The consistency of parental reports of expressive vocabulary and word combinations with observed expressive language among 21- to 27-month-old children exposed to English and Spanish on a regular basis was the focus of this investigation. Parental reports were obtained using the Spanish-English Vocabulary Checklist (Patterson, 1998), an adaptation of the Language Development Survey (Rescorla, 1989). The number of different words parents reported was correlated (r = .66) with the number of different words the children used during a 30-min videotaped interaction with the reporting parent. Parental reports of whether the child was combining words and estimates of proportion of the child's use of Spanish and English also were consistent with the children's language use during the 30-min language samples.
本调查的重点是，定期接触英语和西班牙语的21至27个月大儿童的父母关于表达性词汇和单词组合的报告与观察到的表达性语言之间的一致性。父母报告是使用《西班牙语-英语词汇清单》（帕特森，1998年）获得的，该清单是对《语言发展调查》（雷斯考拉，1989年）的改编。父母报告的不同单词数量与孩子在与报告家长进行30分钟录像互动期间使用的不同单词数量相关（r = 0.66）。父母关于孩子是否正在组合单词的报告以及对孩子使用西班牙语和英语比例的估计也与30分钟语言样本期间孩子的语言使用情况一致。
