妇女、婴儿和儿童特别补充营养援助计划 (WIC) 是一项联邦营养计划，为低收入妇女、婴儿和 5 岁以下儿童提供营养食品、教育和医疗保健转介。尽管 WIC 与每个参与者类别的积极健康结果相关，但诊所和购物层面仍需要现代化和效率，以提高计划满意度和参与率。电子福利转移 (EBT)、在线营养教育和移动应用程序等新技术可以为参与者提供改善 WIC 体验的机会。这项形成性研究应用以用户为中心的设计原则，为参与 WIC 计划的低收入家庭提供移动应用程序功能的布局和优先级。为了确定并优先考虑理想的应用程序功能，WIC 注册儿童的看护者 (N=22) 参加了个人半结构化访谈和卡片分类活动。采访内容被逐字记录，并使用不断的主题比较分析进行分析。每个参与者对应用程序功能进行排名并自然分组。计算排名的总和和平均值，以了解用户优先考虑哪些功能。根据参与者的描述对特征的自然分组进行标记。自然分组侧重于以下类别：诊所/预约、购物/商店、教育/评估、位置和食谱/食物。采访的主题对排名活动的结果进行了三角测量。优先考虑的应用程序功能是余额检查、项目扫描仪和预约安排。讨论和排名的其他应用程序功能包括预约提醒、营养培训和测验、购物清单、诊所和商店定位器、食谱库、产品计算器和饮食偏好/过敏。本研究展示了以用户为中心的设计流程如何帮助参与 WIC 的低收入家庭开发应用程序，从而为应用程序功能和用户界面的有效设计提供信息。
The Special Supplemental Nutrition Assistance Program for Women, Infants, and Children (WIC) is a federal nutrition program that provides nutritious food, education, and health care referrals to low-income women, infants, and children up to the age of 5 years. Although WIC is associated with positive health outcomes for each participant category, modernization and efficiency are needed at the clinic and shopping levels to increase program satisfaction and participation rates. New technologies, such as electronic benefits transfer (EBT), online nutrition education, and mobile apps, can provide opportunities to improve the WIC experience for participants. This formative study applies user-centered design principles to inform the layout and prioritization of features in mobile apps for low-income families participating in the WIC program. To identify and prioritize desirable app features, caregivers (N=22) of the children enrolled in WIC participated in individual semistructured interviews with a card sorting activity. Interviews were transcribed verbatim and analyzed using constant comparative analysis for themes. App features were ranked and placed into natural groupings by each participant. The sum and average of the rankings were calculated to understand which features were prioritized by the users. Natural groupings of features were labeled according to participant descriptions. Natural groupings focused on the following categories: clinics/appointments, shopping/stores, education/assessments, location, and recipes/food. Themes from the interviews triangulated the results from the ranking activity. The priority app features were balance checking, an item scanner, and appointment scheduling. Other app features discussed and ranked included appointment reminders, nutrition training and quizzes, shopping lists, clinic and store locators, recipe gallery, produce calculator, and dietary preferences/allergies. This study demonstrates how a user-centered design process can aid the development of an app for low-income families participating in WIC to inform the effective design of the app features and user interface.
