There are over 40 million displaced children and youth worldwide and there is a need promote their mental wellbeing. This study aimed to synthesize evidence regarding promotion interventions to increase wellbeing, resilience, and quality of life (primary outcomes), and prevention interventions to reduce internalizing and externalizing symptoms (secondary outcomes) in this population. The review protocol was registered with PROSPERO (CRD42022329978). Medline, PsycINFO, and Web of Science were searched. Inclusion criteria were: ≥ 10 participants, sample ≤ 18 years of age, no parental participation, explicated forced migrant populations, implementation in non-clinical context, and validated measures. Fifteen studies (N interventions = 18, N participants = 5741) were eligible. Two studies included outcomes related to wellbeing and quality of life. The remaining studies reported depression, PTSD, anxiety, internalizing and externalizing behaviours, and behavioural and emotional problems. There was only sufficient data to perform random-effects meta-analysis of depression scores. No significant effects were observed in comparison to control condition in randomized trials (n = 4994, k = 5) but a small significant positive trend was observed in within-group analyses (n = 537, k = 12). Cochrane’s risk of bias tools and the GRADE certainty of evidence tool were applied. No studies achieved low risk of bias and certainty of evidence was very low. In sum, there remains a dearth of rigorous intervention studies investigating the effects of promotive and preventative psychological interventions on the wellbeing, resilience, and quality of life of forcibly displaced minors. However, the few eligible studies in this review indicate promise.

全球有超过 4000 万儿童和青少年流离失所，需要促进他们的心理健康。本研究旨在综合有关促进干预措施的证据，以提高该人群的福祉、复原力和生活质量（主要结果），以及预防干预措施以减少该人群的内化和外化症状（次要结果）。该审查方案已在 PROSPERO 注册（CRD42022329978）。检索了 Medline、PsycINFO 和 Web of Science。纳入标准为：≥10名参与者，样本≤18岁，无父母参与，明确的强迫流动人口，在非临床背景下实施，以及经过验证的措施。 15 项研究（N项干预 = 18，N名参与者 = 5741）符合资格。两项研究包括与福祉和生活质量相关的结果。其余的研究报告了抑郁、创伤后应激障碍、焦虑、内化和外化行为以及行为和情绪问题。只有足够的数据来对抑郁评分进行随机效应荟萃分析。与随机试验中的对照条件相比，未观察到显着效果（n  = 4994，k  = 5），但在组内分析中观察到小的显着正趋势（n  = 537，k  = 12）。应用 Cochrane 偏倚风险工具和 GRADE 证据确定性工具。没有研究达到低偏倚风险，并且证据的确定性非常低。总之，仍然缺乏严格的干预研究来调查促进性和预防性心理干预对被迫流离失所的未成年人的福祉、复原力和生活质量的影响。然而，本次综述中的少数几项符合条件的研究表明了希望。
