Research concerned with children and young people who have neurodevelopmental disabilities (ND) in relation to early language acquisition usually involves comparisons with matched group(s) of typically developing individuals. In these studies, several important and complex issues need to be addressed. Three major issues are related to: (1) the choice of a variables on which to carry out group matching; (2) recruiting children into the study; and (3) the statistical analysis of the data. To assist future research on this topic, we discuss each of these three issues and provide recommendations about what we believe to be the best course of action. To provide a comprehensive review of the methodological issues, we draw on research beyond the topic of early language acquisition. Our overall aim is to contribute to research that considers questions about delay or differences in development patterns of development and about identifying potentially causal variables.
关于患有神经发育障碍（ND）的儿童和青少年早期语言习得的研究通常涉及与发育正常个体的匹配组进行比较。在这些研究中，有几个重要且复杂的问题需要解决。三个主要问题涉及：（1）进行组匹配所依据的变量选择；（2）招募儿童参与研究；以及（3）数据的统计分析。为了协助未来关于该主题的研究，我们讨论这三个问题中的每一个，并就我们认为的最佳行动方案提供建议。为了全面回顾方法学问题，我们借鉴了早期语言习得主题之外的研究。我们的总体目标是为考虑发育延迟或发育模式差异问题以及识别潜在因果变量的研究做出贡献。
