Comparison between the classification based on features and percentage of correct consonants in speech disorders

PURPOSE:

to observe the differences between the ratings of severity of phonological disorders obtained by Percentage of Correct Consonants-Reviewed and the classification based on qualitative traits.

METHODS:

data were collected on pre speech therapy 38 subjects in their phonological systems were classified according to the quantitative assessment of Percentage of Correct Consonants-Reviewed (Mild, Mild-moderate, Moderate-severe, Severe deviation) and qualitative assessment based on features (Mild, Moderate, Moderate-severe, Severe deviation). Data were analyzed by frequency tables and through the chi-square test statistical (p <0.05).

RESULTS:

the overall gave a poor correlation between the results obtained with the qualitative and quantitative assessment of phonological disorders, only 34,79% agreement in the ratings. The analysis by degrees of severity were observed that extreme degrees (Mild and Severe), had almost the same classification with both proposals. Unlike what was observed in the intermediate grades.

CONCLUSION:

based on the results underscores the importance of joint evaluations, which combine qualitative with quantitative measures, especially for the differentiation and characterization of intermediate degrees of severity of phonological disorders.
