Maintenance
The two stair posters were maintained after the end of the study. Considering the easy-deliver and low cost of the intervention, the employees in the intervention building planned two additional intervention phases to test the effect of different new posters with different messages designed by involving students’ opinions and improving the stairwell’s aesthetic by installing colourful stair stickers. Informal opinions from the HPU units from the other faculties suggested that the intervention will be implemented in their faculties.
