Abstract：
BACKGROUND: Communication and language skills are among the most severely affected domains in individuals with autistic spectrum disorder (ASD). When a child diagnosed with ASD lives in a bilingual environment, the parents often express concerns about whether their child should learn both languages simultaneously, turning to specialists for advice. Despite the lack of evidence of any negative effect, some professionals disagree on this subject. In this systematic review we study whether bilingualism affects language development in children with ASD.
METHODS: We reviewed the literature published in 4 different databases. After applying a series of selection criteria, we selected 12 scientific articles, including a total of 328 children diagnosed with ASD (169 bilingual and 159 monolingual), with ages ranging from 3 to 12 years. These patients were evaluated with different receptive and expressive language assessment instruments covering several areas. The assessments were performed directly on the children, although indirect assessment of parents was also performed in some studies.
CONCLUSIONS: There seems to be consensus regarding the assertion that bilingualism does not entail any additional difficulty for language development in children with ASD from the age of 3.

摘要：
背景：沟通和语言技能是自闭症谱系障碍（ASD）患者受影响最严重的领域之一。当被诊断患有ASD的孩子生活在双语环境中时，父母经常担心他们的孩子是否应该同时学习两种语言，向专家寻求建议。尽管缺乏任何负面影响的证据，一些专业人士在这个问题上意见不一。在这篇系统综述中，我们研究了双语是否会影响ASD儿童的语言发展。
方法：我们回顾了在4个不同数据库中发表的文献。应用一系列选择标准后，我们选择了12篇科学文章，包括328名被诊断患有ASD的儿童（169名双语和159名单语），年龄从3到12岁不等。使用涵盖多个领域的不同接受和表达性语言评估工具对这些患者进行了评估。评估是直接对孩子们进行的，尽管在一些研究中也对父母进行了间接评估.
结论：关于双语不会给3岁以下ASD儿童的语言发展带来任何额外困难的说法，似乎已经达成共识。
