Phonological awareness, or consciousness of speech sounds and operational skill with them, develops in the order word > syllable > phoneme, over the ages of four to seven. Among the various types of phonological awareness tasks, the deletion task has a higher level of difficulty because it requires operation and deletion of sounds within words. This task also has a high correlation with reading proficiency. This study utilized a deletion task with 20 questions to see how operational development depended on age and gender. The deletion task, with 20 questions, was tested on four- to six-year old children developing normally (N = 90). The results showed that phonological awareness performance improved with age. This age effect was not accompanied by a gender effect; age and gender interacted. The study confirmed the development of phonological awareness in four- to six-year-old children who were developing normally. The deletion task can be used to effectively detect the risk of difficulties with phonological awareness in preschoolers with speech, language, and reading problems.

배경 및 목적 : 본 연구의 목적은 우리나라 6세 아동의 말소리 산출능력의 발달과 말소리장애 출현율을 알아보기 위한 것이다. 인구역학적 조사를 위해 우선 성별, 출생순위, 어머니 학력, 거주지역 크기에 따른 말소리 산출점수와 장애 출현율을 조사하였다. 방법: 한국아동패널에서 수집한 7차 데이터의 중 1,503명의 발화자료를 분석하였다. 발화자료는 말소리선별검사로 개발된 세 문장 따라말하기 과제로 아동의 평균연령은 6.3세이며 남아의 비율은 51%이다. 결과: 성별에 따른 차이에서 여아의 말소리 오류가 남아보다 적었으며, 여아의 출현율이 더 낮았다. 출생순위가 빠른 아동이 늦은 아동보다 말소리 오류가 적었으며 출현율이 더 낮았다. 성별과 출생순위는 통계적으로 유의미한 차이를 보였다. 어머니 학력이 높을수록 말소리 오류가 적었으며 출현율도 낮았다. 도시지역이 읍/면 지역보다 말소리 오류가 적었으며 출현율도 낮았다. 그러나 어머니학력과 주거지역 크기는 통계적으로 유의미한 차이를 보이지 않았다. 논의 및 결론: 확실한 말소리장애는 2.5%, 의심되는 경우가 6.4%로 전체에서 9%의 아동이 말소리문제가 있는 것으로 나타났다. 향후 말소리장애에 영향을 미칠 수 있는 다른 매개변수들에 대한 연구 및 종단연구의 필요성을 제안하였다. Objectives : The prevalence of a public health problem is a key statistic in the allocation of funds for research and public services. This study investigated 6-year-old Korean children’ speech production skills and the prevalence of speech sound disorders (SSD) in relation to demographic factors (gender, birth order, mother’s education background, and residence area size) that are known to influence speech sound development. Methods: Data from 1,503 children was collected for the Korean Child Panel Study conducted by the Korea Institute of Child Care and Education. The participants’ average age was 6.3 years (51.2% boys and 48.8% girls). To assess their articulation, the ‘3 Sentence-Screening-Test’ was administered to each of the children. Results: The primary findings are as follows. In relation to gender, the prevalence of SSD was significantly higher in boys than girls with 2.8% (at-risk 7.9%) in boys and 1.7% (at-risk 4.6%) in girls. As for the occurrence of speech sound errors in relation to birth order, significantly increased errors and prevalence were found in later births. The prevalence of SSD in relation to mothers’ educational backgrounds tends to decrease with higher academic ability but did not show a statistically significant difference. In relation to residence size, the prevalence of SSD was more frequent in children residing in rural area than children residing in urban area, but the difference was not statistically significant. Conclusion: The prevalence of SSD (moderate to severe) in Korean 6-year-old children was 2.5%. Implications of these findings are discussed.

Phonological Awareness and Vocabulary Characteristics of Children with Speech Sound Disorders

배경 및 목적: 말소리장애 아동은 동반하고 있는 문제가 다양한 이질적인 집단이다. 특히 말소리장애 아동이 동반하고 있는 문제 중 언어, 어휘, 음운인식의 문제는 이후 문해 기술을 예측하고 문제를 예방하는데 중요한 요인이다. 따라서 본 연구는 말소리장애 아동의 문해 기술과 관련된 음운인식과 어휘 특성을 살펴보고 음운인식, 어휘, 자음정확도 간 상관관계를 살펴보고 말소리장애 아동이 음운인식과 어휘에서 지연을 보이는 비율을 살펴보고자 하였다. 방법: 일반 아동과 말소리장애 아동 각각 24명씩을 대상으로 말소리, 음운인식, 어휘 능력을 평가하였다. 결과: 연령과 말소리장애 유무에 따라 음운인식, 어휘 능력에 유의미한 차이가 나타났으며, 음운인식이 자음정확도보다 어휘 능력과 더 큰 상관을 보였다. 말소리장애 아동 중 음운인식과 어휘에서 모두 지연을 보이는 비율은 33%, 음운인식만 지연을 보이는 비율은 16%, 어휘만 지연을 보이는 비율은 16%, 순수한 말소리장애의 비율은 33%로 나타났다. 논의 및 결론: 말소리장애 아동이 동반하고 있는 문제의 특성을 확인하고 차별적인 평가와 중재의 필요성을 제안하였다. Objectives: Phonological awareness (PA) skills and vocabulary knowledge are known to be significant predictors of later reading and literacy skills. There have been inconsistent reports about PA, characteristics of vocabulary, and their influences on literacy for children with speech sound disorders (SSD). The aim of this study is to investigate whether there are any differences in PA and vocabulary skills between SSD children and typically developing children (TD). Methods: The subjects were 24 TD children and 24 SSD children between 5 and 6 years old. These children were tested on articulation ability (percentage of correct consonants [PCC]), PA, and vocabulary skills. Results: The results are as follows. First, statistically significant differences were found in PA and vocabulary skills between age groups and SSD/TD groups. Second, PA skills had a stronger correlation with vocabulary knowledge than articulation ability (PCC). Thirty-three percent of SSD children showed delay in both PA and vocabulary. Sixteen percent of SSD children showed delay in phonological awareness only, and 16% of SSD showed delay in vocabulary skills only. Lastly, 33% of SSD children were considered to be pure SSD with no delay in any tested area. Conclusion: The researchers suggest that differential evaluation and intervention are crucial for SSD children with accompanying difficulties in PA and vocabulary skills. For SSD children with delay in PA and/or vocabulary skills, direct intervention and continued monitoring of early literacy skills should be required to prevent potential future literacy difficulties.

Purpose: Some studies suggest that children with SSD frequently have language impairments as evidence of correlation between speech and language abilities. The purpose of this study is to investigate the distribution of children with SSD according to the presence or absence of a language impairment. Methods: In this study, language tests were conducted on 92 four- to six-year-old children with SSD. These children were dividing into four groups, i.e., only SSD, receptive delay, expressive delay, and receptive and expressive delay groups, and the comorbidity rate of speech sound disorder and language impairment by age, gender and severity was examined for each group. Results: First, the rate of children with SSD that accompanied language impairments was shown to be 57.8%, and among them, receptive and expressive delay accounted for the highest rate. Second, only the SSD group showed no significant differences in gender, but female children showed a higher comorbidity rate with receptive and expressive delay, while male children showed a higher comorbidity rate with receptive delay and expressive delay. Third, comorbidity rates with only SSD and receptive and expressive delay increased as age increased, while comorbidity rates with expressive delay decreased as age increased.Comorbidity with receptive delay was shown only in 5-year-olds. Fourth, in the mild and mild/moderate groups, only SSD accounted for the highest rate. However, in the moderate group, expressive delay accounted for the highest rate.Conclusions: Children with SSD showed differences in comorbidity rate with language impairment based on age, gender, and severity. This provided an important basis for verifying the characteristics of language issues in children with SSD by age, gender, and severity.
