According to Carl Rogers, the role of the therapist in person-centered psychotherapy is to accept the client unconditionally so that the client's own desire for mental health and positive growth will flourish A express warmth and empathy and suppress negative feelings that arise in the relationship with the client B use a didactic approach to teach the client to correct maladaptive behavior C establish behavior-change programs to alter the problematic behavior that is often learned in early childhood D define ideal characteristics of mental health for the client and to encourage the client to incorporate these elements in his or her personality
