Brief summary
This study explores whether participating in an 8-week Brazilian Jiu-Jitsu (BJJ) program is linked to changes in trauma-related symptoms among first responders. Many first responders experience ongoing stress or exposure to traumatic events, and some prefer physical, movement-based activities rather than traditional clinical services to support their well-being. In this study, participants will attend BJJ classes one to two times per week for eight weeks. They will also complete short daily and weekly questionnaires about mood, stress, and well-being, write brief weekly reflections, and participate in a one-on-one interview after the program. The study aims to understand both symptom patterns and participants' personal experiences with emotional regulation and overall wellness during the program. This study does not provide mental health treatment and will not diagnose or treat PTSD. Instead, it examines whether BJJ, as a non-clinical physical activity, may offer supportive benefits for first responders.
Detailed description
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.
Interventions
Participants engage in an 8-week Brazilian Jiu-Jitsu (BJJ) program delivered in a community martial arts academy. The intervention consists of beginner-level, instructor-led classes that emphasize controlled movement, breath regulation, positional problem-solving, and partner-based training. All participants attend the same type of classes and may modify activities as needed for safety. The BJJ program is a non-clinical, movement-based activity intended to support somatic regulation, emotional regulation, and relational connection. Participants complete daily behavioral rating scales, weekly PTSD symptom measures (PCL-5), and weekly journal reflections throughout the intervention. The program is preceded by a baseline phase with no BJJ participation and followed by a 4-week post-intervention phase to observe maintenance or change in symptoms. No randomization or masking is used; all participants receive the same intervention.

Study design
Intervention model description
This study uses a single-group assignment in which all participants receive the same 8-week Brazilian Jiu-Jitsu (BJJ) program. The design follows a single-case research structure with repeated measurement across three phases: baseline, intervention, and follow-up. Each participant serves as their own unit of analysis, allowing the study to examine individual patterns of change in trauma-related symptoms over time. Daily behavioral ratings, weekly PTSD symptom measures, weekly journal reflections, and a post-program interview are used to capture both quantitative and qualitative outcomes. No randomization or control group is used, and the study does not provide clinical treatment. The model is intended to observe whether participation in a structured, movement-based program is associated with changes in emotional and somatic regulation among first responders.
Eligibility
Inclusion criteria
* Current first responders (law enforcement, fire fighters, EMS, dispatch) * Adults (18+) * Experiencing trauma-related stress * Able/willing to attend BJJ classes twice per week * Able/willing to complete daily and weekly measures * Located in Montgomery County or nearby areas
Exclusion criteria
* Individuals younger that 18 years of age * Individuals who cannot safely participate in physical activity * Individuals who cannot complete daily/weekly measures * Individuals who are not current first responders * Individuals who need a higher level of care
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Trauma Symptom Severity (PCL-5) | 15 Weeks: Baseline Phase (3 weeks), Intervention Phase (8 weeks), Follow-Up Phase (4 weeks) | Weekly trauma symptom severity will be measured using the PTSD Checklist for DSM-5 (PCL-5). Scores will be collected across three phases: baseline, 8-week Brazilian Jiu-Jitsu intervention, and 4-week follow-up. The measure will be used to observe individual patterns of change in trauma-related symptoms over time. Each participant serves as their own unit of analysis within a single-case research design. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Daily Behavioral Regulation Scores | 15 Weeks Total: Baseline Phase (3 weeks), Intervention Phase (8 weeks), Follow-Up Phase (4 weeks) | Daily behavioral functioning will be assessed using four single-item 0-10 rating scales measuring anger/irritability, behavioral avoidance, somatic regulation, and relational connection. Participants complete these ratings each day across all phases: baseline, 8-week Brazilian Jiu-Jitsu intervention, and 4-week follow-up. These scales capture fluctuations in behavioral and emotional regulation that may not be fully represented by weekly trauma-symptom scores. Each participant serves as their own unit of analysis within a single-case research design. |
