AIMS: Health behaviours - alcohol drinking, smoking, poor diet and physical inactivity - are influenced by various psychosocial factors. Despite evidence linking work stress and personality constructs independently to health behaviours, only limited literature is available on the relationship between work stress, personality and health behaviours. The aims of the thesis are: (1) to examine the potential role of overcommitment (OC) personality in the relationship between work stress defined by the Effort-Reward Imbalance (ERI) model and health behaviours; (2) to investigate the potential role of perceived control (PC) in the relationship between ERI, OC and health behaviours. METHODS: This project used data from the HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) study, which randomly selected people aged 45 to 69 years from population registers in Russia, Poland and the Czech Republic. A two-wave cohort study for drinking and smoking outcomes (n= 7,513) and a cross-sectional study for dietary outcomes (n= 11,012) were analysed by logistic regression and structural equation modelling. RESULTS: In terms of the potential role of OC in the relationship between ERI and health behaviours, OC and ERI may have bi-directional relationship; the effect of OC on ERI was stronger than the other direction in the middle-aged and older populations. Thus, antecedent role of OC in the relation between ERI and health behaviours was statistically significant, but mediator role of OC was not. With regards to the potential role of PC in the relationship between OC, ERI and health behaviours, both ERI and PC partially mediated the effects of OC on health behaviours; ERI and PC may have bi-directional relationship. CONCLUSION: This thesis will contribute to deeper understanding of intersecting pathways by which work stress (ERI) and personality constructs (OC and PC) jointly influence health behaviours, thereby providing insight into research, practice and policy.
