Psychological well-being and psychosocial work environment characteristics among emergency medical and nursing staff

The aim of this study was to determine if the effect of psychosocial work environment on psychological well-being was different for doctors and nurses who work in emergency departments in Spain. A cross-sectional survey was carried out among 945 emergency doctors and nurses staff from Spain. The outcome variable was the psychological well-being measured by two dimensions of SF-36 Health Survey (SF-36) (mental health, vitality) and one dimension of Maslach's Burnout Inventory (emotional exhaustion). The explanatory variable was the psychosocial work environment evaluated according to Karasek and Johnson's demand-control model that includes the dimensions of psychological demands, job control, supervisor social support and co-workers' social support. The adjusted odds ratios and their 95 per cent confidence intervals were calculated by logistic regression. The prevalence of low vitality, bad mental health and high emotional exhaustion was higher among doctors than nurses. Exposure to high psychological demands increased the probability of low vitality, bad mental health and high emotional exhaustion among doctors and nurses. Low job control and low co-workers' social support at work were associated with poor psychological well-being only among doctors. Low job supervisors' social support increased the risk of bad mental health among doctors and of high emotional exhaustion among nurses. There is a different effect of psychosocial work environment on psychological well-being between doctors and nurses. Copyright (c) 2007 John Wiley & Sons, Ltd.
