Classification of Subgroups of Children with Speech Sound Disorders: A Preliminary Study

국문 초록 (Abstract)

배경 및 목적: 말소리장애 아동이 산출한 오류 형태를 기반으로 하위 유형을 나눈 언어학적 증상 모델을 사용하여 우리나라 말소리장애 아동의 하위 유형을 분류하였을 때 분포 경향성이 어떠한 지 알아보고 하위 유형 별로 말·언어 특성을 살펴보고자 하였다. 방법: 3-9세 말소리장애 아동 133명을 오류패턴의 발달성과 말 산출 오류의 일관성을 기준으로 조음장애, 음운지연, 일관적 음운장애, 비일관적 음운장애로 나누었다. 또한 말소리장애 하위 유형 별로 생활연령, 자음정확도, 수용 및 표현 어휘력에 차이가 있는지 살펴보았다. 결과: 말소리장애 아동 중 조음장애 아동이 30.08%, 음운지연 아동이 44.36%, 일관적인 음운장애 아동이 18.05%, 비일관적인 음운장애 집단이 7.52%로 나타났다. 말소리장애 하위 유형에 따라 연령 분포에 유의한 차이가 있었으며 조음장애 아동의 생활연령이 다른 집단에 비해 유의하게 높았다. 말 심각도는 일관적, 비일관적 음운장애 아동이 조음장애와 음운지연 아동에 비해 유의하게 높았다. 수용 및 표현어휘력은 말소리장애 하위 유형 간 차이가 나타나지 않았다. 논의 및 결론: 본 연구는 우리나라 말소리장애 아동을 말 오류 특성을 바탕으로 하위 유형을 분류하였다. 이는 말소리장애 아동을 정확하게 감별 진단하고 유형 별 특성에 맞는 효과적인 중재를 제공하기 위한 기반이 될 것이다.

Objectives: The purpose of this study is to examine the distribution tendency when classifying subgroups of children with speech sound disorders according to linguistic symptomatology, which are divided into subtypes of speech sound disorders based on the error patterns and inconsistency. Methods: Based on the error patterns and consistency of speech production, 133 children aged 3-9 years were divided into 4 groups; articulation disorder, phonological delay, consistent phonological disorder, and inconsistent phonological disorder. In addition, we examined the differences in age, percentage of consonants correct, and vocabulary by subgroups of speech sound disorders. Results: The results showed that of 133 children, 30.08% had an articulation disorder, 44.36% had a phonological delay, 18.05% had a consistent phonological disorder, and 7.52% had an inconsistent phonological disorder. There was a significant difference in age distribution according to subgroups of speech sound disorders, and age of children with articulation disorder was significantly higher than other groups. Speech severity was significantly higher in children with consistent and inconsistent phonological disorders than in children with articulation disorders and phonological delays. Receptive and expressive vocabulary did not differ between subgroups of speech sound disorders. Conclusion: This study examined linguistic symptomatology for differential diagnosis. This will be the basis for accurate differential diagnosis of children with speech sound disorders and provide effective interventions for each subgroups.
