The Interpersonal Reactivity Index (IRI) is a published measurement tool for the multi-dimensional assessment of empathy. It was developed by Mark H. Davis, a professor of psychology at Eckerd College. The tool is widely used—the paper describing it has been cited 3697 times, according to Google Scholar.
The tool is a self-report comprising 28-items answered on a 5-point Likert scale ranging from “Does not describe me well” to “Describes me very well”.
The four subscales are:
- Perspective Taking – the tendency to spontaneously adopt the psychological point of view of others.
- Fantasy – taps respondents' tendencies to transpose themselves imaginatively into the feelings and actions of fictitious characters in books, movies, and plays.
- Empathic Concern – assesses "other-oriented" feelings of sympathy and concern for unfortunate others.
- Personal Distress – measures "self-oriented" feelings of personal anxiety and unease in tense interpersonal settings.
