Does prior exposure to clinical critical events influence stress reactions to simulation session in nursing students: A case-control study.

Background: Simulation is a pedagogical method known to be a generator of stress, that could be influenced by previous stressful experiences.

Objectives: The purpose of this study was to determine the impact of previous experience with a clinical critical event on the stress experienced by nursing students during simulation session of critical events, and on the stress experienced during clinical critical events subsequent to the training.

Design: Observational case-control study.
