Reality therapy is a cognitive-behavioral approach developed by William Glasser that focuses on taking responsibility for one's actions and meeting needs in constructive ways. The counselor's role is to keep clients focused on the present and developing specific plans to improve behavior. The ultimate goal is for clients to feel better by gaining effective control over their lives and meeting needs without depriving others. Reality therapy uses techniques like confrontation, planning, and evaluating behaviors to help clients develop a success identity based on responsible fulfillment of needs.
