Isms dimensions: toward a more comprehensive and integrative model of belief-system components.

Psychological research on beliefs, values, worldview, and ideology has been limited by inadequate structural models to organize the plethora of constructs. The present studies investigate the potential of a dimensional model based on lexical, dictionary-represented -ism concepts to form an organizing structural model. Four isms factors found previously in college samples are shown to replicate in community-sample data with better controls for acquiescent responding. But analyses also reveal a 5th factor involving egalitarianism and inequality-aversion, increasing the comprehensiveness of the structural model. Relations of frequently used constructs (values, authoritarianism, social dominance orientation) to the isms dimensions are detailed, demonstrating both the integrative and value-adding potentials of the model. The possibility of potential additional nonlexical factors (Trust in Government, Ethnocentrism, Xenophobia, and Nativism) is evaluated. Factors identified in these studies are demonstrated to show interesting relations with political-party preference, subjective well-being, and change over time in the Big Five personality dimensions.
