Data are presented to support the reliability, validity, and utility of a severity metric for phonological disorders. The metric, percentage of consonants correct (PCC), is readily derived from a continuous speech sample. PCC values are shown to reflect an ordinal severity scale that embraces the constructs of disability, intelligibility, and handicap. PCC values index four levels of "severity of involvement": Mild, mild-moderate, moderate-severe, and severe. The metric provides a means by which instructors, researchers, and speech-language pathologists working in different settings can specify subject descriptions, gauge the effects of intervention programs, and undertake cross-institutional projects. The metric is used as one component of a diagnostic classification system for phonological disorders (Shriberg & Kwiatkowski, 1982a) and within a framework for management of persons with phonological disorders (Shriberg & Kwiatkowski, 1982b), the first and second papers in this series.
本文提供的数据旨在支持一种用于语音障碍严重程度度量指标的可靠性、有效性和实用性。该度量指标为正确辅音百分比（PCC），可轻松从连续语音样本中得出。结果表明，PCC值反映了一个包含残疾、可懂度和障碍等概念的顺序性严重程度量表。PCC值索引了“受累严重程度”的四个级别：轻度、轻中度、中重度和重度。该度量指标为在不同环境中工作的教师、研究人员和言语语言病理学家提供了一种方法，使他们能够明确受试者描述、评估干预项目的效果，并开展跨机构项目。该度量指标被用作语音障碍诊断分类系统（施里伯格和克维亚特科夫斯基，1982a）的一个组成部分，并用于语音障碍患者管理框架（施里伯格和克维亚特科夫斯基，1982b）中，这是本系列的第一篇和第二篇论文。
