Mediation effects of overcommitment on effort, reward, insomnia, and well-being as moderated by gender, age, and job position.

This study aimed to detect the mediation effect of over-commitment between occupational stress, insomnia, and well-being; and the moderating role of gender, age and job position are also to be analyzed. One thousand six hundred eighteen valid samples were recruited from electronic manufacturing service industry in Hunan Province, China. All the data were collected by selfrated questionnaires after written consent. This paper introduced Effort-Reward- Insomnia-Well-being model, and it was fitted and validated through the structural equation model analysis. The results of single factor correlation analysis indicated that the coefficients between most of the items and dimensions presented statistical significance. The final fitting model had satisfactory global goodness of fit (CMIN/DF=3.99, AGFI=0.926, NNFI=0.950, IFI=0.956, RMSEA=0.043). Both of the measurement model and structural model had acceptable path loadings. Effort associated with insomnia indirectly and related to well-being directly and indirectly; reward could have either directly associated with insomnia and well-being, or indirectly related to them through over-commitment. Covariates as gender, age and position made differences on the association between occupational stress and health outcomes. Over-commitment had the ability to mediate the relationships between effort, reward, and health outcomes, and mediation effect varied from different working conditions and outcomes under different covariates.
