El instrumento utilizado es la adaptacion del "Cuestionario de teorias implicitas del profesorado sobre la ensenanza" (Marrero, 1988a). El analisis de contenido de la estructura resultante de los analisis factoriales realizados permite establecer tres orientaciones de la ensenanza con sentido teorico que permiten concluir que las teorias …
Prospective elementary teachers’ perceptions of the processes of modeling: A case study
2012
In this paper we discuss a study on the approaches to modeling of students of the 4-year elementary school teacher program at the University of Palermo, Italy. The answers to a specially designed questionnaire are analyzed on the basis of an a priori analysis made using a general scheme of reference on the epistemology of mathematics and physics. The study is performed by using quantitative data analysis methods, i.e. factorial analysis of the correspondences and implicative analysis. A qualitative analysis of key words and terms used by students during interviews is also used to examine some aspects that emerged from the quantitative analysis. The students have been classified on the basis…
Importance of considering interoceptive abilities in alexithymia assessment
2019
Background Recent studies have shown that people with high alexithymia scores have decreased interoceptive abilities, which can be associated with psychological and physical disorders. Early assessments of the alexithymia trait included the evaluation of these abilities through the dimension measuring the difficulty in identifying and distinguishing between feelings and bodily sensations (the 26-item Toronto Alexithymia Scale; TAS-26). The revised version of the TAS, the TAS-20, contains a three-factor solution that does not involve a dimension assessing interoceptive abilities. However, the three items allowing the evaluation of these abilities are still present in the TAS-20. In this con…
Psychometric Properties of the Fatigue Questionnaire EORTC QLQ-FA12 in a Sample of Female Cancer Patients.
2017
Abstract Context Cancer patients frequently suffer from fatigue. Recently, the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life group developed a new 12-item fatigue assessment instrument. Objectives The aim of this study was to psychometrically test this questionnaire in comparison with the three-item fatigue scale of the EORTC QLQ-C30. Methods A sample of 354 patients who were being treated for breast cancer or gynecologic cancer were examined using the new fatigue questionnaire EORTC QLQ-FA12 and the EORTC QLQ-C30 during their hospital stay (t1) and three months after hospital discharge (t2). Confirmatory factorial analyses, item analyses, test-retest re…

¿TIENEN LOS NIÑOS PENSAMIENTOS INTRUSOS ANÁLOGOS A OBSESIONES? PRESENTACiÓN DE UN INSTRUMENTO ESTANDARIZADO Y RESULTADOS PRELIMINARES
2007
Los pensamientos intrusos no deseados con contenidos similares a las obsesiones clínicas, constituyen una experiencia prácticamente universal en adultos sin psicopatologías. Sin embargo, no existen apenas evidencias de la presencia de estas introsiones en población infantil y pre-adolescente. En este trabajo se presenta el Inventario de Pensamientos Intrusos Obsesivos para Nif'los y Adolescentes (INPIOS-NA), que recoge en 45 items la frecuencia con que se experimentan intrusiones con temática obsesivo-compulsiva. Lo completaron 122 nif'los (12 y 13 af'los). El análisis factorial exploratorio produjo cuatro factores: 1) Agresión, sexo, acumulación; 2) Contaminación y dudas; 3) Superstición y…
Familial and Parental Predictors of Physical Activity in Late Adolescence: Prospective Analysis over a Two-Year Period
2021
Children’s health behaviors are highly influenced by their parents and family. This study aimed to prospectively evaluate the parental/familial factors associated with physical activity levels (PALs) among older adolescents. The participants were 766 adolescents, who were prospectively observed at baseline (when they were 16 years of age), at first follow-up measurement (FU1
FACTORIAL ANALYSIS OF FISCAL PRESSURE IN ROMANIA: 2008 - 2011
2013
The existence of any modern state is unthinkable without a tax system's efficiency and performance through pressure on taxpayers. Tax burden may be easier as long as it is not excessive. This paper aims to analyze the factors which influence overall tax burden calculated at the Romanian state budget level by using two factorial models for decomposition of the tax burden, a synthetic one and an analytical one. This goal is preceded by a dynamic and structural approach of the tax burden in Romania during 2000 - 2011 in relation to changes in tax burden of the EU Member States.
