Intergroup Threat Scale

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.
