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.\n\nBrazilian 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.\n\nThis 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.\n\nThis 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\u002Firritability, 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.",[28],{"label":29,"type":30,"description":31,"interventionNames":32},"Brazilian Jiu-Jitsu Program","EXPERIMENTAL","Participants in this arm complete all phases of the study, including a baseline period, an 8-week Brazilian Jiu-Jitsu (BJJ) program, and a 4-week follow-up phase.

During the 8-week intervention phase, participants attend beginner-level BJJ classes at a community academy and continue completing daily and weekly measures, along with weekly journal reflections. After the intervention, participants enter a 4-week follow-up phase in which they discontinue BJJ training and continue completing daily and weekly assessments to evaluate maintenance or change in symptoms.
