Delaying Gratification Inventory (DGI-35 and DGI-10)
The DGI measures individual differences in gratification delay, or the tendency to pursue immediate versus later, greater rewards. It can be administered as a long form (DGI-35) or short form (DGI-10). The measure's theoretical factor structure was derived from six decades of prior literature and covers delay behavior across five domains: food, physical pleasures, social interactions, money, and achievement. Prior measures of delay of gratification, as well as related constructs such as delay discounting, tend to require in-depth experimental procedures and/or use surveys with limitations related to reliability, validity, scope, or item wording. The DGI has been used with >10,000 participants worldwide and translated into many languages.
