Abstract Introduction:<\b>
Relatively little is still known about the feasibility of using consumer-level activity monitors as an intervention modality at population-level. Thus, it is important to increase our understanding of user attitudes towards activity monitoring, experiences related to activity monitors and the reliability and validity of activity data collected by these devices. Methods:<\b>
We selected four consumer-level tri-axial activity trackers with wrist-based optical heart rate sensors for this study (Fitbit®, Garmin®, Jawbone®, and Polar®). Using the HealthWise Wales cohort platform, we recruited a convenience sample of 30 men and women aged 29-59 years, who lived in Cardiff or its surrounding areas in South East Wales to participate in a focus group interview and in subsequent 7-day usability testing in free-living conditions. Cardiff University staff and students (n=60), aged 18-64 will be recruited to participate in a laboratory-based validation study consisting of repeated walking tests on a treadmill and sedentary tasks while sitting. Data collection for this study will be completed in April 2018. Results:<\b>
The results will be presented in relation to participant expressed ideas, feelings, and attitudes towards activity trackers and activity tracking; attitudes towards participating in a study using activity trackers; user-related, device-related, and technology adoption-related challenges of activity trackers; test-retest reliability over three repeated measurements (step count and heart rate); and validity of activity type and intensity against validated criterion standards, or direct observation. Conclusion:<\b>
These results will inform interventions aimed to promote physical activity at population-level. External funding details Funding: Wellcome Trust ISSF Population Pilot Award
