Psychometric Properties of Multidimensional Dispositional Greed Assessment (MDGA); and investigate the role of culture and sociodemographic characteristics on greed

Abstract This article analyzes the psychometric properties of the Multidimensional Dispositional Greed Assessment (MDGA), which is designed to measure dispositional greed in adults. Dispositional greed is recognized as a key personality trait in social psychology and can have profound effects on individuals’ behaviors and decision-making processes. In this study, we examined the factor structure of the 20-item MDGA scores using Confirmatory Factor Analysis (CFA). This analysis was conducted on a sample of adults from two countries, Iran and Azerbaijan, comprising 607 individuals. The aim of this research was to assess the validity and reliability of this tool in measuring dispositional greed across different cultures. The results of the confirmatory factor analysis indicated that a three-factor structure fits the data well and accounts for a significant portion of the variance in the scores (sbX2 = 426.18 (p < 0.01); SRMR = 0.048; RMR = 0.061, GFI = 0.93, AGFI = 0.92, RFI = 0.96, IFI = 0.98, PNFI = 0.83, NNFI = 0.97, NFI = 0.97; CFI = 0.98; RMSEA = 0.051). The Cronbach’s alpha values for the three factors Insatiable (0.873), Desire (0.875), and Retention (0.924) were obtained. Significant differences in the levels of greed were also observed among the cultural and sociodemographic variables. These findings help us gain a better understanding of the various dimensions of dispositional greed and suggest that MDGA can serve as an effective self-report tool for researchers in this field. Additionally, we emphasize the importance of this tool for future research and provide recommendations for various research domains. In particular, examining the cultural and social influences on dispositional greed, as well as its relationship with economic and social behaviors, can be vital topics that warrant further investigation. Ultimately, this study can contribute to the development of theories and models related to dispositional greed and enhance our understanding of this personality trait across different societies.
