Health-related quality of life in caregivers of individuals with traumatic brain injury: development of a conceptual model

A Directed Content Analysis for Greatest Problems Among People With and Without Traumatic Brain Injury

OBJECTIVE

To characterize the greatest problem or need among individuals with a history of traumatic brain injury (TBI), as compared with individuals with a history of other neurologic conditions, mental health conditions, and no history of neurologic or mental health conditions.

DESIGN

A directed content analysis of open-text responses to a single online survey question using a framework guided by the Mayo-Portland Adaptability Inventory-4.

SETTING

Community.

PARTICIPANTS

A total of 2861 community-dwelling adults (n=274 with TBI; n=289 with other neurologic conditions besides TBI; n=454 with mental health conditions but no neurologic conditions; and n=1844 controls).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Open-text responses to the survey prompt: "What was your greatest problem or need over the past 2 weeks?"

RESULTS

The Participation index comprised the greatest proportion of responses across all 4 participant groups. A quarter (25.4%) of controls reported None (no problem/need), whereas only 7.9%-10.7% of participants in all other groups reported None. Among all groups, individuals with TBI reported the greatest proportion of problems in the Adjustment and Ability indices. Among people with TBI, Money Management (19.7%), None (10.6%), and Anxiety (7.7%) were the 3 most frequently reported problems. Compared with individuals with mild TBI (mTBI), individuals with moderate-to-severe TBI (msTBI) reported a higher proportion of problems in the Ability and Adjustment indices. Among individuals with msTBI, the Adjustment index accounted for the greatest proportion of problems.

CONCLUSIONS

This study employed a person-centered approach to understanding the greatest needs among individuals with TBI. Qualitative differences were observed between individuals with and without TBI, between people with mTBI and msTBI, and across genders among people with TBI. These findings can help guide research and policy toward addressing challenges perceived as highly important by people living in the community with TBI.

The reliability and validity of the TBI-CareQOL system in four diverse caregiver groups

PURPOSE

Establishing the psychometric reliability and validity of new measures is an ongoing process. More work is needed in to confirm the clinical utility of the TBI-CareQOL measurement development system in both an independent cohort of caregivers of traumatic brain injury (TBI), as well as in additional caregiver groups.

METHODS

An independent cohort of caregivers of people with TBI (n = 139), as well as three new diverse caregiver cohorts (n = 19 caregivers of persons with spinal cord injury, n = 21 caregivers for persons with Huntington disease, and n = 30 caregivers for persons with cancer), completed 11 TBI-CareQOL measures (caregiver strain; caregiver-specific anxiety; anxiety; depression; anger; self-efficacy; positive affect and well-being; perceived stress; satisfaction with social roles and activities; fatigue; sleep-related impairment), as well as two additional measures to examine convergent and discriminant validity (PROMIS Global Health; the Caregiver Appraisal Scale).

RESULTS

Findings support the internal consistency reliability (all alphas > 0.70 with the vast majority being > 0.80 across the different cohorts) of the TBI-CareQOL measures. All measures were free of ceiling effects, and the vast majority were also free of floor effects. Convergent validity was supported by moderate to high correlations between the TBI-CareQOL and related measures, while discriminant validity was supported by low correlations between the TBI-CareQOL measures and unrelated constructs.

CONCLUSION

Findings indicate that the TBI-CareQOL measures have clinical utility in caregivers of people with TBI, as well as in other caregiver groups. As such, these measures should be considered as important outcome measures for clinical trials aiming to improve caregiver outcomes.

Investigating the Effectiveness of a Family Intervention after Acquired Brain or Spinal Cord Injury: A Randomized Controlled Trial

(1) Background: Acquired brain injury (ABI) or spinal cord injury (SCI) constitutes a severe life change for the entire family, often resulting in decreased quality of life (QoL) and increased caregiver burden. The objective of this study was to investigate the effectiveness of a family intervention in individuals with ABI or SCI and in their family members. (2) Methods: An RCT of a family intervention group (FIG) vs. a psychoeducational group (PEG) (ratio 1:1) was performed. The FIG received an eight-week manual-based family intervention, and the PEG received one psychoeducational session. Self-reported questionnaires on QoL with the Mental Component Summary (MCS) and on caregiver burden with the Caregiver Burden Scale (CBS) were the primary outcomes. The data analysis involved linear mixed-effects regression models. (3) Results: In total, 74 participants were allocated randomly to the FIG and 84 were allocated randomly to the PEG. The FIG had significantly larger improvements on the MCS and significantly larger reductions on the CBS at the two-month follow-up than participants in the PEG (mean differences of 5.64 points on the MCS and -0.26 points on the CBS). At the eight-month follow-up, the between-group difference remained significant (mean difference of 4.59 points) on the MCS, whereas that on the CBS was borderline significant (mean change of -0.14 points). (4) Conclusions: Family intervention was superior to psychoeducation, with larger improvements in QoL and larger reductions in caregiver burden.

An app-based just-in-time-adaptive self-management intervention for care partners: The CareQOL feasibility pilot study

PURPOSE/OBJECTIVE

The primary objective of this study was to establish the feasibility and acceptability of an intensive data collection protocol that involves the delivery of a personalized just-in-time adaptive intervention (JITAI) in three distinct groups of care partners (care partners of persons with spinal cord injury [SCI], Huntington's disease [HD], or hematopoietic cell transplantation [HCT]).

RESEARCH METHOD/DESIGN

Seventy care partners were enrolled in this study (n = 19 SCI; n = 21 HD, n = 30 HCT). This three-month (90 day) randomized control trial involved wearing a Fitbit to track sleep and steps, providing daily reports of health-related quality of life (HRQOL), and completing end of month HRQOL surveys. Care partners in the JITAI group also received personalized pushes (i.e., text-based phone notifications that include brief tips or suggestions for improving self-care). At the end of three-months, care partners in both groups completed a feasibility and acceptability questionnaire.

RESULTS

Most (98.6%) care partners completed the study, average compliance was 88% for daily HRQOL surveys, 96% for daily steps, and 85% for daily sleep (from wearing the Fitbit), and all monthly surveys were completed with the exception of one missed 3-month assessment. The acceptability of the protocol was high; ratings exceeded 80% agreement for the different elements of the study. Improvements were seen for the majority of the HRQOL measures. There was no evidence of measurement reactivity.

CONCLUSIONS/IMPLICATIONS

Findings provide strong support for the acceptability and feasibility of an intensive data collection protocol that involved the administration of a JITAI. Although this trial was not powered to establish efficacy, findings indicated improvements across a variety of different HRQOL measures (~1/3 of which were statistically significant).

Improving outcomes for care partners of persons with traumatic brain injury: Protocol for a randomized control trial of a just-in-time-adaptive self-management intervention

Informal family care partners of persons with traumatic brain injury (TBI) often experience intense stress resulting from their caregiver role. As such, there is a need for low burden, and easy to engage in interventions to improve health-related quality of life (HRQOL) for these care partners. This study is designed to evaluate the effectiveness of a personalized just-in-time adaptive intervention (JITAI) aimed at improving the HRQOL of care partners. Participants are randomized either to a control group, where they wear the Fitbit® and provide daily reports of HRQOL over a six-month (180 day) period (without the personalized feedback), or the JITAI group, where they wear the Fitbit®, provide daily reports of HRQOL and receive personalized self-management pushes for 6 months. 240 participants will be enrolled (n = 120 control group; n = 120 JITAI group). Outcomes are collected at baseline, 1-, 2-, 3-, 4-, 5- & 6-months, as well as 3- and 6-months post intervention. We hypothesize that the care partners who receive the intervention (JITAI group) will show improvements in caregiver strain (primary outcome) and mental health (depression and anxiety) after the 6-month (180 day) home monitoring period. Participant recruitment for this study started in November 2020. Data collection efforts should be completed by spring 2025; results are expected by winter 2025. At the conclusion of this randomized control trial, we will be able to identify care partners at greatest risk for negative physical and mental health outcomes, and will have demonstrated the efficacy of this JITAI intervention to improve HRQOL for these care partners.

An App-Based Just-in-Time Adaptive Self-management Intervention for Care Partners (CareQOL): Protocol for a Pilot Trial

BACKGROUND

Care partners (ie, informal family caregivers) of individuals with health problems face considerable physical and emotional stress, often with a substantial negative impact on the health-related quality of life (HRQOL) of both care partners and care recipients. Given that these individuals are often overwhelmed by their caregiving responsibilities, low-burden self-management interventions are needed to support care partners to ensure better patient outcomes.

OBJECTIVE

The primary objective of this study is to describe an intensive data collection protocol that involves the delivery of a personalized just-in-time adaptive intervention that incorporates passive mobile sensor data feedback (sleep and activity data from a Fitbit [Fitbit LLC]) and real time self-reporting of HRQOL via a study-specific app called CareQOL (University of Michigan) to provide personalized feedback via app alerts.

METHODS

Participants from 3 diverse care partner groups will be enrolled (care partners of persons with spinal cord injury, care partners of persons with Huntington disease, and care partners of persons with hematopoietic cell transplantation). Participants will be randomized to either a control group, where they will wear the Fitbit and provide daily reports of HRQOL over a 3-month (ie, 90 days) period (without personalized feedback), or the just-in-time adaptive intervention group, where they will wear the Fitbit, provide daily reports of HRQOL, and receive personalized push notifications for 3 months. At the end of the study, participants will complete a feasibility and acceptability questionnaire, and metrics regarding adherence and attrition will be calculated.

RESULTS

This trial opened for recruitment in November 2020. Data collection was completed in June 2021, and the primary results are expected to be published in 2022.

CONCLUSIONS

This trial will determine the feasibility and acceptability of an intensive app-based intervention in 3 distinct care partner groups: care partners for persons with a chronic condition that was caused by a traumatic event (ie, spinal cord injury); care partners for persons with a progressive, fatal neurodegenerative disease (ie, Huntington disease); and care partners for persons with episodic cancer conditions that require intense, prolonged inpatient and outpatient treatment (persons with hematopoietic cell transplantation).

The Experience of Caregivers Following a Moderate to Severe Traumatic Brain Injury Requiring ICU Admission

OBJECTIVES

Survivors of moderate and severe traumatic brain injury (TBI) require substantial care, much of which is ultimately provided by friends and family. We sought to describe the unmet needs of informal caregivers.

DESIGN

Qualitative, semistructured interviews with informal caregivers of moderate and severe TBI survivors were conducted 72 hours, 1 month, 3 months, and 6 months after injury.

SETTING

Intensive care unit of a level 1 trauma center.

PARTICIPANTS

Informal caregivers were friends or family who planned to provide care for the patient. Patients were 18 years or older with a moderate to severe TBI, and not expected to imminently die of their injuries.

MEASUREMENTS AND MAIN RESULTS

Eighteen patient-caregiver dyads were enrolled. Fifty-three interviews with caregivers were completed and analyzed over the course of 6 months. Three themes were identified in the qualitative analysis: caregiver burden, caregiver health-related quality of life, and caregiver needs for information and support.

CONCLUSIONS

This study provides new information about the experience of informal caregivers during the 6 months after their friend or family member survived a moderate to severe TBI. Interventions to promote caregiving may be a substantial opportunity to improve patient-centered outcomes following TBI.

Testing a Model of Resilience in Family Members of Relatives with Traumatic Brain Injury vs Spinal Cord Injury: Multigroup Analysis

OBJECTIVE

To test a model comprising explanatory (neurologic impairment, coping, personality) and mediating (resilience, self-efficacy, hope, social support) variables on psychological adjustment and burden among family caregivers of individuals with traumatic brain injury (TBI) vs spinal cord injury (SCI).

DESIGN

Structural equation modeling with multigroup analysis.

SETTING

Six rehabilitation centers across New South Wales and Queensland, Australia.

PARTICIPANTS

A total of 181 family members (N=181; 131 TBI, 50 SCI).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Connor-Davidson Resilience Scale, Eysenck Personality Questionnaire, Ways of Coping Questionnaire, General Self-Efficacy Scale, Herth Hope Scale, Medical Outcome Study Social Support Survey; and 4 measures of psychological adjustment including: Caregiver Burden Scale, Medical Outcomes Survey Short Form-36 (SF-36), General Health Questionnaire-28, and Positive and Negative Affect Scale.

RESULTS

The model for the aggregated sample demonstrated a very good model fit (χ²=47.42, df=39, ρ=0.167, normed fit index=.962, incremental fit index=.993, Tucker-Lewis index=.985, comparative fit index=.993, root-mean-squared error of approximation=.035). Multi-group analysis found significant commonalities in the pattern of relationships among variables across the 2 groups. In the only differences found, neuroticism was significantly more influential on burden in family members supporting individuals with TBI than family members of individuals with SCI. Furthermore, problem-focused coping was statistically more influential on positive affect in family members of individuals with TBI when compared with family members of individuals with SCI.

CONCLUSIONS

The study found significant similarities in the patterns of resilience and psychological adjustment among family caregivers of individuals with TBI and SCI.

Self-Care for Caregivers of Individuals Living With Multiple Sclerosis: Testing Mediation Models of Caregiver Stress, Health, and Self-Care

Individuals with Multiple Sclerosis (MS) often receive home health care, yet little research investigates the health of informal caregivers of individuals with MS. We tested a mediation model in which associations between caregiver stress and caregiver self-care were explained by each of four a priori caregiver health factors—caregiver negative affect, pain, tiredness, and functional limitations. Participants ( n = 60 informal caregivers) were recruited online or in-person from March—July 2018, and completed an online survey assessing demographics and their caregiving experience. After controlling for demographics, only caregiver tiredness mediated the association between caregiver stress and caregiver self-care. Therefore, caregiver tiredness may be an important construct for assessment, intervention, and future research, among caregivers of individuals with MS, and among anyone providing home health care. These findings have research, clinical, and policy implications.

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).

Measuring emotional suppression in caregivers of adults with traumatic brain injury

OBJECTIVE

Caregivers of individuals with traumatic brain injury (TBI) often feel pressure to maintain the appearance that they are emotionally well adjusted, despite feelings to the contrary. Because there are currently no measures examining this construct, this article focuses on the development of a new measure that is specific to caregivers of people with TBI.

DESIGN

A total of 533 caregivers of civilians with TBI (n = 218) or service members/veterans (SMVs) with TBI (n = 315) completed 43 emotional suppression items, as well as other patient-reported outcomes and an estimate of the functional ability of the person with TBI.

RESULTS

Exploratory and confirmatory factor analyses supported the retention of 25 items. Graded response model (GRM) analyses and differential item functioning (DIF) studies supported the retention of 21 items in the final measure. Expert review and GRM calibration data were used to develop a 6-item static short form (SF) and program a computer adaptive test (CAT). Internal consistency was excellent for both the CAT and SF (reliabilities ≥ 0.91); 3-week test-retest stability was good (all intraclass correlations ≥ 0.89). Convergent validity was supported by moderate associations between TBI-CareQOL Emotional Suppression and related measures (rs from 0.47 to 0.59); discriminant validity was supported by small correlations between Emotional Suppression and positive aspects of caregiving and physical health (rs from 0.14 to 0.28). Known-groups validity was also supported.

CONCLUSIONS

The new TBI-CareQOL Emotional Suppression CAT and 6-item short form is the first self-report measure of this construct in this population. Our findings suggest this new measure has strong psychometric properties. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Assessing vigilance in caregivers after traumatic brain injury: TBI-CareQOL Caregiver Vigilance

OBJECTIVE

Caregivers of individuals with traumatic brain injury (TBI) frequently experience anxiety related to the caregiver role. Often this is due to a caregiver's perceived need to avoid people and situations that might upset or "trigger" the care recipient. There are currently no self-report measures that capture these feelings; thus, this article describes the development and preliminary validation efforts for the TBI-Caregiver Quality of Life (CareQOL) Caregiver Vigilance item bank.

DESIGN

A sample of 532 caregivers of civilians (n = 218) or service members/veterans (SMVs; n = 314) with TBI completed 32 caregiver vigilance items, other measures of health-related quality of life (RAND-12, Patient-Reported Outcomes Measurement Information System [PROMIS] Depression, PROMIS Social Isolation, Caregiver Appraisal Scale), and the Mayo-Portland Adaptability Inventory-4.

RESULTS

The final item bank contains 18 items, as supported by exploratory and confirmatory factor analysis, item response theory graded response modeling (GRM), and differential item functioning investigations. Expert review and GRM calibration data informed the selection of a 6-item short form and programming of a computer adaptive test. Internal consistency reliability for the different administration formats were excellent (reliability coefficients ≥ .90). Three-week test-retest stability was supported (i.e., r ≥ .78). Correlations between vigilance and other self-report measures supported convergent and discriminant validity (0.01 ≤ r ≤ .69). Known-groups validity was also supported.

CONCLUSIONS

The new TBI-CareQOL Caregiver Vigilance computer adaptive test and corresponding 6-item short form were developed using established rigorous measurement development standards, providing the first self-report measure to evaluate caregiver vigilance. This development work indicates that this measure exhibits strong psychometric properties. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Reliability and validity data to support the clinical utility of the Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL)

OBJECTIVE

The Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) is a patient-reported outcome measurement system that is specific to caregivers of civilians and service members/veterans (SMVs) with traumatic brain injury (TBI). This measurement system includes 26 item banks that represent both generic (i.e., borrowed from existing measurement systems) and caregiver-specific components of health-related quality of life (HRQOL). This report provides reliability and validity data for measures within the TBI-CareQOL that have not previously been reported (i.e., 4 caregiver-specific and 7 generic measures of HRQOL).

DESIGN

Three hundred eighty-five caregivers of persons with TBI completed caregiver-specific computer adaptive tests (CATs) for Feelings of Loss-Self, Caregiver Strain, Caregiver-Specific Anxiety, and Feeling Trapped, as well as generic measures of HRQOL from complementary measurement systems (i.e., Neuro-QoL Positive Affect and Well-Being; PROMIS Sleep-Related Impairment; NIH Toolbox Perceived Stress, General Life Satisfaction, and Self Efficacy; TBI-QOL Resilience and Grief/Loss). Caregivers also completed several additional measures to establish convergent and discriminant validity, as well as the Mayo Portland Adaptability Index, 4th ed.

RESULTS

Findings support the internal consistency reliability (all alphas > .85) and test-retest stability (all alphas >.73) of the TBI-CareQOL measures. Convergent validity was supported by moderate to high correlations between the TBI-CareQOL measures and related measures, whereas discriminant validity was supported by low correlations between the TBI-CareQOL measures and unrelated constructs. Known-groups validity was also supported.

CONCLUSIONS

Findings support the reliability and validity of the item banks that comprise the TBI-CareQOL Measurement System. These measures should be considered for any standardized assessment of HRQOL in caregivers of civilians and SMVs with TBI. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Development of the life change adaptation scale for family caregivers of individuals with acquired brain injury

AIM

Life changes due to the sudden onset of acquired brain injury (ABI) are drastic personal and social changes that require adaptation and are also an important indicator of the quality of life of family caregivers. However, there are no instruments for evaluating life change adaptation among family caregivers of individuals with acquired brain injury. This study aimed to develop the Life Change Adaptation Scale (LCAS) for family caregivers of individuals with ABI and examine its reliability and validity.

METHODS

A cross-sectional study was conducted using a self-reported questionnaire. A total of 1622 family caregivers of individuals with ABI who belonged to 82 associations for families of individuals with ABI were selected as eligible participants. The construct validity was evaluated using a confirmatory factor analysis. Internal consistency was calculated using Cronbach's alpha. The K6 was also administered to assess the criterion-related validity of the LCAS.

RESULTS

In total, 339 valid responses were received. The confirmatory factor analysis identified eight items from two domains, "Changes in the appraisal of caregiving resources" and "Changes in the health belief as a caregiver" (goodness of fit index = 0.963, adjusted goodness of fit index = 0.926, comparative fit index = 0.986, root mean square error of approximation  = 0.043.) Cronbach's alpha was 0.84. The LCAS was negatively correlated with the K6 (r = -0.504; P<0.001).

CONCLUSIONS

The LCAS is a brief, easy-to-administer instrument that is reliable and valid for family caregivers of individuals with ABI. This study contributes to the assessment and identification by family caregivers of individuals with ABI who require aid in adapting to life changes. Further research should be undertaken to verify the predictive value in a longitudinal study and to attempt to apply the LCAS to assess a broader range of subjects in a wider range of settings.

Sleep impairment is related to health-related quality of life among caregivers of lower-functioning traumatic brain injury survivors

Objective: The purpose of this study was to examine perceived sleep-related impairment in caregivers of individuals with traumatic brain injury (TBI). Specifically, we examined the relationship between caregiver-perceived sleep-related impairment and different aspects of health-related quality of life (HRQOL) and explored whether these relationships were moderated by the perceived level of everyday function in the person with TBI. Method: Three hundred forty-one caregivers of individuals with TBI completed surveys to determine whether the association between sleep-related impairment and HRQOL was moderated by caregiver-perceived functional impairment of the person with injury. Participants completed measures from the Patient-Reported Outcomes Measurement Information System and the TBI-CareQOL. These measures were used to examine different aspects of HRQOL: caregiver-specific HRQOL, mental HRQOL, social HRQOL, and fatigue. The Mayo-Portland Adaptability Inventory-4 was used to measure caregiver perceptions of the level of everyday function in the person with injury. Results: Results indicated that caregiver-perceived sleep-related impairment was associated with each of the four HRQOL scores. This relationship was moderated by the caregiver-reported level of everyday function in the person with TBI for both caregiver-specific HRQOL and fatigue but not mental or social HRQOL. For caregiver-specific HRQOL and fatigue, caregiver-perceived sleep-related impairment was associated with worse HRQOL for those caring for individuals with lower perceived levels of everyday function, but not for those caring for individuals with higher levels of everyday function. Conclusions: Interventions to improve caregiver sleep and HRQOL should consider both psychosocial and environmental factors (i.e., factors related to the person with the TBI).

Is caregiver quality of life predicted by their perceived burden? A cross-sectional study of family caregivers of people with spinal cord injuries

STUDY DESIGN

Cross-sectional study.

OBJECTIVE

To identify predictors of quality of life (QoL) among family caregivers of people with spinal cord injuries (SCI), considering caregiver and care recipient characteristics, and to evaluate the predictive value of caregiver burden (CB) on the QoL of family caregivers.

SETTING

Multicenter study in four spinal units across Italy.

METHODS

Secondary analysis of the data obtained during the validation of the Italian version of the Caregiver Burden Inventory in Spinal Cord Injuries (CBI-SCI) questionnaire. In all, 176 family caregivers completed a socio-demographic questionnaire, the Short Form-36, the CBI-SCI, and the Modified Barthel Index. A first linear regression analysis was performed to identify independent predictors of each domain of caregiver QoL. A second linear regression analysis including CBI-SCI was then performed to evaluate the predictive value of CB on caregiver QoL.

RESULTS

Participants reported reduced physical and mental QoL. Significant predictors of lower scores in physical dimensions of QoL were older age and female gender. Contextual factors following SCI, such as economic difficulties and the presence of a formal caregiver, significantly predicted emotional QoL in family caregivers. Identified predictors explained 13-32% of variance. CB was a significant predictor (p < 0.001) when added to all proposed models, increasing the explained variance from 7 to 26%.

CONCLUSION

Neither the clinical characteristics of, nor the relationship with care recipients predicted a worse caregiver QoL, whereas the CB did. The CB was a strong predictor of QoL among family caregivers and should be kept to a minimum to promote caregiver well-being.

A tool for measuring burden in activities and participation of clients with acquired brain injury: the FINAH-instrument

PRIMARY OBJECTIVE

The objective of this study was to design an instrument to screen for burden in the daily life of both the client with acquired brain injury (ABI) and their nonprofessional caregiver.

RESEARCH DESIGN

Exploratory research Methods and Procedures: Based on a survey amongst stakeholder organizations, the FINAH-instrument is designed as a digital self-assessment questionnaire, based on ICF-framework. A test survey of the FINAH instrument is conducted on both clients, nonprofessional caregivers and healthcare professionals.

MAIN OUTCOMES AND RESULTS

The relative burden per item for clients and nonprofessional caregivers is most prominent in the domains of fatigue, cognitive and emotional consequences, self-care and mobility. The estimation of burden for clients and nonprofessional caregiver by healthcare professionals showed an overall 65% correct estimation by the healthcare professional. 19% of the items showed underestimation of burden, while 16% showed overestimation.

CONCLUSIONS

These results show that FINAH can ameliorate the estimation of the health care professional on the self-assessed burden of clients and nonprofessional caregivers, thus substantiating a more client-centred approach.

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.

Health literacy, health outcomes, and the caregiver role in traumatic brain injury

Purpose/Objective: The purpose of this study is to estimate the occurrence of low health literacy among caregivers of people with traumatic brain injury (TBI), and to evaluate associations of health literacy with caregiver health-related quality of life (HRQOL) and perceptions of the caregiving role. Research Method/Design: The TBI-CareQOL measurement system assesses important self-reported outcomes for caregivers of civilians or service members/veterans (SMVs) with TBI. The validation phase included the Health Literacy Assessment Using Talking Touchscreen Technology (Health LiTT) measure. Multivariable regression evaluated the impact of low health literacy on generic and TBI-specific HRQOL and appraisals of the caregiving role, adjusted for caregiver gender, race/ethnicity and education, and the functional status of the TBI care recipient. Results: Among 131 caregivers, 28 (21%) had low health literacy. Compared with the high health literacy group, the group with low health literacy had fewer women, more racial/ethnic minorities, and lower education (all p < .05). The low health literacy group reported more subjective caregiving burden, less satisfaction with their relationship with the TBI recipient, less caregiving mastery, and poorer physical health (all p < .05). There were no differences between health literacy groups in caregiving ideology, caregiver-specific HRQOL or general mental health. Conclusions/Implications: A better understanding of the links between health literacy and caregiver HRQOL and the caregiving role can help identify strategies to meet the needs of this underserved population. Tailored interventions for caregivers with low health literacy could improve outcomes for both the caregiver and the care recipient. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Do emotional distress and functional problems in persons with traumatic brain injury contribute to perceived sleep-related impairment in caregivers?

OBJECTIVE

The goal of this study was to examine the association between characteristics of persons with traumatic brain injury (PwTBI) and perceived sleep-related impairment of the caregivers.

METHOD

Fifty-two dyads (n = 23 civilians, n = 29 service members/veterans [SMVs]) were enrolled. Caregivers completed the Patient-Reported Outcomes Measurement Information System Sleep-Related Impairment computer adaptive test, and PwTBI completed Quality of Life in Neurological Disorders measures of depression, anxiety, anger, cognitive functioning, and upper and lower extremity functioning. Hierarchical linear regression models, stratified by civilian/SMV group, were employed to assess prediction of caregiver-perceived sleep-related impairment from emotional distress of the PwTBI (anxiety, depressed mood, and anger) and perceived functional status of the PwTBI (cognitive, upper extremity, lower extremity functioning).

RESULTS

Compared with caregivers of civilians, caregivers of SMVs reported higher perceived sleep-related impairment. Regression results showed that characteristics of the PwTBI accounted for moderate amounts of variance in the sleep-related impairment of caregivers of both civilians and SMVs. Within-group analyses showed that the strongest predictor of sleep-related impairment of caregivers of civilians was self-reported cognitive function of the PwTBI (β = -0.82, p = .08); the strongest predictor of sleep-related impairment of caregivers of SMVs was self-reported anger of the PwTBI (β = 0.54, p = .07).

CONCLUSIONS

In both caregivers of civilians and SMVs with TBI, characteristics of the PwTBI were related to perceived caregiver sleep-related impairment. These preliminary data can inform future research with larger samples that examine the impact of multiple characteristics of the caregiver and care recipient on caregiver sleep. Findings highlight the potential importance of considering the dynamics of the dyad in rehabilitation programming not only for the PwTBI but for caregivers as well.

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.

TBI-CareQOL family disruption: Family disruption in caregivers of persons with TBI

PURPOSE

Family disruption is often an indirect consequence of providing care for a person with traumatic brain injury (TBI). This article describes the development and preliminary validation of a Family Disruption scale designed for inclusion within the TBI-CareQOL measurement system.

METHOD/DESIGN

Five hundred thirty-four caregivers of persons with TBI (service member/veteran n = 316; civilian n = 218) completed the Family Disruption scale, alongside several other measures of caregiver strain and health-related quality of life. Classical test theory and item response theory (IRT)-based analyses were conducted to develop, and establish reliability and validity of, this scale.

RESULTS

Exploratory and confirmatory factor analysis, as well as Samejima's graded response model-related IRT fit analyses, supported the development of a 3-item scale. This final scale is scored on a T score metric (M = 50; SD = 10); higher scores are indicative of more family disruption. Reliability (internal consistency; test-retest stability) was supported for both caregiver groups, and average administration times were under 10 s. Convergent and discriminant validity were supported by strong correlations between Family Disruption and measures of caregiver burden, and smaller correlations with positive aspects of caregiving. As evidence of known-groups validity, caregivers of lower-functioning persons with TBI experienced more family disruption than caregivers of higher functioning individuals.

CONCLUSIONS

The TBI-CareQOL Family Disruption scale is a brief, reliable, and valid assessment of caregiver perceptions of how caring for an individual with a TBI interferes with family life. This measure is well-suited for inclusion in studies seeking to support family functioning in persons with TBI. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Measuring Self-Reported Physical Function in Individuals With TBI: Development of the TBI-QOL Mobility and Upper Extremity Item Banks and Short Forms

OBJECTIVES

To describe the development and field testing of the patient-reported outcome measures of Mobility and Upper Extremity function from the Traumatic Brain Injury Quality of Life (TBI-QOL) measurement system, and to evaluate the use of computer adaptive testing.

SETTING

Five rehabilitation facilities funded as part of the TBI Model Systems network.

PARTICIPANTS

Individuals with complicated mild, moderate, or severe traumatic brain injury (n = 590).

INTERVENTIONS

Not available.

OUTCOME MEASURES

TBI-QOL Mobility and Upper Extremity item banks.

RESULTS

Item response theory and factor analyses supported the unidimensionality of the Mobility and Upper Extremity banks. Descriptive statistics showed a ceiling effect for both measures. Simulated computer adaptive tests (CATs) showed that measurement precision was maintained across administration formats for both measures. The Upper Extremity CAT showed a loss of precision for individuals without impairment and that a higher number of items were required to achieve sufficiently precise measurement, compared to the Mobility CAT.

CONCLUSIONS

The TBI-QOL Upper Extremity and Mobility item banks achieved good breadth of coverage, particularly among those individuals who have experienced some degree of functional limitation. The use of CAT administration minimizes respondent burden, while allowing for the comprehensive assessment of adults with TBI. The combined use of the TBI-QOL with performance-based measures could guide the development of targeted rehabilitation treatments.

Experiences and Perceptions of Hospitalization and Recovery of Older Adults and Their Caregivers Following Traumatic Brain Injury: "Not Knowing"

The purpose of the current study is to describe the experience and perceptions of older adults and their caregivers following hospitalization for mild or moderate traumatic brain injury (TBI). Qualitative analysis of data obtained in individual semi-structured interviews with older adults and their caregivers (N = 11, five dyads and one individual) was performed to capture the perceptions and experiences of the survivor and their caregivers about the acute injury, hospitalization, and recovery. Data were collected over a 2-month period following discharge from the hospital. Open coding and constant comparative analysis generated codes that were revised throughout the analysis and reformulated into thematic descriptions. As a result, seven interrelated themes were identified. These findings can be used to implement interventions focused on recovery, communication, teaching, patient outcomes, and satisfaction.

Group Differences Among Caregivers of Civilians and Service Members or Veterans With Traumatic Brain Injury

OBJECTIVE

To examine group differences among caregivers of service members or veterans (SMVs) and civilians with traumatic brain injury (TBI).

DESIGN

An observational research study examining the group differences between caregivers of SMVs and civilians with TBI. The data presented was collected as part of a larger study that calibrated and validated the Traumatic Brain Injury-Care Quality of Life (TBI-CareQOL) item banks.

SETTING

Participants in this multicenter study completed an online survey via a study-specific website. Surveys were completed at the study site, at home, or via phone interview. Civilian caregivers were recruited from 4 rehabilitation hospitals and caregivers of SMVs were recruited through community outreach and collaboration with the Hearts of Valor.

PARTICIPANTS

Participants (N=473) consisted of 344 caregivers of civilians with TBI and 129 caregivers of SMVs with TBI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Zarit Burden Interview Scale, TBI-CareQOL, and Mayo Portland Adaptability Inventory, 4th revision (MPAI-4).

RESULTS

Of the independent variables included in the logistic regression model that classified military-affiliated vs civilian caregivers, 5 were statistically significant: age, spousal status, time since injury, MPAI-4 Adjustment, and TBI-CareQOL Feeling Trapped.

CONCLUSIONS

The results indicate that caregivers of SMVs were more likely to report worse emotional and social adjustment among the individuals with TBI and caregivers of SMVs were more likely to report greater levels of feeling trapped by their caregiving duties.

Understanding Health-Related Quality of Life in Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury: Reliability and Validity Data for the TBI-CareQOL Measurement System

OBJECTIVES

To establish the reliability and validity of the newly developed TBI-CareQOL patient-reported outcome (PRO) measures in caregivers of civilians and service members/veterans (SMVs) with traumatic brain injury (TBI) so that they can be used with confidence in clinical research and practice.

DESIGN

Computer-based surveys delivered through an on-line data capture platform.

SETTING

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

PARTICIPANTS

Caregivers (N=560) of individuals with TBI; this included 2 different study samples: 344 caregivers of civilians with TBI and 216 caregivers of SMVs with TBI.

INTERVENTION

Not Applicable.

MAIN OUTCOME MEASURES

Five Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) item banks.

RESULTS

Reliabilities for the TBI-CareQOL measures were excellent (all Cronbach's α >.88); 3-week test-retest reliability ranged from .75 to .90 across the 2 samples. Convergent validity was supported by moderate to high associations among the TBI-CareQOL measures and moderate correlations between the TBI-CareQOL measures and other measures of health-related quality of life (HRQOL) and caregiver burden. Discriminant validity was supported by low correlations between the TBI-CareQOL measures and less-related constructs (eg, caregiver satisfaction). Known-groups validity was supported: caregivers of individuals that were low functioning had worse HRQOL than caregivers of high-functioning individuals.

CONCLUSIONS

Results provide psychometric support for the new TBI-CareQOL item banks. As such, these measures fill a significant gap in the caregiver literature where sensitive PRO measures that capture changes in HRQOL are needed to detect improvements for interventions designed to assist family caregivers.

The TBI-CareQOL Measurement System: Development and Preliminary Validation of Health-Related Quality of Life Measures for Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury

OBJECTIVE

To develop a new measurement system, the Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL), that can evaluate both general and caregiving-specific aspects of health-related quality of life (HRQOL) in caregivers of persons with traumatic brain injury (TBI).

DESIGN

New item pools were developed and refined using literature reviews, qualitative data from focus groups, and cognitive debriefing with caregivers of civilians and service members/veterans with TBI, as well as expert review, reading level assessment, and translatability review; existing item banks and new item pools were assessed using an online data capture system. Exploratory and confirmatory factor analysis, item response theory, and differential item functioning analyses were utilized to develop new caregiver-specific item banks. Known-groups validity was examined using a series of independent samples t tests comparing caregivers of low-functioning vs high-functioning persons with TBI for each of the new measures, as well as for 10 existing Patient-Reported Outcomes Measurement Information System (PROMIS) measures.

SETTING

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

PARTICIPANTS

Caregivers (N=560) of civilians (n=344) or service members/veterans with TBI (n=216).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The TBI-CareQOL measurement system (including 5 new measures and 10 existing PROMIS measures).

RESULTS

Exploratory and confirmatory factor analysis, item response theory, and differential item functioning analyses supported the development of 5 new item banks for Feelings of Loss-Self, Feelings of Loss-Person with TBI, Caregiver-Specific Anxiety, Feeling Trapped, and Caregiver Strain. In support of validity, individuals who were caring for low-functioning persons with TBI had significantly worse HRQOL than caregivers that were caring for high-functioning persons with TBI for both the new caregiver-specific HRQOL measures, and for the 10 existing PROMIS measures.

CONCLUSIONS

The TBI-CareQOL includes both validated PROMIS measures and newly developed caregiver-specific measures. Together, these generic and specific measures provide a comprehensive assessment of HRQOL for caregivers of civilians and service members/veterans with TBI.

The Development of a New Computer Adaptive Test to Evaluate Feelings of Being Trapped in Caregivers of Individuals With Traumatic Brain Injury: TBI-CareQOL Feeling Trapped Item Bank

OBJECTIVE

To develop a new patient-reported outcome measure that captures feelings of being trapped that are commonly experienced by caregivers of individuals with traumatic brain injury (TBI).

DESIGN

Cross-sectional.

SETTING

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

PARTICIPANTS

Caregivers (N=560) of civilians with TBI (n=344) and caregivers of service members/veterans with TBI (n=216).

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Feeling Trapped item bank.

RESULTS

From an initial item pool of 28 items, exploratory and confirmatory factor analyses supported the retention of 16 items. After graded response model (GRM) and differential item functioning analyses were conducted, 15 items were retained in the final measure. GRM calibration data, along with clinical expert input, were used to choose a 6-item, static short form (SF), and the calibration data were used for programming of the TBI-CareQOL Feeling Trapped computer adaptive test (CAT). CAT simulation analyses produced an r=0.99 correlation between CAT scores and the full item bank. Three-week short-form test-retest reliability was very good (r=0.84).

CONCLUSIONS

The new TBI-CareQOL Feeling Trapped item bank was developed to provide a sensitive and efficient examination of the effect that feelings of being trapped, due to the caregiver role, have on health-related quality of life for caregivers of individuals with TBI. Both the CAT and corresponding 6-item SF demonstrate excellent psychometric properties. Future work is needed to establish the responsiveness of this measure to clinical interventions for these caregivers.

The Development of a New Computer-Adaptive Test to Evaluate Strain in Caregivers of Individuals With TBI: TBI-CareQOL Caregiver Strain

OBJECTIVE

To develop a new measure of caregiver strain for use in caregivers of individuals with traumatic brain injury (TBI), Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Caregiver Strain.

DESIGN

Qualitative data, literature reviews, and cross-sectional survey study.

SETTING

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

PARTICIPANTS

Caregivers (N=560) of civilians (n=344) or service members/veterans (SMVs) with TBI (n=216).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

TBI-CareQOL Caregiver Strain Item Bank.

RESULTS

Exploratory and confirmatory factor analyses, a graded response model (GRM) and differential item functioning supported the retention of 33 items in the final measure. GRM calibration data was used to inform the selection of a 6-item static short form, and to program the TBI-CareQOL Caregiver Strain computer-adaptive test (CAT). CAT simulation analyses indicated a 0.97 correlation between the CAT scores and the full item-bank. Three-week test-retest reliability was strong (r=0.83).

CONCLUSIONS

The new TBI-CareQOL Caregiver Strain CAT and corresponding 6-item short form were developed using established rigorous measurement development standards; this is the first self-reported measure developed to evaluate caregiver strain in caregivers of individuals with TBI.

Understanding Health-related Quality of Life in Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury: Establishing the Reliability and Validity of PROMIS Mental Health Measures

OBJECTIVE

To provide important reliability and validity data to support the use of the Patient-Reported Outcomes Measurement Information System (PROMIS) mental health measures in caregivers of civilians or service members/veterans (SMVs) with traumatic brain injury (TBI).

DESIGN

Patient-reported outcome surveys administered through an electronic data collection platform.

SETTING

Three TBI model systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility.

PARTICIPANTS

Caregivers (N=560) of individuals with a documented TBI (344 civilians and 216 military).

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

PROMIS anxiety, depression, and anger item banks.

RESULTS

Internal consistency for all the PROMIS Mental Health item banks was very good (all α>.86) and 3-week test-retest reliability was good to adequate (ranged from .65 to .85). Convergent validity and discriminant validity of the PROMIS measures were also supported. Caregivers of individuals who were low functioning had worse emotional health-related quality of life (HRQOL) (as measured by the 3 PROMIS measures) than caregivers of high-functioning individuals, supporting known groups validity. Finally, levels of distress, as measured by the PROMIS measures, were elevated for those caring for low-functioning individuals in both samples (rates ranged from 26.2% to 43.6% for caregivers of low-functioning individuals).

CONCLUSIONS

Results support the reliability and validity of the PROMIS anxiety, depression, and anger item banks in caregivers of civilians and SMVs with TBI. Ultimately, these measures can be used to provide a standardized assessment of HRQOL because it relates to mental health in these caregivers.

Survey response burden in caregivers of civilians and service members/veterans with traumatic brain injury

PURPOSE

Caregivers have expressed interest in survey research, yet there is limited information available about survey response burden, ie, the time, effort, and other demands needed to complete the survey. This may be particularly important for caregivers due to excessive time demands and/or stress associated with caregiving.

METHOD

Survey response burden indicators were collected as part of a study to develop and validate a patient-reported outcome (PRO) measurement system for caregivers of civilians or service members/veterans (SMVs) with traumatic brain injury (TBI).

RESULTS

Compared to the group caring for civilians (n=335), the group caring for SMVs (n=123) was comprised of all women, was younger, had fewer racial/ethnic minorities, had more education, and nearly all were the spouse of a person with TBI. All PRO outcomes were poorer for the group caring for SMVs. Although the caregivers of SMVs had poorer PRO outcomes compared to caregivers of civilians, they were more likely to report that they would recommend the study to others. Caregivers with less education and those from racial/ethnic minority groups had more favorable ratings of their study participation experience, even though they needed more help using the computer or answering the questions.

CONCLUSION

The results of this study provide useful information about the acceptability of computer-based survey administration for caregiver PROs. PROs are widely gathered in clinical and health services research and could be particularly useful in TBI care programs. More data are needed to determine the best assessment strategies for individuals with lower education who are likely to require some assistance completing PRO surveys. Studies evaluating PROs administered by multimedia platforms could help researchers and clinicians plan the best strategies for assessing health-related quality of life in TBI caregivers.

Burden and Psychological Distress of Intensive Care Unit Caregivers of Traumatic Brain Injury Patients

Aim

Admission to Intensive Care Unit (ICU) is a stressful event and unforeseen crisis for the caregivers. Burden and psychosocial distress among caregivers in the ICU were unexplored. Therefore, the current study was aimed to assess the caregivers’ burden and psychological distress among caregivers of traumatic brain injury (TBI) patients at emergency ICU during hospitalization.

Materials and Methods

A total of 60 caregivers recruited by using purposive sampling method with descriptive research design. Consent was obtained. Interview schedule of family for depression, anxiety, stress scale (DAS-21) were administered. The data were analyzed by using SPSS. Descriptive statistics and independent burden t-test were used.

Results

Results revealed that male caregivers (75%) and female caregivers (25%) took part in the study. Caregivers' mean age was found to be 35.22±11.29 years. Most of the TBI survivors admitted in ICU had severe injury (8.30±3.63). Mean scores showed that caregivers had experienced financial burden (6.28±2.36), severe depression (12.15±4.84), and a moderate level of anxiety (12.85±5.20). Independent t-test showed significant difference in caregiving burden between male and female caregivers at ICU (Male = 18.43±4.83; Female = 14.29±4.83; t = 2.16; p <0.035). Overall, caregivers experienced higher family burden and severe psychological distress at ICU.

Conclusion

There is an immediate need to assess psychological distress and family burden of caregivers at ICU and provide timely psychosocial intervention.

Caring for an individual with mild cognitive impairment: a qualitative perspective of health-related quality of life from caregivers

OBJECTIVES

Little is known regarding the effect that caring for an individual with Mild Cognitive Impairment (MCI) has on health-related quality of life (HRQOL). We sought to identify the most important aspects of HRQOL related to caring for an individual with MCI.

METHODS

Six focus groups were conducted with caregivers of individuals with MCI (n = 32). Qualitative frequency analysis was used to analyze the data.

RESULTS

Findings indicated that caregivers most frequently discussed social health, including changes in social roles and an increased need for social support (51.2% of the total discussion). This was followed by mental health concerns (37.9%) centering on anger/frustration, and a need for patience in the caregiving role, as well as caregiver-specific anxiety. Other topics included physical health (10.0%; including the impact that stress and burden have on medical heath), and caregivers' cognitive health (0.9%; including memory problems in relation to caregiver strain, sleep disruption, and cognitive fatigue).

CONCLUSIONS

Findings illustrate the multiple domains of HRQOL that are affected in individuals providing care for someone with MCI. Moreover, the findings highlight the need for extending support services to MCI caregivers, a group that is typically not offered support services due to the 'less severe' nature of an MCI diagnosis.

Understanding Health-Related Quality of Life of Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury: Establishing the Reliability and Validity of PROMIS Social Health Measures

OBJECTIVE

To examine the reliability and validity of the short form (SF) and computer adaptive test (CAT) versions of the Patient-Reported Outcomes Measurement Information System (PROMIS) measures of social health of caregivers of civilians and service members/veterans (SMVs) with traumatic brain injury (TBI).

DESIGN

Self-report questionnaires administered through an online data collection platform.

SETTING

Hospital and community-based outreach at 3 TBI Model Systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility.

PARTICIPANTS

Caregivers (N=560) (344 civilians and 216 military) of individuals with a documented TBI.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

A total of 5 PROMIS social health measures.

RESULTS

All 5 PROMIS social health measures exceeded the a priori criterion for internal consistency reliability (≥0.70); most PROMIS measures met the criterion for test-retest reliability (≥0.70) in the civilian sample; in the SMV sample, test-retest reliability was generally below this criterion, except for social isolation. For both samples, convergent validity was supported by moderate correlations between the 5 PROMIS social health measures and related measures, and discriminant validity was supported by low correlations between PROMIS social health measures and measures of dissimilar constructs. Most PROMIS scores indicated significantly worse social health in both samples of those caring for individuals who were low functioning. Finally, impairment rates in social health were elevated for those caring for low-functioning individuals, especially in the SMV sample.

CONCLUSIONS

The PROMIS CAT and SF social health measures have potential clinical utility for use in caregivers of civilians and SMVs with TBI.

The Development of Two New Computer Adaptive Tests To Evaluate Feelings of Loss in Caregivers of Individuals With Traumatic Brain Injury: TBI-CareQOL Feelings of Loss-Self and Feelings of Loss-Person With Traumatic Brain Injury

OBJECTIVE

To develop new patient-reported outcome (PRO) measures to better understand feelings of loss in caregivers of individuals with traumatic brain injury (TBI).

DESIGN

Cross-sectional survey study.

SETTING

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

PARTICIPANTS

Caregivers (N=560) of civilians with TBI (n=344) or service members/veterans (SMVs) with TBI (n=216).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Feelings of Loss-Self and TBI-CareQOL Feelings of Loss-Person with Traumatic Brain Injury item banks.

RESULTS

While the initial exploratory and confirmatory factor analyses of the feelings of loss item pool (98 items) potentially supported a unidimensional set of items, further analysis indicated 2 different factors: Feelings of Loss-Self (43 items) and Feelings of Loss-Person with TBI (20 items). For Feelings of Loss-Self, an additional 13 items were deleted due to item-response theory-based item misfit; the remaining 30 items had good overall model fit (comparative fit index [CFI]=0.96, Tucker-Lewis index [TLI]=.96, root mean squared error of approximation [RMSEA]=.10). For Feelings of Loss-Other, 1 additional item was deleted due to an associated high correlated error modification index value; the final 19 items evidenced good overall model fit (CFI=0.97, TLI=.97, RMSEA=.095). The final item banks were developed to be administered as either a Computer Adaptive Test (CAT) or a short-form (SF). Clinical experts approved the content of the 6-item SFs of the 2 measures (3-week test-retest was r=.87 for Feelings of Loss-Self and r=.85 for Feelings of Loss-Person with TBI).

CONCLUSIONS

The findings from this study resulted in the development of 2 new PROs to assess feelings of loss in caregivers of individuals with TBI; TBI-CareQOL Feelings of Loss-Self and TBI-CareQOL Feelings of Loss-Person with TBI. Good psychometric properties were established and an SF was developed for ease of use in clinical situations. Additional research is needed to determine concurrent and predictive validity of these measures in the psychological treatment of those caring for persons with TBI.

DESIGN

Cross-sectional survey study.

SETTING

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

PARTICIPANTS

Three hundred forty-four caregivers of civilians with TBI and 216 caregivers of service members/veterans with TBI (N=560).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

TBI-CareQOL Caregiver-Specific Anxiety item bank.

RESULTS

The retention of 40 Caregiver-Specific Anxiety items was supported by exploratory and confirmatory factor analyses. Graded response model (GRM) and differential item functioning analyses supported the retention of 33 items in the final measure. Expert review and GRM calibration data was used to select a 6-item static short form, and GRM calibration data was used to program the TBI-CareQOL Caregiver-Specific Anxiety computer adaptive test (CAT).

CONCLUSIONS

Established, rigorous measurement development standards were used to develop the new TBI-CareQOL Caregiver-Specific Anxiety CAT and corresponding 6-item short form. This measure is the first patient-reported outcome measure designed to assess caregiver-specific anxiety in caregivers of individuals with TBI. The measure exhibits strong psychometric properties.

Understanding Health-Related Quality of Life in Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury: Establishing the Reliability and Validity of PROMIS Fatigue and Sleep Disturbance Item Banks

OBJECTIVE

To examine the reliability and validity of Patient-Reported Outcomes Measurement Information System (PROMIS) measures of sleep disturbance and fatigue in traumatic brain injury (TBI) caregivers and to determine the severity of fatigue and sleep disturbance in these caregivers.

DESIGN

Cross-sectional survey data collected through an online data capture platform.

SETTING

A total of 4 rehabilitation hospitals and Walter Reed National Military Medical Center.

PARTICIPANTS

Caregivers (N=560) of civilians (n=344) and service member/veterans (SMVs) (n=216) with TBI.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

PROMIS sleep and fatigue measures administered as both computerized adaptive tests (CATs) and 4-item short forms (SFs).

RESULTS

For both samples, floor and ceiling effects for the PROMIS measures were low (<11%), internal consistency was very good (all α≥0.80), and test-retest reliability was acceptable (all r≥0.70 except for the fatigue CAT in the SMV sample r=0.63). Convergent validity was supported by moderate correlations between the PROMIS and related measures. Discriminant validity was supported by low correlations between PROMIS measures and measures of dissimilar constructs. PROMIS scores indicated significantly worse sleep and fatigue for those caring for someone with high levels versus low levels of impairment.

CONCLUSIONS

Findings support the reliability and validity of the PROMIS CAT and SF measures of sleep disturbance and fatigue in caregivers of civilians and SMVs with TBI.

Characteristics and Concerns of Caregivers of Adults With Traumatic Brain Injury

OBJECTIVE

To describe the characteristics of caregivers of adults with traumatic brain injury (TBI) and their concerns in the first months after community discharge of the TBI survivor.

DESIGN

Secondary analysis of data collected during a parallel-group randomized controlled trial.

SETTING

Community.

PARTICIPANTS

A total of 153 consecutively enrolled caregivers of adults with moderate to severe TBI discharged to the community following acute and/or rehabilitation care at a Level I trauma center with 71 caregivers in the treatment group identifying concerns as part of the intervention procedures.

MAIN MEASURES

Caregiver demographics, caregiver-survivor relationship characteristics, caregiver activity changes, and concerns targeted by caregivers for education and problem-solving via biweekly phone calls.

RESULTS

Thirty-nine percent of caregivers were spouses and 35% parents. Sixty-five percent lived in the same house as the survivor preinjury with 86% in touch daily to several times per week. Concerns targeted by more than one-third of caregivers related to managing their emotional adjustment, strategies for getting things done, managing survivor emotions and behaviors, and engaging in healthful habits.

CONCLUSIONS

Caregivers of TBI survivors targeted personal concerns relating to their own emotional adjustment and participation as well as concerns relating to symptoms and recovery of the TBI survivor to address through education and problem-solving.

Outcome Measures for Persons With Moderate to Severe Traumatic Brain Injury: Recommendations From the American Physical Therapy Association Academy of Neurologic Physical Therapy TBI EDGE Task Force

BACKGROUND AND PURPOSE

The use of standardized outcome measures (OMs) is essential in assessing the effectiveness of physical therapy (PT) interventions. The purposes of this article are (1) to describe the process used by the TBI EDGE task force to assess the psychometrics and clinical utility of OMs used with individuals with moderate to severe traumatic brain injury (TBI); (2) to describe the consensus recommendations for OM use in clinical practice, research, and professional (entry-level) PT education; and (3) to make recommendations for future work.

METHODS

An 8-member task force used a modified Delphi process to develop recommendations on the selection of OMs for individuals with TBI. A 4-point rating scale was used to make recommendations based on practice setting and level of ambulation. Recommendations for appropriateness for research use and inclusion in entry-level education were also provided.

RESULTS

The TBI EDGE task force reviewed 88 OMs across the International Classification of Functioning, Disability, and Health (ICF) domains: 15 measured body functions/structure only, 21 measured activity only, 23 measured participation only, and 29 OMs covered more than 1 ICF domain.

DISCUSSION AND CONCLUSIONS

Recommendations made by the TBI EDGE task force provide clinicians, researchers, and educators with guidance for the selection of OMs. The use of these recommendations may facilitate identification of appropriate OMs in the population with moderate to severe TBI. TBI EDGE task force recommendations can be used by clinicians, researchers, and educators when selecting OMs for their respective needs. Future efforts to update the recommendations are warranted in order to ensure that recommendations remain current and applicable.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, http://links.lww.com/JNPT/A140).

Experiences of patients with traumatic brain injury and their carers during transition from in-patient rehabilitation to the community: a qualitative study

PURPOSE

To explore the experiences of individuals who have had a severe traumatic brain injury (TBI) and their carers in the first month post-discharge from in-patient rehabilitation into living in the community.

METHOD

Using a qualitative approach underpinned by critical realism, we explored the narratives of 10 patients and nine carers using semi-structured interviews approximately one month post-discharge. Thematic analysis was carried out independently by two researchers.

RESULTS

Firstly, perceptions of support were mixed but many patients and carers felt unsupported in the inpatient phase, during transitions between units and when preparing for discharge. Secondly, they struggled to accept a new reality of changed abilities, loss of roles and loss of autonomy. Thirdly, early experiences post-discharge exacerbated fears for the future.

CONCLUSIONS

Most patients and carers struggled to identify a cohesive plan that supported their transition to living in the community. Access to services required much persistence on the part of carers and tended to be short-term, and therefore did not meet their long-term needs. We propose the need for a case manager to be involved at an early stage of their rehabilitation and act as a key point for information and access to on-going rehabilitation and other support services. Implications for Rehabilitation Traumatic Brain Injury (TBI) is a major cause of long-term disability. It can affect all areas of daily life and significantly reduce quality of life for both patient and carer. Professionals appear to underestimate the change in abilities and impact on daily life once patients return home. Community services maintain a short-term focus, whereas patients and carers want to look further ahead - this dissonance adds to anxiety. The study's findings on service fragmentation indicate an urgent need for better integration within health services and across health, social care and voluntary sectors. A link person/case manager who oversees the patient journey from admission onwards would help improve integrated care and ensure the patient, and carer, are at the center of service provision.

Caring for our wounded warriors: A qualitative examination of health-related quality of life in caregivers of individuals with military-related traumatic brain injury

The purpose of this study was to develop a conceptual framework that captures aspects of health-related quality of life (HRQOL) for caregivers of individuals with military-related traumatic brain injury (TBI). We analyzed qualitative data from nine focus groups composed of caregivers of wounded warriors with a medically documented TBI. Focus group participants were recruited through hospital-based and/or community outreach efforts at the Walter Reed National Military Medical Center, the University of Michigan, and Hearts of Valor support groups (Tennessee and Washington). Participants were the caregivers (n = 45) of wounded warriors who had sustained a mild, moderate, severe, or penetrating TBI. Qualitative frequency analysis indicated that caregivers most frequently discussed social health (44% of comments), followed by emotional (40%) and physical health (12%). Areas of discussion that were specific to this population included anger regarding barriers to health services (for caregivers and servicemembers), emotional suppression (putting on a brave face for others even when things are not going well), and hypervigilance (controlling one's behavior/environment to prevent upsetting the servicemember). Caring for wounded warriors with TBI is a complex experience that positively and negatively affects HRQOL. While some aspects of HRQOL can be evaluated with existing measures, evaluation tools for other important components do not exist. The development of military-specific measures would help facilitate better care for these individuals.

Traumatic brain injury caregivers: A qualitative analysis of spouse and parent perspectives on quality of life

The objective of this qualitative study was to examine how family caregivers of individuals with traumatic brain injury (TBI) describe their quality of life in the context of their caregiving role. Fifty-two caregivers of adults with moderate or severe TBI (n = 31 parents, n = 21 partners/spouses; 77% female; mean age = 57.96 years, range = 34-78 years) were recruited from three data collection sites to participate in focus groups. Thematic content analysis was used to identify two main meta-themes: Caregiver Role Demands and Changes in Person with TBI. Prominent sub-themes indicated that caregivers are (1) overburdened with responsibilities, (2) lack personal time and time for self-care, (3) feel that their life is interrupted or lost, (4) grieve the loss of the person with TBI, and (5) endorse anger, guilt, anxiety, and sadness. Caregivers identified a number of service needs. A number of sub-themes were perceived differently by partner versus parent caregivers. The day-to-day responsibilities of being a caregiver as well as the changes in the person with the TBI present a variety of challenges and sources of distress for caregivers. Although services that address instrumental as well as emotional needs of caregivers may benefit caregivers in general, the service needs of parent and partner caregivers may differ.

Toward an evidence-based patient-provider communication in rehabilitation: linking communication elements to better rehabilitation outcomes

Background:

There is a growing interest in linking aspects of patient-provider communication to rehabilitation outcomes. However, the field lacks a conceptual understanding on: (a) ‘how’ rehabilitation outcomes can be improved by communication; and (b) through ‘which’ elements in particular. This article elaborates on the conceptual developments toward informing further practice and research.

Methods:

Existing models of communication in healthcare were adapted to rehabilitation, and its outcomes through a comprehensive literature review.

Results:

After depicting mediating mechanisms and variables (e.g. therapeutic engagement, adjustment toward disability), this article presents the ‘4 Rehab Communication Elements’ deemed likely to underpin rehabilitation outcomes. The four elements are: (a) knowing the person and building a supportive relationship; (b) effective information exchange and education; (c) shared goal-setting and action planning; and (d) fostering a more positive, yet realistic, cognitive and self-reframing.

Discussion:

This article describes an unprecedented, outcomes-oriented approach toward the design of rehabilitation communication, which has resulted in the development of a new intervention model: the ‘4 Rehab Communication Elements’. Further trials are needed to evaluate the impact of this whole intervention model on rehabilitation outcomes.
