Mediating role of occupational stress and job satisfaction on the relationship between neuroticism and quality of life among Chinese civil servants: a structural equation model

Abstract

Background: Knowledge on the quality of life (QOL) of civil servants is limited. Therefore, the aims of this study were to investigate the QOL of civil servants, and examine whether occupational stress and job satisfaction mediated the association between neuroticism and QOL in civil servants from Shandong, China. Methods: The cross-sectional study included 559 civil servants aged 27 to 60 years from Shandong province in China. Participants completed questionnaires assessing neuroticism, occupational stress, job satisfaction, and QOL. Structural equation modeling (SEM) was conducted to examine the hypothetical model. Results: Among the civil servants, the average score for QOL was 75.49 ± 14.73. The SEM analysis showed a good fit of the data to the hypothesized model. Neuroticism, occupational stress, and job satisfaction explained 38% of the variance of QOL. Neuroticism was positively correlated with occupational stress and negatively correlated with job satisfaction and QOL. A strong direct effect (− 0.386, P < 0.01) and moderate indirect effect (− 0.133, P < 0.01) of neuroticism on QOL mediated by occupational stress and job satisfaction were observed. In addition, a direct effect (− 0.197, P < 0.01) and an indirect effect (− 0.044, P < 0.01) of occupational stress on QOL mediated by job satisfaction were also observed. Conclusions: Occupational stress and job satisfaction partly mediated the relationship between neuroticism and QOL among Chinese civil servants. Thus, selecting individuals with a low level of neuroticism as civil servants, reducing occupational stress, and increasing job satisfaction may be important measures to improve their QOL.

A Study on the Relationship Between Self-Efficacy, Psychological Resilience, and Job Burnout of Grassroots Civil Servants

“…In this study, grassroots civil servants have a high level of self-efficacy, and similar results have been reported by Li et al 17 Thus, although grassroots civil servants have heavy tasks and responsibilities at present, their sense of self-efficacy has not decreased. The self-efficacy of grassroots civil servants tends to increase gradually with age and working time, which is the same as the research results of Xu et al 18 Married grassroots civil servants own higher self-efficacy, possibly because they have more life experience and are more rational in solving problems at work 19 …”

Smart working in the travel agencies and employees’ quality of life

“…Alrawadieh et al (2021) confirmed that job satisfaction is positively related to quality of life. Past studies have also confirmed the influence of job satisfaction and quality of life (Kong et al, 2020;Ogaji et al, 2020). Accordingly, the current study posits the following hypothesis:…”

Effort-reward imbalance and job strain index associated with health-related quality of life for civil servants in a national survey: the mediation effect of job support and over-commitment

“…In addition, a study for Chinese civil servants stated the average score for quality of life (QOL) was 75, which was significantly affected by neurotic personality traits, occupational stress, and job satisfaction. Occupational stress and job satisfaction acted as mediators on the association between neuroticism and QOL [28]. Despite discovering negative associations with QOL for civil servants with occupational stress, Kong's study cannot discriminate the intensities of the 3 models on QOL.…”
