| Delay discounting (DD), a behavioral measure of impulsivity, is a decrease in the current subjective value of a reward as delay to its receipt increases. Research demonstrates that acceptance-based training (ABT) can alter patterns of discounting for monetary rewards, but this had not been tested with food DD. The purpose of the present study was to determine the extent to which an ABT for impulsive food choice would alter DD for food. Twenty-four participants were randomly assigned to ABT or DVD control. Each participant completed baseline, post-test, and a one-week follow-up food and money DD tasks. There was a significant difference between post-test and the 1-week follow-up for food DD, but no differences between ABT and DVD groups. No significant differences were observed for money DD. These results do not replicate previous research that shows ABT decreases delay discounting.
