Purpose The purpose of this investigation was to measure the test-retest stability of single-word intelligibility in a group of 28 speakers with chronic apraxia of speech and aphasia. Method The Assessment of Intelligibility of Dysarthric Speech was administered twice to each participant, with samples separated by 1 week. Scoring of recorded samples was completed independently by three expert listeners using transcription and multiple-choice scoring formats. Results Percent intelligible words was very similar for the group over the two sampling times for both scoring formats (i.e., within 1.5%), with no statistically significant differences found between times. Statistically significant, very strong, positive correlations were found between sampling times for intelligibility scores. Transcription and multiple-choice scores were strongly, positively correlated, with multiple-choice scores being statistically higher. There was a statistically significant difference between mean transcription and multiple-choice scores for the group at Time 1 and Time 2. Individual performance was similar to group performance for the majority of participants. Conclusions These findings indicate that single-word intelligibility measures are stable over repeated sampling occasions. Stability was evident for transcription and multiple-choice scoring methods.

目的 本研究旨在测量 28 名慢性言语失用症和失语症患者的单字清晰度的重测稳定性。 方法 对每位参与者进行两次评估，两次测试之间间隔一周。三名专家听众分别使用转录和多项选择评分格式对录制的样本进行独立评分。 结果 对于两种评分格式，在两次采样时间内，组内的可理解单词百分比非常相似（即，在 1.5%以内），并且在时间之间未发现统计学上的显着差异。 可理解性得分之间的采样时间之间存在统计学上显着的，非常强的正相关关系。 转录和多项选择分数之间呈强正相关，多项选择分数在统计学上更高。 在时间 1 和时间 2 ，组的平均转录和多项选择分数之间存在统计学差异。对于大多数参与者，个体表现与组表现相似。 结论 这些发现表明，单字清晰度测量在重复采样时是稳定的。稳定性在转录和多项选择评分方法中都很明显。
