项目摘要
ABSTRACT
Child maltreatment is associated with health risk behaviors carrying high personal and societal costs,
such as substance use and sexual risk behavior.1–4 Placement of children into out-of-home care aims to
mitigate these negative effects.5 Findings about rates of health risk behavior among youth in out-of-home care
are mixed,6–16 although studies show that young adults formerly in care have heightened levels of health risk
behavior.17–20 These mixed findings may be due to the fact that most studies test effects of placement across
childhood on later health risk behaviors. However, placement during adolescence may be a turning point that
redirects trajectories of health risk behavior. Adolescence is a period of rapid change and a typical period for
initiation of these behaviors,21 and adolescents have more difficulties adjusting to placement than do younger
children.22 To test whether adolescent placement acts as a turning point, it is important to know whether
placement initiates long-term changes in trajectories, short-term (time-specific) changes, or both. To design
interventions, it is also necessary to understand the mechanisms underlying placement effects. However,
because placement may occur at various points across time, identifying its direct and mediated effects requires
modeling out-of-home placement, mediators, confounders, and outcomes as time-varying variables.
Importantly, out-of-home placement is a nonrandom event, and many pre-placement variables likely
predict both placement and subsequent health risk behavior. To deal with this threat to causal inference, recent
research has utilized propensity score methods.23–27 However, these methods cannot accommodate time-
varying variables, precluding tests of placement as a turning point or tests of its time-specific mediators.
Accordingly, the proposed study uses two modern methods for causal inference, inverse probability of
treatment weighting (IPTW) and g-estimation, to test direct and mediated effects of placement on health risk
behaviors across time. These methods can account for biases from observed confounders and accommodate
time-varying variables.28,29 Aim 1 tests whether adolescents with out-of-home placement since the prior wave
show short-term, time-specific increases in substance use and initiation of unprotected sex, compared to those
who remain in-home. Aim 2 tests whether adolescent placement predicts longer-term elevations in adult health
risk behavior. Aim 3 tests time-varying mediators of the effect of placement on adult health risk behavior.
These aims will be tested in a national sample of 738 maltreated youth (age 11-14 at baseline) studied across
four waves to adulthood. The training plan brings together a distinguished mentoring team to provide
multidisciplinary training in child welfare system research, modern quantitative methods for causal inference,
developmental psychopathology of health risk behaviors, implications for intervention and policy, and
professional development. This will provide the applicant with the foundation to launch a research career
studying the effects of placement and child welfare involvement on adolescents' developmental outcomes.
抽象的
虐待儿童与健康风险行为相关,带来高昂的个人和社会成本,
例如物质使用和危险性行为。1-4 将儿童安置在家庭外护理的目的是
减轻这些负面影响。5 关于户外护理中青少年健康风险行为比率的调查结果
好坏参半,6-16 尽管研究表明以前接受护理的年轻人有胃肠道健康风险
17-20 这些好坏参半的结果可能是由于大多数研究测试了不同阶段的安置效果。
然而,青春期的安置可能是一个转折点
改变健康风险行为的轨迹 青春期是一个快速变化的时期,也是一个典型的时期。
开始这些行为21,青少年比年轻人更难以适应安置
22 要测试青少年的安置是否是一个转折点,重要的是要知道是否
布局会引发轨迹的长期变化、短期(特定时间)变化或两者兼而有之。
干预措施中,还需要了解安置效应的潜在机制。
由于放置可能发生在不同时间点,因此识别其直接和中介效应需要
将户外安置、中介因素、混杂因素和结果建模为随时间变化的变量。
重要的是,户外安置是一个非随机事件,许多安置前的变量可能
为了应对因果推理的威胁,最近出现了预测放置和随后的健康风险行为。
研究利用了倾向评分方法。23-27 然而,这些方法不能适应时间-
变化的变量,排除作为转折点的放置测试或对其特定时间中介的测试。
因此,拟议的研究使用两种现代方法进行因果推理,即逆概率
治疗权重 (IPTW) 和 g 估计,以测试放置对健康风险的直接和中介影响
这些方法可以解释观察到的混杂因素带来的偏差并适应。
随时间变化的变量。28,29 目标 1 测试自上一波以来青少年是否处于户外安置状态
与那些人相比,显示出短期的、特定时间的物质使用和开始无保护性行为的增加
目标 2 测试青少年的安置是否可以预测成人健康状况的长期改善。
目标 3 测试随时间变化的中介因素对成人健康风险行为的影响。
这些目标将在 738 名受虐待青少年(基线年龄为 11-14 岁)的全国样本中进行测试。
培训计划汇集了杰出的指导团队,提供四波成年培训。
儿童福利系统研究的多学科培训、因果推理的现代定量方法、
健康风险行为的发展精神病理学、对干预和政策的影响,以及
这将为申请人的研究生涯奠定基础。
研究安置和儿童福利参与对青少年发展结果的影响。
