We propose a refined theory of basic individual values intended to provide greater heuristic and explanatory power than the original theory of 10 values (Schwartz, 1992). The refined theory more accurately expresses the central assumption of the original theory that research has largely ignored: Values form a circular motivational continuum. The theory defines and orders 19 values on the continuum based on their compatible and conflicting motivations, expression of self-protection vs. growth, and personal vs. social focus. We assess the theory with a new instrument in 15 samples from 10 countries (N=6059 basic values are organized into a coherent system that underlies and can help to explain individual decision-making, attitudes, and behavior. This coherent structure is arises from the social and psychological conflict or congruity between values that people experience when they make everyday decisions (Schwartz, 1992(Schwartz, , 2006a.The first and second columns of Table 1 list the ten basic values identified in the theory and their conceptual definitions. These values are likely to be universal because they are grounded in one or more of three universal requirements of human existence with which people must cope:needs of individuals as biological organisms, requisites of coordinated social interaction, and survival and welfare needs of groups. Each value is grounded in one or more of these three universal requirements of human existence (Schwartz, 1994). Table 1 about here 1 Google Scholar April 22, 2012 lists over 8200 citations to the three major articles that introduced the theory (Schwartz & Bilsky, 1987;Schwartz, 1992Schwartz, , 1994. which we separated the thought and action facets, revealed that the thought facet alone, and not the action facet, accounted for this association.Turning to security values, Schwartz's (1992) definition included two conceptual facets, personal security (safety for self) and societal security (stability and order in society). A study in Italy, Spain, and Germany separated these facets of security when predicting perceptions of the consequences of immigration (Vecchione, et al., in press). In a structural equation model, societal security strongly predicted perceptions that immigration has negative consequences in all three countries, whereas personal security did not predict at all. This revealed that the aspect of security values that led to perceiving immigration as threatening was concern for the impact of immigration on societal stability and order, not concern for one's personal safety.These examples illustrate the potential benefits of a refined theory that partitions the motivational continuum of values into a larger number of more narrowly defined, conceptually
