Argentinian adaptation of the new Social Dominance Orientation scale (SDO7)

Abstract

The present work adapted the seventh scale of Social Dominance in Argentina in its two versions: long (16 items) and short (eight items; Ho et al., 2015). The psychometric properties of the scale were studied and its factorial structure was evaluated. We analyzed differences in SDO as regards sex, age, socioeconomic self-positioning and political orientation. We worked with a convenience sample (n = 1573, short scale; n = 590, long scale) between 18 and 60 years. The scale shows evidence of reliability consistent with the theory. The factor analysis confirms the bifactorial structure of the scale, finding two dimensions: SDO-Dominance and SDO-E Egalitarianism. A positive correlation was found between right-wing political self-positioning and SDO.
