A cross-sectional population-based study on the association of personality traits with anxiety and psychological stress: Joint modeling of mixed outcomes using shared random effects approach
Work related stress and anxiety may have a profound effect on an individual's wellbeing. In the case of doctors this may also affect patient care. This study measured stress, anxiety, and job satisfaction and the influence of personality factors on these in a group of preregistration house officers in the north east of England. A total of 109 preregistration house officers anonymously completed a lifestyles questionnaire designed to measure self rated psychological stress, state anxiety, job satisfaction, and personality characteristics. Results showed that 37.5% of women and 24% of men preregistration house officers suffered from possible psychological stress. Altogether 38.9% of women and 5.4% of men were suffering from possible anxiety and 8.3% of women and 2.7% of men were suffering from possible depression. The mean (SD) job satisfaction scores were 83.8(17.4) (range 52-127; median 86.5) for men and 80.5(16.7) (range 41-114; median 81) for women. Altogether 30.6% of men and 41.7% of women reported to be dissatisfied with the organisational processes in their job. There were significant negative correlations between stress and job satisfaction scores (r = -0.508; p<0.0001) and between anxiety and job satisfaction scores (r = -0.421; p<0.0001), and significant positive associations between anxiety and stress scores (r = 0.593; p<0.0001). Stress, anxiety, and depression scores were significantly correlated with neuroticism scores in both men and women. The personality characteristic of neuroticism was a predisposing factor for stress and anxiety in the junior doctors which may be taken into consideration when offering support and counselling.
