From a viewpoint of behavioral science, there are mainly three problems in relation to eating behavior, as summarized in the following.1) The latest increase of processed foodstuffs is gradually changing our eating habits and influencing our health or the onset and process of our diseases.2) Eating behavior is playing an important role to reduce a stress, consequently an abnormal eating behavior is easily learned.3) The development of the theory about eating behaviors and it s treatment techniques is strongly expected.In this paper, we proposed the mechanism of development and treatment techiniques about anorexia nervosa from the viewpoint of behavioral science.Furthermore, we reported a case study using an operant conditioning technique and discussed a few problems which were observed in a course of treatment.1. Mechanism of development of anorexia nervosa from the behaviorak point of view.Anorexia nervosa can be understood as a mainfestation of abnormal eating behavior which has been continuously reinforced, according to operant principles, by reward of attention and anxiety reduction because it serves to avoid a stressful-life situation by means of the disease state.2. Behavioral therapy of anorexia nervosa-especially about operant conditioning technizues-1) Extinction of reinforcing factors.2) Positive procedures for reshaping a desirable eating behavior by operant management.3) Procedures for reshaping a desirable adaptive behavior by self-control techniques or soial skill-training.4) Behavioral counselling.3. Case report The patient was a 31-year old female and was out of work. She had a 16 years' history of the disease and it was very severe.Her symptoms almost recovered after two years' treatment centering upon operant conditioning. She is still in good condition 18 months after her discharge.4. Results Out of 110 cases treated with the above-menioned behavioral approach, our therapy was not completed because of their escape from the hospital in nine cases and because of suicide in 1 case. The remaining 100 patients were received behavioral therapy for periods between a month ad 24 months and it was successfully completed.Twenty three cases had a relapse of the disease and 13 of them were readmitted.Four out of 23 relapsed cases recovered spontaneously from a disease state.
