We aimed to investigate the effectiveness of health belief model-based nudge messaging on engagement in stretching that was either threat-based or benefit-based.
A quasi-experimental design allocated the participants (N=69) into three groups: the threat nudge group, which received messages emphasizing perceived susceptibility and severity; the benefit nudge group, which received messages on the advantages of stretching; and the control group, which received no messages. The study was conducted in South Korea from October to November 2024. Participants' engagement in stretching was measured over a six-week period using the health application, which provided the stretching exercise sessions and tracked and recorded their duration.
The threat nudge group exhibited the largest increase in stretching behavior, significantly outperforming both the benefit nudge group and the control group. The benefit nudge group showed an improvement but it tended to be a generally smaller and less dramatic effect than the threat nudge group. Analysis of variance showed a significant difference in stretching time across groups ( = 26.43, =.000; η =0.44), with post-hoc tests indicating that the threat nudge group significantly outperformed both the benefit nudge and the control group in stretching duration.
One implication of these findings was that, as suggested by the health belief model, perceived threat can be a strong motivator for behavior change in the short term while perceived benefits alone may not be sufficient to drive immediate action. Practically, threat-based messaging can be particularly useful in the short term for physical activity instructors and app developers to motivate clients.
我们旨在研究基于健康信念模型的助推信息对基于威胁或基于益处的伸展运动参与度的有效性。
采用准实验设计，将参与者（N = 69）分为三组：威胁助推组，接收强调感知易感性和严重性的信息；益处助推组，接收关于伸展运动优势的信息；对照组，不接收任何信息。该研究于2024年10月至11月在韩国进行。使用健康应用程序在六周内测量参与者的伸展运动参与度，该应用程序提供伸展运动课程并跟踪记录其持续时间。
威胁助推组的伸展行为增加幅度最大，显著优于益处助推组和对照组。益处助推组有所改善，但总体效果往往比威胁助推组小且不那么显著。方差分析显示各组之间的伸展时间存在显著差异（F = 26.43，p =.000；η² = 0.44），事后检验表明威胁助推组在伸展持续时间上显著优于益处助推组和对照组。
这些发现的一个启示是，正如健康信念模型所表明的，感知威胁在短期内可能是行为改变的强大动力，而仅感知到的益处可能不足以促使立即采取行动。实际上，基于威胁的信息在短期内对体育活动教练和应用程序开发者激励客户可能特别有用。
