概括性理论（GT）为评估研究提供了更多的效用，因为它能够同时检查多个方差来源，为相对和绝对决策提供信息，并确定结果的一致性和概括性。尽管有这些优势，教育和心理学领域的评估研究人员在采用和利用GT方法方面进展缓慢。这种未充分利用可能是由于对GT的概念基础、设计和实施概括性研究所涉及的实际步骤或这两个问题的某种组合的不完全理解。因此，本文的目标是双重的：(a)为读者提供与GT使用相关的概念背景和术语，以及(b)促进理解在设计、实施和解释概括性和可靠性研究时需要考虑的一系列问题。考虑到这种分析方法与应用评估背景的相关性，有必要确保教育和心理学研究人员既可以访问GT，也可以理解GT。提出了重要的方法和分析考虑因素，并描述了应用的含义。(C) 2013年学校心理研究学会。Elsevier Ltd.出版。版权所有。
Generalizability Theory (GT) offers increased utility for assessment research given the ability to concurrently examine multiple sources of variance, inform both relative and absolute decision making, and determine both the consistency and generalizability of results. Despite these strengths, assessment researchers within the fields of education and psychology have been slow to adopt and utilize a GT approach. This underutilization may be due to an incomplete understanding of the conceptual underpinnings of GT, the actual steps involved in designing and implementing generalizability studies, or some combination of both issues. The goal of the current article is therefore two-fold: (a) to provide readers with the conceptual background and terminology related to the use of GT and (b) to facilitate understanding of the range of issues that need to be considered in the design, implementation, and interpretation of generalizability and dependability studies. Given the relevance of this analytic approach to applied assessment contexts, there exists a need to ensure that GT is both accessible to, and understood by, researchers in education and psychology. Important methodological and analytical considerations are presented and implications for applied use are described. (C) 2013 Society for the Study of School Psychology. Published by Elsevier Ltd.
