While the relationship between adverse childhood experiences (ACEs) and mental health problems (depression, suicidal thoughts, PTSD, and functional impairments) among youth is well studied, there is less known about the mediating role played by resilience for youth receiving child welfare services. This study explored the mediating effects of resilience in relationship to ACEs and mental health outcomes for youth receiving child welfare services. Participants and setting: The study included 251 participants (14–19 years of age, 58% female) receiving child welfare services from the government of Nova Scotia, Canada. A cross-sectional design was used with seven measures administered to youth through phone interviews. Risk exposure was measured using the ACEs scale while resilience was assessed with the CYRM-17. Mental health outcomes included depression symptoms (BDI-II), suicidal thoughts (SBQ-R), post traumatic stress reactions (PTSRS), and functional impairment (IATSS). Structure equation modelling (SEM) and general linear model (GLM) were used to analyze the data. Resilience directly affects mental health outcomes (β = − 0.409, p < .001) and indirectly mediates the effect of ACEs on outcomes (β = 0.236, P < .001). Resilience showed different patterns in terms of sex and education. The youth who identified themselves as non-binary and were not enrolled in an educational program had lower levels of resilience. Resilience decreases the risk of mental health problems among youth receiving child welfare services. The impact of resources to build relational, caregiver, and social-contextual resilience may be influenced by a youth’s sexual identity and engagement in education.

虽然青少年不良童年经历 (ACE) 与心理健康问题（抑郁、自杀念头、创伤后应激障碍和功能障碍）之间的关系已得到充分研究，但人们对接受儿童福利服务的青少年的心理复原力所起的中介作用知之甚少。本研究探讨了复原力与接受儿童福利服务的青少年的 ACE 和心理健康结果之间的中介效应。参与者和环境：该研究包括 251 名参与者（14-19 岁，58% 女性），他们接受加拿大新斯科舍省政府的儿童福利服务。采用横断面设计，通过电话访谈对青少年采取七项措施。使用 ACE 量表测量风险暴露，并使用 CYRM-17 评估弹性。心理健康结果包括抑郁症状（BDI-II）、自杀念头（SBQ-R）、创伤后应激反应（PTSRS）和功能障碍（IATSS）。使用结构方程模型（SEM）和一般线性模型（GLM）来分析数据。复原力直接影响心理健康结果（ β = − 0.409， p < .001）并间接介导 ACE 对结果的影响（ β = 0.236， P < .001）。复原力在性别和教育方面表现出不同的模式。那些认为自己是非二元性别并且没有参加教育项目的年轻人的复原力水平较低。复原力降低了接受儿童福利服务的青少年出现心理健康问题的风险。建立关系、照顾者和社会背景复原力的资源的影响可能会受到青少年的性别认同和教育参与度的影响。
