Multifactorial models of dyslexia have expanded how we consider heterogeneity within the population of children with dyslexia. These models are predicated on the idea that cognitive/linguistic risk factors are not deterministic but instead probabilistic, with the likelihood of difficulties involving an interaction between risk and protective factors that include both exogenous and endogenous influences. In this commentary a multifactorial model perspective is applied to examine, based on the six papers that make up the special series, the potential utility of such models to clarify issues of etiology, identification, and instruction of children with dyslexia. This approach seems to suggest that multifactorial models of dyslexia have potential to significantly expand our understanding of etiology with less immediate promise for identification and instruction.

阅读障碍的多因素模型扩展了我们如何考虑阅读障碍儿童人群中的异质性。这些模型基于以下思想：认知/语言风险因素不是确定性的而是概率性的，困难的可能性涉及风险与包括外源性和内源性影响的保护性因素之间的相互作用。在这篇评论中，基于构成特殊系列的六篇论文，采用了多因素模型的视角来研究这种模型在阐明儿童阅读障碍的病因，识别和指导方面的潜在用途。
