Another study by Péloquin and Lafontaine (2010) adapted the IRI to specifically measure empathy in couples rather than individuals.Péloquin, K., & Lafontaine, M. (2010). Measuring empathy in couples: Validity and reliability of the Interpersonal Reactivity Index for couples. Journal of Personality Assessment, 92(2), 146-157. This was achieved by rewording some phrases used in the original, for example replacing references to "people" and "somebody" to be "my partner," etc. Several couples were also asked to return after twelve months to be re-evaluated. This new version still adequately measured empathy as well as demonstrated predictive validity in the returning couples, correlating relationship satisfaction and each partner's empathy.
