The International Performance Resilience and Efficiency Program (“iPREP”) trains Use-of-Force trainers and first responders on methods that improve mental preparedness and physical readiness in high-stress situations. It is an evidence-based training program that enhances use-of-force decision-making and resilient responses to stress, through psychological and physiological control techniques utilized before, during, and after (in recovery) critical incidents.
The program is designed for police, military, and can be adapted for any other first response team that provides safety and security.
Empirical research studies conducted on this training program demonstrate that iPREP improves use-of-force decisions and resilient responses to stressful critical incidents. Resilient responses include improved emotional and physical control as demonstrated by less negative emotion, and more adaptive heart rate reactivity and stress hormone profiles.
Improved mental and physical control during stress has direct implications for enhanced safety for officers and the communities they serve.
