Italian Validation of the Pittsburgh Sleep Quality Index (PSQI) in a Population of Healthy Children: A Cross Sectional Study.

Background: Sleep disorders are one of the most discussed topics in scientific literature every year. Although they are one of the most studied topics, in both adults and children, knowledge of sleep disorders and their treatment is still not completely clear, and there is a need to deepen and analyze these disorders on a country-by-country basis. However, research in the Italian literature reveals a scarce quantity of tools to evaluate sleep quality in children. The Pittsburgh Sleep Quality Index (PSQI) is probably the most commonly used retrospective self-assessment questionnaire in the adult population. Purpose: We aimed to validate and analyze the psychometric characteristics of this tool in order to detect and explore the presence of sleep disorders in a healthy Italian population of children throughout the country. Methods: Individuals aged between 3 and 16 years without symptoms of insomnia were included in this study. The reliability and construct validity of the PSQI were assessed according to Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines. Results: We enrolled 222 individuals in this study (mean age 11 years). The PSQI demonstrated good internal consistency (Cronbach’s α = 0.719). Test–retest reliability was assessed on a randomized subgroup of the sample (n = 35). The PSQI showed good test–retest reliability with an intraclass correlation coefficient of 0.829 for the total score (95% confidence interval: 0.662–0.914). The Pearson correlation coefficient, used for construct validity, showed a statistically significant positive correlation with the Sleep Disturbance Scale for Children (SDSC). Conclusion: The PSQI proved to be a very reliable and valid tool to investigate sleep experiences in children.

Vitiligo International Task force for an Agreed List of core data (VITAL): study protocol of a vitiligo core outcome set (COS) and contextual factors for clinical trials, registries, and clinical practice

BackgroundThere is a lack of consensus related to the collection of standardized data for individuals with vitiligo enrolled in clinical trials and registries as well as those seen in clinical practice which causes difficulty in accurately interpreting, comparing, and pooling of data.Several years ago, efforts to initiate work on developing core outcome sets were performed and a consensus was reached in 2015 on the first core domain set for vitiligo clinical trials.Methods/designThis project aims to further develop a core outcome set for vitiligo clinical trials as well as create internationally agreed-upon core outcome sets for registries and clinical practice. These core outcome sets will include a core domain set and a core measurement instruments set and will be supplemented by contextual factors, including baseline and treatment-related characteristics. In a preparatory exercise, the 2015 core domain set will be re-evaluated and will serve as the basis for the list of outcome domains used to initiate the consensus process. This project will consist of two parts. Part 1 will focus on the selection of a core domain set, or “what to measure” and contextual factors, for each setting based on electronic surveys (e-Delphi technique) and a conclusive consensus meeting by a large group of international stakeholders. Part 2 will include selection of core measurement instruments, or “how to measure,” and measurement details (e.g., scale and timing) for the core domain sets and contextual factors agreed upon in part 1. Part 2 will be based on consensus meetings with stakeholders involved in part 1 and will be guided by C3 (CHORD-COUSIN Collaboration), Harmonising Outcome Measures for Eczema (HOME), COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN), and Outcome Measures in Rheumatology (OMERACT) recommendations including information on measurement properties of available instruments (systematic review and expert/patient opinion). At the end of part 2, all stakeholders involved will be invited to participate in a final meeting in which the ultimate core data sets (core outcome sets and contextual factors) will be presented and the dissemination plan and implementation goals will be defined.DiscussionThis project will harmonize data collection between clinical trials, registries, and clinical practices, facilitating new insights in vitiligo.Trial registrationThis study is registered in the Core Outcome Measures for Effectiveness Trials (COMET) database and on the C3 (CHORD-COUSIN Collaboration) website.

188 Patient-reported outcome measures for health-related quality of life in acne vulgaris: A systematic review of measure development and measurement properties

While multiple patient-reported outcome measures (PROMs) for health-related quality of life exist for patients with acne vulgaris, little is known about the validity of the development and measurement properties of these PROMs. A systematic review was conducted following the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) framework. Data were extracted on PROM properties (target population, domains measured, recall period, development language, number of items), COSMIN-based development and pilot study grading, content validity score (relevance, comprehensiveness, comprehensibility, overall), and measurement properties (structural validity, internal consistency, reliability, construct validity, responsiveness, measurement error, and responsiveness).

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.

Evaluation of psychometric properties of patient-reported outcome measures frequently used in narcolepsy randomized controlled trials: a systematic review.

Study ObjectivesTo systematically determine subjective and objective outcome measures used to measure the efficacy of narcolepsy interventions in randomized controlled trials (RCTs) in adults and children and assess psychometric properties of patient-reported outcome measures (PROMs) used.MethodsWe searched bibliographical databases and clinical trial registries for narcolepsy RCTs and extracted objective and subjective outcome measures. If PROMs were used, we searched for psychometric studies conducted in a narcolepsy population using bibliographical databases and appraised using Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines.ResultsIn total, 80 different outcome measures were used across 100 RCTs. Epworth Sleepiness Scale (ESS) (n = 49) and Maintenance of Wakefulness Test (n = 47) were the most frequently used outcome measures. We found 19 validation studies of 10 PROMs in narcolepsy populations. There was limited evidence for validity or responsiveness of the ESS; yet sufficient reliability (pooled ICC: 0.81–0.87). Narcolepsy Severity Scale (NSS) had sufficient reliability (pooled ICC: 0.71–0.92) and both adult and pediatric versions had sufficient discriminant validity (treated/untreated). Content validity was only evaluated in pediatric populations for ESS-CHAD and NSS-P and rated inconclusive. Quality of evidence of the psychometric studies for all scales ranged from very low to low.ConclusionsAlthough recognized by regulatory bodies and widely used as primary outcome measures in trials, there is surprisingly little evidence for the validity, reliability, and responsiveness of PROMs frequently used to assess treatment efficacy in narcolepsy. The field needs to establish patient-centered minimal clinically important differences for the PROMs used in these trials.

Outcome measurement instruments in Rett syndrome: A systematic review.

The aim of the study was to identify and characterize outcome measures for objective and subjective assessment in persons with Rett syndrome (RS). A systematic review was conducted consulting the EBSCO, Cochrane, Web of Science, Scielo, MEDLINE and PsycINFO databases for published studies describing the use of patient-reported outcome measures (PROMs) and other outcome measures in persons with RS. Validation studies and observational studies were included. The PROMs were first described, and then the measurement properties were evaluated using predefined criteria according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN). The outcome measures were then grouped according to the International Classification of Functioning, Disability and Health (ICF) to establish a relationship between outcome measures and ICF domains. Twenty out of 2327 articles were appraised, and seventeen different outcome measures were identified and described. Ten outcome measures corresponded to evaluation questionnaires, while the remaining seven assessed functional outcomes: walking distance, physical activity level and ability to interact visually. A relation between these outcome measures that assess RS and the ICF allows understanding that most of the instruments (fifteen) include the assessment of activity limitations. The findings of this study seem to be promising for their use by clinicians and researchers, although they have methodological limitations. The accuracy and quality of these individual outcome measures should continue to be assessed in an attempt to gather a consensus on the best tools used in RS.

Psychometric Properties of Disaster Preparedness Tools in Nurses: A Systematic Literature Review.

There is no widely-recommended standardized and valid measurement tool for evaluating the disaster preparedness of nurses. This study aims to assess the psychometric properties of scales developed or adapted to evaluate the sudden-impact natural disaster preparedness of nurses. This study is a systematic literature review for the psychometric properties of disaster preparedness tools. Studies published from 2010 through June 2021 were identified from a systematic search of five databases, including Web of Science, PubMed, CINAHL, Scopus, and ProQuest. The Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist was used for the systematic review and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline for reporting. The World Health Organization's (WHO) report on the Development of a Disaster Preparedness Tool Kit for Nursing and Midwifery was used to evaluate scale contents. Six articles were identified that met the inclusion criteria. The scales generally had a multi-dimensional structure and used Likert scoring with internal consistency coefficients ranging from 0.785 to 0.97. All scales were rated sufficient in content validity, structural validity, and cross-cultural validity. One scale was rated sufficient in criterion validity while the others were rated indeterminate. One scale was rated insufficient in reliability and internal consistency while the others were rated sufficient. The findings suggest improving the psychometric properties of scales of nurses' disaster preparedness according to COSMIN, expanding their content scope, and developing new scales. The study will provide beneficial data to users and researchers regarding the need for a comprehensive assessment tool in determining the disaster preparedness of nurses.

Initial Development and Evaluation of the My Family's Accessibility and Community Engagement (MyFACE) Tool for Families of Children With Disabilities.

Parental perceptions and experiences of community inclusion influence the community participation of families and children with a disability, although no measurement tools exist. To describe the initial development of the My Family's Accessibility and Community Engagement (MyFACE) tool. MyFACE measures parental perceptions of community accessibility and engagement of families raising a child with a disability. Items represent common community activities rated on a 5-point Likert scale. COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guided content validity, construct validity, and internal reliability testing. Australia. Seventy-seven mothers of children with a disability provided data, with 69 complete data sets. The nine-item MyFACE had excellent content and construct validity and good internal reliability (Cronbach's α = .85). Hypothesis testing correlated MyFACE with maternal factors (mental health and healthy behavior) and child factors (psychosocial issues). Three predictors together explained 27% of the variance in a significant model, F(3, 61) = 7.09, p < .001. The most important predictor was maternal depressive symptoms. Initial evaluation of the MyFACE tool suggests sound psychometric properties warranting further development. What This Article Adds: The MyFACE tool provides clinicians and researchers with a way to measure parental perceptions of community inclusion. Maternal depressive symptoms were predictive of MyFACE scores, indicating that to be effective, family participation may require clinicians to address maternal mental health and children's participation restrictions.

Assessment of Patient-Reported Outcome Measures for Maternal Postpartum Depression Using the Consensus-Based Standards for the Selection of Health Measurement Instruments Guideline

Maternal depression is frequently reported in the postpartum period, with an estimated prevalence of approximately 15% during the first postpartum year. Despite the high prevalence of postpartum depression, there is no consensus regarding which patient-reported outcome measure (PROM) should be used to screen for this complex, multidimensional construct. To evaluate psychometric measurement properties of existing PROMs of maternal postpartum depression using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guideline and identify the best available patient-reported screening measure. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. PubMed, CINAHL, Embase, and Web of Science were searched on July 1, 2019, for validated PROMs of postpartum depression, and an additional search including a hand search of references from eligible studies was conducted in June 2021. Included studies evaluated 1 or more psychometric measurement properties of the identified PROMs. A risk-of-bias assessment was performed to evaluate methods of each included study. Psychometric measurement properties of each PROM were rated according to COSMIN criteria. A modified Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess the level of evidence supporting each rating, and a recommendation class (A, recommended for use; B, further research required; or C, not recommended) was given based on the overall quality of each included PROM. Among 10 264 postpartum recovery studies, 27 PROMs were identified. Ten PROMs (37.0%) met the inclusion criteria and were used in 43 studies (0.4%) involving 22 095 postpartum women. At least 1 psychometric measurement property was assessed for each of the 10 validated PROMs identified. Content validity was sufficient in all PROMs. The Edinburgh Postnatal Depression Scale (EPDS) demonstrated adequate content validity and a moderate level of evidence for sufficient internal consistency (with sufficient structural validity), resulting in a recommendation of class A. The other 9 PROMs evaluated received a recommendation of class B. The findings of this systematic review suggest that the EPDS is the best available patient-reported screening measure of maternal postpartum depression. Future studies should focus on evaluating the cross-cultural validity, reliability, and measurement error of the EPDS to improve understanding of its psychometric properties and utility.

Patient-Reported Outcome Measures for Health-Related Quality of Life in Patients With Acne Vulgaris

Multiple patient-reported outcome measures (PROMs) for health-related quality of life (HRQoL) exist for patients with acne. However, little is known about the content validity and other measurement properties of these PROMs. To systematically review PROMs for HRQoL in adults or adolescents with acne. Eligible studies were extracted from PubMed and Embase (OVID). Full-text articles published in English or Spanish on development, pilot, or validation studies for acne-specific, dermatology-specific, or generic HRQoL PROMs were included. Development studies included original development studies, even if not studied in acne patients per Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) recommendations. If a study included several diagnoses, the majority (ie, over 50%) of patients must have acne or acne-specific subgroup analyses must be available. Abstract and full-text screening was performed by 2 independent reviewers. Two independent reviewers assessed study quality applying the COSMIN checklist and extracted and analyzed the data. For each distinctive PROM, quality of evidence was graded by measurement property. PROM properties (target population, domains, recall period, development language), PROM development and pilot studies, content validity (relevance, comprehensiveness, comprehensibility), and remaining measurement properties (structural validity, internal consistency, cross-cultural validity, reliability, measurement error, criterion validity, construct validity, and responsiveness). Quality of evidence was assigned for each measurement property of included PROMs. An overall recommendation level was assigned based on content validity and quality of the evidence of measurement properties. We identified 54 acne PROM development or validation studies for 10 acne-specific PROMs, 6 dermatology-specific PROMs, and 5 generic PROMs. Few PROMs had studies for responsiveness. The only acne-specific PROMs with sufficient evidence for content validity were the CompAQ and Acne-Q. Based on available evidence, the Acne-Q and CompAQ can be recommended for use in acne clinical studies. Two PROMs can currently be recommended for use in acne clinical studies: the Acne-Q and CompAQ. Evidence on content validity and other measurement properties were lacking for all PROMs; further research investigating the quality of remaining acne-specific, dermatology-specific, and generic HRQoL PROMs is required to recommend their use.

Measurement Properties of Remotely or Self-Administered Lower Extremity Mobility Performance Measures in Adults: A Systematic Review.

For individuals who face barriers to care assessment, there is a need for remote administration or self-administration of physical performance measures that assess mobility to determine current functional status and to monitor and predict future changes in functional status. The primary purpose of this review is to evaluate the available measurement properties of scores for remotely or self-administered lower extremity mobility performance measures in adults. This review also outlines the test procedures and population suitability of these measures. Data sources were Ovid MEDLINE, Ovid Embase, EBSCOhost CINAHL, Ovid AMED, and Cochrane CENTRAL-which were searched from inception to January 26, 2021-and the reference lists of relevant studies. Two individuals independently screened studies that assessed at least 1 prespecified measurement property of scores for a remote and/or self-administered lower extremity physical performance measure assessing mobility in an adult population. Two individuals independently extracted data on study characteristics, measurement properties, feasibility, and interpretability using piloted extraction forms. The COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) Risk of Bias tool was used to assess methodological quality. Data were qualitatively summarized, and results were compared against COSMIN's criteria for good measurement properties. Level of evidence was determined using COSMIN's modified GRADE approach. Fourteen studies detailing 19 outcome measures were included. Many studies displayed "sufficient" measurement properties based on COSMIN's criteria; however, risk of bias for most of the included studies was rated adequate or doubtful. Clinicians and researchers can consider the measurement properties of scores and feasibility of different approaches presented in this review when determining how to assess or monitor mobility in adult populations. Assessing mobility via remote or self-administered physical performance measures in adult populations appears to be feasible using a variety of methods including simple tools (chair, stopwatch), videoconferencing, and smartphone applications. This strategy may be particularly valuable for self-management of chronic conditions and decreasing barriers to accessing care.

Practicable performance-based outcome measures of trunk muscle strength and their measurement properties: A systematic review and narrative synthesis.

IntroductionThe evaluation of muscle strength is frequently used as part of the physical examination process, with decreased trunk muscle strength reported in individuals with spinal disorders (e.g., low back pain). Access to practicable performance-based outcome measures (PBOM) to monitor patients’ progress in spinal rehabilitation is essential. Knowledge of the psychometric properties of the available practicable PBOM for trunk strength evaluation is therefore needed to inform practitioners and further research.ObjectiveTo synthesise evidence on the measurement properties of practicable measures of trunk muscle strength in adults with and without musculoskeletal pain.MethodsFollowing a published and registered protocol [PROSPERO CRD42020167464], databases were searched from the database inception date up to 30th of June 2021. Citations and grey literature were also searched. Eligibility criteria comprised: 1) studies which examined the psychometric properties of the trunk strength outcome measures, 2) included adults ≥ 18 years, either asymptomatic or with spinal musculoskeletal pain. Non-English language studies were excluded. Two independent reviewers evaluated the quality and synthesized the data from included studies according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist. The overall quality of evidence was evaluated using a modified Grading of Recommendations Assessment Development and Evaluation (GRADE).ResultsFrom 34 included studies, 15 different PBOMs were identified that have been investigated for reliability and validity, none evaluated responsiveness. In asymptomatic individuals, high quality evidence supports intra-rater reliability of digital-loading cells and moderate quality evidence supports the criterion validity of the hand-held dynamometer. Very low quality evidence exists for the reliability and validity estimates of testing tools among individuals with spinal pain.ConclusionsFindings underpin a cautious recommendation for the use of practicable PROMs to evaluate muscle strength in individuals with spinal pain in clinical practice due to the level of evidence and the heterogeneity of the protocols used. Further high quality research to explore the psychometric properties of the practicable PBOMs with detailed methodology is now needed.

Measurement properties of performance-based measures to assess physical function in knee osteoarthritis: A systematic review

Objective To systematically review the measurement properties of performance-based measures to assess physical function in people with knee osteoarthritis. Data sources PubMed, Web of Science, Embase, Scopus, CINAHL, and PsycINFO were searched in May 2022. Methods This study was conducted in accordance with the guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Clinical trials on the psychometric properties of performance-based tools for measuring physical function in people with knee osteoarthritis were included. Two reviewers independently rated measurement properties using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). “Best evidence synthesis” was made using COnsensus-based Standards for the selection of health Measurement INstruments outcomes and the quality of findings. Results Thirty-six out of 3425 publications were eligible for inclusion. Thirty-two performance-based measures were evaluated including 26 single-activity measures and 6 multi-activity measures. Measurement properties evaluated included internal consistency (2 measures), reliability (23 measures), measurement error (20 measures), hypotheses testing for construct validity (22 measures), and responsiveness (23 measures). On balance of the limited evidence, the walk 40 m fast-paced test and 6-minute walking test were the best rated walking tests. The 30-second chair stand test and timed up and go test were the best rated sit-to-stand tests. The Performance Tests Measures and Physical Activity Restrictions may be the suitable multi-activity measures for knee osteoarthritis. Conclusions Further good quality research investigating the measurement properties, and in particular, the measurement error of performance-based measures in patients with knee osteoarthritis is needed.

Study protocol for developing, piloting and disseminating the PRISMA-COSMIN guideline: a new reporting guideline for systematic reviews of outcome measurement instruments

BackgroundSystematic reviews of outcome measurement instruments are important tools in the evidence-based selection of these instruments. COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) has developed a comprehensive and widespread guideline to conduct systematic reviews of outcome measurement instruments, but key information is often missing in published reviews. This hinders the appraisal of the quality of outcome measurement instruments, impacts the decisions of knowledge users regarding their appropriateness, and compromises reproducibility and interpretability of the reviews’ findings. To facilitate sufficient, transparent, and consistent reporting of systematic reviews of outcome measurement instruments, an extension of the PRISMA (Preferred Reporting of Items for Systematic reviews and Meta-Analyses) 2020 guideline will be developed: the PRISMA-COSMIN guideline.MethodsThe PRISMA-COSMIN guideline will be developed in accordance with recommendations for reporting guideline development from the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network. First, a candidate reporting item list will be created through an environmental literature scan and expert consultations. Second, an international Delphi study will be conducted with systematic review authors, biostatisticians, epidemiologists, psychometricians/clinimetricians, reporting guideline developers, journal editors as well as patients, caregivers, and members of the public. Delphi panelists will rate candidate items for inclusion on a 5-point scale, suggest additional candidate items, and give feedback on item wording and comprehensibility. Third, the draft PRISMA-COSMIN guideline and user manual will be iteratively piloted by applying it to systematic reviews in several disease areas to assess its relevance, comprehensiveness, and comprehensibility, along with usability and user satisfaction. Fourth, a consensus meeting will be held to finalize the PRISMA-COSMIN guideline through roundtable discussions and voting. Last, a user manual will be developed and the final PRISMA-COSMIN guideline will be disseminated through publications, conferences, newsletters, and relevant websites. Additionally, relevant journals and organizations will be invited to endorse and implement PRISMA-COSMIN. Throughout the project, evaluations will take place to identify barriers and facilitators of involving patient/public partners and employing a virtual process.DiscussionThe PRISMA-COSMIN guideline will ensure that the reports of systematic reviews of outcome measurement instruments are complete and informative, enhancing their reproducibility, ease of use, and uptake.

Validation of the Collaborative Practice Assessment Tool (CPAT) to assess the degree of inter-professional collaboration (IPC) in a Community Hospital in Singapore

The Collaborative Practice Assessment Tool (CPAT) is a self-administered questionnaire that can be used to measure the degree of inter-professional collaboration (IPC) within a healthcare team. However, the CPAT has not been validated in Singapore, and there is currently no validated instrument to measure the degree of IPC among healthcare professionals in Singapore. To validate the CPAT in a community hospital (CH) in Singapore. Data was collected prospectively from 148 participants from a CH in Singapore from October 2019 to April 2020. Using the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) framework, we assessed content validity, construct validity, internal consistency and test-retest reliability of the CPAT. We started by assessing content validity through cognitive interviews with healthcare professionals. We assessed construct validity by testing 12 a priori hypotheses on the correlation of CPAT domain scores with global impression and Assessment of Inter-professional Team Collaboration Scale (AITCS). We assessed internal consistency using Cronbach's alpha and assessed test-retest reliability using intraclass correlation coefficient (ICC) between responses at 2 time points (baseline and 2 weeks). From the responses of the 148 participants, we established construct validity by meeting >75% of the hypotheses formulated a priori. We showed high internal consistency in 7 domains (Cronbach's alpha >0.7) of the CPAT, and moderate internal consistency in one domain (Cronbach's alpha = 0.63) of the CPAT. We also demonstrated acceptable test-retest reliability in seven domains of the CPAT (ICC >0.5). This study provides support for the content validity, construct validity, internal consistency and test–retest reliability of the CPAT to measure the degree of inter-professional collaboration in a community hospital in Singapore. This enables clinicians and researchers to use the CPAT to measure the interventions to enhance inter-professional collaboration in Singapore.

Measurement properties and interpretability of the PROMIS item banks in stroke patients: a systematic review.

Both the International Consortium for Health Outcomes Measurement and the National Institutes of Health recommend the use of Patient-Reported Outcomes Measurement Information System (PROMIS®) measures in clinical care and research for stroke patients. This study aimed to systematically review the literature on the measurement properties and interpretability of PROMIS measures in stroke patients. Nine databases were searched from January 1st, 2007 till April 12th, 2021 for studies concerning the measurement properties and interpretability of PROMIS measures in stroke patients. The findings of these studies were analyzed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews of Patient-Reported Outcome Measures (PROMs). Ten studies were included. The PROMIS Global Health was studied the most: its two subscales had sufficient structural validity in one study of very good quality, sufficient construct validity with > 75% of hypotheses tested confirmed (high GRADE rating), sufficient internal consistency, i.e. α ≥ 0.70 in two studies (high GRADE rating), sufficient reliability, i.e. ICC ≥ 0.70 in one study of doubtful quality, and indeterminate responsiveness in one study of inadequate quality. For other PROMIS measures, the measurement properties and interpretability were limitedly studied. The PROMIS Global Health showed sufficient structural and construct validity and internal consistency in stroke patients. There is a need for further research on content validity, structural validity, and measurement invariance of PROMIS measures in stroke patients. Trial Registration Information: CRD42020203044 (PROSPERO).
