Assessments will be performed before rTMS and after the last rTMS session (immediately after, at 15 days and three months). The principal criteria for judgement is a body image satisfaction scale (Boby Shape Questionnaire, BSQ-34). The secondary criteria for judgement are eating behaviour scales (Eating Attitude Test, EAT-40; Bulimia test, BULIT and Eating Disorders Inventory, EDI-2), the Hamilton depression rating scale and Hamilton anxiety rating scale, a quality of life scale (Short-Form Health Survey, SF-36), a body composition analysis using a Dual-energy X-ray absorptiometry and the alpha-MSH autoantibodies levels (biomarker for eating disorders recently described).
