Cyberbullying among Adolescents: Psychometric Properties of the CYB-AGS Cyber-Aggressor Scale
2020
The present study aims to analyze the psychometric properties of the revised version of the Adolescent Cyber-Aggressor scale (CYB-AGS). This scale is composed of 18 items that measure direct and indirect cyberbullying. A cross-sectional study was conducted using two independent samples of adolescents. The first sample included 1318 adolescents (52.6% girls) from 12 to 16 years old (M = 13.89, SD = 1.32). The second sample included 1188 adolescents (48.5% boys) from 12 to 16 years old (M = 14.19, SD = 1.80). First, to study the psychometric properties of the CYB-AGS, exploratory factor analysis was performed on Sample 1. Results indicated a two-factor structure: direct cyber-aggression and i…
Reliability and validity of the COPE Index among caregivers of disabled people.
2017
Aim To study the reliability and validity of the Carers of Older People in Europe (COPE) Index among caregivers of disabled people of different ages. Methods A cross-sectional design of Finnish caregivers (n = 1117). Exploratory factor analysis (EFA) was performed separately on samples of three different age groups, and the internal consistencies of the subscales were investigated. Results Three factors were identified; Cronbach's alpha was 0.83–0.86 for negative impact and 0.77–0.78 for quality of support, indicating good internal consistency. The third factor, positive value, was less consistent across the age groups (α < 0.66). Conclusions The COPE Index is a valid and reliable screening…
Implicaciones de la COVID-19 sobre el marketing de servicios educativos: un estudio desde las motivaciones y estados de ánimo de universitarios en Co…
2021
Este estudio analizó las implicaciones que tiene la pandemia en la aplicación del marketing de servicios educativos en instituciones de educación superior en Colombia; en particular, se revisaron las implicaciones asociadas con las motivaciones por estudiar y los estados de ánimo presentes en los estudiantes. Para ello, se realizó un estudio empírico en cinco universidades, que recogió las opiniones de 695 estudiantes. Primero, se realizó un análisis factorial exploratorio y luego un análisis clúster. Los resultados evidenciaron las diferentes dificultades que se presentaron en la aplicación del marketing, desde la perspectiva estudiantil. Como resultado, el estudio sugiere algunas recomend…
Organizational learning: Proposal of an integrative scale and research instrument
2014
Abstract This study describes the development and validation of an instrument to measure organizational learning. Starting out from a comprehensive analysis of the main organizational learning models in the specialized literature, the organizational learning scale in this study consists of 18 items forming five dimensions: the ontological levels of learning, modes of knowledge conversion, learning sub-processes, types of learning, and feedback and feed-forward flows of learning. A survey to large Spanish companies provides data from 167 companies. Confirmatory factor analysis tests the construct measurement model and validates the scale. The results of the study indicate that the scale sati…
Using a brief questionnaire to assess the overall perception of basketball spectators
2014
Purpose – The purpose of this paper is twofold. The first aim is to obtain a valid and reliable instrument for the holistic analysis of sporting events, and the second is to test a causal model in which future intentions depend on spectators’ perceptions of quality, satisfaction, and value of these events. Design/methodology/approach – A total of 493 spectators of a professional basketball team in the Spanish ACB league responded to a survey to measure the overall performance of the sporting event service. Exploratory factor analysis and further confirmatory factor analysis using structural equation models provides the methodology for testing the reliability and validity of the instrument.…
Buying Intention, Acceptability and Frequency of Purchase: Analyzing their Determinants using SEM
2019
Considering the growing relevance of Indian retail sector, this research aims to study the consumer buying behaviour towards national brands (NB). More in detail, this research shall explore the determinants of buying intention, acceptability and frequency of purchase developing a model for consumer buying behaviour toward NB. A structured questionnaire was provided to the respondents across Delhi (National Capital Region). At the first stage, exploratory factor analysis (EFA) has been used to test dimensionality of the data with the aim to produce a set of items reflecting the meaning of the relative construct. Then, structural equation modelling (SEM) has been implemented using AMOS in or…
Validación de un cuestionario para evaluar el funcionamiento de las bibliotecas escolares
2018
La biblioteca escolar ha adquirido en los últimos años un nuevo protagonismo, convirtiéndose en un espacio de aprendizaje fundamental para la enseñanza de las distintas áreas y materias y el fomento de competencias en el alumnado. El objetivo de este trabajo es validar un cuestionario diseñado ad hoc para evaluar el funcionamiento y las formas de uso e incorporación de la biblioteca escolar a la actividad pedagógica diaria. Para ello se aplicó el cuestionario a una muestra aleatoria de 4.177 alumnas y alumnos de 358 centros de Educación Primaria, Secundaria y Postobligatoria, se calculó su fiabilidad mediante la prueba de Alfa de Cronbach y se realizó un análisis factorial exploratorio. Los…
Key levels for knowledge creation and management: which is the ontological locus for learning in Spanish manufacturing firms?
2013
This paper aims to highlight two core issues related to knowledge management and organisational learning. First deals with the ontological support-knowledge creation relationship. Secondly, the comparison between Crossan et al. (1999) and Nonaka and Takeuchi (1995) models: on what ontological supports knowledge is created? Individuals, groups and organisation: are they independent or do they interact with each other? Is individual level swallowed up by the group [as Nonaka and Takeuchi (1995) seems to suggest], leading to groups and organisation as unique ontological levels? The empirical study draws those ontological levels in large manufacturing Spanish firms. It identifies (via explorato…
Development of a questionnaire to assay recalled liking for salt, sweet and fat
2012
Abstract Liking for a sweet, salty or fatty diet may induce overconsumption of simple carbohydrates, sodium or lipids. Measuring overall liking of the corresponding sensory sensations contributes to understanding the determinants of dietary behaviours. However, no standardized validated questionnaire assaying these sensations is currently available. In the present study, we developed a web-based questionnaire, “PrefQuest”, which measures recalled liking for the following four sensations: salt, fat and salt, sweet, fat and sweet. PrefQuest included four types of items: (1) liking for sweet, fatty-sweet and fatty-salty foods, (2) preferences in the level of seasoning by adding salt, sweetener…
Refinement and validation of a comprehensive scale for measuring HR practices aimed at performance-enhancement and employee-support
2019
Abstract The purpose of this paper is to refine and validate a Human Resource practices (HRP) scale to measure employees' perceptions and test a two-tier model structured in eight practices and two bundles. In a sample of 554 employees, an EFA (Exploratory Factor Analysis) offered six factors that explained about 70% of the variance. Then, with 1647 employees (from 41 Spanish organizations), first- and second-order models were tested with Confirmatory Factor Analysis (CFA). The former encompasses eight practices. The latter grouped the practices in two bundles, one on enhancing performance and the other on supporting employees. The Cronbach's alpha, Rho coefficient (Composite Reliability Co…
