| Research Abstract |
The results of the present study, the aim of which was to prepare for developing a new treatment system for eating disorders, were as follows. To investigate hyperactivity, one of the important clinical symptoms, patients and healthy controls were asked to wear accelerometers to assess objective physical activity. We found that the phase of the diurnal rhythm of physical activity significantly moved more forward in anorexia nervosa (AN) restricting type than in healthy controls while consumption energy by physical activity was smaller in AN patients than in controls. In addition, we developed computerized ecological momentary assessment (EMA) system for assessing and recording symptoms, behavior, and food intake, which will be able to apply to intervention in natural settings.
