The studies I have seen suggest that adding to a losing trade doesn't help....but rolling for duration or more credit does.

However you can hedge a losing put by selling calls as well. Just select the deltas you want to take off and sell those(this will also reduce the buying power reduction of the naked puts)....then if the position continues to move against your puts you can roll the calls down to maintain the delta hedge. Don't go inverted on the strikes until you learn what that means....and don't roll for a debit....unless it is very small.

Or you can let the puts get assigned if you don't mind owning the underlying at that price and then sell calls against that. Synthetically speaking ...selling a put is basically the same as doing a covered call.
