目的对于患有发展性语言障碍 (DLD) 的双语儿童，语言治疗反应是指个别儿童在两种语言方面的进步程度。了解预测个体儿童语言治疗反应的因素可以帮助临床医生更有效地计划治疗。 方法本研究是对 Ebert 等人的研究数据的回顾性分析。 （2014）。参与者包括 32 名患有 DLD 的学龄西英双语儿童，他们完成了强化语言治疗计划。西班牙语和英语的进步是使用每种语言的原始测试分数来衡量的。语言增益的预测因素包括语言、认知和人口统计变量。为了检查哪些预测因子是显着的，我们计算了潜在预测因子与治疗后语言测试分数之间的部分相关性，并控制了治疗前测试分数的影响。结果在西班牙语中，几个预测因子与结果测量相关。在控制治疗前分数后，英语语法、女性性别、处理速度、年龄和流体推理与西班牙语治疗后分数相关。在英语中，与个体预测变量的相关性很小。在控制治疗前分数后，只有一个变量与一种英语治疗后分数相关：英语语法。结论最初的研究报告称，与英语的强劲增长相比，西班牙语的增长有限。鉴于美国缺乏对西班牙语的环境支持，西班牙语的治疗反应变化更大。因此，个体因素（包括非语言认知、治疗前语言水平和人口统计变量）会影响西班牙语的治疗效果。相比之下，对英语的强大环境支持支持更一致的治疗反应，个体因素的作用较小。补充材料https://doi.org/10.23641/asha.21991931
PurposeFor bilingual children with developmental language disorder (DLD), language treatment response is the degree to which an individual child progresses in both of their languages. Understanding what predicts language treatment response for an individual child can help clinicians plan treatment more effectively.MethodThis study is a retrospective analysis of data from the study of Ebert et al. (2014). Participants included 32 school-age Spanish–English bilingual children with DLD who completed an intensive language treatment program. Gains in Spanish and English were measured using raw test scores in each language. Predictors of language gains include language, cognitive, and demographic variables. To examine which predictors were significant, we calculated partial correlations between the potential predictors and the posttreatment language test scores, controlling for the effects of pretreatment test scores.ResultsIn Spanish, several predictors correlated with the outcome measures. After controlling for pretreatment scores, English grammaticality, female sex, processing speed, age, and fluid reasoning were related to Spanish posttreatment scores. In English, correlations with individual predictors were minimal. After controlling for pretreatment scores, only one variable was associated with one English posttreatment score: English grammaticality.ConclusionsThe original study reported limited gains in Spanish compared to robust gains in English. Treatment response in Spanish is more variable given the lack of environmental support for Spanish in the United States. As a result, individual factors (including nonverbal cognition, pretreatment language levels, and demographic variables) influence treatment gains in Spanish. In contrast, strong environmental support for English supports a more consistent treatment response, with a smaller role for individual factors.Supplemental Materialhttps://doi.org/10.23641/asha.21991931
