PURPOSE: to analyze the efficacy in the three models of therapy with phonological basement in subjects with different degrees of phonological disorder severity. METHODS: the subjects in this research were 21 children, eleven males and ten females, with age mean: 5:7. Speech data were analyzed through the performance of the phonological assessment. After the phonological assessment, the percentage of correct consonants proposed by Shriberg & Kwiatkowski (1982) was calculated and the subjects were then classified in the severity degrees regarding the phonological disorder in: severe, moderate-severe, mild-moderate and mild disorder. Six0 subjects were submitted to the Modified Cycles Model, 8 to the ABAB-Withdrawal and Multiple Probes Model and 7 to the Modified Maximum Opposition Model. Making the comparison the generalization to other position in the word among three models of therapy within each degree of phonological disorder severity. RESULTS: the generalization to other position in the word occurred in all the studied models, however, ABAB-Withdrawal and Multiple Probes Model were more effective to the group with severe disorder; the Modified Maximum Opposition Model to the group with moderate-severe and mild-moderate disorder; and the Modified Maximum Opposition and the ABAB-Withdrawal and Multiple Probes Models to the group with mild disorder. CONCLUSION: all the subjects showed gains in the phonological system and relation to generalization of the other positions in the word, but the ABAB-Withdrawal and Multiple Probes and Modified Maximum Opposition Models were more effective.
