Reading skills are necessary for educational development in children. Many studies have shown that children with hearing loss often experience delays in reading. This study aimed to examine reading skills of Persian deaf children with cochlear implant and hearing aid and compare them with normal hearing counterparts.
The sample consisted of 72 s and third grade Persian-speaking children aged 8-12 years. They were divided into three equal groups including 24 children with cochlear implant (CI), 24 children with hearing aid (HA), and 24 children with normal hearing (NH). Reading performance of participants was evaluated by the "Nama" reading test. "Nama" provides normative data for hearing and deaf children and consists of 10 subtests and the sum of the scores is regarded as reading performance score.
Results of ANOVA on reading test showed that NH children had significantly better reading performance than deaf children with CI and HA in both grades (P < 0.001). Post-hoc analysis, using Tukey test, indicated that there was no significant difference between HA and CI groups in terms of non-word reading, word reading, and word comprehension skills (respectively, P = 0.976, P = 0.988, P = 0.998).
Considering the findings, cochlear implantation is not significantly more effective than hearing aid for improvement of reading abilities. It is clear that even with considerable advances in hearing aid technology, many deaf children continue to find literacy a challenging struggle.
阅读技能对儿童的教育发展至关重要。许多研究表明,听力损失儿童往往在阅读方面存在延迟。本研究旨在调查佩戴人工耳蜗和助听器的波斯语聋儿的阅读技能,并将他们与听力正常的同龄人进行比较。
样本包括72名8至12岁讲波斯语的二、三年级儿童。他们被平均分为三组,包括24名佩戴人工耳蜗(CI)的儿童、24名佩戴助听器(HA)的儿童和24名听力正常(NH)的儿童。参与者的阅读表现通过“纳马”阅读测试进行评估。“纳马”为听力正常和失聪儿童提供了标准化数据,由10个分测试组成,分数总和被视为阅读表现分数。
阅读测试的方差分析结果显示,在两个年级中,听力正常的儿童在阅读表现上均显著优于佩戴人工耳蜗和助听器的聋儿(P < 0.001)。使用Tukey检验的事后分析表明,在非单词阅读、单词阅读和单词理解技能方面,佩戴助听器和人工耳蜗的组之间没有显著差异(分别为P = 0.976、P = 0.988、P = 0.998)。
基于这些发现,人工耳蜗植入在提高阅读能力方面并不比助听器显著更有效。显然,即使助听器技术有了长足的进步,许多聋儿在识字方面仍然面临着具有挑战性的困难。
