目的：发展性语言障碍 (DLD) 的定义是尽管其他方面发育正常，但语言表现却较低，会对儿童的社交和学业成绩产生负面影响。这项研究是第一个检查越南语 DLD 的研究。为了奠定基础，我们确定了越南的 DLD 病例，并探讨了该疾病的语言特定特征。方法：通过对居住在越南河内的 1,250 名幼儿园教师进行评级，来招募有或没有 DLD 风险的儿童。一百四名儿童完成了词汇和语言抽样的直接测量，他们的父母完成了深入的调查。我们研究了跨任务的趋同性和分歧，以确定可以作为可靠风险指标的措施。然后，我们比较了不同能力水平的直接语言测量的表现。结果：教师和家长报告之间以及报告和直接语言测量之间存在正相关。根据各项措施的趋同性，确定了三组：DLD、DLD 有一定风险和无风险。 DLD 组在接受性和表达性词汇、平均话语长度和语法方面表现最低。尽管患有 DLD 的儿童表现出更多的错误，但在 DLD 和无风险组中发现的错误类型相似。结论：与全球发现的比率相似，越南 7% 的幼儿园儿童存在 DLD 风险。结果强调了家长和教师报告的重要性以及识别 DLD 的多种措施的价值。我们用越南语讨论了 DLD 的潜在临床标志物并概述了未来的方向。
Purpose: Developmental language disorder (DLD), defined by low language performance despite otherwise normal development, can negatively impact children's social and academic outcomes. This study is the 1st to examine DLD in Vietnamese. To lay the foundation, we identified cases of DLD in Vietnam and explored language-specific characteristics of the disorder.Method: Teacher ratings of 1,250 kindergarteners living in Hanoi, Vietnam, were used to recruit children with and without risk for DLD. One hundred four children completed direct measures of vocabulary and language sampling, and their parents completed in-depth surveys. We examined convergence and divergence across tasks to identify measures that could serve as reliable indicators of risk. Then, we compared performance on direct language measures across ability levels.Results: There were positive associations between teacher and parent report and between report and direct language measures. Three groups were identified based on convergence across measures: DLD, some risk for DLD, and no risk. The DLD group performed lowest on measures of receptive and expressive vocabulary, mean length of utterance, and grammaticality. Although children with DLD exhibited a greater number of errors, the types of errors found were similar across DLD and No Risk groups.Conclusions: Similar to rates found globally, 7% of the kindergarten population in Vietnam exhibited risk for DLD. Results highlight the importance of parent and teacher report and the value of multiple measures to identify DLD. We discuss potential clinical markers for DLD in the Vietnamese language and outline future directions.
