To evaluate the psychometric properties of PROMs for measuring body image in breast cancer patients. In December 2024, a psychometric systematic review was performed in the nine databases. The COSMIN checklist was employed to evaluate the methodological quality and psychometric properties of the included body image measures. The level of evidence was assessed using the GRADE framework, and final recommendations were formulated for the scale. Thirty-eight articles evaluating fifteen PROMs were included in this review. Structural validity, internal consistency, and hypothesis testing had been most frequently evaluated. Measurement error had not been assessed for all PROMs. Twelve instruments show potential application value but require further research. The BAS-BC, PSPP, and ASI-R are not recommended for use, as these instruments do not meet the strict COSMIN thresholds for full recommendation. The BIS can be recommended as a temporary screening tool for assessing body image outcome in clinical practice. The BIRS can be tentatively advised for measuring specific postoperative body image changes. However, further comprehensive studies are required to validate the psychometric properties of existing PROMs. Cancer and its treatment can lead to body image disturbance among breast cancer patients, which may result in lower self-esteem, depression and social withdrawal. Body image has been identified as a critical factor in assessing quality of life in breast cancer patients. Although several instruments have been developed to assess body image in these patients, their measurement properties have not been rigorously evaluated. Healthcare professionals and researchers face challenges in selecting the most suitable body image assessment tool. This review evaluates the psychometric properties of patient-reported outcome measures (PROMs) designed to assess body image in breast cancer patients. Our findings suggest that the Body Image Scale (BIS) can be recommended as a provisional screening tool for assessing body image outcomes, while the Breast Cancer Impact on Body Image Scale (BIRS) can be tentatively recommended for evaluating specific postoperative changes in body image. However, further comprehensive studies are needed to validate the psychometric properties of these existing PROMs.
The Manchester Short Assessment of Quality of Life (MANSA) is a quality-of-life (QOL) instrument developed for people with mental illness. This study aimed to develop a Japanese version of the MANSA for people with severe mental illness (SMI) and examine associations between individual MANSA domains and psychiatric diagnosis. The MANSA includes 12 self-rated subjective QOL items; the overall score is their mean on a 1–7 scale. We prepared a Japanese translation and tested validity and reliability using cross-sectional survey data from 237 adults with SMI in Japan. Concurrent validity was tested in 38 respondents who also completed the WHOQOL26. The sample was randomly split for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) in separate subsamples. Analyses included score distributions, validity, internal consistency, and domain-level ordinal logistic regression. The MANSA items showed the expected associations with the relevant scales and items. Although a two-factor structure was supported by EFA, the CFA fit indices were CFI = 0.86, TLI = 0.82, and RMSEA = 0.12. In the one-factor EFA solution, all factor loadings exceeded 0.40. Cronbach’s alpha for all 12 items was 0.877. The schizophrenia-spectrum group had higher scores in several domains than the bipolar- and depressive-disorder groups, and symptom stability was associated with higher scores across all domains. The Japanese version of MANSA showed acceptable concurrent validity and internal consistency. The proposed two-factor structure was not supported; total-score use remained reasonable, but further validation is needed. Diagnosis and symptom stability were associated with domain-specific QOL. People with severe mental illness need quality-of-life measures that reflect the areas of life most relevant to their experiences. However, Japan has lacked a validated Japanese version of an international mental-health-specific measure. We translated the Manchester Short Assessment of Quality of Life (MANSA) into Japanese and evaluated it in 237 adults receiving treatment for severe mental illness. The Japanese version showed acceptable relationships with other quality-of-life and self-esteem measures and good internal consistency. The overall MANSA score was better supported than the previously proposed two-factor structure. MANSA scores also differed across diagnostic groups, and respondents who reported more stable symptoms had higher scores in every domain. These findings suggest that the Japanese version of MANSA can be used to assess overall and domain-specific quality of life, although its factor structure should be examined further in larger, clinically characterized samples.
Suicidal thoughts and behaviors are associated with severe impairment in daily functioning and reduced quality of life, yet clinical trials of suicide-focused psychotherapies have focused almost exclusively on suicidal ideation and behavior as outcomes. This study examined change in patient-reported functional outcomes (pain interference, physical functioning, and social functioning) during two evidence-based psychotherapy treatments for elevated suicide risk. This is a secondary analysis of a two-arm parallel randomized controlled trial comparing Brief Cognitive Behavioral Therapy (BCBT) and Present-Centered Therapy (PCT) delivered to 85 adults with active suicidal ideation or a recent suicide attempt. Physical functioning, pain interference, and ability to participate in social roles and activities were assessed using the 43-item Patient Reported Outcomes Measurement Information System (PROMIS-43) at baseline and at 3, 6, 9, and 12 months. Generalized estimating equations were used to estimate change over time and between-group differences. Clinically meaningful change was defined as ≥ 5-point PROMIS-43 T-score change [44]. At baseline, functional impairment was prevalent: 50.0
The Dutch Adult Strabismus-20 questionnaire (Dutch-AS-20) is a patient-reported outcome measure (PROM) developed to assess the strabismus-specific quality of life (QoL) in adult patients with strabismus in the Netherlands. This 18-item questionnaire comprises a psychosocial and visual function subscale. The aim of this prospective, multicenter, longitudinal study was to evaluate the responsiveness and determine the minimal important change (MIC) of the Dutch-AS-20 in patients undergoing strabismus surgery. Adult patients scheduled for strabismus surgery were enrolled. The Dutch-AS-20, EQ-5D-5L, Amblyopia and Strabismus Questionnaire (A SQ), Diplopia Questionnaire (DQ) and two global rating of change (GRC) questions were administered pre- and/or postoperatively. We used a construct approach to assess the responsiveness, testing eight pre-specified hypotheses. We determined the MIC using adjusted anchor-based predictive modelling. A total of 136 patients completed the questionnaires at baseline. All pre-specified hypotheses were met, indicating sufficient responsiveness of both subscales of the Dutch-AS-20. We estimated a MIC of 3.1 T-score points for the psychosocial subscale. We could not estimate the MIC for the visual function subscale due to a low correlation with the GRC question. Both subscales of the Dutch-AS-20 are sufficiently responsive to change in strabismus-specific QoL following strabismus surgery. These findings are an important step towards the use of the Dutch AS-20 in both research and clinical practice. Future research is needed to determine a more precise MIC and individual-level statistics for both subscales, in order to improve the interpretability of change scores for both clinical and research purposes.
To develop and validate mapping algorithms that estimate EQ-5D health state utility values (HSUVs) from two diabetes-specific patient-reported outcome measures, the Problem Areas in Diabetes (PAID) and Diabetes Distress Scale (DDS), to support economic evaluations when EQ-5D data are unavailable. Data from 662 adults with diabetes in Germany included PAID-20, DDS-17, and EQ-5D-5L responses. Direct mapping models predicted EQ-5D utilities using Tobit and censored least absolute deviation (CLAD) regressions, while indirect mapping models used proportional and partial proportional odds regressions to predict EQ-5D dimensions. Six model specifications were tested, incorporating PAID and DDS items with covariates (age, sex, diabetes type), with selection of predictors guided by item correlations and backward stepwise procedure to retain statistically relevant variables. Model performance was assessed using a selection of performance metrics including root mean square error (RMSE) and mean absolute error (MAE). Internal validation of the models employed 10-fold cross-validation. The strongest-performing direct mapping models consisted of a model with a selection of PAID-20 items and covariates (Tobit regression; RMSE: 0.159; MAE: 0.117) and a model that incorporated PAID-20, DDS-17, and covariates (CLAD regression; RMSE: 0.146; MAE: 0.09), and a model based on DDS-17 items and covariates (Tobit regression; RMSE: 0.164; MAE: 0.121). Indirect mapping models demonstrated higher prediction errors overall (RMSE: 0.187–0.21; MAE: 0.124–0.141) than their counterparts. We present novel algorithms that enable estimation of EQ-5D utilities from PAID and DDS scores, facilitating economic evaluation in diabetes. Preferred models demonstrated predictive accuracy comparable to published mapping studies. Many people with diabetes experience emotional strain, worries, and frustrations while managing their condition. Two widely used tools that serve to measure how the condition affects their daily life are the Problem Areas in Diabetes (PAID) scale and the Diabetes Distress Scale (DDS). To assess the value of new treatments, researchers and health agencies commonly rely on a measure called EQ‑5D, which summarizes overall health and is used to calculate quality‑of‑life scores important for economic evaluations and treatment choices. However, many diabetes studies collect PAID or DDS but do not collect EQ‑5D, making it difficult to judge the wider impact of treatments. This study set out to solve that problem by creating new algorithms that can estimate EQ‑5D scores from PAID and DDS responses when EQ‑5D was not included in a study. Using data from 662 adults with diabetes in Germany, several versions of these algorithms were tested, and the best ones closely matched people’s actual EQ‑5D scores. Among the different statistical approaches we tested, the models that directly linked both PAID and DDS responses to EQ-5D produced the most accurate predictions. These models performed well across a wide range of health states and closely matched the EQ-5D scores that participants reported. In practice, this enables researchers to generate the health-related quality-of-life information required for economic evaluations, even in studies that collect PAID or DDS but not EQ-5D.
To evaluate the measurement properties of the Patient-Reported Outcome Scale for Peptic Ulcer (PROISCD-PU) and to examine its reliability, validity, responsiveness, and domain-level measurement precision using an integrated framework of Classical Test Theory (CTT) and Generalizability Theory (GT). A total of 300 patients with peptic ulcer were recruited from tertiary hospitals and completed the PROISCD-PU. Classical Test Theory was used to evaluate internal consistency, construct validity, clinical discriminant validity, and responsiveness. Generalizability Theory was applied to identify sources of measurement variance and estimate relative generalizability (Eρ2) and absolute dependability (Φ) coefficients under the observed and alternative item configurations. Because the GT analyses were conducted separately for each domain, the findings were interpreted as evidence of domain-level measurement precision. The PROISCD-PU demonstrated acceptable internal consistency for most domains and satisfactory construct validity, supported by item-domain correlation analyses and structural equation modeling. Clinical discriminant validity was partially supported, with significant differences after Holm–Bonferroni correction observed in the spirituality/belief health domain, general module subtotal, and disease-specific domain. Significant improvements were observed following treatment across all domains and the total scale, with standardized response mean values indicating moderate to large responsiveness. Generalizability analyses showed that person-by-item interaction was the major source of measurement variance. Absolute dependability (Φ) was acceptable for the mental health, social health, and disease-specific domains, whereas comparatively lower Φ coefficients were observed for the physical health and spirituality/belief health domains, indicating priorities for future refinement. The PROISCD-PU demonstrated generally acceptable reliability, validity, responsiveness, and domain-level measurement precision for assessing patient-reported outcomes in peptic ulcer disease. The combined use of Classical Test Theory and Generalizability Theory provides complementary psychometric evidence supporting its application in clinical outcome evaluation and quality-of-life research. Future studies should evaluate longitudinal score stability in clinically stable patients and apply multivariate Generalizability Theory to optimize the reliability and scoring structure of the total composite score.
We examined whether cognitive function statistically accounted for associations between stroke and quality of life (QOL). A cross-sectional survey included adults aged ≥ 60 years in Segamat, Malaysia. Cognition was assessed using the Identification and Intervention for Dementia in Elderly Africans instrument, and QOL was assessed using the WHOQOL-BREF. Stroke survivors were matched 1:3 with non-stroke participants by propensity scores based on age, sex, and education. Stroke status was the exposure, cognition the proposed statistical mediator, and four QOL domains, overall QOL, and overall health the outcomes. Models were adjusted for sociodemographic and vascular factors, accounted for matching and multiple testing, and p < 0.05 was considered statistically significant. Among 596 participants, 149 reported stroke; the mean age was 70.36 years (SD 6.81); 41.6
Most studies on health-related quality of life in vestibular disorders rely on standardized symptom- and function-based assessments. However, these approaches may overlook the meanings individuals attribute to their experiences and the belief systems through which they interpret their condition. To analyze the self-perception of health-related quality of life in people with vestibular disorders, considering the belief systems and personal experiences through which they interpret their health condition. This qualitative phenomenological study conducted 16 semi-structured, in-person interviews with patients diagnosed with vestibular disorders (10 women and 6 men; mean age: 53.8 years) treated at a university clinic. Interviews were audio-recorded and transcribed for inductive interpretive thematic analysis. Rigor was ensured through triangulation, reflexivity, and adherence to COREQ guidelines. The study identified 10 categories grouped into three interrelated dimensions: (1) physical-functional, characterized by persistent bodily instability and loss of automaticity; (2) behavioral-social, involving activity restriction and changes in social participation; and (3) emotional-symbolic, encompassing anxiety, uncertainty, and meaning-making processes. Interpretations related to the body, autonomy, risk, and dependence suggested the presence of belief-related frameworks through which participants understood their symptoms and adaptation to the condition. Health-related quality of life in people with vestibular disorders appears to be a dynamic and multidimensional construct that extends beyond symptom burden alone. The findings suggest that belief-related frameworks may influence how physical limitations, emotional responses, and everyday functioning are experienced and interpreted. These findings support the value of integrative clinical approaches that consider not only functional recovery but also the meanings individuals attribute to their condition.
Quality-of-life and health outcomes research relies on assessment instruments, such as self-report surveys and patient-reported outcome measures, to assess respondents’ standing on latent psychological attributes and experiences, such as pain, fatigue, stress, emotional well-being, social participation, and perceived quality of life. Unlike physiological measures, which record bodily states through calibrated procedures, these instruments are used to infer respondents’ standing on these attributes through respondents’ interpretations of items, response options, and lived experience. Nevertheless, researchers often treat measurement validation of scores from these instruments as a routine psychometric step rather than as an argument for score-based interpretations and decisions. Motivated by recent papers by Hawkins et al. [1] and Gill et al. [2] in Quality of Life Research, it is argued that validity resides not in instruments themselves but in the evidential warrant for interpreting and using scores in specified contexts. Results of investigations of reliability, factor structure, and correlations can support this warrant. However, they cannot explain the meaning of the score or justify their use on their own. Argument-based validation requires researchers to specify interpretations, uses, assumptions, and relevant evidence, including consequences—especially when measures cross languages, cultures, populations, service systems, and policy contexts.
Generic patient-reported outcome measures (PROMs) are increasingly being implemented in health systems for routine outcome measurement. Their ability to screen for anxiety and depression could serve as an added benefit. This study aims to assess the screening ability of selected EQ-5D-5L, EQ-HWB, and PROMIS-10 items for anxiety and depression, using self-reported diagnostic history of these conditions, relative to established PHQ-2 and GAD-2 screeners, in general adult populations across 15 countries. Cross-sectional data from “EuroQol Data for Assessment of Population Health Needs and Instrument Evaluation (EQ-DAPHNIE)” project was used. The following countries were included in the analysis: Argentina, Australia, Brazil, Canada, Chile, China, France, Germany, Japan, Mexico, Netherlands, New Zealand, Spain, the United Kingdom (UK), and the United States (US). A sample size of 4500 was planned per country. Sample quotas for age, sex, income, and urban/rural area were based on census or national data in each country. The performance of specific mental health items of the EQ-5D-5L, EQ-Health and Wellbeing (EQ-HWB), Patient-Reported Outcomes Measurement Information System Scale v1.2 – Global Health (PROMIS-10), Generalized Anxiety Disorder 2-item questionnaire (GAD-2), and Patient Health Questionnaire 2-item version (PHQ-2) were compared to self-reported diagnostic history of anxiety or depression. Performance of EQ-5D-5L, EQ-HWB, PROMIS-10, GAD-2, and PHQ-2 in screening for anxiety and depression was evaluated using area under receiver operating curve (AUROC) analysis A total of 68,419 respondents from 15 countries completed surveys. Brazil had the highest percentage of self-reported anxiety diagnoses (29.6
The goal of the Primary Sclerosing Cholangitis Symptom Assessment Project (PSC-SAP) is to develop reliable and valid PSC symptom measures for use in clinical trials. This article describes the process for customizing PROMIS® Fatigue and PROMIS® Cognitive Function short forms for adults with PSC. Relevant items from the PROMIS item banks were selected by matching findings from concept elicitation interviews. Participants were purposively selected for cognitive interviews if they were symptomatic with PSC-related fatigue or cognitive impairment and met general eligibility for PSC clinical trials. Interviews were recorded, transcribed, and coded. The precision of these PROMIS short forms for PSC to capture fatigue and cognitive function at different levels was analyzed. Participants’ (n = 22) open-ended descriptions of fatigue and cognitive impairment were consistent with prior concept elicitation interviews. From the 95-item PROMIS Fatigue item bank, 13 items were selected that directly aligned with fatigue concepts described during concept elicitation. Data from the cognitive interviews confirmed that both measures possessed strong content validity, with items perceived as clear, relevant, and comprehensive. The PROMIS Fatigue Short Form-PSC exceeded the 0.90 reliability threshold for T-scores between 36 and 79; the PROMIS Cognitive Function Short Form-PSC exceeded the 0.90 threshold between T-scores of approximately 22 and 60. This study demonstrated the strength of PROMIS item banks to design PROMIS Fatigue and Cognitive Function short forms for adults with PSC. Once the psychometric properties of the PROMIS short forms are confirmed, these measures may be used to evaluate symptoms in PSC research and clinical trials.
To examine whether physical activity, iron burden (serum ferritin), and pain intensity are independently associated with multidimensional quality of life (QoL) among adults with beta-thalassemia major (BTM) in the United Arab Emirates. In this cross-sectional study, 250 eligible adults with transfusion-dependent BTM were enrolled from a specialized treatment center and included in the analyses. Participants completed the International Physical Activity Questionnaire–Short Form, the WHOQOL-BREF, and a Numeric Rating Scale for pain. Serum ferritin values were extracted from medical records. Multivariable general linear models were conducted to evaluate associations with WHOQOL-BREF physical, psychological, social, and environmental domain scores, adjusting for age, gender, employment status, chelator use, transfusion/chelation frequency, pain intensity, and serum ferritin. Participants had a mean age of 31.7 ± 7.8 years; 45.6
Colorectal (bowel) cancer and its treatment can seriously affect a person’s quality of life, including physical, social, work‑related, and emotional wellbeing. Young people with colorectal cancer experience worse psychological wellbeing, including marked emotional distress and prominent levels of anxiety. This disease is less common in people under 50, but cases of early‑onset colorectal cancer (EOCRC) are rising around the world. The object of this research was to derive a deeper understanding of the challenges and impact on quality of life faced by EOCRC compared to older patients following a colorectal cancer diagnosis. Recruitment of participants from a larger mixed method project of surviving EOCRC patients from 2013 to 2023 and a matched sample of colorectal cancer patients. 1 Participants invited to take part in an in‑depth semi-structured interview conducted by telephone or virtual meeting and audio taped, transcribed, and analysed using an interpretive phenomenological approach. Twenty participants participated in interviews. Three themes (Headspace, physical impact and future) and eight corresponding sub themes encompassing poorer psychological quality of life, emotional distress and heightened anxiety faced by EOCRC. Barriers in current diagnostic services and treatment pathways more often reported by EOCRC. Older and younger cancer patients highlight a shift from active to passive social roles with both groups reporting substantial reductions in overall quality of life and role functioning, but longer lasting impact for EOCRC, who are focused on family, fertility, career, and survival. A review of current diagnostic services and treatment pathways is required, tailoring care for all patients and importantly address the unique needs of EOCRC. Colorectal (bowel) cancer and its treatment can seriously affect a person’s QoL, including physical, social, work‑related, and emotional wellbeing. It is still less common in people under 50, but cases of early‑onset colorectal cancer are rising around the world. Younger adults are often building careers, forming long‑term relationships, and raising families, so cancer can disrupt their lives in separate ways than it does for older people. Research so far has not fully explored these differences, but this study shows that a colorectal cancer diagnosis and its treatment have a particularly strong negative impact on the QoL of younger patients. Young people with colorectal cancer tend to experience worse psychological wellbeing, including marked emotional distress and elevated levels of anxiety. These findings highlight the need for diagnostic services and treatment pathways to be better tailored to support all people with colorectal cancer, and to specifically address the unique needs of those under 50 years of age.
The European Organisation for Research and Treatment of Cancer’s computerized adaptive test instrument, the EORTC CAT Core, provides dynamic, individualised assessment across 14 health-related quality of life domains, including emotional functioning (EF), which encompasses anxiety and depression. When one of these symptoms is of primary interest, separate scores may better support clinical decision-making and increase measurement sensitivity. The aim here was to evaluate separate item banks for anxiety and depression as potential supplements to the EORTC CAT Core. Responses to 33 candidate EF items from 1,023 cancer patients were available from the original EF item bank project. Expert-based content classification was followed by psychometric analyses, including confirmatory factor analysis (CFA), item response theory (IRT) model calibration and evaluation, differential item functioning (DIF) analyses, and CAT simulations to assess measurement properties of the two item banks. Experts allocated nine items to anxiety and 17 to depression while seven items were judged to assess something else. CFA supported unidimensionality for each item bank. All items demonstrated acceptable IRT model fit, and no DIF of practical relevance was identified. CAT simulations indicated greater measurement precision than fixed 1- and 2-item scales, with potential sample size savings of up to 30
Electronic patient-reported outcomes (ePROs) have shown clinical benefits in oncology. Although widely used for symptom monitoring during and after cancer treatment, their potential to replace existing workflows, such as treatment readiness assessment without a direct clinical encounter, remains underexplored. Real-world evidence on the feasibility, acceptability, and resource implications of such approaches is limited. This study evaluated the implementation and use of an ePRO-based system to support treatment readiness assessments in lung cancer care. A mixed-methods study guided by the RE-AIM framework was conducted in routine lung cancer care at a Danish oncology department. Quantitative data from the ePRO platform and electronic health records were used to assess uptake and questionnaire completion. Qualitative data from field observations and semi-structured patient interviews were used to examine workflow integration, user experiences, and perceived value. Changes in staff time use before and after implementation were estimated by combining registry data, field observations, and staff input. A total of 704 patients completed at least one ePRO questionnaire between December 2020 and March 2024, corresponding to 6,134 completed questionnaires. Treatment-level completion increased from 17.7
Visual analog scales (VAS) serve as brief, informative patient reported outcome measures. The EQ VAS is an important component of EQ-5D instruments but is not currently included in the EQ-HWB-9. This study qualitatively assessed perceptions of alternative VAS constructs and recall periods for potential inclusion alongside the EQ-HWB-9 and quantitatively examined VAS ratings. US adults who were: (1) diagnosed with chronic illness; (2) unpaid caregivers; (3) social care users (e.g., received caregiving, living with disability) completed an online survey and interview where they assessed VAS versions with health, health and wellbeing (HWB), and/or quality of life (QoL), as the specified construct. Participants discussed construct interpretation, appropriateness of recall periods (none, today, past 7 days), and whether these influenced their responses. Interviews were analyzed qualitatively through thematic analysis. Among 34 participants, mean (SD) responses for health, HWB, and QoL were 61.9 (SD = 21.3), 60.9 (SD = 21.8) and 66.4 (SD = 21.5), respectively. All three VAS items were strongly correlated (r = 0.84–0.96). Interpretations of health focused on clinical, physical health more than mental/emotional health, HWB indicated mental/emotional health, and QoL evoked broader assessments encompassing finances or social-relationships. Most participants preferred having no specified recall period, allowing consideration of timeframes relevant to their experiences. Although quantitative results suggested that the constructs of health, HWB, and QoL were similar, qualitative results found that they were perceived differently, highlighting the importance of a mixed-methods approach. Further research in larger samples and other countries could help to inform the extent to which constructs and recall periods affect VAS responses.
To develop a measure of satisfaction with orthoses and prostheses for the Limb Injury Measurement Battery for Quality of Life (LIMB-QOL). Items were developed to assess an individual’s satisfaction with, and emotional and physical assimilation of, an orthosis and/or prosthesis. Items covered topics of satisfaction with device performance and aesthetics as well as user adaptation to a device, including usage, fit, and comfort. A pool of 65 items was administered to 471 individuals in the LIMB-QOL field testing/calibration study. Item response theory was used to evaluate and calibrate the new items. Test–retest reliability after 1–2 weeks was evaluated in a subsample. From the original pool, 39 items were removed for content and 11 items were removed due to differential item functioning by type of injury/limb loss and device (orthosis vs. prosthesis). Following psychometric analysis, 15 items were calibrated as an item bank. These items exhibited acceptable internal consistency (α = 0.95) and fit to a unidimensional model. The final 15-item bank has strong psychometric properties (test–retest reliability α = 0.79), can be administered as a computerized adaptive test or 7-item short form, and is applicable to upper and lower injuries, limb loss and reconstruction, and orthotic and prosthetic device users. The LIMB-QOL Satisfaction with Orthosis/Prosthesis is a reliable measure, with evidence for validity in individuals with a variety of limb-affecting injuries and sudden-onset illnesses, and thus can be used broadly following major extremity trauma, and would be ideal for large-scale monitoring of QOL outcomes, although further evaluation of the validity for individuals with dysvascular or degenerative conditions is needed.
