Objective: To investigate the psychometric properties of the Brief Symptom Inventory-18 (BSI-18) among persons with traumatic brain injury (TBI). Design: Inception cohort design with cross-sectional follow-up of 6 months to 15 years. Setting: Rehabilitation hospital. Participants: Adults (N=257) with moderate to severe TBI (81 inpatients and 176 follow-up participants, analyzed separately). Interventions: Not applicable. Main Outcome Measures: The BSI-18 is a brief screen of psychologic distress with a Global Severity Index (GSI), and 3 clinical subscales: somatization. anxiety, and depression. Results: Internal consistency of the GSI was high in both follow-up participants (alpha = .91) and inpatients (alpha = .84), whereas estimates for the somatization, anxiety, and depression subscales were more variable (alpha range, .61-.84). As Would be expected for a measure of affective state, retest reliability estimates were only moderate. The BSI-18 GSI correlated with multiple measures of psychosocial adjustment. After accounting for demographics, injury severity, inpatient functional status, years Since injury, and various psychosocial factors. the BSI-18 showed incremental validity in predicting concurrent functional, psychosocial, and psychologic status. Conclusions: The BSI-18 GSI had excellent reliability and validity among inpatients and follow-up participants. Modest reliability estimates may place an upper bound on the validity of the BSI-18 clinical subscales in inpatient TBI populations.
