Abstract
Normative data were presented that defined the upper and lower standards for deciding if cognitive abilities show reliable change over 2 or more testing occasions when retesting occurs at 1- to 2-year intervals. The Mayo Cognitive Factor Scores (MCFS; G. E. Smith et al., 1994) were analyzed because they permit the quantitation of overall functioning in 5 clinically important cognitive domains: established verbal knowledge, nonverbal reasoning, attention and concentration, new learning, and delayed memory. To the authors' knowledge, this is the first report of both group-level and individual-level data analyses derived from a respectably sized sample of normal persons who have been tested 3 or more times at clinically common test-retest intervals.
