method to enforce the patient to eat and gain weight. They do this by presenting rewards every time he/she successful eats. Kadzin (1989) described at study conducted by Pertschuk, Edwards, and Pomerleau in severely They 1978 invol ng anorexic patients. administered the program by giving patients the opportunity to earn rewards for every one-half pound they gained. About two weeks into the program the patients gained an average of 9.3 pounds. Patients who do not agree to this program continued to lose weight. Patients who did gain weight had a goal and were able to reach that goal by earning incentives. This pushed the patients even more to overcome their sickness. The results of this study correlate with the theory on behavior modification. The researchers were able to control the behaviors emitted by the patients through rewarding them every time they performed the desired behavior. Like in the previous studies, these patients were able to develop a relationship with gaining weight and obtaining a reward. The more they ate, the more reward they received making the behavior of eating more desirable for the patient.
