Narrative Visualization for Breast Cancer Survivors' Physical Activity

This study tests the feasibility and acceptability of a physical activity intervention that combines use of a wearable activity monitor with a scrapbook. Half of the participants will receive this enhanced intervention, while the other half will receive a wearable activity monitor with a standard step log.

Women breast cancer survivors could benefit from increased physical activity but are in need of greater motivation to be active. Interventions that use wearable activity monitors and mobile apps have shown promise in the short-term, but use drops off over time. Reports have suggested that users find the step data provided to be unclear and not very personally meaningful. The ultimate purpose of this line of research is to test whether enhanced motivational feedback, using scrapbooks, can increase motivation for activity. The scrapbooks will target integrated regulation, which is a type of motivation related to personal identity and values. Participants who receive this intervention will draw their step graph, add photographs and stickers an explanations to the graph, and answer reflection questions daily. Before testing the effects of this intervention on physical activity, the investigators must first ensure that the materials and procedures are feasible and acceptable. This small pilot study will allow the research team to iteratively test scrapbook materials and improve upon them for use in future studies. The investigators will compare an intervention using the enhanced materials to an intervention using only the wearable device, app, and a standard step log without scrapbook or reflection components. In addition to the primary outcome of feasibility (use of the scrapbook), the investigators will also explore the effects of the intervention on steps, motivational and values-related outcomes, and various aspects of feasibility and acceptability.
