概要	The Collectivism-Individualism Scale is a self-report measure designed to assess individual differences in independent versus interdependent self-construal and cultural orientation toward individualism and collectivism. Developed by Singelis (1994) and refined through subsequent research by Triandis and colleagues, the scale operationalizes self-concept dimensions as independent (autonomous, unique) or interdependent (connected, embedded in relationships). It has become a fundamental tool for cross-cultural psychology research.	The Social Dominance Orientation Scale (SDO) is a self-report measure developed by Pratto, Sidanius, Stallworth, and Malle in 1994 to assess individual differences in preference for group-based hierarchy and inequality. The scale measures the extent to which individuals support dominance of some groups over others, reject egalitarianism, and accept hierarchical social organization. It has become central to social dominance theory and is widely used in political psychology and intergroup relations research.
