This study aims to evaluate the effectiveness of a web-based intervention to reduce alcohol consumption among hazardous drinkers. A two-group parallel randomized controlled trial was conducted among adults identified as hazardous drinkers according to the Alcohol Use Disorders Identification Test. The intervention delivers personalized normative feedback and some general information about alcohol. Participants can review their motivations and fears regarding reducing their alcohol intake, set individual goals and monitor their progress via a consumption diary and other tools. Within the control group, participants were provided with the same diary but could not access other services from the program. The primary outcome measure was the absolute difference in weekly alcohol intake (WAI) between baseline and 6-week follow-up. Secondary outcome measures included: relative difference in WAI; difference in excessive drinking and significant WAI reduction (decrease of 10% or more in WAI). One thousand one hundred and forty-seven people participated in the trial and 339 subjects completed it. Relative to the control group, participants in the intervention group reported a significantly greater mean absolute reduction in WAI (-3.3 versus -1.2, P = 0.03). Secondary outcomes also presented significant effects. This trial provides preliminary support to the effectiveness of this program in helping hazardous drinkers reduce their drinking, provided it is completely and regularly used.
本研究旨在评估基于网络的干预措施对减少危险饮酒者酒精摄入量的有效性。根据酒精使用障碍识别测试，对被确定为危险饮酒者的成年人进行了一项两组平行随机对照试验。该干预措施提供个性化的规范反馈以及一些关于酒精的一般信息。参与者可以回顾他们关于减少酒精摄入量的动机和恐惧，设定个人目标，并通过饮酒日记和其他工具监测自己的进展。在对照组中，参与者获得了相同的日记，但无法使用该项目的其他服务。主要结局指标是基线和6周随访之间每周酒精摄入量（WAI）的绝对差异。次要结局指标包括：WAI的相对差异；过度饮酒的差异以及WAI显著降低（WAI降低10%或更多）。1147人参与了试验，339名受试者完成了试验。与对照组相比，干预组参与者报告的WAI平均绝对降低幅度显著更大（-3.3对-1.2，P = 0.03）。次要结局也呈现出显著效果。本试验为该项目在帮助危险饮酒者减少饮酒方面的有效性提供了初步支持，前提是该项目得到充分且定期的使用。
