背景：关于智能手机应用程序减少不健康饮酒的功效的证据有限。我们测试了针对不健康饮酒提供基于智能手机的简短干预措施的有效性。方法：我们对 977 名酒精使用障碍识别测试 >= 8 且每周饮酒 15 杯或以上的个体进行了两项平行组随机对照试验，并在 6 个月内进行了随访。参与者被随机分配接受（或不接受）智能手机应用程序的访问，其中包括个性化反馈、风险评估和自我监控。主要结果是每周平均饮酒次数。进行了意向治疗分析（ITT）和按方案分析（PP）。结果：参与者的平均年龄为 34.2 岁（9.8 岁），其中 46% 为女性。基线平均每周饮酒次数为 28.9（16.7）。结果因分析类型而异： ITT：所有 977 名参与者均纳入分析。随访率为 70.7% (n = 691)。没有显着的干预效果：每周饮酒次数的发病率比（IRR）（95%CI）为0.93（0.84；1.03）。 PP：分析包含 702 名参与者。随访率为 78.1% (n = 548)。干预效果显着：每周饮酒次数的 IRR 为 0.88（0.78；0.99）。结论：提供基于智能手机的简短干预对 6 个月时的饮酒没有影响，并且似乎不是减少饮酒的有效干预措施。下载该应用程序的人似乎从中受益，但下载量有限，类似应用程序的进一步开发应侧重于增加使用量。
Background: There is limited evidence of the efficacy of smartphone applications to reduce unhealthy alcohol use. We tested the efficacy of providing access to a smartphone-based brief intervention for unhealthy alcohol use.Methods: We conducted a two parallel-group randomized controlled trial with follow-up at 6 months, among 977 individuals with an Alcohol Use Disorder Identification Test >= 8 and drinking 15 or more drinks/week. Participants were randomized to receive (or not) access to a smartphone application consisting of personalized feedback, risk assessment and self-monitoring. The primary outcome was the mean number of drinks/week. An intention to treat analysis (ITT) and a per protocol analysis (PP) were conducted.Results: Mean age of participants was 34.2(9.8), 46% were female. The baseline mean number of drinks per week was 28.9(16.7). Results differed by type of analysis: ITT: all 977 participants were included in the analysis. Follow-up rate was 70.7% (n = 691). There was no significant intervention effect: the Incidence Rate Ratio (IRR) (95%CI) for number of drinks per week was 0.93(0.84; 1.03). PP: 702 participants were included in the analysis. Follow-up rate was 78.1% (n = 548). There was a significant intervention effect: the IRR for number of drinks per week was 0.88(0.78; 0.99).Conclusions: Providing access to a smartphone-based brief intervention had no impact on drinking at 6 months and does not appear to be an effective intervention in reducing drinking. Those who downloaded the app appear to benefit from it, nevertheless downloads were limited and further development of similar apps should focus on increasing use.
