Children with histories of early phonology disorders were assessed at
school age for both spoken language and written expression skills. Res
ults showed that children with a history of a phonology disorder perfo
rmed more poorly on writing tasks than siblings developing normally. C
hildren with histories of phonology disorders + additional language di
sorders performed more poorly on writing tasks than children with hist
ories of phonology disorders alone. Spoken language abilities, as meas
ured by the CELF-R, best predicted written expression skills for both
groups of children with phonology disorders. However, measures of the
semantic and syntactic capacity of spoken language abilities did not c
orrelate with corresponding aspects of written expression.
