Reliability and Predictive Validity of the Ohio State University TBI Identification Method With Prisoners
ABSTRACT Evaluate the psychometric properties of indices of lifetime exposure to traumatic brain injury (TBI) among prisoners.
Convenience samples recruited from male (N = 105) and female (N = 105) state prison facilities.
Assess test/retest reliability and criterion-related validity.
Summary indices of the number, severity, timing, and effects of lifetime exposure to TBI calculated from data elicited via a structured interview.
Test/retest reliability ranged from acceptable to high. Factor analysis showed that indices of lifetime exposure could be characterized by (1) age of onset (especially childhood onset), (2) combinations of number and likely severity of injuries, and (3) number of symptoms and functional effects. Age at injury, number of TBIs with loss of consciousness, and symptoms persisting contributed independently to the prediction of common cognitive and behavioral consequences of TBI.
These results provide further support for the reliability and validity of summary indices of lifetime exposure to TBI when elicited via a structured interview.

- "to α = .93 (Corrigan & Bogner, 2007), and test–retest reliability adequate with α > .60 (Bogner & Corrigan, 2009). To assess behavioral outcomes, the Adult's Self Report (ASR; Achenbach, Bernstein, & Dumenci, 2005) was used, which measures adaptive functioning in individuals aged 18–59 years. "
ABSTRACT: While the presence of externalizing behavioral problems following traumatic brain injury (TBI) has been well established in the literature, less is known regarding internalizing disorders, and more specifically anxiety disorders, in such a population. This study explored the presence, rate, and incidence of internalizing behavior problems, including anxiety, depression, somatic complaints, avoidant personality symptomatology, and overall internalizing behavior problems in university students aged 18-25 years. A convenience sample of 247 university students (197 non-TBI, 47 mild TBI, 2 moderate TBI, 1 severe TBI) aged 18-25 years was utilized. Participants completed a self-report measure on behavioral functioning, the Adult Self Report (ASR), to identify internalizing behaviors, and a questionnaire to identify TBI history. Raw scores of behavior indicated that participants with a history of childhood TBI reported significantly higher levels of withdrawal, somatic complaints, and internalizing behavioral problems than the non-TBI participants. When analyzing standardized T-scores for borderline and clinically elevated ASR syndromes and Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented scales, individuals in the TBI group were significantly more likely to have higher rates of borderline anxiety, somatic complaints, avoidant personality problems, and overall internalizing disorders, and clinically elevated somatic complaints. Adults with a history of childhood TBI were also significantly more likely to report at least 1 or more DSM disorders. These results clearly suggest that individuals with a childhood history of TBI are at a heightened risk for a range of internalizing disorders in early adulthood, which is particularly troubling in a university sample pursuing tertiary education.Journal of Clinical and Experimental Neuropsychology 09/2015; 37(7):776-84.

ABSTRACT: To describe the most recent estimates of the incidence and prevalence of traumatic brain injury (TBI) and review current issues related to measurement and use of these data. State of the science literature for the United States and abroad was analyzed and issues were identified for (1) incidence of TBI, (2) prevalence of lifetime history of TBI, and (3) incidence and prevalence of disability associated with TBI. The most recent estimates indicate that each year 235 000 Americans are hospitalized for nonfatal TBI, 1.1 million are treated in emergency departments, and 50 000 die. The northern Finland birth cohort found that 3.8% of the population had experienced at least 1 hospitalization due to TBI by 35 years of age. The Christchurch New Zealand birth cohort found that by 25 years of age 31.6% of the population had experienced at least 1 TBI, requiring medical attention (hospitalization, emergency department, or physician office). An estimated 43.3% of Americans have residual disability 1 year after hospitalization with TBI. [corrected] The most recent estimate of the prevalence of US civilian residents living with disability following hospitalization with TBI is 3.2 million. Estimates of the incidence and prevalence of TBI are based on varying sources of data, methods of calculation, and assumptions. Informed users should be cognizant of the limitations of these estimates when determining their applicability.The Journal of head trauma rehabilitation 03/2010; 25(2):72-80.

ABSTRACT: Explore the incidence of traumatic brain injury (TBI) in veterans seeking outpatient substance abuse treatment and the association between TBI and psychiatric diagnoses. The Ohio State University TBI identification method (OSU TBI-ID) was administered to veterans with positive TBI-4 screens; substance-related and psychiatric diagnoses were extracted from the medical record. : Over an 18-month period, 247 veterans completed the TBI-4. Of the 136 who screened positive, 70 were administered the OSU TBI-ID. On the basis of the TBI-4, 55% (95% CI: 49%-61%) of veterans screened positive for a history of TBI. The OSU TBI-ID was used to confirm screening results. Those who completed the OSU TBI-ID sustained an average of 3.4 lifetime TBIs. For each additional TBI sustained, after initial injury, there was an estimated 9% increase in the number of psychiatric diagnoses documented (99% CI: 1%-17%). For each additional documented psychiatric diagnosis, there was an estimated increase of 11% in the number of injuries sustained (99% CI: 1%-22%). Also, 54% (38/70) had a positive history of TBI prior to adulthood. These results emphasize the need for TBI screening in this vulnerable population, as well as the importance of increasing brain injury awareness among those abusing substances and their care providers. These findings also highlight the need for specialized services for those with TBI and co-occurring substance misuse aimed at decreased future TBIs or negative psychiatric outcomes or both. Further study is needed to clarify best practices.The Journal of head trauma rehabilitation 04/2010; 25(6):470-9. DOI:10.1097/HTR.0b013e3181d717a7 · 2.92 Impact Factor
