Language Ability to Predict Subtypes of Speech Sound Disorder

Objectives: The purpose of this study is to investigate whether there are differences in vocabulary, grammar, pragmatics, and early literacy skills according subgroups speech sound disorders (SSDs). Additionally, attempted examine language ability could predict the subtype SSDs suggested by Dodd’s model for differential diagnosis. Methods: Sixty-two children with aged 3-9 years were classified into groups articulation (AD), phonological delays (PD), consistent/inconsistent (CPD/IPD). Vocabulary grammar evaluated, pragmatics was evaluated based on parental reports. Results: Children exhibited significant receptive/expressive reading performance; but no found writing. In general, AD showed significantly better performance than within other SSD subgroups, IPD lowest performance. This that best predictor subtypes most vulnerable SSDs. Conclusion: investigating examining all aspects - suggests reception expression should be clinical field.
