Abstract:

Study investigated the relationships among substance misuse, depression, employment, and suicidal ideation (SI) following moderate-to-severe traumatic brain injury (TBI). Participants were 1,377 individuals with moderate-to-severe TBI enrolled in both the National Trauma Data Bank and the Traumatic Brain Injury Model Systems National Database, aged 18 to 59 years, with SI data available at year 1 or year 2 post injury. Self-reported SI was the primary outcome, with self-reported employment, substance misuse, and depression as secondary outcomes at years 1 and 2. Cross-lagged structural equation modeling analysis showed that year-1 unemployment and substance misuse were associated with a higher prevalence of year-1 depression. Depression was associated with concurrent SI at years 1 and 2. Older adults and women had a greater likelihood of year-1 depression. More severe overall injury (injury severity score) was associated with a greater likelihood of year-1 SI, and year-1 SI was associated with a greater likelihood of year-2 SI. Understanding and mitigating these risk factors are crucial for effectively managing post-TBI SI to prevent postinjury suicide.
