The hierarchical structure of the Interpersonal Reactivity Index

The hierarchical factor structure of the Interpersonal Reactivity Index (IRI) (Davis, 1980) inventory was investigated with the Schmid-Leiman orthogonalization procedure (Schmid & Leiman, 1957). The sample consisted of 409 college students. The analysis found that the IRI could be factored into four first-order factors, corresponding to the four scales of the IRI, and two second-order orthogonal factors, a general empathy factor and an emotional control factor.
