The aim of this study was to assess the available evidence on potential moderators of psychological and psychoeducational interventions for the prevention of anxiety. A systematic review using PubMed, PsycINFO, Web of Science, Embase, OpenGrey, and CENTRAL was performed up to October 2019. Two independent researchers assessed the fulfillment of eligibility criteria, extracted the data and performed a quality assessment of the included studies. Outcomes were moderators of the reduction of anxious symptoms or the incidence of anxiety disorders. Fourteen studies reporting results on moderator analyses performed in 13 randomized controlled trials were included. Twenty-seven potential moderators were organized into six categories: sociodemographic, clinical characteristics, cognitive variables, life events, interpersonal functioning and intervention characteristics. The most frequently examined variables were gender, age and baseline anxiety. We found insufficient evidence for all moderator categories studied. In children and adolescents, we found some studies with significant results for the low family support variable and higher levels of anxiety symptoms at baseline, which were both associated with higher effectiveness. Limited conclusions can be drawn about for whom and under what conditions interventions work in the prevention of anxiety. A strong need to improve the methodological quality and the number of moderator studies was identified.

这项研究的目的是评估有关预防焦虑的心理和心理教育干预措施的潜在主持人的现有证据。截止到2019年10月，使用PubMed，PsycINFO，Web of Science，Embase，OpenGrey和CENTRAL进行了系统评价。两名独立研究人员评估了合格标准的实现情况，提取了数据并对所纳入研究进行了质量评估。结果是减轻焦虑症状或焦虑症发生率的调节剂。包括14个研究，这些研究报告了13项随机对照试验中主持人分析的结果。二十七位潜在的主持人分为六类：社会人口统计学，临床特征，认知变量，生活事件，人际交往和干预特征。最经常检查的变量是性别，年龄和基线焦虑。对于所有研究的主持人类别，我们发现没有足够的证据。在儿童和青少年中，我们发现一些研究对低家庭支持变量和基线时较高的焦虑症状水平均具有显着结果，两者均与较高的有效性相关。关于干预在什么情况下以及在什么情况下可以预防焦虑，只能得出有限的结论。确定了提高方法学质量的强烈需求，并确定了主持人研究的数量。我们发现一些关于低家庭支持变量和基线时较高焦虑症状水平的有意义的研究，两者均与较高的有效性相关。关于干预在什么情况下以及在什么情况下可以预防焦虑，只能得出有限的结论。确定了提高方法学质量的强烈需求，并确定了主持人研究的数量。我们发现一些关于低家庭支持变量和基线时较高焦虑症状水平的有意义的研究，两者均与较高的有效性相关。关于干预在什么情况下以及在什么情况下可以预防焦虑，只能得出有限的结论。确定了提高方法学质量的强烈需求，并确定了主持人研究的数量。
