Summary	The Relative Deprivation Scale measures the subjective sense that one's own group (fraternal/group relative deprivation) or oneself (egoistic/individual relative deprivation) is unjustly worse off than a relevant comparison standard, accompanied by feelings of resentment. Building on Runciman (1966) and synthesized by Smith and colleagues (2012), it captures the three-component process, cognitive comparison, appraisal of injustice, and affective resentment, that links inequality to political action.	The Intergroup Threat Scale operationalizes intergroup (originally integrated) threat theory (Stephan & Stephan), which holds that prejudice toward an out-group arises from perceived realistic threats (to the in-group's resources, power, or welfare) and symbolic threats (to its values, beliefs, and worldview). It is a self-report measure widely used to explain attitudes toward immigrants and other out-groups in political psychology.
