Situation awareness as described by Endsley (2000): perception, comprehension, and projection of signs of deterioration.
This is an instrument to measure situation awareness in nurses participating in a patient deterioration simulation scenario. It measures nurses' perception of quantifiable signs of deterioration (e.g., vital signs, level of consciousness) and less quantifiable signs of deterioration (e.g., breath sounds, agitation, new pain). It also measures nurses' comprehension of the meaning of these signs and their projection of their status in the near future. The instrument has been used to operationalize the concept of clinical judgment in a RCT (publication under review).
- Manikin (high sophistication)
- Manikin (mid/low sophistication)
- Standardized/simulated patients or real patients
In a previous validation study in a scenario of hemorraghe (Lavoie, Cossette, & Pepin, 2016), all items obtained high content validity index and the instrument obtained a content validity index of 0.97. Most items showed proper psychometrics value (difficulty, discrimination, and reliability indices). Cronbach's alpha reached 0.64. The instrument should be used to compare nurses or nursing students' situation awareness in the same scenario. Comparison between different scenarios showed that the psychometrics properties of the instrument varied from one scenario to another.
