PURPOSE: The aim of this study was to evaluate metaphonological changes in children with phonological disorder (PD) to compare the outcomes of 2 different treatment methodologies, - Metaphon and Minimal Pairs therapy-, and to highlight changes in phonological awareness (PA) post treatment. CASE REPORT: The study sample included 4 subjects (S1, S2, S3, and S4) aged between 4:6 and 7:0.S1 and S2, both women, were treated according to the Metaphon Theory whereas S3 and S4, both men, were treated using the Minimal Pairs Approach. In the pretreatment period, phonological and other evaluations were performed to diagnose PD. Phonological awareness was evaluated before and after treatment. Analysis of PA showed improvements in all 4 subjects. However, S3 (treated with the Minimal Pairs therapy) was not able to accomplish tasks at the phonemic awareness level, even though this was expected at his age. All the subjects showed improved syllabic awareness; however, S3 was could not complete the phonemic awareness tasks (the only 1 who was apt to accomplish them). CONCLUSION: This suggests that the Minimal Pairs approach may not benefit phonemic awareness as efficiently as Metaphon therapy.
