Binge drinking, which is linked to various immediate and long-term negative outcomes, is highly prevalent among US college students. Behavioral interventions delivered via mobile phones have a strong potential to help decrease the hazardous effects of binge drinking by promoting safer drinking behaviors.
This study aims to evaluate the preliminary efficacy of bhoos, a novel smartphone app designed to promote safer drinking behaviors among US college students. The app offers on-demand educational content about safer alcohol use, provides dynamic feedback as users log their alcohol consumption, and includes an interactive drink tracker that estimates blood alcohol content in real time.
The bhoos app was tested in 2 independent pre-post studies each lasting 4 weeks, among US college students aged 18-35 years. The primary outcome in both trials was students' self-reported confidence in using protective behavioral strategies related to drinking, with self-reported frequency of alcohol consumption over the past month examined as a secondary outcome.
In study 1, bhoos was associated with increased confidence in using protective behavioral strategies. Students also endorsed the high usability of the app and reported acceptable levels of engagement. Study 2 replicated findings of increased confidence in using protective behavioral strategies, and demonstrated a reduction in the self-reported frequency of alcohol consumption.
Bhoos is a personalized, accessible, and highly scalable digital intervention with a strong potential to effectively address alcohol-related behaviors on college campuses.
狂饮与各种即时和长期的负面后果相关，在美国大学生中极为普遍。通过手机进行的行为干预具有很大潜力，可通过促进更安全的饮酒行为来帮助减少狂饮的有害影响。
本研究旨在评估bhoos的初步疗效，bhoos是一款旨在促进美国大学生更安全饮酒行为的新型智能手机应用程序。该应用程序提供有关更安全饮酒的按需教育内容，在用户记录饮酒量时提供动态反馈，并包括一个交互式饮酒追踪器，可实时估计血液酒精含量。
bhoos应用程序在美国18 - 35岁的大学生中进行了2项独立的前后对照研究，每项研究持续4周。两项试验的主要结果是学生自我报告的使用与饮酒相关的保护性行为策略的信心，过去一个月自我报告的饮酒频率作为次要结果进行检查。
在研究1中，bhoos与使用保护性行为策略的信心增加相关。学生们还认可该应用程序的高可用性，并报告了可接受的参与度水平。研究2重复了使用保护性行为策略信心增加的结果，并表明自我报告的饮酒频率有所降低。
Bhoos是一种个性化、易于使用且具有高度可扩展性的数字干预措施，具有有效解决大学校园与酒精相关行为的强大潜力。
