Research & Publications

From the start, 22 Jumps has been built on a simple belief: the fight against veteran suicide has to be driven by evidence. We fund research, and we let it guide the work.

A note from our CEO

Why research sits at the center of 22 Jumps.

At 22 Jumps, the BASE jumping and the science are not separate. Every event, every retreat, and every dollar serves one question: how do we keep veterans and first responders alive? Research is how we answer it honestly.

We contribute to research by funding the studies and partnerships digging into traumatic brain injury, the injury behind so many suicides. The research drives what we do, so our programs stand on evidence, not just good intentions.

What you’ll find below is part of that commitment, with more on the way.

What we’re building

Research initiatives.

Our research is organized around detecting, treating, and living well after traumatic brain injury, and it’s carried out with leading academic partners.

Flagship program

Kiernan Wimmer TBI Innovation Initiative

Funds the science behind better detection, treatment, and therapeutics for traumatic brain injury – the injury behind so many suicides.

Academic partners

University of Utah Health & Mount Sinai

University of Utah HealthBrain Injury Research Center of Mount Sinai

Community-informed research with the Brain Injury Research Center of Mount Sinai and University of Utah Health’s TBI & Concussion Center – where veterans help shape the science, not just receive it.

Federal research

DoD-funded TBI research projects

22 Jumps consults on multiple research efforts and co-leads advisory boards for U.S. Department of Defense–funded traumatic brain injury initiatives.

What the research says

The injury and the risk are linked.

Findings from national surveillance and peer-reviewed cohorts. Each describes an association, not a cause, and each links to the original paper.

94%

Veterans with a diagnosed TBI are at higher risk of suicide than veterans without a TBI. 1

2.45×

Veterans with moderate or severe TBI are at 2.45 times higher risk of dying by suicide than veterans without TBI. 2

1.90×

People with a medical contact for TBI had 1.90 times the suicide rate of people without TBI. 3

More TBIs,
higher risk

Suicide rates rose with repeated TBI contacts: 34.3 per 100,000 person-years after one, 59.8 after two, and 90.6 after three or more, versus 19.9 with none. 3
