I don't know how much of a unique problem this is with Prius, but I doubt oil change interval has much to do with it. I've checked my oil condition with yearly changes and it was still well within spec.
The unique thing about the Prius is that it's designed to run the engine at high load continuously, which puts more strain on everything. If excessive wear is a problem with the Prius, I would suspect the cause is high loads and thin oil (0w20).
