PURPOSE: to compare the generalization inside of a sound class and for other sound classes in the treatment of subjects with different severity levels of phonological disorders submitted to the Modified Cycles Model, ABAB-Withdrawal and Multiple Probes and Maximum Opposition Model. METHODS: 21 children with phonological disorder, 11 males and 10 females, with average age 5:7, were their speech data analyzed through the phonological assessment. From the contrastive analysis we calculated the Percentage of Correct Consonants (Shriberg & Kwiatkowski, 1982) and the subjects were classified in the different severity levels of phonological disorders: severe, moderate-severe, mild-moderate and mild. Six subjects were submitted to the treatment with Modified Cycles Model, eight to the ABAB-Withdrawal and Multiple Probes Model, and seven to the Modified Maximum Opposition Model. After this was compared the generalization inside of a sound class and for other sound classes among three therapy models for each severity level of phonological disorder. RESULTS: the generalization inside a sound class occurred in all studied models. ABAB-Withdrawal and Multiple Probes Model were effective for all severity groups and the Modified Maximum Opposition were more effective for the severe and moderate-severe groups. In the generalization for other sound classes, the subjects treated with ABAB-Withdrawal and Multiple Probes Model showed a major generalization in different severity levels of phonological disorder. CONCLUSION: all the subjects showed evolution in all kinds of generalization studied in three different therapeutic models.
