The relationship between personality traits and happiness: the mediating role of emotional regulation

Background Understanding the factors contributing to happiness in the nursing profession is essential, particularly considering the high levels of stress associated with the job. This study aimed to explore the role of emotion regulation in mediating the relationship between personality traits and nurses' happiness.Objective This study aimed to explore the relationship between personality traits and happiness by examining the mediating role of emotion regulation.Methods A cross-sectional study was conducted with 324 Jordanian and 408 Saudi nurses. Data, including the Big Five personality traits, happiness levels, and measures of emotional regulation, were collected through an online survey. The model's fit and explanatory capability were verified by Structural Equation Modeling (SEM) using SmartPLS 3.Results In the structural model, agreeableness had a significant effect on happiness, influencing both reappraisal and suppression. Extraversion strongly influences happiness, positively affects reappraisal, and negatively affects suppression. Neuroticism hampers happiness and reappraisal, and has a detrimental effect on suppression. Openness had a positive effect on suppression, whereas consciousness positively affected happiness. Mediation analysis revealed direct effects on happiness, with varying indirect contributions from emotional regulation. Multiple-group analysis revealed no significant differences between Jordan and Saudi Arabia in the association between personality traits and happiness.Conclusion The findings emphasize the nuanced effects of agreeableness, extraversion, neuroticism, consciousness, and openness on happiness, mediated by emotional regulation. Implementing specific interventions to improve emotional regulation can increase nurses' happiness regardless of their personality traits. The lack of significant differences between Jordanian and Saudi nurses implies that these relationships are consistent across cultures, offering valuable information for cross-cultural healthcare interventions.
