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).

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 (ß = -0.82, p = .08); the strongest predictor of sleep-related impairment of caregivers of SMVs was self-reported anger of the PwTBI (ß = 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.

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).

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.

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).

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).

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).

Using information from the electronic health record to improve measurement of unemployment in service members and veterans with mTBI and post-deployment stress.

OBJECTIVE: The purpose of this pilot study is 1) to develop an annotation schema and a training set of annotated notes to support the future development of a natural language processing (NLP) system to automatically extract employment information, and 2) to determine if information about employment status, goals and work-related challenges reported by service members and Veterans with mild traumatic brain injury (mTBI) and post-deployment stress can be identified in the Electronic Health Record (EHR). DESIGN: Retrospective cohort study using data from selected progress notes stored in the EHR. SETTING: Post-deployment Rehabilitation and Evaluation Program (PREP), an in-patient rehabilitation program for Veterans with TBI at the James A. Haley Veterans' Hospital in Tampa, Florida. PARTICIPANTS: Service members and Veterans with TBI who participated in the PREP program (N = 60). MAIN OUTCOME MEASURES: Documentation of employment status, goals, and work-related challenges reported by service members and recorded in the EHR. RESULTS: Two hundred notes were examined and unique vocational information was found indicating a variety of self-reported employment challenges. Current employment status and future vocational goals along with information about cognitive, physical, and behavioral symptoms that may affect return-to-work were extracted from the EHR. The annotation schema developed for this study provides an excellent tool upon which NLP studies can be developed. CONCLUSIONS: Information related to employment status and vocational history is stored in text notes in the EHR system. Information stored in text does not lend itself to easy extraction or summarization for research and rehabilitation planning purposes. Development of NLP systems to automatically extract text-based employment information provides data that may improve the understanding and measurement of employment in this important cohort.

Descriptive characteristics and rehabilitation outcomes in active duty military personnel and veterans with disorders of consciousness with combat- and noncombat-related brain injury.

OBJECTIVE: To report the injury and demographic characteristics, medical course, and rehabilitation outcome for a consecutive series of veterans and active duty military personnel with combat- and noncombat-related brain injury and disorder of consciousness (DOC) at the time of rehabilitation admission. DESIGN: Retrospective study. SETTING: Rehabilitation center. PARTICIPANTS: From January 2004 to October 2009, persons (N=1654) were admitted to the Polytrauma Rehabilitation System of Care. This study focused on the N=122 persons admitted with a DOC. Participants with a DOC were primarily men (96%), on active duty (82%), ≥12 years of education, and a median age of 25. Brain injury etiologies included mixed blast trauma (24%), penetrating (8%), other trauma (56%), and nontrauma (13%). Median initial Glasgow Coma Scale score was 3, and rehabilitation admission Glasgow Coma Scale score was 8. Individuals were admitted for acute neurorehabilitation approximately 51 days postinjury with a median rehabilitation length of stay of 132 days. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Recovery of consciousness and the FIM instrument. RESULTS: Most participants emerged to regain consciousness during neurorehabilitation (64%). Average gains ± SD on the FIM cognitive and motor subscales were 19 ± 25 and 7 ± 8, respectively. Common medical complications included spasticity (70%), dysautonomia (34%), seizure occurrence (30%), and intracranial infection (22%). Differential outcomes were observed across etiologies, particularly for those with blast-related brain injury etiology. CONCLUSIONS: Despite complex comorbidities, optimistic outcomes were observed. Individuals with severe head injury because of blast-related etiologies have different outcomes and comorbidities observed. Health-services research with a focus on prevention of comorbidities is needed to inform optimal models of care, particularly for combat injured soldiers with blast-related injuries.

Pain among veterans of Operations Enduring Freedom and Iraqi Freedom.

OBJECTIVE: Pain is one of the most frequently reported symptoms by veterans returning from recent overseas military actions. The purpose of the current study was to obtain a preliminary estimate of the prevalence and severity of pain among veterans of Operations Enduring Freedom and Iraqi Freedom (OEF/OIF; N=970). The demographic, etiologic, and diagnostic characteristics of 100 veterans with moderate to severe chronic pain conditions were examined in order to provide a description of this new group of pain patients. DESIGN: This was a historical cohort study that utilized electronic medical record review for all data collection. PATIENTS: All registered OEF/OIF veterans seeking treatment at a Southeastern Veterans' Affairs medical center were included in the initial cohort. In order to describe the characteristics of those with clinically significant pain, 100 veterans were randomly sampled from the subset of patients who reported moderate to severe chronic pain intensity during a medical visit (N=219). RESULTS: Approximately 47% of veterans whose charts included pain score documentation (N=793) reported at least a mild level of current pain. Moderate to severe pain intensity was recorded for 28% (N=219) of those in the initial cohort with pain scores. Diagnoses of musculoskeletal and connective tissue disorders were recorded for 82% of those with chronic conditions (i.e., duration>or=1 month). CONCLUSIONS: The results of this preliminary study suggest that a substantial percentage of OEF/OIF veterans will experience clinically significant pain following their military service.

Mechanism-of-injury approach to evaluating patients with blast-related polytrauma.

Civilians and military personnel alike are increasingly being exposed to explosives in war zones and other regions of political conflict and, consequently, they are suffering associated blast-related polytrauma (multiple complex injuries). Although acute, emergency-based medical care for patients with blast-related trauma has been well described, postacute clinical management--which is of greatest interest to primary care physicians and rehabilitation specialists--has not been well discussed or researched. The authors offer a description of the common injuries seen in patients with blast-related polytrauma, as well as a conceptual model of a potential evaluation and treatment strategy in the postacute setting. Although medical evaluation of a patient typically proceeds in a sequential manner based on primary symptoms, the authors advocate a parallel approach to patient evaluation based on mechanism (cause) of injury. Such an approach relies on knowledge of the typical physical and psychological sequelae associated with a particular mechanism of injury to guide patient assessment and treatment. The authors highlight the mechanism-of-injury approach used with patients who have blast-related polytrauma at the Veterans Health Administration's (VHA) Veterans Affairs Medical Center in Tampa, Fla, site of one of the VHA's four Polytrauma Rehabilitation Centers.

Depression and the adolescent with type 1 diabetes: the covert comorbidity.

Diabetes and depression have become increasingly linked. The incidence of depression in the adolescent diabetic population is especially concerning. The purpose of this article is to raise awareness of the association between diabetes and depression particularly in the adolescent population. It also discusses treatment techniques for the same population. Several treatment techniques have proved successful in this population. Psychiatric nurse practitioners and advanced practiced nurses are poised to implement these treatments and interventions.
