失语症患者表示，改善会话话语是主要的康复目标。话语通常用独白来评估，比如图片描述任务，但研究表明，独白中的语言与日常对话中的语言不同。因此，我们研究了非结构化对话和野餐场景图片中的语言关系，因为它是最常用的失语电池（西方失语电池-修订）的一部分，因此经常用于告知治疗。其次，由于先前的研究表明，严重失语症患者可能不会在独白级话语类型之间表现出语言产生的差异，因此我们评估了严重失语症与对话和野餐场景任务之间得分差异的关系。方法34例轻度至重度失语症患者描述野餐场景并提供谈话样本。我们在对话/独白中使用七种已建立的心理测量方法来测量语言产生和交际成功。我们通过相关性来回答研究问题。结果在两种情况下，相关系数均为中等且较弱。失语症的严重程度与整体连贯性呈显著负相关。当与失语症严重程度相关时，所有其他的关系都是中等的，其余的测量结果较弱（也是负相关）。结论：研究结果与其他研究一致，表明语言在不同类型的话语中存在差异。我们的结论是，为了准确而有意义的评估，话语抽样需要包括个体希望在治疗中处理的特定话语类型，因为话语样本及其发现是不可互换的。
PURPOSE People with aphasia express that improved conversational discourse is a primary rehabilitation goal. Discourse is usually assessed using monologue, such as a picture description task, but research shows that language in monologue varies from language in everyday conversation. Consequently, we investigated the relationship of language in unstructured conversation and in the picnic scene picture because it is a part of the most often used aphasia battery (Western Aphasia Battery-Revised) and thus is frequently used to inform therapy. Second, because previous research suggests people with severe aphasia may not demonstrate language production variability between types of monologue-level discourse, we evaluated the relationship of severity and the difference in scores between conversation and the picnic scene task. METHOD Thirty-four people with mild-to-severe aphasia described the picnic scene and provided a conversation sample. We measured language production and communicative success using seven measures with established psychometrics in conversation/monologue. We conducted correlations to answer the research questions. RESULTS Correlations were moderate and weaker for the measures in the two conditions. A strong negative relationship was demonstrated between aphasia severity and global coherence. All other relationships were moderate and weaker for the remaining measures when correlated with aphasia severity (also negative). CONCLUSIONS Results are consistent with other studies indicating that language varies in different types of discourse. We conclude that for accurate, meaningful assessment, discourse sampling needs to include the specific type of discourse the individual wishes to address in therapy, because discourse samples and their findings are not interchangeable.
