The concept of a contactful, interpersonal therapeutic relationship is the central premise in the practice of integrative psychotherapy. Inquiry, attunement, and involvement constitute the methods of a contact-oriented, relationship-based psychotherapy. Eight relational needs are defined, and reciprocal psychotherapeutic responses are described. The theoretical basis for an integrative psychotherapy includes the concepts of ego states, transference, the script system, contact and interruptions to contact, and the significance of interpersonal relationships.
