OBJECTIVE Behavioral parent training (BPT) is the standard of care for early onset behavior disorders (BDs), however, not all families benefit. Emotion regulation (ER) is one potential mechanism underlying BPT outcomes, yet there are challenges in capturing intra- and interpersonal aspects of emotion regulation within parent-child interactions that are central to BPT. This study examined how vocally encoded emotional arousal unfolds during parent-child interactions and how parents and children influence each other's arousal (Aim 1), the links between these emotion dynamics, child behavior, and parenting at baseline (Aim 2), and BPT outcome (Aim 3). METHOD Families of children with BDs (N = 45) completed two interaction tasks and measures of parenting and child behavior. Parent-child dynamics of vocal fundamental frequency (f₀) were modeled using actor-partner interdependence models (APIMs) and coupled linear oscillators (CLOs). RESULTS When considering relative levels of f₀ from one talk turn to the next (APIMs), parents and children showed intrapersonal regulation and synchronizing reactivity to each other's f₀. When considering the shape of oscillations (CLOs), parents and children showed intrapersonal regulation but no reactivity. Intrapersonal regulation of f₀ during the interaction was slowed for parents with more maladaptive parenting and children with more behavior problems at baseline. CONCLUSIONS This preliminary characterization of f0 in families presenting for BPT provides insights into the emotion dynamics potentially underlying parenting behavior and child behavior.

接受行为父母培训的家庭中的亲子情绪动态：与儿童行为、养育和治疗结果是否存在联系？


目标 家长行为培训 (BPT) 是早发行为障碍 (BD) 的护理标准，但并非所有家庭都能受益。情绪调节（ER）是 BPT 结果的一种潜在机制，但在亲子互动中捕捉情绪调节的内部和人际方面存在挑战，而这对于 BPT 至关重要。本研究探讨了亲子互动期间声音编码的情绪唤醒如何展开，以及父母和孩子如何影响彼此的唤醒（目标 1），这些情绪动态、儿童行为和基线养育之间的联系（目标 2）以及 BPT 结果（目标 3）。方法 BD 儿童家庭 (N = 45) 完成两项互动任务以及养育和儿童行为的测量。使用演员-合作伙伴相互依赖模型（APIM）和耦合线性振荡器（CLO）对声音基频（f₀）的亲子动态进行建模。结果当考虑从一次谈话到下一次谈话的 f₀ 相对水平 (APIM) 时，父母和孩子表现出内心调节和对彼此 f₀ 的同步反应。当考虑振荡形状（CLO）时，父母和孩子表现出内心调节，但没有反应。对于那些不适应养育方式的父母和基线时有更多行为问题的孩子，在互动过程中对 f₀ 的个人调节会减慢。结论 参加 BPT 的家庭中 f0 的初步特征提供了对潜在的养育行为和儿童行为背后的情绪动态的见解。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
