目的：在这项研究中，作者检查了一部分患有唐氏综合症 (DS) 和脆性 X 综合症 (FXS) 的高度语言表达青少年和年轻人的语言表达能力，以寻找与综合症相关的差异的证据。还以探索性方式检查了 FXS 性别差异。 方法：作者评估了 24 名患有 DS 的青少年和年轻人、17 名患有 FXS 的青少年和年轻人以及 21 名具有典型发育 (TD) 的儿童，各组的非语言心理年龄相匹配。使用口语和书面语言量表（OWLS；Carrow-Woolfolk，1995）和发展句子评分（DSS；Lee，1974）从口头叙述语言样本中得出的分数来检查语言能力。 结果：研究分析揭示了以下组间差异：FXS 组在 OWLS 测量中优于 DS 和 TD 组； TD 组在某些 DSS 指标上的表现优于其他组； FXS 组在 DSS 句子点测量上优于 DS 组；患有 FXS 的女性在多项指标上优于患有 FXS 的男性。结论：结果有助于 DS 患者和 FXS 患者的语言表型的持续构建，并支持这样的结论：他们的表达性语言特征存在数量而非质量差异。
Purpose: In this study, the authors examined the expressive language abilities of a subset of highly verbally expressive adolescents and young adults with Down syndrome (DS) and those with fragile X syndrome (FXS) for evidence of syndrome-related differences. FXS gender differences were also examined in an exploratory fashion.Method: The authors evaluated 24 adolescents and young adults with DS, 17 adolescents and young adults with FXS, and 21 children with typical development (TD), with the groups matched on nonverbal mental age. Language ability was examined using the Oral and Written Language Scales (OWLS; Carrow-Woolfolk, 1995) and Developmental Sentence Scoring (DSS; Lee, 1974) scores derived from an oral narrative language sample.Results: Study analyses revealed the following group differences: The FXS group outperformed the DS and TD groups on the OWLS measure; the TD group outperformed both other groups on some of the DSS measures; the FXS group outperformed the DS group on the DSS Sentence Point measure; and females with FXS outperformed males with FXS on several measures.Conclusions: Results contribute to the ongoing construction of the language phenotypes of individuals with DS and individuals with FXS and support the conclusion that there are quantitative rather than qualitative differences in their expressive language profiles.
