Relationships Between Occupational Stress and Work Life Quality: The Moderator Role of Psychological Capital

The purpose of this study was to investigate the moderator role of psychological capital in relationships between occupational stress and work-life quality among the staff of the University of Bojnord. In this cross-sectional study, the population was all employees (faculty and non-faculty members) working at the University of Bojnord. Totally, 150 employees were selected by stratified random sampling. The questionnaires used in this study were occupational stress, psychological capital, and work-life quality. The research hypothesis was examined by the multiple regression analysis in SPSS V22 0 Statistical Analysis Software. According to the findings, the correlation coefficient between occupational stress and work-life quality (r=-0.595, p<0.0001) and between psychological capital and work-life quality (r=0.421, p<0.0001) was significant, statistically. The interaction of occupational stress and psychological capital, beyond the effects of the main variables, caused an increase of 2.8% in the variance of the model, indicating that these variables have a significant interaction with each other in predicting the quality of work-life (ΔR2=0.028, ΔF= 6.15, p< 0.02). The results also showed the importance of psychological capital as a moderator of the relationships between occupational stress and work-life quality among the university staff. To reduce the effects of occupational stress on the quality of work-life, university authorities are advised to enhance the psychological capital of their employees through practical-training protocols.
