Development and validation of the patient-reported outcome for older people living with HIV/AIDS in China (PROHIV-OLD)

BackgroundThe involvement of quality of life as the UNAIDS fourth 90 target to monitor the global HIV response highlighted the development of patient-reported outcome (PRO) measures to help address the holistic needs of people living with HIV/AIDS (PLWHA) beyond viral suppression. This study developed and tested preliminary measurement properties of a new patient-reported outcome (PROHIV-OLD) measure designed specifically to capture influences of HIV on patients aged 50 and older in China.MethodsNinety-three older people living with HIV/AIDS (PLWHA) were interviewed to solicit items and two rounds of patient cognitive interviews were conducted to modify the content and wording of the initial items. A validation study was then conducted to refine the initial instrument and evaluate measurement properties. Patients were recruited between February 2021 and November 2021, and followed six months later after the first investigation. Classical test theory (CTT) and item response theory (IRT) were used to select items using the baseline data. The follow-up data were used to evaluate the measurement properties of the final instrument.ResultsA total of 600 patients were recruited at the baseline. Of the 485 patients who completed the follow-up investigation, 483 were included in the validation sample. The final scale of PROHIV-OLD contained 25 items describing five dimensions (physical symptoms, mental status, illness perception, family relationship, and treatment). All the PROHIV-OLD dimensions had satisfactory reliability with Cronbach’s alpha coefficient, McDonald’s ω, and composite reliability of each dimension being all higher than 0.85. Most dimensions met the test-retest reliability standard except for the physical symptoms dimension (ICC = 0.64). Confirmatory factor analysis supported the structural validity of the final scale, and the model fit index satisfied the criterion. The correlations between dimensions of PROHIV-OLD and MOS-HIV met hypotheses in general. Significant differences on scores of the PROHIV-OLD were found between demographic and clinical subgroups, supporting known-groups validity.ConclusionsThe PROHIV-OLD was found to have good feasibility, reliability and validity for evaluating health outcome of Chinese older PLWHA. Other measurement properties such as responsiveness and interpretability will be further examined.

Cultural adaptation and validity evidence of the Student Nurse Stressor-15 (SNS-15) Scale for Brazil.

to carry out the cultural adaptation and evaluation of validity evidence of the Student Nurse Stressor-15 (SNS-15) Scale for use in Brazil. psychometric study, conducted from the stages of translation, synthesis, back-translation, review by a committee of seven experts, pre-test and evaluation of measurement properties with 32 and 238 nursing students, respectively. Descriptive statistics, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA) were performed. The reliability of the instrument was estimated using McDonald's Omega (ω). EFA subsidized the distribution of the fifteen SNS-15 items into four factors. Using AFC, satisfactory fit indices were achieved (Comparative Fit Index = 0.94; Tucker-Lewis Index = 0.93; Root Mean Square Error of Approximation = 0.06; Standardized Root Mean Square Residual = 0.16) and ω = 0.86. the Brazilian version of the SNS-15 presents evidence that confirms its validity and reliability.

A multi-sample evaluation of the measurement structure and function of the modified monetary incentive delay task in adolescents

Interpreting the neural response elicited during task functional magnetic resonance imaging (fMRI) remains a challenge in neurodevelopmental research. The monetary incentive delay (MID) task is an fMRI reward processing task that is extensively used in the literature. However, modern psychometric tools have not been used to evaluate measurement properties of the MID task fMRI data. The current study uses data for a similar task design across three adolescent samples (N = 346 [Agemean 12.0; 44 % Female]; N = 97 [19.3; 58 %]; N = 112 [20.2; 38 %]) to evaluate multiple measurement properties of fMRI responses on the MID task. Confirmatory factor analysis (CFA) is used to evaluate an a priori theoretical model for the task and its measurement invariance across three samples. Exploratory factor analysis (EFA) is used to identify the data-driven measurement structure across the samples. CFA results suggest that the a priori model is a poor representation of these MID task fMRI data. Across the samples, the data-driven EFA models consistently identify a six-to-seven factor structure with run and bilateral brain region factors. This factor structure is moderately-to-highly congruent across the samples. Altogether, these findings demonstrate a need to evaluate theoretical frameworks for popular fMRI task designs to improve our understanding and interpretation of brain-behavior associations.

Development and psychometric evaluation of item banks for memory and attention – supplements to the EORTC CAT Core instrument

BackgroundCancer patients may experience a decrease in cognitive functioning before, during and after cancer treatment. So far, the Quality of Life Group of the European Organisation for Research and Treatment of Cancer (EORTC QLG) developed an item bank to assess self-reported memory and attention within a single, cognitive functioning scale (CF) using computerized adaptive testing (EORTC CAT Core CF item bank). However, the distinction between different cognitive functions might be important to assess the patients’ functional status appropriately and to determine treatment impact. To allow for such assessment, the aim of this study was to develop and psychometrically evaluate separate item banks for memory and attention based on the EORTC CAT Core CF item bank.MethodsIn a multistep process including an expert-based content analysis, we assigned 44 items from the EORTC CAT Core CF item bank to the memory or attention domain. Then, we conducted psychometric analyses based on a sample used within the development of the EORTC CAT Core CF item bank. The sample consisted of 1030 cancer patients from Denmark, France, Poland, and the United Kingdom. We evaluated measurement properties of the newly developed item banks using confirmatory factor analysis (CFA) and item response theory model calibration.ResultsItem assignment resulted in 31 memory and 13 attention items. Conducted CFAs suggested good fit to a 1-factor model for each domain and no violations of monotonicity or indications of differential item functioning. Evaluation of CATs for both memory and attention confirmed well-functioning item banks with increased power/reduced sample size requirements (for CATs ≥ 4 items and up to 40% reduction in sample size requirements in comparison to non-CAT format).ConclusionTwo well-functioning and psychometrically robust item banks for memory and attention were formed from the existing EORTC CAT Core CF item bank. These findings could support further research on self-reported cognitive functioning in cancer patients in clinical trials as well as for real-word-evidence. A more precise assessment of attention and memory deficits in cancer patients will strengthen the evidence on the effects of cancer treatment for different cancer entities, and therefore contribute to shared and informed clinical decision-making.

Chinese CSUQ: Cross-Cultural Adaptation and Evaluation of Measurement Properties

The Computer System Usability Questionnaire is one of the most popular standardized usability questionnaires used to assess the perceived usability of computer software, and it has been rigorously translated into multiple languages. This article aims to complete the cross-cultural adaptation of CSUQ in a Chinese environment and examine the psychometric characteristics. We used the forward–backward translation method to complete the initial translation, and designed the psychometric experiment according to the measurement properties required by the consensus-based standards for the selection of health measurement instruments (COSMIN). The COSMIN risk of bias checklist and updated criteria for good measurement properties were used to examine the Chinese CSUQ. The results demonstrated good performance of the Chinese CSUQ in content validity, internal structure and the remaining measurement properties. The results of the factor analysis revealed a three-factor structure, as well as any discrepancy between the Chinese CSUQ and its original version. Therefore, the Chinese CSUQ can be used confidently by Chinese usability practitioners and also serve as an effective alternative to other standardized usability scales.

Measurement Properties of Patient Reported Outcome Scales: A Systematic Review

CONTEXT Recently a standard set for overall pediatric health outcomes in routine care was developed, which includes patient (or proxy) reported outcome measures (PROMs) for global health, cognitive functioning, and self-efficacy. OBJECTIVES To determine whether the following PROMs have sufficient measurement properties to be used in pediatric routine care: PROMIS Pediatric and Parent Proxy Scale - Global Health 7+2, PROMIS Parent Proxy Short Form - Cognitive Function 7a, and NIH Toolbox Self-Efficacy CAT Ages 13 to 17. DATA SOURCES Embase, Psych INFO, and Web of Science were searched from year of inception of each PROM to May 25, 2020; Medline to October 24, 2022. STUDY SELECTION English, full-text peer-reviewed articles that evaluated measurement properties of included PROMs were eligible. DATA EXTRACTION The COSMIN guideline for systematic reviews was used to appraise eligible studies and synthesize the overall evidence. RESULTS Screening >4000 titles yielded 4 to 6 eligible empirical studies for each PROM. The PROMIS instruments had sufficient content validity with low-quality evidence and at least low-quality evidence for sufficient structural validity and internal consistency. The NIH Toolbox lacked essential evidence for content validity. LIMITATIONS Assessments of measurement properties were based on information reported in the included studies; underreporting might have led to less favorable ratings. CONCLUSIONS The PROMIS instruments assessed in this review measure their intended construct for their targeted age group; clinicians can use these PROMs in pediatric routine care. Additional studies evaluating measurement properties, including content validity, are needed for the NIH Toolbox before it should be recommended for use in clinical practice.

Evaluation of Measurement Properties and Differential Item Functioning in the English and French Versions of the University of California, Los Angeles, Loneliness Scale-6: A Scleroderma Patient-Centered Intervention Network (SPIN) Study.

Loneliness has been associated with poorer health-related quality of life but has not been studied in patients with systemic sclerosis (SSc). The current study was undertaken to examine and compare the psychometric properties of the English and French versions of the University of California, Los Angeles, Loneliness Scale-6 (ULS-6) in patients with SSc during the COVID-19 pandemic. This study used baseline cross-sectional data from 775 adults enrolled in the Scleroderma Patient-Centered Intervention Network (SPIN) COVID-19 Cohort. Reliability and validity of ULS-6 scores overall and between languages were evaluated using confirmatory factor analysis (CFA), differential item functioning (DIF) through the multiple-indicator multiple-cause (MIMIC) model, omega/alpha calculation, and correlations of hypothesized convergent relationships. CFA for the total sample supported the single-factor structure (comparative fit index [CFI] 0.96, standardized root mean residual [SRMR] 0.03), and all standardized factor loadings for items were large (0.60-0.86). The overall MIMIC model with language as a covariate fit well (CFI 0.94, SRMR 0.04, root mean square error of approximation 0.11). Statistically significant DIF was found for 3 items across language (βitem2 =0.14, P < 0.001; βitem4 =-0.07, P=0.01; βitem6 =0.13, P < 0.001), but these small differences were without practical measurement implications. Analyses demonstrated high internal consistency with no language-based convergent validity differences. Analyses demonstrated evidence of acceptable reliability and validity of ULS-6 scores in English- and French-speaking adults with SSc. DIF analysis supported use of the ULS-6 to examine comparative experiences of loneliness without adjusting for language.

Measurement Properties of the Dutch Multifactor Fatigue Scale in Early and Late Rehabilitation of Acquired Brain Injury in Denmark.

Fatigue is a major issue in neurorehabilitation without a gold standard for assessment. The purpose of this study was to evaluate measurement properties of the five subscales of the self-report questionnaire the Dutch Multifactor Fatigue Scale (DMFS) among Danish adults with acquired brain injury. A multicenter study was conducted (N = 149, 92.6% with stroke), including a stroke unit and three community-based rehabilitation centers. Unidimensionality and measurement invariance across rehabilitation settings were tested using confirmatory factor analysis. External validity with Depression Anxiety Stress Scales (DASS-21) and the EQ-5D-5L was investigated using correlational analysis. Results were mixed. Unidimensionality and partial invariance were supported for the Impact of Fatigue, Mental Fatigue, and Signs and Direct Consequences of Fatigue, range: RMSEA = 0.07-0.08, CFI = 0.94-0.99, ω = 0.78-0.90. Coping with Fatigue provided poor model fit, RMSEA = 0.15, CFI = 0.81, ω = 0.46, and Physical Fatigue exhibited local dependence. Correlations among the DMFS, DASS-21, and EQ-5D-5L were in expected directions but in larger magnitudes compared to previous research. In conclusion, three subscales of the DMFS are recommended for assessing fatigue in early and late rehabilitation, and these may facilitate the targeting of interventions across transitions in neurorehabilitation. Subscales were strongly interrelated, and the factor solution needs evaluation.

Tools for measuring client experiences and satisfaction with healthcare in low- and middle-income countries: a systematic review of measurement properties

BackgroundPerspectives of patients as clients on healthcare offer unique insights into the process and outcomes of care and can facilitate improvements in the quality of services. Differences in the tools used to measure these perspectives often reflect differences in the conceptualization of quality of care and personal experiences. This systematic review assesses the validity and reliability of instruments measuring client experiences and satisfaction with healthcare in low- and middle-income countries (LMICs).MethodsWe performed a systematic search of studies published in PubMed, SCOPUS, and CINAHL. This review was reported according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Studies describing the development and psychometric properties of client experience and satisfaction with general health care were included in the review. Critical appraisal of study design was undertaken using the Appraisal tool for Cross-Sectional Studies (AXIS). The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist and Terwee’s criteria were used to appraise the psychometric properties of the included studies. A narrative synthesis approach was used in the interpretation of the findings.ResultsOf the 7470 records identified, 12 studies with 14 corresponding instruments met the inclusion criteria and were included in the final review. No study assessed all the psychometric properties highlighted by the COSMIN criteria. In most instruments, we found evidence that initial development work incorporated client participation. The most evaluated measurement properties were content validity, internal consistency, and structural validity. Measurement error and responsiveness were not reported in any study.ConclusionReliability and validity should be considered important elements when choosing or developing an instrument for professionals seeking an effective instrument for use within the population. Our review identified limitations in the psychometric properties of patient experience and satisfaction instruments, and none met all methodological quality standards. Future studies should focus on further developing and testing available measures for their effectiveness in clinical practice. Furthermore, the development of new instruments should incorporate clients' views and be rigorously tested or validated in studies with high methodological quality.Trial registrationCRD42020150438.

Patient reported outcome measures in childbirth and postpartum maternal quality of life: a protocol for systematic review of measurement properties.

Background: Patient centred healthcare is the corner stone to many healthcare strategies. Patient specific health needs should be at the fore of healthcare improvements and quality measurements. Patient reported outcome measures (PROM) that support real world clinical effectiveness assessments are increasingly being used to highlight domains where there is the greatest scope for change. Objectives: This systematic review aims to identify and evaluate existing patient reported assessment measures/tool(s) that can be used in developing a PROM for postpartum women. We will assess and evaluate their measurement properties in a transparent and structured way in accordance with the COSMIN guidelines. Methods: Methodological guidelines for systematic reviews of PROMs have been developed by the COSMIN initiative and will be followed for this systematic review. A systematic literature review will be performed using PubMed, CINAHL and EMBASE from inception to the present day. Two reviewers independently will judge eligibility, conduct data extraction and assess the methodological quality of each study as per COSMIN guidelines. Inclusion criteria: studies should concern PROM with an aim to evaluate measurement properties in the development or the evaluation of a PROM of interest. Included PROM will focus upon postpartum women assessing morbidity and quality of care. All peer reviewed studies with an assessment tool designed for patient completion will be considered. Exclusion criteria; abstract, letters and non-peer reviewed publications. Studies will be graded on measurement properties and quality of evidence as laid out by COSMIN. All studies and characteristics eligible for inclusion will be summarised and a recommendation to the most suitable measurement tool(s) will be given. Discussion: We will provide a comprehensive description of all available patient reported assessment tools available for childbirth and postpartum quality of life and recommend based on COSMIN guidelines the most suitable instrument(s) available for use.

Instrumentos de autoavaliação da postura corporal: uma revisão de escopo

ABSTRACT Postural therapies use active treatment methods, such as self-correction, to control body segments. The evidence for this practice is established from the comparison of the self-perception of body posture before, during, and after postural education. A scoping review of tools to assess self-perception of body posture, besides encouraging research, may guide professionals while developing treatments. This scoping review aims to identify the existing tools that assess self-perception of body posture, describing their type, measurement properties (validity and reliability), and postural outcomes. The protocol of this review was registered in the Open Science Framework (OSF), DOI: 10.17605/OSF.IO/JGH8U. Studies developing and/or evaluating measurement properties and other study designs using self-perception of static body posture as an assessment method were included. In total, 359 studies were found, of which six were analyzed in this study. They presented two types of tool and their measurement properties were related to validity (n=6) and reliability (n=5). Five studies performed the joint analysis of validity and reliability (83%). Spine position, leg and foot posture, trunk and rib deformity, and postural awareness in general were the assessed postural outcomes. Of the six tools that assess self-perception of body posture, only the SSFS scale can be used in any population. To date, no study found a tool that assesses self-perception of body posture and considers all body segments.

The Swedish version of the Anterior Cruciate Ligament Quality Of Life measure (ACL-QOL): translation and measurement properties

PurposeTo translate the ACL-QOL from English to Swedish and evaluate measurement properties for use after surgical and non-surgical management of anterior cruciate ligament (ACL) injury.MethodsThe ACL-QOL was translated from English to Swedish and data were pooled from 13 cohorts to enable a comprehensive evaluation of measurement properties in line with COSMIN guidelines. We evaluated internal consistency, test–re-test reliability, measurement error, structural validity [confirmatory factor analysis (CFA)], construct validity and responsiveness (hypothesis testing), and floor/ceiling effects. Results were stratified by time since injury (≤ 1.5 years; 2–10 years, 15–25 years; > 30 years) and ACL management strategy [surgical (n = 1163), non-surgical (n = 570)].ResultsThe Swedish ACL-QOL had sufficient internal consistency (total and domain scores) for use in surgically managed (Cronbach’s alpha ≥ 0.744) and non-surgically managed (≥ 0.770) ACL-injured individuals at all time-points. Test–re-test reliability was sufficient [intraclass correlation coefficients: all domains > 0.80, total score 0.93 (95% CI 0.86–0.96)]. The standard error of measurement was 5.6 for the total score and ranged from 7.0 to 10.3 for each domain. CFA indicated sufficient SRMR values when using the total score or five domains; however, CFI and RMSEA values did not meet cut-offs for good model fit. Hypothesis testing indicated sufficient construct validity and responsiveness. Floor effects were negligible and ceiling effects were negligible or minor.ConclusionThe Swedish version of the ACL-QOL has sufficient internal consistency, test–re-test reliability, construct validity and responsiveness, for use in people with ACL injury managed with or without ACL surgery. Model fit could be improved and investigation into the source of misfit is warranted.

Evaluating Measurement Properties of the Adapted Interprofessional Collaboration Scale through Rasch Analysis.

This study aimed to evaluate the validity and reliability of the German and Italian versions of the Interprofessional Collaboration Scale (IPC scale) by applying a Rasch analysis. Data were gathered from 1182 nurses participating in a cross-sectional study in northern Italy. The scale demonstrated good reliability (Cronbach’s alpha = 0.92). Item polarity of all 13 items was positive, indicating good construct validity. However, revising one item would further improve the validity of the scale. Item stability was confirmed for work experience, workplace, age range, the language version, and gender. The analysis, applying a non-classical test theory, confirmed that the IPC scale is a valid and reliable instrument to measure interprofessional collaboration between nurses and physicians.

Improving the Hearing Status Discrimination of the Health Utilities Index, Mark 3: Design of the Hearing Status Classification System.

Redesign the health status classification system of the Health Utilities Index, Mark 3 (HUI-3) "hearing" attribute to improve its discrimination of hearing-impaired health states. Domain and item selection from a previously generated item set guided by a domain and item importance survey, structural independence, and cognitive interviews with patients. Tertiary referral center. Patients with a range of hearing loss severities, etiologies, and treatment experiences participated in the domain and item importance survey (n = 108) and hour-long cognitive interviews (n = 10). Subattributes and levels for the novel Hearing attribute. Domain and item importance was scored on a seven-point Likert scale (1, not at all important; 7, extremely important). Mean domain importance was highest for "speech in noise" (6.21; 95% confidence interval, 5.98-6.43) and lowest for "benefits of hearing loss" (3.46; 95% confidence interval, 3.03-3.89). Domains with moderate or greater ( r ≥ 0.5) domain importance Pearson correlation or construct overlap that interfered with structural independence were combined into single subattributes. Iterative adjustments to instructions, items, and phrasing were guided by cognitive interviews to derive the final instrument with seven subattributes: speech, environmental sounds, localization, listening effort, tinnitus, music, and assistive devices. The novel hearing attribute defines 25,920 unique hearing states. The novel HUI-hearing is part of a comprehensive health utility instrument designed for individuals with hearing loss. Pending derivation of a hearing single attribute utility function and evaluation of measurement properties, our innovative approach could be used to improve health utility measurement for impairments described by any of the other HUI-3 attributes.

Faces Scales for Anxiety and Anger: A National Study of Measurement Properties.

Importance: Faces scales are used worldwide to assess pain, but robust faces scales for anxiety and anger do not exist. These scales are urgently needed, because an estimated two-thirds of patients have difficulty reading written questionnaires. Objective: To develop and evaluate measurement properties of faces scales to monitor two mental health symptoms in US adults (anxiety and anger) in accordance with the COnsensus-based Standards for health Measurement INstruments (COSMIN). Methods: The development process included population identification, scale generation, and pretesting. The evaluation process included assessment of content validity, construct validity, criterion validity, test-retest reliability, and measurement error using 5 order-randomized, positively controlled online survey studies conducted between April and June 2020. We recruited national purposive samples of US adults representative on age, gender, and race. For each faces scale, participants assessed relevance, comprehensibility, and comprehensiveness (study 1, n = 300), strength-of-association (study 2, n = 300), convergent validity against the visual analog scale (VAS; study 3, n = 305), convergent validity against the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires (study 4, n = 1,000), and test-retest reliability and measurement error (study 5, n = 853). Results: The anxiety and anger faces scales showed high relevance (95%–96%), comprehensibility (93%–97%), comprehensiveness (94%–97%), and strength-of-association (74%–96%). We found very high agreement with the VAS (ρ = 0.94–0.95) and high agreement with PROMIS questionnaires (ρ = 0.74–0.79). Scales showed adequate test-retest reliability (intraclass correlation = 0.70–0.78) and measurement error (standard error of measurement = 1.14–1.22). Conclusions: Faces scales to monitor anxiety and anger show adequate measurement properties, including content validity, construct validity, criterion validity, test-retest reliability, and measurement error. The recommended use is non-diagnostic monitoring of anxiety and anger, particularly when mental health is an ancillary but important outcome of treatment.

Evaluating measurement properties of subjective cognitive decline self-reported outcome measures: a systematic review

BackgroundSubjective cognitive decline (SCD) is present in the early stage of preclinical Alzheimer’s disease (AD) and is associated with an increased risk of further cognitive decline and AD dementia later in life. Early detection of at-risk groups with subjective complaints is critical for targeted dementia prevention at the earliest. Accurate assessment of SCD is crucial. However, current measures lack important psychometric evaluations and or reporting.ObjectivesTo systematically evaluate measurement properties of self-reported outcome measures (PROMs) used to assess SCD in the older adult population with or at risk of AD.Methods and analysisWe used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols 2015 Checklist for reporting. We conducted a literature search, screened, and included validation studies of SCD based on self-reported questionnaires from both population-based and clinical studies, conducted in older adults (≥ 55). We critically appraised the included primary studies using the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines.ResultsSixteen studies met the inclusion criteria. The included studies reported psychometric properties of 17 SCD self-reported questionnaires. We extracted data on the structural validity, internal consistency, test-retest reliability, and cross-cultural validity and found a widespread proneness to bias across studies, and a marked heterogeneity is assessed and reported measurement properties that prevented the consolidation of results.ConclusionOur findings suggest that available SCD questionnaires lack content validity evaluation. Currently available measurements of SCD lack development and validation standards. Further work is needed to develop and validate SCD self-reported measurement with good quality measurement properties.

Measurement Properties of Aerobic Capacity Measures in Neuromuscular Diseases: A Systematic Review.

ObjectiveTo systematically evaluate the measurement properties of aerobic capacity measures in neuromuscular diseases.Data sourcesMEDLINE, EMBASE, SportDiscus and Web of Science Conference Proceedings Citation Index – Science were systematically searched from inception until 30 June 2021.Study selection and data extractionScreening, data extraction, risk of bias assessment and quality assessment were performed by 2 independent researchers. Studies were included if they evaluated measurement properties of aerobic capacity measures in adults with neuromuscular diseases. Risk of bias was assessed using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist. Results were pooled and the quality of the evidence was determined using a modified Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach.Data synthesisNine studies including 187 participants were included in this review. Low quality of evidence was found for sufficient content validity of peak oxygen consumption through maximal exercise testing. Criterion validity of 4 out of 7 different measures to predict peak oxygen consumption was sufficient; however, quality of evidence was low or very low for all measures. No studies were found evaluating reliability or responsiveness.ConclusionThere was a lack of high-quality studies with sufficiently large sample sizes that evaluated the measurement properties of aerobic capacity measures in neuromuscular diseases.LAY ABSTRACTAerobic capacity (or cardiovascular endurance) is an important outcome measure in exercise intervention studies and pharmacological trials in neuromuscular diseases. To establish the effects of these interventions it is important to use outcome measures with good measurement properties. This means that outcome measures are accurate (valid), repeatable (reliable) and able to detect change over time (responsive). The aim of this study was to review the scientific literature regarding the measurement properties of aerobic capacity measures in neuromuscular diseases. Nine small studies (4–44 participants) reporting on the validity of 8 aerobic capacity measures were found. Five of these measures were judged as valid, but the quality of evidence was low. There were no studies evaluating reliability and responsiveness. Taken together, these results were considered insufficient to make recommendations. High-quality studies, with more participants and a focus on reliability and responsiveness, are required.
