Computer programs designed to collect clinical information from patients have been extant for a number of years. Recent efforts, however, have focused on the development of computerized forms of psychotherapy. Cognitive therapy has been modified for use in such computerized psychotherapy programs, primarily because of its structured format, logical approach to therapy, and its empirically demonstrated efficacy. We present a case study in which a computerized form of cognitive psychotherapy was used to treat a depressed, hospitalized patient. The interactions between the patient, the computer, and the personnel involved in assisting the patient with the computerized psychotherapy suggest that the interpersonal context in which the computerized therapy takes place is essential to the treatment process. Moreover, the case suggests that the interpersonal processes which occur during the delivery of CT in any form are essential to its effective delivery.
