Interesting question.I don't see any reason why Harvey's Strong Mind would not operate during set up, so at least one sanity saved.
Investigators who draw an extra card of a certain type (Monteray, Pete, etc.) Only draw one extra card, even though they have two starting items of that type. This implies that receiving items is a single event, so in my opinion, Harvey still loses one.
As for any other time Harvey got two items, it would depend on wether he got them from two different events; any single event which gave two or more items would cause sanity loss after the first.
I think.
