PurposeThis study examined the frequency of code-switching by Spanish-English-speaking children as a function of language proficiency in each language and diagnosis（developmental language disorder [DLD] or typical language development [DLD]）.MethodSixty-two Spanish-English-speaking children，5-7 years old，participated in this study（24 with DLD and 38 with DLD）.语言样本被用来确定每种语言的语言熟练程度，作为一个连续的表现。进行相关分析，以评估西班牙语和英语语言能力与语码转换频率之间的关系，考虑到语码转换单词的总数，句内语码转换（即，具有代码转换部分的句子/C单元的数量），以及插入式代码转换（即，代码转换句子/C单元）。负二项和零膨胀泊松回归进行评估的频率是否代码转换的单词，代码转换的部分，和代码转换的句子是不同的儿童与DLD和他们的同龄人，控制西班牙语和英语proficiency.ResultsWhen西班牙语是目标语言，较低的西班牙语熟练程度与较高的频率代码切换到英语的组与DLD，但是，对于那些不管他们的西班牙语和英语水平如何，都把代码转换成英语的西班牙语和英语的同龄人来说，情况并非如此。诊断对代码转换频率没有统计学显着影响。结论结果表明，DLD儿童及其TLD同龄人的代码转换发生相似;因此，代码转换的频率和类型不应用作DLD的指标。
PurposeThis study examined the frequency of code-switching by Spanish–English-speaking children as a function of language proficiency in each language and diagnosis (developmental language disorder [DLD] or typical language development [TLD]).MethodSixty-two Spanish–English-speaking children, 5–7 years of age, participated in this study (24 with DLD and 38 with TLD). Language samples were used to determine the level of language proficiency in each language as a continuum of performance. Correlational analyses were conducted to evaluate the relationship between Spanish and English language proficiency and the frequency of code-switching considering the total number of code-switched words, intrasentential code-switching (i.e., number of sentences/C-units with code-switched parts), and intersentential code-switching (i.e., code-switched sentences/C-units). Negative binomial and zero-inflated Poisson regressions were conducted to evaluate whether the frequency of code-switched words, code-switched parts, and code-switched sentences is different across children with DLD and their peers with TLD, controlling for Spanish and English proficiency.ResultsWhen Spanish was the target language, lower proficiency in Spanish was associated with higher frequency of code-switches to English for the group with DLD, but not for their peers with TLD who code-switched to English regardless of their Spanish and English proficiency. There were no statistically significant effects of diagnosis on the frequency of code-switches.ConclusionResults indicate that code-switching occurs similarly across children with DLD and their peers with TLD; therefore, the frequency and type of code-switches should not be used as an indicator of DLD.
