Despite a growing number of clinical-intervention studies of mobile applications for diabetes self-management, details of participants' engagement with the intervention tools and of usability and feasibility issues are seldom reported. The Few Touch application is a mobile-phone-based self-management system for people with Type 2 diabetes mellitus (T2DM) developed by involving patient-users in design processes from an early phase to a long-term trial. An improved version was tested in a five-month trial by 11 individuals either with T2DM or at high risk of T2DM. Results showed clearer correlations between usage and perceived usefulness among these individuals compared with those involved in the design process. However, feedback on usability issues was mostly consistent between the two trials. This study therefore confirmed: 1) the value of including patient-users not only in design-concept development but also in a long-term trial to identify as many factors critical to usability and usage as possible, and 2) the importance of reflecting their feedback in design iterations to minimize the number of critical factors.
尽管针对糖尿病自我管理的移动应用程序的临床干预研究数量不断增加，但很少有研究报告参与者与干预工具的互动细节以及可用性和可行性问题。“Few Touch”应用程序是一款基于手机的2型糖尿病（T2DM）患者自我管理系统，该系统在设计过程中从早期阶段到长期试验都让患者用户参与其中。一个改进版本在一项为期五个月的试验中由11名患有T2DM或有T2DM高风险的个体进行了测试。结果显示，与参与设计过程的个体相比，这些个体的使用情况与感知有用性之间的相关性更明显。然而，两次试验中关于可用性问题的反馈大多一致。因此，本研究证实了：1）让患者用户不仅参与设计概念开发，还参与长期试验以尽可能确定许多对可用性和使用至关重要的因素的价值；2）在设计迭代中反映他们的反馈以尽量减少关键因素数量的重要性。
