Do you mean what Kazdin calls the "positive opposite"? I wrote a review here:

But the idea of the positive opposite really is to reward specific oppotite behavior. Not to divert from a problematic activity by distracting with other behaviors.

I long believed distraction to avoid solving the original problem and it may actually reward the problematic behavior. So I'm still not convinced distraction works.
