Initial Reliability and Validity of the Ohio State University TBI Identification Method

Objectives Evaluate the psychometric properties of indices of a lifetime history of traumatic brain injury (TBI). Participants Convenience samples recruited from 2 treatment programs for persons with substance use disorders: N = 119 (study 1) and N = 103 (study 2) Design Test interrater reliability (study 1) and predictive validity (Study 2). Measures Summary indices of the number, severity, timing, and effects of lifetime TBIs calculated from data elicited via a structured interview. Results Interrater reliability was high. Factor analysis showed indices could be characterized by severity weighted counts of the number of injuries, both lifetime and in childhood, number of symptoms persisting, worst injury,…
