The Ripple Effect: Applying Positive Psychology Principles in Debriefing to Transform Team Culture.

Healthcare is a complex system filled with high-stress and high-stakes situations that can put workers at risk for burnout and prime negative patterns of thinking. When an individual's job entails constantly searching for problems or areas of improvement, as in medicine, they can become "stuck" in this paradigm, which may then spill over into social interactions and further compound negative workplace culture. Simulation programs can be effective levers for positive culture change, promoting a growth mindset, learning orientation, and culture of safety. The field of positive psychology can further enhance this by providing specific and explicit tools that help shift individual and team mindsets toward a more positive orientation attuned to what is working well and thereby promote cultures of well-being and resilience. The simulation's position as an organizational node, with influence that extends beyond the learning environment, makes it uniquely situated to ripple these positive effects through teams, professions, and departments. In this technical report, we explore how core tenets of positive psychology can be leveraged within healthcare settings, where they intersect with concepts already present in debriefing practices, and how to intentionally apply strategies that promote positive workplace culture and individual resiliency. Our goal is to provide a practical guide for integrating positive psychology into simulation and debriefing programs, with a focus on conceptual framing, pragmatic strategies, and implementation tools that support clinician well-being and foster culture change in healthcare.
