The development of an expressive language score for people with autism based on the ADOS-2 was recently reported by Mazurek et al. (2019). The current study examined the construct validity of the ADOS-2 expressive language score (ELS) in a sample of adolescents with fragile X syndrome (n = 45, 10 girls), a neurodevelopmental disorder with high rates of autism symptomology. The ADOS-2 ELS showed strong convergent validity with multiple assessments of expressive language, receptive language, and nonverbal cognition. Divergent validity was demonstrated between the expressive language score and chronological age, symptoms of anxiety/depression, and rule-breaking behaviors. This expressive language score is a promising measure of expressive language ability that can be used in research when other language assessments are unavailable.

脆性 X 综合征中 ADOS-2 表达性语言评分的检查。

Mazurek 等人最近报道了基于 ADOS-2 的自闭症患者表达性语言评分的发展。（2019）。目前的研究检查了 ADOS-2 表达性语言评分 (ELS) 在患有脆性 X 综合征（n = 45，10 名女孩）的青少年样本中的结构有效性，这是一种具有高自闭症症状发生率的神经发育障碍。ADOS-2 ELS 在表达性语言、接受性语言和非语言认知的多项评估中显示出很强的收敛效度。在表达性语言分数和实际年龄、焦虑/抑郁症状和违反规则的行为之间证明了不同的有效性。这种表达语言分数是一种很有前途的表达语言能力的衡量标准，当其他语言评估不可用时，它可以用于研究。
