I certainly think “multi-day” at a minimum should be two days, with the first day discussing theory—with, as was suggested by Sharalyn, case studies. We have found this to be very effective in the work we do in the Caribbean, for example.
On the second day we must have, in addition to case studies, persons from the affected communities there to interact with the IRB members who are being trained. It won't be a comprehensive exposure, but it at least gives them some better sensitivity.
That's what I recommend. There must be case studies and there must be interaction with the persons who are affected.
I don't know whether Sharalyn wants to add.
