Quality of measurement properties of medication adherence instruments in cardiovascular diseases and type 2 diabetes mellitus: a systematic review and meta-analysis.

BACKGROUND: Medication adherence has a major impact on reducing mortality and healthcare costs related to the treatment of cardiovascular diseases and diabetes mellitus. Selecting the best patient-reported outcome measure (PROM) among the many available for this kind of patient is extremely important. This study aims to critically assess, compare and synthesize the quality of the measurement properties of patient-reported outcome measures to assess medication adherence among patients with cardiovascular diseases and/or type 2 diabetes mellitus. METHODS: This review followed the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The searches were performed in Web of Science, SCOPUS, PubMed, CINAHL, EMBASE, LILACS, PsycINFO, and ProQuest (gray literature). RESULTS: A total of 110 records encompassing 27 different PROMs were included in the review. The included records were published between 1986 and 2023, most of which reported studies conducted in the United States and were published in English. None of the PROMs were classified in the category "a", thus being recommended for use due to the quality of its measurement properties. The PROMs that should not be recommended for use (category "c") are the MTA, GMAS, DMAS-7, MALMAS, ARMS-D, and 5-item questionnaire. The remaining PROMs, e.g., MMAS-8, SMAQ, MEDS, MNPS, ARMS-12, MGT, MTA-OA, MTA-Insulin, LMAS-14, MARS-5, A-14, ARMS-10, IADMAS, MAQ, MMAS-5, ProMAS, ARMS-7, 3-item questionnaire, AS, 12-item questionnaire, and Mascard were considered as having the potential to be recommended for use (category "b"). CONCLUSION: None of the included PROMs met the criteria for being classified as trusted and recommended for use for patients with cardiovascular diseases and/or type 2 diabetes mellitus. However, 21 PROMs have the potential to be recommended for use, but further studies are needed to ensure their quality based on the COSMIN guideline for systematic reviews of PROMs. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019129109.

Content Validity of a Questionnaire Based on the Theory of Planned Behavior to Assess the Psychosocial Determinants of Insulin Adherence.

OBJECTIVES: To verify the content validity of questions of an insulin adherence questionnaire based on the Theory Planned Behavior in outpatients with type 2 diabetes mellitus. METHODS: The instrument was derived from a tool created to evaluate psychosocial determinants of adherence to oral antidiabetics medications in the Brazilian context, and was submitted for evaluation by a committee of experts and members of the target population. The item-level content validity index, the scale-level content validity index averaging calculation method, and the modified kappa coefficient were used to evaluate agreement among specialists. The comprehensibility of the instrument by members of the target population was qualitatively analyzed. RESULTS: The item-level content validity index was found to be lower than desired in 6 of the 20 items analyzed. Of these, one item was modified and 5 were excluded after the comprehensibility evaluation by members of the target population; one item from the perceived control scale was excluded. Content validation resulted in an instrument with 14 items, distributed in the domains intention (4 items), attitude (3 items), perceived norm (4 items), and perceived control (4 items) scales. CONCLUSIONS: The findings support good evidence of the content validity of the instrument for use among people with type 2 diabetes mellitus receiving insulin therapy.

Musculoskeletal symptoms, psychosocial factors and work ability in Brazilian labor justice workers.

BACKGROUND: The implementation of the electronic judicial process (PJe) in recent years is associated with an increase in workload and stricter control through productivity targets in the Brazilian labor judiciary. OBJECTIVES: To evaluate the relations between musculoskeletal symptoms, psychosocial factors and work ability in civil servants of a labor justice body in the context of the PJe. METHODS: A cross-sectional exploratory study with a quantitative approach involving 449 workers. Sociodemographic, occupational and related data were collected through questionnaires validated in the Brazilian context. Data analysis was conducted by descriptive and inferential statistics: Mann-Whitney test, Spearman's correlation coefficient and multiple linear regression. RESULTS: There was a correlation between musculoskeletal symptoms and psychosocial factors (p < 0.05), as well as between both musculoskeletal symptoms and psychosocial factors with reduced work ability (p < 0.05). The multiple linear regression model pointed to the female gender and the dimensions "demands", "control" and "peer support" as related to the musculoskeletal symptoms. CONCLUSION: We highlight the importance of a broader approach, involving psychosocial factors in preventive actions related to musculoskeletal disorders considering the important relationship with work ability.

Musculoskeletal symptoms and work ability in a context of electronic judicial process.

INTRODUCTION: The recent transformations undergone by Brazilian labor court, especially with the introduction of electronic process of law (processo judicial eletrônico [PJe]), had a significant influence on how people work. OBJECTIVES: This study aimed to evaluate the occurrence of musculoskeletal symptoms and work ability in public sector employees working in a specialized labor court body. METHODS: A cross-sectional study was conducted with 449 workers, who provided demographic and occupational information and completed the Nordic Musculoskeletal Questionnaire (NMQ) and the Work Ability Index (WAI). RESULTS: Symptoms occurred more frequently in wrists/hands (62.4%), shoulders (62.1%), and neck (60.4%) in the past 12 months, and in the neck (29.8%), shoulders (29.4%), and wrists/hands (29.2%) in the past 7 days. The mean WAI score was 38.7 (6.4), and 31.4% of participants had poor or moderate work ability. WAI scores were poorer when participants had previous problems, and the number of body segments involved in complaints was greater among those with inadequate work ability. CONCLUSIONS: Higher frequency of musculoskeletal symptoms in wrists/hands, shoulders, and neck may be related to using PJe for work and is associated with poorer work ability scores, highlighting the importance of preventive interventions for work-related musculoskeletal disorders.

Effects of an intervention program with health education and hatha yoga on the health of professionals with musculoskeletal symptoms.

INTRODUCTION: Musculoskeletal and mental disorders are relevant in the workers' disease process, and ergonomic interventions that include guidance and physical exercise consist of strategies of health promotion. Integrative and complementary practices are presented as a possibility of promoting comprehensive care and yoga consists of a therapeutic alternative. OBJECTIVE: To evaluate the effects of an intervention including educational measures and hatha yoga in musculoskeletal pain, disability, and stress in professionals of a university hospital. METHODS: We selected 125 professionals with musculoskeletal symptoms of intensity ≥ 1 who did not practice yoga and randomly assigned them to intervention (n = 63) and control (n = 62) groups, requesting answers to the following questionnaires: initial characterization, the Nordic Musculoskeletal Questionnaire and a numeric scale, the Pain Disability Questionnaire, and the Perceived Stress Scale. The intervention group went through a 12-week program with educational measures and hatha yoga. At the end of the study period, both groups answered to the questionnaires once again. We compared data before and after the intervention and between groups. RESULTS: Both groups presented improvements after 12 weeks, but the difference between mean results obtained in the first and second data collections revealed that the levels of pain, disability, and stress decreased more strongly in the intervention group than in the control group. Considering that the intervention group began the program in worse clinical conditions, the program led to a reduction in the difference between groups, but this was not enough for the intervention group to reach better results than the control. CONCLUSIONS: The intervention promoted improvements in the intensity of pain, disability, and stress among the participants of the intervention group. Similar programs could be explored in the promotion of occupational health.

Ioga na saúde do trabalhador: revisão integrativa de estudos de intervenção / Yoga and occupational health: integrative review of intervention studies

Introdução: Efeitos do ioga no bem-estar físico e mental têm sido estudados em diversas áreas. Objetivos: Investigar e analisar o que a literatura científica dos dez anos subsequentes à publicação da Política Nacional de Práticas Integrativas e Complementares apresenta sobre resultados de intervenções utilizando ioga no ambiente de trabalho com trabalhadores. Método: Foram encontrados 10 artigos que se enquadraram nos critérios de inclusão, publicados de 2006 a 2015, disponíveis nas bases Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medical Literature Analyses and Retrieval System Online (MedLine), Web of Science, Scopus, Cochrane e Scientific Electronic Library Online (SciELO). Os artigos foram analisados quanto a ano de publicação, autoria, título, objetivos, resultados, conclusões e as intervenções caracterizadas quanto ao tipo de ioga, práticas envolvidas, frequência, duração da prática e da intervenção, instrumentos de medida e intervenções adicionais. Resultados: Os achados sugerem que o ioga está relacionado a efeitos físicos e psicológicos em trabalhadores de diferentes áreas, mas não foram encontrados benefícios sobre determinadas condições e a prática não proporciona o mesmo efeito positivo para todos. Verificou-se que a adesão dos trabalhadores aos programas propostos influencia os resultados das investigações. Muitos dos estudos não descreveram com clareza os programas. Conclusão: As características descritas evidenciam programas diferentes, permitindo uma síntese dos resultados, mas não uma comparação entre eles

Background: Effects of yoga on physical and mental health have been investigated in several fields. Objective: To investigate and analyze results of yoga interventions in the workplace reported along 10 years after the formulation of the National Policy of Integrative and Complementary Practices. Method: We located 10 studies published from 2006 to 2015 which met the inclusion criteria, included in databases Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medical Literature Analyses and Retrieval System Online (MEDLINE), Web of Science, Scopus, Cochrane and Scientific Electronic Library Online (SciELO). Analyzed variables were: publication year, authorship, title, aims, results, and conclusions. Interventions were characterized based on yoga style, practices implemented, frequency and duration of sessions, duration of intervention, measurement instruments, and additional interventions. Results: Our findings suggest that yoga has physical and psychological effects on workers from different professional categories. However, we did not find benefits for some conditions, and yoga practice does not have the same positive effects on all practitioners. Workers' adherence to programs influences the results of research. Many studies did not clearly describe the implemented programs. Conclusion: The characteristics of interventions show substantial differences among programs, which enable a synthesis, but not comparisons.

[Obstacles to return to work: Translation and cross-cultural adaptation of the questionnaire to the Brazilian context]. / Obstáculos para retorno ao trabalho: tradução e adaptação cultural do questionário para o contexto brasileiro.

The few existing questionnaires addressing return to work in Brazil are medical and/or psychological and do not examine work environment-related issues. The Obstacles to Return-to-Work Questionnaire (ORTWQ) is multidimensional, including biopsychosocial and environmental factors, and has proven useful in the return to work issue. The scope of this study is to describe the translation and cultural adaptation process of ORTWQ for use in the Brazilian context. It also discusses aspects related to work and the importance for health professionals to identify obstacles to return to work for occupational health vigilance. For the cultural adaptation process, there were five steps: translation, synthesis, back translation, evaluation by an expert committee and the pre-test process. Before the pre-test phase, the Content Validity Index was checked and was considered adequate when it was ≥ 0.8. The expression "increase working hours" was withdrawn from the questionnaire, since the partial returnto-work regime is rare in Brazil. The sample for the pre-test involved 40 individuals. The average time for completing ORTWQ was 14 minutes and the Brazilian version of ORTWQ proved to be adequate. Further studies should assess psychometric qualities of the questionnaire.

Os raros questionários existentes no Brasil que abordam retorno ao trabalho são físicos e/ou psicológicos e não abrangem questões relativas ao ambiente de trabalho. O Obstacles to Return-to-Work Questionnaire (ORTWQ) é multidimensional, inclui fatores biopsicossociais, ambientais e tem se mostrado útil como preditor de retorno ao trabalho. Este estudo tem como objetivo discutir a importância, para a Vigilância em Saúde do Trabalhador, de questionários que identificam os obstáculos para retorno ao trabalho, bem como traduzir e adaptar culturalmente o ORTWQ para uso no contexto brasileiro. Cinco etapas foram seguidas para a adaptação cultural: tradução, síntese, retrotradução, avaliação por comitê de especialistas e pré-teste. Antes do pré-teste, o Índice de Validade de Conteúdo foi verificado e considerado adequado quando ≥ 0,8. Foi retirado do questionário, o termo "aumentar as horas de trabalho", uma vez que o regime de retorno parcial ao trabalho é raro no Brasil. Participaram do pré-teste 40 sujeitos. A versão brasileira do ORTWQ mostrou-se adequada e o tempo médio para preenchimento foi de 14 minutos. Outros estudos devem avaliar as qualidades psicométricas desse questionário.

Psychometric Properties of the Freiburg Life Quality Assessment for Wounds Among Burned Patients.

BACKGROUND AND PURPOSE: Psychometric performance of quality of life (QoL) instruments must be evaluated prior to use. The Freiburg Life Quality Assessment for wounds (FLQA-w) emerged as one possible tool for burned patients. The purpose of this study was to assess the performance of FLQA-w in this population. METHODS: Composite reliability (CR) coefficients were estimated; convergent validity was assessed by Burns Specific Health Scale-Revised (BSHS-R), abbreviated QoL instrument (WHOQOL-BREF), and the visual analog scale; and responsiveness by comparing with the three visual analog scales. RESULTS: CR coefficients of FLQA-w domains were suitable (0.72-0.88). Correlations were strong and negative (r = -.51 to -.76). Responsiveness was adequate-statistically significant changes were observed. CONCLUSIONS: The results indicate reliable, valid, and responsive psychometric performance of the FLQA-w among burned patients.

Psychometric properties in instruments evaluation of reliability and validity. / Propriedades psicométricas na avaliação de instrumentos: avaliação da confiabilidade e da validade.

Measurement instruments play an important role in research, clinical practice and health assessment. Studies on the quality of these instruments provide evidence of how the measurement properties were assessed, helping the researcher choose the best tool to use. Reliability and validity are considered the main measurement properties of such instruments. Reliability is the ability to reproduce a result consistently in time and space. Validity refers to the property of an instrument to measure exactly what it proposes. In this article, the main criteria and statistical tests used in the assessment of reliability (stability, internal consistency and equivalence) and validity (content, criterion and construct) of instruments are presented, discussed and exemplified. The assessment of instruments measurement properties is useful to subsidize the selection of valid and reliable tools, in order to ensure the quality of the results of studies.

Instrumentos de medida desempenham um importante papel na pesquisa, na prática clínica e na avaliação de saúde. Estudos sobre a qualidade desses instrumentos fornecem evidências de como as propriedades de medida foram avaliadas, auxiliando o pesquisador na escolha da melhor ferramenta para utilização. A confiabilidade e a validade são consideradas as principais propriedades de medida de tais instrumentos. Confiabilidade é a capacidade em reproduzir um resultado de forma consistente, no tempo e no espaço. Validade refere-se à propriedade de um instrumento medir exatamente o que se propõe. Neste artigo são apresentados, discutidos e exemplificados os principais critérios e testes estatísticos empregados na avaliação da confiabilidade (estabilidade, consistência interna e equivalência) e validade (conteúdo, critério e construto) de instrumentos. A avaliação das propriedades de medida de instrumentos é útil para subsidiar a seleção de instrumentos válidos e confiáveis, de modo a assegurar a qualidade dos resultados dos estudos.

Validation of the Brazilian Version of the Job Satisfaction Survey Using Confirmatory Factor Analysis.

BACKGROUND AND PURPOSE: The purpose of this study was to evaluate the validity of the Brazilian version of the Job Satisfaction Survey (JSS) using confirmatory factor analysis supported by structural equation modeling in a sample of Brazilian nursing workers. METHODS: Data from 360 nursing workers were analyzed. Confirmatory factor analysis used partial least squares structural equation modeling (PLS-SEM). RESULTS: The results showed that the Brazilian version of the JSS presented better adjustment to the model after the removal of four items from the scale. According to confirmatory factor analysis, convergent and discriminant validities were confirmed. CONCLUSIONS: The Brazilian version of JSS showed strong evidence of construct validity through convergent and discriminant measures.

Psychometric Properties of the Obstacles to Return-to-Work Questionnaire in a Brazilian context.

Purpose To evaluate the psychometric properties of the Obstacles to Return-to-Work Questionnaire (ORTWQ) among Brazilian workers on sick-leave due to musculoskeletal disorders. Methods Confirmatory factor analysis was conducted to evaluate the factor structure validity of the ORTWQ. Model fit indices and salience of factor loadings were assessed. The convergent validity was estimated using the Average Variance Extracted (AVE) and Composite Reliability (CR). The correlational analysis was verified using the Spearman Correlation between the ORTWQ and other specific tools. Discriminant Validity, internal consistency, stability (test-retest) and floor/ceiling effect were also assessed. Results A total of 301 participants completed the ORTWQ with a mean age of 45.0 (9.9) years. After refinement, the factor structure indexes of the oblique model were [χ2/df = 1.8; CFI = 0.9; TLI = 0.9; PGFI = 0.7; PCFI = 0.8; RMSEA = 0.05 (90% CI 0.05-0.06)]. Only Depression, Physical Workload and Perceived Prognosis subscales presented suitable AVE indices: 0.63, 0.51 and 0.52 respectively. The correlations between ORTWQ and the other questionnaires were appropriate for almost all subscales. Reliability evaluation showed adequate estimates for all subscales except for the Worry Due to Sick-Leave (CR = 0.45; α = 0.44; ICC = 0.69). A higher order hierarchical model is suggested, in order to estimate an overall score to ORTWQ in a Brazilian population. Conclusions The psychometric properties of the Brazilian version of the ORTWQ were evaluated and after refinement, the validity, reliability and floor/ceiling effects indexes were suitable when applied to a sample of Brazilian workers on sick-leave due to musculoskeletal disorders. However, the factor structure presented some issues regarding convergent and discriminant validity.

Tradução e adaptação transcultural do psychological empowerment instrument para o contexto brasileiro / Translation and cultural adaptation of the psychological empowerment instrument for the Brazilian context / Traducción y adaptación cultural del instrumento de epoderamiento psicológico al contexto brasileño

Empoderamento psicológico está relacionado a uma sensação de motivação referente ao ambiente de trabalho. É um processo pelo qual os trabalhadores ganham o controle, expressam e satisfazem suas necessidades e são capazes de identificar, analisar e propor soluções aos problemas relacionados ao trabalho. Estudos comprovam que quando utilizado nos ambientes de trabalho de enfermagem, proporcionam resultados positivos, como: o aumento da satisfação no trabalho, comprometimento organizacional e redução do Burnout. O Psychological Empowerment Instrument (PEI) é um instrumento que avalia uma medida multidimensional de empoderamento psicológico no contexto do trabalho. Trata-se de um questionário composto de 12 itens e subdivido em quatro domínios (significado, competência, autodeterminação e impacto) com uma escala de medida do tipo Likert. Objetivo: discutir a importância da aplicação do empoderamento psicológico no ambiente da enfermagem, bem como disponibilizar uma versão do PEI para a língua portuguesa do Brasil, traduzindo e adaptando culturalmente o instrumento. Métodos: estudo metodológico, de corte transversal. O processo de adaptação cultural desenvolveu-se por meio de etapas recomendadas internacionalmente – tradução, síntese, retrotradução, avaliação por comitê de especialistas e o pré-teste. Resultados: o índice de validade de conteúdo foi considerado adequado (0,95). Os itens foram analisados pelos membros do comitê de especialistas que sugeriram alterações com o objetivo de facilitar a compreensão pela população. Foi também realizado um pré-teste com 31 sujeitos. Conclusão: o PEI se mostrou adequado para a população brasileira.

Psychological empowerment is related to a sense of motivation in the work environment. It is a process through which workers have their control increased, can express and satisfy their needs and are able to identify, analyze and propose solutions to problems related to their work. Studies have shown that when used in nursing work environments it provides positive results, such as increased job satisfaction, organizational commitment, and reduced burnout. The Psychological Empowerment Instrument (PEI) is an instrument that evaluates a multidimensional measure ofempowerment in occupational context. This is a questionnaire consisting of 12 items, subdivided into 4 domains (meaning, competence, self determinationand impact) with a Likert-type measurement scale. Objective: to discuss the importance of applying the psychological empowerment in nursing environment, as well as to provide a Brazilian Portuguese version of PEI, translating and culturally adapting the instrument. Methods: methodological and cross-sectional study. The adaptation process was developed through internationally recommended steps – translation, synthesis, back-translation, evaluation by an expert committee and pre-test. Results: the content validity index was considered appropriate(0.95). The items were analyzed by members of the expert committee, and they suggested some changes in order to facilitate understanding bythe population. It was also performed a pre-test with 31 subjects. Conclusion: the PEI has shown to be adequate for the Brazilian population. It is necessary for further studies to evaluate the psychometric properties of the instrument.

El empoderamiento psicológico se relaciona con la motivación para ejercer las tareas en el ambiente laboral. Es un proceso mediante el cuallos trabajadores adquieren control, expresan y satisfacen sus necesidades y son capaces de identificar y proponer soluciones a los problemaslaborales. Los estudios demuestran que cuando se utiliza en el ambiente de enfermería, aporta resultados positivos, como mayor satisfacciónen el trabajo, compromiso con la organización y disminución del desgaste. El Instrumento de Empoderamiento Psicológico (PEI) evalúa unamedida multidimensional de empoderamiento en el contexto laboral. Se trata de un cuestionario que consta de 12 ítems subdivido en 4 dominios(significado, competencia, autodeterminación e impacto) con una escala de medición tipo Likert. Objetivo: discutir la importancia de la aplicacióndel empoderamiento psicológico en enfermería, así como proporcionar la versión del PEI al idioma portugués de Brasil, traducir y adaptar culturalmente dicho instrumento. Métodos: Estudio metodológico transversal. El proceso de adaptación cultural siguió las etapas recomendadas internacionalmente – traducción, síntesis, retrotraducción, evaluación por el comité de expertos y prueba previa. Resultados: El índice de validezde contenido fue considerado apropiado (0,95). Los ítems fueron analizados por los miembros del comité de expertos quienes sugirieron algunas alteraciones para facilitar su comprensión. También se realizó una prueba piloto con 31 sujetos. Conclusión: El PEI es adecuado para la población brasileña. Se precisan otros estudios para evaluar las propiedades psicométricas del instrumento.

Quality of life of people with chronic ulcers.

INTRODUCTION: Patients with chronic ulcers have physical, social, and psychological changes that directly affect their quality of life. OBJECTIVES: To evaluate the quality of life and analyze the association between personal and health characteristics in patient quality of life for those with chronic ulcers. METHOD: A cross-sectional study, nonprobabilistic. The questionnaire to evaluate personal and health characteristics and the Ferrans and Power Quality of Life Index-Wound Version were used for the data collection. The sample consisted of 200 patients with chronic ulcers of several etiologies (venous ulcers, pressure ulcers, diabetic ulcers, and mixed) recruited at the basic health units in two cities in the South of Minas Gerais, Brazil. RESULTS: Overall, the study found that their quality of life was rated as good. There was a positive correlation between the different ages (P = 0.0165), number of children (P = 0.0083), and practice of religion (P = 0.0394) with quality of life.

Factor analysis of an instrument to measure the impact of disease on daily life. / Análise de fatores do instrumento de medida do impacto da doença no cotidiano.

OBJECTIVE: to verify the structure of factors of an instrument to measure the Heart Valve Disease Impact on Daily Life (IDCV) when applied to coronary artery disease patients. METHOD: the study included 153 coronary artery disease patients undergoing outpatient follow-up care. The IDCV structure of factors was initially assessed by means of confirmatory factor analysis and, subsequently, by exploratory factor analysis. The Varimax rotation method was used to estimate the main components of analysis, eigenvalues greater than one for extraction of factors, and factor loading greater than 0.40 for selection of items. Internal consistency was estimated using Cronbach's alpha coefficient. RESULTS: confirmatory factor analysis did not confirm the original structure of factors of the IDCV. Exploratory factor analysis showed three dimensions, which together explained 78% of the measurement variance. CONCLUSION: future studies with expansion of case selection are necessary to confirm the IDCV new structure of factors.
