We report findings from two feasibility studies with persons with SCI that aimed to leverage social support to increase PA: a two-week study with nine participants and a four-week study with six participants.
We recruited a total of 17 participants across two phases (10 participants in Phase 1 and seven participants in Phase 2). In dyads, participants used a smartphone-smartwatch application that we iteratively developed based on participant feedback. The application delivered just-in-time support based on measured PA and encouraged reciprocal self-disclosure to increase closeness within dyads.
Participants found the delivery of messages during detected PA to be motivational. Some liked automatically sharing tracked PA with others and did not have privacy concerns about doing so, and most preferred exchanging real-time messages more than context- or activity-triggered messages. Participants also expressed that feeling connected to their partner increased motivation to engage in PA.
Participants expressed that they liked being able to connect with individuals with shared life experience to exchange encouraging messages. There are, however, challenges that need to be addressed before a large-scale deployment of this technology, including user concerns about automatically detected activity.
我们报告了两项针对脊髓损伤患者的可行性研究结果，这些研究旨在利用社会支持来增加身体活动（PA）：一项为期两周、有9名参与者的研究和一项为期四周、有6名参与者的研究。
我们分两个阶段共招募了17名参与者（第一阶段10名参与者，第二阶段7名参与者）。参与者两两一组，使用一款我们根据参与者反馈反复开发的智能手机-智能手表应用程序。该应用程序根据测量的身体活动提供即时支持，并鼓励相互自我表露，以增加两人组内的亲密感。
参与者发现，在检测到身体活动期间发送的信息具有激励作用。一些人喜欢自动与他人分享跟踪到的身体活动，并且对此没有隐私方面的担忧，而且大多数人更喜欢交换实时信息，而不是情境或活动触发的信息。参与者还表示，与伴侣建立联系的感觉增加了参与身体活动的动力。
参与者表示，他们喜欢能够与有共同生活经历的人建立联系，以交流鼓励信息。然而，在大规模部署这项技术之前，还有一些挑战需要解决，包括用户对自动检测活动的担忧。
