Authoritarianism, social dominance and social values: Group-based dominance and opposition to equality as independent factors

.

Several authors have studied the relationship between Social Dominance Orientation (SDO) and Right-Wing Authoritarianism (RWA) (Altemeyer, 1998; Pratto, Sidanius, Stallworth & Malle, 1994; Roccato & Ricolfi, 2005; Weber & Federico, 2007), as well as their relation with values (Cohrs, Moschner, Maes & Kielman, 2005; Duriez, Van Hiel & Kossowska, 2005; Heaven & Connors, 2001). As far as SDO is concerned, recent research has shown the existence of a bidimensional structure: opposition to equality (OEQ) and group-based dominance (GBD) (Jost & Thompson, 2000; Sidanius & Peña, 2002; Silván-Ferrero & Bustillos, 2007). The aim of this study is to deepen into the relationship between RWA and the dimensions of SDO, as well as their relation to values. A total of 463 subjects participated in the study and measures of values (Schwartz, 1992), RWA (Zakrisson, 2005), and SDO (Sidanius & Pratto, 1999) were used. Significant correlations between RWA and SDO as well as the relationship among the SDO dimensions were found. The SEM showed that the bidimensional model had a better fit than the unidimensional one. Entering values as covariates, and RWA, SDO and its dimensions as dependent variables, several GLM analyses were performed, showing that the model was significant for RWA, SDO, BDG, and OEQ. Results also showed that RWA was better predicted by the value dimension of conservation while SDO by the dimensions of self-enhance and self-transcendence. Moreover, while the BDG and OEQ were similar in self-transcendence, BDG had a higher level of self-enhance and conservation. Finally, results relevance for theoretical and applied dimensions is discussed.
