Abstract
Emotional intelligence and empathy are crucial in patient–physician relationships and clinical outcomes. It has been reported that both emotional intelligence and empathy decrease as students advance through medical school. This study aimed to validate Japanese versions of the Trait Emotional Intelligence Questionnaire–Short Form （TEIQue–SF）, developed by Petrides and Furnham （2001）, and the Jefferson Scale of Physician Empathy （JSPE）, developed by Hojat et al. （2001）.
1）The TEIQue–SF and JSPE were translated and administered to 370 medical students. Valid responses were obtained from 321 students（88%）.
2）Cronbach’s alpha for internal reliability was high for both the TEIQue–SF （0.87） and the JSPE （0.89）. All item total score correlations were positive for both the TEIQue–SF （range, 0.29 to 0.64） and the JSPE （range, 0.27 to 0.72）.
3）Cronbach’s alpha was smaller if an item was deleted than if all items were included for both the TEIQue–SF （0.84–0.85） and the JSPE （0.81–0.86）.
4）Factor analysis of both the TEIQue–SF and the JSPE revealed that the Japanese versions had some structural differences from the original versions. However, criterion–related analysis showed that the TEIQue–SF and the JSPE were highly correlated with the NEO–Five Factor Inventory, a measure of the Big Five personality traits.
5）These findings provide support for the construct validity and reliability of the Japanese versions of the TEIQue–SF and the JSPE when used for medical students. Further investigation is needed.
