Psychiatric diagnoses, mental health utilization, high-risk behaviors, and self-directed violence among veterans with comorbid history of traumatic brain injury and substance use disorders

摘要

OBJECTIVES:: To describe various characteristics of veterans with co-occurring histories of traumatic brain injury (TBI) and substance use disorder (SUD) for purposes of hypothesis generation. STUDY DESIGN:: Archival data collected over a period of 4 years. PARTICIPANTS:: Sixty-five veterans across eras of service with confirmed histories of TBI and SUD. METHODS:: Demographic and TBI information were obtained from an archival clinical database. Electronic medical records were reviewed for mental health utilization, psychiatric diagnoses, self-directed violence, and risk-taking behaviors. RESULTS:: In addition to a SUD, veterans were reported to have an average of 3 additional psychiatric diagnoses and a median of 3 TBIs per person. All utilized various mental health services in addition to substance use treatment. Individuals were found to have engaged in a variety of risky behaviors. There were significant associations between suicidal ideation and assaultive behaviors, as well as between suicide attempt and impulsivity. CONCLUSIONS:: This study describes a sample of veterans with co-occurring histories of TBI, SUD, risk-taking behaviors, and self-directed violence. More research is needed to examine these complex interrelationships and to identify specific risk factors for intervention/prevention strategies.
