However, most studies of PSD have reported on participants at 8–9 years of age but have not followed these individuals into adolescence. Risks for persisting impairment in these ability domains in individuals with early childhood SSD include comorbid language impairment (LI), persistent speech disorder (PSD), poor phonological awareness skills, lower nonverbal cognitive abilities, motor impairment, and social disadvantage ( Larrivee & Catts, 1999 Lewis et al., 2015 Wren, Miller, Peters, Emond, & Roulstone, 2016). Children with preschool histories of speech sound disorders (SSD) present with differing longitudinal trajectories and variable long-term outcomes for speech, language, and academic skills.
