Tóm tắt	The Partisan Identity Scale measures strength and direction of psychological attachment to a political party, encompassing both party preference and emotional party identification. Foundational since Campbell et al.'s American Voter (1960), the measure distinguishes party affiliation (which party one is registered with) from party identification (psychological identity with a party as a social group). Partisan identity is among the strongest predictors of voting behavior, political attitudes, and interpretation of political information, functioning as a 'perceptual filter' through which voters process news.	The Political Ideology Scale measures individual self-placement on a left-right political spectrum, capturing fundamental preferences for government role, economic organization, and social values. The single-item self-placement measure (most common) asks respondents to rate themselves on a 0-10 or 0-100 continuum; multi-item versions assess distinct ideological dimensions (economic policy, social policy, nationalism). The left-right axis remains the dominant organizing principle of political competition globally, predicting party choice, policy preferences, and electoral behavior despite critiques that it oversimplifies multidimensional political space.	The Populism Attitudes Scale measures individual propensity toward populist political orientations, including Manichean worldview (pure people vs. corrupt elites), belief in popular sovereignty, and anti-elitism. Developed by Akkerman, Mudde, and Zaslaysky (2014), the eight-item scale distinguishes populist attitudes from left-right ideology, authoritarian attitudes, and distrust of institutions. It captures voters' susceptibility to populist political messaging across left-wing and right-wing populist movements globally, from Latin American left-populism to European right-wing populism.
