The purpose of this study was to demonstrate the effectiveness of diversion buying for stress release. Diversion buying was examined by survey, and it was found that women engaged in it more often than men. In Experiment 1, diversion buying was divided into an expenditure factor and an acquisition factor, in order to examine which was more effective for stress release; both had a significant main effect. The effectiveness of the acquisition factor was confirmed in Experiment 2. In Experiment 3, the expenditure factor was divided into the amount available for expenditure and the amount spent, in order to examine the effectiveness of each. It was shown that a certain amount of expenditure was needed for stress release; however, a high expenditure rate (spending most of the money) did not relieve stress.
