Characteristics and Health Outcomes of Post-9/11 Caregivers of US Service Members and Veterans Following Traumatic Brain Injury

Health outcomes before and during the COVID-19 pandemic in caregivers of service members and veterans with traumatic brain injury

PURPOSE

To examine change in health-related quality of life (HRQOL) during the COVID-19 pandemic in caregivers of service members/veterans (SMVs) with traumatic brain injury (TBI), by comparing HRQOL during the first year of the pandemic to HRQOL 12 months pre-pandemic.

METHODS

Caregivers (N = 246) were classified into three COVID-19 Pandemic Impact groups based on impact ratings of the pandemic on HRQOL: No Impact (n = 50), Mild Impact (n = 117), and Moderate-Severe Impact (n = 79). Caregivers completed 19 measures across physical, social, caregiving, and economic HRQOL domains, and a measure of SMV Adjustment. T-scores were used to determine individual symptom trajectories for each measure as follows: Asymptomatic (pre + during < 60 T); Developed (pre < 60 + during ≥ 60 T); Improved (pre ≥ 60 T + during < 60 T); and Persistent (pre + during ≥ 60 T).

RESULTS

Using ANOVA, during the pandemic, the Moderate-Severe Impact group reported worse scores on 19 measures (d = 0.41-0.89) compared to the No Impact group and 18 measures (d = 0.31-0.62) compared to the Mild Impact group (d  = 0.31-0.38). The Mild Impact group reported worse scores on two measures compared to the No Impact group (d = 0.42-0.43). Using the entire sample, the majority of HRQOL measures were classified as Asymptomatic (47.2-94.7%), followed by Persistent (2.4-27.2%). Few were classified as Developed (0.4-12.6%) or Improved (2.4-13.8%). Using repeated measures ANOVA, no meaningful effects sizes were found for mean scores on all measures completed pre-pandemic compared to during the pandemic (d ≤ 0.17).

CONCLUSION

The vast majority of caregivers reported stability in HRQOL pre-pandemic compared to during the pandemic. The COVID-19 pandemic was not associated with a high prevalence of decline in caregiver HRQOL.

Caregiver sleep impairment and service member and veteran adjustment following traumatic brain injury is related to caregiver health-related quality of life

STUDY OBJECTIVES

To examine the relationship between caregiver sleep impairment and/or service member/veteran (SMV) adjustment post-traumatic brain injury, with caregiver health-related quality of life (HRQOL).

METHODS

Caregivers (n = 283) completed 18 measures of HRQOL, sleep impairment, and SMV adjustment. Caregivers were classified into 4 sleep impairment/SMV adjustment groups: 1) Good Sleep/Good Adjustment (n = 43), 2) Good Sleep/Poor Adjustment (n = 39), 3) Poor Sleep/Good Adjustment (n = 55), and 4) Poor Sleep/Poor Adjustment (n = 146).

RESULTS

The Poor Sleep/Poor Adjustment group reported significantly worse scores on most HRQOL measures and a higher prevalence of clinically elevated T-scores (≥ 60T) on the majority of comparisons compared to the other 3 groups. The Good Sleep/Poor Adjustment and Poor Sleep/Good Adjustment groups reported worse scores on the majority of the HRQOL measures and a higher prevalence of clinically elevated scores on 7 comparisons compared to the Good Sleep/Good Adjustment group. Fewer differences were found between the Good Sleep/Poor Adjustment and Poor Sleep/Good Adjustment groups. The Poor Sleep/Poor Adjustment group reported a higher prevalence of severe ratings for SMV Irritability, Anger, and Aggression compared to the Good Sleep/Poor Adjustment group.

CONCLUSIONS

While the presence of either caregiver sleep impairment or poor SMV adjustment singularly was associated with worse caregiver HRQOL, the presence of both sleep impairment and poor SMV adjustment was associated with further impairment in HRQOL. Caregivers could benefit from sleep intervention. Treatment of SMVs neurobehavioral problems may improve the SMV's recovery and lessen sleep problems, distress, and burden among their caregivers.

The effect of war injury and combat deployment on military wives' mental health symptoms

BACKGROUND

Although much has been learned about the physical and psychological impacts of deployment and combat injury on military service members, less is known about the effects of these experiences on military spouses.

METHODS

The present study examined self-reported mental health symptoms (using the Brief Symptom Inventory [BSI]-18 and the posttraumatic stress disorder [PTSD] Checklist [PCL-C]) in wives of service members who were combat-injured (CI; n = 60); noninjured with cumulative deployment longer than 11 months (NI-High; n = 51); and noninjured with cumulativel deployment less than 11 months (NI-Low; n = 53).

RESULTS

36.7% and 11.7% of CI wives endorsed above threshold symptoms on the PCL-C and overall BSI-18, respectively. Multivariate linear regressions revealed that being a CI wife was associated with higher PCL-C, overall BSI-18, and BSI-18 anxiety subscale scores compared to NI-Low wives in models adjusted for individual and family characteristics, as well as prior trauma and childhood adversities. Compared with the NI-High group, the CI group was associated with higher overall BSI-18 scores.

CONCLUSIONS

While CI wives evidenced fewer mental symptoms than expected, these findings suggest a negative impact of service member's combat injury on wives' mental health above that attributable to deployment, highlighting the need for trauma-informed interventions designed to support the needs of military wives affected by combat injury.

Is Traumatic Brain Injury Severity in Service Members and Veterans Related to Health-Related Quality of Life in Their Caregivers?

OBJECTIVE

To examine the relationship between service member/veteran (SM/V) traumatic brain injury (TBI) severity with caregiver health-related quality of life (HRQOL).

SETTING

Military treatment facility.

PARTICIPANTS

Caregivers (N = 316) of SM/Vs following a TBI divided into 2 groups based on SM/V TBI severity: (1) caregivers of SM/Vs following an uncomplicated mild TBI (UnMTBI Caregiver group, n = 246), and (2) caregivers of SM//Vs following a complicated mild, moderate, severe, or penetrating TBI (STBI Caregiver group, n = 70). The STBI Caregiver group was further divided into 2 subgroups: Parent (n = 21) versus Intimate Partner (n = 49). The UnMTBI Caregiver group consisted of intimate partners.

DESIGN

Prospective cohort.

MAIN MEASURES

Caregivers completed 15 HRQOL measures.

RESULTS

Using analysis of variance and chi-square analysis, the UnMTBI Caregiver group reported worse scores on 12 HRQOL measures and more clinically elevated scores for 6 of 15 comparisons than the STBI Caregiver group. The UnMTBI Caregiver group also reported worse scores on 10 HRQOL measures than intimate partners in the STBI Caregiver group and 5 measures than parents in the STBI Caregiver group. Parents reported worse scores on 3 measures than intimate partners in the STBI Caregiver group. The UnMTBI Caregiver group reported more clinically elevated scores for 7 of 15 comparisons than intimate partners in the STBI Caregiver group.

CONCLUSION

Intimate partner caregivers of an SM/V following a remote uncomplicated MTBI reported worse HRQOL than intimate partners and parent caregivers of an SM/V following a more severe TBI, mostly likely due to SM/V physical and mental health comorbidities. Interventions that focus on the SM/V's TBI and other comorbidities, the caregiver's behavioral health problems, and the relationship and family factors that interact with each other will likely have the most success in improving individual and family outcomes for military families.

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 treatment 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 χ² 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 their caregivers.

Pain interference and health-related quality of life in caregivers of service members and veterans with traumatic brain injury and mental health comorbidity

PURPOSE

To examine (1) the relationship between caregiver pain interference with caregiver health-related quality of life (HRQOL), caregiver age, and service member/veteran (SMV) functional ability, and (2) change in caregiver pain interference longitudinally over 5 years.

METHOD

Participants were 347 caregivers of SMVs diagnosed with traumatic brain injury (TBI). Caregivers completed the SF-12v2 Health Survey Bodily Pain scale at an initial baseline evaluation and up to four annual follow-up evaluations. Caregivers were divided into three pain interference groups: High Pain Interference (n = 104), Neutral Pain Interference (n = 117), and Low Pain Interference (n = 126). Caregivers also completed 15 HRQOL measures and a measure of SMV functional ability.

RESULTS

The High Pain Interference group reported more clinically elevated scores on 13 measures compared to the Low Pain Interference group, and seven measures compared to the Neutral Pain Interference group. The Neutral Pain Interference group had more clinically elevated scores on three measures compared to the Low Pain Interference group. The High and Neutral Pain Interference groups were older than the Low Pain Interference group. Parent caregivers were older than intimate partner/sibling caregivers, but did not report worse pain interference. Caregiver age, and measures of Fatigue, Strain, Perceived Rejection, and Economic QOL were the strongest predictors of pain interference (p < .001), accounting for 28.2% of the variance. There was minimal change in Bodily Pain scores over five years. The interaction of time and age was not significant (X² = 2.7, p = .61).

CONCLUSION

It is important to examine pain in the context of HRQOL in caregivers, regardless of age.

Emotional Suppression and Hypervigilance in Military Caregivers: Relationship to Negative and Positive Affect

OBJECTIVE

To investigate the relationship of 2 health-related quality-of-life (QOL) item banks (Emotional Suppression and Caregiver Vigilance), developed for caregivers of service members/veterans with traumatic brain injury (TBI), to caregivers' positive and negative affect.

SETTING

Community.

PARTICIPANTS

One hundred sixty-five caregivers of service members/veterans with TBI.

DESIGN

Retrospective database analysis.

MAIN MEASURES

TBI-CareQOL Emotional Suppression; TBI-CareQOL Caregiver Vigilance; measures of negative (Patient-Reported Outcomes Measurement Information System [PROMIS] Depression, PROMIS Anger, TBI-CareQOL Caregiver-Specific Anxiety, National Institutes of Health Toolbox [NIHTB] Perceived Stress, GAD-7) and positive affect (Neuro-QOL Positive Affect and Well-being, NIHTB Self-efficacy, NIHTB General Life Satisfaction, Family Resilience Scale for Veterans, TBI-QOL Resilience).

RESULTS

When considered separately, linear regression showed that higher levels of Emotional Suppression and greater Caregiver Vigilance were individually associated with more negative affect and less positive affect. When considered together, the pattern of findings was generally consistent for both Emotional Suppression and Caregiver Vigilance with regard to negative affect and for Emotional Suppression with regard to positive affect. However, when considered together, Caregiver Vigilance was no longer related to positive affect.

CONCLUSIONS

Caregivers with high emotional suppression and/or vigilance are more likely to show emotional distress and less likely to have positive affect than caregivers with lower levels of emotional suppression and vigilance. A combination of education and individual counseling targeting coping with negative emotions and TBI-related problems may be beneficial.

TBI-CareQOL military health care frustration in caregivers of service members/veterans with traumatic brain injury

PURPOSE

Caregivers of service members/veterans (SMVs) encounter a number of barriers when navigating the military health care system. The purpose of this study was to develop a new measure to assess potential caregiver frustration with the systems of care and benefits in the United States Departments of Defense and Veterans Affairs.

METHOD

The TBI-CareQOL Military Health Care Frustration measure was developed using data from 317 caregivers of SMVs with TBI who completed an item pool comprised of 64 questions pertaining to anger or frustration with accessing military health care services.

RESULTS

Exploratory and confirmatory factor analyses supported the retention of 58 items. Constrained graded response model (GRM) overall fit and item fit analyses and differential item functioning investigations of age and education factors supported the retention of 43 items in the final measure. Expert review and GRM item calibration products were used to inform the selection of two 6-item static short forms (TBI-CareQOL Military Health Care Frustration-Self; TBI-CareQOL Military Health Care Frustration-Person with TBI) and to program the TBI-CareQOL Military Health Care Frustration computer adaptive test (CAT). Preliminary data supported the reliability (i.e., internal consistency and test-retest reliability) as well as the validity (i.e., convergent, discriminant, and known-groups) of the new measure.

CONCLUSIONS

The new TBI-CareQOL Military Health Care Frustration measure can be used to examine caregiver perceptions of and experience with the military health care system, to target improvements. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Caring for a service member or Veteran following traumatic brain injury influences caregiver mental health

This study examined factors related to poor mental health in caregivers assisting service members and Veterans (SMV) following traumatic brain injury (TBI). Participants were 201 military caregivers (96.0% female; Age: M = 39.2 years, SD = 10.2) of SMVs following a mild, moderate, severe, or penetrating TBI. The SF-36v2 Health Survey, Caregiver Appraisal Scale, Mayo-Portland Adaptability Inventory-4, and Caregiver Questionnaire were completed. Caregivers were divided into two mental health groups: Poor Mental Health (n = 108) and Good Mental Health (n = 93). Factors related to poor caregiver mental health were worse general health and stress appraisal, less personal time, unmet needs, and greater financial and employment strain. Factors also related to poor caregiver mental health included assisting a SMV who had sustained a mild TBI, did not have significant hospital care, had post-traumatic stress disorder, depression, and/or anxiety, was experiencing greater functional disability, and was experiencing physical expressions of irritability, anger, and aggression (all p's<.05; d =.29 to d =.64; OR = 1.911 to OR = 4.984). For many military caregivers, poor mental health may be related to the SMVs ongoing comorbid mental health symptoms and less so neurological impairment related to the brain injury. TBI treatment programs require a holistic approach that addresses the behavioral health concerns of both SMVs and their caregivers.

Establishing the Factor Structure of a Health-Related Quality of Life Measurement System for Caregivers of Persons Living With Traumatic Brain Injury

OBJECTIVES

To understand the factor structure of health-related quality of life specific to caregivers of people living with traumatic brain injury (TBI).

DESIGN

Prospective, cross-sectional data collection.

SETTING

Three TBI Model Systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility.

PARTICIPANTS

Caregivers (N=558) of people who have sustained a TBI (344 caregivers of civilians and 214 caregivers of service members or veterans; 85% women; 58% spouses; mean age, 46.12±14.07y) who have provided care for an average of 5.82±5.40 years.

INTERVENTIONS

Not applicable.

MAIN OUTCOMES MEASURES

The Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) measurement system including 10 Patient-Reported Outcomes Measurement Information System item banks (anger, anxiety, depression, social isolation, sleep disturbance, fatigue, ability to participate in social roles and activities, satisfaction with social roles and activities, emotional support, informational support) and 5 TBI-CareQOL banks (feelings of loss-self, feelings of loss-person with TBI, feeling trapped, caregiver-specific anxiety, caregiver strain).

RESULTS

Confirmatory factor analysis model fit indices were compared for 14 empirically derived and 5 theoretically derived models. Confirmatory factor analysis results indicated that the best model fit was for a 6-factor model with dimensions that included mental health, social support, social participation, social isolation, physical health, and caregiver emotion.

CONCLUSIONS

Results indicated that a 6-factor model provided the best model fit for health-related quality of life in caregivers of individuals with TBI. These results have utility for both research and clinical applications. Establishing the TBI-CareQOL's factor structure provides preliminary evidence of the measurement system's construct validity, helps inform the selection of measures for specific research or clinical interventions, and informs the development of composite scores.

Severity of military traumatic brain injury influences caregiver health-related quality of life

PURPOSE/OBJECTIVE

To examine the influence of traumatic brain injury (TBI) severity on the health-related quality of life of caregivers providing care to service members/veterans (SMV) following a TBI. Research Method/Design: Thirty caregivers (90.0% female; 70.0% spouse; age: M = 39.5 years, SD = 10.7) of SMVs who sustained a mild, moderate, severe, or penetrating TBI were recruited from Walter Reed National Military Medical Center and via community outreach to participate in one of six focus groups. Caregivers were classified into 3 TBI severity/caregiver groups: (a) moderate/severe/penetrating TBI caregiver group (n = 11); (b) mild TBI caregiver group (n = 10); and (c) equivocal TBI caregiver group (n = 9). Thematic analysis using a constant comparative approach was conducted with qualitative analysis software to identify common themes across the 3 severity/caregiver groups.

RESULTS

Eleven themes emerged: no time for self/needs last (83.3%), poor physical health (80.0%), increased stress/anxiety (76.7%), social isolation/loneliness (66.7%), lack of access to services (50.0%), impact on family life (46.7%), sleep issues (46.7%), finances/employment (36.7%), depression (30.0%), exhaustion (30.0%), and anger (16.7%). Exploratory pairwise comparisons revealed a higher proportion of the moderate/severe/penetrating TBI group endorsed 7 of the 11 themes (no time for self/needs last, increased stress/anxiety, impact on family life, sleep issues, finances/employment, exhaustion, anger, and increased stress/anxiety) compared with the other 2 groups.

CONCLUSIONS/IMPLICATIONS

It is important that caregivers of SMVs receive long-term support in their caregiving and parenting roles. Further work is required to understand the challenges caregivers experience in accessing services they need and how to effectively meet their needs across the care continuum.
