Digital interventions have the potential to reduce alcohol consumption, although evidence on the effectiveness of apps is lacking. is a popular, evidence-informed app with good usability, putting it in a strong position to be improved upon prior to conducting a confirmatory evaluation. This paper describes the process of refining to improve its usability and likely effectiveness. The refinement consisted of three phases and involved qualitative and quantitative (mixed) methods: i) identifying changes to app content, based on findings from an initial evaluation of , an updated review of digital alcohol interventions and a content analysis of user feedback; ii) designing new app modules with public input and a consultation with app developers and researchers; and iii) improving the app's usability through user testing. As a result of the updated review of digital alcohol interventions and user feedback analysis in Phase 1, three new modules: 'Behaviour Substitution', 'Information about Antecedents' and 'Insights', were added to the app. One existing module - 'Identity Change' - was removed based on the initial evaluation of . Phases 2 and 3 resulted in changes to existing features, such as improving the navigational structure and onboarding process, and clarifying how to edit drinks and goals. A mixed methods approach was used to refine the content and design of , providing insights into how to improve its usability and likely effectiveness. is now ready for a confirmatory evaluation.
数字干预措施有可能减少饮酒量，尽管缺乏关于应用程序有效性的证据。 是一款流行的、基于证据的应用程序，具有良好的可用性，使其在进行确认性评估之前有很大的改进空间。本文描述了改进 的过程，以提高其可用性和可能的效果。改进包括三个阶段，涉及定性和定量（混合）方法：i）根据 初步评估、对数字酒精干预措施的最新审查以及对用户反馈的内容分析，确定对应用程序内容的更改；ii）在公众的参与下设计新的应用程序模块，并与应用程序开发人员和研究人员进行协商；iii）通过用户测试提高应用程序的可用性。由于在第 1 阶段对数字酒精干预措施和用户反馈分析的更新审查，该应用程序添加了三个新模块：“行为替代”、“关于前因的信息”和“见解”。根据 初步评估，一个现有模块 -“身份变更”被删除。第 2 阶段和第 3 阶段导致了现有功能的更改，例如改进导航结构和入门流程，并澄清了如何编辑饮料和目标。混合方法用于改进 的内容和设计，深入了解如何提高其可用性和可能的效果。 现在已准备好进行确认性评估。
