This study aimed to identify core competencies in new-graduate nurses (NGNs) by determining which competencies affected their organizational socialization (OS) and turnover intention (TI) in their 1st year of employment.

NGNs face stressful transitions with expanded nursing responsibilities that motivate them to leave their jobs. Therefore, NGN turnover in the 1st year of practice is higher than the overall nurse turnover rate. Previous research suggested that NGNs' competency levels affect their OS and TI. However, little research has been done to determine which competencies affect these variables.

Multiple linear regression analysis was performed on cross-sectional survey data to determine the effects of NGN work competencies on OS and TI.

Health promotion, supervision, interpersonal communication, and direct care competencies significantly predicted NGNs' OS, and computer technology competency significantly predicted NGNs' TI.

NGNs should be given early opportunities for expanded hands-on clinical experiences along with clear awareness of the organization's goals and values. Moreover, they should be offered roles that take advantage of their computer technology skills and that challenge them to contribute to their organization and nursing care in new ways.
