| Abstract: | Traumatic brain injury (TBI) is associated with suicidal behavior among veterans, and gender differences in the strength of associations may exist. Almost all research has been limited to Veterans Health Administration (VHA) patients, and it is unclear if findings generalize to veterans who do not use VHA services. We examined gender‐ and VHA‐user‐specific associations between TBI related to deployment and postdeployment suicidal ideation in a U.S. national sample of 1,041 female and 880 male Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans. Path analysis was used to estimate TBI and suicidal ideation association, and examine PTSD and depression symptomatology in these associations. TBI was associated with suicidal ideation among male VHA users, OR = 3.64, 95% CI [2.21, 6.01]; and male and female nonusers, OR = 2.24, 95% CI [1.14, 4.44] and OR = 2.65, 95% CI [1.26, 5.58], respectively, in unadjusted analyses. This association was explained by depression symptoms among male and female nonusers. Among male VHA users an association between TBI and suicidal ideation remained when accounting for depression symptoms, OR = 2.50, 95% CI [1.33, 4.71]. Our findings offered evidence of an association between TBI and suicidal ideation among male OEF/OIF VHA users. |
