Breast cancer survivors' perspectives on a home-based physical activity intervention utilizing wearable technology

To gain breast cancer survivors' perspectives on participation in a home-based physical activity intervention and the factors that contributed to their acceptance and adherence to physical activity.

Semi-structured interviews were conducted with six women who had participated in a 12-week, home-based physical activity intervention using Polar A360® activity trackers. Additionally, 22 participants from the physical activity interventions provided scaled responses to barriers of physical activity on weeks 3, 6, 9, and 12. Interviews were transcribed verbatim. Thematic analysis was used for qualitative data.

Perceptions (n = 6) were categorized into three main themes including (i) Study Environment which consisted of three subthemes acrchversusfear of failure, power of results, and reminders of cancer and moving beyond. (ii) Influence of People encompassed two subthemes, i.e., personal relationships and self as a source of motivation; and (iii) Wearable Technology which was divided into two subthemes, i.e., objective insights into health and disconnect of person and technology. From the scaled responses, the most impactful barriers for participants within the intervention groups (n = 22) were "feeling busy," "lack of motivation," and "weather."

Wearable technology was perceived largely as a facilitator to physical activity in the current study, but technologic difficulties created a barrier to physical activity adherence. Additionally, participants' perceptions of study design elements and social support influenced their acceptance and adherence to the home-based physical activity interventions and should be considered to inform the design and implementation of future studies.
