People with anorexia nervosa or bulimia nervosa report anomalous self-experiences (ASEs) at levels comparable to those seen in schizophrenia. In a study of 90 individuals with anorexia, 41 with bulimia, and 92 general-population controls, ASEs were strongly correlated with feeling extraneous from one's own body, body uneasiness, and eating-disorder symptoms. Statistical modeling showed that ASEs influence eating-disorder symptoms indirectly, through disturbances in embodiment, identity, and body image. The findings suggest that anomalous interoceptive processes may initiate a maladaptive cascade that impairs embodiment and selfhood in feeding and eating disorders, and that assessing ASEs could help identify an early shared vulnerability across severe disorders involving altered embodiment.
