Many newly diagnosed cancers are associated with modifiable lifestyle behaviors, such as diet, exercise, smoking cessation, and maintaining a healthy weight. However, primary care providers rarely discuss cancer prevention behaviors with their patients.
This study aims to assess the usability, acceptability, and user engagement of the Healthier Together mobile app, which is designed to promote cancer prevention behaviors among non-Hispanic Black primary care patients, by using social networks and goal-setting theories of behavior change.
In an 8-week pilot study, we enrolled primary care patients (N=41) and provided them with a cancer prevention mobile app that allowed them to select, track, and share progress on cancer prevention goals with other users. App usability was assessed using the System Usability Scale. We assessed the app's acceptability by qualitatively analyzing open-ended responses regarding participants' overall experience with the app. We assessed participants' engagement by analyzing the built-in data capture device, which included the number of times participants checked in (out of a maximum of 8) during the study.
The mean age of the 41 participants was 51 years (SD 12), and 76% (31/41) were women. App use data were captured from all participants, and 83% (34/41) completed the exit survey and interview. The mean System Usability Scale score was 87 (SD 12; median 90; IQR 78-95). The analysis of open-ended responses revealed several key themes, and participants complemented the app's ease of use and health behavior-promoting features while also commenting on the need for more feedback and social interactions through the app. On average, participants checked in 5.7 times (SD 2.7) out of 8 possible opportunities. Of the 41 participants, 76% (31/41) checked in during at least 4 of the 8 weeks. Secondary analyses revealed that participants often accomplished their set goals (mean 5.1, SD 2.7) for each week. The qualitative analysis of comments given by participants within the app after each weekly check-in revealed several themes on how the app assisted participants in behavioral change, highlighting that some participants created exercise programs, ate healthier foods, lost a significant amount of weight, and stopped smoking during this study.
The implementation of a mobile cancer prevention goal-setting app in a primary care setting was feasible, and the app achieved high usability, acceptability, and engagement among participants. User feedback revealed an influence on health behaviors. These findings suggest the promise of the Healthier Together app in facilitating behavioral change to reduce cancer risk among non-Hispanic Black primary care patients.
许多新诊断出的癌症与可改变的生活方式行为有关，如饮食、运动、戒烟和保持健康体重。然而，初级保健提供者很少与患者讨论癌症预防行为。
本研究旨在评估“共同更健康”移动应用程序的可用性、可接受性和用户参与度，该应用程序旨在通过使用社交网络和行为改变的目标设定理论，促进非西班牙裔黑人初级保健患者的癌症预防行为。
在一项为期8周的试点研究中，我们招募了初级保健患者（N = 41），并为他们提供了一款癌症预防移动应用程序，该程序允许他们选择、跟踪癌症预防目标并与其他用户分享进展。使用系统可用性量表评估应用程序的可用性。我们通过定性分析关于参与者对应用程序总体体验的开放式回答来评估应用程序的可接受性。我们通过分析内置数据捕获设备来评估参与者的参与度，该设备包括参与者在研究期间签到的次数（最多8次）。
41名参与者的平均年龄为51岁（标准差12），76%（31/41）为女性。从所有参与者那里获取了应用程序使用数据，83%（34/41）完成了退出调查和访谈。系统可用性量表的平均得分为87（标准差12；中位数90；四分位距78 - 95）。对开放式回答的分析揭示了几个关键主题，参与者称赞了应用程序的易用性和促进健康行为的功能，同时也评论了通过该应用程序获得更多反馈和社交互动的必要性。平均而言，参与者在8次可能的机会中签到5.7次（标准差2.7）。在41名参与者中，76%（31/41）在8周中的至少4周进行了签到。二次分析显示，参与者通常每周都能完成他们设定的目标（平均5.1个，标准差2.7）。对参与者在每周签到后在应用程序内给出的评论进行定性分析，揭示了几个关于该应用程序如何帮助参与者改变行为的主题，突出表明一些参与者在本研究期间制定了锻炼计划、吃更健康的食物、减掉了大量体重并戒烟。
在初级保健环境中实施移动癌症预防目标设定应用程序是可行的，该应用程序在参与者中实现了高可用性、可接受性和参与度。用户反馈显示对健康行为有影响。这些发现表明“共同更健康”应用程序在促进行为改变以降低非西班牙裔黑人初级保健患者的癌症风险方面具有前景。
