Abstract:Introduction: An unhealthy lifestyle such as insufficient physical inactivity, smoking, obesity, and an unhealthy diet, may increase the risk of ischemic stroke and other cardiovascular diseases. Stimulating a healthy lifestyle can therefore be an effective way to reduce the risk of vascular complications after a Transient Ischemic Attack (TIA) or stroke and may play a crucial role in preventing death of these patients. The aim of this study is the development of a low-fidelity (Lo-Fi) prototype of an eHealth application that supports patients with their lifestyle changes after a TIA or stroke. Method: The study consists of three stages: development of requirements, prototype design, and evaluation. The formulated requirements are based on previous studies by Al-Dhahir (2015) and De Jong (2015) and have been translated into a Lo-Fi prototype. In order to develop the prototype, the transtheoretical model, the Roadmap of the Center for eHealth Research (CeHRes Roadmap) and Persuasive Systems Design (PSD) model have been used. Seven patients who had a TIA or ischemic stroke evaluated the prototype, by using thinkaloud method and semi-structured interviews. Results: The requirements analysis showed that the eHealth lifestyle intervention should give clear content information, practical advice, and tips. It should also deliver tailored feedback to motivate the user. In addition, eHealth lifestyle intervention should provide information based on scientific and reliable information and, in addition, give simple information through verbal and non-verbal communication. eHealth lifestyle intervention should be user-friendly and easy to navigate without much help. Based on the requirements and the literature, a prototype has been developed that guides the user. The prototype has four components, namely screening, information and hints, food diary, and setting goals. Formative evaluation showed that the participants experienced all components of the prototype to be useable, comprehensible and motivating, except the food diary. The food diary was experienced relevant, but not practically applicable in daily life. Conclusion: The prototype for the promotion of lifestyle is well appreciated by patients. They see it as useable, understandable, and motivating. They are open to receive information through the virtual coach 'Avatar' and videos. Readability (font), comprehensiveness, and reliability of information were found to be important for these patients. The eHealth lifestyle intervention should not only be functional, but also be designed aesthetically.
