Family caregiving of persons following neurotrauma: issues in research, service and policy

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.

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).

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 impact of cognitive-communication difficulties following traumatic brain injury on the family; a qualitative, focus group study

Primary Objective: To identify how families experience cognitive-communication difficulties following Traumatic Brain Injury (TBI). Experiences of information, training and support for managing communication changes were also explored. Research Design: Qualitative focus group methodology using thematic analysis. Method: 15 family members of individuals with cognitive-communication difficulties following severe TBI participated in the study; four parents, six spouses, three siblings and two offspring. The majority of participants were female (80%, n = 12), with a mean age of 51 (range 19-71). Four focus groups were held with family members at 0-12 months, 12-36 months and 36+ months post-injury. The data were transcribed verbatim and analyzed using NVIVO 12.Results: Cognitive-communication difficulties were found to impact upon family functioning and psychological wellbeing for several years post-injury. Changes to social cognition, insight and the "filter switch" of the person following TBI were key areas of distress. Participants highlighted the need for information about communication changes to be provided at several time points post-injury. The need for peer support from other families with experience of cognitive-communication difficulties was also identified.Conclusion: Cognitive-communication difficulties impact upon family functioning for many years following injury with families continuing to have support needs for communication well beyond the acute rehabilitation stage.

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).

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.

Impact of self-instruction manual-based training of family caregivers of neurosurgery patients on their knowledge and care practices - A randomized controlled trial

Background:

Family caregivers of operated neurosurgery patients function as informal extensions of the health system. But they are untrained and unprepared for their new role. It has been felt that their problems related to care provision can be resolved by appropriate training.

Aim:

This study aimed to compare the impact of self-instruction manual-based training of family caregivers of operated neurosurgery patients on their knowledge regarding care provision and care practices.

Setting:

Tertiary care hospital setting located in North India.

Design:

Randomized controlled trial.

Materials and Methods:

A randomized controlled trial was done among the operated neurosurgery patients and their caregiver dyads (n = 90). They were randomly allocated to receive either self-instruction manual and one-to-one training (TP1) or self-instruction manual only (TP2). Block randomization method was used. Sequentially numbered sealed envelope was used for allocation concealment. Monthly follow-up was done for 3 months. The primary outcome measure was knowledge gain of the caregivers.

Statistical Analysis Used:

Chi-square test, Student's t-test, paired t-test, repeated measures analysis of variance, and Bonferroni's correction were used.

Results:

The attrition rate was 15.5%. Intention-to-treat analysis was followed. Caregivers in the TP1 group had significant knowledge gain (95% confidence interval of mean difference 9.4–14.5, P < 0.05). The number of caregivers who had followed correct caregiving practices was significantly more in the TP1 group.

Conclusion:

Training of caregivers by providing information along with one-to-one training is an effective strategy for improving the knowledge and skills of caregivers regarding care provision of the operated neurosurgery patients.

Relatives' strategies in subacute brain injury rehabilitation: The warrior, the observer and the hesitant

BACKGROUND

Relative involvement is crucial in rehabilitation when patients are incapable of being involved due to cognitive and functional dysfunction. However, studies have shown that this is complex because of differing understandings of the meaning of involvement as well as diverse needs to be involved.

AIMS AND OBJECTIVES

To explore the experience of the rehabilitation process from the perspectives of relatives of patients with a traumatic brain injury. The aim of the study was, through a theoretical-empirical analysis, to identify relatives' strategies and practices in the rehabilitation process as evidenced in meetings with providers.

DESIGN

A longitudinal study with a qualitative approach, drawing on the theory of Pierre Bourdieu.

METHODS

Data were generated using participant observation and semi-structured interviews. Participants were eleven relatives of patients with a severe traumatic brain injury, followed through in-patient rehabilitation varying from 9-12 weeks. Analysis was undertaken using both an inductive and deductive approach.

FINDINGS

Drawing on Bourdieu's concept of strategy, three relative positions were identified, the warrior, the observer and the hesitant. These positions illustrate how different relative positions and their related dispositions influence the strategies used by relatives of patients with a severe traumatic brain injury evidenced in how they act, participate and relate to both the patient and the providers during the course of rehabilitation.

CONCLUSIONS

Acknowledging the relatives' positions during the rehabilitation process enables better understanding and support of the relatives in the rehabilitation process to meet their (and thus the patients') diverse needs.

RELEVANCE TO CLINICAL PRACTICE

The findings have practical implications in informing how clinicians meet, interact, communicate and involve relatives of adult patients' with traumatic brain injury in decision-making during rehabilitation.

The Development of a New Computer Adaptive Test to Evaluate Anxiety in Caregivers of Individuals With Traumatic Brain Injury: TBI-CareQOL Caregiver-Specific Anxiety

OBJECTIVE

To design a new measure of caregiver-specific anxiety for use in caregivers of individuals with traumatic brain injury (TBI), the Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Caregiver-Specific Anxiety item bank.

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.

Objective and Subjective Burden of Informal Caregivers 4 Years After a Severe Traumatic Brain Injury: Results From the PariS-TBI Study

OBJECTIVE

Prospective assessment of informal caregiver (IC) burden 4 years after the traumatic brain injury of a relative.

SETTING

Longitudinal cohort study (metropolitan Paris, France).

PARTICIPANTS

Home dwelling adults (N = 98) with initially severe traumatic brain injury and their primary ICs.

MAIN OUTCOME MEASURES

Informal caregiver objective burden (Resource Utilization in Dementia measuring Informal Care Time [ICT]), subjective burden (Zarit Burden Inventory), monetary self-valuation of ICT (Willingness-to-pay, Willingness-to-accept).

RESULTS

Informal caregivers were women (81%) assisting men (80%) of mean age of 37 years. Fifty-five ICs reported no objective burden (ICT = 0) and no/low subjective burden (average Zarit Burden Inventory = 12.1). Forty-three ICs reported a major objective burden (average ICT = 5.6 h/d) and a moderate/severe subjective burden (average Zarit Burden Inventory = 30.3). In multivariate analyses, higher objective burden was associated with poorer Glasgow Outcome Scale-Extended scores, with more severe cognitive disorders (Neurobehavioral Rating Scale-revised) and with no coresidency status; higher subjective burden was associated with poorer Glasgow Outcome Scale-Extended scores, more Neurobehavioral Rating Scale-revised disorders, drug-alcohol abuse, and involvement in litigation. Economic valuation showed that on average, ICs did not value their ICT as free and preferred to pay a mean Willingness-to-pay = &OV0556;17 per hour to be replaced instead of being paid for providing care themselves (Willingness-to-accept = &OV0556;12).

CONCLUSION

Four years after a severe traumatic brain injury, 44% of ICs experienced a heavy multidimensional burden.

Traumatic brain injury: unmet support needs of caregivers and families in Florida

Sustaining a Traumatic Brain Injury results in familial strain due to the significant impact the injury has upon the role and function of individuals and their families at home and in the community. Using the Stress Process Model of Caregiving, a caregiver needs assessment survey was developed and conducted to better understand the needs of individuals with a Traumatic Brain Injury and their caregivers. Survey results indicate that caregivers experience many challenges including unmet needs in areas of relational supports such as maintaining relationships, long-term emotional and financial support for themselves and the survivor, and the need for a patient or caregiver advocate. Implications for future practice are presented.

Does problem-solving training for family caregivers benefit their care recipients with severe disabilities? A latent growth model of the Project CLUES randomized clinical trial

OBJECTIVE

To examine whether an individualized problem-solving intervention provided to family caregivers of persons with severe disabilities provides benefits to both caregivers and their care recipients.

DESIGN

Family caregivers were randomly assigned to an education-only control group or a problem-solving training (PST) intervention group. Participants received monthly contacts for 1 year.

PARTICIPANTS

Family caregivers (129 women, 18 men) and their care recipients (81 women, 66 men) consented to participate.

MAIN OUTCOME MEASURES

Caregivers completed the Social Problem-Solving Inventory-Revised, the Center for Epidemiological Studies-Depression scale, the Satisfaction with Life scale, and a measure of health complaints at baseline and in 3 additional assessments throughout the year. Care recipient depression was assessed with a short form of the Hamilton Depression Scale.

RESULTS

Latent growth modeling was used to analyze data from the dyads. Caregivers who received PST reported a significant decrease in depression over time, and they also displayed gains in constructive problem-solving abilities and decreases in dysfunctional problem-solving abilities. Care recipients displayed significant decreases in depression over time, and these decreases were significantly associated with decreases in caregiver depression in response to training.

CONCLUSIONS

PST significantly improved the problem-solving skills of community-residing caregivers and also lessened their depressive symptoms. Care recipients in the PST group also had reductions in depression over time, and it appears that decreases in caregiver depression may account for this effect.
