Development and validation of the positive affect and well-being scale for the neurology quality of life (Neuro-QOL) measurement system

Validation of the Patient-Reported Outcomes Measurement Information System Pain Intensity and Brief Pain Inventory During Pregnancy

OBJECTIVES

We sought to (1) validate the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Short Form 3a measure and Brief Pain Inventory (BPI) for assessing pain during pregnancy and (2) evaluate pain in a sample of pregnant individuals.

METHODS

Pregnant individuals (N = 196) were prospectively surveyed: n = 171 up to 22 weeks gestational age, n = 123 during their third trimester of pregnancy, and n = 98 both times. Additional measures included SPRINT Post-Traumatic Stress Disorder Tool, Neurological Quality of Life, Edinburgh Postnatal Depression Scale and anxiety subscale, and Adverse Childhood Experiences Questionnaire. Validity evidence examined included content validity, reliability, convergent and discriminant validity, and relevant criterion relationships.

RESULTS

Content validity analysis suggests that the PROMIS pain measure was easy to use and interpret while the BPI provided more detail. However, BPI questions regarding medication usage and relief were unclear to some pregnant individuals. In addition, the relationships among pain ratings were stronger than relationships between pain ratings and measures intended to assess other constructs suggesting convergent and discriminant validity. Relationships with relevant criterions were presented for both the PROMIS and BPI by comparing ratings of pain intensity and severity for pregnant individuals with and without areas of pain reported on BPI.

CONCLUSION

Results indicate that PROMIS and BPI provided valid information on pain intensity or severity for our perinatal sample. Depending on the research question, the PROMIS pain or BPI may be more appropriate to an individual study. Either measure could also be included in an electronic health record for accurate pain assessment in clinical settings.

Neurologic Quality of Life Outcomes in Patients with Normal Pressure Hydrocephalus After Ventriculoperitoneal Shunt Placement: A Prospective Assessment of Cognition, Mobility, and Social Participation

BACKGROUND

Idiopathic normal pressure hydrocephalus (iNPH) typically presents with gait disturbances, cognitive decline, and urinary incontinence. Symptomatic improvement generally occurs following shunt placement, but limited evidence exists on the quality of life (QOL) metrics in iNPH. Therefore, we conducted a prospective study of the effect of shunt placement on QOL in iNPH patients, using Quality of Life in Neurologic Disorders (Neuro-QOL) metrics.

METHODS

Eligible patients underwent shunt placement after evidence of symptomatic improvement following temporary cerebrospinal fluid diversion via inpatient lumbar drain trial. Patients were administered short- and long-form Neuro-QOL assessments prior to shunt placement and at 6-month and 1-year postoperative timepoints to evaluate lower extremity mobility, cognitive function, and social roles and activities participation. Changes in QOL measures were analyzed using a repeated-measures linear mixed effects model.

RESULTS

There were 48 patients with a mean age of 75.4 ± 6.3 years. Average short-form mobility scores improved by 3.9 points (14.6%) at 6-month follow-up and by 6.2 points (23.2%) at 1-year follow-up compared with preoperative baseline (P = 0.027 and P = 0.0002, respectively). Short-form cognition scores increased by 5.2 points (22.4%) at 6 months and 10.9 points (47.0%) at 1 year postoperatively (P = 0.007 and P < 0.0001, respectively). On long-form assessment, social roles and activity participation scores improved by 29.3 points (23.4%) at 6 months and 31.6 points (25.2%) at 1 year after surgery compared to baseline (P = 0.028 and P = 0.02, respectively).

CONCLUSIONS

Our findings demonstrate that shunt placement leads to improved QOL in iNPH patients across multiple domains. Significant improvements in mobility, cognition, and social roles and activity participation are realized within the first 6 months and are sustained on 1-year follow-up.

A hybrid type II effectiveness-implementation trial of a positive emotion regulation intervention among people living with HIV engaged in Ryan White Medical Case Management: protocol and design for the ORCHID study

BACKGROUND

The Ryan White Medical Case Management System, which serves more than half of people living with HIV (PLWH) in the USA, is an opportune setting for identifying and addressing depression among PLWH. A growing body of research suggests that interventions that promote positive emotion may lessen symptoms of depression and improve physical and psychological well-being among people experiencing a variety of health-related stress, including living with HIV. Research on how best to integrate standardized mental health screening and referral to evidence-based interventions in Ryan White Medical Case Management settings has the potential to improve the health and wellbeing of PLWH.

METHODS

This mixed-methods study will enroll up to N = 300 Ryan White clients who screen positive for depressive symptoms in ORCHID (Optimizing Resilience and Coping with HIV through Internet Delivery), a web-based, self-guided positive emotion regulation intervention. The study will be conducted in 16 Ryan White Medical Case Management clinics in Chicago, IL. Following pre-implementation surveys and interviews with Medical Case Managers (MCMs) and Supervisors to develop an implementation facilitation strategy, we will conduct a hybrid type 2 implementation-effectiveness stepped wedge cluster randomized trial to iteratively improve the screening and referral process via interviews with MCMs in each wedge. We will test the effectiveness of ORCHID on depression and HIV care outcomes for PLWH enrolled in the program. RE-AIM is the implementation outcomes framework and the Consolidated Framework for Implementation Research is the implementation determinants framework.

DISCUSSION

Study findings have the potential to improve mental health and substance use screening of Ryan White clients, decrease depression and improve HIV care outcomes, and inform the implementation of other evidence-based interventions in the Ryan White Medical Case Management System.

Bidirectional temporal associations between sleep and affect and cognitive symptoms among community-dwelling stroke survivors: An ecological momentary assessment study

INTRODUCTION

Sleep plays a critical role in daily functioning and stroke recovery but receives little attention in stroke rehabilitation. Sleep disturbances are linked to affective and cognitive impairments, but temporal associations between sleep and affect and cognitive symptoms are less clear. Understanding these temporal associations may inform new directions in intervention and prevention to support continued stroke recovery.

OBJECTIVE

To examine the bidirectional temporal associations between sleep and affect and cognitive symptoms among community-dwelling stroke survivors.

DESIGN

A secondary analysis of a longitudinal observational study involving 7 days of ecological momentary assessment (EMA), during which participants completed eight EMA surveys and a sleep diary per day. Multilevel modeling was used to analyze data.

SETTING

Community.

PARTICIPANTS

Community-dwelling stroke survivors (N = 40).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

EMA measures of depressed affect, cheerful affect, and cognitive symptoms. Sleep quality and duration as measured using a sleep diary.

RESULTS

Between-person sleep quality was negatively associated with next-day depressed affect (B = -.16; p = .028) and positively associated with next-day cheerful affect (B = .63; p < .001). Inversely, between-person depressed affect was negatively associated with next night sleep quality (B = -.77; p = .015), and vice versa for cheerful affect (between-person: B = .45; p < .001; within-person: B = .09; p = .008). Long sleep (>9 hours) was positively associated with next-day cognitive symptoms (B = .13; p = .002), whereas cognitive symptoms were associated with a higher odds of long sleep the following night (odds ratio [OR] = 0.25; p = .047).

CONCLUSIONS

This study identified the bidirectional associations of sleep with affect and cognitive symptoms in the context of the everyday life of stroke survivors. The findings suggest that interventions addressing sleep quality and duration may impact affect and cognitive symptoms, and vice versa.

Development and validation of the HDSIM™ assessment system: a measure of hemorrhoid disease symptom impact

BACKGROUND

Hemorrhoid disease (HD) affects 10 million people in the US at any given time, and 50% of the US population will develop symptomatic hemorrhoids during their lifetime. Approximately 60% of people with hemorrhoids experience symptoms. Despite its prevalence and impact on quality of life, the existing patient-reported outcome measures of HD have not been validated using standard psychometric methods. The present study thus aimed to develop the Hemorrhoid Disease Symptom Impact Measure™ (HDSIM™) assessment system, a patient-reported measure of HD symptoms and impact for use in HD clinical research.

METHODS

On the basis of results from qualitative cognitive interviews, we generated the conceptual model and item pool. A cross-sectional web-based survey (n = 1066) was done, including a randomly selected retest subsample (n = 100) 1-2 weeks later. The survey sample was selected to be evenly distributed across mild, moderate, and severe levels of disease and to be nationally representative of the general United States population in terms of race, gender, and region. Existing disease-specific measures of symptoms and generic measures of quality of life and well-being were compared to the new tool for construct validation.

RESULTS

The HDSIM system includes 38 items representing six conceptual-model-driven subscales, aligning with the conceptual model: Symptoms at Worst, Symptoms at Best, Bowel Health Impact, Life Impact, Mental Health Impact, and Manageability. Psychometric analyses documented that the subscales had excellent internal consistency reliability, cross-sectional construct validity (i.e., convergent and divergent validity, known groups validity), test-retest stability, and longitudinal construct validity (i.e., responsiveness).

CONCLUSION

The HDSIM system is fit for purpose in hemorrhoid disease clinical trials research. Since measures are validated in an iterative manner over many studies and over time, the present study results should be considered preliminary.

Associations of Circadian Rest-Activity Rhythms With Affect and Cognition in Community-Dwelling Stroke Survivors: An Ambulatory Assessment Study

BACKGROUND

Rest-activity rhythm (RAR) is a modifiable behavioral factor associated with affect and cognition. Identifying RAR characteristics associated with affect and cognition among stroke survivors provides insight into preventing poststroke affective and cognitive impairment.

OBJECTIVE

To examine the associations of RAR characteristics with affect and cognition among community-dwelling stroke survivors.

METHODS

Forty participants with mild stroke (mean age = 52.8; 42.5% female; 55% White) reported their affect and cognitive complaints using ecological momentary assessment and wore an accelerometer for 7 consecutive days and completed the National Institutes of Health Toolbox Cognition Battery. RAR characteristics were extracted using parametric and non-parametric approaches. Multivariable linear regressions were used to identify RAR characteristics associated with affect and cognition.

RESULTS

Later onset of rest (B = 0.45; P = .008) and activity (B = 0.36; P = .041) were positively associated with depressed affect. These associations were reversed for cheerful effect (rest onset: B = -0.42; P = .017; activity onset: B = -0.39; P = .033). Cheerful affect was also positively associated with relative amplitude (ie, distinctions in activity levels between rest and activity; B = .39; P = .030). Intra-daily variability (ie, RAR fragmentation; B = 0.35; P = .042) and later onset of activity (B = .36; P = .048) were positively associated with cognitive complaints. Less erratic RAR was positively associated with fluid cognition (B = 0.29; P = .036); RAR fragmentation was positively associated with crystallized cognition (B = 0.39; P = .015).

CONCLUSIONS

We identified RAR correlates of affect and cognition among stroke survivors, highlighting the value of managing RAR and sleep in stroke rehabilitation. Future studies should test whether advancing the onset of rest and activity, promoting a regular active lifestyle, and improving rest and sleep in the nighttime protect stroke survivors from affective and cognitive impairment.

A Remotely Delivered, Personalized Music Therapy Pilot Intervention for Lonely Older Adults During the Covid-19 Pandemic

Introduction

This study investigated a remotely delivered, therapist-facilitated, personalized music listening intervention for community-dwelling older adults experiencing loneliness during the Covid-19 pandemic. We assessed its feasibility and individuals' experiences of social connection and emotional well-being during the intervention.

Methods

Ten cognitively unimpaired older adults who endorsed loneliness completed eight weekly sessions with a board-certified music therapist via Zoom. Participants were guided in developing two online personalized music playlists and were asked to listen to playlists for at least one hour daily. Feasibility metrics were attendance, accessibility, and compliance rates. Post-study interview responses were analyzed using a rapid qualitative methodology. Exploratory pre- and post-study measures of loneliness and other aspects of psychological well-being were obtained using validated questionnaires.

Results

Ten participants (mean age 75.38 [65 to 85] years, 80% women) were enrolled from March to August 2021. Attendance and compliance rates were 100% and the accessibility rate was 90%. Most participants associated music with positive memories before the program and many reported that the intervention prompted them to reconnect with music or listen to music with greater intention. They cited increased connection from interacting with the music therapist and the music itself, as well as specific positive emotional impacts from integrating music into their daily lives. Median pre- to post-questionnaire measures of psychological function all changed in an improved direction.

Discussion

Remotely delivered music therapy may be a promising intervention to promote regular music listening and socioemotional well-being in lonely older adults.

Development and Implementation of a Culturally Informed Spanish Language Yoga Program for Latiné Women With Overweight or Obesity Diagnosed With Cancer: A Single Arm Pilot Study

Background

Given limited yoga research in health disparities populations, we developed and evaluated a 12-week Spanish language yoga program for Latiné women with overweight or obesity affected by cancer. The program aimed to empower participants through culturally tailored yoga practice and opportunities for social connection and support.

Methods

Partnering with a community-based organization, the program was co-created by bilingual (English and Spanish-speaking) yoga instructors, Latiné cancer survivor support professionals, and integrative medicine researchers. The single arm intervention consisted of 12 separate, 60-minute Hatha yoga classes, including physical postures, breathing exercises, culturally relevant poetry, and post-practice socialization opportunities. Measures were administered at baseline, 12-week, and 24-week.

Results

Thirty-five eligible participants enrolled in the program, demonstrating high feasibility and relevance as well as high levels of engagement in home practice. Some participants faced barriers to regular home practice, including family responsibilities and concerns about proper pose execution. Preliminary outcome analyses indicated improvements in sleep disturbance, pain interference, depression, and blood pressure post-intervention, with sustained improvements in depression, anxiety, and blood pressure at 24-week. No significant changes were observed in fatigue, physical function, positive affect, satisfaction with social roles and activities, and weight. Structured post-practice social snack time with yoga instructors (compared with unstructured time with peers) was associated with self-reported improvements in satisfaction with social roles and activities and weight loss.

Conclusion

This yoga program successfully engaged female Latiné cancer survivors with overweight and obesity and serves as a foundational step in empowering this population to improve their health and well-being through culturally tailored yoga practice. Future research should utilize controlled study designs and engage participants from different geographical regions to study the efficacy and sustainability of findings.

QALYs and rare diseases: exploring the responsiveness of SF-6D, EQ-5D-5L and AQoL-8D following genomic testing for childhood and adult-onset rare genetic conditions in Australia

BACKGROUND

Genomic testing transforms the diagnosis and management of rare conditions. However, uncertainty exists on how to best measure genomic outcomes for informing healthcare priorities. Using the HTA-preferred method should be the starting point to improve the evidence-base. This study explores the responsiveness of SF-6D, EQ-5D-5L and AQoL-8D following genomic testing across childhood and adult-onset genetic conditions.

METHOD

Self-reported patient-reported outcomes (PRO) were obtained from: primary caregivers of children with suspected neurodevelopmental disorders (NDs) or genetic kidney diseases (GKDs) (carers' own PRO), adults with suspected GKDs using SF-12v2; adults with suspected complex neurological disorders (CNDs) using EQ-5D-5L; and adults with dilated cardiomyopathy (DCM) using AQol-8D. Responsiveness was assessed using the standardised response mean effect-size based on diagnostic (having a confirmed genomic diagnosis), personal (usefulness of genomic information to individuals or families), and clinical (clinical usefulness of genomic information) utility anchors.

RESULTS

In total, 254 people completed PRO measures before genomic testing and after receiving results. For diagnostic utility, a nearly moderate positive effect size was identified by the AQoL-8D in adult DCM patients. Declines in physical health domains masked any improvements in mental or psychosocial domains in parents of children affected by NDs and adult CNDs and DCM patients with confirmed diagnosis. However, the magnitude of the changes was small and we did not find statistically significant evidence of these changes. No other responsiveness evidence related to diagnostic, clinical, and personal utility of genomic testing was identified.

CONCLUSION

Generic PRO measures may lack responsiveness to the diagnostic, clinical and personal outcomes of genomics, but further research is needed to establish their measurement properties and relevant evaluative space in the context of rare conditions. Expected declines in the physical health of people experiencing rare conditions may further challenge the conventional application of quality of life assessments.

The Victim-Offender Overlap in Technology-Facilitated Abuse: Nationally Representative Findings Among U.S. Young Adults

There has been limited examination of the phenomenon of the victim-offender overlap in the field of technology-facilitated abuse (TFA). To design effective strategies to prevent TFA, it is important to understand which individuals are most at risk of victimization, perpetration, and to what extent a subset of people both experience victimization and engage in perpetration. This study drew on Cyber-Abuse Research Initiative (CARI) data, a nationally representative U.S. sample of adults ages 18-35. TFA measurement consisted of parallel scales for victimization and perpetration, each with 27 items assessing forms of technology-facilitated surveillance, monitoring/tracking, interference/communications, reputational harm, controlling/limiting access, and fraud. A bivariate probit of TFA perpetration and TFA victimization, as separate outcomes, was fit to allow for joint estimation of regression coefficients and robust standard errors. Analyses confirmed that TFA, similar to other forms of interpersonal aggression, is characterized by a substantial victim-offender overlap, with 30 percent of the sample reporting involvement both as a victim and as a perpetrator. Internet/social media use and social isolation did not distinguish victimization and perpetration. However, positive and negative affect as well as Lesbian, Gay, Bisexual, Queer, Asexual, or other sexual orientation (LGBQA+) were positively correlated with victimization, whereas female gender and having postsecondary education were positively associated with perpetration. These results may be used to design interventions and anticipate service needs. TFA, as a new topic of research, should capitalize on the theoretical and empirical article related to other forms of the victim-offender overlap.

Moderating Effect of Work on Burden and Hospice Family Caregiver Well-Being

Background: Hospice family caregiving is often physically and emotionally taxing, but it is unclear how employment status impacts hospice caregiver burden and well-being. Objective(s): To examine the relationship between caregiver burden and well-being, and the moderating role of employment status (i.e., working, not working). Design, Setting/Subjects: This was a secondary data analysis of baseline data from a longitudinal observational study of family caregivers of home hospice cancer patients in the United States. Descriptive statistics, correlations, hierarchical linear regressions, and moderation analyses were used. Measurements: Baseline data included demographics, preparedness for caregiving, perceived burden, and well-being (i.e., global health, positive affect and well-being, anxiety, depression). Results: The majority of the 90 participants were White (86.7%), married (71.1%), and college educated (85.6%). The mean age was 58.27 ± 14.22, 53.3% cared for a spouse, and 56.6% worked full or part time. After controlling for demographics, and using employment status as a moderator, greater caregiver burden was significantly associated with lower global health (β = -0.82 [-1.22 to -0.42], p < 0.001), positive affect and well-being scores (β = -0.69 [-1.03 to -0.36], p < 0.001), and higher depression (β = 0.24 [0.12-0.37], p < 0.001) and anxiety scores (β = 0.22 [0.07-0.37], p < 0.005). Employment status significantly moderated the relationship between burden and global health (β = 0.65 [0.22 to 1.08], p < 0.005), and burden and positive affect and well-being (β = 0.45 [0.06 to 0.84], p < 0.05). At high levels of burden, workers had greater well-being than nonworkers. Conclusion(s): More burdened hospice caregivers may experience worse well-being, especially among nonworking caregivers. Employment may be a protective factor for highly burdened hospice family caregivers.

Death Anxiety in Huntington Disease: Longitudinal Heath-Related Quality-of-Life Outcomes

Objective: Death anxiety, represented by the HDQLIFE™ Concern with Death and Dying (CwDD) patient-reported outcome (PRO) questionnaire, captures a person's worry about the death and dying process. Previous work suggests that death anxiety remains an unremitting burden throughout all stages of Huntington disease (HD). Although palliative interventions have lessened death anxiety among people with advanced cancer, none has yet to undergo testing in the HD population. An account of how death anxiety is associated with longitudinal changes to aspects of health-related quality of life (HRQoL) would help optimize neuropalliative interventions for people with HD. Methods: HDQLIFE collected PROs concerning physical, mental, social, and cognitive HRQoL domains and clinician-rated assessments from people with HD at baseline and 12 and 24 months. Linear mixed-effects models were created to determine how baseline death anxiety was associated with follow-up changes in HRQoL PROs after controlling for baseline death anxiety and other disease and sociodemographic covariates. Results: Higher baseline HDQLIFE CwDD is associated with 12- and 24-month declines in HDQLIFE Speech Difficulties, neurology quality of life (NeuroQoL) Depression, Suicidality, HDQLIFE Meaning and Purpose, and NeuroQoL Positive Affect and Well-being. Interpretation: Death anxiety may be a risk factor for worsening mental health and speech difficulty. A further prospective study is required to evaluate whether interventions on death anxiety or mental health generally can reduce declines in HRQoL for people with HD over time.

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

PURPOSE

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

METHODS

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

RESULTS

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

CONCLUSION

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

Feasibility of PROMIS using computerized adaptive testing during inpatient rehabilitation

BACKGROUND

There has been an increased significance on patient-reported outcomes in clinical settings. We aimed to evaluate the feasibility of administering patient-reported outcome measures by computerized adaptive testing (CAT) using a tablet computer with rehabilitation inpatients, assess workload demands on staff, and estimate the extent to which rehabilitation inpatients have elevated T-scores on six Patient Reported Outcomes Measurement Information System® (PROMIS®) measures.

METHODS

Patients (N = 108) with stroke, spinal cord injury, traumatic brain injury, and other neurological disorders participated in this study. PROMIS computerized adaptive tests (CAT) were administered via a web-based platform. Summary scores were calculated for six measures: Pain Interference, Sleep Disruption, Anxiety, Depression, Illness Impact Positive, and Illness Impact Negative. We calculated the percent of patients with T-scores equivalent to 2 standard deviations or greater above the mean.

RESULTS

During the first phase, we collected data from 19 of 49 patients; of the remainder, 61% were not available or had cognitive or expressive language impairments. In the second phase of the study, 40 of 59 patients participated to complete the assessment. The mean PROMIS T-scores were in the low 50 s, indicating an average symptom level, but 19-31% of patients had elevated T-scores where the patients needed clinical action.

CONCLUSIONS

The study demonstrated that PROMIS assessment using a CAT administration during an inpatient rehabilitation setting is feasible with the presence of a research staff member to complete PROMIS assessment.

Examining Physical and Cognitive Function in Chronic Low Back Pain Through the Use of a Multisystem Resilience Framework

OBJECTIVES

Chronic pain results in significant impairment in older adults, yet some individuals maintain adaptive functioning. Limited research has considered the role of positive resources in promoting resilience among older adults. Likewise, these factors have largely been examined independently. We aimed to identify resilience domains based on biopsychosocial factors and explore whether resilience phenotypes vary across sleep disturbance, fatigue, and cognitive function.

METHODS

Sixty adults (ages ≥60 years) with chronic low back pain completed measures of psychological, health, and social functioning. On the basis of previously published analyses, principal-components analysis was conducted to create composite domains for these measures, followed by cluster analysis to identify phenotypes.

RESULTS

Four profiles emerged: Cluster 1, with high levels of psychosocial and health-related functioning; Cluster 2, with high health-related functioning and low psychosocial functioning; Cluster 3, with high psychosocial functioning and poorer health; and Cluster 4, with low levels of functioning across all domains. Significant differences across cluster membership emerged for sleep disturbance (ηp2 = 0.29), fatigue (ηp2 = 0.29), and cognitive abilities (ηp2 = 0.47). Individuals with the highest levels of resilience demonstrated more optimal outcomes in sleep and fatigue (P values ≤0.001) than did individuals with a less resilient phenotype. Furthermore, the High-Resilience group (Cluster 1) and the High Psychosocial / Low Health group (Cluster 3) had lower cognitive impairment than did the High Health / Low Psychosocial group (Cluster 2) and the Low-Resilience group (Cluster 4) (P values ≤0.009).

CONCLUSIONS

A higher array of protective resources could buffer against the negative sequelae associated with chronic low back pain. These exploratory findings support the multidimensional nature of resilience and suggest that targeting resilience from a multisystem perspective might help to optimize interventions for older adults with chronic pain.

Breast sensorisexual function: a novel patient-reported outcome measure of sexual sensory functions of the breast

BACKGROUND

A validated measure assessing sexual sensory functions of the breast is needed to optimize sexual and other health outcomes after breast procedures.

AIM

To describe the development of a patient-reported outcome measure (PROM) to assess breast sensorisexual function (BSF).

METHODS

We applied the PROMIS standards (Patient Reported Outcomes Measurement Information System) for measure development and evaluation of validity. An initial conceptual model of BSF was developed with patients and experts. A literature review yielded a pool of 117 candidate items that underwent cognitive testing and iteration. Forty-eight items were administered to an ethnically diverse, national panel-based sample of sexually active women with breast cancer (n = 350) or without (n = 300). Psychometric analyses were performed.

OUTCOMES

The main outcome was BSF, a measure that assesses affective (satisfaction, pleasure, importance, pain, discomfort) and functional (touch, pressure, thermoreception, nipple erection) sensorisexual domains.

RESULTS

A bifactor model fit to 6 domains-excluding 2 domains with only 2 items each and 2 pain-related domains-revealed a single general factor representing BSF that may be adequately measured by the average of the items. This factor, with higher values denoting better function and with the standard deviation set to 1, was highest among women without breast cancer (mean, 0.24), intermediate among women with breast cancer but not bilateral mastectomy and reconstruction (-0.01), and lowest among those with bilateral mastectomy and reconstruction (-0.56). Between women with and without breast cancer, the BSF general factor accounted for 40%, 49%, and 100% of the difference in arousal, ability to orgasm, and sexual satisfaction, respectively. Items in each of 8 domains demonstrated unidimensionality (ie, they measured 1 underlying BSF trait) and high Cronbach's alphas for the entire sample (0.77-0.93) and the cancer group (0.71-0.95). Correlations with sexual function, health, and quality of life were positive for the BSF general factor and mostly negative for the pain domains.

CLINICAL IMPLICATIONS

The BSF PROM can be used to assess the impact of breast surgery or other procedures on the sexual sensory functions of the breast in women with and without breast cancer.

STRENGTHS AND LIMITATIONS

The BSF PROM was developed by using evidence-based standards, and it applies to sexually active women with and without breast cancer. Generalizability to sexually inactive women and other women warrants further study.

CONCLUSION

The BSF PROM is a measure of women's breast sensorisexual function with evidence of validity among women affected and unaffected by breast cancer.

Coping as a Moderator of Associations Between Symptoms and Functional and Affective Outcomes in the Daily Lives of Individuals With Multiple Sclerosis

BACKGROUND

Pain and fatigue are highly prevalent in multiple sclerosis (MS) and are associated with adverse physical, social, and psychological outcomes. There is a critical need to identify modifiable factors that can reduce the impact of these symptoms on daily life.

PURPOSE

This study examined the moderating role of dispositional coping in the relationships between daily fluctuations (i.e., deviations from a person's usual level) in pain and fatigue and same-day functional/affective outcomes.

METHODS

Adults with MS (N = 102) completed a self-report measure of dispositional coping (Brief COPE), followed by 7 days of ecological momentary assessment of pain and fatigue and end-of-day diaries assessing same-day pain interference, fatigue impact, social participation, upper extremity and lower extremity functioning, depressive symptoms, and positive affect and well-being (PAWB). Multilevel models tested interactions between daily symptom fluctuations and dispositional coping (avoidant/approach) in predicting same-day outcomes.

RESULTS

Higher approach coping mitigated the same-day association between pain and pain interference, whereas higher avoidant coping augmented this association. Daily PAWB benefits were seen for those who reported high approach coping and low avoidant coping; effects were only observed on days of low pain (for approach coping) and low fatigue (for avoidant coping). Avoidant coping was associated with worse fatigue impact, social participation, lower extremity functioning, and depressive symptoms.

CONCLUSIONS

When faced with pain and fatigue, avoidant coping is associated with increased, and approach coping with decreased, functional/affective difficulties in the daily lives of individuals with MS. Altering coping strategy use may reduce the impact of pain and fatigue.

Advance Care Planning and Health-Related Quality of Life in Huntington Disease: Results from a Multicenter National Study

Objective

With Huntington disease (HD), a fatal neurodegenerative disease where the prevalence of suicidal thoughts and behavior (STB) remains elevated as compared to other neurological disorders, it is unknown whether STB and health-related quality of life (HRQoL) affect plans for the end of life or more broadly, advance care planning (ACP). Conversely, it is unknown whether ACP would provoke future changes to STB and HRQoL. Therefore, we sought to evaluate whether STB and HRQoL patient-reported outcomes (PROs) contribute to ACP and whether ACP relates to changes in STB and HRQoL at 24 months.

Methods

HD-validated clinician- and patient-assessments (i.e., HRQoL PROs) were obtained at baseline enrollment, 12 and 24 months through our multi-center study (HDQLIFE™) throughout the United States among people with premanifest, early-stage, and late-stage manifest HD. We used linear mixed-effects models to determine the relationships between STB and HRQoL at baseline and HDQLIFE End of Life Planning at follow-up. Separate linear mixed-effects models were used to assess the relationship between HDQLIFE End of Life Planning at baseline, and HRQoL and STB at 12 and 24 months. False discovery rate adjustments were used to account for multiple comparisons.

Results

At baseline enrollment, STB and HRQoL were not related to HDQLIFE End of Life Planning at 12 or 24 months. Similarly, at baseline, HDQLIFE End of Life Planning demonstrated no association with STB or HRQoL at 12 or 24 months.

Interpretation

STB and HRQoL PROs do not significantly affect patient engagement with ACP. Most importantly, engaging in ACP does not cause untoward effects on HRQoL or STB for this rare neurodegenerative disease where the lifetime prevalence of STB approaches 30%.

Motivation, Physical Activity, and Affect in Community-Dwelling Stroke Survivors: An Ambulatory Assessment Approach

BACKGROUND

Motivation is a frequently reported but far less studied driver for post-stroke physical activity participation. Motivation and physical activity may be important contributors to the prevention management and alleviation of affective symptoms among stroke survivors.

PURPOSE

To investigate the real-time associations between motivation, physical activity, and affect in the daily lives of community-dwelling stroke survivors using ecological momentary assessment (EMA) and accelerometry.

METHODS

Forty community-dwelling stroke survivors wore an accelerometer on the thigh and completed EMA surveys assessing motivation (autonomous motivation, controlled motivation) and affect (negative affect, positive affect) eight times daily for 7 days. Multivariate regression analysis and multilevel modeling investigated the associations between motivation, physical activity, and affect.

RESULTS

Greater autonomous motivation for physical activity was associated with less sedentary behavior (β = -0.40, p = .049) and more moderate-to-vigorous physical activity (β = 0.45, p = .020) participation in daily life. Greater autonomous motivation was momentarily associated with less depressed affect (β = -0.05, p < .001) and greater positive affect (β = 0.13, p < .001). Moreover, greater controlled motivation was momentarily associated with greater depressed affect (β = 0.06, p < .001). More intense physical activity was momentarily associated with greater positive affect (β = 0.13, p = .016). No moderating effect of motivation on the association between physical activity and affect was found.

CONCLUSIONS

Motivation and physical activity are momentarily associated with affect among stroke survivors. Assessing and fostering autonomous motivation may be beneficial for promoting physical activity and managing positive and depressed affect as stroke survivors return to the community.

Mindfulness-based stress reduction for men on active surveillance for prostate cancer and their spouses: Design and methodology of a randomized controlled trial

BACKGROUND

Although active surveillance (AS) is an increasingly adopted treatment paradigm for management of very low risk prostate cancer, many men and their partners face a variety of AS-related psychosocial stressors. Stressors may include anxiety and fear of progression, which may negatively affect short- and long-term psychosocial adjustment and influence early withdrawal from AS in order to seek definitive therapies such as surgery or radiation. Here we describe the protocol for an NCI-funded trial, which seeks to examine the efficacy of mindfulness training compared with a time/attention-matched health promotion control condition in a geographically generalizable sample of men on AS and their spouses.

METHODS

Using a randomized, controlled, partially double-blinded study design, this study involves the delivery of 8 weeks of standardized mindfulness training (MBSR; mindfulness-based stress reduction) and patient reported outcomes over a 12-month period (proposed enrollment of 80 men on AS and spouses), compared with a health promotion control (proposed enrollment of 80 men on AS and spouses) that has been matched for time and attention. Baseline (T1) measures (e.g., anxiety, fear of progression, quality of life) are administered just prior to randomization to the two study arms, followed by repeated assessments at 2 months (T2), 6 months (T3) and 12 months (T4).

CONCLUSION

This study has the potential to offer men and their partners on AS with important educational and self-regulatory skills to better cope and adjust with known stressors related to being placed on this protocol.

The Joy of birds: the effect of rating for joy or counting garden bird species on wellbeing, anxiety, and nature connection

The feeding of garden birds is a popular and accessible means of connecting with wildlife in urban environments in the United Kingdom. Past research has found that the main motivations for feeding birds are psychological benefits, concern for bird welfare, and connecting to nature. This study explores whether a brief birdwatching activity impacts on wellbeing, anxiety, and nature connection. One hundred and fifty-six participants took part in a birdwatching activity, identifying the species that entered their garden during a thirty-minute period. Participants were randomly allocated to the ‘joy’ group, who rated their feeling of joy on seeing each species, or the ‘count’ group, who counted the number of birds of each species. Measures of wellbeing, state anxiety and nature connection were completed before and after the observation period. Both groups had improved wellbeing, anxiety, and nature connection, though decreases in anxiety were greatest for those in the joy group. These results suggest that activating a sense of joy heightens the psychological benefits of watching garden birds. These benefits and the strengthening of nature connections highlight the reciprocal relationship between humans and birds and the importance of actions towards healthy, sustainable urban ecosystems.

The gastrointestinal and microbiome impact of a resistant starch blend from potato, banana, and apple fibers: A randomized clinical trial using smart caps

The gastrointestinal (GI) impact of fibers including resistant starch (RS) consumption depends on various types and amounts of fibers, the initial microbiome states, and accurate intake measurements. A randomized clinical trial evaluated the GI impact of varying doses of a novel resistant starch blend (RSB) with smart cap monitoring. RSB contained at least 50% RS and was a proprietary mixture of a potato starch, green banana flour, and apple fiber powder (a source of apple pectin, not resistant starch). The study design randomized participants to one of four arms: 10 g/day of potato starch (0 RSB), 10 g/day of RSB, 10 to 20 to 20 g/day of RSB or 10 to 20 to 30 g/day RSB for two-week intervals over 6 weeks. Results confirmed that while resistant starch of approximately 5 g per day improves GI symptoms at 2, 4, and 6 weeks, it did not demonstrate a detectable effect on short chain fatty acids. Increasing doses of the blend (RSB) led to a decrease in the diarrhea score. Using an estimate of total consumption of RSB based on smart cap recordings of container openings and protocol-specified doses of RSB, a reduction in the sleep disturbance score was associated with higher RSB dose. The exploratory microbiome evaluation demonstrated that among the 16S rRNA gene sequences most associated with the consumption of the novel blend RSB, two belong to taxa of notable interest to human health: Faecalibacterium and Akkermansia.

Amplification of Positivity Therapy for Co-occurring Alcohol Use Disorder with Depression and Anxiety Symptoms: Pilot Feasibility Study and Case Series

Positive valence system dysregulation is a relatively unexplored transdiagnostic mechanism and potential treatment target underpinning alcohol use and anxiety and depression symptoms. The current study examined the feasibility and potential benefit of a behavioral intervention focused on amplification of positivity (AMP) with eight adults (five female) diagnosed with alcohol use disorder and clinically significant depression or anxiety (ClinicalTrials.gov: NCT04278365). AMP for alcohol use (AMP-A) was delivered in 11 individual sessions involving positive activity interventions integrated alongside psychoeducation and alcohol use monitoring. Case descriptions are provided to illustrate treatment implementation. Treatment credibility and acceptability, participant endorsement of the therapy, and homework compliance were rated moderate to high. Exploratory, intent-to-treat analyses suggested medium to large effect sizes for post-treatment improvements in alcohol use, depression, anxiety, and positive affect. Results provide initial evidence of feasibility and acceptability of AMP-A and will be useful for informing future randomized clinical trials to examine clinical efficacy.

Active coping strategies and less pre-pandemic alcohol use relate to college student mental health during the COVID-19 pandemic

Objective

To further delineate risk and resilience factors contributing to trajectories of mental health symptoms experienced by college students through the pandemic.

Participants

n = 183 college students (67.2% female).

Methods

Linear mixed models examined time effects on depression and anxiety. Propensity-matched subgroups exhibiting "increased" versus "low and stable" depression symptoms from before to after the pandemic-onset were compared on pre-pandemic demographic and psychological factors and COVID-related experiences and coping strategies.

Results

Students experienced worsening of mental health symptoms throughout the pandemic, particularly during Fall 2020 compared with Fall 2019 (Depression scale d = -0.43 [95% CI: -0.65 to -0.21]). The propensity-matched subgroup exhibiting relative resilience ("low and stable" symptoms) reported less alcohol use prior to the pandemic, greater use of active coping strategies, and less of an impact on their college progress.

Conclusions

Results point to several potential targets of screening and intervention to decrease residual impacts of the pandemic.

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

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

Quality of life and experience with the national multiple sclerosis society strategic plan priorities for people with multiple sclerosis: Findings from a path analysis

BACKGROUND: The National Multiple Sclerosis Society (NMSS) strives to ensure that people affected by multiple sclerosis (MS) can live their best lives. This mission is reflected in the Society’s strategic plan, which establishes the roadmap for the Society’s continued commitment to a world free of MS. OBJECTIVE: The purpose of this article is to add to the understanding of both the scope and complexity of the impact of MS and MS-related supports on quality of life (QOL). METHODS: A national sample of people with MS (n = 748) participated in the study by completing validated surveys assessing their QOL, physical and mental health, MS self-efficacy, resilience, participation in NMSS, perceived stress, emotional support, and social roles and activities. A path model was used to examine how the frequently identified MS QOL predictors, including demographic, MS, psychosocial, and physical functional status variables relate to each other and to QOL. RESULTS: The model exhibited reasonable model fit with hypothesized paths being statistically significant and in the hypothesized direction. CONCLUSION: Findings revealed that the relationships among mental health, demographic factors, overall MS experiences, QOL, NMSS participation, and resonance with the mission of the NMSS are complex, highly nuanced, and yet strongly correlated. More importantly, the study highlights the strong influence of variables that are more readily amenable to change through programmatic and clinical intervention, and active self-management and participation.

Protocol for the Healing After Loss (HeAL) Study: a randomised controlled trial of interpersonal psychotherapy (IPT) for major depression following perinatal loss

INTRODUCTION

This protocol describes a study testing the efficacy of interpersonal psychotherapy (IPT) for major depressive disorder following perinatal loss (early and late fetal death and early neonatal death). Perinatal loss is associated with elevated risk of major depressive disorder and post-traumatic stress disorder (PTSD). Perinatal loss conveys specific treatment needs. The trial will be the first fully powered randomised trial of treatment for any psychiatric disorder following perinatal loss.

METHODS AND ANALYSIS

A sample of 274 women in Flint and Detroit areas in Michigan who experience a major depressive episode following a perinatal loss will be randomised to group IPT for perinatal loss or to group coping with depression. We anticipate that 50% of the sample will have co-occurring PTSD. Assessments occur at baseline, mid-treatment (8 weeks), post-treatment (16 weeks) and follow-up (28 weeks). Clinical outcomes include time to recovery from major depressive episode (primary), depressive symptoms, PTSD symptoms and time to recovery from PTSD. Additional outcomes include social support, social role functioning (including parental functioning for those with living children), well-being, grief (including complicated grief and fault beliefs) and fear of subsequent pregnancies. Social support and grief are hypothesised mediators of IPT effects on time to recovery from major depressive episode.

ETHICS AND DISSEMINATION

The trial was approved by Michigan State University's Biomedical Institutional Review Board. It has a data and safety monitoring board and has been submitted to the community-based organisation partners community ethics review board. Written operating procedures outline methods for protecting confidentiality, monitoring and recording adverse events, and safeguarding participants. We will share study results with research and clinical communities, community organisations through which we recruited, and will offer results to study participants. Deidentified datasets will be available through the National Institute of Mental Health Data Archive and to qualified investigators on request.

Drivers of caregiver impact in Duchenne muscular dystrophy: a cohort study

Background

In our companion paper, we addressed the interplay between caregiver impact, out-of-pocket expenditures, and Duchenne Muscular Dystrophy (DMD) disability. We found that DMD caregiver impact could be characterized by four Latent Profile Analysis impact profiles: lowest, lower middle, upper middle, and highest impact. The impact on caregivers was often but not always worse with greater out-of-pocket expenditures. Further, while the lowest-, lower-middle, and highest-impact profiles reflected low, moderate and high disability-related caregiver burden, respectively, the upper-middle profile group was quite variable in level of disability across domains. To better understand the four caregiver-impact profiles, we examine how a comprehensive set of psychosocial factors differentiate the four profile groups.

Methods

Psychosocial factors assessed included demographic characteristics, quality of life (QOL), stress, cognitive appraisal, reserve-building, and general and COVID-specific resilience. Linear modeling examined relationships between impact profiles and psychosocial factors. We used effect size rather than p-value as the criterion for determining relevance of the broad range of characteristics examined.

Results

Multivariate analyses implicated stress and environmental mastery, appraisal sampling of experience, COVID-specific variables, appraisal standards of comparison, appraisal goals, demographics, appraisal combinatory algorithm, reserve-building, and resilience, in order of prominence (average eta² = 0.29, 0.29, 0.16, 0.15, 0.09, 0.07, 0.07, 0.06, 0.05, and 0.02, respectively). On the whole, comparisons of highest-versus-lowest impact profiles revealed more and larger differences than comparisons of upper-middle versus lower-middle impact profiles. Life stress, goals, and reserve-building activities had a smaller differentiating effect in the middle groups.

Conclusion

A more comprehensive ‘story’ about DMD caregiver impact involves life stress, environmental mastery, COVID-specific variables, and cognitive and behavioral factors. Implications are discussed for coaching interventions to support DMD caregivers.

What contextual factors account for anxiety and depressed mood in hospice family caregivers?

OBJECTIVE

End-of-life caregiving is associated with poorer mental health compared with other caregiving. The objective of this study was to examine the association between contextual characteristics and appraisal factors on family caregivers' mental health and well-being.

METHODS

Family hospice caregivers were recruited across four states using a non-probabilistic sampling approach. This study analyzed contextual (demographic, caregiving, economic) and appraisal factors (Medical Outcomes Study Social Support Survey, Zarit Burden Interview) on caregivers' anxiety and depression (Hospital Anxiety and Depression scale, and positive affect and well-being (Positive Affect and Well-being Scale). Hierarchical linear regression models were generated in SPSS version 24.

RESULTS

Data from 102 family caregivers were analyzed. On average, participants were 58.93 years of age (SD = 14.24), mostly female (72.55%), spouses/partners (51.96%), and non-Hispanic White (78.43%). Most (75.49%) described their financial situation as comfortable or more than adequate. Younger age (B = -0.11, 95% CI = -0.18 to -0.05) and increased caregiving burden (B = 0.18, 95% CI = 0.09 to 0.27) were associated with increased anxiety, while lower perceived financial adequacy (B = -1.19, 95% CI = -2.07 to -0.32), lower social support (B = -0.04, 95% CI = -0.06 to -0.01), and increased caregiving burden (B = 0.15, 95% CI = 0.08-0.22) were associated with worsened depression. Greater social support (B = 0.10, 95% CI = 0.05-0.14) and lower caregiving burden (B = -0.19, 95% CI = -0.32 to -0.07) were associated with greater positive affect and well-being.

CONCLUSIONS

Findings suggest significant impact of contextual factors on mental health and well-being, and support the need for holistic assessment of hospice caregivers' wellbeing and programs and policies providing social services and economic support to caregivers.

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

BACKGROUND

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Psychometric properties of the spinal cord injury-quality of life (SCI-QOL) Resilience item bank in a sample with spinal cord injury and chronic pain

PURPOSE

To describe the psychometric properties (e.g., data distribution characteristics, convergent/discriminant validity, internal consistency reliability, and test administration characteristics) of the spinal cord injury quality of life measurement system (SCI-QOL) Resilience item bank delivered as a computer adaptive test (CAT) in a sample of individuals with chronic pain and spinal cord injury (SCI).

METHODS

Descriptive statistics were calculated to investigate variable data distribution characteristics. Correlation analyses were conducted for convergent and discriminant validity. Item response theory-derived reliability was calculated for the SCI-QOL Resilience CAT.

RESULT

One hundred thirty-three adults with SCI (N = 133; 73.5% male, 26.5% female) were enrolled. Sample mean T score on the SCI-QOL Resilience measure was 48.40, SD = 8.60 (min = 29.4; max = 70.0). The CAT administered between 4 (most common, 41.4% of cases) and 12 (9% of cases) items with the Mean_#items = 5.73, SD = 2.45. The SCI-QOL Resilience CAT scores were normally distributed, with very low ceiling (0%) and floor (3%) effects. The SCI-QOL Resilience CAT had a reliability of 0.89, and the mean length of time for respondents to complete the SCI-QOL Resilience CAT was 44.34 s. SCI-QOL Resilience CAT validity was supported by significant moderate correlations with pain acceptance, depressive symptoms, pain catastrophizing, positive affect and well-being, and pain interference (convergent validity) and small non-significant correlations with age, sex, injury level, pain intensity, mobility level, and years since injury (discriminant validity).

CONCLUSION

The SCI-QOL Resilience CAT demonstrated good convergent and discriminant validity. The CAT administration characteristics were impressive: With few items (low response burden), the scale achieved good reliability.

Meaning and purpose in Huntington's disease: a longitudinal study of its impact on quality of life

Objective

Previous work in Huntington’s disease (HD) has shown that a sense of meaning and purpose (M&P) is positively associated with positive affect and well‐being (PAW); however, it was unknown whether HD‐validated patient‐reported outcomes (PROs) influence this association and how M&P impacts PROs in the future. Our study was designed to examine if HD‐validated PROs moderate the relationship between M&P and PAW and to evaluate if baseline M&P predicts 12‐ and 24‐month changes in HD‐validated PROs.

Methods

This was a longitudinal, multicenter study to develop several PROs (e.g., specific for the physical, emotional, cognitive, and social domains) for people with HD (HDQLIFE). The sample consisted of 322 people with HD (n = 50 prodromal, n = 171 early‐stage manifest, and n = 101 late‐stage manifest HD). A single, multivariate linear mixed‐effects model was performed with PAW as the outcome predicted by main effects for M&P and several moderators (i.e., an HD‐validated PRO) and interactions between M&P and a given PRO. Linear‐mixed models were also used to assess if baseline M&P predicted HD‐validated PROs at 12 and 24 months.

Results

Higher M&P was positively associated with higher PAW regardless of the magnitude of symptom burden, as represented by HD‐validated PROs, and independent of disease stage. In our primary analysis, baseline M&P predicted increased PAW and decreased depression, anxiety, anger, emotional/behavioral disruptions, and cognitive decline at 12 and 24 months across all disease stages.

Interpretation

These findings parallel those seen in the oncology population and have implications for adapting and developing psychotherapeutic and palliative HD interventions.

Managing everyday life: Self-management strategies people use to live well with neurological conditions

OBJECTIVE

This paper uses the Taxonomy of Everyday Self-management Strategies (TEDSS) to provide insight and understanding into the complex and interdependent self-management strategies people with neurological conditions use to manage everyday life.

METHODS

As part of a national Canadian study, structured telephone interviews were conducted monthly for eleven months, with 117 people living with one or more neurological conditions. Answers to five open-ended questions were analyzed using qualitative content analysis. A total of 7236 statements were analyzed.

RESULTS

Findings are presented in two overarching patterns: 1) self-management pervades all aspects of life, and 2) self-management is a chain of decisions and behaviours. Participants emphasized management of daily activities and social relationships as important to maintaining meaning in their lives.

CONCLUSION

Managing everyday life with a neurological condition includes a wide range of diverse strategies that often interact and complement each other. Some people need to intentionally manage every aspect of everyday life.

PRACTICE IMPLICATIONS

For people living with neurological conditions, there is a need for health providers and systems to go beyond standard advice for self-management. Self-management support is best tailored to each individual, their life context and the realities of their illness trajectory.

Latent variables for region of interest activation during the monetary incentive delay task

BACKGROUND

The Monetary Incentive Delay task (MID) has been used extensively to probe anticipatory reward processes. However, individual differences evident during this task may relate to other constructs such as general arousal or valence processing (i.e., anticipation of negative versus positive outcomes). This investigation used a latent variable approach to parse activation patterns during the MID within a transdiagnostic clinical sample.

METHODS

Participants were drawn from the first 500 individuals recruited for the Tulsa-1000 (T1000), a naturalistic longitudinal study of 1000 participants aged 18-55 (n = 476 with MID data). We employed a multiview latent analysis method, group factor analysis, to characterize factors within and across variable sets consisting of: (1) region of interest (ROI)-based blood oxygenation level-dependent (BOLD) contrasts during reward and loss anticipation; and (2) self-report measures of positive and negative valence and related constructs.

RESULTS

Three factors comprised of ROI indicators emerged to accounted for >43% of variance and loaded on variables representing: (1) general arousal or general activation; (2) valence, with dissociable responses to anticipation of win versus loss; and (3) region-specific activation, with dissociable activation in salience versus perceptual brain networks. Two additional factors were comprised of self-report variables, which appeared to represent arousal and valence.

CONCLUSIONS

Results indicate that multiview techniques to identify latent variables offer a novel approach for differentiating brain activation patterns during task engagement. Such approaches may offer insight into neural processing patterns through dimension reduction, be useful for probing individual differences, and aid in the development of optimal explanatory or predictive frameworks.

Online prenatal trial in mindfulness sleep management (OPTIMISM): protocol for a pilot randomized controlled trial

Background

Sleep deficiency affects a majority of pregnant women with significant impact on daily function, mood, and pregnancy and birth outcomes. This ongoing study combines two evidence-based strategies for improving sleep and mood, mindfulness meditation and cognitive-behavioral therapy for insomnia (CBT-I), in a unique online format to address the particular needs of pregnant women. The purpose of this study is to test the feasibility and estimate the efficacy of this novel 6-week online mindfulness meditation intervention to help pregnant women in remission from depression self-manage insomnia.

Methods

This is a two-arm, parallel group randomized controlled trial. A total of 50 pregnant women between 12 and 28 weeks gestation will be recruited from the community and randomly assigned to a mindfulness or education-only control group in a 1:1 ratio. During the study, all participants will complete six weekly online modules, daily sleep diaries, and optional participation in a treatment-specific online discussion forum. Feasibility outcome measures will include study recruitment, retention, intervention adherence (number of online modules completed, number of meditation days per week), and intervention acceptability (8-item questionnaire). The primary clinical outcome measure will be sleep quality measured with the Pittsburgh Sleep Quality Index. Secondary outcome measures will include sleep measured with actigraphy and diaries (sleep efficiency, total sleep time, total wake time), Patient-Reported Outcomes Measurement Information System (PROMIS) measures (fatigue, sleep-related impairment, sleep disturbance); mood (depression, anxiety, positive affect, quality of life); and self-management and behavior change (potential self-efficacy, self-regulation, sleep problem acceptance, and trait mindfulness). Assessments will occur at baseline and post-intervention; an additional acceptability survey will be completed 4 weeks postpartum. Analyses will examine within-group differences in outcome change scores from baseline to post-intervention. Open-ended feedback will be analyzed using qualitative content analysis.

Discussion

This research is innovative in addressing sleep in pregnancy using a self-management research design and methods that can be accessible and cost-effective for large numbers of pregnant women. The results from this study will inform intervention refinement and efficacy testing of the intervention in a larger randomized controlled trial.

Promoting Health and Well-Being Through Mobile Health Technology (Roadmap 2.0) in Family Caregivers and Patients Undergoing Hematopoietic Stem Cell Transplantation: Protocol for the Development of a Mobile Randomized Controlled Trial

Background

Cancer patients who undergo allogeneic hematopoietic stem cell transplantation are among the most medically fragile patient populations with extreme demands for caregivers. Indeed, with earlier hospital discharges, the demands placed on caregivers continue to intensify. Moreover, an increased number of allogeneic hematopoietic stem cell transplantations are being performed worldwide, and this expensive procedure has significant economic consequences. Thus, the health and well-being of family caregivers have attracted widespread attention. Mobile health technology has been shown to deliver flexible, and time- and cost-sparing interventions to support family caregivers across the care trajectory.

Objective

This protocol aims to leverage technology to deliver a novel caregiver-facing mobile health intervention named Roadmap 2.0. We will evaluate the effectiveness of Roadmap 2.0 in family caregivers of patients undergoing hematopoietic stem cell transplantation.

Methods

The Roadmap 2.0 intervention will consist of a mobile randomized trial comparing a positive psychology intervention arm with a control arm in family caregiver-patient dyads. The primary outcome will be caregiver health-related quality of life, as assessed by the PROMIS Global Health scale at day 120 post-transplant. Secondary outcomes will include other PROMIS caregiver- and patient-reported outcomes, including companionship, self-efficacy for managing symptoms, self-efficacy for managing daily activities, positive affect and well-being, sleep disturbance, depression, and anxiety. Semistructured qualitative interviews will be conducted among participants at the completion of the study. We will also measure objective physiological markers (eg, sleep, activity, heart rate) through wearable wrist sensors and health care utilization data through electronic health records.

Results

We plan to enroll 166 family caregiver-patient dyads for the full data analysis. The study has received Institutional Review Board approval as well as Code Review and Information Assurance approval from our health information technology services. Owing to the COVID-19 pandemic, the study has been briefly put on hold. However, recruitment began in August 2020. We have converted all recruitment, enrollment, and onboarding processes to be conducted remotely through video telehealth. Consent will be obtained electronically through the Roadmap 2.0 app.

Conclusions

This mobile randomized trial will determine if positive psychology-based activities delivered through mobile health technology can improve caregiver health-related quality of life over a 16-week study period. This study will provide additional data on the effects of wearable wrist sensors on caregiver and patient self-report outcomes.

Psychosocial Sequelae of Stroke in Working-Age Adults: A Pilot Study

OBJECTIVE

Few prospective studies have examined psychosocial symptoms in young adult stroke survivors. The purpose of this pilot study was to examine the feasibility of methods to assess and describe the presence of symptoms and their characteristics in young adult stroke survivors.

METHODS

A prospective descriptive design using PROMIS and NeuroQoL patient-reported outcomes was used. Stroke survivors aged 18 to 65 years admitted for acute ischemic stroke completed baseline measures before hospital discharge; the same measures were collected by telephone interview 6 months later.

RESULTS

Thirty patients were recruited, and 18 (60%) completed follow-up measures. There was wide variability in scores across patients for each patient-reported outcome that persisted at 6 months. NeuroQoL cognitive function was the only patient-reported outcome to have a statistically significant change from baseline to 6 months (P = .045).

CONCLUSIONS

It is feasible to recruit and retain young adult stroke survivors in a prospective study. Wide variability in scores across patients suggests different trajectories of recovery in the first 6 months after stroke. Neuroscience nurses can assess for these symptoms and provide individualized interventions to aid in self-management of burdensome symptoms.

PROMIS® and Neuro-QoLTM measures are valid measures of health-related quality of life among patients with familial chylomicronemia syndrome

Background: FCS significantly affects health-related quality of life (HRQOL). Legacy patient-reported outcome measures are often not sensitive to FCS's impact. NIH PROMIS and Neuro-QoL measures may accurately capture HRQOL in FCS patients. This study assessed a broad range of PROMIS and Neuro-QoL measures covering physical, mental, and social HRQOL to determine their suitability for the FCS population.Methods: Adult FCS patients in the United States (N = 25) were recruited to an online survey study and completed several PROMIS short forms and Neuro-QoL computer adaptive tests.Results: Scores were more than 0.5 standard deviations (SD) worse than the normative mean on 10 of 16 normed measures, and more than 0.75 SDs worse than the normative mean on two measures. Responses at the floor and ceiling were occasionally observed, marginal reliabilities were strong, and significant differences across performance status (ps < 0.05) provided preliminary support for construct validity. The measures correlated with each other strongly and as expected.Conclusion: Results support the ability of PROMIS and Neuro-QoL measures to detect HRQOL impairment among patients with FCS. PROMIS and Neuro-QoL measures captured the functional impact and symptom burden associated with FCS, and the broad range of symptom severity experienced by patients with FCS.

Psychosocial interventions for cancer survivors: A meta-analysis of effects on positive affect

PURPOSE

Positive affect has demonstrated unique benefits in the context of health-related stress and is emerging as an important target for psychosocial interventions. The primary objective of this meta-analysis was to determine whether psychosocial interventions increase positive affect in cancer survivors.

METHODS

We coded 28 randomized controlled trials of psychosocial interventions assessing 2082 cancer survivors from six electronic databases. We calculated 76 effect sizes for positive affect and conducted synthesis using random effects models with robust variance estimation. Tests for moderation included demographic, clinical, and intervention characteristics.

RESULTS

Interventions had a modest effect on positive affect (g = 0.35, 95% CI [0.16, 0.54]) with substantial heterogeneity of effects across studies ([Formula: see text]; I² = 78%). Three significant moderators were identified: in-person interventions outperformed remote interventions (P = .046), effects were larger when evaluated against standard of care or wait list control conditions versus attentional, educational, or component controls (P = .009), and trials with survivors of early-stage cancer diagnoses yielded larger effects than those with advanced-stage diagnoses (P = .046). We did not detect differential benefits of psychosocial interventions across samples varying in sex, age, on-treatment versus off-treatment status, or cancer type. Although no conclusive evidence suggested outcome reporting biases (P = .370), effects were smaller in studies with lower risk of bias.

CONCLUSIONS

In-person interventions with survivors of early-stage cancers hold promise for enhancing positive affect, but more methodological rigor is needed.

IMPLICATIONS FOR CANCER SURVIVORS

Positive affect strategies can be an explicit target in evidence-based medicine and have a role in patient-centered survivorship care, providing tools to uniquely mobilize human strengths.

HDQLIFE and neuro-QoL physical function measures: Responsiveness in persons with huntington's disease

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.

Multisystem Resiliency as a Predictor of Physical and Psychological Functioning in Older Adults With Chronic Low Back Pain

Evidence supports the benefits of resilience among older adults with chronic pain. While numerous factors confer resilience, research has largely examined these measures in isolation, despite evidence of their synergistic effects. Conceptualizing resilience from a multisystem perspective may provide a deeper understanding of adaptive functioning in pain. Sixty adults (ages 60+ years) with chronic low back pain completed measures of physical function, pain intensity, disability, and a performance-based task assessing back-related physical functioning and movement-evoked pain (MEP). Depressive symptoms, quality of life, and general resilience were also evaluated. To examine multisystem resiliency, principal components analysis (PCA) was conducted to create composite domains for psychological (positive affect, hope, positive well-being, optimism), health (waist–hip ratio, body mass index, medical comorbidities), and social (emotional, instrumental, informational support) functioning measures, followed by cluster analysis to identify participant subgroups based upon composites. Results yielded four clusters: Cluster 1 (high levels of functioning across psychological, health, and social support domains); Cluster 2 (optimal health and low psychosocial functioning); Cluster 3 (high psychological function, moderate-to-high social support, and poorer health); and Cluster 4 (low levels of functioning across the three domains). Controlling for sociodemographic characteristics, individuals with a more resilient phenotype (Cluster 1) exhibited lower levels of disability, higher quality of life and psychological functioning, and greater functional performance when compared to those with a lower degree of personal resources (Cluster 4). No significant cluster differences emerged in self-reported pain intensity or MEP. These findings signify the presence of resiliency profiles based upon psychological, social, and health-related functioning. Further examination of the additive effects of multiple adaptive behaviors and resources may improve our understanding of resilience in the context of pain, informing novel interventions for older adults.

Race/Ethnicity Moderates the Association Between Psychosocial Resilience and Movement-Evoked Pain in Knee Osteoarthritis

Objective

Racial/ethnic disparities in pain are well‐recognized, with non‐Hispanic blacks (NHBs) experiencing greater pain severity and pain‐related disability than non‐Hispanic whites (NHWs). Although numerous risk factors are posited as contributors to these disparities, there is limited research addressing how resilience differentially influences pain and functioning across race/ethnicity. Therefore, this study examined associations between measures of psychosocial resilience, clinical pain, and functional performance among adults with knee osteoarthritis (OA), and assessed the moderating role of race/ethnicity on these relationships.

Methods

In a secondary analysis of the Understanding Pain and Limitations in Osteoarthritic Disease (UPLOAD‐2) study, 201 individuals with knee OA (NHB = 105, NHW = 96) completed measures of resilience (ie, trait resilience, optimism, positive well‐being, social support, positive affect) and clinical pain, as well as a performance‐based measure assessing lower‐extremity function and movement‐evoked pain.

Results

Bivariate analyses showed that higher levels of psychosocial resilience were associated with lower clinical pain and disability and more optimal physical functioning. NHBs reported greater pain and disability, poorer lower‐extremity function, and higher movement‐evoked pain compared with NHWs; however, measures of psychosocial resilience were similar across race/ethnicity. In moderation analyses, higher optimism and positive well‐being were protective against movement‐evoked pain in NHBs, whereas higher levels of positive affect were associated with greater movement‐evoked pain in NHWs.

Conclusion

Our findings underscore the importance of psychosocial resilience on OA‐related pain and function and highlight the influence of race/ethnicity on the resilience‐pain relationship. Treatments aimed at targeting resilience may help mitigate racial/ethnic disparities in pain.

Health Related Quality of Life in Adult Low and High-Grade Glioma Patients Using the National Institutes of Health Patient Reported Outcomes Measurement Information System (PROMIS) and Neuro-QOL Assessments

Health related quality of life (HRQOL) measures have become increasingly important in the management of glioma patients in both research and clinical practice settings. Functional impairment is common in low-grade and high-grade glioma patients as the disease has both oncological and neurological manifestations. Natural disease history as well as medical or surgical treatment can negatively influence HRQOL. There are no universal standards for HRQOL assessment in glioma patients. In this study, we examine patient perspectives on functional outcome domains and report the prevalence of impairments rates using the National Institutes of Health (NIH) Patient Reported Outcomes Measurement Information System (PROMIS) and Neuro-QOL item banks as measures of HRQOL. Retrospective analysis of a prospectively collected dataset involving 79 glioma patients reveals that quality of life concerns are the most important consideration behind making decisions about treatment in 80.7% of patients. The prevalence of functional impairment by PROMIS and NEURO-QOL assessment is high, ranging from 28.6% in the physical function domain to 43.9% in the cognitive function domain. Pain and anxiety related to physical decline is higher in LGG patients compared to HGG patients. Aphasia severity also impacts HRQOL. The results of this study suggest that the PROMIS and NEURO-QOL assessments may be important HRQOL metrics for future use in larger clinical research and clinical trial settings.

Conceptual Underpinnings of the Quality of Life in Neurological Disorders (Neuro-QoL): Comparisons of Core Sets for Stroke, Multiple Sclerosis, Spinal Cord Injury, and Traumatic Brain Injury

OBJECTIVE

To determine the extent to which the content of the Quality of Life in Neurological Disorders (Neuro-QoL) covers the International Classification of Functioning, Disability and Health (ICF) Core Sets for multiple sclerosis (MS), stroke, spinal cord injury (SCI), and traumatic brain injury (TBI) using summary linkage indicators.

DESIGN

Content analysis by linking content of the Neuro-QoL to corresponding ICF codes of each Core Set for MS, stroke, SCI, and TBI.

SETTING

Three academic centers.

PARTICIPANTS

None.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Four summary linkage indicators proposed by MacDermid et al were estimated to compare the content coverage between Neuro-QoL and the ICF codes of Core Sets for MS, stroke, MS, and TBI.

RESULTS

Neuro-QoL represented 20% to 30% Core Set codes for different conditions in which more codes in Core Sets for MS (29%), stroke (28%), and TBI (28%) were covered than those for SCI in the long-term (20%) and early postacute (19%) contexts. Neuro-QoL represented nearly half of the unique Activity and Participation codes (43%-49%) and less than one third of the unique Body Function codes (12%-32%). It represented fewer Environmental Factors codes (2%-6%) and no Body Structures codes. Absolute linkage indicators found that at least 60% of Neuro-QoL items were linked to Core Set codes (63%-95%), but many items covered the same codes as revealed by unique linkage indicators (7%-13%), suggesting high concept redundancy among items.

CONCLUSIONS

The Neuro-QoL links more closely to ICF Core Sets for stroke, MS, and TBI than to those for SCI, and primarily covers activity and participation ICF domains. Other instruments are needed to address concepts not measured by the Neuro-QoL when a comprehensive health assessment is needed.

How Do Pain, Fatigue, Depressive, and Cognitive Symptoms Relate to Well-Being and Social and Physical Functioning in the Daily Lives of Individuals With Multiple Sclerosis?

OBJECTIVE

To examine the relative association between daily change in pain, fatigue, depressed mood, and cognitive function and 4 outcomes-positive affect and well-being, ability to participate in social roles and activities, upper extremity (UE) functioning, and lower extremity (LE) functioning.

DESIGN

Data analysis, multilevel mixed modeling.

SETTING

General community.

PARTICIPANTS

Ambulatory adults (N=102) with multiple sclerosis.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Customized short-forms of the Quality of Life in Neurological Disorders positive affect and well-being, UE functioning, and LE functioning item banks and the Patient-Reported Outcomes Measurement Information System ability to participate in social roles and activities item bank adapted for daily use and administered as end-of-day diaries.

RESULTS

Above and beyond the effects of demographic and clinical covariates, daily pain was associated with 3 of the 4 outcomes; days of higher than usual pain were related to lower same-day social participation (unstandardized β, B=-1.00; P=.002), UE functioning (B=-1.04; P=.01), and LE functioning (B=-.71; P=.04). Daily fatigue and depressed mood were independently related to daily positive affect and well-being; days of worse fatigue (B=-.54; P=.006) and depressed mood (B=-1.17; P<.0001) were related to lower same-day well-being.

CONCLUSIONS

The results indicate the role of fluctuations in symptoms in daily functioning and quality of life of individuals with multiple sclerosis. Daily increases in pain intensity are related to social and physical functioning, whereas increases in fatigue and depressed mood are related to lower daily well-being. Findings implicate a person-centered approach to monitoring and treating symptoms.

Linking of the quality of life in neurological disorders (Neuro-QoL) to the international classification of functioning, disability and health

BACKGROUND

The quality of life in neurological disorders (Neuro-QoL) is a U.S. National Institutes of Health initiative that produced a set of self-report measures of physical, mental, and social health experienced by adults or children who have a neurological condition or disorder.

OBJECTIVE

To describe the content of the Neuro-QoL at the item level using the World Health Organization's international classification of functioning, disability and health (ICF).

METHODS

We assessed the Neuro-QoL for its content coverage of functioning and disability relative to each of the four ICF domains (i.e., body functions, body structures, activities and participation, and environment). We used second-level ICF three-digit codes to classify items into categories within each ICF domain and computed the percentage of categories within each ICF domain that were represented in the Neuro-QoL items.

RESULTS

All items of Neuro-QoL could be mapped to the ICF categories at the second-level classification codes. The activities and participation domain and the mental functions category of the body functions domain were the areas most often represented by Neuro-QoL. Neuro-QoL provides limited coverage of the environmental factors and body structure domains.

CONCLUSIONS

Neuro-QoL measures map well to the ICF. The Neuro-QoL-ICF-mapped items provide a blueprint for users to select appropriate measures in ICF-based measurement applications.

Neuro-QoL health-related quality of life measurement system: Validation in Parkinson's disease

INTRODUCTION

Neuro-QoL is a multidimensional patient-reported outcome measurement system assessing aspects of physical, mental, and social health identified by neurology patients and caregivers as important. One of the first neurology-specific patient-reported outcome measure systems created using modern test development methods, Neuro-Qol enables brief, yet precise, assessment and the ability to conduct both PD-specific and cross-disease comparisons. We present results of Neuro-QoL clinical validation using a sample of PD patients.

METHODS

A total of 120 PD patients recruited from academic medical centers were assessed at baseline, 1 week, and 6 months. Assessments included Neuro-QoL and general and PD-specific validity measures.

RESULTS

Participants were 62% male and 95% white (average age = 66); H & Y stages were 1 (16%), 2 (61%), 3 (18%), and 4 (5%). Internal consistency and test-retest reliability of Neuro-QoL ranged from Cronbach's alphas = 0.81 to 0.94 with intraclass correlation coefficients = 0.66 to 0.80. Pearson's correlations between Neuro-QoL and legacy measures were generally moderate and in expected directions. UPDRS Part 2 was moderately correlated with Neuro-QoL Upper Extremity and Mobility, respectively (r's = -0.44; -0.59). Parkinson's Disease Questionnaire-39 and Neuro-QoL measures of similar constructs showed strong-to-moderate correlations (r's = 0.70-0.44). Neuro-QoL measures of fatigue, mobility, positive emotion, and emotional/behavioral control showed responsiveness to self-reported change.

CONCLUSIONS

Neuro-QoL is valid for use in PD clinical research. Reliability for all but two measures is sufficient for group comparisons, with some evidence supporting responsiveness to change. Neuro-QoL possesses characteristics, such as brevity, flexibility in administration, and suitability, for cross-disease comparisons that may be advantageous to users in a variety of settings. © 2016 Movement Disorder Society.
