Phonological Disorders I

Abstract

Data are presented to support the validity and utility of a diagnostic classification system for persons with phonological disorders. Rationale for the classification system is developed from current reviews of issues and concepts in phonology and classification systems. The system proceeds from a worksheet for reduction of phonological and other assessment data, through five hierarchical levels of classification entries. The system will accommodate lower-level elaboration of etiological subgrouping, pending appropriate research. A retrospective classification study of 43 children with delayed speech is described. Procedural details relating classification procedures to two companion papers (Shriberg & Kwiatkowski, 1982a, 1982b) are provided.
