Mapping of feedback/comment to dimensions.

BackgroundLimited studies have developed a mobile phone-based application that supports Asynchronous Video Observed Therapy (A-VOT) for Tuberculosis (TB) program. This study aimed to design, develop, and assess MyTBCompanion, a mobile phone-based digital health intervention to support A-VOT for TB management and care among low-income patients in Malaysia and Indonesia.MethodsMyTBCompanion was designed and developed under a partnership involving experts in information technology, respiratory disease, and linguistics. Pre and Post-test surveys were done to assess feedback on the existing TB strategies (Direct Observed Therapy (DOT) and/or VOT) and the usability of the tested A-VOT strategy using MyTBCompanion. We collected data on the patient’s age, education level, current treatment strategy, and statements measuring four MyTBCompanion components: Engagement (how interesting, customizable, interactive and well-targeted to an audience an app is), Functionality (ease of use, app design, navigation), Aesthetic (the graphic design, overall visual appeal, color scheme, and stylistic consistency) and Information (content accuracy and relevance). The Mann-Whitney U test was performed for group comparisons, with results considered significant at p ResultsIn total, 49 patients with TB were recruited from Malaysia (n = 29) and Indonesia (n = 20). Most participants in both countries were 20–40 years old. Indonesian participants mainly had tertiary education (11/20, 55.0%), whereas most had secondary education level in Malaysia (17/29, 58.6%). Most Malaysian participants (19/29, 65.5%) were using VOT through WhatsApp, with fewer (10/29, 34.5%) using DOT. All participants from Indonesia (20/20, 100%) were using the DOT strategy. Overall, compared to the existing strategies, a higher mean agreement score was observed for MyTBCompanion, with Information scoring the highest agreement (4.57/5.0), followed by Engagement (4.53/5.0), Functionality (4.51/5.0) and Aesthetic (4.49/5.0).ConclusionFindings suggest an overall good agreement on the usability of A-VOT strategy using MyTBCompanion in terms of engagement, functionality, information and aesthetics, with many indicating their willingness to recommend it to others, marking an encouraging milestone in the app’s development.

背景 目前针对结核病（Tuberculosis, TB）管理，支持异步视频监督治疗（Asynchronous Video Observed Therapy, A-VOT）的手机应用相关研究较为匮乏。
本研究旨在设计、开发并评估MyTBCompanion——一款基于移动设备的数字健康干预工具，用于为马来西亚与印度尼西亚的低收入结核病患者提供A-VOT支持，以辅助结核病的诊疗与照护工作。

方法 MyTBCompanion由信息技术、呼吸病学与语言学领域的专家合作完成设计与开发。本研究采用前后测问卷，分别评估受试者对现有结核病诊疗策略（直接监督治疗（Direct Observed Therapy, DOT）和/或VOT）的反馈，以及基于MyTBCompanion的A-VOT策略的可用性。研究收集了受试者的年龄、受教育程度、当前治疗方案，以及针对MyTBCompanion四大核心维度的评价数据：参与度（应用的趣味性、可定制性、交互性与受众针对性）、功能实用性（易用性、应用界面设计、导航便捷性）、美学体验（图形设计、整体视觉吸引力、配色方案与风格统一性）与信息内容（内容准确性与相关性）。采用曼-惠特尼U检验进行组间比较，以p值作为结果具有统计学显著性的判定标准。

结果 本研究共招募49名结核病患者，其中马来西亚29例，印度尼西亚20例。两国受试者的年龄大多集中在20至40岁区间。印度尼西亚受试者以高等教育学历为主（11/20，55.0%），而马来西亚受试者则以中等教育学历居多（17/29，58.6%）。马来西亚受试者中多数（19/29，65.5%）通过WhatsApp使用VOT，仅少数（10/29，34.5%）采用DOT策略；印度尼西亚所有受试者（20/20，100%）均采用DOT策略。总体而言，相较于现有治疗策略，受试者对MyTBCompanion的平均认可评分更高，其中信息内容维度评分最高（4.57/5.0），其次为参与度（4.53/5.0）、功能实用性（4.51/5.0）与美学体验（4.49/5.0）。

结论 研究结果表明，受试者对基于MyTBCompanion的A-VOT策略在参与度、功能实用性、信息内容与美学体验层面的可用性整体认可度良好，多数受试者表示愿意向他人推荐该应用，这标志着该应用开发进程中取得了令人鼓舞的阶段性成果。
