我们的目的是评估一个酒精减少应用程序的干预组件：少喝。过度饮酒者（AUDIT>=8）被招募来测试25析因试验中5个应用程序模块的增强版与最小版（功能减少）。模块有：自我监控和反馈，行动计划，身份改变，规范反馈，认知偏差再培训。结果指标为：每周饮酒量的变化（主要）;完整的AUDIT评分，应用程序使用情况，应用程序可用性（次要）。主要影响和双向交互作用采用意向治疗的方差分析进行评估。共纳入672名研究参与者。干预模块对每周饮酒量或AUDIT评分的变化没有显着的主要影响。强化规范反馈和认知偏差再培训对每周饮酒量的影响（F = 4.68，p = 0.03）以及强化自我监控和反馈与行动计划对AUDIT评分的影响（F = 5.82，p = 0.02）之间存在双向交互作用。与最小版本相比，增强型自我监控和反馈的使用频率更高，并且在帮助性、满意度和推荐他人方面的评分更高。总之，在对少喝酒智能手机应用程序的评估中，加强规范反馈和认知偏差再训练以及加强自我监测和反馈以及行动计划的组合在4周后改善了酒精相关的结果。
Our aim was to evaluate intervention components of an alcohol reduction app: Drink Less. Excessive drinkers (AUDIT>=8) were recruited to test enhanced versus minimal (reduced functionality) versions of five app modules in a 25 factorial trial. Modules were: Self-monitoring and Feedback, Action Planning, Identity Change, Normative Feedback, and Cognitive Bias Re-training. Outcome measures were: change in weekly alcohol consumption (primary); full AUDIT score, app usage, app usability (secondary). Main effects and two-way interactions were assessed by ANOVA using intention-to-treat. A total of 672 study participants were included. There were no significant main effects of the intervention modules on change in weekly alcohol consumption or AUDIT score. There were two-way interactions between enhanced Normative Feedback and Cognitive Bias Re-training on weekly alcohol consumption (F = 4.68, p = 0.03) and between enhanced Self-monitoring and Feedback and Action Planning on AUDIT score (F = 5.82, p = 0.02). Enhanced Self-monitoring and Feedback was used significantly more often and rated significantly more positively for helpfulness, satisfaction and recommendation to others than the minimal version. To conclude, in an evaluation of the Drink Less smartphone application, the combination of enhanced Normative Feedback and Cognitive Bias Retraining and enhanced Self-monitoring and Feedback and Action Planning yielded improvements in alcohol-related outcomes after 4-weeks.
