Have there been any concurrent validity studies comparing CNS Vital Signs to conventional tests?
We have completed two studies of concurrent validity with CNS Vital Signs, and are conducting two more at this time. The first was a comparison of CNSVS to the NES2 computerized battery, RAVLT, and verbal fluency test. A second study compared CNSVS to a battery of traditional neuropsychological tests: RAVLT, Finger Tapping Test, Digit Symbol-Coding from the Wechsler IQ scales, and a version of the conventional Stroop test.
