RESUMO

El estudio examina las características psicométricas de una escala que mide la percepción sobre el teletrabajo femenino en la población chilena en situación de confinamiento familiar, construida durante la pandemia por COVID-19. El cuestionario explora la interacción entre los ámbitos del trabajo y la familia, centrándose específicamente en la salud mental, las actitudes hacia el teletrabajo femenino, las dinámicas familiares relacionadas con el teletrabajo femenino y las dinámicas laborales en el contexto del teletrabajo femenino durante la pandemia. Los resultados indican una fuerte coherencia interna tanto para la escala global como para sus cuatro dimensiones diferenciadas: Salud Mental, ámbito laboral, teletrabajo femenino y ámbito familiar. El análisis factorial exploratorio (AFE) revela índices de ajuste favorables gl = 17; p<0.183; x 2 /gl = 22.211; CFI = 0.995; NNFI = 0.983; RMSEA = 0.052 para los 12 ítems en las cuatro dimensiones, alineándose bien con la estructura teórica respaldando los fundamentos del constructo balance trabajo/familia.


The study examines the psychometric characteristics of a scale that measures the perception of female teleworking in the Chilean population in a situation of family confinement, built during the COVID-19 pandemic. The questionnaire explores the interaction between the spheres of work and family, specifically focusing on mental health, attitudes towards female teleworking, family dynamics related to female teleworking, and work dynamics in the context of female teleworking during the pandemic. The results indicate strong internal coherence both for the global scale and for its four differentiated dimensions: Mental Health, work environment, female teleworking and family environment. The exploratory factor analysis (EFA) reveals favorable adjustment indices df = 17; p<0.183; χ 2 /df = 22.211; CFI = 0.995; NNFI = 0.983; RMSEA = 0.052 for the 12 items in the four dimensions, aligning well with the theoretical structure supporting the foundations of the work/family balance construct.


O estudo examina as características psicométricas de uma escala que mede as percepções do teletrabalho feminino na população chilena em confinamento familiar, construída durante a pandemia da COVID-19. O questionário explora a interação entre os domínios do trabalho e da família, concentrando-se especificamente na saúde mental, nas atitudes em relação ao teletrabalho feminino, na dinâmica familiar relacionada ao teletrabalho feminino e na dinâmica do trabalho no contexto do teletrabalho feminino durante a pandemia. Os resultados indicam uma forte consistência interna tanto para a escala geral quanto para suas quatro dimensões distintas: saúde mental, ambiente de trabalho, teletrabalho feminino e ambiente familiar. A análise fatorial exploratória (AFE) revela índices de ajuste favoráveis gl = 17; p<0,183; χ 2 /gl = 22,211; CFI = 0,995; NNFI = 0,983; RMSEA = 0,052 para os 12 itens nas quatro dimensões, alinhando-se bem com a estrutura teórica que sustenta os fundamentos do conceito de equilíbrio entre trabalho e família.

RESUMO

Introduction: This study aimed to investigate the Self-Regulated Learning behaviors of advanced Brazilian and Portuguese musicians and how these processes vary in terms of gender, nationality, musical instrument, quantity of practice, expertise, and professional experience. Methods: 300 participants fully completed the 22-item questionnaire "Attitudes in music practice". The sample comprised of 54.3% males, 44.0% females, and 1% non-binary; 0.7% did not respond. 68.0% (n = 204) were Brazilian, and 32.0% (n = 96) were Portuguese. The mean age was 32.70 years old (SD = 11.261), the mode was 22 years old, with a range of 18 to 66 years. Data analysis procedure included exploratory factor analysis, internal consistency, independent sample t test, analysis of variance (ANOVA), and chi-square tests. Results: Exploratory Factor Analysis generated three factors: Practice Organization, Personal Resources, and External Resources. The results report there are no differences in SRL scores in terms of gender, nationality, and musical instrument. However, One-way ANOVA test results convey differences in SRL scores and the quantity of practice and expertise with those musicians who reported practicing for longer periods scoring more highly than participants who declared spending less time on daily practice. Discussion: The results for the expertise variables suggest that more experienced and older musicians scored higher in Personal Resources and lower in External Resources indicating that, as musicians gain in experience, their metacognitive processes become more evident than the social factors of their performance.

RESUMO

Landslides are one of the natural phenomena with more negative impacts on landscape, natural resources, and human health worldwide. Andean geomorphology, urbanization, poverty, and inequality make it more vulnerable to landslides. This research focuses on understanding explanatory landslide factors and promoting quantitative susceptibility mapping. Both tasks supply valuable knowledge for the Andean region, focusing on territorial planning and risk management support. This work addresses the following questions using the province of Azuay-Ecuador as a study area: (i) How do EFA and LR assess the significance of landslide occurrence factors? (ii) Which are the most significant landslide occurrence factors for susceptibility analysis in an Andean context? (iii) What is the landslide susceptibility map for the study area? The methodological framework uses quantitative techniques to describe landslide behavior. EFA and LR models are based on a historical inventory of 665 records. Both identified NDVI, NDWI, altitude, fault density, road density, and PC2 as the most significant factors. The latter factor represents the standard deviation, maximum value of precipitation, and rainfall in the wet season (January, February, and March). The EFA model was built from 7 latent factors, which explained 55% of the accumulated variance, with a medium item complexity of 1.5, a RMSR of 0.02, and a TLI of 0.89. This technique also identified TWI, fault distance, plane curvature, and road distance as important factors. LR's model, with AIC of 964.63, residual deviance of 924.63, AUC of 0.92, accuracy of 0.84, and Kappa of 0.68, also shows statistical significance for slope, roads density, geology, and land cover factors. This research encompasses a time-series analysis of NDVI, NDWI, and precipitation, including vegetation and weather dynamism for landslide occurrence. Finally, this methodological framework replaces traditional qualitative models based on expert knowledge, for quantitative approaches for the study area and the Andean region.

RESUMO

Risk perception is a concept related to the decision-making process and allows people to perceive the hazards surrounding the context and choose the best preventive methods to avoid them. The COVID-19 pandemic was a remarkable era in which people had to adopt protective methods, such as social isolation, to reduce the possibility of being contaminated by the virus. This study covers the development, psychometric properties, and norms of a scale to assess Risk Perception regarding COVID-19 and Social Isolation. The analysis suggested good expert agreement regarding the adequacy of the scale content and items and factor analysis suggested two factors, called the emotional and cognitive domains. The composite reliability suggested the internal consistency of the scale and its factors. All the results of this study suggest that this scale presents evidence of construct validity, constituting a reliable instrument. This new instrument may be used to evaluate risk perception related to COVID-19 and Social Isolation.

RESUMO

Bone mass and quality decline with age, and can culminate in osteoporosis and increased fracture risk. This investigation modeled associations between bone and physical, dietary, and metabolic factors in a group of 200 pre-frail/frail older adults using factor analysis and structural equation modeling (SEM). Exploratory (EFA) and confirmatory factor analysis (CFA) were conducted to compose factors and to assess their robustness. SEM was used to quantify associations between bone and the other factors. Factors arising from EFA and CFA were: bone (whole body, lumbar and femur bone mineral density, and trabecular bone score; good fit), body composition - lean (lean mass, body mass, vastus lateralis, and femoral cross-sectional area; good fit), body composition - fat (total fat mass, gynoid, android, and visceral fat; acceptable fit), strength (bench and leg press, handgrip, and knee extension peak torque; good fit), dietary intake (kilocalories, carbohydrate, protein, and fat; acceptable fit), and metabolic status (cortisol, insulin-like growth factor 1 (IGF-1), growth hormone (GH), and free testosterone; poor fit). SEM using isolated factors showed that body composition (lean) (ß = 0.66, P < 0.001), body composition (fat) (ß = 0.36, P < 0.001), and strength (ß = 0.74, P < 0.001) positively associated with bone. Dietary intake relative to body mass negatively associated with bone (ß = -0.28, P = 0.001), whereas in absolute terms, it showed no association (ß = 0.01, P = 0.911). In a multivariable model, only strength (ß = 0.38, P = 0.023) and body composition (lean) (ß = 0.34, P = 0.045) associated with bone. Resistance training programs that focus on improving lean mass and strength in older individuals may benefit bone in this population.NEW & NOTEWORTHY We used factor analysis and structural equation modeling, which are rarely used in nutrition or exercise science, but constitute powerful tools that may overcome limitations of traditional analyses, combining individual related variables into factors or constructs of interest. Our investigation represents a starting point on this progressive pathway, providing useful insight and a working model for researchers and practitioners who wish to tackle complex problems such as the multifactorial causes of bone loss in older adults.

RESUMO

Resumen Los elogios son definidos como devoluciones positivas otorgadas a personas sobre sus atributos, sobre la realización de una tarea o sobre los objetos o productos realizados. Los distintos tipos de elogios que los cuidadores primarios o padres utilicen con los infantes cuando ellos realicen una actividad impactarán en su desarrollo, en las creencias o percepción de sí mismos o de los modos de aprender, y en la motivación hacia esas tareas que la niña o el niño realice. Estos modos de elogiar no han sido estudiados en la Argentina y no existen instrumentos estandarizados psicométricos para evaluarlos. Por esto, el objetivo de este estudio fue la creación y validación de una técnica de auto-reporte para evaluar los elogios que otorgan los cuidadores a infantes de 0 a 3 años. Los participantes que conformaron la muestra (. = 128) fueron reclutados por medio de internet y completaron un cuestionario de escala Likert de aproximadamente cinco minutos de duración. A partir del análisis factorial exploratorio, se ajustó la técnica y se agruparon las preguntas del cuestionario en tres dimensiones: elogios de persona, proceso y producto. Esto permitiría hacer una evaluación breve y sencilla de los elogios utilizados, lo que en un futuro aportaría a intervenciones o estudios que pretendan favorecer elogios que beneficien un desarrollo adaptativo de los infantes. Sin embargo, aún es necesario un futuro estudio que indague cambios en la técnica con un mayor tamaño muestral para la realización de una validación más exhaustiva.


Abstract Praise is defined as positive feedback given to people about their attributes, their performance, the objects or products made by them. The different types of praise that primary caregivers or parents use with infants when they carry out an activity will impact on their development, beliefs or perception of themselves or types of learning, and motivation toward the tasks that the children perform. One type of praise is the praise directed towards an individual, which compliments their own attributes such as her intelligence. Another one is the product praise, which is directed towards the final objects or actions that the infant performs, such as a drawing or physical activities. Finally, a praise directed at the process aims to congratulate the infant during the task as a process, either for making an effort or for the strategies that they use to achieve something. This last kind of praise favors perseverance in the face of new tasks to a greater extent, while praise directed at the person could generate more frustration when the infant experiences failure. Therefore, the way caregivers interact with infants is relevant, since it modulates motivation and the development of different skills. For this reason, the main objective of this study was the creation and validation of a self-report technique to assess the praise that Argentinean caregivers give to infants from 0 to 3 years of age. The sample was made up of 128 primary caregivers (. = 128) who were recruited through the internet. They completed a Likert scale questionnaire of approximately 5 minutes of duration. The data was collected during preventive social isolation due to COVID-19. This could lead to changes in parental behavior, while it also provides ecological value for understanding the ways to praise in this context, where caregivers spend a lot of time with infants; however, it would be important to conduct future research outside of this context. An exploratory factor analysis was performed, which led to an adjustment in the technique by eliminating four items in order to improve the psychometric characteristics of the instrument. By this analysis, the formation of the three dimensions was justified by the types of praise: person, process, and product praise.The final instrument consisted of 13 phrases that represent possible compliments used by caregivers. Participants indicated how often they usually use those compliments on a scale from 1 (never) to 5 (very often). The items are divided by types of praise: six were assigned to the product dimension, three to the process dimension and four to the person dimension. The internal consistencies of the dimensions were process (α = .91), product (α = .74) and person (α = .73). This self-report technique for primary caregivers of infants would allow a short and simple evaluation of the praise used. In future research, this technique would allow an assessment of praise for the realization of studies that seek to expand the knowledge about how they affect child development. Likewise, it would contribute to the development of interventions with caregivers aimed to promote praise that benefits an adaptive development of infants. However, more studies are needed to investigate possible changes in the inventory, such as the inclusion of neutral praise or negative feedback. Furthermore, a larger sample size would be necessary to carry out a more exhaustive validation, performing a confirmatory factor analysis, convergent variance and factor invariance.

RESUMO

Daily commuting characteristics were highly affected by the COVID-19 pandemic, since restriction of the movement of people was one of the main preventive measures adopted. Understanding of the effects that the pandemic had on mobility is essential to help in mitigating the problems arising from this crisis, while also providing an opportunity for the implementation of sustainable policies in the post-pandemic period. Therefore, the aim of this study was to identify the impacts of the pandemic on the profile of travel behavior and mobility preferences in Brazil, using a case study of cities located in the state of Rio Grande do Sul. The data obtained from an online survey were modeled using exploratory factor analysis, resulting in the extraction of 15 main factors that explain behavioral changes in mobility due to the effects of the pandemic, as well as future perspectives. In the pandemic period, the use of private vehicles grew as the main mode of transport to the principal activity. Conversely, the use of public transport decreased drastically, due to compulsory measures taken by the health authorities to prevent the spread of the new virus. There was also greater receptivity to the adoption of active mobility, especially the bicycle, although it is necessary to provide better conditions for use of this transport mode. The findings support the development of public policies to reduce urban mobility problems and to provide guidelines for sustainable planning in the post-pandemic period.

RESUMO

Abstract Introduction: Assessing professionalism represents a challenge for medical educators given the nature of its construct, which comprises diverse values, beliefs, and principles. Understanding this psychological phenomenon is fundamental for reaching the goals in medical education. Objective: This study aimed to translate into Brazilian Portuguese and to validate the Penn State College of Medicine Professionalism Questionnaire. Method: The questionnaire was translated, and cross-culturally adapted into Brazilian Portuguese using data from 249 medical students. An exploratory factor analysis was conducted, using a polychoric matrix and the Robust Diagonally Weighted Least Squares method of extraction. The following model adequacy indexes and criteria were used: Root Mean Square Error of Approximation (RMSEA) adjustment indexes <0.08, Comparative Fit Index (CFI) and Tucker-Lewis Index (TLI) >0.90. Result: The exploratory factor analysis obtained a KMO = 0.920, and a significant Bartlett's test of sphericity (2719.0, gl = 630; P <0.001). The parallel analysis yielded a three-factor solution, which showed adequate levels of reliability: Professional-Patient Relationship, Professional Development and Ethical Commitment. The three-factor solution was the best one found to represent the data. Conclusion: The questionnaire evidenced good psychometric properties and appropriateness to evaluate medical students' professionalism, contributing to reach more desirable ethical standards in medical education.

RESUMO

BACKGROUND: One of the most significant human qualities is the ability to develop, implement, and flexibly maintain planned behaviour in order to achieve one's goals. Self-regulation has become a relatively well-researched area in the field of psychology and pedagogy. However, empirically valid and reliable instrument is still missing across European context. The primary goal of this research was to analyze the psychometric properties of the Czech version of the Self-Regulation Questionnaire (SRQ-CZ) among adult learners from Poland, Serbia, Slovakia, and the Czech Republic. OBJECTIVE: The aim of the present study was to examine the factor structure and psychometric properties of the SRQ-CZ validated in the Czech educational context in a multi-cultural sample. METHODS: A total of 1711 adult learners from European countries including Poland, Serbia, Slovakia, and the Czech Republic completed the SRQ-CZ. The first step to reviewing the validity of the SRQ-CZ included testing face validity. Furthermore, exploratory factor analysis (EFA) was performed on half the sample and confirmatory factor analysis (CFA) on the other half. Measurement invariance was conducted across gender, age, and country followed by the evaluation of the reliability of the final instrument. RESULTS: EFA showed that a three-factor structure best fit the data. The originally proposed Impulse Control and Self-Direction are merged into one distinct factor, while Decision Making and Goal Orientation comprise the other two. Goodness-of-fit statistics yielded from CFA showed a good fit for the model, introducing a reliable and measurement invariant instrument. CONCLUSION: The present study used a diverse multi-cultural sample to explore the factorial structure and psychometric properties of the SRQ-CZ. A three-factor model was obtained as the result of the exploratory and confirmatory factor analyses. Further analysis aiming at measurement invariance, comparing the sample according to gender, age, and country, led to satisfactory results. The only exception was a lack of model fit in the case of Serbia. Although further psychometric evaluation of the SRQ-CZ is still needed, the presented results constitute significant findings, confirming instrument validity and utility as a measure of generalized self-regulation capacity across adult learners in European educational context.

RESUMO

The possibility of facing an epidemic or pandemic resulting in mandatory isolation or quarantine has become a relevant construct for comparing and evaluating coping strategies under such conditions. The objective of this research was to develop and analyze the psychometric properties of a scale to assess quarantine coping strategies (Q-COPE). This was an instrumental study and 1110 Peruvian adults (M = 26.9 years; SD = 9.77) participated in the context of social isolation. For the construction of the scale, qualitative and quantitative procedures were followed. The internal structure was evaluated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The content analysis by expert judges supports the representativeness of the items related to the construct. EFA and CFA allowed the establishment of five factors: Emotional regulation, Information, Accommodation, Social support, and Altruism. The first-order model presents adequate goodness-of-fit indices: χ2 = 489.048, df = 220, χ2/df = 2.223, SRMR = 0.025, CFI = 0.969, TLI = 0.965, RMSEA = 0.047. Likewise, the second order model presented similar values: χ2 = 499.674, df = 225, χ2/df = 2.221, SRMR = 0.026, CFI = 0.969, TLI = 0.965, RMSEA = 0.047. The 23-item version was consistent with the proposed theory, obtained adequate fit indices and acceptable factor loadings (>0.70), and presented good internal consistency indexes evaluated by Cronbach's α, ordinal α, omega (ω), and H coefficient. It is concluded that the Q-COPE scale presents good psychometric properties that justify its use in an adult population and allows the assessment of the coping strategies that people use in the face of a quarantine situation.

RESUMO

Resumen El estudio acerca de las causas de la pobreza ha sido influenciado por la teoría de la atribución, lo que permitió identificar los juicios predominantes que las personas establecen sobre tales causas. Los estudios locales sobre las atribuciones causales de la pobreza son escasos y no se ha identificado ninguno referido a las causas de la pobreza infantil, a pesar de las altas tasas de su incidencia en el país. Así, el presente estudio propone evaluar las atribuciones causales de la pobreza general e infantil por parte de adultos de Argentina, empleando dos cuestionarios (uno sobre las causas de la pobreza en general y el otro sobre la pobreza infantil en particular) implementados de manera virtual. La muestra incluyó a 1 659 participantes (17 a 90 años), quienes debieron indicar la importancia de cada ítem como causa de la pobreza en una escala tipo Likert de cinco puntos. En cuanto al cuestionario sobre las causas de la pobreza general, el análisis exploratorio permitió identificar una estructura de tres factores -similar a la identificada en otros estudios: individualista, estructurales y fatalistas-, la cual no fue verificada en el análisis confirmatorio. Con respecto al cuestionario sobre las causas de la pobreza infantil, se identificó y se confirmó un modelo de dos factores (que podrían estar relacionados con atribuciones estructurales y familiares) que representa una nueva evidencia en el campo. Los resultados sugieren diferencias en las atribuciones de las causas de pobreza general e infantil, cuyos posibles mecanismos (e. g., modulación por parte de factores individuales, contextuales y culturales) deberían explorarse en estudios futuros.


Abstract In the last decades, different studies have addressed the perspectives of people regarding the causes of poverty, as they could play a fundamental role in the development of individual and social attitudes, beliefs and expectations towards people living in such a condition, and in the strategies implemented to solve related problems and issues. In addition, many of those studies have investigated the causes of poverty using the theoretical model proposed by Feagin (1972), which suggests three broad explanations: (1) individualistic (i. e., causal attribution is placed on the poor themselves); (2) structural (i. e., poverty is due to external social and economic factors); and (3) fatalistic (i. e., poverty is attributed to factors such as bad luck). Most of those studies have been carried out considering the causes of poverty in general, which means that there is very little research aimed at studying specifically the causes of child poverty. Given the high incidence of poverty in Argentina the knowledge about such perspectives is of interest for multiple basic and applied purposes. In this sense, the present study proposed to evaluate the attributions of the causes of poverty in general and child poverty in particular, by adults from Argentina, through two virtual questionnaires (one asking for the causes of poverty in general, and the other for the causes of child poverty). The sample included responses from 1 659 citizens of Argentina from 17 to 90 years old (M = 45.72, SD = 16.94). The questionnaires included 32 items aimed at evaluating the attribution of causes of general poverty, and 30 items related to child poverty. Participants were asked to indicate the importance of each item as a cause of poverty on a five-point Likert-type scale (1 = does not matter; 5 = extremely important). Exploratory and confirmatory factor analyses were implemented (separately from the general and child questionnaires) and retained items with factor loadings at .40 or above. In addition, for the general questionnaire, a second approach was implemented to analyze if the factorial structure supported by different studies in the literature was confirmed in this sample. For such a purpose, confirmatory factor analyses were implemented. Regarding the questionnaire for the causes of general poverty, the exploratory analysis allowed identifying a three-factor structure (as in the case of other studies) (RMSEA = .071; CFI = .94; TLI = .93), which was not verified in the confirmatory analysis (RMSEA = .103; CFI = .88; TLI = .86). On the other hand, the results of the second approach suggest the confirmation of the two-factor model proposed in the literature (RMSEA = .083; CFI = .96; TLI = .95). This pattern of results suggests sensitivity to the inclusion of new items. In this sense, in future studies it would be important to invest efforts in determining new items from consultations with experts and other social actors. Regarding the questionnaire for the causes of poverty in children, two-factor model was identified and confirmed (RMSEA = .074; CFI = .94; TLI = .93), which is a new piece of evidence in the field, suggesting variability in the attribution of causes of poverty according to the considered age group, and whose potential mechanisms in comparison with the studies on adult poverty should be explored in future research (e. g., individual, contextual and cultural factors). Finally, this study confirms that having valid and reliable instruments to explore the causal attributions of general and child poverty would be important to advance in the understanding of poverty as a complex and multidimensional phenomenon.

RESUMO

This is one of a series of monographs on research design and analysis. The purpose of this article is to describe a set of statistical procedures or techniques used to develop and test structural models that characterize the relationships and interrelationships between a group of concepts and variables. These procedures include multiple regression, exploratory and confirmatory factor analysis, path analysis, and structural equation modeling. The article describes the purpose of each of these procedures and how they relate to and build on one another. It also covers the different types of variables examined, including the distinction between endogenous, exogenous, and mediating variables, along with the distinction between measured and unmeasured (or latent) variables. Each procedure results in a set of statistical estimates, and the article presents the interpretation of these estimates, including regression coefficients (standardized and unstandardized), path coefficients, factor loadings, and coefficients of determination (or R2 values). The article presents examples of how each procedure has been used in practice, along with additional resources for readers who wish to learn more.

RESUMO

Introduction: Early menarche is associated with obesity, and metabolic and mental health risks, among other diseases. Thus, it is relevant to identify modifiable risk factors of early menarche. Some nutrients and foods have been linked to pubertal timing, but how menarche relates to overall dietary patterns is unclear. Methods: The aim of this study was to analyze the association between dietary patterns and age at menarche in a prospective cohort of Chilean girls from low and middle-income families. We conducted a survival analysis of 215 girls (median = 12.7 years, IQR = 12.2-13.2) from the Growth and Obesity Cohort Study (GOCS) who had been followed prospectively since 4 years of age (2006). Age at menarche and anthropometric measurements were recorded every 6 months since 7 years of age while diet (24-hour dietary recall) was collected for 11 years. Dietary patterns were obtained from exploratory factor analysis. Accelerated Failure Time models adjusted for potential confounding variables were used to study the association between dietary patterns and age at menarche. Results: Girls' median age at menarche was 12.7 years. Three dietary patterns were identified: "Breakfast/Light Dinner," "Prudent" and "Snacking" which explained 19.5% of the diet variation. Girls in the lowest tertile of the "Prudent" pattern had menarche 3 months earlier than girls in the highest tertile (ß: 0.022; 95% CI: 0.003; 0.041). "Breakfast/Light Dinner" and "Snacking" patterns were not associated with age at menarche. Conclusion: Our results suggest that healthier dietary patterns during puberty might be associated with menarche timing. Nevertheless, further studies are required to confirm this result and to clarify the association between diet and puberty.

RESUMO

Objectives: To obtain evidence on the psychometric properties of the Patient Health Questionnaire - 9 (PHQ-9, one of the most extensively used tools for assessing depression) in the Brazilian older population.Method: Data on 3,356 Brazilian adults aged 60+ years living in Guarulhos, São Paulo state were used. The factor structure of the questionnaire was analysed using a factor analysis approach. The questionnaire's measurement equivalence was tested across gender, age, personal income, and education level groups. The scores were compared across groups based on the highest level of equivalence achieved. The questionnaire's internal consistency was analysed considering its factor structure.Results: A one-factor solution was identified as the most adequate factor structure, with the factor explaining 57.6% of the items' variance. The correlation of the resulting latent score with the overall raw sum score in the PHQ-9 was r = 0.96. Measurement equivalence regarding thresholds and loadings was achieved for all tested groups. On average, women, older, less educated, and poorer people had higher latent scores on the depression factor. The measure showed a good internal consistency with Revelle's omega total ωt=0.92.Conclusion: The results suggest that, among Brazilian older adults living in Guarulhos, São Paulo state, the PHQ-9 measures depressive symptomatology equivalently across different sociodemographic subgroups. Moreover, it can be scored using the raw sum of the item scores to adequately reflect different levels of depressive symptomatology.

RESUMO

El presente estudio instrumental evaluó las propiedades psicométricas del Inventario de Orientación Suicida ­ ISO-30 con 1922 adolescentes escolarizados de la ciudad de Bogotá. La validez de constructo del inventario se estableció a través de un análisis factorial confirmatorio, utilizándose el método de mínimos cuadrados generalizados (GLS), dando lugar un modelo factorial sustentable, compuesto por cinco factores, igual al inventario original. La confiabilidad del instrumento se estableció, a través del coeficiente Alfa de Cronbach, obteniéndose una confiabilidad excelente (α= .0915) y un coeficiente Omega (Ω=.742). El análisis de reactivos relativo al poder de discriminación del inventario obtuvo un 57% en las correlaciones ítem-escala total con un nivel de discriminación excelente. Se presenta evidencia respecto a la validez y confiabilidad del ISO-30 para evaluar la orientación al suicidio en adolescentes colombianos


The present instrumental study evaluated the psychometric properties of the Inventory of Suicide Orientation - ISO-30 with 1922 school adolescents from Bogotá. The construct validity of the inventory was established through confirmatory factor analysis, using the generalized least squares (GLS) technique, through which a sustainable factorial model was obtained, composed of five factors equal to the original inventory. The reliability of the instrument was established using Cronbach's Alpha coefficient with an excellent result (α= .915) and an omega coefficient (Ω=.742). The analysis of the items, relative to the discrimination power of the items, obtained 57% in item-total scale correlations with an excellent level of discrimination power. These findings prove ISO-30 to be a valid and reliable instrument for evaluating suicide orientation among Colombian adolescents.

RESUMO

Resumen Introducción: El bienestar psicológico favorece el funcionamiento de la vida personal y social. Para su evaluación, es necesario contar con instrumentos válidos y confiables que permitan decidir y valorar las acciones necesarias para promoverlo. Objetivo: Evaluar las propiedades psicométricas de la Escala de Bienestar Psicológico para Adultos (BIEPS-A) en una muestra mexicana. Método: Se aplicó la escala BIEPS-A y la Escala de Autoestima de Rosenberg (EAR) a 188 estudiantes universitarios y 94 participantes de población general. Resultados: Un análisis paralelo detectó un factor único en la escala BIEPS-A, estructurado mediante análisis factorial exploratorio (componentes principales, rotación oblicua) que retuvo 9 reactivos y explicó el 54% de la varianza. La consistencia interna fue de aceptable (α de Cronbach = .78) a elevada (alfa ordinal = .90). El análisis de curva ROC identificó un punto de corte equivalente a la mediana (ABC = .72, p < .01) y otro al percentil 75 (ABC = .80, p < .01), y ser mujer, tener entre 18 y 25 años y bajo o leve nivel de autoestima como predictores de bajo nivel de bienestar psicológico. La escala BIEPS-A mostró validez concurrente (r = .57) y predictiva con la EAR (β = .63). Discusión y conclusiones: La escala BIEPS-A es un instrumento válido y confiable para evaluar el bienestar psicológico en población mexicana; sin embargo, las diferencias respecto a su estructura original indican la necesidad de una escala de bienestar psicológico diseñada específicamente para población mexicana.


Abstract Introduction: Psychological well-being favors the functioning of personal and social life. Valid and reliable instruments are necessary for its evaluation that allow deciding and assessing the actions necessary to promote it. Objective: To evaluate the psychometric properties of the Scale of Psychological Well-being for Adults (BIEPS-A) in a Mexican sample. Methods: The BIEPS-A scale and the Rosenberg Self-Esteem Scale (RSES) were administered to 188 university students and 94 participants from the general population. Results: A parallel analysis detected a single factor in the BIEPS-A scale, structured by exploratory factor analysis (main components, oblique rotation) that retained 9 items and explained 54% of the variance. Internal consistency ranged from acceptable (Cronbach's α = .78) to high (ordinal alpha = .90). ROC curve analysis identified a cut-off point equivalent to the median (AUC = .72, p <.01) and another to the 75th percentile (AUC = .80, p <.01). The latter identified as a woman, between 18 and 25 years old with a low or slight level of self-esteem as predictors of a low level of psychological well-being. The BIEPS-A scale showed concurrent (r = .57) and predictive (β = .63) validity with the EAR. Discussion and conclusions: The BIEPS-A scale is a valid and reliable instrument to assess psychological well-being in the Mexican population. However, the differences with respect to its original structure indicate the need for a psychological well-being scale designed specifically for the Mexican population.

RESUMO

Similar interventions to stop the spread of COVID-19 led to different outcomes in Latin American countries. This study aimed to capture the multicausality of factors affecting HS-capacity that could help plan a more effective response, considering health as well as social aspects. A facilitated GMB was constructed by experts and validated with a survey from a wider population. Statistical analyses estimated the impact of the main factors to the HS-capacity and revealed the differences in its mechanisms. The results show a similar four-factor structure in all countries that includes public administration, preparedness, information, and collective self-efficacy. The factors are correlated and have mediating effects with HS-capacity; this is the base for differences among countries. HS-capacity has a strong relation with public administration in Bolivia, while in Nicaragua and Uruguay it is related through preparedness. Nicaragua lacks information as a mediation effect with HS-capacity whereas Bolivia and Uruguay have, respectively, small and large mediation effects with it. These outcomes increase the understanding of the pandemic based on country-specific context and can aid policymaking in low-and middle-income countries by including these factors in future pandemic response models.

RESUMO

A Escala de Frustração e Desconforto (efd) avalia as crenças de intolerância à frustração. Este trabalho objeti-vou: adaptar esse instrumento para o contexto brasileiro; buscar evidências de validade de conteúdo, de estrutura interna e com base na relação com variáveis externas e, por fim, verificar a relação entre os níveis de intolerância à frustração com gênero e idade dos participantes. A amostra foi composta por 293 indivíduos, com idade média de 21.6 anos (dp= 3.57). Foram aplicados a efd, o Patient Health Questionnaire-4 (phq-4) e um questionário sociodemográfico. Os resultados da análise fatorial exploratória indicaram a pertinência de so-lução fatorial composta por duas dimensões. Quanto a consistência interna, foram verificados bons índices para ambos os fatores e para a escala. Observou-se associação positiva e estatisticamente significativa entre a efd e o phq-4, atestando a validade baseada na relação com variáveis externas. Não foram identificadas diferenças estatisticamente significativas nos níveis de intolerância à frustração em razão do gênero e idade. Baseado nes-ses achados, conclui-se que a versão adaptada da efdapresentou propriedades psicométricas satisfatórias, sendo adequada para investigação da intolerância à frustração, possibilitando que pesquisadores e profis-sionais investiguem como esse construto se manifesta na população brasileira e como ele se relaciona com variáveis associadas à saúde mental


La Escala de Frustración y Malestar (efm) evalúa las creencias de intolerancia a la frustración. Este trabajo tuvo como objetivo adaptar este instrumento al contexto brasileño; buscar evidencias de validez de contenido, de estructura interna, y en función de la relación con variables externas y, finalmente, verificar la relación entre los niveles de intolerancia a la frustración con el género y la edad de los participantes. La muestra estuvo formada por 293 individuos, con una edad promedio de 21.6 años (de = 3.57). Se aplicó el efm, el Patient Health Questionnaire-4 (phq-4) y un cuestionario sociodemográfico. Los resultados del análisis factorial exploratorio indicaron la relevancia de una solución factorial compuesta por dos dimensiones. En cuanto a la consistencia interna, se encontraron buenos índices para ambos factores y para la escala. Hubo asociación positiva y estadísticamente significativa entre el efmy el phq-4, lo que da fe de la validez en función de la relación con variables externas. No se identificaron diferencias estadísticamente significativas en los niveles de intolerancia a la frustración por género y edad. Con base en estos hallazgos, se concluye que la versión adaptada del efm tuvo propiedades psicométricas satisfactorias, apta para la investigación de la intolerancia a la frustración, permitiendo a investigadores y profesionales investigar cómo este constructo se manifiesta en la población brasileña y cómo se relaciona con las variables asociadas con la salud mental


The Frustration Discomfort Scale (fds) assesses beliefs about frustration intolerance. This study aimed at adap-ting this instrument to the Brazilian context, providing evidence for content validity of internal structure, and based on the relationship with external variables. In addition, we verified the relationship of the level of frustration intolerance with the gender and age of the participants. The sample consisted of 293 individuals, with an average age of 21.6 years(SD = 3.57). The fds, the Patient Health Questionnaire-4 (phq-4), and a so-ciodemographic questionnaire were applied. The explo-ratory factor analysis results indicated the best solution to be a structure with two dimensions. Good indexes of internal confidence were found for both factors and the whole scale. A positive and statistically significant association was observed between the fds and phG-4, which attests to the validity based on its relationship to external variables. No statistically significant differen-ces of frustration tolerance were identified for gender or age. Based on these findings, we conclude that the adapted version of the fds has satisfactory psychometric properties and is suitable for investigating intolerance to frustration, enabling researchers and professionals to investigate how this construct is manifested in the Brazilian population and how it relates to variables as-sociated with mental health

RESUMO

Resumen El objetivo del estudio fue explorar la estructura factorial de la Brief Self-Control Scale (BSCS; Tangney, Baumeister y Boone, 2004) aplicada como autorreporte a una muestra de 151 participantes en Colombia (edad promedio de 8.2 años, 50.33 % niñas y 49.66 % niños) y 115 participantes en Chile (edad promedio de 7.3 años, 53.04 % niñas y 49.95 % niños). La escala también fue respondida a modo de heterorreporte por 80 madres de los participantes colombianos y las 115 madres de los participantes chilenos. El Análisis Factorial Exploratorio (AFE) arrojó soluciones bifactoriales en todas las muestras y reportó valores de consistencia interna aceptables, aunque la composición de los factores difirió notablemente entre países y entre madres e hijos(as). Los hallazgos se discuten en términos de las diferencias culturales, en la socialización del autocontrol y el desarrollo de la capacidad de autorregulación en los primeros años de la escuela primaria. Se concluye que la medición del autoncontrol en este grupo etáreo mediante la BSCS requiere ajustes.


Abstract The aim of this study was to explore the factor structure of the Brief Self-Control Scale (BSCS; Tangney, Baumeister and Boone, 2004) used as self-report with a sample of 151 participants in Colombia (mean age 8.2 years, 50.33 % girls and 49.66 % boys) and 115 participants in Chile (mean age 7.3 years, 53.04 % girls and 49.95 % boys). The scale was also answered as a hetero-report by 80 mothers of the Colombian participants and the 115 mothers of the Chilean participants. The Exploratory Factor Analysis (EFA) revealed bifactor solutions in all samples and reported acceptable internal consistency values, although the composition of the factors differed markedly between countries and between mothers and children. The findings are discussed in terms of cultural differences, in the socialization self-control and development of self-regulation skills in the early elementary school years. According to these findings, the measurement of self-control in this age group using the BSCS requires adjustments.
