This study used data on 2,453 children aged 4-17 from the National Survey of Child and Adolescent Well-Being and 5 analytic methods that adjust for selection factors to estimate the impact of out-of-home placement on children's cognitive skills and behavior problems. Methods included ordinary least squares (OLS) regressions and residualized change, simple change, difference-in-difference, and fixed effects models. Models were estimated using the full sample and a matched sample generated by propensity scoring. Although results from the unmatched OLS and residualized change models suggested that out-of-home placement is associated with increased child behavior problems, estimates from models that more rigorously adjust for selection bias indicated that placement has little effect on children's cognitive skills or behavior problems.
本研究使用了来自全国儿童和青少年健康调查的 2453 名 4-17 岁儿童的数据，以及 5 种分析方法，这些方法调整了选择因素，以估计家庭外安置对儿童认知技能和行为问题的影响。方法包括普通最小二乘法（OLS）回归和残差变化、简单变化、差异差异和固定效应模型。使用全样本和通过倾向评分生成的匹配样本估计模型。尽管来自不匹配的 OLS 和残差变化模型的结果表明家庭外安置与儿童行为问题增加有关，但更严格地调整选择偏差的模型的估计表明，安置对儿童的认知技能或行为问题几乎没有影响。
