Academic Outcomes in Children with Histories of Speech Sound Disorders

Tests of phonology, semantics, and syntax were administered to 52 preschool children (19 girls and 33 boys, age 4-6 years) with moderate to severe speech sound disorders. The children's performance on these tests was used to predict language, reading, and spelling abilities at school age (age 8-11 years). Language impairment at school age was related to poor performance on preschool tests of syntax and nonsense word repetition, while reading impairment was predicted by poor performance in all preschool test domains (phonology, semantics, and syntax). In contrast, spelling impairment was predicted by deficits in preschool tests of phonological processing as measured by the Word Discrimination subtest of the Test of Language Development - Primary 2. Family history for speech and language disorders did not predict language, reading, or spelling impairment at school age. However, family history for reading disorders was a good predictor of school-age spelling difficulties.
