RESUMO
BACKGROUND: Housing security is a key social determinant of behavior related to health outcomes. OBJECTIVE: The purpose of this study was to develop a new patient-reported outcome measure that evaluates aspects of housing security for use in the Re-Engineered Discharge for Diabetes-Computer Adaptive Test (REDD-CAT) measurement system. DESIGN: Qualitative data, literature reviews, and cross-sectional survey study. PARTICIPANTS: A total of 225 people with T2DM provided responses to the items in this item pool. MAIN MEASURES: A new item pool that evaluates important aspects of housing security was developed using stakeholder data from focus groups of persons with T2DM. KEY RESULTS: For the Housing Affordability scale, factor analysis (both exploratory and confirmatory) supported the retention of six items. Of these items, none exhibited sparse cells or problems with monotonicity; no items were deleted due to low item-adjusted total score correlations. For the six affordability items, a constrained graded response model indicated no items exhibited misfit; thus, all were retained. No items indicated differential item functioning (examined for age, sex, education, race, and socioeconomic status). Thus, the final Affordability item bank comprised six items. A Housing Safety index (three items) and a Home Features index (eight items) were also developed. Reliability (i.e., internal consistency and test-retest reliability) and validity (i.e., convergent, discriminant, and known-groups) of the new measures were also supported. CONCLUSIONS: The REDD-CAT Housing Security Measure provides a reliable and valid assessment of housing affordability, safety, and home features in people with type 2 diabetes mellitus. Future work is needed to establish the clinical utility of this measure in other clinical populations.

PURPOSE: To develop a new computer adaptive test that evaluates important aspects of medication adherence for persons with type 2 diabetes mellitus. METHODS: Two hundred and twenty-five people with type 2 diabetes mellitus completed 41 items related to medication adherence. RESULTS: Exploratory analysis supported the essential unidimensionality of the initial item pool. Five items were deleted due to low item-adjusted total score correlations (resulting in 36 items). Confirmatory factor analysis supported the retention of 27 items. A graded response model identified no items for exclusion, based on misfit. No items were flagged for meaningful differential item functioning (DIF). The final item bank is comprised of 27 items; an associated 6-item short form was constructed that balanced both psychometric factors (e.g., item information values) and clinical input. Initial analysis of the simulated CAT and static short form supported both the reliability (i.e., internal consistency and test-retest reliability) and validity (i.e., convergent, discriminant, and known groups) of both administration formats. CONCLUSIONS: The new medication adherence item bank provides a reliable and valid assessment of the ability to take medications accurately among people with T2DM; it will be available in early 2023 through healthmeasures.net.

PURPOSE: The purpose of this study was to develop a new measure, the Re-Engineered Discharge for Diabetes Computer Adaptive Test (REDD-CAT) Illness Burden item bank, to evaluate the impact that a chronic condition has on independent living, the ability to work (including working at home), social activities, and relationships. METHODS: Semi-structured interviews were used to inform the development of an item pool (47 items) that captured patients' beliefs about how a diagnosis of type 2 diabetes interferes with different aspects of their lives. The Illness Burden item bank was developed and tested in 225 people with type 2 diabetes mellitus. RESULTS: No items had sparse response option cells or problems with monotonicity; two items were deleted due to low item-rest correlations. Factor analyses supported the retention of 29 items. With those 29 remaining items, a constrained (common slope) graded response model fit assessment indicated that two items had misfit; they were excluded. No items displayed differential item functioning by age, sex, education, or socio-economic status. The final item bank is comprised of 27 items. Preliminary data supported the reliability (internal consistency and test-retest reliability) and validity (convergent, discriminant, and known-groups) of the new bank. CONCLUSION: The Illness Burden item bank can be administered as a computer adaptive test or a 6-item short form. This new measure captures patients' perceptions of the impact that having type 2 diabetes has on their daily lives; it can be used in conjunction with the REDD-CAT measurement system to evaluate important social determinants of health in persons with type 2 diabetes mellitus.

PURPOSE: The purpose of this study was to develop a new measure to evaluate the ability to receive medical services when needed among persons with type 2 diabetes mellitus. METHODS: The Healthcare Access measure was developed using data from 225 persons with type 2 diabetes mellitus who completed an item pool comprised of 54 questions pertaining to their experience accessing healthcare services. RESULTS: Exploratory and confirmatory factor analyses supported the retention of 45 items. In addition, a constrained graded response model (GRM), as well as analyses that examined item misfit and differential item functioning (investigated for age, sex, education, race, and socioeconomic status), supported the retention of 44 items in the final item bank. Expert review and GRM item calibration products were used to inform the selection of a 6-item static short form and to program the Healthcare Access computer adaptive test (CAT). Preliminary data supported the reliability (i.e., internal consistency and test-retest reliability) and validity (i.e., convergent, discriminant, and known-groups) of the new measure. CONCLUSIONS: The new Healthcare Access item bank can be used to examine the experiences that persons with type 2 diabetes mellitus have with healthcare access, to better target treatment improvements and mitigate disparities; it will be available as a part of the Neuro-Qol measurement system through healthmeasures.net and the PROMIS Application Programmable Interface (API) in early 2023.

OBJECTIVE: To report on the development and calibration of the new Blood Pressure Dysregulation Measurement System (BPD-MS) item banks that assess the effect of BPD on health-related quality of life (HRQOL) and the daily activities of Veterans and non-Veterans with spinal cord injury (SCI). DESIGN: Cross-sectional survey study. SETTING: Two Veteran Affairs medical centers and a SCI model system site. PARTICIPANTS: 454 respondents with SCI (n=262 American Veterans and n=192 non-Veterans; N=454). INTERVENTIONS: Not applicable MAIN OUTCOME MEASURES: The BPD-MS item banks. RESULTS: BPD item pools were developed and refined using literature reviews, qualitative data from focus groups, and cognitive debriefing of persons with SCI and professional caregivers. The item banks then underwent expert review, reading level assessment, and translatability review prior to field testing. The items pools consisted of 180 unique questions (items). Exploratory and confirmatory factor analyses, item response theory modeling, and differential item function investigations resulted in item banks that included a total of 150 items: 75 describing the effect of autonomic dysreflexia on HRQOL, 55 describing the effect of low blood pressure (LBP) on HRQOL, and 20 describing the effect of LBP on daily activities. In addition, 10-item short forms were constructed based on item response theory-derived item information values and the clinical relevance of item content. CONCLUSIONS: The new BPD-MS item banks and corresponding 10-item short forms were developed using established rigorous measurement development standards, which represents the first BPD-specific patient-reported outcomes measurement system unique for use in the SCI population.

OBJECTIVE: 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). DESIGN: Cross-sectional survey study. SETTING: Three academic medical centers and a Veterans Affairs treatment facility. PARTICIPANTS: 376 caregivers of civilians (n=213) and service members/veterans (n=163) with TBI (N=376). INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: 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). RESULTS: 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. CONCLUSIONS: 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.

OBJECTIVE: To compare barriers and facilitators to accessing health care services among service members and veterans (SMVs) by traumatic brain injury (TBI) severity groups. DESIGN: Qualitative descriptive study guided by an access to health care services conceptual framework. SETTING: Five Veterans Affairs (VA) polytrauma rehabilitation centers. PARTICIPANTS: SMVs (N=55, including 10 caregivers as proxies) ≥2 years post-TBI recruited from the VA TBI Model Systems and grouped by TBI severity (mild/moderate, severe). MAIN OUTCOME MEASURES: Barriers and facilitators accessing care. RESULTS: The main facilitators included ease of communicating with providers to help SMVs identify and utilize appropriate health care, family advocates who promoted engagement in health care, ability to use government and community facilities, and online resources or equipment. Distance to services was uniformly identified as a main barrier for both patient groups. However, facilitators and barriers to health care access differed by TBI severity. SMVs with severe TBI highlighted the role of nonprofit organizations in promoting health care engagement and the availability of VA specialty residential programs in meeting health care needs. Having unrecognized health care needs in chronic stages and communication difficulties with providers were more commonplace for those with greater TBI severity and affected quality of care. Those with mild/moderate TBI highlighted challenges associated with paying for services in the community and scheduling of services. CONCLUSIONS: Barriers and facilitators exist across multiple dimensions of a health care access framework and vary by TBI severity. Results suggest possible mechanistic links between health care access and SMV health outcomes. Findings support current policy and practice efforts to facilitate health care access for SMVs with TBI but highlight the need for tailored approaches for those with greater disability.

OBJECTIVE: This study aimed to examine same-day associations of pain, fatigue, depressed mood, anxiety, and perceived cognitive function with social participation in the daily lives of adults with spinal cord injury (SCI). DESIGN: Observational study used a combination of baseline surveys and 7 end-of-day (EOD) diaries. SETTING: General community. PARTICIPANTS: Individuals with SCI (N=168; mean age, 49.8y; 63% male, 37% female). MAIN OUTCOME MEASURES: Patient-Reported Outcomes Measurement Information System short form measures (Ability to Participate in Social Roles and Activities, Pain Intensity, Depression, Anxiety, Cognitive Function Abilities) were adapted for daily administrations as EOD diaries. RESULT: Results of multivariable model showed that daily increases in fatigue (B=-0.10; P=.004) and depressive symptoms (B=-0.25; P=<.001) and decreases in perceived cognitive function (B=0.11; P=<.001) were significantly related to worse same-day social participation. Daily fluctuations in anxiety and pain were unrelated to same-day social participation. CONCLUSIONS: This is the first study that shows within-person associations of common SCI symptoms with social participation in the daily lives of adults with SCI. Results from the current study may help to develop more effective individualized treatments of symptoms and symptom effect aimed at improving social participation.

OBJECTIVE: Although sleep difficulties are common after spinal cord injury (SCI), little is known about how day-to-day fluctuations in sleep quality affects health-related quality of life (HRQOL) among these individuals. We examined the effect of sleep quality on same-day HRQOL using ecological momentary assessment methods over a 7-day period. DESIGN: Repeated-measures study involving 7 days of home monitoring; participants completed HRQOL measures each night and ecological momentary assessment ratings 3 times throughout the day; multilevel models were used to analyze data. SETTING: Two academic medical centers. PARTICIPANTS: A total of 170 individuals with SCI (N=170). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Daily sleep quality was rated on a scale of 0 (worst) to 10 (best) each morning. Participants completed end-of-day diaries each night that included several HRQOL measures (Sleep Disturbance, Sleep-related Impairment, Fatigue, Cognitive Abilities, Pain Intensity, Pain Interference, Ability to Participate in Social Roles and Activities, Depression, Anxiety) and ecological momentary assessment ratings of HRQOL (pain, fatigue, subjective thinking) 3 times throughout each day. RESULTS: Multilevel models indicated that fluctuations in sleep quality (as determined by end-of-day ratings) were significantly related to next-day ratings of HRQOL; sleep quality was related to other reports of sleep (Sleep Disturbance; Sleep-related Impairment; Fatigue) but not to other aspects of HRQOL. For ecological momentary assessment ratings, nights of poor sleep were related to worse pain, fatigue, and thinking. Generally, sleep quality showed consistent associations with fatigue and thinking across the day, but the association between sleep quality and these ecological momentary assessment ratings weakened over the course of the day. CONCLUSIONS: Findings highlight the important association between sleep and HRQOL for people with SCI. Future work targeting sleep quality improvement may have positive downstream effects for improving HRQOL in people with SCI.

PURPOSE: As Huntington disease (HD) progresses, speech and swallowing difficulties become more profound. These difficulties have an adverse effect on health-related quality of life (HRQOL), thus psychometrically robust measures of speech and swallowing are needed to better understand the impact of these domains across the course of the disease. Therefore, the purpose of this study is to establish the clinical utility of two new patient-reported outcome measures (PROs), HDQLIFE Speech Difficulties and HDQLIFE Swallowing Difficulties. METHODS: Thirty-one participants with premanifest or manifest HD, and 31 age- and sex-matched healthy control participants were recruited for this study. Participants completed several PROs [HDQLIFE Speech Difficulties, HDQLIFE Swallowing Difficulties, Communication Participation Item Bank (CPIB)], as well as several clinician-rated assessments of speech and functioning. A computational algorithm designed to detect features of spoken discourse was also examined. Analyses were focused on establishing the reliability and validity of these new measures. RESULTS: Internal consistency was good for Swallowing (Cronbach's alpha = 0.89) and excellent for Speech and the CPIB (both Cronbach's alpha ≥ 0.94), and convergent/discriminant validity was supported. Known groups validity for the PROs was supported by significant group differences among control participants and persons with different stages of HD (all p < 0.0001). All PROs were able to distinguish those with and without clinician-rated dysarthria (likelihood ratios far exceeded the threshold for clinical decision making [all ≥ 3.28]). CONCLUSIONS: Findings support the clinical utility of the HDQLIFE Speech and Swallowing PROs and the CPIB for use across the HD disease spectrum. These PROs also have the potential to be clinically useful in other populations.

BACKGROUND: Dietary sodium excess and malnutrition have been associated with poor outcomes in heart failure (HF). Few previous studies have examined the barriers to following a low-sodium, nutritionally robust diet in hospitalized patients with HF. METHODS AND RESULTS: As part of a dietary intervention pilot study, 76 inpatients with HF (age 71⯱â¯8 years, 30% female, 30% black, 36% Hispanic/Latino) completed 2 questionnaires, the Dietary Sodium Restriction Questionnaire (DSRQ) and the Brief Dietary Psychosocial Scale (BDPS), to assess challenges in following a low-sodium, nutritionally complete diet. We assessed the factor structure of the DSRQ and BDPS with confirmatory and exploratory factor analysis (CFA and EFA). CFA did not support the established 3-factor solution for the DSRQ; instead, EFA indicated that a 2-factor solution (subjective norms/attitudes and perceived behavioral control) provided the best fit for the data. EFA supported 4 separate factors for the BDPS, as in its original derivation. Cronbach's alphas supported internal consistency reliability for both scales (DSRQ: 0.85-0.94; BDPS: 0.72-0.95). CONCLUSIONS: In a mixed-ethnicity group of hospitalized older patients with HF, the DSRQ and BDPS have reasonable psychometric properties. These questionnaires may help identify barriers to healthy dietary practices and facilitate nutritional interventions in this high-risk population.

BACKGROUND: Huntington's disease (HD) is a neurological disorder that causes severe motor symptoms that adversely impact health-related quality of life. Patient-reported physical function outcome measures in HD have shown cross-sectional evidence of validity, but responsiveness has not yet been assessed. OBJECTIVES: This study evaluates the responsiveness of the Huntington Disease Health-Related Quality of Life (HDQLIFE) and the Quality of Life in Neurological Disorders (Neuro-QoL) physical function measures in persons with HD. METHODS: A total of 347 participants completed baseline and at least 1 follow-up (12-month and 24-month) measure (HDQLIFE Chorea, HDQLIFE Swallowing Difficulties, HDQLIFE Speech Difficulties, Neuro-QoL Upper Extremity Function, and/or Neuro-QoL Lower Extremity Function). Of the participants that completed the baseline assessment, 338 (90.9%) completed the 12-month assessment, and 293 (78.8%) completed the 24-month assessment. Standardized response means and general linear models evaluated whether the physical function measures were responsive to self-reported and clinician-rated change over time. RESULTS: Small to moderate effect sizes for the standardized response means supported 12-month and 24-month responsiveness of the HDQLIFE and Neuro-QoL measures for those with either self-reported or clinician-rated declines in function. General linear models supported 12-month and 24-month responsiveness for all HRQOL measures relative to self-reported declines in health, but generally only 24-month responsiveness was supported relative to clinician-rated declines in function. CONCLUSIONS: Longitudinal analyses indicate that the HDQLIFE and the Neuro-QoL physical function measures are sensitive to change over time in individuals with HD. Thus, these scales exhibit evidence of responsiveness and may be useful outcome measures in future clinical trials. © 2019 International Parkinson and Movement Disorder Society.

PURPOSE: Individuals with Huntington disease (HD) experience progressive cognitive decline that may appear years before motor manifestations of the disease. These declines have a profound effect on health-related quality of life (HRQOL) over the disease course, and thus it is important that self-report measures of cognitive function are validated for use in longitudinal studies. METHODS: 359 individuals with premanifest or manifest HD completed baseline and at least one follow-up (12- and 24-month) assessment. Neuro-QoL™ Cognitive Function was administered at each time-point. Participants completed a self-reported global rating of cognitive change, as well as performance-based cognitive changes (using the Symbol Digit Modalities Test). Standardized response means (SRMs) and general linear models evaluated whether Neuro-QoL™ Cognitive Function was responsive to change over time with respect to self-reported and performance-based anchors. Test-retest reliability and known-group validity were also examined. RESULTS: Responsiveness was supported by effect sizes that were small in magnitude, but in the expected direction relative to self-reported and performance-based change. General linear models generally supported 12- and 24-month responsiveness relative to self-reported cognitive change and 12-month responsiveness relative to performance-based change. Test-retest reliability was excellent, and the measure exhibited known-group validity. CONCLUSION: Longitudinal analyses generally indicate that the Neuro-QoL™ Cognitive Function measure is sensitive to change over time in individuals with HD. Neuro-QoL Cognitive Function changes reflect self-reported cognitive change at 12 and 24 months and performance-based change at 12 months. This measure may be useful in clinical trials or longitudinal observation studies.

BACKGROUND: The majority of persons with Huntington disease (HD) experience mental health symptoms. Patient-reported outcome (PRO) measures are capable of capturing unobservable behaviors and feelings relating to mental health. The current study aimed to test the reliability and responsiveness to self-reported and clinician-rated change over time of Neuro-QoL and PROMIS mental health PROs over the course of a 24-month period. METHODS: At baseline, 12-months, and 24-months, 362 participants with premanifest or manifest HD completed the Neuro-QoL Depression computer adaptive test (CAT), PROMIS Depression short form (SF), Neuro-QoL Anxiety CAT, PROMIS Anxiety SF, PROMIS Anger CAT and SF, Neuro-QoL Emotional/Behavioral Dyscontrol CAT and SF, Neuro-QoL Positive Affect and Well-Being CAT and SF, and Neuro-QoL Stigma CAT and SF. Participants completed several clinician-administered measures at each time point, as well as several global ratings of change at 12- and 24-months. Reliability (test-retest reliability and measurement error) and responsiveness (using standardized response means and general linear models) were assessed. RESULTS: Test-retest reliability and measurement error were excellent for all PROs (all ICC ≥ .90 for test-retest reliability and all SEM percentages ≤ 6.82%). In addition, 12- and 24-month responsiveness were generally supported for the Neuro-QoL and PROMIS mental health PROs; findings relative to clinician-rated anchors of change (e.g., SRMs for the group with declines ranged from .38 to .91 for 24-month change and .09 to .45, with the majority above .25 for 12-month change) were generally more robust than those relative to self-reported anchors of change (e.g., SRMs for the group with declines ranged from .02 to .75, with the majority above .39 for 24-month change and .09 to .45, with the majority above .16 for 12-month change). CONCLUSIONS: The Neuro-QoL and PROMIS mental health PROs demonstrated strong psychometric reliability, as well as responsiveness to self-reported and clinician-rated change over time in people with HD.

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 (χ2 [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.

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.

OBJECTIVES: To understand the factor structure of health-related quality of life specific to caregivers of people living with traumatic brain injury (TBI). DESIGN: Prospective, cross-sectional data collection. SETTING: Three TBI Model Systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility. PARTICIPANTS: Caregivers (N=558) of people who have sustained a TBI (344 caregivers of civilians and 214 caregivers of service members or veterans; 85% women; 58% spouses; mean age, 46.12±14.07y) who have provided care for an average of 5.82±5.40 years. INTERVENTIONS: Not applicable. MAIN OUTCOMES MEASURES: The Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) measurement system including 10 Patient-Reported Outcomes Measurement Information System item banks (anger, anxiety, depression, social isolation, sleep disturbance, fatigue, ability to participate in social roles and activities, satisfaction with social roles and activities, emotional support, informational support) and 5 TBI-CareQOL banks (feelings of loss-self, feelings of loss-person with TBI, feeling trapped, caregiver-specific anxiety, caregiver strain). RESULTS: Confirmatory factor analysis model fit indices were compared for 14 empirically derived and 5 theoretically derived models. Confirmatory factor analysis results indicated that the best model fit was for a 6-factor model with dimensions that included mental health, social support, social participation, social isolation, physical health, and caregiver emotion. CONCLUSIONS: Results indicated that a 6-factor model provided the best model fit for health-related quality of life in caregivers of individuals with TBI. These results have utility for both research and clinical applications. Establishing the TBI-CareQOL's factor structure provides preliminary evidence of the measurement system's construct validity, helps inform the selection of measures for specific research or clinical interventions, and informs the development of composite scores.

OBJECTIVE: To investigate the relationship of 2 health-related quality-of-life (QOL) item banks (Emotional Suppression and Caregiver Vigilance), developed for caregivers of service members/veterans with traumatic brain injury (TBI), to caregivers' positive and negative affect. SETTING: Community. PARTICIPANTS: One hundred sixty-five caregivers of service members/veterans with TBI. DESIGN: Retrospective database analysis. MAIN MEASURES: TBI-CareQOL Emotional Suppression; TBI-CareQOL Caregiver Vigilance; measures of negative (Patient-Reported Outcomes Measurement Information System [PROMIS] Depression, PROMIS Anger, TBI-CareQOL Caregiver-Specific Anxiety, National Institutes of Health Toolbox [NIHTB] Perceived Stress, GAD-7) and positive affect (Neuro-QOL Positive Affect and Well-being, NIHTB Self-efficacy, NIHTB General Life Satisfaction, Family Resilience Scale for Veterans, TBI-QOL Resilience). RESULTS: When considered separately, linear regression showed that higher levels of Emotional Suppression and greater Caregiver Vigilance were individually associated with more negative affect and less positive affect. When considered together, the pattern of findings was generally consistent for both Emotional Suppression and Caregiver Vigilance with regard to negative affect and for Emotional Suppression with regard to positive affect. However, when considered together, Caregiver Vigilance was no longer related to positive affect. CONCLUSIONS: Caregivers with high emotional suppression and/or vigilance are more likely to show emotional distress and less likely to have positive affect than caregivers with lower levels of emotional suppression and vigilance. A combination of education and individual counseling targeting coping with negative emotions and TBI-related problems may be beneficial.

Chorea, a hallmark symptom of Huntington's disease (HD), is characterized by jerky involuntary movements affecting the whole body that can interfere with daily functioning and impact health-related quality of life (HRQOL). To characterize chorea's impact on everyday functioning and HRQOL and identify patterns of perception and experiences of chorea among patients, caregivers, and providers. Data from focus groups of individuals with manifest HD (n = 8 early-stage HD; n = 16 late-stage HD), individuals at-risk or prodromal HD (n = 16), family HD caregivers (n = 17), and HD clinicians (n = 25). Focus group recordings were transcribed verbatim and analysed via constant comparison to identify meaningful and salient themes of living with chorea. Global themes of chorea's impact identified included: watching for chorea, experiences of stigma, and constraints on independence and relationships. Themes distinct to specific respondent groups included: Vigilance (at risk, prodromal); adaptation to chorea (early-stage); loss of autonomy and social life (late-stage); monitoring engagement (family caregivers) and safety (clinical providers). Living with chorea significantly constrains daily functioning, interactions, and HRQOL across the HD disease spectrum. Addressing these impacts via appropriate management of chorea can potentially enhance functioning, HRQOL, and overall satisfaction for persons with HD and their families.

OBJECTIVE: Preference-sensitive surgical decisions merit shared decision-making, as decision engagement can reduce decisional conflict and regret. Elective cleft-related procedures are often preference sensitive, and therefore, we sought to better understand decision-making in this population. DESIGN: Semistructured interviews were conducted to elicit qualitative data. A hierarchical codebook was developed through an iterative process in preparation for thematic analysis. Thematic analysis was performed to examine differences between patients and caregivers. SETTING: Multidisciplinary cleft clinic at a tertiary care center. PARTICIPANTS: Patients with cleft lip aged 8 and older (n = 31) and their caregivers (n = 31) were purposively sampled. Inability to converse in English, intellectual disability, or syndromic diagnoses resulted in exclusion. MAIN OUTCOME MEASURES: Preferences surrounding surgical decision-making identified during thematic analysis. RESULTS: Mean patient age was 12.7 (standard deviation: 3.1). Most had unilateral cleft lip and palate (43.8%). Three themes emerged: Insufficient Understanding of Facial Difference and Treatment, Diversity of Surgical Indications, and Barriers to Patient Autonomy. Almost half of caregivers believed their children understood their clefts, but most of these children failed to provide information about their cleft. Although many patients and caregivers acknowledged that surgery addressed function and/or appearance, patients and caregivers exhibited differences regarding the necessity of surgery. Furthermore, a large proportion of patients believed their opinions mattered in decisions, but less than half of caregivers agreed. CONCLUSIONS: Patients with clefts desire to participate in surgical decisions but have limited understanding of their facial difference and surgical indications. Cleft surgeons must educate patients and facilitate shared decision-making.
