项目摘要

DESCRIPTION (provided by applicant): We have pioneered the development of a prelinguistic and linguistic milieu intervention (PLMT) designed to establish intentional communication and enhance the development of early communication and language development in toddlers and young children with language delays and disorders. PLMT involves direct intervention with toddlers as well as parent training designed to establish and support a highly responsive style of parent-child interaction. Our preliminary research using randomized experimental design s has involved a very small "dose" of direct intervention with the child, averaging approximately one hour per week for six months. The effects we have observed have been encouraging, but moderate, especially when measured directly after the 6-month intervention period. The proposed research is a test of the hypothesis that more intensive application of PLMT will have dramatically more positive outcomes, We propose an experimental investigation of the effects of PLMT delivered at two different levels of intensity to 80 young children with general communication delays randomly assigned to either a "high" or "low" intensity group. Children in the low- intensity group will receive one hour of direct intervention per week for 9 months while children assigned to the high-intensity group will receive 5 hours a week of direct intervention for 9 months. All subjects in both groups will be followed for an additional 6 months. Specific aims of the study are to compare the effects of high and low doses of PLMT on children's nonverbal and verbal communication skills. We will also test hypothesized interactions between the interventions and several child pretreatment characteristics and test predicted mediators for the predicted treatment effects. Analyses will include t-tests, 2x2 ANOVA, and multi-level analysis (HLM). Multiple regression or ANCOVA will be used if statistical control of pre-treatment differences are necessary. Five years of funding is requested.

描述（由申请人提供）：我们开发了旨在建立有意沟通并增强具有语言延迟和疾病的幼儿和幼儿的早期交流和语言发展的前后语言和语言干预（PLMT）的发展。 PLMT涉及与幼儿的直接干预以及旨在建立和支持高度响应的亲子互动风格的父母培训。我们使用随机实验设计S进行的初步研究涉及与孩子直接干预的非常小的“剂量”，平均每周大约一小时一个小时，持续六个月。我们观察到的影响令人鼓舞，但中度是中等的，尤其是在6个月干预期之后直接进行测量时。拟议的研究是对PLMT的更密集应用将具有更大的积极结果的假设的检验，我们提出了一个实验研究，对PLMT在两个不同水平的强度向80个具有随机分配给“高”或“低强度”组的一般沟通延迟的强度下的PLMT的影响进行了研究。低强度组的儿童每周将接受9个月的直接干预，而分配给高强度组的儿童将每周进行5个小时的直接干预9个月。两组中的所有受试者都将再遵循6个月。该研究的具体目的是比较高剂量和低剂量的PLMT对儿童非语言和口头交流技能的影响。我们还将测试干预措施与几个儿童预处理特征和测试预测治疗效果的介体之间的假设相互作用。分析将包括t检验，2x2 ANOVA和多级分析（HLM）。如果需要对预处理差异的统计控制，将使用多元回归或ANCOVA。要求提供五年的资金。
