The purpose of this study was to examine the degree to which
delay discounting, probability discounting, and/or response inhibition
are uniquely related to obesity in a community sample of
young adults. Based on the extant literature, we hypothesized that
all three measures would be significantly related to BMI and obese
participants would exhibit more impulsive patterns of decisionmaking
on all three measures, but that delay discounting would
account for the most variance when all three measures were
examined simultaneously.
