Explanation:

Solution-focused therapy is based on the humanistic approach that focuses on the responsibilities, self- love, and growth. It aims at finding a solution to the problem rather than fixing it. Solution-focused therapy focuses on a person's present problems and future circumstances rather than past experiences. In this therapy, the therapists focus more on the person rather than the problems, and to look for resources rather than failure. They help people to identify their problems and find a way out of those problems.
