Hi all,
This may be kind of a silly question, but my PhD advisors are not able to provide solid guidance on this question for whatever reason (even though one is a neuropsychologist).
We are piloting and attempting to demonstrate the reliability and validity of two new computerized cognitive tests we have developed. In the next planned study, we aim to test healthy adults, as well as (at least) people with PD and AD. We are doing testing remotely D/T COVID and will likely continue doing so because of the success we had in our initial pilot (we were able to test 130+ people in a few months).
My question that can't be answered by my mentor is the following: to demonstrate content validity, we are aiming to compare our computerized cognitive tests against: Logical Memory I and II from the WMS-IV, Digit Span from WAIS-IV, and FAS/CAT (COWAT, which I do not believe is copyrighted). We are debating using the TICS as a screener, but could be open to do the MMSE as well or the MOCA or other options.
So, my question is: as a student with a very limited research budget, do I need to purchase the whole WMS-IV kit and testing materials to ethnically administer that sub-test in a research context? Same with the WAIS-IV for just using digit span? And the TICS/MMSE/MOCA? That's gonna add up really fast. For reference, I can easily find all of these tests in the current practicum I work for, which is at the same broad institution as my research/PhD program. Our PhD 2nd year prac program also has access to all of the materials, but our lab technically does not I believe.
Thanks in advance for any advice. I will eventually reach out to test developers, but I wanted to ask here first so I at least sound somewhat informed when reaching out to them.
