Abstract: Background: Compulsive buying-shopping disorder (CBSD) is associated with high materialistic values endorsement and excessive purchasing of consumer goods. A subgroup of individuals with CBSD engage in socially unacceptable behaviors to continue shopping despite negative consequences. This investigation aimed at exploring possible links between ego-oriented shopping-related decisions, materialism, symptoms of CBSD and close-to-everyday moral decision making. Methods: In study 1, patients with CBSD were interviewed to develop a list of conflict situations, capturing typical shopping-related dilemmas. In study 2, the shopping-related dilemmas from study 1, standardized close-to-everyday moral dilemmas, the Material Values Scale and Pathological Buying Screener were administered to a web-based convenience sample ( n = 274). Results: The main effects of a moderated hierarchical regression analysis revealed an association of more ego-oriented shopping-related decisions with both higher materialistic values endorsement and more CBSD symptoms, but not with everyday moral decision-making. However, a more egoistic everyday moral decision making style moderated the effect of CBSD symptoms on ego-oriented shopping related decisions. Conclusions: The findings indicate that a more egoistic everyday moral decision making style is not directly linked to domain-specific shopping-related decision making but strengthens the link between symptoms of CBSD and ego-oriented shopping-related decisions.
