療育開始が生後12ヵ月未満の難聴児の療育効果について検討を行った.対象とした難聴児39名は聴力80~115dBで, 同一の通園施設で聴覚―口話法による療育を受けている.療育開始年齢を基に難聴児を0歳群6名, 1歳群19名, 2歳群14名に分け, 6歳時点でWPPSI知能検査結果を基に各群の比較を行った.さらに施設での療育修了後, 追跡できた難聴児30名 (0歳群6名, 1歳群14名, 2歳群10名) について, WISC III知能検査結果を基に各群の比較を行った.6歳時点のWPPSI知能検査結果およびWISC III知能検査 (評価年齢7~15歳) によると, 各群は聴力および動作性IQには差がないものの, 言語性IQは年齢とともに低下する傾向があり, 0歳群の言語性IQ (WPPSI検査平均98) は2歳群の言語性IQ (WPPSI検査平均77) に比べ有意に高かった.この結果から, 12ヵ月未満の乳児期からの早期療育は明らかに効果のあることが判明した.

This study was designed to examine the effect of entry age of intervention in congenital hearing-impaired children, who had participated in an auditory-oral early intervention program. According to age at entry into the program, we divided the 39 children into three groups: a group of 6 early identified children (entry age: 5-11 months), a group of 19 children with entry ages of 15-22 months, and a group of 14 children with entry ages of 24-34 months. The hearing loss averages of these children ranged from 80 to 115 dB. We measured their language abilities using the WPPSI Intelligence Test at 6 years of age, and using the WISC III Intelligence Test after 6 years of age (range: 7-15 years) .<BR>There were no significant differences in hearing loss degrees or performance IQ scores on the two intelligence tests among the three groups. The verbal IQ scores on the two tests were related to the entry ages in the intervention program. Children enrolled in the program under 12 months demonstrated significantly better verbal IQ scores on the two tests than children enrolled after 24 months of age.<BR>The results of this study provided clear evidence of the benefit of early intervention on the development of language abilities in hearing-impaired children under 12 months of age.
