The efficacy of alcohol reduction applications is variable, and the underlying factors are largely unknown. The aim of this study is threefold: evaluate the relationship between user engagement and intervention efficacy, investigate the efficacy of the different functions applied, and investigate the efficacy of the intervention application compared to control groups.
A randomized controlled trial will be conducted to determine the efficacy of a newly developed smartphone application compared to the controls in reducing alcohol consumption at a 30, 60, 90, 120, 150, and 180 days follow-up. Hazardous drinkers, aged 18 years or older, will be recruited through web articles and will be randomized (blinded to their allocation), to receive one of the two versions of the application (educational or control application) for 30 days, or will be allocated to a wait-list control group. Function usage times will be recorded on a single-user level to determine the association between application usage and efficacy.
Data collection will be completed by July 2020, and follow-up will be completed by January 2021.
The evaluation of intervention efficacy as a function of user behavior will hopefully contribute to the science of developing more efficient alcohol intervention applications in the future.
减少饮酒应用程序的效果各不相同，其潜在因素在很大程度上尚不清楚。本研究旨在评估以下三个方面：用户参与度与干预效果之间的关系，不同功能的应用效果，以及干预应用程序与对照组的效果。
将开展一项随机对照试验，以确定与对照组相比，一种新开发的智能手机应用程序在 30、60、90、120、150 和 180 天随访时减少饮酒量的效果。通过网络文章招募年龄在 18 岁或以上的危险饮酒者，并对其进行随机分组（对其分配情况进行盲法处理），分别接受应用程序的两种版本（教育版或对照组）30 天，或分配到等候名单对照组。将记录单个用户层面的功能使用时间，以确定应用程序使用与效果之间的关联。
数据收集将于 2020 年 7 月完成，随访将于 2021 年 1 月完成。
对干预效果作为用户行为的函数进行评估，有望有助于未来开发更有效的酒精干预应用程序。
