Neurodevelopmental problems and quality of life in 6-year-olds with a history of developmental language disorder

To explore family-reported neurodevelopmental functioning and quality of life in 6-year-olds who had screened positive for developmental language disorder at age 2.5 years.

Parents of 85 6-year-old children completed questionnaires about child neurodevelopmental difficulties and quality of life. The children were interviewed regarding quality of life, and their language was assessed by speech and language pathologists. Test results at 6 years identified three subgroups: children with developmental language disorder (n = 68) or speech sound disorder (n = 6) and children with no current language disorder (n = 11).

Out of the 68 children with developmental language disorder, 33 (48%) had significant parent-rated problems with language, executive functions 17 (25%), perception 15 (22%) and/or motor skills 15 (22%). Four (67%) of the children with speech sound disorder had significant problems with language. Significant problems were reported with language in five (45%) and with perception in four (36%) children with no current language disorder. The parents reported no impaired quality of life, whereas the children themselves reported impairment mainly with school functioning.

Overlap between language difficulties and other neurodevelopmental problems was higher in 6-year-olds who had screened positive for developmental language disorder about 3 years earlier, than in the general population. The parent and child reports of quality of life were not consistent.
