Generalizability and decision studies provide a mathematical framework for quantifying the stability of a given number of measurements. This approach is especially relevant to the task of obtaining a representative measure of communicative behavior in young children and supports an alternative to the debate regarding which type of assessment yields the most representative scores. The current paper provides a report of a generalizability and decision study on 63 toddlers with developmental delay who were treated for 6 months using an intervention that targeted communication and vocabulary goals. Two variables - rate of intentional communication acts and rate of different words - were measured across three assessment contexts at four communication sampling periods. Results verified that measurement stability increased with time and development for both variables, regardless of the type of assessment procedure used.
概化性与决策研究提供了一个数学框架，用于量化给定数量测量的稳定性。这种方法对于获取幼儿沟通行为代表性测量的任务尤为相关，并支持了关于哪种评估类型能产生最具代表性分数的争论的另一种观点。本文报告了一项针对63名发育迟缓幼儿的概化性与决策研究，这些幼儿接受了为期6个月的以沟通和词汇目标为导向的干预治疗。在四个沟通抽样期的三种评估情境下，对两个变量——有意沟通行为的速率和不同单词的速率——进行了测量。结果证实，无论使用何种评估程序类型，这两个变量的测量稳定性都随时间和发育而增加。
