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.

项目摘要失语症患者 (PWA) 及其家人表示，重新获得与他人交谈的能力是其中之一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对于发展至关重要。这种干预措施的核心是衡量语言产生变化的相关且可靠的方法。因此，为了满足这一需求，该项目的广泛、长期目标是确定哪些。微观和宏观语言测量对于测量 PWA 对话中的语言技能是可靠的。此外，这项研究将提供适当临床使用这些措施所需的知识（即，叙述和对话语境中每个措施的关系）以及适当的解释（即了解健康成年人 (HA) 的功能，以了解预计不会达到的三项措施这项研究的结果将通过提供以下方面所需的基础知识来产生公共卫生影响：此外，还将对失语症进行全面评估，包括对话层面的话语。受到影响，因为这项研究的结果将有助于开发急需的相关的、有效的专门针对对话的治疗，对健康、福祉和恢复独立至关重要这项研究直接属于 NIDCD 2017-2021 年战略计划的范围。研究将提供满足研究需求的数据，扩展理解的知识基础功能性沟通需求（对话）范围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总体结果的基础知识对于人类沟通，NIDCD 的既定目标将用于解决：具体目标 1：评估微观和言语水平话语测量的重测稳定性。在与人进行非结构化对话期间，PWA 和 HA 中的宏观语言技能和沟通成功 (CS) 两位陌生的言语病理学家伙伴在 PWA (SLP-P) 方面拥有丰富的工作经验。具体目标 2：评估 PWA 和匹配组之间显着差异的存在和程度 HA 小组与 SLP-P 进行对话，以衡量信息量、全球凝聚力和 CS 三个指标。具体目标 3：评估非结构化会话中每个度量的重要性和相关程度 PWA 中的话语和结构化叙事（通过无字图画书讲故事）。这项研究将在 Lisa Edmonds 博士的失语症研究和双语教师实验室进行哥伦比亚大学学院，提供空间、设备、广泛的研究图书馆的环境，拟议的培训计划旨在提供知识对话的材料和机会。 PI 需要进一步发展她作为独立研究员的经验和支持。
