Aggression in Military Members With Mild Traumatic Brain Injury and Post-Traumatic Stress Disorder Is Associated With Intimate Partner Health-Related Quality of Life

Objective: We aimed to examine the relationship between service member/veteran (SMV) aggression and health-related quality of life (HRQOL) in their intimate partners.Methods: This prospective cohort study included 201 female intimate partner caregivers of post-9/11 male SMVs with a diagnosis of uncomplicated mild traumatic brain injury and post-traumatic stress disorder from a military treat-ment facility. Caregivers completed 17 HRQOL measures and rated the level the SMV experiences problems with verbal or physical expressions of irritability, anger, or aggression on the Mayo-Portland Adaptability Inventory, 4th edition. Caregivers were classified into three SMV Aggression groups: i) none or very mild (n = 53); ii) mild (n = 47); and iii) moderate or severe (n = 101). HRQOL scores were classified as clinically elevated using a cutoff of 60T or higher.Results: Using c2 analysis, the moderate or severe group had a significantly higher proportion of clinically elevated scores on 15 HRQOL measures compared with the none or very mild group, and six measures compared with the mild group. The mild group had higher scores on two measures compared with the none or very mild group. Using analysis of covariance (and controlling for caregiver strain), the moderate or severe group had significantly higher scores on 11 HRQOL measures compared with the none or very mild group, and two measures compared with the mild group. The mild group had higher scores on five measures compared with the none or very mild group.Conclusions: Many caregivers who report moderate to severe SMV aggression after a traumatic brain injury report poor HRQOL beyond the strain of care provision. Traumatic brain injury and post-traumatic stress disorder programs should screen for and treat SMV aggression and attend to the health needs of SMVs' caregivers.(c) 2022 Jacobs Institute of Women's Health, George Washington University.

Automated summary

This study aimed to examine the relationship between SMV aggression and HRQOL in intimate partners of post-9/11 male SMVs. The results showed that caregivers of SMVs with moderate to severe aggression reported poor HRQOL, suggesting the importance of screening and treating aggression in SMVs and addressing the health needs of their caregivers.
