Patient Health Questionnaire-9: A clinimetric analysis.

OBJECTIVE: The Patient Health Questionnaire-9 (PHQ-9) is a widely used self-report measure of depression whose psychometric properties were found to be merely acceptable. Insufficient attention has been devoted to its clinimetric validity, while its clinical utility is still debated, particularly for assessing depression severity. This is the first study to test the PHQ-9 construct validity and clinical utility based on clinimetric principles. METHODS: An online survey of 3,398 participants was conducted. Item response theory models (Rasch and Mokken analyses) were used to assess the PHQ-9 validity and determine its clinical utility. RESULTS: Fit to the Rasch model was achieved after adjusting the sample size. Items 2, 4, 6, and 9 over-discriminated, while items 1, 5, and 7 under-discriminated. Local dependency between items 2 and 6 was indicated. The PHQ-9 was not unidimensional. A Loevinger's coefficient of 0.49 was found, indicating an acceptable level of scalability. CONCLUSION: The PHQ-9 is an instrument with potential clinical utility as an overall index of depression, mainly for screening purposes. Substantial revision, particularly in the wording of over- and under-discriminating items, is needed.

Psychometric review of the perceived stress scale under CFA and Rasch models in Lima, Peru.

Stress is a public health disease that is increasing rapidly in the population worldwide, so it is necessary to take measures for detection and evaluation, through short scales. The purpose of the study was to analyze the psychometric properties of the Perceived Stress Scale (PSS) in a sample made up of 752 people with an age range of 18 to 62 years (M = 30.18, DE = 10.175), of whom 44% (331) were women and 56% (421) men, from Lima, Peru. The results, by means of confirmatory factor analysis and the Rasch model, confirmed the global adjustment of a 12-item (PSS-12) version with the presence of two orthogonal factors independent of each other, and also demonstrated the metric equivalence according to gender and adequate internal consistency. These results allow us to recommend the use of the PSS-12 in the Peruvian population for the measurement of stress.

Dual career competency questionnaire for athletes: psychometric properties of the Brazilian version.

Introduction: No studies have yet attempted to quantitatively measure the competencies of Brazilian student-athletes. Consequently, there are no validated measures suitable for this purpose. The aim of this research was to examine the psychometric properties and assess content validity, factorial validity and evidence based on response processes of the Brazilian version of the Dual Career Competency Questionnaire for Athletes (DCCQ-A). Methods: The Brazilian DCCQ-A was administered to 745 student-athletes (Mage = 17.3 ± 5.4; 54% female; 8% student-athletes with disabilities). Results: Content validity coefficient analysis indicated clarity of language, theoretical pertinence, and practical relevance of the Brazilian DCCQ-A items. Confirmatory factorial analysis revealed excellent goodness-of-fit indices of the 4-factor structure model. Polytomous Rasch analysis demonstrated an acceptable adjustment of the items and good organization in the item response categories. Discussion: Considering the psychometric strength of the Brazilian DCCQ-A, this instrument can contribute to the practical and research applicability of sport psychology, providing support to those involved with student-athletes' dual career by identifying their competencies and possible limitations.

Escala de Percepción de Reforzamiento Medioambiental (EROS): evidencias de validez en una muestra colombiana

Introducción: El objetivo de esta investigación fue confirmar la estructura interna de la Environmental Reward Observation Scale (EROS) y recoger evidencias de su relación con otros constructos en una muestra colombiana de 902 adultos que consintieron participar voluntariamente. Método: Se realizaron análisis psicométricos con Teoría Clásica de los Test y el modelo de Rasch. Se recolectaron evidencias de validez de la estructura interna y de la relación de las puntuaciones con otras variables. Resultados: Se obtuvieron buenos índices en los coeficientes alfa y omega de McDonald, nueve de los 10 ítems tuvieron buenos ajustes en los índices infit y outfit, y el ítem ocho presentó DIF en el nivel educativo. Se confirmó la estructura unidimensional de la EROS y fue invariante respecto al sexo y nivel educativo. Los puntajes tuvieron correlaciones de magnitud alta con sintomatología emocional y variables afines a la Activación Conductual. Conclusiones: La EROS presentó altas calidades psicométricas para su uso en población colombiana; sin embargo, se recomienda su uso solo para evaluación de tamizaje, porque los niveles de información están centrados en un área reducida a lo largo de la métrica logit.

Introduction: The aim of this research was to confirm the internal structure of the Environmental Reward Observation Scale (EROS) and to collect evidence of its relationship with other constructs in a Colombian sample of 902 adults who voluntarily consented to participate. Method: Psychometric analyses were performed using Classical Test Theory and the Rasch model. Evidence of validity based on internal structure and relations of scores with other variables was collected. Results: Good indexes were obtained in McDonald's Alpha and Omega coefficients, 9 of the 10 items had good adjustments in the Infit and Outfit indexes, and item 8 presented DIF in the educational level. The unidimensional structure of the EROS was confirmed and was invariant with respect to sex and educational level. Scores had high magnitude correlations with emotional symptomatology and variables related to Behavioral Activation. Conclusions: The EROS presented high psychometric qualities for its use in the Colombian population; however, its use is recommended only for screening assessment because the levels of information are centered in a reduced area along the Logit scaling.

Translation and cross-cultural adaptation of the Brazilian version of the PM-Scale: A specific measure of participation after stroke.

BACKGROUND: The PM-Scale was developed specifically to assess participation in individuals after stroke based on the concepts contained in the International Classification of Functioning, Disability and Health. However, this measure is only available in English and French. OBJECTIVE: To translate and cross-culturally adapt the PM-Scale to Brazilian Portuguese, followed by the validation and testing of reliability of the translated version. METHODS: The translation process followed standard guidelines. Preliminary test-retest reliability was determined using the intraclass correlation coefficient (ICC2,1). The Rasch model was employed to analyse the validity, unidimensionality, invariance, and internal consistency of the Brazilian version of the PM-Scale. RESULTS: The final translated version of the PM-Scale presented appropriate semantic, idiomatic, cultural, and conceptual equivalence. The preliminary analysis revealed excellent intra-observer and inter-observer reliability (ICC2,1 = 0.91; 95%CI: 0.83, 0.95 and ICC2,1 = 0.81; 95%CI: 0.64, 0.89, respectively). The analysis of the Rasch model revealed only one erratic item. An excellent overall fit was found for items (mean ± SD = 0.01 ± 1.02) and adequate fit was found for persons (mean ± SD = 1.16 ± 0.88). Internal consistency was considered adequate (person separation index = 1.77, reliability = 0.76). No significant invariance was found with regards to the personal characteristics of the sample (p > 0.05). CONCLUSION: The Brazilian version of the PM-Scale is a valid, unidimensional, linear, reliable scale for measuring participation in stroke survivors and can be administered in less than five minutes.

Psychometric Indicators of the Pro-environmental Attitudes' Questionnaire: Colombian Version.

The detrimental effect of human behavior on the environment is undeniable. Attitudes are recognized as a predictor of the pro-environmental behavior; therefore, having good quality tools in Colombia to measure them is strategic to assess interventions. This study aims to establish psychometric indicators for the pro-environmental attitudes questionnaire (PEAQ) Colombian version to a sample of 415 volunteers (53% women and 47% men) aged 18-70 years (M = 40.28; SD = 14.06). We used the 28-item PEAQ already linguistically adapted for Colombia. We applied the following questionnaires: Environmental awareness (EA) (11 items), environmental values (EV) (4 items), and the pro-environmental at work questionnaire (PEWQ) (31 items). We used a one-parameter Rasch model and Winsteps program to assess the PEAQ's one-dimensionality and item statistics by gender, and estimated Spearman's rho coefficient between the PEAQ scores and the scales for concurrent validity. The PEAQ in this study has 24 items because 4 items did not fit into the Rasch model criteria. Its one-dimensionality was supported by an explained variance (43%) and the first residual variance (12%). The coefficients, α = 0.95 and Ω = 0.95; Rasch for persons = 0.90; and Rasch for items = 0.95. The correlation between the PEAQ and the EC, EV, and PEWQ scales were Spearman's rho coefficient = 0.859 (p ≤ 0.001), 0.795 (p ≤ 0.001), and 0.885 (p ≤ 0.001), respectively. Thus, the PEAQ Colombian version's psychometric indicators support it as a valid and reliable instrument to measure pro-environmental attitudes in this country.

Test of Gross Motor Development-3: Item Difficulty and Item Differential Functioning by Gender and Age with Rasch Analysis.

The assessment of motor proficiency is essential across childhood to identify children's strengths and difficulties and to provide adequate instruction and opportunities; assessment is a powerful tool to promote children's development. This study aimed to investigate the hierarchal order of the Test of Gross Motor Development-Third Edition (TGMD-3) items regarding difficulty levels and the differential item functioning across gender and age group (3 to 5, 6 to 8, and 9 to 10 years old). Participants are 989 children (3 to 10.9 years; girls n = 491) who were assessed using TGMD-3. For locomotor skills, appropriate results reliability (alpha = 1.0), infit (M = 0.99; SD = 0.17), outfit (M = 1.18; SD = 0.64), and point-biserial correlations (rpb values from 0.14 to 0.58) were found; the trend was similar for ball skills: reliability (alpha = 1.0), infit (M = 0.99; SD = 0.13), outfit (M = 1.08; SD = 0.52); point-biserial correlations (rpb values from 0.06 to 0.59) were obtained. Two motor criteria: gallop, item-1, and one-hand forehand strike, item-4, were the most difficult items; in contrast, run, item-2, and two-hand catch, item-2, were the easiest items. Differential item functioning for age was observed in nine locomotor and ten ball skills items. These items were easier for older children compared to younger ones. The TGMD-3 has items with different difficulty levels capable of differential functioning across age groups.

Normatização da Bateria de Provas de Raciocínio (BPR-5) usando a Teoria de Resposta ao Item / Standardization of the Reasoning Tests Battery (BPR-5) using Item Response Theory / Estandarización de la Batería de Pruebas de Razonamiento (BPR-5) usando la teoría de respuesta al ítem

A Bateria de Provas de Raciocínio (BPR-5) é um instrumento bastante utilizado para avaliação da inteligência no Brasil, possuindo três formas: infantil (1º ao 6º ano do Ensino Fundamental), Forma A (7º ao 9º ano do Ensino Fundamental) e Forma B (Ensino Médio e Superior). Visando a possibilidade de comparar os resultados entre sujeitos que respondem a formas diferentes, o presente estudo objetivou: (a) calibrar os itens das três formas pelo modelo de Rasch, realizando a equalização por itens comuns de modo a obter uma escala equiparável para as três formas, (b) atualizar as normas expandindo a representatividade das amostras e produzindo-se normas para diferentes combinações de idade, escolaridade e sexo, (c) descrever padrões de desenvolvimento da inteligência a partir da escala, comum, produzida entre 6 e 52 anos. Dois estudos foram relatados, o primeiro sobre a calibração dos parâmetros segundo o modelo de Rasch indicando um bom ajuste ao modelo. O segundo estudo exemplificou a utilização de regressão múltipla para criação de normas para testes psicológicos, considerando as variáveis idade, escolaridade e sexo como preditoras dos escores na BPR-5. Essas três variáveis tiveram efeitos significativos explicando 8% (Raciocínio Abstrato), 13% (Raciocínio Verbal), 12% (Raciocínio Espacial), 8% (Raciocínio Numérico) e 22% (Raciocínio Mecânico).(AU)

The Reasoning Tests Battery (BPR-5) is widely used in Brazil for the assessment of intelligence. It has three different forms: children (1st to 6th grade of elementary school), Form A (7th to 9th grade of elementary school) and Form B (high school and higher education). This study describes the steps followed to create a common metric across the forms. It aimed to: (a) calibrate the items of the three forms using Rasch model, link items and equate subjects' scores across forms using the anchoring of common items method, (b) update the norms by expanding the representativeness of the samples by producing norms for different combinations of age, education and sex, and (c) describe the developmental patterns of the BPR-5 subtests across a wide age range, from 6 to 52 years. We present two studies, the first reporting the calibration of item and person parameters with the Rasch model and a good fit to the model. The second illustrated the use of multiple regression analysis to create norms for the psychological tests considering the variables age, education and gender as predictors of the BPR-5 scores. These three variables had significant effects explaining 8% (Abstract Reasoning), 13% (Verbal Reasoning), 12% (Spatial Reasoning), 8% (Numerical Reasoning) and 22% (Mechanical Reasoning) of the variance. (AU)

Peabody Developmental Motor Scales-2: The Use of Rasch Analysis to Examine the Model Unidimensionality, Motor Function, and Item Difficulty.

The Peabody Developmental Motor Scales-Second Edition (PDMS-2) is a valid and reliable instrument used in several countries, including Brazil, to assess gross and fine motor skills and identify motor deficits and eligibility for intervention for children with and without disabilities. However, the analysis of PDMS-2 items regarding the unidimensionality of the model, order of item difficulty, and whether the items portray the children's developmental trajectories still lacks investigation. Therefore, this study aims to: (1) analyze the unidimensionality of PDMS-2, (2) verify the model's capacity to explain the variance in the motor function responses, and (3) identify the level of difficulty of the items for Brazilian children. Children (n = 637; 51% girls) newborn to 71 months (M age = 21.7, SD = 18.6) were assessed using the PDMS-2. The Rasch analysis was conducted; the indexes of infit and outfit, and the point-biserial correlations coefficient were analyzed. The model unidimensionality was investigated using percentages of variance in the Rasch model (40% of variance). Results indicated that (1) for reflexes subscale, 62.5% of the items had correlations with the factor above 0.60, and two items had unadjusted infit and outfit; (2) for stationary subscale, 83.3% of the correlations of the items with the factor were above 0.50, and one item had unadjusted infit and outfit; (3) for locomotion subscale, 80.0% of the correlation of the items with the factor were above 0.50; all items had adequate infit and outfit; (4) for object manipulation subscale, 79.9% of the correlation of the items with the factor were above 0.50, and one item had unadjusted infit and outfit; (5) for grasping subscale, 92.3% of the correlation of the items with the factor were above 0.50, and one item had unadjusted infit and outfit; and (6) for the visual-motor integration subscale, 73.6% of the correlation of the items with the factor were above 0.50, and six items had unadjusted infit and outfit. The items with unadjusted fit were removed for further analysis. No changes in reliability and separation of items and people scores were observed without the unadjusted items; therefore, all items were maintained. A unidimensional model was found, and the reliability and discriminant capability of the items were adequate, and all items should be used to assess children. The PDMS-2 is appropriate for assessing Brazilian children.

Psychometric Properties of the Zarit Burden Interview in Informal Caregivers of Persons With Intellectual Disabilities.

Intellectual disability leads to a loss of autonomy and a high level of dependence, requiring support from another person permanently. Therefore, it is necessary to incorporate the assessment of caregiver burden in healthcare actions, to avoid putting the health of caregivers and patients at risk. In this sense, the study aimed to analyze the internal structure of the Zarit Burden Interview (ZBI) in a sample of caregivers of people with intellectual disabilities, to provide convergent and discriminant evidence with a measure of the risk of maltreatment, and to estimate the reliability of the scores from the Classical Test Theory and the Rasch Measurement Theory. The study was instrumental. The sample consisted of 287 Peruvian informal primary caregivers of persons diagnosed with intellectual disabilities. To collect validity evidence, the internal structure (confirmatory factor analysis, CFA) and the relationship with other variables (convergent and discriminant evidence) were used, while reliability was estimated through the omega coefficient and Rasch analysis. The internal structure of the ZBI corroborated a unidimensional structure. In terms of convergent and discriminant evidence, the scale presents adequate evidence. Reliability levels were also good. Previously, the psychometric properties of the ZBI have not been studied in caregivers of people with intellectual disabilities, and it represents the first study of the scale in Peru. The results obtained will allow the use of this scale to design actions in the work with caregivers and studies to understand the psychology of the caregiver.

Burnout Assessment Tool (BAT): Validity Evidence from Brazil and Portugal.

The Burnout Assessment Tool (BAT) has been gaining increased attention as a sound and innovative instrument in its conceptualization of burnout. BAT has been adapted for several countries, revealing promising validity evidence. This paper aims to present the psychometric properties of the Brazilian and Portuguese versions of the BAT in both the 23-item and 12-item versions. BAT's validity evidence based on the internal structure (dimensionality, reliability, and measurement invariance) and validity evidence based on the relations to other variables are the focus of research. A cross-sectional study was conducted with two non-probabilistic convenience samples from two countries (N = 3103) one from Brazil (nBrazil = 2217) and one from Portugal (nPortugal = 886). BAT's original structure was confirmed, and it achieved measurement invariance across countries. Using both classic test theory and item response theory as frameworks, the BAT presented good validity evidence based on the internal structure. Furthermore, the BAT showed good convergent evidence (i.e., work engagement, co-worker support, role clarity, work overload, and negative change). In conclusion, the psychometric properties of the BAT make this freely available instrument a promising way to measure and compare burnout levels of Portuguese and Brazilian workers.

Mental Health of Teachers Who Have Teleworked Due to COVID-19.

The impact of the COVID-19 pandemic on education included school closures and the implementation of virtual teaching and teleworking without the knowledge or resources needed to do so. This situation accentuated the inequality in accessing quality education and generated high rates of stress, anxiety, and general discomfort in teachers. This study aimed to explore the mental health of teachers who were forced to telework because of COVID-19, and to analyze the association with sociodemographic, teacher-related, and working conditions. The sample was 278 classroom teachers in Chile who teleworked more than 50% during the 2020 academic year. The participants were mostly women (82%) who entered the teaching profession at age 30 or younger (87%) and worked two or more unpaid overtime hours per day (67%). The dependent variable was mental health measured through the General Health Questionnaire (GHQ-12). The independent variables were sociodemographic, teacher-related, and work conditions. The internal structure of the mental health construct was evaluated using the Rasch model. Crude odds ratios (cORs) and adjusted odds ratios (aORs) were estimated using logistic regression models. A high rate of poor mental health was identified in teachers (58%). The variables associated with poor mental health were working in a private-subsidized school (aOR = 2.89; 95% CI: 1.16-7.22), working two or more unpaid overtime hours (aOR = 2.25; 95% CI: 1.11-4.59), and being absent due to sickness (aOR = 3.82; 95% CI: 1.53-9.58). These results provide evidence suggesting the need for actions to improve the working conditions of teachers who telework in order to improve their mental health, and thus have a positive impact on the entire educational community.

Evaluación psicométrica de la escala de depresión de Yesavage en adultos mayores latinoamericanos: Estudios SABE y CRELES / Psychometric evaluation of the abbreviated scale of Yesavage depression in older adults in several cities in Latin America: Studies SABE and CRELES

Resumen Con el cambio en los patrones demográficos y las mejoras en los sistemas de salud, se espera un aumento de la población adulta mayor en el mundo y especialmente en América Latina. Esto genera un aumento en la prevalencia de enfermedades crónicas y degenerativas; una de ellas es la depresión. La depresión supone costos sociales y financieros que pueden causar trastornos a la salud y a la vida cotidiana de quien la padece y de quienes están alrededor, ya que conduce a una morbilidad y mortalidad altas. El presente estudio pretende proporcionar más evidencia psicométrica sobre la idoneidad dela Escala corta de Yessavage (GDS-15) como instrumento para identificar síntomas depresivos en varias poblaciones de adultos mayores, sin patologías específicas, de diferentes países de Latinoamérica. Se utilizaron los datos de los estudios de la Encuesta sobre Salud, Bienestar y Envejecimiento en América Latina y el Caribe (SABE) y Costa Rica, y el Estudio de Longevidad y Envejecimiento Saludable (CRELES). Se hizo uso de la teoría clásica de los tests y un modelo de Rasch. Se encontró que la escala presenta buenos indicadores de consistencia interna con Alphas de Cronbach superiores a .8 en la mayoría de los países. Cuando se evalúa con el modelo de Rasch se identifican varios ítems que no ajustan al modelo, lo que podría relacionarse con los contextos culturales o al hecho de ser población general, por lo que se sugiere que se evalúe el efecto de factores sociales, demográficos, culturales, educativos, roles de género y red de apoyo social en un modelo multinivel.

Abstract Changes in demographic patterns, as well as improvements in health systems, increase the elderly population in the world and especially in Latin America. These processes increase the prevalence of chronic and degenerative diseases such as depression. Depression involves social and financial costs that can cause disorders to the health and daily life of those who suffer from it and those around them, such as high morbidity and mortality. This study uses classical test theory and Rasch model to seek for psychometric evidence to support the suitability of Yesavage's short-scale questionnaire (GDS-15) as a suitable instrument to identify depressive symptoms in general older adult populations in Latin America. The unidimensionality of the scale in each country was validated by performing a factorial analysis of principal components with a tetrachoric correlation matrix. Cronbach's Alpha was also calculated as an indicator of the internal validity of the scale and in order to provide the values of this indicator and compare it with other studies. Using a Rasch model, this study evaluated whether there are items that present difficulties in being answered or, conversely, that do not contribute to the measurement of depression. The Rasch analysis is based on a mathematical model that describes the relationship between the probability of a correct response to an item and the difference between the ability of the respondent. This model allows the joint measurement of people and items in the same construct. By doing this, a person's interpretation of scores is richer than just ranking from percentiles. The Survey on Health, Well-Being, and Aging in Latin America and the Caribbean (Project SABE) was used, a cross-sectional study that examines health conditions and functional limitations of persons aged 60 and older in the countries of Argentina, Barbados, Brazil, Chile, Cuba, Mexico, and Uruguay. This study also used the Costa Rican Longevity and Healthy Aging Study (CRELES), a set of nationally representative longitudinal surveys of health and life course experiences of older Costa Ricans. The scale shows good internal consistency. Cronbach's Alpha was 0.8 and more in most countries. Nevertheless, the Rasch model identified some items that do not fit the model. These items are: "Have you dropped or doing less of many of your activities and interests?", "Were you afraid that something bad was going to happened to you?", "Did you prefer to stay at home instead of going out and doing new things?", "Did you feel you have more problems with your memory that other people your age?", "Did you feel full of energy?", "Did you think that most people were better off than you?". It is important to mention that these items also present drafting problems. In the case of the item "Did you prefer to stay at home instead of going out and doing things?", it can be thought that in the case of some Latin American countries, the preference for staying at home could be more related to the social and political context in which you live with depression. On the other hand, these results also invite us to think about the existence of various dimensions on this scale. Lack of fit is related to cultural contexts or to the fact that the data refers to a general population. Social, demographic, cultural, educational factors, gender roles, and social support networks could be evaluated in a multilevel model.

Measurement properties of the Boston Carpal Tunnel Questionnaire in subjects with neurophysiological confirmation of carpal tunnel syndrome: a Rasch analysis perspective.

PURPOSE: To perform a comprehensive psychometric analysis of the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) by means of factor and Rasch analyses in subjects with neurophysiologic confirmation of carpal tunnel syndrome (CTS). Relationship between clinical severity assessed with the log-linear version of the BCTQ and neurophysiologic severity assessed with nerve conduction studies was further examined. METHODS: Five hundred and twenty-eight individuals completed the questionnaire. Confirmatory and exploratory factor analyses were used to determine the latent structure of the BCTQ. Through Rasch methodology, a log-linear version was proposed given the latent structure of the questionnaire. Linear relationship between the proposed questionnaire and neurophysiologic findings was established. RESULTS: The BCTQ underlying structure comprises, at least, three factors that may be represented by Functionality, Paresthesia and Pain domains. Two log-linear subscales may be proposed: subscale 1 comprised of the Functionality factor and subscale 2 which incorporates the Paresthesia and Pain factors under a bifactor solution. Neurophysiologic and clinical severity classification system displays a very weak linear correlation. CONCLUSION: A log-linear version of the BCTQ, useful as an outcome tool in clinical and trial settings, is proposed. Neurophysiological data lack the ability to resemble changes in clinical status of individuals with CTS.

Exploring the Factor Structure of Environmental Attitudes Measure in a Sample of Indonesian College Students / Exploración de la estructura factorial de la Medida de Actitudes Ambientales en una muestra de estudiantes universitarios indonesios

Resumen El propósito de este estudio fue validar y evaluar la estructura factorial del instrumento de Medición de Actitudes hacia el Medio Ambiente mediante el análisis factorial y el modelo de Rasch politómico multidimensional. Participaron 595 estudiantes universitarios indonesios (293 hombres y 302 mujeres) con un rango de edad de 18-24 (edad media = 21,01, SD = 1,65). Los 22 ítems de la Medida de Actitudes Ambientales se administraron mediante encuestas en línea. Este estudio genera una estructura factorial tridimensional de actitudes ambientales en las muestras universitarias de Indonesia y respalda la base teórica de la escala original. Los resultados del análisis multidimensional del modelo politómico de Rasch muestran que las características psicométricas de este instrumento son excelentes y tienen una alta confiabilidad de separación, tanto por ítems como por persona. Los hallazgos de este estudio se pueden utilizar en investigaciones futuras para examinar la interrelación de las actitudes ambientales con otras variables en la muestra de Indonesia. También se discuten las limitaciones de este estudio.

Abstract The purpose of this study was to validate and evaluate the factor structure of the instrument for measuring attitudes towards the environment using factor analysis and multidimensional polytomous Rasch model. Participants in this study were 595 Indonesian university students (293 male and 302 female) with an age range of 18-24 (mean age = 21.01, SD = 1.65). The 22-items of Environmental Attitudes Measure were administered using online survey systems. This study generates a three-dimensional factor structure of environmental attitudes in the Indonesian college samples and supports the original scale's theoretical basis. The results of the multidimensional analysis of the polytomous Rasch model show that the psychometric characteristics of this instrument are excellent and have high separation reliability, both for items and person. The findings of this study can be used in future research to examine the interrelationship of environmental attitudes with other variables in the Indonesian sample. Limitations of this study are also discussed.

Creating an objective measurement for the Enem: an analysis using the Rasch Model / Criando uma medida verdadeira para o Enem: uma análise pelo Modelo Rasch / Creando una verdadera medida para Enem: un análisis por el Modelo Rasch

In the 1930s, a group of scientists argued that the empirical concatenation of observable elements was not possible in the human and social sciences and was, thus, not feasible to obtain objective measurements similar to those found in physics. To address this issue, mathematical theories that do not require concatenation were proposed in the 1960s, including the Additive Conjoint Measurement Theory (ACMT). In the same decade, George Rasch developed the simple logistic model for dichotomous data as a probabilistic operationalization of the ACMT. This study investigates the possibility of developing a fundamental measure for the National Exam of Upper Secondary Education (ENEM) that applies Rasch's model to students' performance on the 2011 ENEM exam. The results indicate an adequate model fit, demonstrating the viability of a fundamental measure using ENEM data. Implications are discussed.

Nos anos 1930, um grupo de cientistas argumentou que a concatenação empírica de elementos observáveis não seria possível nas Ciências Humanas e Sociais e por isso era inviável obter medidas verdadeiras nesses campos do conhecimento científico. Para lidar com este problema, foram propostas teorias matemáticas nas quais a concatenação empírica não seria necessária, como a Teoria de Medidas Aditivas Conjuntas (TMAC). No mesmo período, George Rasch desenvolveu o modelo logístico simples para dados dicotômicos, uma operacionalização probabilística da TMAC que viabiliza a análise empírica de pressupostos da medida verdadeira. Em nosso estudo, investigamos o desenvolvimento de uma medida verdadeira para o Exame Nacional do Ensino Médio (ENEM), aplicando o modelo logístico simples em dados referentes à performance dos participantes da edição de 2011 do ENEM. Os resultados indicaram um ajuste adequado do modelo, apontando para a viabilidade da construção de uma medida verdadeira para o ENEM. Implicações são discutidas.

En los años 1930, un grupo de científicos argumentó que la concatenación empírica de elementos observables no sería posible en Ciencias Humanas y Sociales y por consiguiente sería inviable obtener medidas verdaderas similares a las de Física. Para abordar este problema, a partir de los años 1960 se proponían teorías en las cuales la concatenación empírica no es necesaria, como la Teoría de Medidas Aditivas Conjuntas (TMAC). Al mismo período, George Rasch desarrolló el modelo logístico simple para datos dicotómicos, una operacionalización probabilista de la TMAC. Este estudio investigó la posibilidad de desarrollar una medida verdadera para el Examen Nacional de la Secundaria Superior (ENEM), aplicando el modelo logístico simple en los datos referentes a la performance de los participantes en la prueba de 2011 del ENEM. Los resultados indicaron adecuado ajuste del modelo, asi como la viabilidad de una medida verdadera para el ENEM. Implicaciones son discutidas.

Fear of COVID-19 Scale (FCV-19S) across countries: Measurement invariance issues.

AIM: The threats of novel coronavirus disease 2019 (COVID-19) have caused fears worldwide. The Fear of COVID-19 Scale (FCV-19S) was recently developed to assess the fear of COVID-19. Although many studies found that the FCV-19S is psychometrically sound, it is unclear whether the FCV-19S is invariant across countries. The present study aimed to examine the measurement invariance of the FCV-19S across eleven countries. DESIGN: Cross-sectional study. METHODS: Using data collected from prior research on Bangladesh (N = 8,550), United Kingdom (N = 344), Brazil (N = 1,843), Taiwan (N = 539), Italy (N = 249), New Zealand (N = 317), Iran (N = 717), Cuba (N = 772), Pakistan (N = 937), Japan (N = 1,079) and France (N = 316), comprising a total 15,663 participants, the present study used the multigroup confirmatory factor analysis (CFA) and Rasch differential item functioning (DIF) to examine the measurement invariance of the FCV-19S across country, gender and age (children aged below 18 years, young to middle-aged adults aged between 18 and 60 years, and older people aged above 60 years). RESULTS: The unidimensional structure of the FCV-19S was confirmed. Multigroup CFA showed that FCV-19S was partially invariant across country and fully invariant across gender and age. DIF findings were consistent with the findings from multigroup CFA. Many DIF items were displayed for country, few DIF items were displayed for age, and no DIF items were displayed for gender. CONCLUSION: Based on the results of the present study, the FCV-19S is a good psychometric instrument to assess fear of COVID-19 during the pandemic period. Moreover, the use of FCV-19S is supported in at least ten countries with satisfactory psychometric properties.

Batería de evaluación de cognición social en psicología forense: adaptación y validación / Bateria de avaliação para cognição social em psicologia forense: adaptação e validação / Assessment battery for social cognition in forensic psychology: adaptation and validation

El objetivo del estudio fue adaptar y validar una batería de instrumentos para evaluar subdominios de la cognición social con población forense en Colombia y México a partir de una selección de instrumentos utilizados en neuropsicología clínica. Se revisó la pertinencia de los subdominios que componen la cognición social como evidencia de validez de contenido mediante la evaluación de diferentes expertos en psicología forense, neuropsicología y medición y evaluación; utilizando el método ANGOFF modificado y un análisis de confiabilidad según el modelo Rasch y el coeficiente Alfa de Cronbach. Posteriormente fue sometido a pilotaje con 20 personas condenadas en cárceles colombianas y mexicanas con privación de libertad. Se encontraron calibraciones INFIT 1.17 y 1.04, OUTFIT 1.08 y 1.18, con índices de separación de 2.66 y 1.63, y fiabilidad de .88 en colombianos y .73 en mexicanos; estos datos proporcionaron evidencias de validez de la batería adaptada.

The aim of the study was to adapt and validate a battery for the evaluation of subdomains of social cognition with the forensic population in Colombia and Mexico from a selection of instruments used in clinical neuropsychology. We reviewed the relevance of the subdomains that compose social cognition as evidence of content validity through the assessment of different psychologists, experts in forensic psychology, neuropsychology and measurement and evaluation, using the modified ANGOFF method and a reliability analysis according to the Rasch model and Cronbach's Alpha coefficient. Subsequently, a pilot study was performed with 20 people deprived of liberty in Colombian and Mexican prisons. INFIT calibrations of 1.17 and 1.04, and OUTFIT calibrations of 1.08 and 1.18, with separation rates of 2.66 and 1.63, and reliability of .88 and .73 were found in Colombians and Mexicans respectively; these data provide evidence of the validity of the adapted battery.

Psychometric Properties of the Spanish Version of the Goal Orientation Scales in Ecuadorian Undergraduate Students.

The present study aims to analyze the psychometric properties of the Goal orientation Scales (GOS; Skaalvik, 1997) in a sample of 2,170 Ecuadorian undergraduate students (M = 21. 97, SD = 3.61; 61.6% female). The Exploratory Factor Analysis and Confirmatory Factor Analysis supported the four-factor structure of the GOS, and the scale exhibited an adequate factorial invariance for gender. The multidimensional Rasch analysis revealed that one item showed misfit, and the distribution of items did not correspond well with the levels of achievement goals. The current research addresses a formal gap related to the validation of the GOS in a Latin American country and provides advanced psychometric information to further improve the scale for its application to Spanish-speaking samples.
