Abstract

Law enforcement officers are routinely exposed to traumatic incidents that can lead to psychological distress, including posttraumatic stress disorder (PTSD). However, emerging literature highlights the potential for posttraumatic growth (PTG), a positive psychological change following adversity. This study examined the prevalence and predictors of PTG in a sample of 33 police officers from a Midwestern department. Using validated self-report measures, the study assessed the role of trauma exposure, cognitive restructuring of core beliefs, and perceived organizational culture, particularly supervisor support. Results indicated that both internal (core belief reflection) and external (supervisory support) factors significantly predicted PTG. Additionally, involvement in a shooting accounted for a unique portion of variance in PTG outcomes. These findings underscore the importance of supportive leadership and reflective processing in fostering resilience among officers, emphasizing trauma-informed leadership is not just a supportive resource, but a mechanism for transformation. By identifying key mechanisms of growth, this study informs strength-based interventions and policy recommendations aimed at enhancing officer wellness and psychological recovery.
