背景:年轻人中的高风险饮酒经常发生在同龄人也饮酒的情况下。高风险饮酒情况可能由与饮酒有主要关联的特定社交网络成员组成。诸如生态瞬时评估(EMA)之类的细粒度方法在研究实时社会影响方面越来越受欢迎,但是使用这些方法的研究完全依赖于参与者的自我报告。使用基于蓝牙的技术来检测实时交互的对等存在的被动指标有可能帮助开发即时干预措施。
目的:本研究旨在研究使用基于蓝牙的传感器和智能手机应用程序来测量现实世界饮酒情况下的社交接触的可行性和可接受性。
方法:将从社区招募大量饮酒并报告社交饮酒的年轻人(N=20)参加为期3周的EMA研究。使用社交网络采访,索引参与者将识别并招募他们的3个朋友携带蓝牙信标。参与者将在自己的个人Android设备上完成一系列EMA报告,包括随机报告;早上报告;第一杯报告;和信号报告,其在检测到由对等参与者携带的信标之后被触发。EMA将评估酒精使用和社会环境的特征,包括谁在附近,谁在喝酒。对于有关同伴接近度和同伴饮酒的项目,将向参与者提供定制的对等者列表。关于研究方案的反馈将通过每周与指标和同伴参与者联系来确定。然后在研究结束时进行定性访谈。我们会研究招聘的可行性和可接受性,参与者和同龄人的注册,和保留。可行性将使用合格指标来确定,招生,和招聘。可接受性将通过参与者注册和保留来确定,协议合规性,和参与者报告的可接受性措施。同行参与者的可行性和可接受性将由入学率通知,注册延迟,遵守携带信标,以及自我报告的遵守或不遵守信标程序的原因。最后,有关同伴接近度和同伴饮酒的EMA数据将支持同伴选择过程的有效性。
结果:参与者招募于2023年2月开始,注册于2023年12月完成。结果将在2025年报告。
结论:该协议使我们能够检查基于蓝牙的传感器的可行性和可接受性,以检测索引参与者及其朋友之间的社交联系,包括现实世界饮酒情况下的社交互动。这项研究的数据将通过提供有关高风险社会环境的个性化反馈并提醒个人他们处于潜在的不安全状况,为寻求在自然环境中饮酒的及时适应性干预措施提供信息。

BACKGROUND: High-risk alcohol consumption among young adults frequently occurs in the presence of peers who are also drinking. A high-risk drinking situation may consist of particular social network members who have a primary association with drinking. Fine-grained approaches such as ecological momentary assessment (EMA) are growing in popularity for studying real-time social influence, but studies using these approaches exclusively rely on participant self-report. Passive indicators of peer presence using Bluetooth-based technology to detect real-time interactions have the potential to assist in the development of just-in-time interventions.
OBJECTIVE: This study seeks to examine the feasibility and acceptability of using a Bluetooth-based sensor and smartphone app to measure social contact in real-world drinking situations.
METHODS: Young adults (N=20) who drink heavily and report social drinking will be recruited from the community to participate in a 3-week EMA study. Using a social network interview, index participants will identify and recruit 3 of their friends to carry a Bluetooth beacon. Participants will complete a series of EMA reports on their own personal Android devices including random reports; morning reports; first-drink reports; and signal-contingent reports, which are triggered following the detection of a beacon carried by a peer participant. EMA will assess alcohol use and characteristics of the social environment, including who is nearby and who is drinking. For items about peer proximity and peer drinking, a customized peer list will be presented to participants. Feedback about the study protocol will be ascertained through weekly contact with both index and peer participants, followed by a qualitative interview at the end of the study. We will examine the feasibility and acceptability of recruitment, enrollment of participants and peers, and retention. Feasibility will be determined using indexes of eligibility, enrollment, and recruitment. Acceptability will be determined through participant enrollment and retention, protocol compliance, and participant-reported measures of acceptability. Feasibility and acceptability for peer participants will be informed by enrollment rates, latency to enrollment, compliance with carrying the beacon, and self-reported reasons for compliance or noncompliance with beacon procedures. Finally, EMA data about peer proximity and peer drinking will support the validity of the peer selection process.
RESULTS: Participant recruitment began in February 2023, and enrollment was completed in December 2023. Results will be reported in 2025.
CONCLUSIONS: The protocol allows us to examine the feasibility and acceptability of a Bluetooth-based sensor for the detection of social contact between index participants and their friends, including social interactions during real-world drinking situations. Data from this study will inform just-in-time adaptive interventions seeking to address drinking in the natural environment by providing personalized feedback about a high-risk social context and alerting an individual that they are in a potentially unsafe situation.
