E-Therapies for Anorexia Nervosa, Bulimia Nervosa and Binge Eating Disorder Eating disorders can often be treated with psychotherapy, but mostly due to a lack of trained clinicians, the majority of the persons concerned do not receive any treatment. In recent years, internet-based psychotherapy (e-therapy) was proposed and tested in several pilot projects as a novel possibility to offer a larger number of places on a treatment program with a constant number of available clinicians. Recent results are promising, but before an implementation into standard care can take place, more detailed knowledge must be provided as to which patients may be recommended this type of therapy as an equivalent alternative to traditional face-to-face therapy.
