Abstract:Preventing suicide among military veterans has been a high priority in the United States since the early 2000s. In 2022, suicide rates among veterans were 1.5 times greater than non-veterans. This rate has been lower for veterans in all but 2 of the past 14 years, with the exceptions being 2020 and 2021, which showed a slight increase. The collection of articles in this Research Topic showcases evidence of recent novel interventions and investigations advancing our understanding of preventing suicide among military veterans. These articles range from investigations illuminating suicide mechanisms through basic science and neuroscience, to research on interventions and an implementation trial, and studies focused on special populations at risk.
