# Neurocognitive markers of short-term risk for suicidal behavior in high-risk Veterans > **NIH VA I01** · VA NEW JERSEY HEALTH CARE SYSTEM · 2021 · — ## Abstract Project Summary/Abstract Given the high rates of Veteran suicide each year, suicide prevention has become a VHA strategic priority. While progress has been made in screening Veterans for suicide risk, high rates of false positives remain a challenge, potentially diverting clinical resources away from those Veterans who need them most. Innovative new approaches to assess suicide risk are needed, that accurately identify short-term (e.g. coming weeks) risk of suicidal behavior, and that are based on objective markers rather than relying primarily on self- report. Recent work has identified several cognitive domains, including impulse control and inhibition, increased distractibility, implicit semantic content, and processing of rewards/punishments, that may all be altered in suicidal individuals. The current project will use a battery of computer-based tests to assess these cognitive domains, followed by computational modeling to extract additional meta-variables representing latent cognitive processes, to prospectively predict short-term risk of suicidal behavior in high-risk Veterans. Veterans will be recruited from acute in-patient psychiatric units following a suicidal event, and tested at 3-month intervals for a year; we will also record suicidal behavior (SB), defined as an actual, interrupted, or aborted attempt or a behavior preparatory to suicide. In Aim 1, we will use neurocognitive task scores collected shortly before the SB, to determine which tasks (and therefore, alterations in which cognitive domains) can prospectively predict short-term risk of SB (within the next 3 months). In Aim 2, we will conduct computational modeling on the behavioral data, to extract additional meta-variables, describing latent cognitive processes such as response caution (impulsivity); subjective value of rewarding, punishing, and neutral feedback; perseveration; and tendency to explore new responses, to determine which of these meta-variables can prospectively predict SB. In Aim 3, we will combine these neurocognitive task scores and meta-variables, along with "standard" indicators of suicide risk such as demographic, self-report, and clinical assessment, in a statistical prediction model, to determine whether inclusion of these cognitive variables and meta-variables can significantly improve prediction of short-term risk for SB in this high-risk Veteran sample. The results of this study will provide much-needed information to improve identification of Veterans likely to make a suicide attempt in the upcoming weeks, so that clinical resources can be targeted to help them. The computer-based neurocognitive tests represent relatively objective behavioral markers that could be deployed fairly simply in a clinical setting or even via telehealth. Additionally, our focus on underlying cognitive processes, as modifiable factors, will improve the ability to optimize intervention by suggesting specific therapeutic approaches based on an individual Veteran's cogni... ## Key facts - **NIH application ID:** 9840829 - **Project number:** 5I01CX001826-02 - **Recipient organization:** VA NEW JERSEY HEALTH CARE SYSTEM - **Principal Investigator:** CATHERINE E MYERS - **Activity code:** I01 (R01, R21, SBIR, etc.) - **Funding institute:** VA - **Fiscal year:** 2021 - **Award amount:** — - **Award type:** 5 - **Project period:** 2019-01-01 → 2022-12-31 ## Primary source NIH RePORTER: https://reporter.nih.gov/project-details/9840829 ## Citation > US National Institutes of Health, RePORTER application 9840829, Neurocognitive markers of short-term risk for suicidal behavior in high-risk Veterans (5I01CX001826-02).
