This study seeks to analyze the relationships among the components of national identity, political ideology, in its authoritarian and social dominance manifestations and expressions of subjective and social well-being in samples from 5 countries of Latin America. To accomplish this aim, a survey research was conducted in Brazil, Chile, Colombia, Mexico and Peru (n = 1039). Results show significant relationships between ideological expressions with some dimensions of identity. The authoritarian ideology is positively related to the identity components, whereas the social dominance ideology is inversely related to them. Relations among the components of identity and well-being have a positive association, and these relationships are more intense in the case of social well-being than in the case of subjective well-being. Nevertheless, some heterogeneity in these relations is observed by comparing countries. A general model of the relations among variables derived from three constructs was proposed, but this did not reach acceptable fit levels, being dismissed. It could be explained by the heterogeneity of the results by country.
