a second intervention phase in public settings boosts stair climbing success rate
Conducting a second intervention phase in public settings increased stair climbing in 86% of studies
The systematic review found that public-setting studies which incorporated a second intervention phase — likely reinforcing or building on an initial intervention — achieved the highest proportion of positive outcomes (86%). This suggests that sustained or sequential intervention strategies are particularly effective at encouraging stair use in public environments.
Combining motivational and directional signs in worksites or conducting a second intervention phase in public settings increased stair climbing in 83% and 86% of studies, respectively.
