PURPOSE: to analyze the relationship between the degree of speech intelligibility and social communication skills in children diagnosed with phonological disorders. METHOD: the study included 10 children diagnosed with phonological disorders, with an average chronological age of 7.28 years and three females and seven males, performing speech-language therapy twice a week in a nursing school in a medium-sized town in the state of São Paulo. The children were assessed by the phonology of the ABFW instrument, and the severity of phonological disorder was based on the Percentage of Consonants Correct (PCC). And then they were video-typed in interaction structures situations in such a way as to obtain a sample of spontaneous speech, in order to characterize the degree of speech intelligibility (GIF), in addition to observing the presence or absence of the components of social communication skills (HSC). In order to examine the relationship between GIF and HSC we used the Spearman coefficient. RESULTS: it was possible to characterize HSC classes that are deficient in children with phonological diagnostic, and to check a significant and positive relationship between GIF and HSC, showing that the higher GIF is the greater are the difficulties in HSC. CONCLUSION: this study examined the relationship between GIF and HSC, and identified classes of HSC that are deficient in children diagnosed with phonological disorders, promoting the development of instruments for assessment and intervention, thus allowing better planning for each case.
