Schwartz's value system (SVS) has been widely used in diVerent disciplines (e.g., psychology, management, and marketing). Although the value structure seems to be validated when data are analyzed through multidimensional scaling, we show that the quasi-circumplex structure of human values is not supported when conWrmatory analysis approaches (e.g., CIRCUM and constrained conWrmatory factor analysis) are used. Based on two samples of French and Swiss respondents, conWrmatory tests of SVS provide little support for its quasi-circumplex structure, mainly due to problems of construct and discriminant validity resulting from multicollinearity between value types.
