Researchers examined whether a parent-implemented language intervention improved problem behaviors 1 year after intervention. Ninety-seven children with language delays (mean age at 12-month follow-up = 48.22 months) were randomized to receive Enhanced Milieu Teaching (EMT) language intervention or business as usual treatment. Twelve months after the intervention ended, children in the EMT intervention condition displayed lower rates of parent-reported externalizing, internalizing, and total problem behaviors. A mediation analysis revealed that the relation between EMT and problem behaviors was partially mediated by child rate of communication for both internalizing and total problem behaviors. A developmental framework is proposed to explain the impact of EMT on problem behaviors, and future lines of research are discussed.
研究人员考察了父母实施的语言干预是否能改善干预 1 年后的问题行为。97 名语言发育迟缓的儿童(12 个月随访时的平均年龄为 48.22 个月)被随机分为接受强化环境教学(EMT)语言干预或常规治疗。干预结束 12 个月后,EMT 干预组的儿童的父母报告的外化、内化和总问题行为发生率较低。中介分析表明,在内部问题行为和总问题行为方面,EMT 与问题行为之间的关系部分通过儿童沟通率来介导。提出了一个发展框架来解释 EMT 对问题行为的影响,并讨论了未来的研究方向。
