Digital health interventions (DHIs) have frequently been highlighted as one way to respond to increasing levels of mental health problems in children and young people. Whilst many are developed to address existing mental health problems, there is also potential for DHIs to address prevention and early intervention. However, there are currently limitations in the design and reporting of the development, evaluation and implementation of preventive DHIs that can limit their adoption into real-world practice. This scoping review aimed to examine existing evidence-based DHI interventions and review how well the research literature described factors that researchers need to include in their study designs and reports to support real-world implementation. A search was conducted for relevant publications published from 2013 onwards. Twenty-one different interventions were identified from 30 publications, which took a universal (n = 12), selective (n = 3) and indicative (n = 15) approach to preventing poor mental health. Most interventions targeted adolescents, with only two studies including children aged ≤10 years. There was limited reporting of user co-design involvement in intervention development. Barriers and facilitators to implementation varied across the delivery settings, and only a minority reported financial costs involved in delivering the intervention. This review found that while there are continued attempts to design and evaluate DHIs for children and young people, there are several points of concern. More research is needed with younger children and those from poorer and underserved backgrounds. Co-design processes with children and young people should be recognised and reported as a necessary component within DHI research as they are an important factor in the design and development of interventions, and underpin successful adoption and implementation. Reporting the type and level of human support provided as part of the intervention is also important in enabling the sustained use and implementation of DHIs.

数字健康干预措施 (DHI) 经常被强调为应对儿童和青少年日益严重的心理健康问题的一种方法。虽然许多 DHI 是为了解决现有的心理健康问题而开发的，但 DHI 也有可能解决预防和早期干预问题。然而，目前预防性 DHI 的开发、评估和实施的设计和报告存在局限性，这可能会限制其在现实世界实践中的采用。本次范围界定审查旨在审查现有的基于证据的 DHI 干预措施，并审查研究文献如何很好地描述研究人员需要纳入其研究设计和报告以支持现实世界实施的因素。检索了2013年以来出版的相关出版物。从 30 份出版物中确定了 21 种不同的干预措施，这些干预措施采用普遍 ( n = 12)、选择性 ( n = 3) 和指示性 ( n = 15) 的方法来预防心理健康状况不佳。大多数干预措施针对青少年，只有两项研究包括 ≤10 岁的儿童。关于用户协同设计参与干预开发的报道有限。实施的障碍和促进因素因实施环境而异，只有少数报告了实施干预措施所涉及的财务成本。本次审查发现，尽管人们不断尝试为儿童和青少年设计和评估 DHI，但仍存在几个令人担忧的问题。需要对年幼的儿童以及来自贫困和服务不足的背景的儿童进行更多研究。 与儿童和青少年的共同设计过程应被视为 DHI 研究的必要组成部分，因为它们是干预措施设计和开发的重要因素，并支持成功采用和实施。报告作为干预措施一部分提供的人力支持的类型和水平对于实现 DHI 的持续使用和实施也很重要。
