"Approximately two-thirds of the subjects with anorexia nervosa reported perfectionism and rigidity in childhood. This prevalence is consistent with that reported by Rastam (22) for premorbid obsessive-compulsive (or anankastic) personality disorder in anorexia nervosa. We are not aware of any similar studies conducted for patients with bulimia nervosa. However, previous findings that perfectionism, obsessionality, excessive concern about mistakes, and doubt about actions persist after recovery from both disorders suggest that they represent persistent traits (10, 13, 16)."
