Situation awareness may be used to operationalize nursing students' clinical judgment of patient deterioration simulation scenarios.

To develop and test an instrument to measure bachelor-level nursing students' situation awareness in a patient deterioration simulation scenario, using the Situation Awareness Global Assessment Technique (SAGAT).

Instrument development and validation.

A faculty of nursing of a French-Canadian university.

15 critical care experts and 234 bachelor-level nursing students from a critical care course.

The queries were developed from evidence and guidelines regarding nurses' assessment and response to patient deterioration and an inventory of nursing diagnosis. After expert content validation, the instrument was administered to three cohorts of nursing students in a high-fidelity simulation with a scenario of hypovolemic hemorrhagic shock. Difficulty, discrimination, and fidelity indices were computed. The impact of the instrument on student's performance was assessed with a post-simulation survey.

The instrument comprised 31 queries, which obtained high content validity indices. Most showed satisfying difficulty, discrimination, and fidelity properties. Inadequate properties of the queries may be explained by the content of the simulation scenario, the assessment practices of nursing students, and their reliance on medical assistance. Students perceived that completing the instrument helped them realize what they forgot to assess in the simulation.

This instrument appears as a promising research tool, although it still needs to be tested with other populations and in other patient deterioration simulation scenarios.
