Jh. Beitchman et al., 7-YEAR FOLLOW-UP OF SPEECH LANGUAGE-IMPAIRED AND CONTROL CHILDREN - SPEECH-LANGUAGE STABILITY AND OUTCOME, Journal of the American Academy of Child and Adolescent Psychiatry, 33(9), 1994, pp. 1322-1330
Objective: This study examined the 7-year outcome of speech/language (
S/L) impaired and control children selected from a community sample at
age 5 years. Method: Two hundred fifteen children completed a variety
of speech and language tests at age 12 years. Children with S/L impai
rment were further classified as ''speech only,'' ''language only,'' o
r ''speech and language impaired.'' Results: More than 72% of children
who had S/L impairment at age 5 remained impaired at age 12. Children
with both speech and language problems were most likely to remain S/L
impaired; 81% had some kind of S/L impairment at follow-up. Similarly
, children with both expressive and receptive language impairment were
more likely to show expressive or receptive impairment at follow-up t
han children with expressive impairment alone. One third of time 1 con
trols had S/L problems at follow-up, and of these 82% had speech impai
rment only. Conclusions: S/L impairment identified at age 5 has long-l
asting effects. More pervasive problems were associated with poorer ou
tcomes. Screening at age 5 may be useful, as most serious S/L problems
that emerged by middle childhood could be identified at age 5. The ef
fects of S/L treatment require further study.
