranted.

Predictors of physical activity among rural and small town breast cancer survivors: an application of the theory of planned behaviour.

The primary objective of this study was to investigate the utility of the two-component theory of planned behaviour (TPB) in understanding physical activity intentions and behaviour in rural and small town breast cancer survivors. The secondary objective was to elicit the most common behavioural, normative and control beliefs of rural and small town survivors regarding physical activity. Using a cross-sectional survey design, 524 rural and small town breast cancer survivors completed a mailed survey that assessed physical activity and TPB variables. Physical activity intention explained 12% of the variance in physical activity behaviour (p < 0.01) while the TPB constructs together explained 43% of the variance in physical activity intention (p < 0.01). Unique behavioural, normative and control beliefs were elicited from the sample. The two-component TPB framework appears to be a suitable model to initiate an understanding of physical activity determinants among rural and small town breast cancer survivors. These data can be used in the development and establishment of physical activity behaviour interventions and health promotion materials designed to facilitate physical activity behaviour among rural and small town breast cancer survivors.
