Assessment of subjective stress in video display terminal workers

Stress assessment in the workplace has been focused on its environmental, psychological and biological aspects. We carried out an evaluation of the subjective components of stress in a working population of 60 subjects employed in a large Public Service, 30 Video Display Terminal (VDT) workers (15 men and 15 woman) and 30 office-workers not assigned to VDT (15 men and 15 woman), by using the "Rapid Stress Assessment Scale": a short questionnaire of easy administration in work environment. VDT workers of both sexes showed higher total stress score vs. office workers (respectively p<0.05, p<0.05). Gender differences were present: female VDT workers showed higher scores of clusters anxiety (p<0.001) and aggressiveness (p<0.05); male VDT workers' score were significantly higher in somatization (p<0.05) and aggressiveness cluster. Our results showed that in VDT workers are experienced greater subjective response to stress than "office workers" and confirm the gender differences in stress experiencing.
