An in-depth study of the comparison of Client-Centered and Behaviorist approaches in counseling has important significance in developing effective counseling practices. By understanding in depth these two approaches, counselors can gain a better understanding of the principles, and goals used in each approach. It is important to examine the differences between the Client-Centered approach that emphasizes empathy, understanding, and acceptance of clients as unique individuals, and the Behaviorist approach that focuses on behavioral change through measurement and reinforcement techniques. The objectives of this study are (1) to determine the concept of the client-centered approach. (2) to determine the concept of the behaviorist approach. (3) to determine the comparison of the client-centered and behaviorist approaches.
