Pregnant and parenting adolescents are more likely than adults to live with economic and social vulnerability, contributing to a higher risk of poorer maternal and newborn health outcomes. These same factors contribute to higher rates of postpartum child protection investigations among adolescents. This study describes an innovative approach to contextualize evidence on factors contributing to perinatal child protection involvement in the perspectives of pregnant and parenting adolescents. Using Weight of Evidence, an evidence-based participatory procedure, we conducted a conventional literature review and used fuzzy cognitive maps to contextualize evidence in the experiences of young mothers exposed to child protection investigations. Published evidence was contextualized through semi-structured mapping interviews with ten pregnant and parenting youth and subsequently shared with three child protection workers specialized in pre- and post-natal risk assessment. We developed and consolidated explanatory accounts describing how factors contribute to child protection involvement in the perinatal period among adolescent parents. We collaboratively designed and prioritized interventions strategies together with six adolescent parents. Young women highlighted mental health consequences of child protection involvement, including a reluctance to disclose their own health and social needs, challenges to their identity and self-confidence as parents, and social isolation. Women prioritized reducing the stigma they experience in accessing services, strengthening supportive relationships and greater understanding of their rights in child protection investigations as actionable intervention areas. Inputs of young women and service providers precipitated a reconceptualization of risk and identified how to support greater agency and self-determination among young parents experiencing child protection investigations.

怀孕和育儿的青少年比成年人更有可能生活在经济和社会脆弱的环境中，导致孕产妇和新生儿健康状况较差的风险更高。这些相同的因素导致青少年产后儿童保护调查的比例更高。本研究描述了一种创新方法，以从怀孕和育儿青少年的角度将有助于围产期儿童保护参与的因素的证据背景化。使用证据权重（一种基于证据的参与式程序），我们进行了传统的文献综述，并使用模糊认知地图将暴露于儿童保护调查的年轻母亲的经验中的证据置于情境中。通过对 10 名怀孕和育儿青少年的半结构化绘图访谈，将已发布的证据置于情境中，随后与 3 名专门从事产前和产后风险评估的儿童保护工作者分享。我们开发并整合了解释性说明，描述了青少年父母在围产期参与儿童保护的因素。我们与六位青少年父母合作设计并优先考虑干预策略。年轻女性强调了参与儿童保护的心理健康后果，包括不愿透露自己的健康和社会需求、对自己作为父母的身份和自信心的挑战以及社会孤立。妇女优先减少她们在获得服务方面的耻辱感，在儿童保护调查中加强支持性关系并更好地了解他们的权利，将其作为可操作的干预领域。年轻女性和服务提供者的投入促成了对风险的重新概念化，并确定了如何在经历儿童保护调查的年轻父母中支持更大的代理权和自决权。
