The aim of the present study is to illustrate how the appropriate or inappropriate application of exploratory factor analysis (EFA) can lead to quite different conclusions. To reach this goal, we evaluated the degree to which four different programs used to perform an EFA, specifically SPSS, FACTOR, PRELIS and MPlus, allow or limit the application...
Background: In the context of cognitive appraisal, the Work Confl ict
Appraisal Scale (WCAS) was developed to assess work confl ict in terms
of threat and challenge. Method: In the fi rst study, the factorial structure
of the scale was tested using confi rmatory factor analysis with a Spanish
multi-occupational employee sample (N= 296). In the sec-...
Based on Job Demands-Resources Model (JD-R), this study examines the relationships among teacher support resources, psychological need satisfaction, engagement and burnout in a sample of 282 Spanish secondary school teachers. Nine teacher psychological needs were identified based on the study of Bess and on the Self-Determination Theory (SDT). Self...
Con el fin de proporcionar información técnica sobre los tests editados en España, y siguiendo el proceso de evaluación de algunos de los tests más empleados en nuestro país, el presente artículo presenta los resultados de la tercera evaluación de tests llevada a cabo desde la comisión de tests del Colegio Oficial de Psicólogos. En concreto se han...
Abstract: Exploratory Factor analysis is one of the techniques used in the development, validation and adaptation of psychological measurement instruments. Its use spread during the 1960s and has been growing exponentially thanks to the advancement of information technology. The criteria used, of course, have also evolved. But the applied researche...
El Análisis Factorial Exploratorio es una de las técnicas más usadas en el desarrollo, validación y adaptación de instrumentos de medida psicológicos. Su uso se extendió durante los años 60 y ha ido creciendo de forma exponencial al ritmo que el avance de la informática ha permitido. Los criterios empleados en su uso, como es natural, también han e...
La estructura de muchos constructos bipolares se estudia habitualmente mediante escalas contrabalanceadas tipo Likert. Las respuestas a estas escalas son sometidas a análisis factorial, pero con frecuencia, la estructura factorial descubierta no es bipolar, sino que cada dimensión supuestamente bipolar se descompone en dos factores monopolares. Est...
This study presents a personality evaluation instrument adapted to the vocational setting: the Adaptive Vocational Personality Questionnaire (AVPQ). The questionnaire was developed and tested in a sample of 2160 university students in the final years of their degree programs. The purpose of the study is to validate the questionnaire, providing evid...
The objective of this study is to test the validity of the collective climate concept. It was expected that membership in collective climates was related to membership in the collectivities defined by departmental membership, hierarchical level, shift, job location and organizational tenure. The study sample was composed of 195 employees from a cen...
La validite de construction des echelles de Rizzo, House, et Lirtzman (1970) a ete fortement critiquee ces dernieres annees. Les critiques portent sur la formulation des items qui constituent ces echelles, ce qui fait que l'interpretation des echelles depend totalement de la formulation des items. Ces critiques ont favorise l'emergence d'autres mod...
Burnout researchers have proposed that the conceptual opposites of emotional exhaustion and cynicism (the core dimensions of burnout) are vigor and dedication (the core dimensions of engagement), respectively (
[11] and [24]). We tested this proposition by ascertaining whether two sets of items, exhaustion–vigor and cynicism–dedication, were scalab...
Ambiguous response formats predict correlations from -.467 to -1 between opposite items, depending on whether the respondent's interpretation of the format is unipolar or bipolar. The authors present a procedure to investigate the proper interpretation in each case. It consists of applying nonparametric and parametric item response theory models (t...
The structure of bipolar constructs is often studied using counterbalanced Likert-type scales. Answers obtained by means of these scales have been submitted to factor analysis, and contrary to expectations, the results frequently have shown that the obtained factor structure is not bipolar, but made up by two monopolar factors. Recently, Van Shuur...
Tested a causal model of the determinants and consequences of role stress in 2 independent samples of 190 nurses (72% women) and 206 physicians (75% men) working in primary health care teams. Data were obtained by questionnaire. The model includes job autonomy, feedback from colleagues, goal standardization, tenure, and workload as role stress ante...
EN LA LITERATURA NO SE ENCUENTRAN ESTUDIOS QUE COMPAREN LAS PROPIEDADES PSICOMETRICAS DE MEDIDAS MONOITEM Y MULTIITEM DE UN MISMO CONSTRUCTO. ESTO PUEDE SER DEBIDO A QUE PREVALECE EL CRITERIO RAZONALBE DE QUE ES SIEMPRE MAS ADECUADO UTILIZAR MEDIDAS MULTIITEM. POR ELLO, EL OBJETIVO DEL PRESENTE TRABAJO ES ANALIZAR Y COMPARAR LAS PROPIEDADES PSICOME...
