Consumer decision-making is part of the purchase process. Therefore, as a relevant element for the evaluation of the purchase process, it is essential to have valid, reliable and culturally relevant measurements. For that reason, in this study the development and validation of the Purchases Decision-Making Inventory (PDMI) are presented. The general sample consisted of 518 Mexican participants, which were randomly divided into two groups, 300 for exploratory analysis, and 218 for confirmatory analysis. The results show that PDMI evaluated from its general components of emotional and reasoned decisions in purchases, present high internal consistency. The confirmatory factor analysis shows a good fit to dimensions extracted from the exploratory analyses. In terms of convergent, divergent, and discriminant validity, relations according to the nomological network were found, and the factors showed independency. Finally, from the confirmed structures of the inventory, spending per week was modelled, finding that emotional decisions turned out to be a positive significant predictor. PDMI is an evaluation tool with cultural relevance and appropriate psychometric indexes that can be used to integrate into consumer behavior models.
