BACKGROUND: phonological therapy in siblings with phonological disorder. PROCEDURE: the sample was composed of two brothers, S1 and S2, male and female, respectively. S1, age 6:6-year-old, with severe phonological disorder, was treated by Minimal Opposition model and S2, age 4:8-year-old, with moderate-severe phonological disorder, was treated by Maximal Opposition model. Both subjects have had 25 sessions of speech therapy. RESULTS: S2 got better development compared to S1. S1 showed generalization to untreated items and S2 showed generalization within a sound class. CONCLUSION: the used models are effective, because they provided the occurrence of generalizations and the improvement of the phonological system of both subjects. However, environmental factors may have limited the progress of treatment, since that the children had similar substitutions in the speech that favored the maintenance of the change.
