Prelinguistic Communicative Factors Discriminating between Developmental Language Delay and Typical Language Development at 2 Years in Preterm Toddlers

국문 초록 (Abstract)

배경 및 목적: 언어이전기 의사소통 행동은 언어발달지체와 정상언어발달을 판별하는 주요한 요인이다. 본 연구의 목적은 2세 미숙아 집단에서 언어발달지체와 정상언어발달을 판별하는 가장 중요도 높은 요인이 무엇인지 밝히고자 하였다. 방법: 대상자는 미숙아로 출생한 영유아 47명이었다. 대상자들은 언어검사 결과에 따라 ‘정상-정상’집단, ‘지체-정상’집단, ‘지체-지체’집단으로 분류되었다. 양육자와의 자유놀이 상황에서 영유아의 의사소통 행동을 수집하였고, 수집된 의사소통 행동 표본에서 의사소통 행동 빈도와 유형수, 몸짓 빈도와 유형수, 발성 빈도와 자음 유형수를 측정하였다. 결과: ‘지체-지체’집단은 유의하게 낮은 의사소통 행동, 몸짓, 발성의 빈도를 보였고, 유의하게 적은 수의 자음을 산출하였다. 판별분석 결과 몸짓 빈도, 의사소통 행동 빈도, 자음 유형수가 미숙아 집단 내 ‘지체-정상’과 ‘지체-지체’집단을 판별하는데 가장 중요도 높은 요인이었다. 논의 및 결론: 연구결과에 따라 미숙아 집단의 언어발달지체와 정상언어발달을 판별해주는 언어이전기 의사소통 행동에 대하여 논의하였다.

Objectives: Prelinguistic communicative behaviors are important discriminating factors discriminating language delay from typical development. The purpose of this study was to examine the prelinguistic communicative behavior that most effectively distinguish the DLD from TD at 2 years in preterm toddlers. Methods: The participants were 47 preterm toddlers with a first evaluation at 15 to 18 months and a second at 24 months. Based on the assessment results, the participants were classified into 3 groups: ‘typical- typical’, ‘delay- typical’, and ‘delay-delay’. The frequency and type of intentional communicative behavior, the frequency and type of gestures, the frequency of vocalizations, and the types of consonants were measured from the behavior samples that were collected during freeplay with caregiver. Discriminant analysis was conducted for identifying factors to discriminate between DLD and TD. Results: The ‘delay-delay’ group showed a significantly lower frequency of intentional communicative behavior, gestures, vocalizations, and a lower number of consonants. The results of discriminant analysis indicated that the frequency of gestures and intentional communicative behavior, the types of consonants were most significant to discriminate the subsequent presence of language delay in preterm toddlers. Conclusion: We discuss the prelinguistic communication factors for distinguish the DLD group from TD in preterm toddlers based on these results.
