Social dominance orientation (SDO) represents an individual tendency to support already existing hierarchical social structures. Recent research has indicated that this phenomenon has a two-factor structure: SDO-Dominance (SDO-D) and SDO-Egalitarianism (SDO-E). The aim of this study is to adapt the New Social Dominance Orientation Scale (SDO7), developed by Ho et al. (2015), to measure the two-factor structure of SDO for the Turkish context. For this purpose, SDO7 was applied to 730 participants (222 men, 507 women and one missing) from two different samples. Additionally, an Ambivalent Sexism Scale, General System Justification Scale (sample-1), Gender Related System Justification Scale (sample-2) and a Short Question Form (which was created to determine participants' levels of support for social welfare, income justice, and war) were also applied. Results of confirmatory factor analysis support a four-factor structure that contains both substantive and methodological items. The results for construct validity showed that SDO, SDO-D, and SDO-E were positively correlated with benevolent and hostile sexism and general system justification (sample-1), and gender related system justification (sample-2). Furthermore, in order to test construct validity the semi-partial correlations between SDO-D and criterion variables and those between SDO-E and criterion variables were compared. Results indicated that, only 3 of the 12 different semi-partial correlation comparisons were significant. These results implied that SDO-D and SDO-E were not consistently different in terms of their relations with the criterion variables measured for this study. Therefore, the results of this study indicate that SDO7 has a four-factor structure that contains both substantive and methodological dimensions of social dominance orientation in Turkey. However, theoretically SDO-E and SDO-D are not clearly separated from one another. Thus, SDO7 can be used as a one-factor scale which includes different aspects of social dominance orientation in Turkey.
