Grappling With Trauma: Brazilian Jiu-Jitsu for First Responders (CAM-GRIP)

This study examines whether participation in an 8-week Brazilian Jiu-Jitsu (BJJ) program is associated with changes in trauma-related symptoms among first responders. First responders frequently experience repeated exposure to stressful or potentially traumatic events, yet many avoid traditional mental health services due to stigma, confidentiality concerns, and cultural expectations of emotional control. As a result, trauma-related symptoms often remain unaddressed. Some first responders prefer movement-based, non-clinical activities to support their well-being, making BJJ a culturally familiar and accessible option.

Brazilian Jiu-Jitsu is a structured grappling-based martial art that emphasizes controlled movement, breath regulation, problem-solving under pressure, and connection with training partners. Prior research with veterans and law enforcement officers suggests that BJJ may support emotional regulation, somatic awareness, and reductions in trauma-related distress. However, little research has examined BJJ as a complementary and alternative method (CAM) specifically for the broader first responder population.

This study uses a single-case research design (SCRD) to follow each participant over time. Participants will attend beginner-level BJJ classes for eight weeks and complete daily behavioral rating scales and weekly PTSD symptom measures (PCL-5). They will also complete a brief weekly journal entry and a post-program interview to describe their experiences with stress, mood, regulation, and connection throughout the intervention. This mixed-methods approach allows the study to examine both symptom patterns and participants' lived experiences.

This is not a clinical treatment study and does not diagnose or treat PTSD. The BJJ program is a non-clinical physical activity offered in a community gym setting. The study aims to understand whether participation in BJJ is associated with changes in trauma-related symptoms and related behavioral patterns such as anger/irritability, avoidance, somatic regulation, and relational connection. Findings may help identify culturally aligned, movement-based wellness options for first responders who may not engage in traditional mental health services.
