The objective of the study is to analyze the reliability and validity evidence based on the internal structure of the InCharge Finance Distress / Financial Wellbeing (IFDFW). It was administered to 545 citizens from the three regions of Peru (coast, the Andes and the rainforest). There were 296 women and 243 men, with an average age of 33.45 years (SD= 9.65). Confirmatory factor analysis provided adequate support for the 8-item one-dimensional model with the presence of correlated errors (CMIN= 58.635, DF = 17.00; CMIN/DF =3.449; CFI = 0.979; RMSEA= 0.067; SRMR= 0.032; and PClose = 0.061), also showed a good convergent internal validity based on the value of AVE = 0.554. Regarding reliability, a Cronbach's alpha = 0.881 and a CR= 0.91 are observed, which indicates adequate reliability of the one-dimensional model of the InCharge. The results suggest that the Peruvian version of the InCharge presents adequate psychometric evidence to measure the financial well-being of employees in a Peruvian context. Thus, it seeks to contribute to the advancement of the scientific study of financial well-being in Latin America. Received: 1 September 2023 / Accepted: 16 March 2024 / Published: 5 May 2024
