- Brief Summary
Post-traumatic stress disorder (PTSD) is a disabling anxiety disorder that may occur after witnessing a traumatic event, and that evokes a combination of intrusion and avoidance symptoms, negative alterations in cognitions and mood, and alterations in arousal and reactivity1.
The primary objective of this pilot randomized controlled trial is to estimate and compare the effects of the practice of Brazilian Jiu Jitsu (BJJ) vs. hatha yoga vs. a waitlist control condition in influencing symptoms of PTSD, related comorbidities, post-traumatic growth, and quality of life among U.S. service members/veterans with current symptoms of PTSD. In addition, objective measurements (comparisons) of stress and sleep quality will be made through the collection and evaluation of salivary alpha amylase, hair cortisol, and actigraphy, a non-invasive way to measure activity cycles.
- Detailed Description
The design is a three arm randomized controlled pilot trial comparing the effects of a 10-week BJJ program (n=10) and a 10-week hatha yoga program (n=10) vs. a 5-week waitlist control regimen (n=5). Subjects randomly assigned to the waitlist condition will be offered the choice of participating in the BJJ or yoga intervention after the 5-week waitlist period. By trial inclusion criteria, all subjects will be male U.S. service members or veterans who report significant symptoms of PTSD (as determined by the 20-item PTSD checklist (PCL-5) and supplemental measures. Assessments will occur pre-intervention, at the midpoint of the intervention (5 weeks), at the end of the assigned intervention period (10 weeks), and at 2-month follow-up for the BJJ and yoga arms of the trial. Study variables will consist of reliable and valid self-report measures of symptom status to be completed by all study participants. In addition, saliva samples will be collected before and after individual sessions of BJJ/Yoga at 3 timepoints: first session, mid-point session at 5 weeks, and final session at 10 weeks. The same measurement schedule will be used for collection of hair cortisol samples and actigraphy assessment of sleep quality captured from wearing a watch for a one-week period of time at baseline, 5-weeks, and 10-weeks. The waitlist control group will wear the actigraphy watch at baseline and 5 weeks.
The trial will estimate effect size of the 2 active treatment arms (BJJ, Yoga) compared to the waitlist condition, and similarly, examine whether the BJJ arm appears to be non-inferior to the Yoga arm of the trial. Whereas the trial, designed as a pilot, is not powered for formal hypothesis testing, estimates of effect size will be examined with respect to the following underlying hypotheses:
1. Both the BJJ and Hatha Yoga regimens will provide evidence suggestive of superiority compared to the waitlist control regimen with respect to the primary outcome of symptoms of PTSD, as well as secondary outcomes.
2. Results will provide evidence suggestive of non-inferiority of the BJJ regimen compared to Hatha Yoga with respect to the primary outcome of symptoms of PTSD, as well as secondary outcomes.
Analyses will inform the design of a future planned large clinical trial to determine the potential benefit of BJJ and/or Yoga in reducing symptoms of PTSD and related comorbidities.

- Primary Outcome Measures
Name Time Method Change in PTSD Checklist - 5 (PCL-5) score Change from pre-intervention to 2 months after completion of BJJ training There are 20 questions that inquire about the different symptoms that correspond to 4 different types of PTSD symptoms (intrusion, avoidances, negative affect and hyperarousal). Each item is scored on a 5-point Likert scale from 0 (hasn't bothered a person in the past 2 weeks) to 4 (bothers the person all the time). We used total score on this test.
- Secondary Outcome Measures
Name Time Method Change in score on the Pittsburgh Sleep Quality Index (PSQI) Change from pre-intervention to 2 months after completion of BJJ training This self-report scale measures quality and patterns of sleep in adults over the prior month. In the first four questions, the participants are asked to provide discrete answers about bedtime, how long it takes them to fall asleep, what time do they get up in the morning and how many hours they sleep. All remaining questions are scored on a 4-point Likert scale. Standard scoring protocol will be performed. Total score on the test can range from 0-21.
Change in Brief Symptom Inventory -18 (BSI-18) score Change from pre-intervention to 2 months after completion of BJJ training This scale is the shortened form of the Symptom Checklist 90-Revised (SCL-90-R). There are 18 items that address clinically relevant psychological symptoms in adolescents and adults that cover three factors - Somatization, Depression, and Anxiety - as well as a Global Severity Index. We used the Global Severity Score which is simply the summation of all the scales. The study subject is asked to score each item from 0 (not at all) to 4 (extremely) with respect to the last 7 days.
Change in Posttraumatic Growth Inventory-Short form (PTGI-SF) Change from pre-intervention to 2 months after completion of BJJ training This scale assesses positive changes that may follow traumatic events. It consists of 10 items scored from "0" to "5" with 0 representing "no experience of change as a result of my crisis" and 5 representing "experiencing the change to a very great degree." The score from each item is summed to give a total score.
Change in score on the Alcohol Use Disorder Identification Test (AUDIT) Change from pre-intervention to 2 months after completion of BJJ training This instrument assesses alcohol consumption, drinking behaviors, and alcohol-related problems. There are 10 questions that are scored with a Likert scale ranging from "0" (Never) to "4" (4 or more times a week). Scores are totaled over the 10 questions. Total score ranges from 0-40, a score of 8 or more indicating potentially harmful behavior.
Change in score on the Centers for Epidemiological Studies Depression Scale (CES-D) Change from pre-intervention to 2 months after completion of BJJ training The CES-D is a self-report scale that measures depressive symptomatology during the past week. There are 20 items and they are rated depending on whether the statement is worded positively or negatively. For positively worded questions, the scoring is:
* Most or all of the time (5-7 days) = 0
* Occasionally or a moderate amount of time (3-4 days) = 1
* Some or a little of the time (1-2 days) = 2
* Rarely or none of the time (less than 1 day) = 3.
For negatively worded questions, the scores are opposite:
* Most or all of the time (5-7 days) = 3
* Occasionally or a moderate amount of time (3-4 days) = 2
* Some or a little of the time (1-2 days) = 1
* Rarely or none of the time (less than 1 day) = 0
The scores on each item are simply added together. Total score can range from 0-60.Change in score on the Pain Outcomes Questionnaire - Short Form (POQ) Change from pre-intervention to 2 months after completion of BJJ training This instrument assesses specific aspects of pain on five basic categories that include Activities of Daily Living (ADL), Mobility, Negative Affect (NA), Vitality, and Fear. Each item is scored on a scale of 0-10 with higher scores representing increase severity. Total score was used.
Change in Use of Medications Change from pre-intervention to 2 months after completion of BJJ training This is a self-made form that asks study participants to disclose medications that they are using and if medication use changes over time and with BJJ training
