INTRODUCTION: The objective of this study was to perform the transcultural adaptation of the Delaying Gratification Inventory (DGI) and evaluate its psychometric properties related to validity and reliability. METHODS: The inventory was translated by two bilingual researchers, followed by a back-translation and analysis of item adequacy and content by expert judges. We assessed its psychometric properties in a sample of 562 Brazilian adults, which responded DGI in the internet. We assessed reliability by internal consistency and test-retest stability, and validity by correlations with other measures and group comparisons. RESULTS: We found evidences of validity and reliability for the Brazilian context. We also established preliminary values for interpretation of the questionnaire in this context. CONCLUSION: the Brazilian version of the DGI is suitable for use in this context, allowing clinicians and researchers to use this brief instrument to evaluate the ability to delay gratification.
