In this study we seek evidence of validity according to the socio-cognitive framework (Weir, 2005) for a new sentence repetition test (SRT) for young Deaf L1 Swiss German Sign Language (DSGS) users. SRTs have been developed for various purposes for both spoken and sign languages to assess language development in children. In order to address the need for tests to assess the grammatical development of Deaf L1 DSGS users in a school context, we developed an SRT. The test targets young learners aged 6–17 years, and we administered it to 46 Deaf students aged 6.92–17.33 (M = 11.17) years. In addition to the young learner data, we collected data from Deaf adults (N = 14) and from a sub-sample of the children (n = 19) who also took a test of DSGS narrative comprehension, serving as a criterion measure. We analyzed the data with many-facet Rasch modeling, regression analysis, and analysis of covariance. The results show evidence of scoring, criterion, and context validity, suggesting the suitability of the SRT for the intended purpose, and will inform the revision of the test for future use as an instrument to assess the sign language development of Deaf children.

瑞士德语手语句子重复测试的有效性证据

在这项研究中，我们根据社会认知框架 (Weir, 2005) 为年轻的聋人 L1 瑞士德语手语 (DSGS) 用户的新句子重复测试 (SRT) 寻求有效性证据。已针对口语和手语的各种目的开发了 SRT，以评估儿童的语言发展。为了满足评估聋人 L1 DSGS 用户在学校环境中的语法发展的测试需求，我们开发了 SRT。该测试针对 6-17 岁的年轻学习者，我们对 46 名年龄在 6.92-17.33 (M = 11.17) 岁的聋哑学生进行了测试。除了年轻学习者的数据之外，我们还收集了聋哑成年人（N = 14）和儿童子样本（n = 19）的数据，他们也接受了 DSGS 叙事理解测试，作为衡量标准。我们用多方面的 Rasch 模型分析了数据，回归分析和协方差分析。结果显示了评分、标准和上下文有效性的证据，表明 SRT 适合预期目的，并将告知测试的修订版本，以便将来用作评估聋儿童手语发展的工具。
