A Structural Equation Model of Perceived Stress Level Related to Personality Trait, Chronotype Profile, and Eating Behaviour

Background: high levels of stress have hazardous impacts on nurses’ health, well-being, job satisfaction, and abilities to cope with the job demands, which in turn may impact the provision of quality patient care, which is essential for universal health coverage. Aim: to investigate the relationship of perceived stress related to personality traits, chronotype, and eating behaviour among hospital and community nurses in Brunei. Methods: A cross-sectional survey on nurses from public hospitals and community health centres from all four districts in the country. The questionnaire included Perceived Stress Scale to measure stress levels, the brief Big Five Inventory to identify personality, the Morningness-Eveningness Questionnaire to identify chronotype, and the Sakata Eating Behaviour Questionnaire to identify eating behaviour. Subgroup analysis and partial least squares structural equation modelling were applied. Results: The structural equation model revealed that personality trait (β = 0.482) is the most salient and strongest factor contributing to perceived stress, followed by chronotype profile (β = 0.45), accounting for 71.4% of the variance explained for perceived stress. Whereas perceived stress (β = 0.719) is a factor affecting eating behaviour, which accounts for 51.6% of the variance explained for eating behaviour. Conclusions: This study revealed that neuroticism and evening chronotype are significant stress predictors. Stress affects eating habits, with stressed nurses showing poor eating patterns. Older and single nurses report higher stress.
