The aim of this research is to adapt the Delay of Gratification Inventory to a Turkish adult sample. The data for the study was obtained from adults over the age of 18 between April and May 2021. The "Personal Information Form," the "Delay of Gratification Inventory," the "Psychological Well-Being Scale," and the "Barratt Impulsivity Scale Short Form" were used to collect research data. In addition to construct validity and criterion-related validity in the validity assessment of the inventor, in the reliability evaluation, Cronbach’s alpha internal consistency, test-retest, and lower-upper 27% group difference values were examined. In exploratory factor analysis, the measurement tool consists of five sub-dimensions, and these sub-dimensions explain 52% of the variance. The conclusion of the CFA show that the five sub-dimension structure obtained has a good fit (χ2 = 352.97 N = 265, sd = 184, p = 0.00; χ2 / df = 1.92, RMSEA = .059, CFI = .90, IFI = .90, GFI = .89 and AGFI = .86). In another validity study, it was found that delaying gratification was positively related to psychological well-being and negatively related to impulsivity. Within the framework of reliability, the Cronbach’s alpha internal consistency coefficient of the whole inventory was found to be .78. The test-retest coefficient for the whole inventory was found to be .84.
