ABSTRACT
Objective: to investigate the levels of occupational stress among nurses working in
different healthcare services in Brazil. Method: this is a cross-sectional study with data
collected from 416 nurses between May 31, 2023, and January 31, 2024, through an online
questionnaire covering sociodemographic variables and the Work Stress Scale. Data
analysis was conducted using PSPP version 1.6.2-g78a33a. The Mann-Whitney U and
Kruskal-Wallis tests were applied. Results: the majority of nurses (61.5%) presented high
levels of occupational stress. The sub-dimensions “Autonomy and control” (2.92 ± 0.95),
“roles and work environment” (2.77 ± 1.01) and “growth and recognition” (2.76 ± 1.11) of
the Work Stress Scale showed the highest scores of stress. There was no significant
relationship between the nurses’ sociodemographic variables and their occupational stress
scores (p>0.05). Conclusion: structural and cultural changes are crucial for reducing the
level of occupational stress among nurses. The study emphasizes the key role of healthcare
administrators and nurse managers in promoting healthier and more collaborative work
environments through effective management and leadership.

RESUMO
Objetivo: investigar os níveis de estresse ocupacional entre enfermeiros que trabalham
em diferentes serviços de saúde do território brasileiro. Método: trata-se de um estudo
transversal, com dados coletados de 416 enfermeiros entre 31 de maio de 2023 e 31 de
janeiro de 2024 por meio de um questionário online. Um questionário sociodemográfico
e a Escala de Estresse no Trabalho foram utilizados. A análise dos dados foi realizada
utilizando o PSPP versão 1.6.2-g78a33a. Foram aplicados os testes de Mann-Whitney U e
Kruskal-Wallis. Resultados: a maioria dos enfermeiros (61,5%) apresentou níveis elevados
de estresse ocupacional. As sub-dimensões “autonomia e controle” (2.92 ± 0.95), “funções
e ambiente de trabalho” (2.77 ± 1.01) e “crescimento e reconhecimento” (2.76 ± 1.11)
da Escala de Estresse no Trabalho obtiveram as pontuações mais altas. Não foi encontrada
uma relação significativa entre as variáveis sociodemográficas dos enfermeiros e seus
níveis de estresse ocupacional (p>0.05). Conclusão: mudanças estruturais e culturais são
cruciais para reduzir o nível de estresse ocupacional entre os enfermeiros. O estudo
destaca o papel fundamental dos administradores de saúde e gestores de enfermagem na
promoção de ambientes de trabalho mais saudáveis e colaborativos através de uma gestão
e liderança eficazes.
