Discounting of Various Types of Rewards by Women with and without Binge Eating Disorder: Evidence for General Rather than Specific Differences

The present study compared the extent to which obese women with binge eating disorder (BED), obese women without BED, and controls discounted delayed and probabilistic money and directly consumable rewards: food, massage time, and preferred sedentary activity. Of special interest was whether the BED group differed from the other groups in terms of their discounting of all three types of directly consumable rewards or only in their discounting of food. Overall, the BED group tended to discount both delayed and probabilistic rewards of all types more steeply than the obese and control groups. Thus, rather than finding differences specific to particular types of rewards, we find that women with BED are generally more impatient when choices involve delayed rewards and more risk averse when they involve probabilistic rewards. These results suggest a temperamental difference associated with BED that cannot be accounted for by the concomitant obesity. (Contains 1 table, 4 figures and 2 footnotes.)
