Much research and clinical work in speech-language pathology depends on the validity and reliability of data gathered through the direct observation of human behavior. This paper reviews several definitions of reliability, concluding that behavior observation data are reliable if they, and the experimental conclusions drawn from them, are not affected by differences among observers or by other variations in the recording context. The theoretical bases of several methods commonly used to estimate reliability for observational data are reviewed, with examples of the use of these methods drawn from a recent volume of the Journal of Speech and Hearing Research (35, 1992). Although most recent research publications in speech-language pathology have addressed the issue of reliability for their observational data to some extent, most reliability estimates do not clearly establish that the data or the experimental conclusions were replicable or unaffected by differences among observers. Suggestions are provided for improving the usefulness of the reliability estimates published in speech-language pathology research.
言语语言病理学中的许多研究和临床工作都依赖于通过直接观察人类行为收集的数据的有效性和可靠性。本文回顾了几种可靠性的定义，得出结论：如果行为观察数据以及从中得出的实验结论不受观察者之间的差异或记录环境中的其他变化的影响，那么这些数据就是可靠的。本文回顾了几种常用于估计观察数据可靠性的方法的理论基础，并从最近一期《言语与听力研究杂志》（1992年第35卷）中选取了这些方法的使用示例。尽管言语语言病理学领域最近的大多数研究出版物都在一定程度上讨论了观察数据的可靠性问题，但大多数可靠性估计并没有明确表明数据或实验结论是可重复的，或者不受观察者之间差异的影响。文中还提供了一些建议，以提高言语语言病理学研究中发表的可靠性估计的有用性。
