127 of those for whom the surgical intervention might present a psychologi- cal risk. In addition, these studies do not indicate that the morbidly obese have any higher degree of psychopathology than the general population. This is confirmed by clinicians who evaluate these clients for gastric bypass. They agree on the lack of psychopathology in the population. Type distributions for this population revealed that 40% were dominant feeling types and 34% were dominant sensing types, 15% dominant intuition, 9% dominant thinking, and no preference was overrepresented or underrepresented compared to the base population. The base popula- tion in this case was the total number in all three groups (n=55). In the gastric bypass group there were some interesting findings that have not been previously reported. Feeling types had a more affective response to pain than thinking types. This is probably a result of the fact that there were significantly more women in that group. Apart from gender, this particular operative procedure held special significance for those subjects who have turned to such a radical treatment for their problems. They were people who have tried many weight reduction programs over many years without success. Their overall physical health has been affected by this problem, and they have had to suffer in a society that puts great value on physical attractive- ness. The affective scale measures fear and tension, using value-laden words such as "tiring, fearful, punishing" and "wretched."
