This study was conducted in order to examine the relationships among nursing students' clinical practice stress, emotional labor, and emotional intelligence. For this purpose, data were collected from 576 nursing students sampled from seven metropolitan cities and provinces during the period from March 1 to May 31, 2015. The subjects' mean score of clinical practice stress was 2.99, emotional labor 3.03, and emotional intelligence 4.88. Clinical practice stress was in a positive correlation with emotional labor, and emotional labor was in a negative correlation with emotional intelligence. When developing programs for mitigating their clinical practice stress and enhancing the effect of practice education, it is necessary to consider factors such as emotional labor, emotional intelligence, and environment for practice comprehensively.
