We designed an mHealth application (app) user interface (UI) prototype informed by participatory design sessions, persuasive systems design (PSD) principles, and Lorig and Holman's self-management behavior framework to support self-management activities of Hispanic informal dementia caregivers and assessed their perceptions and preferences regarding features and functions of the app.
Our observational usability study design employed qualitative methods and forced choice preference assessments to identify: (1) the relationship between user preferences for UI features and functions and PSD principles and (2) user preferences for UI design features and functions and app functionality. We evaluated 16 pairs of mHealth app UI prototype designs. Eight paper-based paired designs were used to assess the relationship between PSD principles and caregiver preferences for UI features and functions to support self-management. An Apple iPad WIFI 32GB was used to display another 8 paired designs and assess caregiver preferences for UI functions to support the self-management process.
Caregivers preferred an app UI with features and functions that incorporated a greater number of PSD principles and included an infographic to facilitate self-management. Moreover, caregivers preferred a design that did not depend on manual data entry, opting instead for functions such as drop-down list, drag-and-drop, and voice query to prioritize, choose, decide, and search when performing self-management activities.
Our assessment approaches allowed us to discern which UI features, functions, and designs caregivers preferred. The targeted application of PSD principles in UI designs holds promise for supporting personalized problem identification, goal setting, decision-making, and action planning as strategies for improving caregiver self-management confidence.
我们设计了一个移动健康应用程序（app）用户界面（UI）原型，该原型参考了参与式设计会议、说服系统设计（PSD）原则以及洛里格和霍尔曼的自我管理行为框架，以支持西班牙裔非正式痴呆症护理人员的自我管理活动，并评估他们对该应用程序的功能和特性的看法及偏好。
我们的观察性可用性研究设计采用定性方法和强制选择偏好评估，以确定：（1）用户对UI功能和特性的偏好与PSD原则之间的关系；（2）用户对UI设计功能和特性以及应用程序功能的偏好。我们评估了16对移动健康应用程序UI原型设计。八对纸质配对设计用于评估PSD原则与护理人员对支持自我管理的UI功能和特性的偏好之间的关系。一台苹果iPad WIFI 32GB用于展示另外八对设计，并评估护理人员对支持自我管理过程的UI功能的偏好。
护理人员更喜欢具有更多PSD原则功能和特性的应用程序UI，并且该UI包含一个信息图表以促进自我管理。此外，护理人员更喜欢不依赖手动数据输入的设计，而是选择诸如下拉列表、拖放和语音查询等功能，以便在进行自我管理活动时对优先级、选择、决策和搜索进行排序。
我们的评估方法使我们能够辨别护理人员更喜欢哪些UI功能、特性和设计。在UI设计中有针对性地应用PSD原则有望支持个性化问题识别、目标设定、决策和行动计划，作为提高护理人员自我管理信心的策略。
