Five conditions for sampling the continuous speech of 12 speech-delayed children were defined and compared. Conditions differed on variables associated with examiner behavior and stimulus materials. General findings of few significant differences associated with sampling conditions support the validity of continous speech sampling for phonologic…

Data are presented to support the reliability, validity, and utility of a procedure to assess the severity of a phonological disorder. The severity metric, the percentage of consonants correct (PCC), is readily derived from a continuous speech sample. PCC values index four levels of severity of involvement: mild, mild-moderate, moderate-severe,…

A conceptual framework for management of phonological disorders is proposed. The framework includes a 10-element system for describing the structure of management programs and invokes a diagnostic classification system for determining appropriate management content. Data from three serial studies of management structure describe four modes of…

A diagnostic classification system for phonological disorders is presented which is oriented to the goals of explanation, prediction, and management. Data supporting the validity and utility of the system are also provided, based on a retrospective classification of 43 children with delayed speech. (Author/SEW)
