title: [Discriminating capacity of the MASI-R questionnaire in the perception of work-stress].
abstract: BACKGROUND
  Workplace mobbing represents a severe type of occupational stress. The aim of this study is to evaluate the discriminant validity of the Maugeri Stress Index-Revised questionnaire (MASI-R) for the perceived work stress assessment.
  
  
  METHODS
  A total of 105 patients were enrolled at the Occupational Medicine Uinit of our Institute for mobbing-related issues; they were compared to a control group matched for age, sex and professional category. Work stress perception was assessed in both samples using the self-report questionnaire MASI-R, which is the Maugeri Stress Index short form.
  
  
  RESULTS
  Workers who perceived exposure to mobbing scored significantly lower compared to the control group in the four MASI-R scales (p < 0.001) and in the two visual analogue scales measuring job satisfaction (p < 0.001) and life satisfaction (p < 0.001). Further analyses have identified the items which significant discriminate between the two groups of workers.
  
  
  CONCLUSIONS
  These findings show a good discriminant validity of the MASI-R questionnaire: workers who perceived exposure to workplace mobbing reveal higher work stress levels compared to the control group in all aspects measured.
