This study presents the psychometric proprieties of the Italian version of the Social Dominance Orientation7 (SDO7) Scale, originally developed by Ho et al. (2015). We recruited a convenience sam-ple (N = 497) to answer an online self-report questionnaire, including the SDO7 Scale and other rele-vant convergent and divergent measures. The confirmatory factor analysis revealed that SDO7 presents a satisfactory fit to the data, both as a two-correlated factor structure and as a one-dimensional measure. The two-correlated factor structure is confirmed as composed by two subdimensions as in the original version: the SDO-Dominance (SDO-D) and the SDO-Anti-Egalitarianism (SDO-E). Since the total SDO7 score measures people’s support for asymmetrical group relationships, the SDO-D is concerned with people’s support for dominant-submissive forms of intergroup relationships whereas the SDO-E refers to the desire to support intergroup inequalities. The scale and subscales also present satisfactory indexes of reliability as well as convergent and divergent validity.

Abstract
This study presents the psychometric proprieties of the Italian version of the Social Dominance Orientation7 (SDO7) Scale, originally developed by Ho et al. (2015). We recruited a convenience sam-ple (N = 497) to answer an online self-report questionnaire, including the SDO7 Scale and other rele-vant convergent and divergent measures. The confirmatory factor analysis revealed that SDO7 presents a satisfactory fit to the data, both as a two-correlated factor structure and as a one-dimensional measure. The two-correlated factor structure is confirmed as composed by two subdimensions as in the original version: the SDO-Dominance (SDO-D) and the SDO-Anti-Egalitarianism (SDO-E). Since the total SDO7 score measures people’s support for asymmetrical group relationships, the SDO-D is concerned with people’s support for dominant-submissive forms of intergroup relationships whereas the SDO-E refers to the desire to support intergroup inequalities. The scale and subscales also present satisfactory indexes of reliability as well as convergent and divergent validity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
