Design outcomes

Primary

Measure	Time frame
The primary outcome measure of walking behaviour was the number of daily steps objectively measured via FitBit Flex accelerometers (objective light-PA). Participants daily steps were measured for 15 days before the intervention to establish a baseline measurement, as well as for 10 weeks during the intervention period (5 weeks gamification and 5 weeks of physical nudges phase) and for an additional 4 weeks of follow-up.	—

Secondary

Measure	Time frame
At baseline, as well as at 5 weeks, 10 weeks, and 14 weeks after the start of the intervention 1. Self-report of worktime light-PA, moderate-to-vigorous PA and SB using a novel questionnaire 2. SB at work was assessed with two-item self-report measures of workplace sitting time and breaks in sitting time 3. To assess the intensity and levels of PA in various settings (i.e. at work, at home, active transport) the validated Dutch version of the SQUASH questionnaire was utilized	—
