ABSTRACT
PURPOSE: The purpose of the study was to investigate the effect of work engagement (WE) on organizational citizenship behaviors (OCB) and ability to control career commitment (CC) in the relationship between work engagement and OCB. METHODS: Data were collected using structured self-report questionnaires from 205 nurses currently working at three national hospitals. Data were analyzed using descriptive statistics, ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis using the SPSS 21.0 program. RESULTS: Mean scores for each variable were: WE 3.77 (on a 7-point scale), OCB 3.41 (on a 5-point scale), and CC 3.05 (on a 5-point scale). As a result, comparison showed that all research variables were higher with age, OCB was higher with total clinical career, and CC was higher with higher education level. Total clinical career, WE and CC had a significant effect on OCB, and CC had a moderate effect on work engagement and OCB. These variables had a total explanatory power of 38% for OCB. CONCLUSION: The nurses' WE had a positive effect on OCB, and the CC showed a moderating effect on the relationship between WE and OCB. Therefore, we suggest that CC is an important factor in improving nurses' OCB.
