识别有英语以外语言的初级或特定语言障碍（LI）的儿童仍然是一个诊断挑战。本研究探讨了英语和西班牙语的非词重复（NWR），以确定儿童已知有LI的效用。方法：研究对象为4组学龄儿童（N = 187）。有两个典型的发展组：熟练的西班牙语-英语顺序双语和单语英语发言者。有2组LI儿童，一组为西班牙语-英语，另一组为单语英语。孩子们参加了英语和西班牙语NWR。结果儿童的NWR表现在不同语言之间存在显著相关。在英语NWR中，两个LI组在最长音节长度上的准确性低于两个典型发展组。在西班牙语NWR，单语儿童与LI重复准确率低于双语儿童与LI和典型的单语儿童，所有3组优于典型的双语组。似然比表明，只有英语NWR在排除典型的双语儿童显示LI的诊断能力。结论本研究的结果表明，NWR的表现依赖于LI和母语经验的双重影响。然而，NWR仍然可能在LI的复合标记物中有用。
PURPOSE Identifying children with primary or specific language impairment (LI) in languages other than English continues to present a diagnostic challenge. This study examined the utility of English and Spanish nonword repetition (NWR) to identify children known to have LI. METHOD Participants were 4 groups of school-age children (N = 187). There were 2 typically developing groups: proficient Spanish-English sequential bilinguals and monolingual English speakers. There were 2 groups of children with LI, one Spanish-English and the other monolingual English speakers. Children participated in both English and Spanish NWR. RESULTS Children's NWR performance was significantly correlated across languages. In English NWR, the 2 groups with LI had lower accuracy at the longest syllable length than the 2 typically developing groups. In Spanish NWR, monolingual children with LI had lower repetition accuracy than bilingual children with LI and typical monolingual children, with all 3 groups outperformed by the typical bilingual group. Likelihood ratios indicated adequate diagnostic power only for English NWR in ruling out the typical bilingual children as showing LI. CONCLUSION The results demonstrate that NWR performance relies on the dual influences of LI and native language experience. However, it remains possible that NWR is useful in a composite marker for LI.
