目的：口吃频率的变化使得治疗结果研究的结果难以解释。许多影响变异性的因素已被调查，但由扬声器所经历的变异性的典型范围仍然未知。本研究探讨了一天到一天的变化，在三个自发发言的情况下，两个阅读task.Methods：在任务中的时刻口吃的频率进行了比较内和扬声器和天之间的口吃频率的变化程度，并探讨是否有任何一致的模式，在六个成人扬声器的语音中包含口吃和不流利的音节的百分比。口吃严重程度工具-第四版（SSI-4）和成人口吃的演讲者的经验（OASES-A）的总体评估也进行了测试的日常变化。频率，严重程度和生活impacts.Results之间的相关性：本研究的主要结果是大范围的口吃频率不同，每天为同一个人。这种变异性与口吃严重程度的任何测量都不相关，但与OASES-A测量的生活影响相关。在参与者内或参与者之间，没有检测到每天的变异性的全球模式。然而，有显着更多的非口吃的不流利出现在自发说任务比在阅读任务。日常生活中的变化的障碍（OASES-A）的影响是小于每天的变化，在可观察到的口吃行为（音节口吃和SSI-4的百分比）。结论：口吃的频率变化显着的情况下，每天的情况，观察到的变化超过了治疗结果的研究，从治疗前到治疗后经常报告的变化程度。在未来的临床和科学工作中，必须考虑到这种变异性。(C)2016 Elsevier Inc.

Purpose: Variability in frequency of stuttering has made the results of treatment outcome studies difficult to interpret. Many factors that affect variability have been investigated; yet the typical range of variability experienced by speakers remains unknown. This study examined the day-to-day variability in the percentage of syllables containing stuttered and nonstuttered disfluencies in the speech of six adult speakers in three spontaneous speaking situations and two reading tasks.Methods: The frequency of moments stuttering during the tasks were compared within and between speakers and days to document the degree of variability in stuttering frequency and explore whether there were any consistent patterns. The Stuttering Severity Instrument-Fourth Edition (SSI-4) and Overall Assessment of the Speaker's Experience of Stuttering for Adults (OASES-A) were also tested for day-to-day variability. Correlations between frequency, severity, and life impact were made.Results: The primary result of this study was the large range over which frequency of stuttering varied from day to day for the same individual. This variability did not correlate with any measures of stuttering severity but did correlate with life impact as measured by the OASES-A. No global pattern was detected in variability from day to day within or between participants. However, there were significantly more nonstuttered disfluencies present during the spontaneous speaking tasks than during the reading tasks. The day-to-day variability in the life impact of the disorder (OASES-A) was less than the day-to-day variability in observable stuttering behavior (percentage of syllables stuttered and SSI-4).Conclusion: Frequency of stuttering varies significantly from situation to situation and day to day, with observed variability exceeding the degree of change often reported in treatment outcomes studies from before to after treatment. This variability must be accounted for in future clinical and scientific work. (C) 2016 Elsevier Inc. All rights reserved.
