November 5, 2015 - Validation of Cogstate for Self-Administered Cognitive Testing – CTAD Announcement

Study Conclusions – CTAD Announcement 2015

The findings of this pilot study suggest that reliable cognitive data can be obtained from iPad assessments in the home environment without the assistance of a trained administrator. The at-home and in-clinic assessments were correlated with standard neuropsychological tests at a similar magnitude, but the at-home assessments did not reach statistical significance due to small sample size. With everyone receiving initial in-clinic training, a very high percentage of older individuals completed the majority of at-home assessments without any assistance. The major limitation was selecting the appropriate test version each day, not the ability to do the tests. These findings suggest that with selected iPad modifications and automation of test version selection, the feasibility of doing at-home assessments shows promise for inclusion into clinical trial designs.
