RESUMEN

INTRODUCTION: Dyspnea during activities of daily living (ADL) is frequently reported by adults with asthma. However, instruments that specifically assess that in people with asthma have not yet been validated. OBJECTIVES: To investigate the validity and reliability, including standard error of measurement (SEM) and Minimum Detectable Change (MDC), of the London Chest Activity of Daily Living (LCADL) scale for adults with asthma. METHODS: Adults with asthma answered the LCADL scale which was performed twice by the same rater. Spirometry, 6-min walk test (6MWT), St George's Respiratory Questionnaire (SGRQ), modified Medical Research Council (mMRC) dyspnea scale, Asthma Quality of Life questionnaire (AQLQ), Asthma Control Test (ACT), and Glittre-ADL test were assessed. For statistical analyses, Spearman correlation, Wilcoxon test, Intraclass Correlation Coefficient (ICC), Cronbach's alpha coefficient, SEM, MDC were performed. RESULTS: Seventy participants were included (30% men, 44 ± 15 years old, BMI 27[23-31]kg/m2, FEV1 80 ± 17%predicted). For convergent validity, the LCADL scale was moderately correlated with SGRQ, AQLQ, and Glittre-ADL (r = 0.57, -0.46, and 0.41 respectively; p < 0.0001). The LCADL scale correlated weakly with the mMRC scale, ACT, and spirometry measures (-0.23

RESUMEN

Abstract The aim is to present validity evidence of the Brazilian-Portuguese Recovery Experience Questionnaire (REQ-PB) by applying a procedure to decentering cross-cultural scales translation and adaptation. First, we had a phase with bilingual experts, which assessed different criteria of translation quality. In sequence, we conducted the replication of the original research to achieve validity indicators in the Brazilian context. We carried out both Confirmatory Factor Analysis (to find structural validity indicators) and correlations with various external variables (to find convergent validity indicators). Step 1 showed promising results of decentering translation. In step 2 participated 164 workers and the CFA confirmed the four-factor model: psychological detachment from work, relaxation, mastery experience, and control over leisure time. The convergent validity showed a significant correlation with external variables. The REQ-PB showed adequate psychometric properties and may explain and compare empirical evidence of the recovery topic. We concluded that we have a good quality scale to be used in future research and integrated with other constructs to support interventions.

Resumo O objetivo é apresentar evidências da validade do Questionário de Experiência de Restauro em português brasileiro (REQ-PB) por meio da aplicação de um procedimento de descentralização para tradução e adaptação de escalas transculturais. Inicialmente, tivemos uma fase com especialistas bilíngues que avaliaram a qualidade da tradução utilizando diferentes critérios. Na sequência, realizamos a replicação da pesquisa original para alcançar os indicadores de validade no contexto brasileiro. Efetuamos tanto a análise fatorial confirmatória (para encontrar indicadores de validade estrutural) quanto correlações com variáveis externas (para encontrar indicadores de validade convergentes). O passo 1 mostrou resultados promissores na tradução descentralizada. No passo 2, participaram 164 trabalhadores e a análise fatorial confirmatória confirmou o modelo de quatro fatores: distanciamento psicológico do trabalho, relaxamento, experiência de domínio e controle do tempo livre. A validade convergente mostrou uma correlação significativa com variáveis externas. O REQ-PB mostrou propriedades psicométricas adequadas capazes de explicar e comparar evidências empíricas do tópico de restauro. Em resumo, a escala pode ser utilizada em pesquisas futuras e integrada aoutros construtos para orientar intervenções.

RESUMEN

INTRODUCTION: The Memory Complaint Scale (MCS-15) is a 15-item instrument to explore frequent forgetfulness in daily life in people with possible cognitive impairment. However, knowledge about its psychometric performance is limited. OBJECTIVE: The objective of this study was to know the dimensionality and internal consistency of the MCS-15 in Colombian older adults. METHODS: A probabilistic sample of 1,957 older adults from the general Colombian population was taken, aged between 60 and 98 years (mean = 71.0 ± 7.9), and 62.2% were women. Internal consistency (Cronbach's alpha and McDonald's omega) and dimensionality (exploratory and confirmatory factor analysis) were calculated for the original and ten-item versions. RESULTS: The 15-item version showed Cronbach's alpha and McDonald's omega of 0.91, and one dimension accounted for 45.3% of the variance. A version of ten items showed Cronbach's alpha and McDonald's omega of 0.89 and a single factor that explained 50.9% of the variance with better indicators in the confirmatory factor analysis. Convergence with the shortened Mini-Mental State Examination was rs = 0.43 (p < 0.001), and the Montreal Cognitive Assessment test was rs = 0.38 (p < 0.001). The nomological validity with the geriatric depression scale was rs = 0.44 (p < 0.001), and women scored higher than men (p < 0.001). CONCLUSIONS: The MCS-15 shows high internal consistency with poor dimensionality. However, a ten-item version shows high internal consistency and a clear one-dimensional structure. More research is needed: testing the performance against a structured interview for major cognitive impairment.

RESUMEN

BACKGROUND: Patient safety culture concerns the values, beliefs and standards shared by an organisation's health staff and other personnel which influence their care provision actions and conduct. Several countries have made a priority of strengthening patient safety culture to improve the quality and safety of health care. In this direction, measuring the patient safety culture through validated instruments is a strategy applied worldwide. The purpose of this study was to adapt transculturally and validate the HSOPSC 2.0 to Brazilian Portuguese and the hospital context in Brazil. METHODS: Of the various validated scales for measuring safety culture, the instrument most used internationally is the Hospital Survey on Patient Safety Culture (HSOPSC) developed by the United States Agency for Healthcare Research and Quality in 2004 and revised in 2019, when version 2.0 was released. Adaptation was conducted on a universalist approach and the adapted instrument was then applied to a sample of 2,702 respondents (56% response rate) comprising staff of a large general hospital in the city of São Paulo. Construct validity was investigated by Exploratory Structural Equation Modelling-within-Confirmatory Factor Analysis (ESEM-within-CFA) and reliability was measured in each dimension by means of Cronbach alpha coefficients. RESULTS: ESEM fit indexes showed good data fit with the proposed model: χ2 = 634.425 df = 221 χ2/df ratio = 2.9 p-value < 0.0000; RMSEA = 0.045 (90% C.I. = 0.041-0.050) and probability RMSEA < = .05 = 0.963; CFI = 0.986; TLI = 0.968. However, ten items had loads lower than 0.4. Cronbach alpha values were 0.6 or more for all dimensions, except Handoffs and information exchange ([Formula: see text]= 0.50) and Staffing and work pace ([Formula: see text] = 0.41). CONCLUSION: The psychometric properties of the Brazilian version were found to be satisfactory, demonstrating good internal consistency and construct validity as expressed by estimates of reliability and indexes of model fit. However, given factor loadings smaller than 0.4 observed in ten items and considering that the scale translated and adapted to Portuguese was tested on a single sample during the Covid-19 pandemic, the authors recognize the need for it to be tested on other samples in Brazil to investigate its validity.

RESUMEN

INTRODUCTION: Adults with asthma may have limitations in their activities of daily living (ADL) and among the most used tests to assess ADL, performance-based instruments such as the Glittre-Activities of Daily Living (Glittre-ADL) test are available. However, metric properties of this instrument have not yet been investigated in this population. OBJECTIVE: To verify the construct validity and reliability of the Glittre-ADL test in adults with asthma. METHODS: Fifty-eight adults with asthma had their ADL objectively assessed by Glittre-ADL test, which was performed twice by the same rater. Lung function (spirometry), functional exercise capacity (6-minute walk test, 6MWT), and quality of life (St George's Respiratory Questionnaire, SGRQ) were also assessed. RESULTS: Participants were 31% men; 43 ± 14 years; FEV1 74 ± 18% predicted. Performance in the Glittre-ADL test correlated with the 6MWT (r = -0.61; P < .0001) and had excellent intraclass correlation coefficient ICC3,1 = 0.95. Standard error of measurement was 23%, and the minimal detectable change was 29 seconds. Furthermore, the learning effect was 11 seconds (5.03%). CONCLUSION: The Glittre-ADL test is valid and reliable for assessing ADL in adults with asthma. However, considerable learning effect was observed and therefore the best of two measures can avoid underestimation.

RESUMEN

INTRODUCTION: The knee extension prone test (KEPT) can be a low-cost and affordable alternative for this assess knee hyperextension deficit. OBJECTIVE: To analyze concurrent validity and reliability of a new method for assessing knee extension prone (knee extension prone test; KEPT). METHODS: Participants were divided into two groups: Group 1 comprised healthy participants (HG) and Group 2 comprised participants with a history of knee injury (IG). Two examiners performed the following evaluations: (1) lateral knee goniometry, (2) anterior tibial inclinometry, (3) lateral photogrammetry in supine, (4) lateral photogrammetry in prone, and (5) KEPT. Concurrent validity was analyzed by Pearson's linear correlation coefficient (r), and intra- and inter-examiner reliability were analyzed by intraclass correlation coefficient (ICC). RESULTS: KEPT demonstrated good intra-examiner (ICC = 0.85, 95% CI = 0.75-0.89) and excellent inter-examiner (ICC = 0.92, 95% CI = 0.88-0.94) reliability. The standard error of measurement was 0.47° and 1.30° and the minimum detectable change was 2.35° and 6.5° for intra- and inter-examiner agreement, respectively. Concurrent validity of KEPT ranged from moderate to good (r = 0.54-0.78, p < 0.01). CONCLUSION: KEPT is a valid and reliable method for assessing knee hyperextension deficit in both healthy individuals and patients with knee injuries.

RESUMEN

OBJECTIVE: To verify the validity, reliability, learning effect, Minimal Detectable Change (MDC), and feasibility of four functional tests (4-Meter Gait Speed [4MGS], Timed Up-and-Go [TUG], Sit-To-Stand [STS], and Short Physical Performance Battery [SPPB]) for adults with asthma. METHODS: In this cross-sectional study, fifty-two subjects with stable asthma underwent three sets of different functional tests protocols (4MGS, TUG, STS, SPPB) in a random order by two raters. For validation analysis, tests were compared with a sex-age matched control group without asthma and correlated with the Six Minute Walking Test (6MWT), and peripheral muscle strength, as well as with quality of life and asthma control questionnaires. Intra-rater and inter-rater reliability, MDC, and feasibility were verified. RESULTS: Adults with asthma presented worse results than controls in the functional tests, except for SPPB. All functional tests were significantly correlated with 6MWT (0.45 < r < 0.67) and peripheral muscle strength (0.32 < r < 0.63), but not with quality of life and asthma control (0.02 < r < 0.17). The tests presented good to excellent intra-rater Intraclass Correlation Coefficients (ICC ≥ 0.75 for all). In all tests, a considerable learning effect and variability of measurement was observed, therefore, the best of two measurements should be used. MDC ranged from 15 to 31% and all tests were performed in a short time, small space, and without clinical adverse events. CONCLUSION: Different protocols of 4MGS, TUG, STS, and SPPB are valid, reliable, and feasible to assess the functional capacity of adults with asthma. These tests are quick and practical new alternatives for assessing functional capacity in this population.

RESUMEN

The objective of this study was to evaluate the validity and reliability of OTESSED, an online test for the self-detection and prevention of risk factors for eating disorders and related problems, such as depression, social anxiety, and self-injury, in samples of male and female adolescents. Participants formed a non-probability sample of N = 577 high school students. The mean ages of boys and girls were the same (Mage = 15.61; SD = 0.73). Among the main results, scales of depression, self-injury, social anxiety, and risky eating behavior (REB) with construct validity (CFA) were obtained. The first two showed the same structure (two factors per sex), with an appropriate reliability omega value (0.92), and a similar percentage of explained variance (≥50). The REB scale presented two factors for boys and three for girls, with an appropriate omega value (0.88) and explained variance percentage (0.56). The instrument validation process was completed, meeting the discriminant validity criterion for each scale of the OTESSED.

RESUMEN

The aim of this study is to present a short form of the I COPPE scale of multidimensional well-being. We conducted two studies, which include four samples collected across three countries, namely United States, Argentina, and Italy. In the pilot study we tested during the data analysis phase whether it was feasible to reduce the full I COPPE scale by omitting the items dealing with past well-being. Prompted by the positive results of the pilot study, we launched a final validation study with a sample of 2682 Italian people who completed the I COPPE scale short form, which is designed without items referring to past well-being. Results from a series of confirmatory factor analyses show that the I COPPE scale short form presents acceptable levels of construct validity and reliability. Moreover, the 7-factor correlated-trait model proved to be the best fit for the data. We discuss advantaged of using the I COPPE scale short form along with limitations and future recommendations.

RESUMEN

Improvement in rider mobility represents an important functional gain for people with disabilities undergoing hippotherapy. However, there is no validated measuring instrument to track and document the rider's progress in riding activities. In this study, we aimed to develop and establish validity evidence for an instrument to assess hippotherapy participants' mobility on horseback. We report on this development through the stages of: (a) content validation, (b) construct validation, (c) inter- and intra-rater reliability and (d) internal consistency analysis. We evaluated its factor structure with exploratory factor analyses, calculated values for inter- and intra-rater reliability using the intra-class correlation coefficient, and calculated its internal consistency using Cronbach's alpha. We followed recommendations by the Guidelines for Reporting Reliability and Agreement Studies. We found good inter-rater reliability (intra-class correlation coefficient - ICC = 0.991-0.999) and good intra-rater reliability (ICC = 0.997-1.0), and there was excellent internal consistency (Cronbach's α = 0.937-0.999). The instrument's factor structure grouped its three domains into one factor. As this instrument is theoretically consistent and has been found to be appropriate and reliable for its intended use, it is now available for the measurement of horseback mobility among hippotherapy riders.

RESUMEN

El entorno laboral de los profesionales de enfermería es un área temática de gran interés para organizaciones internacionales en salud, organizaciones profesionales internacionales y locales, académicos, investigadores y directores o gerentes de enfermería, por la mediación o el impacto que estos entornos pueden tener en los resultados personales y profesionales de los enfermeros, en la calidad de la atención que se brinda a los pacientes y en los resultados de las organizaciones proveedoras de servicios de salud. Por lo anterior, existe el gran desafío de establecer entornos laborales saludables para mejorar la práctica de los enfermeros. Para promover la investigación empírica de los entornos laborales saludables de los enfermeros de práctica asistencial en el ámbito hospitalario, se desarrolló el instrumento ENLASA-Enfermería empleando un diseño de métodos mixtos secuencial exploratorio de tres fases. En la primera fase se adelantó la definición del concepto y la identificación de sus características, iniciando con una sub-fase de revisión teórica, continuando con una subfase de abordaje cualitativo con enfermeros y finalmente una sub-fase analítica para interconectar los hallazgos teóricos y cualitativos. En la segunda fase se generó un banco de ítems organizado en dos dimensiones (parte A: componentes estructurales organizacionales y parte B: dimensión de procesos organizacionales) que fue sometido a una revisión por expertos para estimar la validez facial y de contenido, y posteriormente se realizó una prueba piloto con una muestra de 22 enfermeros. Finalmente, en la tercera fase se aplicó el instrumento a una muestra de 307 enfermeros clínicos del ámbito hospitalario de diferentes municipios y ciudades de Colombia, con lo cual se realizó una evaluación de las propiedades métricas en términos de validez de constructo y confiabilidad. Los resultados obtenidos permitieron clasificar cada una de las partes de ENLASAEnfermería como satisfactorias en términos de validez facial y de contenido con índices globales superiores a 0,80 en las variables evaluadas por cada parte; con consistencia interna satisfactoria (Alfa de Cronbach parte A: 0,930 y parte B: 0,944) y con una estructura interna que permitió reconocer los elementos conceptuales de un entorno laboral saludable que respaldan su contenido. Se concluyó que ENLASA-Enfermería es un instrumento válido y confiable, prometedor para la investigación y la evaluación de los entornos laborales saludables de enfermeros clínicos en el ámbito hospitalario en Colombia.

The work environment of nursing professionals is a subject area of great interest to international health organizations, international and local professional organizations, academics, researchers and nursing directors or managers due to the mediation or the impact that these environments may have in the results of the professionals nursing, in the quality of care provided to patients and in the results of health service provider organizations. Therefore, there is the great challenge of establishing healthy work environments to improve the practice of professionals nursing. To promote empirical research on healthy work environments for nurses in care practice in the hospital setting, the ENLASA-Nursing instrument was developed using a three-phase exploratory sequential mixed methods design. In the first phase, the definition of the concept and the identification of its characteristics were advanced, starting with a sub-phase of theoretical review, continuing with a subphase of qualitative approach with nurses and finally an analytical sub-phase to interconnect the theoretical findings and qualitative. In the second phase, a bank of items organized in two dimensions (part A: organizational structural components and part B: organizational processes dimension) was generated, which was subjected to a review by experts to estimate facial and content validity and subsequently carried out a pilot test with a sample of 22 nurses. Finally, in the third phase, the instrument was applied to a sample of 307 clinical nurses from the hospital environment of different municipalities and cities in Colombia, with which an evaluation of the metric properties in terms of construct validity and reliability was carried out. The results obtained allowed classifying each of the parts of ENLASA-Nursing as satisfactory in terms of facial validity and content with indices global above 0.80 in the variables evaluated; with satisfactory internal consistency (Cronbach's Alpha part A: 0,930 and part B: 0,944) and with an internal structure that demonstrated relationships between items, subdimensions and dimensions, confirming the existence of the healthy work environment construct measured by the instrument. It was concluded that ENLASA-Nursing is a valid and reliable instrument, promising for the research, establishment and evaluation of healthy work environments of clinical nurses in the hospital setting in Colombia.

RESUMEN

INTRODUCTION AND OBJECTIVE: The Brazilian version of Falls Efficacy Scale (FES-BR) used to assess the fear of falling, has not yet been validated in patients with Chronic Obstructive Pulmonary Disease (COPD). The aim of the present study was to investigate the construct validity and reliability of the (FES-BR) in patients with COPD. METHODS: A cross-sectional study involving subjects with COPD, aged between 48 and 83 years. Data were collected by two independent and blind assessors. Construct validity was assessed using the Spearman's rank correlation coefficient between FES-BR and Berg Balance Scale, Downton fall risk index, Timed Up and Go Test (TUG), hand-grip strength (HGS), Five Times Sit to Stand Test (FTSST) and 6-Minute Walk Test (6MWT). Reliability was measured by the Cronbach's alpha coefficient, Intraclass Correlation Coefficient (ICC), and Bland-Altman plot. RESULTS: The study included 60 subjects aged 68.3 ±â€¯9.9 years and FEV1 56.0 ±â€¯19.3. The correlations were significantly strong between FES-BR and the Berg Balance Scale (r = -0.66), TUG (r = 0.64), HGS (r = 0.61) and FTSST (r = 0.62); and moderate between FES-BR and the Downton fall risk index (r = 0.38) and the 6MWT (r = -0.48). All correlations had p < 0.001. Intra-rater [ICC = 0.94, (95% CI = 0.91-0.96)] and inter-rater [0.97, (95% CI = 0.97-0.98)] reliability were considered excellent. CONCLUSIONS: The Brazilian version of FES was valid and reliable in assess fear of falling in subjects with COPD.

RESUMEN

BACKGROUND: The Colorado Adult Joint Assessment Scale (CAJAS) is designed to assess joint health in adults with hemophilia. The CAJAS comprises nine items (swelling, muscle atrophy, axial deformity, crepitus, range of motion, contracture, instability, strength, gait) and assesses six joints. OBJECTIVE: To assess CAJAS content validity and psychometric properties. PATIENTS/METHODS: Data were obtained from the Trial to Evaluate the Effect of Secondary Prophylaxis With rFVIII Therapy in Severe Hemophilia A Adult and/or Adolescent Subjects Compared to That of Episodic Treatment (SPINART) study and a separate CAJAS validation study. CAJAS assessments in SPINART were performed by physical therapists (PTs) from the United States, Romania, Bulgaria, and Argentina. In the validation study, content validity was assessed from interviews with six PTs at three US hemophilia centers; cultural equivalence was assessed with seven non-US PTs from SPINART. Reliability data were collected from 30 subjects at four US centers. Test-retest reliability was evaluated by having the same PT perform CAJAS examinations at two visits, 7-10 days apart. Inter-rater reliability was assessed by comparing CAJAS scores of two different PTs performing separate examinations of the same patient several hours apart at the same visit. Psychometric properties were assessed using SPINART and validation study data. RESULTS: The CAJAS demonstrated good content validity. Test-retest reliability was high (intraclass correlation coefficient, 0.98), as was inter-rater reliability (intraclass correlation coefficient, 0.88). Internal consistency reliability was strong (α = .90). The CAJAS demonstrated good convergent/divergent validity, known-groups validity, and ability to detect change. CONCLUSIONS: The CAJAS is a valid and reliable measure of joint health in adults with moderate-severe hemophilia and is appropriate for use in clinical practice.

RESUMEN

Abstract Introduction: Anxiety sensitivity plays a prominent role in the etiology of anxiety disorders. This construct has attracted widespread interest from experts and researchers. The Anxiety Sensitivity Index (ASI-3) is the most common scale for measuring anxiety sensitivity. Objective: To analyze the psychometric properties and factor structure of the ASI-3 in Iranian student samples. Methods: 220 students (135 women, 85 men) from Kermanshah University of Medical Sciences were selected by the convenience sampling method to evaluate the psychometric properties and analyze the factor structure of the ASI-3. The subjects were also asked to complete the Acceptance and Action Questionnaire-II (AAQ-II), Whiteley Index, Intolerance of Uncertainty, and Neuroticism scales. LISREL and SPSS were used to analyze the data. Cronbach's alpha and correlation coefficients were calculated and confirmatory factor analysis was conducted. Results: The results of the confirmatory factor analysis revealed a three-factor structure with physical, cognitive, and social components (comparative fit index = 0.94; normed fit index = 0.91; root mean square error of approximation = 0.09). The ASI-3 had positive and significant correlations with health anxiety (0.59), intolerance of uncertainty (0.29), and neuroticism (0.51). Furthermore, the ASI-3 had a negative and significant correlation with the AAQII (-0.58). Cronbach's alpha coefficients for the whole scale and for the physical, cognitive, and social concerns factors were 0.90, 0.74, 0.79, and 0.78, respectively. The invariance of the index was significant compared to the original English version. Conclusion: In general, the results support the adequacy of the psychometric properties of the Persian version of the ASI-3. Theoretical and applied implications will be discussed.

Resumo Introdução: A sensibilidade à ansiedade desempenha um papel proeminente na etiologia dos transtornos de ansiedade. Esse construto tem atraído grande interesse entre especialistas e pesquisadores. O Anxiety Sensitivity Index (ASI-3; em português, Escala de Sensibilidade à Ansiedade) é a medida mais utilizada para medir sensibilidade à ansiedade. Objetivo: Analisar as propriedades psicométricas e a estrutura fatorial do ASI-3 em estudantes iranianos. Métodos: Para avaliar as propriedades psicométricas e analisar a estrutura fatorial do ASI-3, 220 estudantes (135 mulheres, 85 homens) da Kermanshah University of Medical Sciences, Irã, foram selecionados via amostragem por conveniência. Eles foram solicitados a completar os seguintes instrumentos: Acceptance and Action Questionnaire-II (AAQ-II), Whiteley Index, Intolerance of Uncertainty e Neuroticism. Os programas LISREL e SPSS foram utilizados para analisar os dados. Alfa de Cronbach e coeficientes de correlação foram calculados, e foi realizada análise fatorial confirmatória. Resultados: Os resultados da análise fatorial confirmatória revelaram uma estrutura de três fatores, incluindo componentes físicos, cognitivos e sociais [comparative fit index (CFI) = 0,94; normed fit index (NFI) = 0,91; root mean square error of approximation (RMSEA) = 0,09]. O ASI-3 demonstrou correlações positivas e significativas com ansiedade em relação à saúde (0,59), intolerância à incerteza (0,29) e neuroticismo (0,51). Além disso, o ASI-3 teve uma correlação negativa e significativa com o AAQII (-0,58). Os coeficientes alfa de Cronbach para toda a escala e para os fatores preocupação física, cognitiva e social foram 0,90, 0,74, 0,79 e 0,78, respectivamente. A invariância do índice foi significativa em relação à versão original. Conclusão: Em geral, os resultados sugerem que as propriedades psicométricas da versão persa do ASI-3 são adequadas. Implicações teóricas e práticas serão discutidas.
