Study examined the prevalence of depression and suicidal behavior in a large cohort of patients who sustained moderate-to-severe traumatic brain injury (TBI). Data were obtained from patients who received acute care and comprehensive rehabilitation in a TBI Model Systems-designated brain injury inpatient rehabilitation program funded by the National Institute on Disability and Rehabilitation Research (NIDRR). Depression and suicidal ideation were measured with the Patient Health Questionnaire (PHQ-9). Self-reported suicide attempts during the past year were recorded at each follow-up examination, at 1, 2, 3, 10, 15 and 20 years post-injury. A total of 8,547 participants comprised the sample for analyses addressing suicide attempts. The results showed that throughout the 20 years of follow-up, rates of depression ranged from 24.8 to 28.1 percent, suicidal ideation ranged from 7.0 to 10.1 percent, and suicide attempts (past year) ranged from 0.8 to 1.7 percent. Participants who endorsed depression and/or suicidal behavior at year 1 demonstrated consistently elevated rates of depression and suicidal behavior 5 years after TBI. Findings suggest that compared to the general population, individuals with TBI are at greater risk for depression and suicidal behavior many years after TBI. The significant psychiatric symptoms evidenced by individuals with TBI highlight the need for routine screening and mental health treatment in this population.
