Relationship between Organizational Justice and Mental Health among Hospital Nurses, as well as The Effect of Age.

Abstract

Objectives: This study aimed to clarify the relationship between organizational justice and mental health among nurses, and to examine whether this association varies with age.

Method: A self-administered questionnaire survey was given to hospital nurses, and 219 nurses were included for analysis.

Results: Multiple regression analysis using mental health (K6) scores as the dependent variable and organizational justice (OJS-J) scores as the independent variable revealed a significant association between K6 scores and OJS-J scores. The subjects were then divided into two groups by age (younger age versus older age), and a stepwise multiple regression analysis was conducted with K6 scores as the dependent variable and OJS-J scores as the independent variable for each group. Subsequently, stepwise multiple regression analysis was conducted using the OJS-J subscale scores (procedural justice, distributive justice, interpersonal justice, and informational justice) as independent variables, and a significant association was found between K6 scores and procedural justice scores in the final model for the younger age group.

Conclusion: The present results suggest that efforts to improve organizational justice are necessary to improve the mental health of nurses, and that it is important to take procedural justice into consideration, especially in workplaces with many younger nurses.
