A recent study collected information from surveys conducted among the members of the Association for Psychological Science and the American Psychological Association. The study identified the top 100 eminent psychologists of the 20^th century. Not surprisingly, Skinner, Piaget, and Freud are the top three. What may be of interest is that Carl Rogers is ranked number 6.

Among the reasons cited is Rogers’ groundbreaking work in the development of humanistic or client centered therapy. What made it groundbreaking was his insistence that the model be subject to scientific inquiry and clinical trial. One result of his work was a psychological theory. In that work Rogers advanced a complex set of 19 propositions describing his theory. In this article we will make an effort to provide a brief overview of it.

To provide theoretical legitimacy to his clinical work, Rogers wrote 16 books and even more articles explaining how these 19 propositions worked on understanding the human personality. Among the most significant key points of Rogers’ approach is its redefining of the therapeutic relationship. Traditionally that relationship was defined by the theories of Freud and others where the therapist role was that of a leader and the patient as the follower.

Rogers argued that for the therapist/patient relationship to be effective, it must include an intentional relationship built on mutual trust and respect. In the later years of his work Rogers expanded his model to apply to other applications including a theory of personality, interpersonal relations, education, nursing, cross-cultural relations and other “helping” professions and situations.
