Validation of PROMIS-29 domain scores among adult burn survivors: A National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System Study

Evaluating the psychometric properties of the simplified Chinese version of PROMIS-29 version 2.1 in patients with hematologic malignancies

The Patient-Reported Outcomes Measurement Information System 29-item Profile version 2.1 (PROMIS-29 V2.1) is a widely utilized self-reported instrument for assessing health outcomes from the patients' perspectives. This study aimed to evaluate the psychometric properties of the PROMIS-29 V2.1 Chinese version among patients with hematological malignancy. Conducted as a cross-sectional, this research was approved by the Medical Ethical Committee of the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (registration number QTJC2022002-EC-1). We employed convenience sampling to enroll eligible patients with hematological malignancy from four tertiary hospitals in Tianjin, Shandong, Jiangsu, and Anhui province in China between June and August 2023. Participants were asked to complete a socio-demographic information questionnaire, the PROMIS-29 V2.1, and the Functional Assessment of Cancer Therapy-General (FACT-G). We assessed the reliability, ceiling and floor effects, structural, convergent discriminant and criterion validity of the PROMIS-29 V2.1. A total of 354 patients with a mean age of 46.93 years was included in the final analysis. The reliability of the PROMIS-29 V2.1 was affirmed, with Cronbach's α for the domains ranging from 0.787 to 0.968. Except sleep disturbance, the other six domains had ceiling effects, which were seen on physical function (26.0%), anxiety (37.0%), depression (40.4%), fatigue (18.4%), social roles (18.9%) and pain interference (43.2%), respectively. Criterion validity was supported by significant correlations between the PROMIS-29 V2.1 and FACT-G scores, as determined by the Spearman correlation test (P < 0.001). Confirmatory factor analysis (CFA) indicated a good model fit, with indices of χ2/df (2.602), IFI (0.960), and RMSEA (0.067). The Average Variance Extracted (AVE) values for the seven dimensions of PROMIS-29 V2.1, ranging from 0.500 to 0.910, demonstrated satisfactory convergent validity. Discriminant validity was confirmed by ideal √AVE values. The Chinese version of the PROMIS-29 V2.1 profile has been validated as an effective instrument for assessing symptoms and functions in patients with hematological malignancy, underscoring its reliability and applicability in this specific patient group.

Moderation Effects of Daily Behavior on Associations Between Symptoms and Social Participation Outcomes After Burn Injury: A 6-Month Digital Phenotyping Study

OBJECTIVE

To examine the moderation effects of daily behavior on the associations between symptoms and social participation outcomes after burn injury.

DESIGN

A 6-month prospective cohort study.

SETTING

Community.

PARTICIPANTS

Twenty-four adult burn survivors.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Symptoms and social participation outcomes were assessed weekly using smartphone surveys, including symptoms of pain (Patient-Reported Outcomes Measurement Information System [PROMIS] Pain Intensity and Pain Interference), anxiety (PROMIS Anxiety), and depression (Patient Health Questionnaire), as well as outcomes of social interactions and social activities (Life Impact Burn Recovery Evaluation [LIBRE] Social Interactions and Social Activities). Daily behaviors were automatically recorded by a smartphone application and smartphone logs, including physical activity (steps, travel miles, and activity minutes), sleep (sleep hours), and social contact (number of phone calls and message contacts).

RESULTS

Multilevel models controlling for demographic and burn injury variables examined the associations between symptoms and social participation outcomes and the moderation effects of daily behaviors. Lower (worse) LIBRE Social Interactions and LIBRE Social Activities scores were significantly associated with higher (worse) PROMIS Pain Intensity, PROMIS Pain Interference, PROMIS Anxiety, and Patient Health Questionnaire-8 scores (P<.05). Additionally, daily steps and activity minutes were associated with LIBRE Social Interactions and LIBRE Social Activities (P<.05), and significantly moderated the association between PROMIS Anxiety and LIBRE Social Activities (P<.001).

CONCLUSIONS

Social participation outcomes are associated with pain, anxiety, and depression symptoms after burn injury, and are buffered by daily physical activity. Future intervention studies should examine physical activity promotion to improve social recovery after burns.

Physical and psychosocial outcomes among burn-injured people with heterotopic ossification: A burn model system study

INTRODUCTION

Heterotopic ossification (HO), or ectopic bone formation in soft tissue, is a not so rare and poorly understood debilitating sequela of burn injury. Individuals developing HO following burn injuries to their hands often experience reductions in mobility, significant contractures, and joint pain. This study identifies demographic characteristics of individuals who develop HO and compares their physical and psychosocial outcomes to the general burn population.

METHODS

Participant demographics, injury characteristics, and PROMIS-29 scores across three time points (discharge, six- and 12- months after injury) were extracted from the Burn Model System National Longitudinal Database representing participants from 2015-2022. Mixed-effects linear regression models were used to compare PROMIS scores across all three longitudinal measurements. Models were adjusted for age, sex, race/ethnicity, HO status, and burn size.

RESULTS

Of the 861 participants with data concerning HO, 33 were diagnosed with HO (3.8% of participants). Most participants with HO were male (n = 24, 73%) and had an average age of 40 + /- 13 years. Participants with HO had significantly larger burn size (49 +/-23% Total Body Surface Area (TBSA)) than those without HO (16 +/-17%). Participants with HO reported significantly worse physical function, depression, pain interference and social integration scores than those without HO. After adjusting for covariables, participants with HO continued to report statistically significantly worse physical function than those without HO. Although physical functioning was consistently lower, the two populations did not differ significantly among psychosocial outcome measures.

CONCLUSIONS

While HO can result in physical limitations, the translation to psychosocial impairments was not evident. Targeted treatment of HO with the goal of maximizing physical function should be a focus of their rehabilitation.

LEVEL OF EVIDENCE

2b TYPE OF STUDY: Symptom Prevalence Study.

Examining the association between military service history and outcomes after burn injury

INTRODUCTION

The association between military service history and long-term outcomes after burn injury is unknown. This study uses data from the Burn Model System National Database to compare outcomes of individuals with and without self-reported military service history.

METHODS

Outcome measures were assessed at 12 months after injury including the Veterans Rand-12 Item Health Survey/Short Form-12, Satisfaction With Life Scale, Patient Reported Outcomes Measure Information System 29, 4-D Itch scale, Post Traumatic Stress Disorder Check List - Civilian Version, self-reported Post Traumatic Stress Disorder, and employment status. This study included 675 people with burns of whom 108 reported a history of military service.

RESULTS

The military service history group was more likely to be older, and male. Those with military service were most likely to be on Medicare insurance and those without military service history were most likely to be on Private Insurance/HMP/PPO. No significant differences were found between those with and without military service history in the outcome measures.

CONCLUSIONS

Further research should examine differences in outcomes between civilians and those with military service history, including elements of resilience and post traumatic growth.

Predictors at 6 and 12 Months for Social Participation Outcome at 24 Months in the Adult Burn Injury Population: A Burn Model System National Database Study

OBJECTIVE

To identify clinical factors (physical and psychological symptoms and post-traumatic growth) that predict social participation outcome at 24-month after burn injury.

DESIGN

A prospective cohort study based on Burn Model System National Database.

SETTING

Burn Model System centers.

PARTICIPANTS

181 adult participants less than 2 years after burn injury (N=181).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Demographic and injury variables were collected at discharge. Predictor variables were assessed at 6 and 12 months: Post-Traumatic Growth Inventory Short Form (PTGI-SF), Post-Traumatic Stress Disorder Checklist Civilian Version (PCL-C), Patient-Reported Outcomes Measurement Information System (PROMIS-29) Depression, Anxiety, Sleep Disturbance, Fatigue, and Pain Interference short forms, and self-reported Heat Intolerance. Social participation was measured at 24 months using the Life Impact Burn Recovery Evaluation (LIBRE) Social Interactions and Social Activities short forms.

RESULTS

Linear and multivariable regression models were used to examine predictor variables for social participation outcomes, controlling for demographic and injury variables. For LIBRE Social Interactions, significant predictors included the PCL-C total score at 6 months (β=-0.27, P<.001) and 12 months (β=-0.39, P<.001), and PROMIS-29 Pain Interference at 6 months (β=-0.20, P<.01). For LIBRE Social Activities, significant predictors consisted of the PROMIS-29 Depression at 6 months (β=-0.37, P<.001) and 12 months (β=-0.37, P<.001), PROMIS-29 Pain Interference at 6 months (β=-0.40, P<.001) and 12 months (β=-0.37, P<.001), and Heat Intolerance at 12 months (β=-4.55, P<.01).

CONCLUSIONS

Post-traumatic stress and pain predicted social interactions outcomes, while depression, pain and heat intolerance predicted social activities outcomes in people with burn injury.

Estimating individual health-related quality of life changes in low back pain patients

BACKGROUND

There is a need to evaluate different options for estimating individual change in health-related quality of life for patients with low back pain.

METHODS

Secondary analysis of data collected at baseline and 6 weeks later in a randomized trial of 749 adults with low back pain receiving usual medical care (UMC) or UMC plus chiropractic care at a small hospital at a military training site or two large military medical centers. The mean age was 31; 76% were male and 67% were White. The study participants completed the Patient-Reported Outcomes Measurement Information System (PROMIS®)-29 v 1.0 physical function, pain interference, pain intensity, fatigue, sleep disturbance, depression, anxiety, satisfaction with participation in social roles, physical summary, and mental health summary scores (T-scored with mean = 50 and standard deviation (SD) = 10 in the U.S. general population).

RESULTS

Reliability estimates at the baseline ranged from 0.700 to 0.969. Six-week test-retest intraclass correlation estimates were substantially lower than these estimates: the median test-retest intraclass correlation for the two-way mixed-effects model was 0. 532. Restricting the test-retest reliability estimates to the subset who reported they were about the same as at baseline on a retrospective rating of change item increased the median test-retest reliability to 0.686. The amount of individual change that was statistically significant varied by how reliability was estimated, and which SD was used. The smallest change needed was found when internal consistency reliability and the SD at baseline were used. When these values were used, the amount of change needed to be statistically significant (p < .05) at the individual level ranged from 3.33 (mental health summary scale) to 12.30 (pain intensity item) T-score points.

CONCLUSIONS

We recommend that in research studies estimates of the magnitude of individual change needed for statistical significance be provided for multiple reliability and standard deviation estimates. Whenever possible, patients should be classified based on whether they 1) improved significantly and perceived they got better, 2) improved significantly but did not perceive they were better, 3) did not improve significantly but felt they got better, or 4) did not improve significantly or report getting better.

PROMIS-25 Reliability and Validity Among Children Living with Burn Injury: A Burn Model System National Database Study

This study examined the reliability and validity of the Patient Reported Outcomes Measurement System (PROMIS)-25, a profile instrument consisting of four-item fixed short forms for six health domains, in children living with burn injury. Data were provided by children participating in a multi-center longitudinal study of outcomes after burn injury. Floor and ceiling effects, unidimensionality, internal consistency, reliability, and differential item functioning (DIF) of the PROMIS-25 Profile v.2.0 were examined. Correlations with other established measures were calculated to assess concurrent validity. Children (n = 256) between the ages of 8-18 years with moderate to severe injury provided responses on PROMIS-25 domains. All PROMIS-25 domains showed high internal consistency. Substantial portions of the sample reported no symptoms (anxiety [58.2%], depressive symptoms [54.6%], fatigue [50.8%], pain [60.1%]). There was a large ceiling effect on peer relationships (46.8%) and physical function mobility (57.5%). One-factor confirmatory factor analyses supported unidimensionality for all domains. Reliability was sufficient for group mean comparisons (>0.8) across at least some trait levels for most domains except fatigue and anxiety. No DIF with respect to burn status was detected when comparing the burn sample to the PROMIS pediatric general U.S. population testing sample. These results provide evidence of reliability and validity of PROMIS-25 scores among children living with burn injury. Reliability of domains was low to moderate and would likely be improved, and ceiling effects reduced for some domains, by administering the PROMIS-37, which includes six items per domain.

Preliminary Exploration of Long-Term Patient Outcomes After Tracheostomy in Burns: A Burn Model System Study

INTRODUCTION

Upper airway management is crucial to burn care. Endotracheal intubation is often performed in the setting of inhalation injury, burns of the face and neck, or large burns requiring significant resuscitation. Tracheostomy may be necessary in patients requiring prolonged ventilatory support. This study compares long-term, patient-reported outcomes in burn patients with and without tracheostomy.

MATERIALS AND METHODS

Data from the Burn Model System Database, collected from 2013 to 2020, were analyzed. Demographic and clinical data were compared between those with and without tracheostomy. The following patient-reported outcomes, collected at 6-, 12-, and 24-mo follow-up, were analyzed: Veterans RAND 12-Item Health Survey (VR-12), Satisfaction with Life, Community Integration Questionnaire, Patient-Reported Outcomes Measurement Information System 29-Item Profile Measure, employment status, and days to return to work. Regression models and propensity-matched analyses were used to assess the associations between tracheostomy and each outcome.

RESULTS

Of 714 patients included in this study, 5.5% received a tracheostomy. Mixed model regression analyses demonstrated that only VR-12 Physical Component Summary scores at 24-mo follow-up were significantly worse among those requiring tracheostomy. Tracheostomy was not associated with VR-12 Mental Component Summary, Satisfaction with Life, Community Integration Questionnaire, or Patient-Reported Outcomes Measurement Information System 29-Item Profile Measure scores. Likewise, tracheostomy was not found to be independently associated with employment status or days to return to work.

CONCLUSIONS

This preliminary exploration suggests that physical and psychosocial recovery, as well as the ability to regain employment, are no worse in burn patients requiring tracheostomy. Future investigations of larger scale are still needed to assess center- and provider-level influences, as well as the influences of various hallmarks of injury severity. Nonetheless, this work should better inform goals of care discussions with patients and families regarding the use of tracheostomy in burn injury.

Post-Burn Psychosocial Outcomes in Pediatric Minority Patients in the United States: An Observational Cohort Burn Model System Study

Racial and ethnic minority burn patients face barriers to longitudinal psychosocial support after injury. Studies utilizing the Burn Model System (BMS) National Database report adult minority patients experience worse psychosocial outcomes in domains such as body image during burn recovery. No study to date has investigated disparities in psychosocial outcomes by racial or ethnic category in the pediatric population using the BMS database. This observational cohort study addresses this gap and examines seven psychosocial outcomes (levels of anger, sadness, depression, anxiety, fatigue, peer relationships, and pain) in pediatric burn patients. The BMS database is a national collection of burn patient outcomes from four centers in the United States. BMS outcomes collected were analyzed using multi-level, linear mixed effects regression modeling to examine associations between race/ethnicity and outcomes at discharge after index hospitalization, and 6- and 12-months post-injury. A total of 275 pediatric patients were included, of which 199 (72.3%) were Hispanic. After burn injury, of which the total body surface area was significantly associated with racial/ethnicity category (p < 0.01), minority patients more often reported higher levels of sadness, fatigue, and pain interference and lower levels of peer relationships compared to Non-Hispanic, White patients, although no significant differences existed. Black patients reported significantly increased sadness at six months (β = 9.31, p = 0.02) compared to discharge. Following burn injury, adult minority patients report significantly worse psychosocial outcomes than non-minority patients. However, these differences are less profound in pediatric populations. Further investigation is needed to understand why this change happens as individuals become adults.

Hungarian PROMIS-29+2: psychometric properties and population reference values

OBJECTIVES

This study aims to assess psychometric properties of the Hungarian PROMIS-29+2 profile measure and provide general population reference values for Hungary.

METHODS

An adult general population sample (n = 1700) completed PROMIS-29+2 v2.1 in an online survey. The following psychometric properties were assessed: floor and ceiling effect, convergent validity with SF-36v1 domains, internal consistency (McDonald's omega), unidimensionality, local independence, monotonicity, graded response model (GRM) fit and differential item functioning (DIF). Age- and gender-specific reference values were established using the US item calibrations.

RESULTS

Depending on scale orientation, high floor or ceiling effects were observed for all domains (25.2-60.7%) except for sleep disturbance. McDonald's omega for domains ranged from 0.87-0.97. Unidimensionality, local independence and monotonicity were supported and the GRM adequately fitted for all but one domains. The sleep disturbance domain demonstrated item misfit, response level disordering and low discrimination ability, particularly for item Sleep116 ('refreshing sleep'). Strong correlations were observed between PROMIS-29+2 and corresponding SF-36 domains (r_s=│0.60│ to │0.78│). No DIF was detected for most sociodemographic characteristics. Problems with physical function, pain interference and social roles tended to increase, whereas problems with anxiety, depression, fatigue and cognitive function declined with age (p < 0.01). In all domains except for cognitive function, more health problems occurred in females than in males (p < 0.001).

CONCLUSION

The Hungarian PROMIS-29+2 shows satisfactory psychometric properties; however, the sleep disturbance domain substantially underperforms that requires further attention. Population reference values were generated that facilitate the interpretation of health outcomes in various patient populations.

Burn Patient Perspectives on Disability Weights and the Philosophy of Disability: A Gap in the Literature

Background

Disability-adjusted life years (DALY) have a ubiquitous presence in academic global health, including attempts to understand the global burden of burn injuries.

Objective

The present scoping review aimed to examine whether disability weights (DWs) were informed by burn patient perspectives and secondarily to determine whether literature indicates which of the three most common philosophical models of disability best aligns with burn patient experiences.

Methods

A review of six databases was conducted and The Critical Appraisal Skills Program (CASP) checklist was utilized.

Results

Out of a total of 764 articles, zero studies solicited patient perspectives of DWs. Four articles contained data that could be extrapolated to patient perspectives on disability. All articles utilized semi-structured interviews of burn survivors and reported thematic elements including return to work, self-image, and social integration. Patients reported similar themes that burn injuries were disabling injuries and instrumentally detrimental, with modulation based on the patient's social circumstances.

Conclusions

This scoping review highlights a significant gap in literature. First, no studies were found directly investigating burn patient perspectives on burn DWs. Current DWs have been derived from expert opinions with limited input from patients. Second, the limited primary patient data gleaned from this review suggest patients consider their injuries as instrumentally detrimental, which aligns most closely with the welfarist view of disability. More explicit investigations into the philosophical model of disability best aligning with burn patient experiences are needed to ground the health economics of burns in sound theory.

Preliminary evaluation of the Chinese version of the patient-reported outcomes measurement information system 29-item profile in patients with aortic dissection

BACKGROUND

The Patient-Reported Outcomes Measurement Information System 29-item Profile (PROMIS-29) has been widely used to measure health outcomes from the patient's perspective. It has not been validated in adults with aortic disease. The aim of this study was to explore the reliability and validity of the Chinese PROMIS-29 among patients undergoing surgery for aortic dissection (AD).

METHODS

A cross-sectional design was applied. Eligible patients completed a questionnaire that contained the PROMIS-29 and legacy measures, including the Short Form-12 Health Survey (SF-12), 8-item Somatic Symptom Scale (SSS-8), Generalized Anxiety Disorder-2 (GAD-2), and Patient Health Questionnaire-2 (PHQ-2). The structural validity of the PROMIS-29 was evaluated using confirmatory factor analysis (CFA). Reliability was evaluated with Cronbach's α. Construct validity was assessed by calculating Spearman's rank correlations and comparing known-group differences.

RESULTS

In total, a sample of 327 AD patients was included in the final analysis. Most of them were male (89%) with a mean age of 52.7 (± 10.3). CFA revealed good model fit of the seven-factor structure within PROMIS-29, as well as most domains in single-factor analysis. Reliability was confirmed with Cronbach's α > 0.90. Correlations between comparable domains of the PROMIS-29 and those of legacy questionnaires and most know-group comparisons were observed as hypothesized.

CONCLUSIONS

This study found evidence for acceptable structural validity, construct validity and internal consistency of the PROMIS-29 in a sample of AD patients. It can be applied to AD survivors by researchers or clinicians, measuring outcomes after surgery and identifying those with worse health status.

Strength of association between body mass index and physical function scores in paediatric burn patients: A National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System study

OBJECTIVE

Increased body weight has been associated with reduced muscle wasting in the early catabolic phase after a severe burn. Yet, overweight and obese non-burn children often exhibit impaired musculoskeletal function, which may lead to poor physical function (PF). We aimed to determine the association between body mass index (BMI) at discharge and self-reported PF and caregiver proxy-reported PF during recovery of burned children.

MATERIALS AND METHODS

This is a retrospective multisite longitudinal study in paediatric burn patients ((8-17 y old at time of burn). PF outcome measures were self-reported mobility, proxy-reported mobility, and upper extremity PF evaluated using PROMIS measures at 6-, 12-, and 24-months after injury. Primary exposure variable was BMI-for-age at discharge.

RESULTS

A total of 118 paediatric patients, aged 11.7 ± 3.3 y, with burns covering 37.6 ± 18.8% of their total body surface area (TBSA) and BMI-for-age of 23.1 ± 5.4 kg/m² at discharge were analyzed. BMI at discharge was not significantly associated with self-reported mobility scores 6 months after burn (beta coefficient =-0.23, p = 0.31), had a positive effect on mobility at 12 months (beta = 0.46, p = 0.05), and no effect at 24 months after injury (beta=-0.10, p = 0.60), when adjusted for burn size. BMI did not have a significant effect on proxy-reported mobility or upper extremity PF.

CONCLUSION

A greater BMI at discharge was associated with improved self-reported PF at 12 months after burn but not at 6 months or 24 months, which suggests a faster recovery of PF in paediatric patients of larger body weight. Our data suggests that a larger body weight does not compromise the recovery of PF after burn.

Self-reported health measures in burn survivors undergoing burn surgery following acute hospitalization: A burn model system national database investigation

INTRODUCTION

Health Related Quality of Life (HRQoL) surveys such as PROMIS-29 may facilitate shared decision-making regarding surgery after burn injury. We aimed to examine whether scar revision and contracture release surgery after index hospitalization was associated with differences in HRQoL.

METHODS

Patient and PROMIS-29 Profile v2.0 data were extracted from the Burn Model System (BMS) at 6-, 12-, and 24-months after burn. PROMIS-29 measures 7 health-related domains. Linear regression was performed to identify associations between independent burn patient variables (e.g. scar-related surgery) and PROMIS-29 scores. Socio-demographic and injury variables were analyzed using logistic regression to determine the likelihood of undergoing burn-related surgery.

RESULTS

Of 727 participants, 201 (27.6%) underwent ≥ 1 scar/contracture operation within 24 months of injury. Number of operations at index hospital admission and range of motion (ROM) deficit at discharge were correlated with an increased likelihood of undergoing subsequent scar/contracture surgery (p < 0.05). Participants undergoing scar/contracture surgery and those that were Medicaid insured reported significantly worse HRQoL for PROMIS domains: anxiety, depression, and fatigue (p < 0.05).

CONCLUSIONS

After adjusting for burn severity and available confounders, participants who underwent scar-related burn reconstructive surgery after index hospitalization reported overall worse Health-Related Quality of Life (HRQoL) in multiple domains.

Psychometric validation of the Korean version of PROMIS 29 Profile V2.1 among patients with lower extremity problems

Background

Patients with lower extremity problems (LEP) commonly experience functional loss, pain, decreased range of motion, inadequacy in daily living activities, and structural change in radiographic evaluations. However, the traditional patient-reported outcome measurement which focused on symptoms, had a limited scope of applicability. This study aimed to validate the psychometric properties of the Korean version of PROMIS-29 Profile v2.1 (K-PROMIS-29 V2.1), a multi-dimensional measure for assessing generic profile health-related quality-of-life (HRQoL) in a sample of patients with lower extremity problems (LEP).

Methods

Participants were recruited from the orthopedic outpatient clinics at the Samsung Medical Center in Seoul, South Korea from September to October 2018. Participants completed a survey questionnaire that included the K-PROMIS-29 V2.1 and the SF-36v2. Principal component analysis (PCA) and confirmatory factor analysis (CFA) and Pearson’s correlations were used to evaluate the reliability and validity of the K-PROMIS-29 V2.1.

Results

A total of 299 participants were enrolled in the study and 258 (86%) completed the study questionnaire. The mean age (SD) of the participants was 56.6 (14.5) and 32.3%, 29.8, and 25.2% of the study participants visited outpatient clinics for foot, knee, and hip problems respectively. The Cronbach’s alpha coefficients of 7 sub-domains in K-PROMIS-29 V2.1 ranged from 0.80 to 0.95, indicating satisfactory internal consistency. In CFA, the goodness-of-fit indices were high (CFI = 0.937 and SRMR = 0.061). High to moderate correlations were found between comparable subscales of the K-PROMIS-29 V2.1 and subscales of the SF-36v2 (r = 0.55–0.70).

Conclusions

The K-PROMIS-29 V2.1 is a reliable and valid measure for assessing a broad range of health-related quality-of-life domains in patients with LEP. It would reflect the real-life symptoms experienced by patients with LEP.
