A 33-year-old man with alcohol use disorder, currently two weeks sober, presents feeling hopeless about maintaining recovery. He states, 'I've tried everything and nothing works. I always relapse.' His PMHNP, using Solution-Focused Brief Therapy (SFBT), responds by asking: 'Suppose tonight, while you are asleep, a miracle happens and the problem that brought you here is solved. When you wake up tomorrow, what would be the first small sign that tells you something is different?' The patient pauses, then says, 'I guess I would wake up and actually want to get out of bed. I'd make coffee and call my sponsor.' Which SFBT technique has the therapist employed, and what is its primary therapeutic function?
