배경 및 목적: 일반아동과 말소리장애 아동을 대상으로 조음 일관성의 발달 패턴과 특징을 살펴보고, 비일관적인 말소리장애를 감별 진단할 수 있는 점수 체계와 기준점을 제시하고자 하였다. 방법: 2세 전반에서부터 9세까지의 일반 또는 말소리장애 아동 524명을 대상으로 22개의 낱말을 3번씩 산출하게 한 뒤 조음 일관성 점수를 구하였다. 연령과 집단에 따라 조음 일관성 점수가 어떠한지 살펴보고 전체 대상자의 일관성 점수를 토대로 비일관적 말소리장애 집단을 진단할 수 있는 기준점을 찾고자 하였다. 결과: 연령과 집단에 따라 일관성 점수가 유의한 차이를 보였으며, 상호작용은 통계적으로 유의하지 않았다. 일반과 말소리장애 아동 모두 연령이 증가함에 따라 정확하고 일관된 조음을 보였다. 특히 3-4세 사이에 일관성 점수가 유의하게 증가하여 2-3세 아동과 4-6세 아동의 구별된 조음 일관성을 보였다. 전체 대상자의 일관성 점수 백분위수 자료를 토대로 본 연구에서 사용한 검사도구를 사용하여 비일관적인 말소리장애를 진단할 때 참조할 수 있는 규준을 제안하였다. 하위 5%에 해당하는 27점을 발달적 변이성과 병리적인 비일관성을 구분하는 기준점으로 정하였다. 논의 및 결론: 본 연구는 말소리장애의 하위유형을 구별하여 진단할 수 있는 기반을 마련하였으며, 제안된 기준점이 비일관적인 말소리장애를 포함하여 말소리장애 하위유형을 정확하고 타당하게 구별하는지 추후 검증해야 한다.
영문 초록
Objectives: This study aimed to examine developmental patterns of articulatory consistency in typically developing children and children with speech sound disorders, and to identify a cutoff score for differentiating between normal variation and inconsistent productions. Methods: This study included 524 children aged between 2;0 and 9;11. They were asked to produce 22 words on three separate occasions. Consistency scores were calculated based on the phonetic transcription of each response. Statistical analyses were performed to investigate whether consistency was different across age groups between typically developing children and children with speech sound disorders and to identify a cutoff score for differentiating inconsistency from normal variation. Results: The results showed that there were significant main effects and no interaction effect between age and groups. Both typically developing children and children with speech sound disorders showed higher accuracy and consistency of articulation as they grow up. In particular, consistent scores of 4- to 6-year-old children were significantly higher than those of 2- and 3-year-old children. Children’s word productions were highly consistent at 4.5 years of age. This study suggested that a cutoff score of 27 could be used to differentiate inconsistent speech sound disorders from typical speech sound development and other types of speech sound disorders. Conclusion: This study suggested a foundation for differential diagnosis of speech sound disorders. Further investigations are needed to test the sensitivity and specificity of the cutoff score for differential diagnosis of speech sound disorders.
