RC = reliable change; Results are only reported for cognitive measures with test-retest reliabilities above .50. When interpreting an individual patient’s pattern of scores, test-retest differences falling at or below the lower limit of the RC interval or at or above the upper limit of the RC interval would be indicative of clinically meaningful change.
