One other thing--If the VCI and PRI were extremely different from one another, the GAI may not be valid either. Perhaps someone with more experience can chime in here.
Well, this is another problem, apparently there is one standard deviation between his VCI and his PRI . But there are four standard deviations between the VCI and the PSI. So while both are technically invalid, in my mind the FsIQ based on 4 SDs is more invalid than the GAI which would encompass 1SD. Neuropsych wants to report the FSIQ but does not want to report or calculate the GAI. It really makes no sense to me. Ayi yi yi!
