Determining the Relationship of Situational Awareness, Cognitive Flexibility, and Fatigue with Perceived Stress among Nurses
This cross-sectional study of 103 nurses suggests that while situational awareness and cognitive flexibility are inversely associated with fatigue, which in turn is a significant predictor of perceived stress, the poor model fit and study limitations necessitate cautious interpretation of these protective and mediational relationships.

In the high-stakes environment of a hospital, a nurse's mind is constantly working. They must track multiple patients, remember complex medication schedules, and react instantly to sudden changes in a patient's condition. This mental workload relies on two specific cognitive skills. The first is the ability to stay aware of everything happening around you, to understand what those events mean, and to predict what might happen next. The second is the mental agility to shift gears quickly when a plan fails or a new demand arises, finding a different way to solve a problem without getting stuck. These skills are vital for safety, but they require energy. When that energy runs out, a state of exhaustion known as fatigue sets in. This fatigue is not just physical tiredness; it is a deep mental weariness that makes it harder to think clearly. When nurses are exhausted, the daily pressures of their job can feel overwhelming, leading to a sense of being stressed. Understanding how these mental skills, exhaustion, and stress connect is crucial for protecting the well-being of the people who care for the sick.
Researchers from three medical universities in Iran set out to map these connections among clinical nurses. They wanted to know if having strong situational awareness and mental flexibility could act as a shield against stress, or if these factors worked through a different path. To find out, they gathered a group of 103 nurses working in various hospital wards, from emergency rooms to intensive care units. The participants filled out detailed questionnaires about their ability to focus and adapt, how tired they felt, and how stressed they perceived their work to be. The study was conducted over a short period in the spring of 2026, capturing a snapshot of the nurses' experiences at that time.
The results revealed a clear pattern in how these factors interact. The data showed that nurses who reported higher levels of mental flexibility and better situational awareness tended to feel less fatigued. In other words, those who could adapt their thinking and stay alert to their surroundings were less likely to be worn down by their shifts. Fatigue, in turn, was strongly linked to stress. Nurses who felt more exhausted also reported feeling more stressed. However, when the researchers looked at all these factors together to see what directly caused stress, a surprising finding emerged. Mental flexibility and situational awareness did not directly lower stress scores when fatigue was taken into account. Instead, fatigue was the only factor that directly predicted how stressed a nurse felt. This suggests that the benefit of being mentally sharp and adaptable is that it helps prevent exhaustion, and it is the lack of exhaustion that keeps stress at bay.
The researchers tested a model where mental skills might indirectly reduce stress by lowering fatigue, but the statistical fit of this model was not perfect. The data did not align with the theoretical structure as neatly as hoped, indicating that while the relationships are real, the exact way they connect is complex and not fully settled. The study authors noted that because they looked at the data at a single point in time, they cannot prove that mental skills cause less fatigue, or that fatigue causes stress. It is also possible that other unmeasured factors influenced the results. Despite these limitations, the findings point to a specific target for improvement. Rather than trying to directly teach nurses how to feel less stressed, interventions might be more effective if they focus on reducing fatigue. By helping nurses maintain their energy and perhaps supporting their ability to stay alert and adaptable, hospitals may indirectly create a less stressful work environment. The study concludes that while being mentally flexible and aware is valuable, its power lies in its ability to keep fatigue at bay, which in turn protects nurses from the heavy weight of perceived stress.
