ABSTRACT: Background
Technological development and improvements in Wearable Physiological Monitoring devices, have facilitated the wireless and continuous field-based monitoring/capturing of physiologic measures in healthy, clinical or athletic populations. These devices have many applications for prevention and rehabilitation of musculoskeletal disorders, assuming reliable and valid data is collected. The purpose of this study was to appraise the quality and synthesize findings from published studies on psychometric properties of heart rate measurements taken with the Zephyr Bioharness device.Methods
We searched the Embase, Medline, PsycInfo, PuMed and Google Scholar databases to identify articles. Articles were appraised for quality using a structured clinical measurement specific appraisal tool. Two raters evaluated the quality and conducted data extraction. We extracted data on the reliability (intra-class correlation coefficients and standard error of measurement) and validity measures (Pearson/Spearman's correlation coefficients) along with mean differences. Agreement parameters were summarised by the average biases and 95% limits of agreement.Results
A total of ten studies were included: quality ratings ranged from 54 to 92%. The intra-class correlation coefficients reported ranged from 0.85-0.98. The construct validity coefficients compared against gold standard calibrations or other commercially used devices, ranged from 0.74-0.99 and 0.67-0.98 respectively. Zephyr Bioharness agreement error ranged from -?4.81 (under-estimation) to 3.00 (over-estimation) beats per minute, with varying 95% limits of agreement, when compared with gold standard measures.Conclusion
Good to excellent quality evidence from ten studies suggested that the Zephyr Bioharness device can provide reliable and valid measurements of heart rate across multiple contexts, and that it displayed good agreements vs. gold standard comparators - supporting criterion validity.

Project description:AimsOccupational Burnout (OB) is currently measured through several Patient-Reported Outcome Measures (PROMs) and some of them have become widely used in occupational health research and practice. We, therefore, aimed to review and grade the psychometric validity of the five OB PROMs considered as valid for OB measure in mental health professionals (the Maslach Burnout Inventory (MBI), the Pines' Burnout Measure (BM), the Psychologist Burnout Inventory (PBI), the OLdenburg Burnout Inventory (OLBI) and the Copenhagen Burnout Inventory (CBI)).MethodsWe conducted systematic literature searches in MEDLINE, PsycINFO and EMBASE databases. We reviewed studies published between January 1980 and September 2018 following a methodological framework, in which each step of PROM validation, the reference method, analytical technics and result interpretation criteria were assessed. Using the COnsensus-based Standards for the selection of health Measurement Instruments we evaluated the risk of bias in studies assessing content and criterion validity, structural validity, internal consistency, reliability, measurement error, hypotheses testing and responsiveness of each PROM. Finally, we assessed the level of evidence for the validity of each PROM using the GRADE approach.ResultsWe identified 6541 studies, 19 of which were included for review. Fifteen studies dealt with MBI whereas BM, PBI, OLBI and CBI were each examined in only one study. OLBI had the most complete validation, followed by CBI, MBI, BM and PBI, respectively. When examining the result interpretation correctness, the strongest disagreement was observed for MBI (27% of results), BM (25%) and CBI (17%). There was no disagreement regarding PBI and OLBI. For OLBI and CBI, the quality of evidence for sufficient content validity, the crucial psychometric property, was moderate; for MBI, BM and PBI, it was very low.ConclusionTo be validly and reliably used in medical research and practice, PROM should exhibit robust psychometric properties. Among the five PROMs reviewed, CBI and, to a lesser extent, OLBI meet this prerequisite. The cross-cultural validity of these PROMs was beyond the scope of our work and should be addressed in the future. Moreover, the development of a diagnostic standard for OB would be helpful to assess the sensitivity and specificity of the PROMs and further reexamine their validity.The study protocol was registered in PROSPERO (CRD 42019124621).

Project description:BackgroundSuboptimal health status (SHS) measurement has now been recognized as an essential construct in predictive, preventive, and personalized medicine. Currently, there are limited tools, and an ongoing debate about appropriate tools. Therefore, it is crucial to evaluate and generate conclusive evidence about the psychometric properties of available SHS tools.ObjectiveThis research aimed to identify and critically assess the psychometric properties of available SHS instruments and provide recommendations for their future use.MethodsArticles were retrieved by following the guidelines of the PRISMA checklist, and the robustness of methods and evidence about the measurement properties was assessed using the adapted COSMIN checklist. The review was registered in PROSPERO.ResultsThe systematic review identified 14 publications describing four subjective SHS measures with established psychometric properties; these included the Suboptimal Health Status Questionnaire-25 (SHSQ-25), Sub-health Measurement Scale Version 1.0 (SHMS V1.0), Multidimensional Sub-health Questionnaire of Adolescents (MSQA), and the Sub-Health Self-Rating Scale (SSS). Most studies were conducted in China and reported three reliability indices: (1) the internal consistency measured by Cronbach's α value ranged between 0.70 and 0.96; (2) the test-retest reliability; and (3) the split-half reliability coefficient values ranged between 0.64 and 0.98, and between 0.83 and 0.96, respectively. For the values of validity coefficients in the case of SHSQ-25 > 0.71, the SHMS-1.0 ranged from 0.64 to 0.87, and the SSS ranged from 0.74 to 0.96. Using these existing and well-characterized tools rather than constructing original tools is beneficial, given that the existing choice demonstrated sound psychometric properties and established norms.ConclusionsThe SHSQ-25 stood out as being more suitable for the general population and routine health surveys, because it is short and easy to complete. Therefore, there is a need to adapt this tool by translating it into other languages, including Arabic, and establishing norms based on populations from other regions of the world.

Project description:BackgroundThe management of people living with HIV and AIDS is multidimensional and complex. Using patient-reported outcome measures (PROMs) has been increasingly recognized to be the key factor for providing patient-centered health care to meet the lifelong needs of people living with HIV and AIDS from diagnosis to death. However, there is currently no consensus on a PROM recommended for health care providers and researchers to assess health outcomes in people living with HIV and AIDS.ObjectiveThe purpose of this systematic review was to summarize and categorize the available validated HIV-specific PROMs in adults living with HIV and AIDS and to assess these PROMs using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology.MethodsThis systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search of 3 recommended databases (PubMed, Embase, and PsychINFO) was conducted on January 15, 2021. Studies were included if they assessed any psychometric property of HIV-specific PROMs in adults living with HIV and AIDS and met the eligibility criteria. The PROMs were assessed for 9 psychometric properties, evaluated in each included study following the COSMIN methodology by assessing the following: the methodological quality assessed using the COSMIN risk of bias checklist; overall rating of results; level of evidence assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluation approach; and level of recommendation.ResultsA total of 88 PROMs classified into 8 categories, assessing the psychometric properties of PROMs for adults living with HIV and AIDS, were identified in 152 studies including 79,213 people living with HIV and AIDS. The psychometric properties of most included PROMs were rated with insufficient evidence. The PROMs that received class A recommendation were the Poz Quality of Life, HIV Symptom Index or Symptoms Distress Module of the Adult AIDS Clinical Trial Group, and People Living with HIV Resilience Scale. In addition, because of a lack of evidence, recommendations regarding use could not be made for most of the remaining assessed PROMs (received class B recommendation).ConclusionsThis systematic review recommends 3 PROMs to assess health outcomes in adults living with HIV and AIDS. However, all these PROMs have some shortcomings. In addition, most of the included PROMs do not have sufficient evidence for assessing their psychometric properties and require a more comprehensive validation of the psychometric properties in the future to provide more scientific evidence. Thus, our findings may provide a reference for the selection of high-quality HIV-specific PROMs by health care providers and researchers for clinical practice and research.

Project description:Addressing HIV-related stigma requires the use of psychometrically sound measures. However, despite the Berger HIV stigma scale (HSS) being among the most widely used measures for assessing HIV-related stigma, no study has systematically summarised its psychometric properties. This review investigated the psychometric properties of the HSS. A systematic review of articles published between 2001 and August 2021 was undertaken (CRD42020220305) following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Additionally, we searched the grey literature and screened the reference lists of the included studies. Of the total 1241 studies that were screened, 166 were included in the review, of which 24 were development and/or validation studies. The rest were observational or experimental studies. All the studies except two reported some aspect of the scale's reliability. The reported internal consistency ranged from acceptable to excellent (Cronbach's alpha ≥ 0.70) in 93.2% of the studies. Only eight studies reported test-retest reliability, and the reported reliability was adequate, except for one study. Only 36 studies assessed and established the HSS's validity. The HSS appears to be a reliable and valid measure of HIV-related stigma. However, the validity evidence came from only 36 studies, most of which were conducted in North America and Europe. Consequently, more validation work is necessary for more precise insights.

Project description:BackgroundThe important role of leaders in the translation of health research is acknowledged in the implementation science literature. However, the accurate measurement of leadership traits and behaviours in health professionals has not been directly addressed. This review aimed to identify whether scales which measure leadership traits and behaviours have been found to be reliable and valid for use with health professionals.MethodsA systematic review was conducted. MEDLINE, EMBASE, PsycINFO, Cochrane, CINAHL, Scopus, ABI/INFORMIT and Business Source Ultimate were searched to identify publications which reported original research testing the reliability, validity or acceptability of a leadership-related scale with health professionals.ResultsOf 2814 records, a total of 39 studies met the inclusion criteria, from which 33 scales were identified as having undergone some form of psychometric testing with health professionals. The most commonly used was the Implementation Leadership Scale (n = 5) and the Multifactor Leadership Questionnaire (n = 3). Of the 33 scales, the majority of scales were validated in English speaking countries including the USA (n = 15) and Canada (n = 4), but also with some translations and use in Europe and Asia, predominantly with samples of nurses (n = 27) or allied health professionals (n = 10). Only two validation studies included physicians. Content validity and internal consistency were evident for most scales (n = 30 and 29, respectively). Only 20 of the 33 scales were found to satisfy the acceptable thresholds for good construct validity. Very limited testing occurred in relation to test-re-test reliability, responsiveness, acceptability, cross-cultural revalidation, convergent validity, discriminant validity and criterion validity.ConclusionsSeven scales may be sufficiently sound to be used with professionals, primarily with nurses. There is an absence of validation of leadership scales with regard to physicians. Given that physicians, along with nurses and allied health professionals have a leadership role in driving the implementation of evidence-based healthcare, this constitutes a clear gap in the psychometric testing of leadership scales for use in healthcare implementation research and practice.Trial registrationThis review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) (see Additional File 1) (PLoS Medicine. 6:e1000097, 2009) and the associated protocol has been registered with the PROSPERO International Prospective Register of Systematic Reviews (Registration Number CRD42019121544 ).

Project description:BACKGROUND:Early identification of children with motor difficulties, such as developmental coordination disorder (DCD), is essential. At present only a fraction of children with DCD are identified. The purpose of the study was to systematically review the literature from 1994 to 2017 on observational screening tools and to evaluate the validity, reliability and usability of the questionnaires used. METHODS:The review of the literature was conducted to synthesize the data from five electronic databases for children aged 6-12?years. The following databases were searched: Academic search Elite (EBSCO), ERIC (ProQuest), MEDLINE (Ovid), PsycINFO (ProQuest), and SPORTDiscus with Full Text (EBSCO). The studies meeting our inclusion criteria were analyzed to assess the psychometric properties and feasibility of the measures. RESULTS:The literature search retrieved 1907 potentially relevant publications. The final number of studies that met the inclusion criteria of our systematic review was 45. There were 11 questionnaires for parents, teachers and children. None of the questionnaires was valid for population-based screening as the only measurement tool. CONCLUSIONS:There are many challenges in using initial screening tools to identify children with motor difficulties. Nevertheless, many promising questionnaires are being developed that can provide information on functional skills and limitations across a variety of tasks and settings in the daily lives of children with DCD. The review provides much needed information about the current scales used in many clinical, educational and research settings. Implications for assessing psychometric properties of the developed questionnaires and further research are discussed. TRIAL REGISTRATION:PROSPERO, CRD42018087532 .

Project description:ObjectiveGross motor assessment tools have a critical role in identifying, diagnosing and evaluating motor difficulties in childhood. The objective of this review was to systematically evaluate the psychometric properties and clinical utility of gross motor assessment tools for children aged 2-12 years.MethodA systematic search of MEDLINE, Embase, CINAHL and AMED was performed between May and July 2017. Methodological quality was assessed with the COnsensus-based Standards for the selection of health status Measurement INstruments checklist and an outcome measures rating form was used to evaluate reliability, validity and clinical utility of assessment tools.ResultsSeven assessment tools from 37 studies/manuals met the inclusion criteria: Bayley Scale of Infant and Toddler Development-III (Bayley-III), Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2), Movement Assessment Battery for Children-2 (MABC-2), McCarron Assessment of Neuromuscular Development (MAND), Neurological Sensory Motor Developmental Assessment (NSMDA), Peabody Developmental Motor Scales-2 (PDMS-2) and Test of Gross Motor Development-2 (TGMD-2). Methodological quality varied from poor to excellent. Validity and internal consistency varied from fair to excellent (?=0.5-0.99). The Bayley-III, NSMDA and MABC-2 have evidence of predictive validity. Test-retest reliability is excellent in the BOT-2 (intraclass correlation coefficient (ICC)=0.80-0.99), PDMS-2 (ICC=0.97), MABC-2 (ICC=0.83-0.96) and TGMD-2 (ICC=0.81-0.92). TGMD-2 has the highest inter-rater (ICC=0.88-0.93) and intrarater reliability (ICC=0.92-0.99).ConclusionsThe majority of gross motor assessments for children have good-excellent validity. Test-retest reliability is highest in the BOT-2, MABC-2, PDMS-2 and TGMD-2. The Bayley-III has the best predictive validity at 2 years of age for later motor outcome. None of the assessment tools demonstrate good evaluative validity. Further research on evaluative gross motor assessment tools are urgently needed.

Project description:BackgroundSignificant resources are being invested into eHealth technology to improve health care. Few resources have focused on evaluating the impact of use on patient outcomes A standardized set of metrics used across health systems and research will enable aggregation of data to inform improved implementation, clinical practice, and ultimately health outcomes associated with use of patient-facing eHealth technologies.ObjectiveThe objective of this project was to conduct a systematic review to (1) identify existing instruments for eHealth research and implementation evaluation from the patient's point of view, (2) characterize measurement components, and (3) assess psychometrics.MethodsConcepts from existing models and published studies of technology use and adoption were identified and used to inform a search strategy. Search terms were broadly categorized as platforms (eg, email), measurement (eg, survey), function/information use (eg, self-management), health care occupations (eg, nurse), and eHealth/telemedicine (eg, mHealth). A computerized database search was conducted through June 2014. Included articles (1) described development of an instrument, or (2) used an instrument that could be traced back to its original publication, or (3) modified an instrument, and (4) with full text in English language, and (5) focused on the patient perspective on technology, including patient preferences and satisfaction, engagement with technology, usability, competency and fluency with technology, computer literacy, and trust in and acceptance of technology. The review was limited to instruments that reported at least one psychometric property. Excluded were investigator-developed measures, disease-specific assessments delivered via technology or telephone (eg, a cancer-coping measure delivered via computer survey), and measures focused primarily on clinician use (eg, the electronic health record).ResultsThe search strategy yielded 47,320 articles. Following elimination of duplicates and non-English language publications (n=14,550) and books (n=27), another 31,647 articles were excluded through review of titles. Following a review of the abstracts of the remaining 1096 articles, 68 were retained for full-text review. Of these, 16 described an instrument and six used an instrument; one instrument was drawn from the GEM database, resulting in 23 articles for inclusion. None included a complete psychometric evaluation. The most frequently assessed property was internal consistency (21/23, 91%). Testing for aspects of validity ranged from 48% (11/23) to 78% (18/23). Approximately half (13/23, 57%) reported how to score the instrument. Only six (26%) assessed the readability of the instrument for end users, although all the measures rely on self-report.ConclusionsAlthough most measures identified in this review were published after the year 2000, rapidly changing technology makes instrument development challenging. Platform-agnostic measures need to be developed that focus on concepts important for use of any type of eHealth innovation. At present, there are important gaps in the availability of psychometrically sound measures to evaluate eHealth technologies.

Project description:BackgroundSexual desire is one of the domains of sexual function with multiple dimensions, which commonly affects men and women around the world. Classically, its assessment has been applied through self-report tools; however, an issue is related to the evidence level of these questionnaires and their validity. Therefore, a systematic review addressing the available questionnaires is really relevant, since it will be able to show their psychometric properties and evidence levels.MethodA systematic review was carried out in the PubMed, EMBASE, PsycINFO, Science Direct, and Web of Science databases. The search strategy was developed according to the following research question and combination of descriptors and keywords, including original studies with no limit of publication date and in Portuguese, English, and Spanish. Two reviewers carried out the selection of articles by abstracts and full texts as well as the analysis of the studies independently. The methodological quality of the instruments was evaluated by the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist.ResultsThe search resulted in 1203 articles, of which 15 were included in the review. It identified 10 instruments originally developed in the English language. Unsatisfactory results on methodological quality were evidenced in cultural adaptation studies with no description of the steps of the processes and inadequacy of techniques and parameters of adequacy for models. The Principal Component Analysis with Varimax rotation predominated in the studies.ConclusionsThe limitation of the techniques applied in the validation process of the reviewed instruments was evident. A limitation was observed in the number of adaptations conducted and contexts to which the instruments were applied, making it impossible to reach a better understanding of the functioning of instruments. In future studies, the use of robust techniques can ensure the quality of the psychometric properties and the accuracy and stability of instruments. A detailed description of procedures and results in validation studies may facilitate the selection and use of instruments in the academic and/or clinical settings.Systematic review registrationPROSPERO CRD42018085706.

Project description:IntroductionImproving social inclusion opportunities for population health has been identified as a priority area for international policy. There is a need to comprehensively examine and evaluate the quality of psychometric properties of measures of social inclusion that are used to guide social policy and outcomes.ObjectiveTo conduct a systematic review of the literature on all current measures of social inclusion for any population group, to evaluate the quality of the psychometric properties of identified measures, and to evaluate if they capture the construct of social inclusion.MethodsA systematic search was performed using five electronic databases: CINAHL, PsycINFO, Embase, ERIC and Pubmed and grey literature were sourced to identify measures of social inclusion. The psychometric properties of the social inclusion measures were evaluated against the COSMIN taxonomy of measurement properties using pre-set psychometric criteria.ResultsOf the 109 measures identified, twenty-five measures, involving twenty-five studies and one manual met the inclusion criteria. The overall quality of the reviewed measures was variable, with the Social and Community Opportunities Profile-Short, Social Connectedness Scale and the Social Inclusion Scale demonstrating the strongest evidence for sound psychometric quality. The most common domain included in the measures was connectedness (21), followed by participation (19); the domain of citizenship was covered by the least number of measures (10). No single instrument measured all aspects within the three domains of social inclusion. Of the measures with sound psychometric evidence, the Social and Community Opportunities Profile-Short captured the construct of social inclusion best.ConclusionsThe overall quality of the psychometric properties demonstrate that the current suite of available instruments for the measurement of social inclusion are promising but need further refinement. There is a need for a universal working definition of social inclusion as an overarching construct for ongoing research in the area of the psychometric properties of social inclusion instruments.
