The Influence of Grit on Turnover Intention of University Hospital Nurses: The Mediating Effect of Job Involvement

Abstract

This study aimed to confirm the mediating effect of job involvement in the relationship between grit and turnover intention among nurses working at university hospitals. Participants included 437 nurses from university hospitals located in C city, Gyeongnam. Data were collected from January 8 to 19, 2018, using self-report questionnaires. Data were analyzed using the t-test, analysis of variance, Scheffe's test, Pearson's correlation coefficient, and multiple regression, with the SPSS/22.0 program. A mediation analysis was performed according to the Baron and Kenny, and bootstrapping methods. There were significant relationships between grit and job involvement (r=.40, p<.001), grit and turnover intention (r=-.29, p<.001), and turnover intention and job involvement (r=-.52, p<.001). Job involvement showed partial mediating effects in the relationship between grit and turnover intention. Grit increased job involvement and lowered turnover intention. Therefore, to reduce nurses' turnover intention, it is necessary to develop a program and strategies to increase their grit.
