Specific language impairment in childhood is associated with impaired mental and social well-being in adulthood.

To study the possible influence of childhood language impairment on adult life and well-being, 35 persons with a mean age of 34 years filled out two questionnaires. Compared with the general population, subjects more often lived with parents, and were pensioned. Only a few reported having literacy problems, but over 40% had difficulty in finding words and remembering instructions. Childhood performance IQ was associated with education and word-finding difficulties, and verbal IQ with difficulties in remembering instructions. Health-related quality of life was related to literacy skills, finding words, and remembering instructions. In conclusion, adults with childhood language impairment differ markedly from the general population. Problems in expressing themselves and receiving information affect their well-being the most. Childhood performance seems to have some prognostic value for language-based problems in adulthood.
