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).

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).

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).

Objective: To develop an item response theory (IRT)-calibrated, patient-reported outcome measure of subjective independence for individuals with traumatic brain injury (TBI)., Design: Large-scale item calibration field testing; confirmatory factor analysis (CFA) and graded response model IRT analyses., Setting: Five TBI Model System centers across the United States., Participants: Adults with complicated mild, moderate, or severe TBI (N=556)., Outcome Measures: Traumatic Brain Injury-Quality of Life (TBI-QOL) Independence item bank and the TBI-QOL Asking for Help scale., Results: A total of 556 individuals completed 44 items in the Independence item pool. Initial factor analyses indicated that items related to the idea of "asking for help" were measuring a different construct from other items in the pool. These 9 items were set aside. Twenty-two other items were removed because of bimodal distributions and/or low item-total correlations. CFA supported unidimensionality of the remaining Independence items. Graded response model IRT analysis was used to estimate slopes and thresholds for the final 13 Independence items. An 8-item fixed-length short form was also developed. The 9 Asking for Help items were analyzed separately. One misfitting item was deleted, and the final 8 items became a fixed-length IRT-calibrated scale. Reliability was high for both measures., Conclusions: The IRT-calibrated TBI-QOL Independence item bank and short form and TBI-QOL Asking for Help scale may be used to measure important issues for individuals with TBI in research and clinical applications., (Copyright © 2019 American Congress of Rehabilitation Medicine.

Objective: To develop a pain interference item bank, computer adaptive test (CAT), and short form for use by individuals with traumatic brain injury (TBI)., Design: Cross-sectional survey study., Setting: Five TBI Model Systems rehabilitation hospitals., Participants: Individuals with TBI (N=590)., Interventions: Not applicable., Outcome Measures: Traumatic Brain Injury-Quality of Life (TBI-QOL) Pain Interference item bank., Results: Confirmatory factor analysis provided evidence of a single underlying trait (χ 2 [740]=3254.030; P<.001; Comparative Fix Index=0.988; Tucker-Lewis Index=0.980; Root Mean Square Error of Approximation=0.076) and a graded response model (GRM) supported item fit of 40 Pain Interference items. Items did not exhibit differential item functioning or local item dependence. GRM calibration data were used to inform the selection of a 10-item static short form and to program a TBI-QOL Pain Interference CAT. Comparative analyses indicated excellent comparability and reliability across test administration formats., Conclusion: The 40-item TBI-QOL Pain Interference item bank demonstrated strong psychometric properties. End users can administer this measure as either a 10-item short form or CAT., (Copyright © 2019 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.)

Objective: To develop a set of composite scores that can be used for interpreting quality of life (QOL) after traumatic brain injury (TBI) using 9 of the patient-reported outcomes measures from the Traumatic Brain Injury Quality of Life (TBI-QOL) measurement system., Design: Participants completed 20 item banks from the TBI-QOL as part of a larger assessment. Composite index scores were created with normalized transformation with nonlinear area conversion using scores from 9 of the banks, and are expressed in index score units, with higher composite scores indicating better functioning. For descriptive purposes, associations among composites and individual banks were evaluated using regression, along with patterns of composite scores by injury severity groups using analysis of variance., Setting: Three medical centers in the United States., Participants: Community-dwelling adults (n=504) with a history of TBI., Interventions: Not applicable., Main Outcomes Measure: TBI-QOL., Results: Five composite indices were generated: global QOL, physical health, emotional health, cognitive health, and social health. Lookup tables are provided herein. Composite scores were highly intercorrelated (all r>.60, P<.0001), and individual TBI-QOL banks all correlate strongly with the global QOL composite in the expected direction (all r>.50, P<.0001)., Conclusion: Researchers and clinicians can use the TBI-QOL global QOL, physical health, emotional health, cognitive health, and social health composite scores to aggregate results from multiple TBI-QOL banks, which is anticipated to ease interpretation and reliability. This work additionally highlights the importance of considering nonphysical symptoms as outcomes variables for TBI research, as cognitive, social, and emotional domains were some of the most strongly correlated banks with the global QOL composite., (Copyright © 2018 American Congress of Rehabilitation Medicine.

Objective: To develop traumatic brain injury (TBI)-optimized versions of the Quality of Life in Neurological Disorders (Neuro-QoL) Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities item banks, evaluate the psychometric properties of the item banks developed for adults with TBI, develop short form and computer adaptive test (CAT) versions, and report information to facilitate research and clinical applications., Design: We used a mixed methods design to develop and evaluate Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities items. Focus groups defined the constructs, cognitive interviews guided item revisions, and confirmatory factor analysis and item response theory methods helped calibrate item banks and evaluate differential item functioning related to demographic and injury characteristics., Setting: Five TBI Model Systems centers in the United States., Participants: Community-dwelling adults with TBI (N=556)., Interventions: None., Outcome Measures: Traumatic Brain Injury-Quality of Life (TBI-QOL) Ability to Participate in Social Roles and Activities and TBI-QOL Satisfaction with Social Roles and Activities item banks., Results: Forty-five Ability to Participate in Social Roles and Activities and 41 Satisfaction with Social Roles and Activities items demonstrated good psychometric properties. Although some of the items are new, most were drawn from analogous banks in the Neuro-QoL measurement system. Consequently, the 2 TBI-QOL item banks were linked to the Neuro-QoL metric, and scores are comparable with the general population. All CAT and short forms correlated highly (>0.90) with the full item banks and demonstrate comparable construct coverage and measurement error., Conclusion: The TBI-QOL Ability to Participate in Social Roles and Activities and TBI-QOL Satisfaction with Social Roles and Activities item banks are TBI-optimized versions of the Neuro-QoL Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities item banks and demonstrate excellent measurement properties in individuals with TBI. These measures, particularly in CAT or short form format, are suitable for efficient and precise measurement of social outcomes in clinical and research applications., (Copyright © 2019 American Congress of Rehabilitation Medicine.

Objective: To link scores on commonly used measures of anxiety (7-item Generalized Anxiety Disorder Scale; GAD-7) and depression (9-item Patient Health Questionnaire; PHQ-9) to the Traumatic Brain Injury Quality of Life (TBI-QOL) measurement system., Setting: 5 Traumatic Brain Injury Model Systems., Participants: A total of 385 individuals with traumatic brain injury (TBI) (31% complicated mild; 14% moderate; and 54% severe)., Design: Observational cohort., Main Measures: GAD-7, PHQ-9, TBI-QOL Anxiety v1.0 and TBI-QOL Depression v1.0., Results: Item response theory-based linking methods were used to create crosswalk tables that convert scores on the GAD-7 to the TBI-QOL Anxiety metric and scores on the PHQ-9 to the TBI-QOL Depression metric. Comparisons between actual and crosswalked scores suggest that the linkages were successful and are appropriate for group-level analysis. Linking functions closely mirror crosswalks between the GAD-7/PHQ-9 and the Patient-Reported Outcomes Measurement Information System (PROMIS), suggesting that general population linkages are similar to those from a TBI sample., Conclusion: Researchers and clinicians can use the crosswalk tables to transform scores on the GAD-7 and the PHQ-9 to the TBI-QOL metric for group-level analyses.

Objective: To develop and calibrate new patient-reported outcome measures of cognitive concerns for individuals with traumatic brain injury (TBI)., Setting: Five TBI model systems rehabilitation centers in the United States., Participants: Adults with medically confirmed history of TBI., Design: Cross-sectional survey in interview format., Main Measures: Traumatic Brain Injury-Quality of Life (TBI-QOL) Executive Function and TBI-QOL Cognition-General Concerns item banks., Results: A total of 569 adults with complicated-mild, moderate, or severe TBI completed preliminary item pools, which included 65 Executive Function items and 56 Cognition-General Concerns items. Confirmatory factor analysis supported the retention of 37 Executive Function and 39 Cognition-General Concerns items. Samejima's graded response model was used to estimate item parameters for associated computer adaptive test administrations, and informed the selection of corresponding static short forms. Data from an independent sample of 77 adults with complicated-mild, moderate, or severe TBI supported the test-retest reliability of these newly developed measures., Conclusion: The TBI-QOL Executive Function and Cognition-General Concerns item banks provide researchers and clinicians with reliable tools for assessing patient-reported post-TBI cognitive difficulties as part of the comprehensive TBI-QOL measurement system.

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.

Objective: To develop a traumatic brain injury (TBI)-specific, item response theory (IRT)-calibrated Fatigue item bank, short form, and computer adaptive test (CAT) as part of the Traumatic Brain Injury-Quality of Life (TBI-QOL) measurement system., Setting: Five TBI Model Systems rehabilitation centers in the US PARTICIPANTS:: Adults with complicated mild, moderate, or severe TBI confirmed by medical record review., Design: Cross-sectional field testing via phone or in-person interview., Main Measures: TBI-QOL Fatigue item bank, short form, and CAT., Results: A total of 590 adults with TBI completed 95 preliminary fatigue items, including 86 items from the Patient-Reported Outcomes Measurement Information System (PROMIS) and 9 items from the Quality of Life in Neurological Disorders (Neuro-QOL) system. Through 4 iterations of factor analysis, 22 items were deleted for reasons such as local item dependence, misfit, and low item-total correlations. Graded response model IRT analyses were conducted on the 73-item set, and Stocking-Lord equating was used to transform the item parameters to the PROMIS (general population) metric. A short form and CAT, which demonstrate similar reliability to the full item bank, were developed. Test-retest reliability of the CAT was established in an independent sample (Pearson's r and intraclass correlation coefficient = 0.82 [95% confidence interval: 0.72-0.88])., Conclusions: The TBI-QOL Fatigue item bank, short form, and CAT provide rehabilitation researchers and clinicians with TBI-optimized tools for assessment of the patient-reported experience and impact of fatigue on individuals with TBI.

Objective: To develop an item response theory (IRT)-based patient-reported outcome measure of functional communication for adults with traumatic brain injury (TBI)., Setting: Five medical centers that were TBI Model Systems sites., Participants: A total of 569 adults with TBI (28% complicated-mild; 13% moderate; and 58% severe)., Design: Grounded theory-based qualitative item development, large-scale item calibration testing, confirmatory factor analyses, psychometric analyses with graded response model IRT., Main Measure: Traumatic Brain Injury-Quality of Life (TBI-QOL) Communication Item Bank, version 1.0., Results: From an initial pool of 48 items, 31 items were retained in the final instrument based on adequate fit to a unidimensional model and absence of bias across several demographic and clinical subgroupings. The TBI-QOL Communication Item Bank demonstrated excellent score precision (reliability ≥ 0.95) across a wide range of communication impairment levels, particularly for individuals with more severe difficulties. The TBI-QOL Communication Item Bank is available as a full item bank, fixed-length short form, and as a computerized adaptive test., Conclusions: The TBI-QOL Communication Item Bank permits precise measurement of patient-reported functional communication after TBI. Future development will validate the instrument against performance-based, clinician-reported, and surrogate-reported assessments.

Objective: To develop, calibrate, and evaluate the test-retest reliability of a new patient-reported outcome measure of headache pain relevant for individuals with traumatic brain injury (TBI)., Setting: Six TBI Model Systems rehabilitation centers in the United States., Participants: Adults with medically confirmed documentation of TBI., Design: Cross-sectional calibration field testing and test-retest reliability analyses., Main Measures: Traumatic Brain Injury-Quality of Life Headache Pain item bank., Results: Thirteen headache pain items were calibrated as a unidimensional measure using data from 590 participants. The new measure was reliable (α = .98; item-total correlation range: 0.71-0.91). Item parameter estimates were estimated using Samejima's Graded Response Model and a 10-item calibrated short form was created. Simulation testing confirmed that both the computer-adaptive test and the short-form administrations were equivalent to the full item bank. One- to-2-week test-retest reliability of the computer-adaptive test was high (Pearson r and intraclass correlation coefficients = 0.81). Approximately two-thirds of the sample reported at least 1 headache symptom., Conclusion: The Traumatic Brain Injury-Quality of Life Headache Pain item bank and short form provide researchers and clinicians with reliable measures of the subjective experience of headache symptoms for individuals with a history of TBI.

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., (Copyright © 2018 American Congress of Rehabilitation Medicine.

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., (Copyright © 2018 American Congress of Rehabilitation Medicine.

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., (Copyright © 2018 American Congress of Rehabilitation Medicine.

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., (Copyright © 2018 American Congress of Rehabilitation Medicine.

Purpose The purpose of this study was to evaluate the internal consistency and construct validity of the Traumatic Brain Injury Quality of Life Communication Item Bank (TBI-QOL COM) short form as a parent-proxy report measure. The TBI-QOL COM is a patient-reported outcome measure of functional communication originally developed as a self-report measure for adults with traumatic brain injury (TBI), but it may also be valid as a parent-proxy report measure for children who have sustained TBI. Method One hundred twenty-nine parent-proxy raters completed the TBI-QOL COM short form 6 months postinjury as a secondary aim of a multisite study of pediatric TBI outcomes. The respondents' children with TBI were between 8 and 18 years old ( M age = 13.2 years old) at the time of injury, and the proportion of TBI severity mirrored national trends (73% complicated-mild; 27% moderate or severe). Results The parent-proxy report version of the TBI-QOL COM displayed strong internal consistency (ordinal α = .93). It also displayed evidence of known-groups validity by virtue of more severe injuries associated with more abnormal scores. The instrument also showed evidence of convergent and discriminant validity by displaying a pattern of correlations with other constructs according to their conceptual relatedness to functional communication. Conclusions This preliminary psychometric investigation of the TBI-QOL COM supports the further development of a parent report version of the instrument. Future development of the TBI-QOL COM with this population may include expanding the content of the item bank and developing calibrations specifically for parent-proxy raters.

Purpose/objective: To compare and contrast how individuals with traumatic brain injury (TBI) are classified (positive or negative screen) by different cut-offs on two self-report measures of depressive symptoms: the PHQ-9, which assesses somatic symptoms, and the TBI-QOL Depression item bank, which does not. Research Method/Design: Three hundred eighty-five individuals with TBI were recruited from six rehabilitation hospitals in the U.S. as part of the calibration data collection for the TBI-QOL patient-reported outcome measurement system., Results: The TBI-QOL and PHQ-9 total scores correlated strongly (disattenuated r = .83). The correlation was even stronger (disattenuated r = .92) when the four PHQ-9 somatic items were removed from the total score. When the PHQ-9 was scored traditionally, the rate of agreement was approximately 80-85% using standard cut-offs for each scale. Depending on the cut-off score, 23-26% of participants screened positive on the PHQ-9, whereas 9-38% screened positive on the TBI-QOL Depression. Individuals who screened positive on the PHQ-9 alone reported more somatic symptoms than those who screened positive on the TBI-QOL alone. Individuals who screened positive on the TBI-QOL alone were at slightly greater risk for other negative psychological functioning than individuals who screened positive on the PHQ-9 alone., Conclusions/implications: The PHQ-9 and TBI-QOL Depression performed similarly in screening for depressive symptoms among individuals with TBI. The PHQ-9 identified more individuals with somatic symptoms, which may overlap with other medical issues, whereas the TBI-QOL Depression instrument identified more individuals who reported other forms of emotional distress.

Objectives: To evaluate the psychometric properties of the Spinal Cord Injury-Functional Index/Assistive Technology (SCI-FI/AT) short forms (SFs) in the domains of basic mobility, self-care, fine motor function, and ambulation based on internal consistency; correlations between SFs and full item banks, and a 10-item computerized adaptive test (CAT) version; magnitude of ceiling and floor effects; and measurement precision across a broad range of function in a sample of adults with spinal cord injury (SCI)., Design: Cross-sectional cohort study., Setting: Nine national Spinal Cord Injury Model Systems programs., Participants: A sample of adults with traumatic SCI (N=460) stratified by level of injury (paraplegia/tetraplegia), completeness of injury, and time since SCI., Interventions: Not applicable., Main Outcome Measures: SCI-FI/AT full item bank, 10-item CAT, and SFs (with separate Self-Care and Fine Motor Function SFs for persons with tetraplegia and paraplegia)., Results: The SCI-FI/AT SFs demonstrated very good internal consistency, group-level reliability, and excellent correlations between SFs and scores based on the CAT version and the total item bank. Ceiling and floor effects are acceptable (except for unacceptable ceiling effects for persons with paraplegia on the Self-Care and Fine Motor Function SFs). The test information functions are excellent across a broad range of functioning typical of persons with paraplegia and tetraplegia., Conclusions: Clinicians and researchers should consider using the SCI-FI/AT SFs to assess functioning with the use of assistive technology when CAT applications are not available., (Copyright © 2016 American Congress of Rehabilitation Medicine.

Objective: To use a patient-centered approach or participatory action research design combined with advanced psychometrics to develop a comprehensive patient-reported outcomes (PRO) measurement system specifically for individuals with traumatic brain injury (TBI). This TBI Quality-of-Life (TBI-QOL) measurement system expands the work of other large PRO measurement initiatives, that is, the Patient-Reported Outcomes Measurement Information System and the Neurology Quality-of-Life measurement initiative., Setting: Five TBI Model Systems centers across the United States., Participants: Adults with TBI., Design: Classical and modern test development methodologies were used. Qualitative input was obtained from individuals with TBI, TBI clinicians, and caregivers of individuals with TBI through multiple methods, including focus groups, individual interviews, patient consultation, and cognitive debriefing interviews. Item pools were field tested in a large multisite sample (n = 675) and calibrated using item response theory methods., Main Outcomes Measures: Twenty-two TBI-QOL item banks/scales., Results: The TBI-QOL consists of 20 independent calibrated item banks and 2 uncalibrated scales that measure physical, emotional, cognitive, and social aspects of health-related quality of life., Conclusions: The TBI-QOL measurement system has potential as a common data element in TBI research and to enhance collection of health-related quality-of-life and PRO data in rehabilitation research and clinical settings.

Objective: To investigate unique factors that affect health-related quality of life (QOL) in individuals with military deployment-related traumatic brain injury (MDR-TBI) and to develop appropriate assessment tools, consistent with the TBI-QOL/PROMIS/Neuro-QOL systems., Participants: Three focus groups from each of the 4 Veterans Administration (VA) Polytrauma Rehabilitation Centers, consisting of 20 veterans with mild to severe MDR-TBI, and 36 VA providers were involved in early stage of new item banks development. The item banks were field tested in a sample (N = 485) of veterans enrolled in VA and diagnosed with an MDR-TBI., Design: Focus groups and survey., Outcome Measures: Developed item banks and short forms for Guilt, Posttraumatic Stress Disorder/Trauma, and Military-Related Loss., Results: Three new item banks representing unique domains of MDR-TBI health outcomes were created: 15 new Posttraumatic Stress Disorder items plus 16 SCI-QOL legacy Trauma items, 37 new Military-Related Loss items plus 18 TBI-QOL legacy Grief/Loss items, and 33 new Guilt items. Exploratory and confirmatory factor analyses plus bifactor analysis of the items supported sufficient unidimensionality of the new item pools. Convergent and discriminant analyses results, as well as known group comparisons, provided initial support for the validity and clinical utility of the new item response theory-calibrated item banks and their short forms., Conclusion: This work provides a unique opportunity to identify issues specific to individuals with MDR-TBI and ensure that they are captured in QOL assessment, thus extending the existing TBI-QOL measurement system.

Objective: To develop a calibrated item bank and computer adaptive test to assess anxiety symptoms in individuals with spinal cord injury (SCI), transform scores to the Patient Reported Outcomes Measurement Information System (PROMIS) metric, and create a statistical linkage with the Generalized Anxiety Disorder (GAD)-7, a widely used anxiety measure., Design: Grounded-theory based qualitative item development methods; large-scale item calibration field testing; confirmatory factor analysis; graded response model item response theory analyses; statistical linking techniques to transform scores to a PROMIS metric; and linkage with the GAD-7. Setting Five SCI Model System centers and one Department of Veterans Affairs medical center in the United States. Participants Adults with traumatic SCI., Main Outcome Measures: Spinal Cord Injury-Quality of Life (SCI-QOL) Anxiety Item Bank, Results: Seven hundred sixteen individuals with traumatic SCI completed 38 items assessing anxiety, 17 of which were PROMIS items. After 13 items (including 2 PROMIS items) were removed, factor analyses confirmed unidimensionality. Item response theory analyses were used to estimate slopes and thresholds for the final 25 items (15 from PROMIS). The observed Pearson correlation between the SCI-QOL Anxiety and GAD-7 scores was 0.67., Conclusions: The SCI-QOL Anxiety item bank demonstrates excellent psychometric properties and is available as a computer adaptive test or short form for research and clinical applications. SCI-QOL Anxiety scores have been transformed to the PROMIS metric and we provide a method to link SCI-QOL Anxiety scores with those of the GAD-7.

Objective: To develop a calibrated item bank and computer adaptive test (CAT) to assess the effects of stigma on health-related quality of life in individuals with spinal cord injury (SCI)., Design: Grounded-theory based qualitative item development methods, large-scale item calibration field testing, confirmatory factor analysis, and item response theory (IRT)-based psychometric analyses., Setting: Five SCI Model System centers and one Department of Veterans Affairs medical center in the United States., Participants: Adults with traumatic SCI., Main Outcome Measures: SCI-QOL Stigma Item Bank, Results: A sample of 611 individuals with traumatic SCI completed 30 items assessing SCI-related stigma. After 7 items were iteratively removed, factor analyses confirmed a unidimensional pool of items. Graded Response Model IRT analyses were used to estimate slopes and thresholds for the final 23 items., Conclusions: The SCI-QOL Stigma item bank is unique not only in the assessment of SCI-related stigma but also in the inclusion of individuals with SCI in all phases of its development. Use of confirmatory factor analytic and IRT methods provide flexibility and precision of measurement. The item bank may be administered as a CAT or as a 10-item fixed-length short form and can be used for research and clinical applications.

Objective: To develop a comprehensive, psychometrically sound, and conceptually grounded patient reported outcomes (PRO) measurement system for individuals with spinal cord injury (SCI)., Methods: Individual interviews (n=44) and focus groups (n=65 individuals with SCI and n=42 SCI clinicians) were used to select key domains for inclusion and to develop PRO items. Verbatim items from other cutting-edge measurement systems (i.e. PROMIS, Neuro-QOL) were included to facilitate linkage and cross-population comparison. Items were field tested in a large sample of individuals with traumatic SCI (n=877). Dimensionality was assessed with confirmatory factor analysis. Local item dependence and differential item functioning were assessed, and items were calibrated using the item response theory (IRT) graded response model. Finally, computer adaptive tests (CATs) and short forms were administered in a new sample (n=245) to assess test-retest reliability and stability., Participants and Procedures: A calibration sample of 877 individuals with traumatic SCI across five SCI Model Systems sites and one Department of Veterans Affairs medical center completed SCI-QOL items in interview format., Results: We developed 14 unidimensional calibrated item banks and 3 calibrated scales across physical, emotional, and social health domains. When combined with the five Spinal Cord Injury--Functional Index physical function banks, the final SCI-QOL system consists of 22 IRT-calibrated item banks/scales. Item banks may be administered as CATs or short forms. Scales may be administered in a fixed-length format only., Conclusions: The SCI-QOL measurement system provides SCI researchers and clinicians with a comprehensive, relevant and psychometrically robust system for measurement of physical-medical, physical-functional, emotional, and social outcomes. All SCI-QOL instruments are freely available on Assessment CenterSM.

Objective: To describe the development and psychometric properties of the SCI-QOL Psychological Trauma item bank and short form., Design: Using a mixed-methods design, we developed and tested a Psychological Trauma item bank with patient and provider focus groups, cognitive interviews, and item response theory based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision., Setting: We tested a 31-item pool at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Veterans Administration hospital., Participants: A total of 716 individuals with SCI completed the trauma items, Results: The 31 items fit a unidimensional model (CFI=0.952; RMSEA=0.061) and demonstrated good precision (theta range between 0.6 and 2.5). Nine items demonstrated negligible DIF with little impact on score estimates. The final calibrated item bank contains 19 items, Conclusion: The SCI-QOL Psychological Trauma item bank is a psychometrically robust measurement tool from which a short form and a computer adaptive test (CAT) version are available.

Objective: To describe the development and psychometric properties of the Spinal Cord Injury--Quality of Life (SCI-QOL) Resilience item bank and short form., Design: Using a mixed-methods design, we developed and tested a resilience item bank through the use of focus groups with individuals with SCI and clinicians with expertise in SCI, cognitive interviews, and item-response theory based analytic approaches, including tests of model fit and differential item functioning (DIF)., Setting: We tested a 32-item pool at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs medical center., Participants: A total of 717 individuals with SCI completed the Resilience items., Results: A unidimensional model was observed (CFI=0.968; RMSEA=0.074) and measurement precision was good (theta range between -3.1 and 0.9). Ten items were flagged for DIF, however, after examination of effect sizes we found this to be negligible with little practical impact on score estimates. The final calibrated item bank resulted in 21 retained items., Conclusion: This study indicates that the SCI-QOL Resilience item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available.

Objective: To describe the development and psychometric properties of the Spinal Cord Injury-Quality of Life (SCI-QOL) Self-esteem item bank., Design: Using a mixed-methods design, we developed and tested a self-esteem item bank through the use of focus groups with individuals with SCI and clinicians with expertise in SCI, cognitive interviews, and item-response theory-(IRT) based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision., Setting: We tested a pool of 30 items at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital, and the James J. Peters/Bronx Department of Veterans Affairs hospital., Participants: A total of 717 individuals with SCI completed the self-esteem items., Results: A unidimensional model was observed (CFI=0.946; RMSEA=0.087) and measurement precision was good (theta range between -2.7 and 0.7). Eleven items were flagged for DIF; however, effect sizes were negligible with little practical impact on score estimates. The final calibrated item bank resulted in 23 retained items., Conclusion: This study indicates that the SCI-QOL Self-esteem item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available.

Objective: To develop an item response theory (IRT)-calibrated spinal cord injury (SCI)-specific Positive Affect and Well-being (PAWB) item bank with flexible options for administration., Design: Qualitative feedback from patient and provider focus groups was used to expand on the Neurological Disorders and Quality of Life (Neuro-QOL) positive affect & well-being item bank for use in SCI. New items were created and revised based on expert review and patient feedback and were then field tested. Analyses included confirmatory factor analysis, graded response IRT modeling and evaluation of differential item functioning (DIF)., Setting: We tested a 32-item pool at several rehabilitation centers across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs hospital., Participants: A total of 717 individuals with SCI answered the PAWB questions., Results: A unidimensional model was observed (Confirmatory Fit Index=0.947; Root Mean Square Error of Approximation=0.094) and measurement precision was good (reliability in theta of -2.9 to 1.2 is roughly equivalent to classical reliability of 0.95 or above). Twelve items were flagged for DIF, however, after examination of effect sizes, the DIF was determined to be negligible and would have little practical impact on score estimates. The final calibrated item bank resulted in 28 retained items, Conclusions: This study indicates that the Spinal Cord Injury--Quality of Life PAWB bank represents a psychometrically robust measurement tool. Short form items are also suggested and a computer adaptive test is available.

Objective: To develop a spinal cord injury (SCI)-focused version of PROMIS and Neuro-QOL social domain item banks; evaluate the psychometric properties of items developed for adults with SCI; and report information to facilitate clinical and research use., Design: We used a mixed-methods design to develop and evaluate Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities items. Focus groups helped define the constructs; cognitive interviews helped revise items; and confirmatory factor analysis and item response theory methods helped calibrate item banks and evaluate differential item functioning related to demographic and injury characteristics., Setting: Five SCI Model System sites and one Veterans Administration medical center., Participants: The calibration sample consisted of 641 individuals; a reliability sample consisted of 245 individuals residing in the community., Results: A subset of 27 Ability to Participate and 35 Satisfaction items demonstrated good measurement properties and negligible differential item functioning related to demographic and injury characteristics. The SCI-specific measures correlate strongly with the PROMIS and Neuro-QOL versions. Ten item short forms correlate >0.96 with the full banks. Variable-length CATs with a minimum of 4 items, variable-length CATs with a minimum of 8 items, fixed-length CATs of 10 items, and the 10-item short forms demonstrate construct coverage and measurement error that is comparable to the full item bank., Conclusion: The Ability to Participate and Satisfaction with Social Roles and Activities CATs and short forms demonstrate excellent psychometric properties and are suitable for clinical and research applications.

Purpose: The Patient-Reported Outcomes Measurement Information System (PROMIS(®)) provides adult and pediatric self-report measures of health-related quality of life designed for use across medical conditions and the general population. The purpose of this study was to examine the feasibility and validity of the PROMIS(®) Pediatric Short Form and computer-adaptive test (CAT) mobility measures in children with cerebral palsy (CP)., Methods: Eighty-two children with CP completed self-report (PROMIS(®) Mobility Short Form, PROMIS(®) Mobility CAT, Pediatric Quality of Life Inventory™) and performance-based assessments of mobility (Timed Up and Go, Gross Motor Function Measure). Parents provided three proxy reports of child mobility (Pediatric Outcomes Data Collection Instrument, Functional Assessment Questionnaire, Shriners Hospitals for Children CP-CAT). Validity of PROMIS(®) instruments was examined through correlations with other measures and "known groups" analyses determined by Gross Motor Function Classification System (GMFCS)., Results: On average, the PROMIS(®) CAT required less than seven items and 2 minutes to administer. Both PROMIS(®) measures showed moderate to high correlations with child- and parent-proxy report of child mobility; correlations with performance-based measure were small for the PROMIS(®) Short Form and non-significant for the PROMIS(®) CAT. All measures except for the PROMIS(®) CAT were able to distinguish between GMFCS categories., Conclusions: Results support the convergent and discriminant validity of the pediatric PROMIS(®) Mobility Short Form in children with CP. The PROMIS(®) Mobility CAT correlates well with child report and parent report of mobility but not with performance-based measures and does not differentiate between known mobility groups.

The importance of activities and community participation for persons with spinal cord injury (SCI) has been recognized for decades and yet theoretical and empirical advances have been limited. This report summarizes the recommendations for researchers on the topic of measuring activity and participation among persons with SCI formulated by the Spinal Cord Injury workgroup at the State-of-the-Art Conference on Outcome Measures in Rehabilitation held in January 2010. Activity and participation were defined as independent constructs ideally measured in reference to personal values and environmental influences. Measures of activity, participation, and factors influencing activity and participation are reviewed and critiqued. Gaps in available measures are described, measures in development are discussed, and suggestions for future research are made.

To provide reliability and validity data to support the clinical utility of Economic Quality of Life Measure (Econ-QOL) scores in caregivers of civilians and service members/veterans with traumatic brain injury (TBI). Cross-sectional survey study. Three academic medical centers and a Veterans Affairs treatment facility. 376 caregivers of civilians (n=213) and service members/veterans (n=163) with TBI (N=376). N/A. Econ-QOL and several patient-reported outcome measures (Traumatic Brain Injury Caregiver Quality of Life Caregiver-Specific Anxiety and Caregiver Strain, Patient-Reported Outcomes Measurement Information System sleep-related impairment, Neurological Quality of Life Measurement System positive affect and well-being) and measures of financial status (self-reported income). Internal consistency reliability of the Econ-QOL Short Form scores were excellent (all Cronbach's alphas ≥.92). There were no floor or ceiling effects for scores. There was evidence of convergent and discriminant validity, with the Econ-QOL scores having the strongest relationships with self-reported income (convergent validity evidence) and weak relationships with the other measures (discriminant validity evidence). Individuals with scores that were "below or possibly below" the poverty line (according to 2016 federal government poverty level thresholds) reported worse economic quality of life relative to those individuals who were definitely above the poverty line, supporting known-groups validity. This article establishes the clinical utility of scores on the Econ-QOL Short Form in caregivers of persons with TBI and provides evidence that it is valid and appropriate to use such scores not only in a variety of different disability populations (eg, spinal cord injury, stroke) but also in caregivers.

Abstract Objective To investigate the association of the sociocultural variables race/ethnicity, education, and poverty level to caregivers' positive and negative appraisals following traumatic brain injury. Design Survey. Setting Community. Participants Caregivers (N=344; 216 white; 69 black; 39 Hispanic) of persons with complicated mild to severe TBI at least 1-year postinjury. Intervention Not applicable. Main Outcome Measures Modified Caregiver Appraisal Scale (M-CAS); Zarit Burden Interview (ZBI). Results Black caregivers reported lower levels of perceived burden on both the M-CAS and the ZBI. Black and Hispanic caregivers reported more traditional caregiver ideology (caregiving as a responsibility) than did whites. Greater poverty was associated with higher burden on the M-CAS, lower caregiver satisfaction, and less mastery. Higher education was associated with higher burden on the ZBI and with lower caregiver mastery. Conclusions Treatment professionals should be culturally sensitive to the different perspectives that caregivers may have based on sociocultural factors. Sociocultural factors should be considered in research investigating caregiver outcomes, including appraisals. [ABSTRACT FROM AUTHOR]
