Study summary

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.

Read the detailed description

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.

Results

Posted Jun 9, 2023
Limitations and caveats
Missing data were imputed except for 3 participants with data missing at baseline. Results should be interpreted with caution due to the pilot nature of the trial and data collection occurring partially during spring/summer 2020. Several outcomes (valued and engaged living, quality of life) were changed from secondary to other pre-specified, as these are likely not interpretable due to external factors (e.g., COVID-19 and social distancing).

Individual participant data

Plan to share: Yes — The investigators will provide access to all data, regardless of publication, collected as a part of this project. All external investigators must submit a written request identifying their research question(s) and specifying the data they would like to analyze. The request must include a data security plan and explanation of how the data will be stored and who will have access. All requests will be reviewed by the investigators in conjunction with UTMB's Institute for Translational Sciences key resources (in particular, the regulatory and ethics resources) to be sure appropriate NIH requirements are followed.
