在一项随机预防试验中，238名最近分居的母亲和他们的年幼儿子被分配到父母管理培训（PMT）或对照组。家庭在基线和每6个月的时间间隔到30个月进行了密集评估。为了了解PMT的影响，我们首先评估了随着时间的推移家庭变量之间的效应大小。第二，因为观察到的养育是PMT的目标，我们假设一个连续的模式，结构化的变化内和之间的个人。使用结构与不匹配的数据来源，我们进行了一组潜在的增长中介分析，以测试假设的机制解释的变化。效应量表明，父母在12个月内首先改变，其次是男孩行为的变化，最后是母亲抑郁症在30个月内的变化。独特的后续研究结果表明，减少母亲抑郁症的干预效果介导的男孩外化减少外化干预效果介导的男孩抑郁症的减少。正如预期的那样，有效养育的增加预示着儿童行为问题的减少。PMT对内化的影响是直接和间接的，部分由父母教养方式介导。从系统的角度对PMT放大器的结果进行了讨论。
In a randomized prevention trial, 238 recently separated mothers and their young sons were assigned to either Parent Management Training (PMT) or a comparison group. Families were intensively assessed at baseline and at each 6-month interval through 30 months. To understand the effects of PMT, we first evaluated effect sizes among family variables over time. Second, because observed parenting was the target of PMT, we hypothesized a sequential pattern of structured changes within and between individuals. Using constructs with mismatched sources of data, we conducted a set of latent growth mediational analyses to test hypothesized mechanisms explaining change. Effect sizes indicated that parenting changed first within 12 months, followed by changes in boy behaviors and finally changes in maternal depression within 30 months. Unique follow-up findings indicated that intervention effects on reductions in maternal depression were mediated by reductions in boy externalizing; intervention effects on externalizing were mediated by reductions in boy depression. As expected, increases in effective parenting predicted reductions in child behavior problems. PMT effects on internalizing were direct and indirect, partially mediated by parenting practices. Results are discussed from a system's perspective on PMT amplifiers.
