The development of the Japanese version of the Dispositional Greed Scale

The purpose of this study was to develop the Japanese version of the Dispositional Greed Scale (J-DGS), and to examine its reliability and validity. The participants in this study were Japanese university students (N = 856). The principal component analysis indicated that the J-DGS had a unidimensional structure and adequate internal consistency. There were positive associations between the J-DGS and envy, psychological entitlement, materialism, impulsive buying behavior, extravagance, and neuroticism. Conversely, J-DGS scores were negatively correlated with self-control, self-esteem, life satisfaction, and agreeableness. These results, which are consistent with previous studies, confirmed the concurrent validity of the J-DGS.
