Guidance is scarce on whether and how to involve parents in treatment for anxiety and depressive disorders in children and young people. We did a scoping review of randomised controlled trials of psychological interventions for anxiety and depressive disorders in children and young people, in which parents were involved in treatment, to identify how parents and carers have been involved in such treatments, how this relates to both child and broader outcomes, and where research should focus. We identified 73 trials: 62 focused on anxiety and 11 on depressive disorders. How parents were involved in treatments varied greatly, with at least 13 different combinations of ways of involving parents in the anxiety trials and seven different combinations in the depression trials. Including parents in treatment did not impair children's and young people's outcomes, but the wide variability in how they were involved prevents clarity about why some trials favoured parent involvement and others did not. Studies must consider the long-term and wider benefits beyond children's and young people's mental health, such as enhanced engagement, family wellbeing, and economic gains.

关于是否以及如何让父母参与治疗儿童和年轻人的焦虑症和抑郁症的指南很少。我们对父母参与治疗的儿童和青少年焦虑和抑郁症的心理干预随机对照试验进行了范围界定审查，以确定父母和照顾者如何参与此类治疗，这与儿童和青少年的关系如何和更广泛的结果，以及研究的重点。我们确定了 73 项试验：62 项针对焦虑症，11 项针对抑郁症。父母参与治疗的方式差异很大，至少有 13 种不同的让父母参与焦虑试验的方式组合和 7 种不同的抑郁症试验组合。让父母参与治疗不会损害儿童的 s 和年轻人的结果，但他们参与方式的广泛可变性使人们无法弄清楚为什么有些试验有利于父母参与，而另一些则没有。研究必须考虑儿童和年轻人心理健康之外的长期和更广泛的好处，例如提高参与度、家庭福祉和经济收益。
