본 연구는 신입간호사의 정서지능, 자아탄력성, 핵심자기평가가 간호업무수행에 미치는 영향을 파악하는 서술적 조사연구이다. 대상자는 경기도에 소재한 800병상 이상의 종합병원 2곳에서 근무하는 12개월 미만의 신입간호사 114명이었다. 자료 수집은 2013년 7월부터 11월까지 간호업무수행, 정서지능, 자아탄력성, 핵심자기평가에 대해 구조화된 설문지를 이용하여 측정하였다. 연구의 결과, 신입간호사의 교육 정도, 직무만족도, 근무부서 업무만족도에 따라 간호업무수행 정도의 차이가 있었으며, 정서지능, 자아탄력성, 핵심자기평가가 높을수록 간호업무수행 정도는 높았다. 정서지능, 교육수준, 핵심자기평가와 직무만족도는 간호업무수행 정도를 잘 예측하는 변수로 확인되었고, 간호업무수행 정도를 33% 설명하는 것으로 나타났다. 따라서 신입간호사의 교육 정도와 직무만족도를 고려하여 신입간호사 오리엔테이션부터 간호업무수행 외에 정서지능과 핵심자기평가를 포함한 실제적인 실무적응 훈련교육이 필요하다. This study is a descriptive research of investigating the correlation between new nurses' nursing performance, emotional intelligence, self-resiliency and core self-evaluation. The subjects were 114 new nurses working for less than 12 months at two different hospitals with over 800 beds located in Gyeonggi-do. Between July and November, this study collected the data measured by using a structured questionnaire survey for nursing performance, emotional intelligence, self-resiliency and core self-evaluation. As a result, it was found that there was a difference in the degree of nursing performance according to new nurses' education level, job satisfaction, and working position task satisfaction, and that the higher the emotional intelligence, self-resiliency and core self-evaluation were, the better the nursing performance was. As for emotional intelligence, education level, core self-evaluation and job satisfaction, it was found that they were variables to well predict the degree of nursing performance, and explained 33% of variance in nursing performance. Accordingly, it is necessary to provide actual field-adaptive training education including emotional intelligence and core self-evaluation other than nursing performance from new nurses' orientation in consideration of education degree and job satisfaction.
