Abstract

This study evaluated whether a history of traumatic brain injury (TBI) was associated with increased risk for recent suicidal ideation (SI) after accounting for demographics, depression, posttraumatic stress disorder (PTSD), and sleep quality. In terms of increased risk, we hypothesized that a history of lifetime TBI would be associated with increased recent SI when compared with no history of TBI; multiple injuries were also evaluated. The sample included Iraq and Afghanistan war-era veterans (n = 838) who served in the United States military since 9/2001 and completed a structured TBI interview. Approximately 50% reported a lifetime history of at least 1 TBI, and 17.9% met criteria for current major depressive disorder (MDD). SI over the past week per the Beck Scale for Suicide Ideation was the primary outcome. Demographics, current MDD and posttraumatic stress disorder (PTSD) per Structured Clinical Interview of DSM-IV Axis I Disorders, sleep quality per Pittsburgh Sleep Quality Index, and TBI history per structured interview were included in all statistical models. Current depression and poor sleep quality were consistently associated with recent SI. A history of any TBI history across the life span was not associated with increased recent SI (OR = 1.35, 95% CI [0.83, 2.19]). However, a history of multiple TBIs compared with no history of TBI was associated with increased recent SI (OR = 1.76, 95% CI [1.01, 3.06]). Results support the assertion than an accumulation of injuries amplifies risk. Severity of injury and deployment injuries were not significant factors. Among those with a history of 1 TBI, sleep, and depression, which may also be injury sequelae, may be salient treatment targets. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
