项目摘要

Project Abstract People with aphasia (PWA) and their families indicate that regaining the ability to converse with others is one of their greatest rehabilitation goals. Despite the critical importance of conversation in every facet of daily life, research-based language interventions aimed specifically at conversation do not exist. Critical to development of such intervention are relevant and reliable methods to measure change in language production at the conversation level. Thus, to meet this need, the broad, long-term the goals of this project are to determine which micro and macrolinguistic measures are reliable for use in measuring linguistic skills in conversation in PWA. Further, this research will provide knowledge required for appropriate clinical use of the measures (i.e., relationship of each measures in narrative and conversational discourse contexts) and for appropriate interpretation (i.e. understanding of functioning of healthy adults (HA) for three measures not expected to be at ceiling).The findings of this study will have public health impact by providing foundational knowledge needed for comprehensive assessment of aphasia that includes conversation-level discourse. Further, public health will be affected because the findings of this research will permit the much-needed development of relevant, effective treatment specifically directed to conversation, crucial to the health, well-being and recovery of independence in PWA. This research is situated directly within the scope of the NIDCD’s Strategic Plan for 2017-2021. The study will provide data meeting the need for research that extends the knowledge base in the understanding of normal function and dysfunction (aphasia) within the domain of a functional communication need (conversation), while providing foundational knowledge that can impact diagnosis, and treatment, and improve overall outcome for human communication, stated goals of the NIDCD. A group study design will be used to address: Specific Aim 1: Evaluate the test-retest stability of word- and utterance level discourse measures of micro and macrolinguistic skills and communicative success (CS) in PWA and HA during unstructured conversations with two unfamiliar Speech Language Pathologist partners experienced in working with PWA (SLP-Ps). Specific Aim 2: Evaluate presence and extent of significant between group differences for PWA and matched HA groups for three measures of informativeness, global cohesion and CS in conversation with an SLP-P. Specific Aim 3: Evaluate significance and extent of correlation of each measure in unstructured conversational discourse and structured narrative (story-telling via wordless picture book) in PWA. This research will be conducted in Dr. Lisa Edmonds’ Aphasia Research and Bilingualism Lab at Teachers College, Columbia University, an environment providing space, equipment, an extensive research library, materials, and opportunity for intellectual dialogue. The proposed training plan is designed to provide experiences and support to the PI needed to further her development as an independent researcher.

项目摘要失语症（PWA）患者及其家人表示，恢复与他人匡威的能力是治疗失语症的关键之一。最大的康复目标。尽管对话在日常生活的各个方面都至关重要，专门针对对话的基于研究的语言干预并不存在。对发展至关重要这些干预措施是相关的和可靠的方法来衡量语言生产的变化，对话水平。因此，为了满足这一需求，本项目的广泛、长期目标是确定微观和宏观语言学测量方法在PWA会话语言技能测量中是可靠的。此外，本研究将提供适当临床使用这些措施所需的知识（即，在叙事和会话语境中的每种措施的关系），并为适当的解释（即理解健康成人（HA）的三项指标的功能，这项研究的结果将通过提供所需的基础知识对公共卫生产生影响，失语症的全面评估，包括对话水平的话语。此外，公共卫生将影响，因为这项研究的结果将允许急需的相关，有效的发展，专门针对谈话的治疗，对健康，福祉和恢复独立至关重要在PWA。这项研究直接属于NIDCD 2017-2021年战略计划的范围。的研究将提供满足研究需要的数据，以扩大知识基础，功能性沟通需求（对话）领域内的正常功能和功能障碍（失语症），同时提供可以影响诊断和治疗并改善整体结果的基础知识人类交流，NIDCD的既定目标。将采用分组研究设计来解决：具体目标1：评估微观和言语层面话语测量的重测稳定性，在非结构化对话中，PWA和HA的宏语言技能和交际成功（CS）两个不熟悉的言语语言病理学家合作伙伴在工作与PWA（SLP-Ps）。具体目标2：评价PWA和匹配的组间差异的存在和程度 HA组的三个措施的信息，全球凝聚力和CS在交谈中与SLP-P。具体目标3：评估非结构化会话中每个测量的重要性和相关程度话语和结构化叙事（通过无字图画书讲故事）在PWA。这项研究将在丽莎埃德蒙兹博士的失语症研究和教师双语实验室进行学院，哥伦比亚大学，一个环境提供空间，设备，一个广泛的研究图书馆，材料和知识对话的机会。拟议的培训计划旨在提供经验和支持PI需要进一步发展作为一个独立的研究人员。
