Effects of a psychological first aid (PFA) based on the SIX Cs model on acute stress responses in a simulated emergency.

Objective: The SIX Cs model, a neuropsychological framework for psychological first aid, addresses acute stress responses that may lead to functional failure and heighten the risk for posttraumatic stress disorder. Unlike emotional interventions, this model prioritizes Cognitive Communication to diminish emotional overwhelm and bolster cognitive functioning. It introduces a Challenge for active engagement, Control for cognitive management of situations, Commitment from the helper to reduce loneliness, and Continuity to ensure narrative coherence.
