Objective:
This study assessed the effect of a default nudge to reduce sedentary behaviour at work over time.
Design And Main Outcome Measures:
A field study was conducted at a governmental organisation. In the present study, the default setting of sit-stand desks (SSDs) was changed from sitting to standing height during a two-week intervention. Stand-up working rates were calculated based on observations that were done prior to, during, two weeks after and two months after the intervention. Additionally, a pre-measure survey (n = 606) and post-measure survey (n = 354) were completed. Intention and social norms concerning stand-up working were compared for the 183 employees who completed both pre- and post-assessments (45.4% female, Mage = 44.21).
Results:
Stand-up working rates raised from 1.82% in the baseline to 13.13% during the intervention. After the nudge was removed the percentage was 10.01% after two weeks and 7.78% after two months. A multilevel analysis indicated a significant increase in both intention and social norms after the nudge intervention.
Conclusions:
This study shows that a default nudge can increase stand-up working rates in offices with SSDs at least until two months after the nudge intervention.
