Abstract

OBJECTIVES
The aim of this study was to test the reliability and validity of the Korean version of Interpersonal Reactivity Index (K-IRI).
METHODS
A total of 484 participants were included in this study. Internal consistency and test/retest reliability (n=35) were examined. Criterion validity of the K-IRI was assessed against Affective Dimension of the 3D-Wisdom Scale. Factor analyses were also performed using principal component analysis with varimax rotation.
RESULTS
The internal consistency of the K-IRI was 0.80, and test-retest reliability was 0.76. Criterion validity was evaluated by correlating the K-IRI with the Affective Dimension of 3D-Wisdom Scale (r=0.31). Factor analyses revealed factor structures similar to the original IRI.
CONCLUSION
The K-IRI appeared to be a reliable and valid instrument for assessing empathy in the Korean population. This suggests that this scale may be applicable in clinical trials, research, and clinical practice.
