Relationship Stability After Traumatic Brain Injury Among Veterans and Service Members: A VA TBI Model Systems Study

Objective: To explore stability of relationships and predictors of change in relationship status 2 years following TBI/polytrauma. Setting: Five Department of Veterans Affairs Polytrauma Rehabilitation Centers (VA PRCs). Participants: A total of 357 active duty service members and Veterans enrolled in the Veterans Affairs Polytrauma Rehabilitation Centers Traumatic Brain Injury Model Systems database with complete marital status information at 2 years postinjury. Design: Prospective, longitudinal, multisite. Main Measures: Relationship status change was defined as change in marital status (single/never married; married; divorced/separated) at 2-year follow-up, compared with status at enrollment. Results: At the time of enrollment, 134 participants (38%) were single/never married; 151 (42%) were married, and 72 (20%) were divorced/separated. Of those married at enrollment, 78% remained married at year 2 while 22% underwent negative change. Multivariable analyses revealed that age and education at the time of injury and mental health utilization prior to injury were significant predictors of relationship change. Among those who were single/divorced/separated at the time of enrollment, 87% remained so at year 2 while 13% underwent positive change. Injury during deployment significantly predicted positive relationship change. Conclusions: The unmalleable, preinjury characteristics identified may be used as potential triggers for education, prevention, surveillance, and couples therapy, if needed

Race/Ethnicity and Retention in Traumatic Brain Injury Outcomes Research: A Traumatic Brain Injury Model Systems National Database Study

Objective: To investigate the contribution of race/ethnicity to retention in traumatic brain injury (TBI) research at 1 to 2 years post-injury. Setting: Community. Participants: 5548 Whites, 1347 Blacks, and 790 Hispanics enrolled in the Traumatic Brain Injury Model Systems National Database with dates of injury between October 1, 2002 and March 31, 2013. Design: Retrospective database analysis. Main Measure: Retention, defined as completion of at least one question on the follow-up interview by the person with TBI or a proxy. Results: Retention rates 1-2 years post-TBI were significantly lower for Hispanic (85.2%) than for White (91.8%) or Black participants (90.5%) and depended significantly on history of problem drug or alcohol use. Other variables associated with low retention included older age, lower education, violent cause of injury, and discharge to an institution versus private residence. Conclusions: The findings emphasize the importance of investigating retention rates separately for Blacks and Hispanics rather than combining them or grouping either with other races or ethnicities. The results also suggest the need for implementing procedures to increase retention of Hispanics in longitudinal TBI researc

Assessing Negative Attributions After Brain Injury With the Ambiguous Intentions Hostility Questionnaire

OBJECTIVES: (1) To explore the construct validity of the Ambiguous Intentions Hostility Questionnaire (AIHQ) in participants with traumatic brain injury (TBI) (ie, confirm negative attributions are associated with anger and aggression); and (2) use the AIHQ to examine negative attribution differences between participants with and without TBI. SETTING: Two rehabilitation hospitals. PARTICIPANTS: Eighty-five adults with TBI and 86 healthy controls (HCs). DESIGN: Cross-sectional survey. MAIN MEASURES: The AIHQ, a measure of negative attributions (intent, hostility, and blame), anger, and aggressive responses to hypothetical scenarios. RESULTS: Attributions were significantly correlated with anticipated anger and aggressive responses to AIHQ scenarios. Compared with HCs, participants with TBI reported stronger negative attributions (P ≤ .001), anger (P = .021), and aggressive responses (P = .002) to the scenarios. CONCLUSION: Negative attributions were associated with anger and aggression responses, demonstrating construct validity of the AIHQ in the TBI population. Participants with TBI judged others' behaviors more severely than HCs, similar to prior research using a different attribution measure. The AIHQ has promise as a practical instrument for assessing negative attributions after TBI

Relationship Between Hispanic Nativity, Residential Environment, and Productive Activity Among Individuals With Traumatic Brain Injury: A TBI Model Systems Study

Objective: To examine the influence of nativity and residential characteristics on productive activity among Hispanics at 1 year after traumatic brain injury (TBI). Setting: Acute rehabilitation facilities and community follow-up. Participants: A total of 706 Hispanic individuals in the TBI Model Systems National Database. Design: Secondary data analysis from a multicenter longitudinal cohort study. Main Measures: Nativity (foreign born or US native), productive activity derived from interview questions regarding employment status, and other demographic information. Census data were extracted by zip code to represent residential characteristics of aggregate household income and proportion of foreign language speakers (FLS). Results: Among foreign-born individuals with TBI, those living in an area with a higher proportion of FLS were 2.8 times more likely to be productive than those living in areas with a lower proportion of FLS. Among individuals living in an area with a lower proportion of FLS, US-born Hispanics were 2.7 times more likely to be productive compared with Hispanic immigrants. Conclusion: The relationship between nativity and productive activity at 1 year post-TBI was moderated by the residential proportion of FLS. Findings underscore the importance of considering environmental factors when designing vocational rehabilitation interventions for Hispanics after TBI

Evaluating Negative Attributions in Persons With Brain Injury: A Comparison of 2 Measures

Objectives: To compare construct and predictive validity, readability, and time-to-administer of 2 negative attribution measures in participants with traumatic brain injury (TBI). Setting: Two TBI rehabilitation hospitals. Participants: Eighty-five adults with complicated mild to severe TBI. Main Measures: Negative attributions (intent, hostility, and blame) and anger responses to hypothetical scenarios were measured with the Epps scenarios and the Ambiguous Intention Hostility Questionnaire (AIHQ). Trait aggression was measured with the Buss-Perry Aggression Questionnaire (BPAQ). Results: Associations between attributions and anger responses (ie, construct validity) within each measure were significant (Epps: r = 0.61-0.74; AIHQ: r = 0.39-0.71); however, associations were stronger for Epps (Ps < .001). Receiver operating characteristics (ROC) revealed attributions from both measures predicted BPAQ scores (area under the ROC curves = 0.6-0.8); predictive validity did not statistically differ between the 2 measures. Both had comparable readability (fifth- to sixth-grade levels), but Epps required longer administration times. Conclusion: Negative attributions affect anger and aggression after TBI, making it important to identify suitable assessments for the TBI population. While psychometric properties of the AIHQ and Epps scenarios should be further explored, this study offers early support for the use of either instrument in persons with TBI. Advantages and disadvantages of the AIHQ and Epps scenarios are highlighted
