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.MH Davis. "Measuring individual differences in empathy: Evidence for a multidimensional approach". Journal of Personality and Social Psychology, 1983 v.44:1 p.113-126 The tool is widely used—the paper describing it , published in 1983, has been cited about 10,000 times, according to Google Scholar.User profiles for "MH Davis" on 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". Versatility  Adaptability In addition to the original English version, the IRI has proven equally effective when translated into other languages and for diverse populations. A study by De Corte et al. (2007) demonstrated this versatility by translating the IRI into Dutch.De Corté, K., Buysse, A., Verhofstadt, L. L., Roeyers, H., Ponnet, K., & Davis, M. H. (2007). Measuring empathic tendencies: Reliability and validity of the Dutch version of the Interpersonal Reactivity Index. Psychologica Belgica, 47(4), 235-260. The researchers found that their translation is just as valid and reliable as Davis's original version, albeit in their educated, still Westernized sample. However, limitations to its versatility have been found in more disparate populations. Garcia-Barrera, Karr, Trujillo-Orrego, Trujillo-Orrego, and Pineda (2017) translated and modified the IRI into a Colombian Spanish version.Garcia-Barrera, M. A., Karr, J. E., Trujillo-Orrego, N., Trujillo-Orrego, S., & Pineda, D. A. (2017). Evaluating empathy in Colombian ex-combatants: Examination of the internal structure of the Interpersonal Reactivity Index (IRI) in Spanish. Psychological Assessment, 29(1), 116-122. This version was used to measure empathy in Colombian militants returning to society after having seen combat. The study encountered more difficulty in obtaining valid and reliable findings than previous studies. They attributed this difficulty largely due to the lack of education of the participants, which resulted in the introspective and abstract items of the IRI being difficult to understand.
