This study aimed to examine whether indirectly deterring elevator use through time-targeted Point-of-Decision Prompts (PODPs) efficiently increased stair usage in a university setting.
A quasi-experimental design (pre-post design) was employed over 2 weeks in September 2023. Baseline observations were conducted for 1 week prior to signage placement at two locations. The intervention in this study lasted for 1 week, immediately following baseline observations. Three hundred and thirty-one and 384 participants were observed during the baseline and intervention periods, respectively. Logistic regression analysis was used to examine the increase in the act of ascending the stairs.
Our intervention, which focused on time-related messages, effectively increased stair usage among university students (coefficient = 0.435, p-value < 0.01). Furthermore, females (coefficient = -0.820, p-value < 0.05) and individuals aged ≥ 30 years (coefficient = 1.048, p-value < 0.01) were notably more likely to be influenced by our intervention than males and individuals aged < 30 years.
Indirectly discouraging elevator use through time-targeted PODPs may amplify the effects of the previously employed time-related messages. Our findings suggested that a deterrence nudge should primarily be directed towards promoting stair usage among females or individuals aged ≥ 30 years.
本研究旨在检验通过时间导向的决策点提示（PODP）间接阻止使用电梯是否能有效地增加大学环境中的楼梯使用。
在 2023 年 9 月，采用了准实验设计（前后设计），在两个地点进行了为期两周的 signage 放置前的基线观察。本研究的干预持续了一周，紧接着基线观察之后。分别有 331 名和 384 名参与者在基线和干预期间被观察。使用逻辑回归分析来检验爬楼梯行为的增加。
我们的干预措施集中在与时间相关的信息上，有效地增加了大学生的楼梯使用（系数=0.435，p 值<0.01）。此外，女性（系数=-0.820，p 值<0.05）和年龄≥30 岁的个体（系数=1.048，p 值<0.01）比男性和年龄<30 岁的个体更受我们干预措施的影响。
通过时间导向的 PODP 间接阻止使用电梯可能会放大先前使用的与时间相关的信息的效果。我们的研究结果表明，遏制措施应该主要针对促进女性或年龄≥30 岁的个体使用楼梯。
