There are many scales for screening or assessing the impact of a disease. These scales are generally used to diagnose or assess the severity of a disease and are carried out at the request of a physician by the patient. Conversational agents could make it possible to administer these questionnaires remotely, analyse them and use the results on a large scale, without prior medical intervention.
