Brazilian Jiu-Jitsu for Trauma and Stress Disorders
(CAM-GRIP Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
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.

Experimental Treatment
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 baseline phase, participants do not engage in BJJ and complete daily behavioral rating scales and weekly PTSD symptom measures to establish symptom patterns prior to the intervention. 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. All participants receive the same sequence of activities and assessments, and no randomization or comparison arm is used.
