GIGER, Jean-Christophe et al. Metric Evidences of the adaptation of the Social Dominance Scale in a portuguese sample. Aval. psicol. [online]. 2015, vol.14, n.1, pp. 143-151. ISSN 1677-0471.

This study aims to present evidences of the validity of the social dominance orientation scale for Portuguese population. Participants were 910 Portuguese people. Most of them were women (58.7%), with ages ranging from 18 to 81 years (M=34.09; SD=11.57). Reliability analysis, exploratory factor analysis (n=455) and confirmatory factor analysis (n=455) were carried out. Results supported a two-component model for the SDO scale, which displayed a better fit than the original one-factorial structure. The scale showed good psychometric properties. In conclusion, the SDO is a psychometrically adequate instrument, being better represented by a two-component model. Future studies should examine the criterion validity through the analysis of the relationship of social dominance with ambivalent sexism, neosexism and authoritarian personality, among others

Palabras clave : dominance; factor structure; internal consistency; exploratory factor analysis; confirmatory factor analysis.
