C. Yoshinagaitano et al., LANGUAGE OF EARLY-IDENTIFIED AND LATER-IDENTIFIED CHILDREN WITH HEARING-LOSS, Pediatrics (Evanston), 102(5), 1998, pp. 1161-1171
Objective. To compare the language abilities of earlier- and later-ide
ntified deaf and hard-of-hearing children. Method. We compared the rec
eptive and expressive language abilities of 72 deaf or hard-of-hearing
children whose hearing losses were identified by 6 months of age with
78 children whose hearing losses were identified after the age of 6 m
onths. All of the children received early intervention services within
an average of 2 months after identification. The participants' recept
ive and expressive language abilities were measured using the Minnesot
a Child Development Inventory. Results. Children whose hearing losses
were identified by 6 months of age demonstrated significantly better l
anguage scores than children identified after 6 months of age. For chi
ldren with normal cognitive abilities, this language advantage was fou
nd across all test ages, communication modes, degrees of hearing loss,
and socioeconomic strata. It also was independent of gender, minority
status, and the presence or absence of additional disabilities. Concl
usions. Significantly better language development was associated with
early identification of hearing loss and early intervention. There was
no significant difference between the earlier- and later-identified g
roups on several variables frequently associated with language ability
in deaf and hard-of-hearing children. Thus, the variable on which the
two groups differed (age of identification and intervention) must be
considered a potential explanation for the language advantage document
ed in the earlier-identified group.
