Grappling With Trauma: Brazilian Jiu-Jitsu for First Responders
(CAM-GRIP)
What this study is about
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.
View original scientific description
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.
Interventions
BEHAVIORAL
Brazilian Jiu-Jitsu Program
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.
Primary outcome measures
Change in Trauma Symptom Severity (PCL-5)
Time frame: 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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
