Objectives: to determine the profile of psychosocial risks in workers at the Intensive Care Unit (ICU) according to occupational categories. Material and Methods: non-experimental study, quantitative, correlational-transversal.An analysis of variance of repeated measures (MANOVA) added to subsequent contrasts was used. 354 workers were censed considering four occupational categories: medics (n=55), nurses (n=111), nursing technicians (n=145) and service assistants (n=43). Along the whole research, international bioethical principles were contemplated. Results: the profile of psychosocial risks of the medics has significant differences with the other work groups (p≤0.05), because a higher level of psychosocial risk is perceived due to Psychological demands, but lower exposure to risks in Compensations and Double Presence are perceived. Conclusions: the profile of risks by work groups shows meaningful differences between perceptions of the workers. It allows to affirm that the interventions to prevent or intercede the psychosocial risks must be done in different ways in each category.
