Michael, As far as I know, there are only two forms of the Reitan test. Furthermore, they are really bad--the switch task is a lot harder to solve, even if you were not switching. I would recommend against using any of the reitan foms unless you have a really good reason to do so (i.e., validation/comparison).
The PEBL version solves this by giving everyone the same problem in both conditions, but reflected so that you are less likely to have learning effects. Now, if you are just giving this twice with a 9-month separation, you could reuse the same five tests. If you were doing it weekly, it would be better to generate new tests each time. To use the same tests every time PEBL is run, the easiest way to do so is to uncomment the SeedRNG(304) line at the beginning of the test. It should give everyone the same order of tests every time it is run. You could pick another value other than 304 if some of the tests are less than ideal, or to pick another consistent set. The other thing you could do is take generated configurations (either by hand or via PEBL) and save them, in the same way the reitan test values are saved in the ReitanPoints() function. This would insure a permanent record of the tests you used. It would take a little more effort to do, but you would have more control over the problems.
