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.

易碎X综合征的ADOS-2表达语言分数考试。

Mazurek等人最近报道了基于ADOS-2为自闭症患者开发一种表达性语言评分的方法。（2019）。当前的研究在患有脆性X综合征（n = 45，10个女孩）的青少年样本中检查了ADOS-2表达语言评分（ELS）的结构效度，这是一种自闭症症状发生率很高的神经发育障碍。ADOS-2 ELS通过对表达性语言，接受性语言和非语言认知的多种评估，显示出强大的收敛效度。表现力语言得分与时间年龄，焦虑/抑郁症状和违反规则的行为之间表现出不同的效度。此表达语言分数是表达语言能力的一种有前途的度量，可在其他语言评估不可用时用于研究。
