Determining Reliable Cognitive Change after Epilepsy Surgery: Development of Reliable Change Indices and Standardized Regression‐based Change Norms for the WMS‐III and WAIS‐III

Abstract

We calculated both RCI and SRB change score indices for the recently revised Wechsler instruments. These formulas help control for test-retest methodologic artifacts and provide a standardized method with which to examine both individual and group level cognitive change after epilepsy surgery.
