Work and Lifestyle Factors Influencing Job Satisfaction of Japanese Civil Servants: A 5-Year Longitudinal Study

Objective Although work, family, and lifestyle factors were associated with job satisfaction, prospective studies are lacking. This longitudinal study clarified the predisposing factors for job satisfaction. Methods Datasets were obtained from the Japanese Civil Servants Study and included 1429 participants. We assessed the relationship between job satisfaction and specific work and lifestyle factors. Logistic regression analyses evaluated the association between deteriorating job satisfaction and poor work and lifestyle factors at baseline and changes in these factors at follow-up. Results Poor sleep quality and limited job control at baseline were associated with deterioration in job satisfaction. Furthermore, deterioration in job control and work-to-family conflict at follow-up was associated with job dissatisfaction. Conclusion Work and lifestyle characteristics were associated with job dissatisfaction. Employees with limited job control and high work-to-family conflict at baseline were more likely to develop job dissatisfaction.
