Test-retest stability of the Continuous Visual Memory Test in elderly persons.
Ninety-two normal elderly persons were administered the Continuous Visual Memory Test (CVMT) on two occasions an average of 1.1 years apart. Means for age and education were 69.02 years (SD = 5.79) and 14.80 years (SD = 2.64), respectively. Stability coefficients were.49 on the Total score,.44 on d-prime, and.48 on Delayed Recognition. D-Prime and Delayed Recognition scores demonstrated significant change on retest. To assist clinicians in the process of detecting meaningful change on retest, standard error of difference values and 90% cut-off scores were provided.
