Summary

A cohort analytic study (i.e., observational study following a cohort over time to compare outcomes between those exposed and unexposed to an intervention) was conducted over a 17-week period (March 7, 2022 to June 30, 2022). The study consisted of a five-week baseline period (March 7, 2022 to April 10, 2022). During the baseline, Telus Wellbeing users earned FI for meeting personalized but static daily step goals. A 12-week intervention period followed (April 11, 2022 to June 30, 2022). During the intervention period, users were randomized by a senior Telus Wellbeing software engineer into either control (i.e., continuing with their personalized static goal) or intervention groups (i.e., testing the new ML-driven 'Smart Mode' feature offering personalized and adaptive daily step goals) using a random number generator in Python (version 3.9; i.e., non-pi package random binomial). The randomization ratio was about 1:2 in favour of the intervention group. Both groups were informed they would be testing a new 'Smart Mode' feature at intervention onset, however, only those allocated to the intervention group received ML-driven goals. Notably, the study sample consisted of more highly engaged users (e.g., registered on the app at least five weeks prior to the intervention, took initiative to synchronize their activity trackers with the app). The Strengthening the reporting of observational studies in epidemiology (STROBE) statement flow chart and checklist for cohort studies is provided.
