COSMIN systematic review and meta-analysis of the measurement properties of the PANSS-6.

The Positive and Negative Syndrome Scale (PANSS) is widely used to assess schizophrenia symptoms. Initially designed with three subscales, Marder et al.´s 5-factor-Model (M5M) first proposed in 1997 has been frequently used in treatment trials, but it has never been systematically reviewed for its measurement properties. We utilized the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews and meta-analytical procedures to assess the psychometric properties of the M5M-PANSS. COSMIN comprises several steps: literature search, risk-of-bias assessments, assessing the updated criteria for good measurement properties, feasibility aspects and grading the quality of the evidence. We further assessed the goodness of fit of other PANSS factor models. We included 95 publications. The M5M-PANSS showed good construct validity, but “insufficient” structural validity. Evidence of other COSMIN domains is largely lacking. Among the multiple (73) factor solutions examined with confirmatory methods, several other 5-factor solutions had better model fit. According to COSMIN rules the M5M should not be recommended for use. Other five-factor models such as the one proposed by Wallwork et al.1 warrant further evaluation. Nevertheless, the factor composition of the M5M and these other models was relatively similar, so previously published results should not be disregarded.

Recognizing and appropriately responding to ethical considerations is a crucial element of ethical nursing practice. To mitigate instances of ethical incongruity in healthcare and to promote nurses' comprehension of their professional ethical responsibilities, it is imperative for researchers to accurately evaluate ethical sensitivity. Conducting a systematic review of the available instruments would enable practitioners to determine the most suitable instrument for implementation in the field of nursing. This review aims to systematically assess the measurement properties of instruments used to measure ethical sensitivity in nursing. A systematic literature search was conducted in July 2022 in the following electronic databases: Scopus, CINAHL, APAPsycINFO, Embase, Web of Science, and PubMed. Two reviewers independently screened and assessed the studies in accordance with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. The updated criteria for good measurement properties are used to rate the result of measurement properties, and the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to grade the quality of the summarized evidence. This review encompasses a total of 29 studies that describe 11 different instruments. Neither cross-cultural validity nor responsiveness was examined in any of the included studies. Whereas the majority of the instruments were conducted with at least some type of validity assessment, nearly all of the reliability results rated were indeterminate. Two instruments were recommended, the Ethical Sensitivity Questionnaire for Nursing Students (ESQ-NS) and the Ethical Awareness Scale for nurses in intensive care units. It is recommended that new self-administration instruments for special nursing settings be developed in accordance with the item response theory (IRT)/Rasch model. The selection of ethical sensitivity measurement instruments in nursing, and further research on the development, psychometric, and cross-cultural adaptation of these instruments, could be conducted in accordance with the findings and suggestions of this systematic review. • This review was conducted to assess 11 instruments that were used to measure ethical sensitivity in nursing in 29 studies. • The Ethical Sensitivity Questionnaire for Nursing Students (ESQ-NS) and the Ethical Awareness Scale for nurses in intensive care units can be recommended, but further reliability and cross-cultural validity testing are needed. • The IRT/Rasch model is also recommended to measure ethical sensitivity in nursing. • The potential limitation of utilizing the COSMIN checklist for assessing methodological quality is worth considering. • Test-retest was considered inappropriate; thus, the reliability testing of ethical sensitivity measurement instruments still needs to be explored.

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.

Characteristics of chronic obstructive pulmonary disease (COPD) can include shortness of breath, chronic cough, sputum production and reduced exercise capacity. The sit-to-stand (STS) test variations (e.g., 5-repetition STS, 30-second STS) may be appropriate outcome measures to assess exercise capacity in people with COPD. To date, the measurement properties of the various STS tests in people with COPD have not been synthesized in a systematic review since the publication of the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines. The purpose of this proposed systematic review is to synthesize the literature of the measurement properties of the STS test variations among people with COPD. The review will be conducted with methods consistent with the COSMIN guidelines. Peer-reviewed publications will be included if they assessed the measurement properties (reliability, validity, responsiveness) of a STS test in community-dwelling adults with COPD. We will search six databases from inception. Study selection and data extraction will be conducted independently and in duplicate. We will assess the risk of bias using the COSMIN Risk of Bias tool, assess results against the COSMIN updated criteria for good measurement properties, and summarize certainty of evidence using the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. Study results will be pooled by calculating weighted means and 95% confidence intervals or summarized narratively, as appropriate. This will be the first systematic review to synthesize the measurement properties of the STS tests in people with COPD using the methods recommended by COSMIN. Consequently, its results will be robust and may help clinicians or researchers identify the best variation of the STS test to use in their practice.

The 41-item Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) is a widely used and freely available patient-reported outcome measure (PROM). However, data on its reliability, validity, and responsiveness remain unclear. Therefore, this study aimed to systematically review the measurement properties of the QUALEFFO-41. A systematic search of MEDLINE, EBSCOhost, and Cochrane Library from their inception up to December 2022 was performed. Data were extracted, and the methodological quality of each measurement property was evaluated according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. The evidence of the measurement properties was rated against the updated criteria for good measurement properties, and the quality of evidence was graded using the modified GRADE approach. A total of 99 articles were identified, of which eight studies were included in the review. The QUALEFFO-41 is categorized as B as it demonstrated moderate quality evidence for sufficient content validity, moderate-to-high quality evidence for sufficient hypothesis testing for construct validity (except for the social function domain for convergent validity), and very low-quality evidence for sufficient responsiveness. For structural validity and internal consistency, only the domains of pain and general health perception were sufficient with low-quality evidence. For reliability, only the domain of physical function was sufficient with low-quality evidence. None of the studies reported measurement error, cross-cultural validity, and criterion validity. The QUALEFFO-41 may be a promising, valid, and reliable PROM to assess HRQoL in osteoporosis patients with vertebral fractures. However, future studies must focus on good methodological quality to strengthen the evidence of measurement properties, especially on structural validity, reliability, responsiveness, and cross-cultural validity. The systematic review evaluated the measurement properties of the QUALEFFO-41 questionnaire for assessing Health-Related Quality of Life (HRQoL) in osteoporosis patients. The review found moderate-to-high-quality evidence for construct validity but limited evidence for responsiveness and other properties. Future studies should focus on strengthening the evidence, particularly for structural validity, reliability, responsiveness, and cross-cultural validity. The QUALEFFO-41 shows promise as a valid and reliable PROM for HRQoL assessment in osteoporosis patients.

The Positive and Negative Syndrome Scale (PANSS) is the most widely used tool for assessing the symptoms of schizophrenia. Despite its widespread use, the psychometric properties of the PANSS have not been systematically reviewed. This study fills that gap in the scientific literature. We utilized the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews and meta-analytical procedures to assess the psychometric properties of the PANSS in its original three-subscale form as well as the quality level of the evidence available. On this basis we formulated recommendations for future research and use. A study protocol was registered under 10.17605/OSF.IO/5EGMD. The search period was until February 21,2024. We included 119 publications. According to COSMIN, the PANSS demonstrated sufficient reliability, construct validity, and responsiveness; but had significant shortcomings in content validity and structural validity. The original three-factor model showed poor structural validity, leading to its COSMIN classification as "not recommendable". The subscales showed overall acceptable measurement properties. However, the lack of structural validity of the three-subscale model renders its subscales less useful. Moreover, the PANSS negative subscale does not cover all domains of the National Institute of Mental Health consensus. Due to the length of the instrument (30-50min), it is barely useable in clinical practice. Although the PANSS is the standard scale for schizophrenia symptom severity, its shortcomings regarding fundamental psychometric domains and practical applicability warrant the development of new scales for which appropriate methods should be applied from the start. There was no specific funding source for this research.

ObjectivesPatient-reported outcome measures (PROMs) are often used to evaluate the outcome of treatment in patients with distal radial fractures. Which PROM to select is often based on assessment of measurement properties, such as validity and reliability. Measurement properties are assessed in clinimetric studies, and results are often reviewed without considering the methodological quality of these studies. Our aim was to systematically review the methodological quality of clinimetric studies that evaluated measurement properties of PROMs used in patients with distal radial fractures, and to make recommendations for the selection of PROMs based on the level of evidence of each individual measurement property.MethodsA systematic literature search was performed in PubMed, EMbase, CINAHL and PsycINFO databases to identify relevant clinimetric studies. Two reviewers independently assessed the methodological quality of the studies on measurement properties, using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Level of evidence (strong / moderate / limited / lacking) for each measurement property per PROM was determined by combining the methodological quality and the results of the different clinimetric studies.ResultsIn all, 19 out of 1508 identified unique studies were included, in which 12 PROMs were rated. The Patient-rated wrist evaluation (PRWE) and the Disabilities of Arm, Shoulder and Hand questionnaire (DASH) were evaluated on most measurement properties. The evidence for the PRWE is moderate that its reliability, validity (content and hypothesis testing), and responsiveness are good. The evidence is limited that its internal consistency and cross-cultural validity are good, and its measurement error is acceptable. There is no evidence for its structural and criterion validity. The evidence for the DASH is moderate that its responsiveness is good. The evidence is limited that its reliability and the validity on hypothesis testing are good. There is no evidence for the other measurement properties.ConclusionAccording to this systematic review, there is, at best, moderate evidence that the responsiveness of the PRWE and DASH are good, as are the reliability and validity of the PRWE. We recommend these PROMs in clinical studies in patients with distal radial fractures; however, more clinimetric studies of higher methodological quality are needed to adequately determine the other measurement properties.Cite this article: Dr Y.

To systematically assess the validity of patient-reported outcome measures (PROMs) for patients undergoing inguinal hernia repair. A systematic review was performed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews of PROMs. PubMed, EMBASE and PsycINFO were consulted. Only studies explicitly aimed at validation of PROMs specific for patients with inguinal hernia were included. Data regarding measurement properties of PROMs were extracted from the included studies. Each study was critically assessed for methodological quality and each PROM was evaluated for sufficient measurement properties. We included 15 studies, covering 11 different PROMs. The Carolinas Comfort Scale was the most frequently investigated PROM, being covered in five of the included publications. The included PROMs were evaluated according to nine different measurement properties, of which internal consistency and construct validity were the most frequently assessed. Evidence regarding content validity and structural validity was universally inadequate, according to the criteria for good measurement properties, as defined by the COSMIN. Based on the current evidence, it is not possible to formulate recommendations for application of PROMs for patients undergoing inguinal hernia repair. Further validation of the included PROMs is necessary especially regarding content validity and structural validity.

Patient-reported outcome measures (PROMs) are recommended to measure the impact of a health condition or intervention effectiveness as they aim to capture what is most meaningful to patients. Several PROMs are used to evaluate pelvic organ prolapse (POP)-related domains, yet the measurement properties of these instruments have not been fully explored with a rigorous analysis of the methodological quality and quality of evidence. To conduct a systematic review reporting on the measurement properties of PROMs used for the assessment of POP-related domains in accordance with the COSMIN guidelines. Five databases were searched from inception to December 2023. Studies were eligible if they involved (1) at least one group of female adults diagnosed with or presenting with symptoms of POP; (2) a self-reported outcome measure (PROMs, questionnaires) to evaluate POP-related domains; and (3) at least one measurement property. Methodological quality and measurement quality were assessed using the COSMIN risk of bias (ROB) checklist and the COSMIN criteria for good measurement properties. A total of 13 PROMs were included. The BIPOP had the lowest ROB for Content Validity. The POP-SS was the only PROM with sufficient evidence of adequate construct validity and responsiveness to be used in both surgical and conservative management settings. This original work identified a gap in evidence regarding the measurement qualities of identified PROMs used in the POP population.

Preserving and enhancing mobility is an important part of healthy ageing. Life-space mobility is a construct that captures actual mobility within the home and the community. The objective of this systematic review was to synthesise the measurement properties and interpretability of scores produced by life-space mobility measures in community-dwelling older adults. This systematic review followed Consensus-based Standards for the selection of health Measurement Instruments (COSMIN). Multiple databases were searched to identify potentially relevant articles. Data extraction and assessment of methodological quality was conducted by two independent reviewers. When possible, results were quantitatively pooled for each measurement property. If studies could not be combined quantitatively, then findings were summarised qualitatively using means and percentage of confirmed hypothesis. Synthesised results were assessed against the COSMIN criteria for good measurement properties. A total of 21 full text articles were included in the review. The University of Alabama at Birmingham Study of Aging Life-Space Assessment (LSA) was the most evaluated life-space mobility measure. The LSA demonstrated content validity, internal consistency (Cronbach's alpha 0.80-0.92), reliability [intra-class correlation value 0.89 (95% confidence interval (CI): 0.80, 0.94)] and convergent validity with measures of physical function in community-dwelling older adults. This systematic review summarised the measurement properties of life-space mobility measures in community-dwelling older adults following COSMIN guidelines. The LSA has been translated into multiple languages and has sufficient measurement properties for assessing life-space mobility among community-dwelling older adults.

PurposeTo conduct a systematic review of the quality of generic patient-reported outcome measures (PROMs) for clinical or population research or practice using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology, and to derive recommendations for usage of generic PROMs within Switzerland.MethodsWe searched six databases (PubMed, CINAHL, Web of Science, PsycINFO, EMBASE, Cochrane) and grey literature in Switzerland to identify studies reporting on the development or validation of any generic PROMs used in Switzerland. Methodological quality of each study was assessed with COSMIN’s Risk of Bias Checklist. Measurement property evidence (content validity and psychometrics) was further evaluated according to COSMIN’s criteria for good measurement properties. Overall evidence was synthesized according to COSMIN’s modified GRADE approach to generate recommendations for future use or disuse of generic PROMs within Switzerland.ResultsData from k = 49 studies reporting on five PROMs (EQ-5D, SF-36, PROMIS-29, WHOQOL-BREF, WORQ) were included. Among these, the SF-36 can be recommended for use. The PROMIS-29, WHOQOL-BREF, and WORQ have the potential to be recommended for use, but require further validation. The EQ-5D is not recommendable for future use.ConclusionWith a limited number of content validity studies, WHOQOL-BREF showed sufficiency with moderate quality, while other PROMs showed mixed quality ranging from very low to moderate. Synthesizing all measurement property evidence, SF-36 was identified as recommendable. PROMIS-29, WHOQOL-BREF, and WORQ were identified as potentially recommendable pending further validation evidence. The EQ-5D was identified as unrecommendable for future use within Switzerland.

Personal Growth Initiative (PGI), a cognitive and behavioural skill set for intentional growth, is often measured using the multidimensional Personal Growth Initiative Scale-II (PGIS-II). This systematic review examined its structural validity, reliability, measurement invariance, and construct validity. A literature search across multiple databases identified 15 studies evaluating the psychometric properties of the PGIS-II. Study quality was assessed with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist (version 3.0). The specified psychometric properties were evaluated based on COSMIN criteria for good measurement properties, and a modified Grading, Recommendations, Assessment, Development, and Evaluation (GRADE) approach assessed the certainty of evidence. Findings showed structural validity and internal consistency variability, with some modifications to the first-order four-factor model lacking theoretical justification. A second-order four-factor structure and a bifactor model demonstrated moderate to high-quality evidence. Test–retest reliability was confirmed only for the Chinese (moderate quality) and Turkish (low quality) versions. Measurement invariance was supported for the English and Portuguese first-order four-factor models, as well as the English bifactor model. Construct validity was examined for seven versions, yielding mixed results. While some versions may be suitable for specific contexts, inconsistencies in psychometric evidence emphasise the need to further clarify the instrument's structure and psychometric performance in diverse populations through high-quality studies. Nevertheless, based on our findings, the bifactor model appears to be the most suitable structure for the PGIS-II, as it captures both the general PGI construct and its subdimensions, at least for now.
