The Mediating Role of General Self-Efficacy in the Relationship Between the Big Five Personality Traits and Perceived Stress: A Weekly Assessment Study

A cross-sectional study design may not be a reliable procedure for indicating the effects of stable individual structures on transient conditions in stress situations. In order to address this gap, we aimed to explore the role of the direct and indirect effects of the big five personality traits with the mediating effect of self-efficacy on perceived stress using a weekly diary method. The sample comprised 79 full-time workers who filled in a questionnaire that included the Big Five Inventory and General Self-Efficacy Scale at the initial administration and the Perceived Stress Scale over 12 weeks. Data were analysed using hierarchical linear modelling to examine the relationship between the big five personality traits and weekly perceived stress and the mediating role of general self-efficacy in this relationship. The results indicated that neuroticism and extraversion were significantly associated with general self-efficacy and perceived stress. The results further indicated that general self-efficacy fully mediated the relationship between extraversion and perceived stress. General self-efficacy partially mediated the relationship between neuroticism and perceived stress. Our findings highlight the importance of personality and self-efficacy for predicting perceived stress. Implications for future research and practice are discussed.
