The exploratory factor analysis of items: guided analysis based on empirical data and software
2017
El objetivo del presente trabajo es ilustrar cómo la aplicación adecuada o inadecuada del análisis factorial exploratorio (AFE) puede llevar a conclusiones muy diferentes. Para ello se evalúa el grado en que cuatro paquetes estadísticos diferentes que permiten realizar AFE de ítems, en concreto SPSS, FACTOR, PRELIS y MPlus, permiten o limitan la aplica- ción de los estándares actualmente recomendados en materia de análisis factorial. Asimismo se analizan y comparan los resultados que ofrecen di- chos programas cuando se factorizan datos empíricos de escalas que ajus- tan, según el caso, de manera inadecuada, ambigua u óptima a los supuestos del modelo AFE lineal clásico, a través de las dis…
Spanish Validation of the Leader Empowering Behavior Questionnaire (LEBQ)
2019
The concept of empowering leadership has attracted widespread academic and practical interest and different questionnaires have been developed to measure it. However, there are no instruments to measure empowering leadership in the Spanish language. This article presents the translation, adaptation, and validation of a scale to measure this construct. In addition, it analyzes the relationship between managers’ empowering leadership and employees’ job satisfaction. In turn, the study analyzes whether employees who participate in a greater number of continuous improvement programs have supervisors who favor more empowering behaviors. A total of 739 participants with various occupations from d…
IT Technology Implications Analysis on the Occupational Risk: Cloud Computing Architecture
2014
Abstract The present paper is divided into three major areas: the analysis of occupational risk implications at national and international level, the European priorities in terms of occupational risk and the existing cloud computing services. Since human resource is present within each organization, it is required a comprehensive and actual assessment of the processes in which they participate. Like in any daily activity, processes and people contribute to the emergence of risks. If each organization creates healthy and safe workplaces that means that it contributes to the sustainable development of the area in which it operates. It can be said that occupational risk assessment and occupati…
Propiedades psicométricas de la Escala de Victimización Escolar entre Iguales (VE-I)
2018
<p>La violencia escolar entre iguales tiene graves consecuencias para las víctimas. La victimización puede ser directa, mediante agresiones físicas y verbales, y relacional mediante exclusión y rechazo social. El objetivo de este estudio fue analizar las propiedades psicométricas de la escala de Victimización Escolar entre Iguales (VE-I) que consta de 11 ítems relativos a diferentes formas de victimización. En este estudio participaron 1389 adolescentes (50.45% varones), de entre 11 y 15 años (M = 13.37, DE = 1.23). La estructura de la escala fue analizada mediante análisis factorial exploratorio y análisis factorial confirmatorio, por lo que se utilizaron dos submuestras diferentes.…

Measurement Invariance and Construct Validity of the Satisfaction With Life Scale (SWLS) in Community Volunteers in Vietnam.
2022
Worldwide, the Satisfaction With Life Scale (SWLS) has become the most widely used measure of life satisfaction. Recently, an authorized Vietnamese-language version has been introduced. Using a convenience sample comprising community volunteers from Ho Chi Minh City (N = 1073), confirmatory support was found for the cross-national constancy of the one-dimensional structure underlying the SWLS. Corrected item–total polyserial correlations and Omega coefficient were satisfactory. Using multi-group confirmatory factor analysis, configural, metric, and scalar invariance of the SWLS factorial structure were tested by gender, age, marital status, income, and educational level. Strong evidence of …

Psychometric analysis of a perception scale on the usefulness of Moodle in the University
2014
Because of the relevance acquired by the learning management systems in higher education, and the spread of use of the Moodle platform in many academic institutions, a scale of perceived usefulness on the use of Moodle in this context is designed. Furthermore, the study tested the psychometric validity of the scale. The aim is to provide a reliable and valid instrument to measure the students’ perception about the usefulness of Moodle. From the population of university students in Educational Sciences field, the study obtained a sample of 754 subjects. The results show that the scale evaluates the utility of the platform adequately in five dimensions: content, activities, assessment, intera…
An adaptation of the Critical Thinking Disposition Scale in Spanish youth
2020
Abstract Background Enhancing students’ critical thinking (CT) is an essential goal of higher education. Although there are many instruments to assess its cognitive dimension, this is not so in the case of dispositional thinking. Our aim is to examine the psychometric properties of the Spanish version of the Critical Thinking Disposition Scale (CTDS; Sosu, 2013). Method Data come from 1064 students in their final years at high school and university in Spain. We report validity evidence based on its internal structure by confirmatory factor analysis (CFA) and an estimation of reliability and measurement invariance by gender. Additionally, nomological validity study with a multiple-indicator …
The structure of Antonovsky's Orientation to Life Questionnaire
1998
The present study investigated the structure of Antonovsky's (1987) short-form (13-item) Orientation to Life Questionnaire (OLQ). The OLQ was developed to measure sense of coherence, which consists of three interrelated components: meaningfulness, comprehensibility and manageability. Confirmatory factor analyses were carried out using data on three occupational groups (technical designers n = 989, teachers n = 1012, managers n = 1035). The factor analysis models were specified and compared in the study: (1) a first-order one-factor model; (2) a first-order correlated-three-factor model; and (3) a second-order model with three first-order factors. The results suggested that the first-order c…
