摘要目的分析3~12个月儿童语言习得构筑发音标志的验证结果。方法以发音视角下的语言习得机制为基础，结合语言障碍的临床经验，建立语言习得体征。这些手势由六名专家组成的样本提交给清晰度和相关性的判断，这些专家是具有心理语言学和语言诊所知识的语言学医生。在可靠性验证中，两名评委/评价员使用评价员间的方法，在占母婴双亲样本总数20%的视频中帮助实施了这些工具。对总样本采用内部一致性方法，包括94个母婴二元组至第一阶段(3-6个月)的含量和61个母婴二元组至第二阶段(7-12个月)的含量。收集的数据是通过分析母婴相互作用的基础上拍摄的二元体，并应用参数，以验证根据孩子的年龄。数据被组织在电子表格中，然后转换为计算机应用程序进行统计分析。结果清晰度/相关性的判断表明，工具未作任何修改。信度检验显示评委之间几乎完全一致(0.8≤Kappa≥1.0)；只有阶段2的基本一致(0.6≤Kappa≥0.79)。阶段1的内部一致性α=0.84，阶段2的内部一致性α=0.74。这证明了仪器的可靠性。结论两个年龄段的语言习得发音符号量表的内容效度均符合要求，说明语言习得发音符号的内容具有相关性。
ABSTRACT Purpose To analyze the results of the validation of building enunciative signs of language acquisition for children aged 3 to 12 months. Methods The signs were built based on mechanisms of language acquisition in an enunciative perspective and on clinical experience with language disorders. The signs were submitted to judgment of clarity and relevance by a sample of six experts, doctors in linguistic in with knowledge of psycholinguistics and language clinic. In the validation of reliability, two judges/evaluators helped to implement the instruments in videos of 20% of the total sample of mother-infant dyads using the inter-evaluator method. The method known as internal consistency was applied to the total sample, which consisted of 94 mother-infant dyads to the contents of the Phase 1 (3-6 months) and 61 mother-infant dyads to the contents of Phase 2 (7 to 12 months). The data were collected through the analysis of mother-infant interaction based on filming of dyads and application of the parameters to be validated according to the child's age. Data were organized in a spreadsheet and then converted to computer applications for statistical analysis. Results The judgments of clarity/relevance indicated no modifications to be made in the instruments. The reliability test showed an almost perfect agreement between judges (0.8 ≤ Kappa ≥ 1.0); only the item 2 of Phase 1 showed substantial agreement (0.6 ≤ Kappa ≥ 0.79). The internal consistency for Phase 1 had alpha = 0.84, and Phase 2, alpha = 0.74. This demonstrates the reliability of the instruments. Conclusion The results suggest adequacy as to content validity of the instruments created for both age groups, demonstrating the relevance of the content of enunciative signs of language acquisition.
