PURPOSE
This study documents the risk for language impairment in Latino children who had different levels of exposure to English and Spanish.
METHOD
A total of 1,029 preschool- and kindergarten-age children were screened in the domains of semantics and morphosyntax in both Spanish and English. Parent report was used to document current exposure to and use of Spanish and English, as well as year of first exposure to English. Risk for language impairment was compared for language group, year of first English exposure, age, and mother's education.
RESULTS
While bilingual children's scores on each subtest were significantly lower compared to their functional monolingual peers, they were no more likely to fall in the at-risk range based on a combination of all 4 subtests. Maternal education and year of first English exposure were weakly associated with risk for language impairment but not with language group (via 5 levels of first and second language exposure).
CONCLUSIONS
Prevalence of risk for language impairment when both languages are tested is not related to language group.
目的
本研究记录了英语和西班牙语接触程度不同的拉丁裔儿童语言障碍的风险。
方法
共有 1029 名学龄前和幼儿园年龄的儿童在西班牙语和英语的语义和形态句法领域进行了筛查。家长报告用于记录当前接触和使用西班牙语和英语的情况,以及接触英语的年份。比较语言组、首次接触英语的年份、年龄和母亲教育对语言障碍风险的影响。
结果
尽管双语儿童在每个子测试中的分数明显低于他们功能上的单语同龄人,但根据所有 4 个子测试的组合,他们不太可能处于风险范围内。母亲的教育程度和首次接触英语的年份与语言障碍的风险相关,但与语言组无关(通过 5 个层次的第一语言和第二语言接触)。
结论
当两种语言都进行测试时,语言障碍风险的流行率与语言组无关。
