孤独症患儿听觉异常行为的研究

Study on auditory abnormalities of children with autism

目的:探讨孤独症患儿听觉异常行为的临床特征及其特异性。方法:参照Harrison的《感觉行为量表》和Dunn的《感觉处理能力剖析量表》制定调查表,对156例孤独症患儿和141例对照组语言发育迟缓患儿进行听觉异常行为的调查和比较。结果:孤独症患儿听觉异常行为的发生率为100%,而对照组患儿仅为33.3%;孤独症患儿的听觉异常行为主要包括听觉反应迟钝、听觉反应过敏、听觉恐惧和听觉特殊兴趣。两组患儿各项听觉异常行为发生率比较差异均有统计学意义。结论:听觉异常行为是孤独症患儿的重要表现之一,并具有一定的特异性。了解孤独症患儿的听觉反应特征对于孤独症的早期识别以及进一步了解孤独症的发病机制具有重要的意义。

Objective: To explore the clinical characteristics and specificity of auditory abnormalities in children with autism.Methods: A questionnaire was designed according to Harrison sensory behavior scale and Dunn sensory processing capacity analytical scale to investigate and compare auditory abnormalities of 156 children with autism and 141 children with language development delay(control group).Results: The incidence rates of auditory abnormalities in autism group and control group were 100% and 33.3%,respectively;the types of auditory abnormalities in autism group mainly included auditory hyposensitivity,auditory hypersensitivity,phonophobia and special interests in certain sounds.There was statistically significant difference in incidence rates of variant auditory abnormalities between the two groups.Conclusion: Auditory abnormalities are important manifestations of autism in children,which have a certain specificity.Understanding the characteristics of auditory abnormalities in children with autism has important significance for early identification of autism and further studying the mechanism of autism.
