Self-administered online test of memory functions

Abstract

Online cognitive tests have gained popularity in recent years, but their utility needs evaluation. We reviewed the available information on the reliability and validity measures of tests that were designed to be performed online without supervision. We then compared a newly developed web-based and self-administered memory test to traditional neuropsychological tests. We also studied if familiarity with computers affects the willingness to take the test or the test performance. Five hundred thirty-one healthy individuals, who have a history of a perinatal risk and who have been followed up since birth for the potential long-term consequences, participated in a traditional comprehensive neuropsychological assessment at the age of 40. Of them, 234 also completed an online memory test developed for follow-up. The online assessment and traditional neuropsychological tests correlated moderately (total r = .50, p < .001; subtests r = .21−.45). The mean sum scores did not differ between presentation methods (online or traditional) and there was no interaction between presentation method and sex or education. The experience in using computers did not affect the performance, but subjects who used computers often were more likely to take part in the voluntary online test. Our self-administered online test is promising for monitoring memory performance in the follow-up of subjects who have no major cognitive impairments.
