Early identification of hearing loss in young children is essential in order to avoid the potentially disabling effects of deafness. This necessitates effective screening measures with proven positive predictive value (McCormick 1977, 1988; Mahon et al., 1993). Previous studies (Marcuson et al., 1988; Bellman and Marcuson, 1991) have indicated that the E2L Toy Test, designed as a word discrimination test for evaluating the hearing of children who have English as a second language (E2L), could be such a measure. The results of diagnostic audiological testing, including the E2L test, are reported in 264 children. Comparison of E2L results with audiometric testing shows the E2L test to have a sensitivity of 87% and specificity of 90% in identifying children with an average hearing threshold of greater than 25 dB HL (and 78% sensitivity: 94% specificity where the average hearing threshold level is above 20 dB HL). This is the case for both E2L children and for children whose first language is English, suggesting that the E2L Toy Test would be useful in hearing screening test batteries throughout the UK. The results of screening hearing using the E2L Toy Test in 500 children aged 2-7 years from a wide geographical area in the UK are also presented.
早期识别幼儿听力损失对于避免耳聋可能带来的致残影响至关重要。这就需要有效的筛查措施，且这些措施要有经过验证的阳性预测值（麦考密克，1977年、1988年；马洪等人，1993年）。先前的研究（马库森等人，1988年；贝尔曼和马库森，1991年）表明，E2L玩具测试作为一种用于评估以英语作为第二语言（E2L）儿童听力的单词辨别测试，可能就是这样一种措施。本文报告了264名儿童的诊断性听力学测试结果，包括E2L测试。将E2L测试结果与听力测试结果进行比较发现，在识别平均听力阈值大于25 dB HL的儿童时，E2L测试的灵敏度为87%，特异度为90%（当平均听力阈值水平高于20 dB HL时，灵敏度为78%，特异度为94%）。对于E2L儿童和以英语为母语的儿童都是如此，这表明E2L玩具测试在全英国的听力筛查测试组合中都将很有用。本文还展示了在英国广泛地理区域内对500名2至7岁儿童使用E2L玩具测试进行听力筛查的结果。
