概要	The Interpersonal Reactivity Index (IRI) is a 28-item self-report measure developed by Mark H. Davis in 1980 to assess individual differences in empathy as a multidimensional construct. Rather than treating empathy as a single trait, the IRI measures four distinct empathic dimensions: perspective-taking, fantasy, empathic concern, and personal distress. It has become the most widely used multidimensional empathy measure in psychological and social science research.	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.
