New technologies have been greatly developed during last years and it has also being widen altogether the fields where they can be useful, like in the Eating Disorders (ED). The Eating Disorders Unit of South London and Maudsley Hospital, always interested in the development of new interventions, has performed pilot studies focused in the use of a computerized program, based on cognitive-behavioral techniques, for the treatment of the ED. Also a preliminary research about relapse prevention in bulimic patients by sending messages through cellular phones has been carried out. These studies, together with many other ones, are a clear example of the interest that the use of these technologies is arising in the therapeutic environment; representing also a first step in the study of their therapeutic effectiveness.
