Abstract

Objective: The objective of the current study was to develop and evaluate a persuasive decision-support aiming at reducing pre-hospital delay and increasing ambulance service use for patients who suffer from a recurrent myocardial infarction. Materials and methods: The system was developed as a prototype mobile application for smartphones. The system was evaluated by four end-users with previous experience of myocardial infarction. The user tests were complemented with cognitive walkthroughs and heuristic evaluation. Results: A total of 14 persuasive design principles were used to guide the design of the system. The usability was regarded as high with an average score of 82 on the System Usability Scale. The users reported that they found the system highly persuasive. Conclusions: User-centered design together with persuasive design principles through iterative testing and development has resulted in a prototype app with potential to improve patients’ care-seeking behavior. The content in the prototype will be further evaluated before it is integrated in educational interventions.

一个有说服力的移动应用程序的试点评估，以改变复发性心肌梗死期间个人的行为

目的:当前研究的目的是开发和评估一种有说服力的决策支持，旨在减少院前延误，增加复发性心肌梗死患者的救护车服务使用。材料和方法:该系统是作为智能手机的原型移动应用程序开发的。该系统由四位具有心肌梗死经验的最终用户进行评估。用户测试辅以认知演练和启发式评估。结果:共采用14条说服设计原则指导系统设计。可用性被认为是高的，在系统可用性量表上平均得分为82分。用户报告说，他们发现这个系统非常有说服力。结论:以用户为中心的设计和有说服力的设计原则，通过反复测试和开发，形成了一个有潜力改善患者求医行为的原型应用。在将原型中的内容纳入教育干预之前，将对其进行进一步评估。
