Abstract

During the COVID-19 pandemic, a Canadian recreation centre launched a community-based intervention to increase physical activity (PA) and reduce sedentary behaviour (SB). The Vivo Play Scientist (VPS) program provided a free wearable device (Garmin Vivofit4) that synchronized with a customized eHealth dashboard. Aim: The study investigated the feasibility and effectiveness of the VPS program through the participants’ use and experiences of the device and dashboard using the Technology Acceptance Model (TAM). Method: We employed a concurrent mixed-methods approach of online surveys and semi-structured telephone interviews and estimated the device and dashboard’s perceived usefulness and ease of use with TAM. Results: Of the 318 participants (mean age 39.8) 87 enrolled and completed the survey at baseline-T0, 4 wks-T1, and 8 wks-T2. Maximal-variation sampling was used to select 23 participants (78%, F) for interviews. We compared frequency of use, perceived usefulness and ease of use of the device and dashboard across all surveys using non-parametric statistical tests. A thematic analysis was used to analyze data. Participants had some experience using a wearable device (46%) or eHealth application (49%). A high use (≥4 d/wk.) of Vivofit4 at T1 (93%) and T2 (87%) occurred, but dashboard use was less frequent (≥1 d/wk. T1 54.0% and T2 47.1%). Average levels of perceived usefulness and ease of use for the Vivofit4 and dashboard remained constant from T1 to T2. Average daily PA scores decreased from T1 to T2 (4.9 to 4.5; p = 0.017). Conclusion: Participants were guarded about the value of the dashboard use and reported several challenges associated with the VPS program, but the free device and dashboard did provide PA support during the pandemic.
