[Severity of phonological disorders: perceptual judgment and percentage of correct consonants].

BACKGROUND Phonological disorder. AIM To apply the percentage of correct consonant (PCC) index and to verify the correlation between this index and the one applied perceptually by judges. METHOD The PCC index of 50 phonological disordered subjects was calculated, after 60 judges heard the phonological tests for each subject and perceptually attributed the severity. RESULTS The PCC index varied from 40% to 98%, with the predominant classification of the population in the mild and mild-moderate levels. CONCLUSION A correlation between the perceptual judgment and the PCC indexes exists.
