Mobile health (mHealth) interventions have the potential to deliver longitudinal support to users outside of episodic clinical encounters. We performed a qualitative substudy to assess the acceptability of a text message-based mHealth intervention designed to increase and sustain physical activity in cardiac rehabilitation enrollees.
Semistructured interviews were conducted with intervention arm participants of a randomized controlled trial delivered to low- and moderate-risk cardiac rehabilitation enrollees. Interviews explored participants' interaction with the mobile application, reflections on tailored text messages, integration with cardiac rehabilitation, and opportunities for improvement. Transcripts were thematically analyzed using an iteratively developed codebook. Sample size consisted of 17 participants with mean age of 65.7 (SD 8.2) years; 29% were women, 29% had low functional capacity, and 12% were non-White. Four themes emerged from interviews: engagement, health impact, personalization, and future directions. Participants engaged meaningfully with the mHealth intervention, finding it beneficial in promoting increased physical activity. However, participants desired greater personalization to their individual health goals, fitness levels, and real-time environment. Generally, those with lower functional capacity and less experience with exercise were more likely to view the intervention positively. Finally, participants identified future directions for the intervention including better incorporation of exercise physiologists and social support systems.
Cardiac rehabilitation enrollees viewed a text message-based mHealth intervention favorably, suggesting the potentially high usefulness of mHealth technologies in this population. Addressing participant-identified needs on increased user customization and inclusion of clinical and social support is crucial to enhancing the effectiveness of future mHealth interventions.

移动健康 (mHealth) 干预措施有可能在非偶发性临床就诊之外为用户提供长期支持。我们进行了一项定性子研究，以评估一种基于短信的 mHealth 干预措施的可接受性，该措施旨在增加和维持心脏康复患者的身体活动。
对一项随机对照试验的干预组参与者进行了半结构化访谈，该试验针对低风险和中风险的心脏康复患者进行。访谈探讨了参与者与移动应用程序的互动、对定制短信的思考、与心脏康复的整合以及改进的机会。使用迭代开发的代码簿对转录本进行主题分析。样本量由 17 名参与者组成，平均年龄为 65.7（8.2）岁；29%为女性，29%功能能力较低，12%为非白人。访谈中出现了四个主题：参与、健康影响、个性化和未来方向。参与者与 mHealth 干预措施进行了有意义的互动，发现它有利于促进身体活动的增加。然而，参与者希望根据自己的个人健康目标、健身水平和实时环境对其进行更个性化的设置。一般来说，功能能力较低和运动经验较少的参与者更有可能对干预持积极态度。最后，参与者确定了干预措施的未来方向，包括更好地纳入运动生理学家和社会支持系统。
心脏康复患者对基于短信的 mHealth 干预措施持积极看法，这表明 mHealth 技术在该人群中具有很高的实用性。满足参与者对增加用户定制化以及纳入临床和社会支持的需求，对于提高未来 mHealth 干预措施的效果至关重要。
