Alcohol misuse is higher in the UK Armed Forces than in the general population. Previous research has shown that interventions delivered via smartphones are efficacious in promoting self-monitoring of alcohol use, have utility in reducing alcohol consumption, and have a broad reach.
This single-blinded randomized controlled trial (RCT) aims to assess the efficacy of a 28-day brief alcohol intervention delivered via a smartphone app (Drinks:Ration) in reducing weekly self-reported alcohol consumption between baseline and 3-month follow-up among veterans who drink at a hazardous or harmful level and receive or have received support for mental health symptoms in a clinical setting.
In this two-arm, single-blinded RCT, a smartphone app that includes interactive features designed to enhance participants' motivation and personalized messaging is compared with a smartphone app that provides only government guidance on alcohol consumption. The trial will be conducted in a veteran population that has sought help through Combat Stress, a UK veteran's mental health charity. Recruitment, consent, and data collection will be carried out automatically through the Drinks:Ration platform. The primary outcome is the change in self-reported weekly alcohol consumption between baseline (day 0) and 3-month follow-up (day 84) as measured using the Time-Line Follow back for Alcohol Consumption. Secondary outcome measures include (1) change in the baseline to 3-month follow-up (day 84) Alcohol Use Disorder Identification Test score and (2) change in the baseline to 3-month follow-up (day 84) World Health Organization Quality of Life-BREF score to assess the quality of adjusted life years. Process evaluation measures include (1) app use and (2) usability ratings as measured by the mHealth App Usability Questionnaire. The primary and secondary outcomes will also be reassessed at the 6-month follow-up (day 168) to assess the longer-term benefits of the intervention, which will be reported as a secondary outcome.
The study will begin recruitment in October 2020 and is expected to require 12 months to complete. The study results will be published in 2022.
This study assesses whether a smartphone app is efficacious in reducing self-reported alcohol consumption in a veteran population that has sought help through Combat Stress using personalized messaging and interactive features. This innovative approach, if successful, may provide a means to deliver a low-cost health promotion program that has the potential to reach large groups, in particular those who are geographically dispersed, such as military personnel.

英国武装部队中酒精滥用情况比普通人群更为严重。先前的研究表明，通过智能手机进行的干预措施在促进酒精使用自我监测方面有效，在减少酒精消费方面有作用，且覆盖面广。
这项单盲随机对照试验（RCT）旨在评估通过智能手机应用程序（Drinks:Ration）提供的为期28天的简短酒精干预措施，对有危险或有害饮酒水平且在临床环境中接受或已接受心理健康症状支持的退伍军人，在基线至3个月随访期间减少每周自我报告酒精消费量的效果。
在这项双臂单盲RCT中，将一个包含旨在增强参与者动机和个性化信息的交互功能的智能手机应用程序，与一个仅提供政府酒精消费指南的智能手机应用程序进行比较。该试验将在通过英国退伍军人心理健康慈善机构“战斗压力”寻求帮助的退伍军人人群中进行。招募、同意和数据收集将通过Drinks:Ration平台自动进行。主要结局是使用酒精消费时间线追溯法测量的基线（第0天）至3个月随访（第84天）期间自我报告的每周酒精消费量的变化。次要结局指标包括：（1）基线至3个月随访（第84天）酒精使用障碍识别测试分数的变化；（2）基线至3个月随访（第84天）世界卫生组织生活质量简表分数的变化，以评估调整生命年的质量。过程评估指标包括：（1）应用程序使用情况；（2）通过移动健康应用程序可用性问卷测量的可用性评级。主要和次要结局还将在6个月随访（第168天）时重新评估，以评估干预措施的长期益处，这将作为次要结局报告。
该研究将于2020年10月开始招募，预计需要12个月完成。研究结果将于2022年发表。
本研究评估一款智能手机应用程序，对于通过“战斗压力”寻求帮助的退伍军人人群，利用个性化信息和交互功能减少自我报告酒精消费量是否有效。这种创新方法若取得成功，可能提供一种实施低成本健康促进计划的手段，该计划有可能惠及大量人群，特别是那些地理上分散的人群，如军事人员。
