摘要

导言:在线干预已成为解决健康问题(尤其是肥胖症)的创新解决方案,同时在最近的 COVID-19 大流行中,最大限度地减少了面对面互动的必要性。在网络应用程序中设计和开发适当的在线干预模块迫在眉睫。本研究旨在描述在线食堂操作员、家长和教师(CoPT Nutri Trail)模块的设计过程和可用性,以用于即将开展的校本肥胖症干预活动。材料与方法:设计方法包括四个阶段:内容开发、设计、网络应用程序开发和可用性测试。该网络应用程序旨在为教师、家长和食堂经营者提供个性化的使用方法,从而为儿童营造健康的环境。包括教师、营养学家和信息技术专业人员在内的 13 位专家参与了可用性测试。结果:所有专家都认为网络应用程序的设计符合目标用户的要求,只需在图形设计、语言和信息元素方面稍作改进。所有界面元素的可用性 alpha 得分为 68.2%至 86.6%,介于好和非常好之间,因此网络应用工具是可以接受的。内容验证指数表明有效性水平良好(从 0.83 到 1.00)。结论:CoPT Nutri Trail 网络应用程序已准备就绪,可以作为肥胖症的校本干预措施推出。

Design and Usability Testing of a Web-Based Intervention Module for Obesity: CoPT Nutri Trail
INTRODUCTION: Online interventions have emerged as innovative solutions to address health issues, notably obesity, while minimizing the necessity for in-person interactions during the recent COVID-19 pandemic. There is urgency in designing and developing an appropriate online intervention module within a web-based application. This study aims to describe the design process and usability of the online Canteen Operators, Parents, and Teachers (CoPT Nutri Trail) module for an upcoming school-based obesity intervention. MATERIALS AND METHODS: The design methodology consists of four phases: content development, design, web app development, and usability testing. The web application was designed to personalize usage for teachers, parents, and canteen operators to foster healthy environments for children. Thirteen experts, including teachers, nutritionists, and IT professionals, participated in the usability testing. RESULTS: All experts agreed that the design of the web application met the requirements of target users, requiring slight improvements in graphic design, language, and information elements. The web application tool was found acceptable, as the usability of alpha scores for all interface elements ranged from 68.2% to 86.6%, falling between good and very good scores. The content validation indices indicate good levels of validity (ranging from 0.83 to 1.00). CONCLUSION: The CoPT Nutri Trail web application is ready to be launched as a school-based intervention for obesity.
