Support for exclusionism as an independent dimension of social dominance orientation in mainland China

Three studies using exploratory and confirmatory factor analyses provided consistent evidence for a three-factor model of the social dominance orientation (SDO) in Mainland China. Support for exclusionism, which was not found in previous research, emerged as an independent SDO factor (Studies 1, 2, and 3). In Study 2, this factor predicted SDO difference between a high status group (managers) and a low status group (entry-level employees). In Study 3, this factor correlated positively with authoritarianism and negatively with altruism. These results provided evidence for the validity of this new SDO factor. The findings are discussed in terms of their relations to China’s cultural tradition and contemporary economic development.
