RESUMO

INTRODUCTION: the "Questionnaire of habits related to overweight and obesity" was created and validated in Spanish population, and it allows to describe and quantify five dimensions related to overweight and obesity: diet caloric content, eating for psychological well-being, physical exercise, healthy eating, and alcohol consumption. OBJECTIVE: to adapt the questionnaire in Mexican population, assess their psychometric properties, and compare them with those of the Spanish version. METHOD: the original questionnaire was administered to a sample of 493 Mexican patients with overweight or obesity, and different statistical tools have been applied (exploratory and confirmatory factor analysis, reliability analysis) to know the psychometric properties of the Mexican version and its degree of similarity to the original version. RESULTS: the questionnaire adapted to the Mexican population exhibits the same dimensions as those obtained in the Spanish population (caloric content of the diet, eating for psychological well-being, physical exercise, alcohol consumption and healthy eating), and their psychometric properties are very similar to those obtained for the original questionnaire. CONCLUSION: as a consequence of the adaptation process, a questionnaire with good psychometric properties suitable to measure the lifestyle habits related to overweight and obesity is now available.

RESUMO

Introducción: el "Cuestionario de hábitos relacionados con el sobrepeso y la obesidad" es un cuestionario creado y validado para la población española que permite describir y cuantificar varias dimensiones relacionadas con el sobrepeso y la obesidad: contenido calórico de la dieta, comer por bienestar psicológico, ejercicio físico, alimentación saludable y consumo de alcohol. Objetivo: adaptar el cuestionario a la población mexicana, analizar sus propiedades psicométricas y compararlas con las de la versión española. Método: se ha administrado el cuestionario original a una muestra de 493 pacientes mexicanos con sobrepeso u obesidad y se han aplicado diferentes herramientas estadísticas (análisis factorial exploratorio y confirmatorio, análisis de fiabilidad) para conocer las propiedades psicométricas de la versión mexicana y su grado de parecido con la versión original. Resultados: las dimensiones del cuestionario adaptado a la población mexicana son las mismas que las obtenidas en la población española y sus propiedades psicométricas son muy parecidas a las del cuestionario original. Conclusión: como consecuencia del proceso de adaptación, disponemos de un cuestionario con buenas propiedades psicométricas apropiado para medir los hábitos de vida relacionados con el sobrepeso y la obesidad

RESUMO

Since work organizations became the subject of scientific research, how to operationalize and measure dimensions of work design has been an issue, mainly due to concerns about internal consistency and factor structure. In response, Morgeson and Humphrey (2006) built the Work Design Questionnaire -WDQ-, an instrument that identifies and measures these dimensions in different work and organizational contexts. This paper presents the instruent's adaptation into Spanish using reliability and validity analysis and drawing on a sample of 1035 Spanish workers who hold various jobs in an array of occupational categories. The total instrument's internal consistency was Cronbach's alpha of .92 and the various scales' reliability ranged from .70 to .96, except for three dimensions. There was initially a difference in the comparative fit of the two versions' factor structures, but the model with 21 work characteristics (motivational -task and knowledge-, social, and work context) showed the highest goodness of fit of the various models tested, confirming previous results from the U.S. version as well as adaptations into other languages and contexts. CFA results indicated goodness of fit of factor configurations corresponding to each of the four major categories of work characteristics, with CFI and TLI around .90, as well as SRMR and RMSEA below .08. Thus it brings to the table a reliable, valid measure of work design with clear potential applications in research as well as professional practice, applications that could improve working conditions, boost productivity, and generate more personal and professional development opportunities for workers.

RESUMO

Se compara la precisión en la recuperación de parámetros del Análisis de Estructura de Covarianza (ACOV) y el Modelo de Rutas mediante Mínimos Cuadrados Parciales (PLS-PM), en un modelo simple con variables manifiestas simuladas con escala ordinal de cinco puntos. Se utiliza un diseño experimental, manipulando el método de estimación, tamaño muestral, nivel de asimetría y tipo de especificación del modelo. Se valora la media de las diferencias absolutas para el modelo estructural. ACOV presenta estimaciones más precisas que PLS-PM, en distintas condiciones experimentales. Cuando se utiliza un tamaño muestral pequeño, ambas técnicas son igualmente precisas. Se sugiere utilizar ACOV frente a PLS-PM. Se desaconseja fundamentar la elección de PLS-PM frente a ACOV en la utilización de una muestra pequeña.


The accuracy on parameter recovery is compared between Structure Covariance Analysis (ACOV) and Partial Least Squares Path Modeling (PLS-PM), with simulated ordinals data with 5 points, in a simple model. An experimental design is used, controlling the estimation method, sample size, skewness level and model specification. Mean absolute differences are used to assess accuracy for the structural model. ACOV provided more accurate estimates of the structural parameters than PLS-PM in different experimental conditions. With a small sample size, both techniques are equally accurate. Using ACOV against PLS -PM is suggested. PLS choosing ACOV instead based on the use of a small sample size is not recommended.

RESUMO

The following study will present findings on the validity of the adaptation of the Burger and Cooper’s Desirability of Control Scale into Spanish. Two samples are present: the first involving 1,999 people to study their psychometric properties. In the second sample, 111 people were included to estimate test/ retest reliability. Cultural adaptation was performed using the translation & back-translation method. Item analysis, internal consistency and test/retest reliability were assessed, then evidence of the validity of the internal structure was determined by using exploratory and confirmatory factor analysis. Subject recruitment was performed to gather the 1,999 subjects stratified by age, gender quotas as designed in the sampling plan. Of the subjects, 51% were female, average age of 45 years old (SD = 17.5). All items from the original scale were understood correctly, while five items presented ceiling effect. Cronbach’s alpha = .736 and a test-retest correlation r = .713 were obtained. The factor structure indicated the presence of four dimensions: forecast, autonomy, power and influence and reactance which were reassured in the confirmatory analysis (χ2/df = 4.805, CFI =.932, TLI =.954, RMSEA = .062). The basic dimensions of the scale have shown to be stable and well-defined, though not perfect. The scope, possible applications of the scale and further research are later proposed and discussed (AU)


Se presenta la adaptación y validación al español de la Escala de Deseo de Control de Burger y Cooper. Se emplearon dos muestras. Para estudiar las propiedades psicométricas de la escala se contó con una primera muestra de 1999 (Medad = 45 años, DS = 17,5; 51% mujeres). Para estimar la fiabilidad test-retest se contó con una segunda muestra de 111 personas. La adaptación cultural se llevó a cabo mediante el procedimiento de traducción-retrotraducción. Se presentan las evidencias de validez de la estructura interna de la escala mediante los resultados de sendos análisis factoriales, exploratorio y confirmatorio. El análisis de ítems reveló que todos los elementos presentaron unos valores aceptables, aunque cinco de ellos mostraron efecto techo. El Alfa de Cronbach fue de .736 y la Fiabilidad test–retest fue de .713. La estructura factorial indicó la presencia de cuatro dimensiones: previsión, autonomía, poder e influencia y reactancia. La estructura fue corroborada en el análisis confirmatorio (χ2/df = 4.805, CFI = .932, TLI = .954, RMSEA = .062). Las dimensiones de la escala son estables y específicas, aunque no perfectas. Se discute el alcance y posibles aplicaciones de la escala y se proponen futuras investigaciones (AU)

RESUMO

The present study considers the importance of analyzing what very powerful or influential people think about their employees. We assumed that belonging to a specific category has a differential effect on the perception of others' thoughts in the organization ("meta-representation"). Therefore, experts in organization and human resources from diverse organizations and institutions assessed seven dimensions which structure the organizational image (context, structure, organizational processes, working climate, culture, satisfaction and efficacy). The results showed that belonging to a group (managers or leaders, academicians, consultants, technicians or employees' representatives) modulated the meta-representation, as the experts' opinion about what they think that the employees consider important was related to their group. This was specifically the case for the managers' and leaders' representations, which differed from the other groups and especially from that of the technicians and employees' representatives. The implications of the present findings are discussed.

RESUMO

En el presente estudio se plantea la relevancia de conocer cuál es la representación de quienes ostentan un rol de poder o experto respecto a la imagen que tienen los trabajadores de su organización. Se propone que la pertenencia a un determinado grupo de expertos ejerce un efecto diferencial sobre la representación de esta imagen (metarrepresentación). Para ello, expertos en Organización y Recursos Humanos pertenecientes a diversas organizaciones e instituciones evaluaron siete dimensiones que estructuran la imagen organizacional (contexto, estructura, procesos organizacionales, clima, cultura, satisfacción y eficacia). Los resultados obtenidos sugieren que la pertenencia a una categoría de experto (directivos o mandos, académicos, consultores, técnicos o representantes de los trabajadores) modulaba la metarrepresentación. Se encontró una relación entre la opinión de los expertos sobre la imagen que tienen los trabajadores de su organización con su grupo de pertenencia. Específicamente, la representación de los directivos difería del resto de representaciones estudiadas, especialmente respecto a los grupos de técnicos y representantes de los trabajadores. Se discuten las implicaciones de los resultados (AU)

RESUMO

En este trabajo se evalúa la incidencia de la atenuación, mediante transformaciones de variables, del sesgo y de la curtosis de las puntuacionesobservadas, sobre la estructura factorial, estimada mediante análisis factorial exploratorio y confirmatorio. Los datos proceden de una escala de opinión estudiantil para la evaluación de profesores universitarios, de 16 ítems medidos en escala Likert. Las distribuciones observadas no se aproximan ala normalidad, por lo que se aplican distintos procedimientos para la corrección del sesgo y de la curtosis. Los resultados sugieren que tanto losestadísticos globales de bondad de ajuste como las saturaciones factoriales de los modelos son más sensibles al método de estimación (para una mismatransformación) que a la transformación (para un mismo método de estimación). Como conclusión, cuando la muestra tiene un tamaño moderado y el modelo está especificado correctamente la estimación demáxima verosimilitud proporciona los mejores resultados, aún en condiciones de distanciamiento del supuesto de normalidad multivariante, siempre que el coeficiente de Mardia no supere el valor 70. Una limitacióndel trabajo es que no se ha valorado el efecto de la complejidad de la estructura factorial y/o el grado de comunalidad teórica de las variables


The reduction of skewness and kurtosis of observed variables by data transformation: Effect on factor structure. The present paper examines the effect of skewness and kurtosis reduction through data transformation on the factor structure obtained by exploratory and confirmatory factor analyses. Data are from a 16-item scale that measures students’ opinionsabout university teaching, each item measured on a 5-point Likert format. Observed distributions do not comply with the assumption of normality, sodifferent variable transformations were performed to reduce the skewness and kurtosis of the data. Our results suggest that goodness-of-fit indices andfactor loadings are more sensitive to the estimation method employed (for a given transformation) than to the transformation procedure (for a givenestimation method). For moderate sample sizes and correctly specified models maximum likelihood estimation method is the one that performs the best, even when assumption of multivariate normality is violated, provided the Mardia coefficient falls in the range up to 70. Neither the complexity of factor structure nor the theoretical commonality among variables were taken into account, thus limiting the present results (AU)

RESUMO

OBJECTIVE: To measure the extent to which stress, social support, and self-esteem are predictors of an individual's mental and physical health. Structural equations were integrated with previously-estimated partial models, which simplify the relationships among variables. METHODS: The study sample included 283 women with children. All of the participants resided in the municipality of General Escobedo, state of Nuevo León, Mexico. The surveys were carried out in the second semester of 2003, in the participants homes, using self-evaluation questionnaires to measure each of the variables included in the model. Each participant completed the questionnaire in one sitting. Results were analyzed with AMOS 5.0, employing the maximum likelihood method, often utilized in structural equation models. RESULTS: The results indicate an acceptable adjustment in the proposed model: (chi2/gl=3.03, goodness of fit (GFI)=0.894, adjusted goodness of fit (AGFI)=0.848, root mean square error of approximation (RMSEA)=0.08, incremental fit index (IFI)=0.910). Variances were 31.9% with regard to stress, 27.4% with regard to physical health, and 72.1% with regard to mental health. CONCLUSIONS: Social support and self-esteem are predictors of stress; age and stress are predictors of physical health; and stress, self-esteem, and physical health are predictors of mental health.

RESUMO

Este estudio tiene como objetivo analizar las propiedades psicométricas de una versión española del Inventario de Preocupación de Pensilvania (PSQW) adaptada para su empleo con personas mayores, en la que todos los ítems fueron planteados en sentido positivo para evitar dificultades de comprensión. La muestra se compuso de 97 personas mayores, seleccionadas, mediante muestreo aleatorio a partir del censo de una localidad urbana. El PSQW fue concebido originalmente como un cuestionario unidimensional de evaluación de la preocupación-rasgo o tendencia general a preocuparse. La versión adaptada para personas mayores empleada aquí también funciona de manera unidimensional, aunque los cinco ítems que fueron invertidos respecto a la escala original presentan las saturaciones más bajas en el componente extraído. El PSQW presenta una sensibilidad y especificidad elevadas para la identificación del Trastorno de Ansiedad Generalizada (TAG), si bien no existe suficiente evidencia que distinga entre personas mayores con TAG o con depresión mayor. Además, el PSQW presentó una elevada consistencia interna y correlaciones significativas y moderadamente altas con escalas que evalúan constructos conceptualmente relacionados, como contenidos de preocupación, ansiedad-rasgo y depresión (AU)
