Mobile health applications have been widely adopted among breast cancer survivors for disease management; however, their use specifically for the prevention of breast cancer-related lymphedema (BCRL) remains sparse. This study is aimed at developing a WeChat-based intervention program for the prevention of BCRL based on the common-sense model (CSM).
This study was designed based on intervention mapping. First, a longitudinal investigation was conducted to determine the predictive effect of illness perception on BCRL prevention behaviors among breast cancer survivors. An intervention program was then constructed based on the CSM and longitudinal results. Finally, a WeChat mini-program was developed, and 15 patients were recruited to test its usability and user satisfaction through usability tests based on typical tasks and the Post-Study System Usability Questionnaire (PSSUQ), respectively.
The longitudinal study revealed that identity, personal control, illness coherence, and behavioral and physical factors in the causes dimension could positively predict prevention behaviors, whereas treatment control and uncontrollable factors exhibited negative predictive effects. This study then developed an individualized intervention program and a WeChat mini-program (named "Nantian e-Care") consisting of five modules: "resources," "questionnaires," "homepage," "consultation," and "personal center." Patients could read BCRL-related educational content, watch functional exercise videos, self-measure arm circumference, and consult questions. The five-task completion rates were 80.00 ~ 100.00%, the average completion time was 9.47 ~ 33.31 s, and the scores of PSSUQ were greater than 5 points (full score 7 points).
This study proposed a feasible intervention program for the prevention of BCRL and developed a customized WeChat mini-program with high usability and user satisfaction.

移动健康应用程序已在乳腺癌幸存者中广泛用于疾病管理；然而，其专门用于预防乳腺癌相关淋巴水肿（BCRL）的情况仍然很少。本研究旨在基于常识模型（CSM）开发一个基于微信的BCRL预防干预项目。
本研究基于干预映射进行设计。首先，进行了一项纵向调查，以确定疾病认知对乳腺癌幸存者BCRL预防行为的预测作用。然后根据CSM和纵向研究结果构建了一个干预项目。最后，开发了一个微信小程序，并招募了15名患者，分别通过基于典型任务的可用性测试和研究后系统可用性问卷（PSSUQ）来测试其可用性和用户满意度。
纵向研究表明，病因维度中的身份认同、个人控制、疾病连贯性以及行为和身体因素可正向预测预防行为，而治疗控制和不可控因素则呈现负向预测作用。本研究随后开发了一个个性化干预项目和一个微信小程序（名为“南天e关爱”），该小程序由五个模块组成：“资源”“问卷”“主页”“咨询”和“个人中心”。患者可以阅读与BCRL相关的教育内容、观看功能锻炼视频、自行测量手臂周长并咨询问题。五项任务的完成率为80.00%至100.00%，平均完成时间为9.47至33.31秒，PSSUQ得分大于5分（满分7分）。
本研究提出了一个可行的BCRL预防干预项目，并开发了一个具有高可用性和用户满意度的定制微信小程序。
