This research is a descriptive study intended to identify the factors involved in the influence of the emotional intelligence of nursing students on their career decision-making self-efficacy and career decision levels. The correlations among the major variables were analyzed by calculating the Pearson's correlation coefficients. To identify the effects of the subjects' general characteristics and emotional intelligence on their career decision-making self-efficacy and career decision levels, a multiple regression analysis was conducted. The analysis results showed that there were positive relationships among emotional intelligence, career decision making and career decision-making self-efficacy. The factors influencing career decision-making self-efficacy were gender (β=-.155), motivation to find employment (β=-.145), use of emotions (β=.236), emotional control (β=.197), and understanding of others' emotions (β=.157). In addition, the factors affecting the subjects' career decision level were the year level (β=.273), motivation to find employment (β=-.145), motivation to obtain others' recommendation (β=-.138), and emotional control (β=.223). Hence, sufficient endorsement from school or home is required with regard to the roles and duties of a nurse, in order to motivate future students to select the nursing degree. Furthermore, it is suggested that emotional intelligence may be improved when the degree program provides a higher proportion of emotional education.
