Phonological ReorganizationA Qualitative Measure of Phonological Improvement

Qualitative improvement was observed following treatment in one child with a phonological disorder, although little to no quantitative change was noted. Detection of the qualitative changes required both independent and relational analyses, as presented in this article. The broad sampling technique used for these analyses is capable of detecting qualitative change regardless of an a priori theoretical approach. The clinical and theoretical implications of these findings are presented.
