Assessment name: Interpersonal Reactivity Inventory (IRI)
Scale overview: The 28-item Interpersonal Reactivity Inventory (IRI) measures a four aspects of a person’s reactivity to others: Perspective -taking (IRI–PT), Empathic Concern (IRI–EC), Personal Distress, (IRI–PD), and Fantasy.
Author: Mark Davis
Response Type: Self-report 5-point rating scale.
There are four 7-item rating scales. Each item is rated from A to E with the anchors reflecting a degree of self-description: A = Does not describe me well, E = Describes very well.
Perspective -Taking (IRI–PT) measures cognitive empathy, or the tendency to see the world from others’ viewpoints: “I sometimes try to understand my friends better by imagining how things look from their perspective.”
Empathic Concern (IRI–EC) measures emotional empathy, or feelings of compassion for others in distress: “I often have tender, concerned feelings for people less fortunate than me.”
Personal Distress, (IRI–PD) measures self-focused responses to others’ suffering “When I see someone who badly needs help in an emergency, I go to pieces.”
Fantasy measures empathy for fictional characters: “I really get involved with the feelings of the characters in a novel.”
Davis (1983) reported adequate internal and test-retest reliability values from previous research. Correlations with other measures can be found in Davis (1983). The correlations suggest early support for concurrent validity.
