PRÁCTICAS DEL ANÁLISIS FACTORIAL EXPLORATORIO (AFE) EN LA INVESTIGACIÓN SOBRE CONDUCTA DEL CONSUMIDORY MARKETING
2012
El Análisis Factorial Exploratorio (AFE) es una de las técnicas estadísticas más utilizadas en la investigación social. El principal objetivo de este trabajo es describir las prácticas más utilizadas por los investigadores en el área de la conducta del consumidor y el marketing. Mediante una metodología de revisión documental se analizan las prácticas de AFE en cinco revistas españolas dedicadas a dicha temática (2000-2010). Se analizan las elecciones de los investigadores relacionadas con el modelo factorial, el criterio de retención, la rotación, la interpretación de los factores y otras cuestiones relevantes para el análisis factorial. Los resultados sugieren que los investigadores ejecu…
Values and Personal Life Investment in Middle-Age: Measures and Relations
2015
The present study analyzed the factor structure of Schwartz Value Survey (SVS; 46 items) and the personal life investment (PLI; 10 items) scale, as well as the mutual relations between these two measures. The 50-year-old participants (n = 217–224) were drawn from the ongoing Finnish Jyväskylä Longitudinal Study of Personal and Social Development. For the SVS, the confirmatory factor analysis (CFA) supported the 14-factor structure: achievement, tradition, stimulation, hedonism, security, conformity, power, universalism (with sub-factors of societal concern, tolerance and protecting nature), benevolence (with sub-factors of caring and dependability) and self-direction (with sub-factors of au…
Longitudinal factorial invariance of the Maslach Burnout Inventory-General Survey among employees with job-related psychological health problems
2011
The study provides new knowledge about the longitudinal factorial invariance of the Maslach Burnout Inventory-General Survey (MBI-GS). In order to investigate the factor structure of the MBI-GS and its invariance across time, a full panel data with two measurements gathered among employees with job-related psychological health problems was used. Consistent with previous study findings, the results indicated that the correlated three-factor model of the MBI-GS (i.e. exhaustion, cynicism and professional efficacy) showed a better fit with the data than the alternative factor models. The correlated three-factor structure was invariant across time, indicating that the scale has good construct v…
An Examination of the Structure of the Career Decision Self-Efficacy Scale (Short Form) Among Italian High School Students
2013
This study aims to evaluate the factor structure of Career Decision Self-Efficacy scale-short form in a sample of Italian high school adolescents. confirmatory factor analysis (CFA) was used to test the degree to which a one-factor structure and a five-factor structure provided the best fit. In view of available research the five-factor structure was expected to provide the best fit. Moreover, factorial invariance in males and females was tested. It was expected to be invariant across groups. As expected the five-factor structure showed a better fit than the one-factor model and the factorial invariance resulted invariant across boys and girls.
Measurement invariance of the Behavioural Regulation in Sport Questionnaire when completed by young athletes across five European countries
2013
The purpose of this study was (1) to examine the factorial validity of the Behavioural Regulation Sport in Questionnaire (BRSQ) when completed by young soccer players in the Promoting Adolescent Physical Activity (PAPA) project (9-15 years old) in 5 European countries (France: n = 1248, Greece: n = 1507, Norway: n = 1397, Spain: n = 2245, and England: n = 1372) and (2) test the measurement invariance of its latent factors across these 5 countries.First, we tested the exploratory structural equation model (ESEM) factor analyses, allowing cross-loadings between factors, against the traditional independent clusters confirmatory factor analysis model (ICM-CFA), with all cross-loadings constrain…
The Posttraumatic Stress Disorder Factorial Structure: Findings from a Multicultural Sample
2020
Although several studies exploring Posttraumatic Stress Disorder (PTSD) factorial structure have been conducted, few of them have tested the ICD-11 and the DSM-5-based models in samples from low-in...
Factor structure and stability of a quality questionnaire within a postgraduate program
2017
En este trabajo se describe un instrumento basado en el uso de una técnica de análisis factorial con el fin de medir la calidad de la educación a través de una muestra de estudiantes de postgrado de una universidad pública española. El instrumento tiene unas aceptables propiedades psicométricas (fiabilidad y validez). En cuanto a la solución factorial, tres dimensiones principales se han determinado: la importancia dada a la materia; recursos educativos y conocimiento de la materia (anterior y posterior). Es importante destacar que estas tres dimensiones se han detectado consistentemente en todo el análisis factorial: muestra total y cursos separados. Estas tres dimensiones deben ser consid…
Adaptation of the Body Image after Breast Cancer Questionnaire in the Polish context: factorial structure and validity of the scale
2016
<b>Background</b><br /> Valid assessment of body image is salient in therapy and rehabilitation of women suffering from breast cancer. Adequate instruments are still lacking in this domain. To overcome this limitation two aims were formulated in the study. First, we tested the factorial structure of the Body Image after Breast Cancer Questionnaire (BIBCQ) developed by Baxter (1998) in Canada, in the Polish context. Then, we tested the construct validity of the scale. The scale is based on a multidimensional concept of the body image of chronically ill individuals proposed by Vamos (1993).<br /> <br /> <b>Participants and procedure</b><br /> A …
Italian adaptation of the Group Questionnaire: validity and factorial structure
2020
The Group Questionnaire (GQ) is a measure recently developed by Krogel et al. (2013) for the evaluation of the therapeutic relationship in group. The GQ identifies a three-factor model of the relationship that allows to measure quality (Positive Bonding, Positive Working and Negative Relationship) and structure (member-member, member-leader and member-group), dimensions in group. This work shows the results of a first study on the Italian validation of the GQ. In this study the GQ was administered to 536 subjects from 32 non-clinical groups of undergraduate students. The cross-cultural validity of the GQ in the Italian population has been examined by comparing the psychometric properties an…
Evidencias de validez interna de un instrumento para evaluar la colegialidad docente
2019
Este estudio es parte de una investigación más amplia que busca diseñar un modelo de evaluación de los sistemas educativos basado en la mejora de la cohesión social. Se trata de un estudio de validación métrica de un instrumento de evaluación de la colegialidad docente. El instrumento se aplicó a partir de las conclusiones del estudio de validación por comités de expertos. La muestra estuvo formada por 147 profesores voluntarios de primaria y secundaria de España. La metodología utilizada se basó en la recogida de evidencias métricas de validez interna del instrumento; se estudió la dimensionalidad mediante el análisis factorial exploratorio y la capacidad de discriminación mediante el anál…
