PROJECT SUMMARY Over 40% of children in Brazil live in poverty that is often severe and carries with it a significant risk for mental illness. Existing interventions can help alleviate mental health problems in children, yet the capacity to implement these interventions is limited across the globe, and particularly in low-resourced settings. Because they are highly scalable, social interventions such as cash transfer programs offer a promising approach that may limit a critical social driver of mental illness, adverse childhood experiences (ACEs), thereby reducing an important social burden arising from poverty – child mental illness. We propose a 24-month randomized clinical trial involving 300 households to examine causal effects of cash transfers on child neurodevelopment and mental health. Our study builds off of the largest cash transfer program in the world, Bolsa Familia, that has been in place in Brazil for over 2 decades. Consistent with the goals of RFA-MH-21-160, our study includes a mechanistic framework, testing whether cash transfers reduce new onset ACEs, protecting child brain and behavioral development by limiting inflammation and hypothalamic- pituitary-adrenal (HPA) activity (cortisol). With pre- and post-intervention assessments that include brain MRI scans, behavioral assays, and symptom measures, we will index the neurodevelopmental effects of cash transfers across multiple units of analysis. Although cash transfer programs are becoming increasingly common, their effects on child mental health remain poorly characterized particularly in low/middle income countries where poverty is widespread. Because our proposed study builds off of Bolsa Familia, a well-established program with a successful, national infrastructure for transferring cash, our findings could rapidly move toward implementation. Moreover, by providing mechanistic insights, our study will take a key step needed for refining Bolsa Familia and other cash transfer programs, facilitating studies aimed at targeting the specific populations that are most likely to benefit, optimizing the dose/amount of the transfers, and determining the ideal timing/duration for intervention.

项目概要 巴西超过 40% 的儿童生活在贫困之中，贫困状况往往十分严重，并伴随着严重的贫困 现有的干预措施可以帮助减轻儿童的心理健康问题， 然而，全球实施这些干预措施的能力有限，特别是在 因为它们具有高度可扩展性，因此可以采用现金等社会干预措施。 转移计划提供了一种有前途的方法，可以限制精神疾病的关键社会驱动因素， 不良童年经历（ACE），从而减轻因不良童年经历（ACE）而产生的重要社会负担 贫困——儿童精神疾病。我们建议进行一项为期 24 个月的随机临床试验，涉及 300 名儿童。 家庭检查现金转移对儿童神经发育和心理的因果影响 我们的研究建立在世界上最大的现金转移计划——家庭补助计划（Bolsa Familia）的基础上。 我们的政策已在巴西实施了 20 多年，与 RFA-MH-21-160 的目标一致。 研究包括一个机制框架，测试现金转移是否减少新出现的 ACE， 通过限制炎症和下丘脑来保护儿童大脑和行为发育 垂体肾上腺 (HPA) 活动（皮质醇）。 包括脑部 MRI 扫描、行为分析和症状测量，我们将索引 跨多个分析单位的现金转移对神经发育的影响 转学计划越来越普遍，但其对儿童心理健康的影响仍然存在 特征较差，特别是在贫困普遍存在的低/中等收入国家。 因为我们提出的研究建立在 Bolsa Familia 的基础上，这是一个完善的计划， 成功的国家现金转移基础设施，我们的研究结果可能会迅速转向 此外，通过提供机制见解，我们的研究将迈出关键一步。 完善 Bolsa Familia 和其他现金转移计划所需的资金，促进旨在 针对最有可能受益的特定人群，优化剂量/数量 转移，并确定干预的理想时机/持续时间。
