Correct Response: C. Anorexia and bulimia nervosa are mental health disorders in which individuals tend to develop and follow ritualistic behaviors in order to control body weight. These eating disorders may be characterized by distorted body image; preoccupation with weight, food, and calories; adherence to strictly controlled dietary and exercise regimens; and binge eating and purging. Some professionals believe that a perceived lack of control in other aspects of life may contribute to the need to exert control over something, such as eating, exercise, and weight control. Bipolar (manic depressive) disorder (A) and schizophrenia (B) are mental health disorders caused in part by an imbalance of brain chemicals. Exercising excessive control over one's body is not significant in the development of these disorders. Asperger's syndrome (D) is a developmental disorder in which the ability to socialize is especially compromised. A need to exert control over one's body is not a contributing factor to the development of Asperger's.
