Thanks for all your replies. Digesting all your comments I suspect it's best to support with support at the required level immediately. Otherwise surely the 'psycher' is going to barrage in their fit or escape suit at some uncomfortable level and further bidding could get muddled. That leaves 'pass' as showing a very minimum opening and 'double' to show some sort of NT hand without a stop in their suit.

This auction occurred recently at my club. 1♦-1♥-X-1♠ The double was negative and promised 4♠. Opener had 4♠. We missed our fit as we had no agreed system in this area. In fact we missed our spade game as the 1♠ overcaller had psyched on QXX. My question is what do you think is the best rebid that opener can make when holding 4 card spade support ? Thanks in advance.
