The effect of mindfulness on the occupational stress of nurses in critical care units: a randomized clinical trial

Elevated occupational stress poses a significant challenge for nurses, especially those in critical care settings. Effectively managing this stress is crucial for both the well-being of nurses and the safety of patients. This study aimed to explore the effects of a mindfulness-based intervention on the occupational stress levels of nurses working in critical care units.

This randomized controlled trial involved a convenience sample of 68 nurses from critical care units. Participants were randomly assigned to either an intervention group (n = 34) or a control group (n = 34). The intervention group participated in eight 90-minute mindfulness sessions based on the Segal, Teasdale, and Williams model. The Occupational Stress Scale for Nurses was utilized to assess stress levels before and after the intervention.

Prior to the intervention, mean occupational stress scores were comparable between the intervention group (33.37 ± 7.43) and the control group (33.80 ± 7.71) (P = 0.761). Post-intervention, the intervention group exhibited a significantly lower mean score (24.79 ± 4.56) compared to the control group (33.19 ± 8.66) (P < 0.001). After the intervention, stress related to environmental/organizational factors and high workload considerably decreased (P < 0.001) within the intervention group. The reduction in occupational stress was substantial and clinically significant, as indicated by the Reliable Change Index.

Mindfulness interventions are effective in alleviating occupational stress among nurses in critical care units. This cost-effective and simple approach shows potential for reducing workplace stress. Further research is warranted to evaluate long-term effects and broader applications.
