摘要:Literature has shown that sentinel events may be considered as markers for measuring work-related stress levels. This aspect has been recognized by the Italian legislation, which requires its recognition for the measurement of occupational stress. This study aims to understand the role of sentinel events in the measurement of work-related stress. Samples of 249 subjects were divided in two balanced and proportional categories (inside sentinel events and outside sentinel events). At the samples the Organizational and Psychosocial Risk Assessment (OPRA) questionnaire was administered. The tests T-student and ANOVA from the OPRA results didn’t show any statistically significant differences between the subjects belonging to the sentinel events and those not belonging.
