| Abstract: | The present article investigates the traumatic brain injury (TBI)-suicide link, assessing whether (a) TBI accounts for variance in suicide risk, and (b) the interpersonal-psychological theory of suicide can be applied to TBI status. Matched case-control procedures applied to archival college student health data identified TBI and non-TBI subsamples (84 total). Individuals with a TBI possessed higher suicide risk than those without. Even accounting for the relative influence of strong suicide risk factors (i.e., depression, perceived burdensomeness, thwarted belongingness, and acquired capability), TBI was robustly associated with suicide risk. TBI history would be valuable to ascertain in assessing suicide risk. |
