The exploratory factor analysis of items: guided analysis based on empirical data and software
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…
La aceptación de la enfermedad: una forma de prevención del SIDA
Poner a prueba la eficacia de un programa de prevención dirigido a la población de personas seropositivas. El programa emplea la intervención entre iguales para incre¬mentar la adaptación positiva de la enfermedad (APE) como elemento facilitador de la implicación en el sexo seguro. El programa incluye información sobre sexo seguro y de riesgo y sobre las vías de transmisión del VlH, así como psicoterapia de grupo combina¬da con técnicas dirigidas al incremento de la conciencia corporal. La conciencia corpo¬ral puede ayudar a los pacientes a liberar tensiones psicológicas, y estimular el afronta¬miento de aquellos aspectos que tratan de negar. Hipotetizamos que la sustitución de estrategias …
Construct Validity of Rizzo et al.'s (1970) Role Conflict and Ambiguity Scales: A Multisample Study
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 modeles factoriels. La duplication elargie de Kelloway et Barling (1990), l'analyse factorielle destinee a confirmer la validite des echelles de Rizzo et al. et une echelle de surcharge des roles avec des items formules a la fois affirmativement et negativement furent utilisees pour eprouver la validite de construction des echelles d'ambiguite et de …
The validity of collective climates
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 central administration agency. Using a combination of hierarchical and non-hierarchical clustering methods, three different collective climates were obtained. The results showed that only hierarchical level was related to collective climate membership. Based on all the results obtained, the debate on the validity of collective climates is reconsidere…
Burnout and work engagement: Independent factors or opposite poles?
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 (Maslach & Leiter, 1997; Schaufeli, Salanova, González-Romá, & Bakker, 2002). We tested this proposition by ascertaining whether two sets of items, exhaustion-vigor and cynicism-dedication, were scalable on two distinct underlying bipolar dimensions (i.e., energy and identification, respectively). The results obtained by means of the non-parametric Mokken scaling method in three different samples (Ns = 477, 507, and 381) supported our proposal: the core burnout and engagement d…
Hierarchy of Eustress and Distress: Rasch Calibration of the Valencia Eustress-Distress Appraisal Scale
The purpose of the study was to uncover the hierarchy of eustress and distress appraisal and calibrate the Valencia Eustress Distress Appraisal Scale (VEDAS, Rodríguez, Kozusznik, & Peiró, 2013) using the Rasch Analysis (RA). A cross-sectional study was conducted on sample of 603 Spanish social service professionals. The VEDAS included four subscales addressing work demands that can be appraised as sources of eustress and distress. RA was carried out for eustress and distress appraisal scales. A graduation of stressful situations appraised as distress and/or as eustress was revealed. One of the greatest sources of distress and one of the lesser sources of eustress was “switching off at …
