近年来，认知变化的研究取得了重大进展，从传统的群体水平参数方法发展到新的技术，如可靠变化指数（RCI）和基于标准回归（SRB）的变化评分。在心肺转流术后认知变化的非常有趣的研究中，基思等人（2002）选择了更传统的组水平变化分析（混合因素方差分析）。他们列举了个人层面分析技术（如RCI）的几个局限性。在这篇评论中，作者试图解决这些具体的问题，以及一些由认知变化的分析提出的一般性困难。讨论了RCI和SRB方法的优缺点。
There have been significant advances in the study of cognitive change in recent years, evolving from traditional group-level parametric methods to new techniques such as the reliable change index (RCI) and the standardized regression-based (SRB) change score. In the very interesting study of cognitive change following cardiopulmonary bypass, Keith et al. (2002) opted for a more traditional group-level analysis of change (the mixed factor analysis of variance). They cited several limitations of the individual-level analytic techniques such as the RCI. In this commentary, the author attempts to address these specific concerns as well as some of the mote general difficulties presented by the analysis of cognitive change. Advantages and disadvantages of the RCI and SRB methods are discussed.
