Propiedades Psicométricas de la Escala de Creencia en un Mundo Justo General y Personal en el Contexto Argentino
2018
El objetivo principal de este trabajo fue analizar las propiedades psicométricas de las Escalas de Creencia en un Mundo Justo General y Personal. Para tal fin, se examinó la estructura interna de ambas, testeando si evalúan un mismo constructo global o constituyen dos dimensiones diferenciadas, la consistencia interna de cada una y sus relaciones con las orientaciones religiosas. Participaron del estudio 328 estudiantes universitarios de la Ciudad Autónoma de Buenos Aires con edades entre 18 y 40 años (M = 24,1; DT = 3,88). El 36,6% eran hombres (n = 120) y el 63,4% mujeres (n = 208). Los resultados del estudio sugieren propiedades psicométricas adecuadas para ambas escalas de CMJ. Además, …

2014
El objetivo de esta investigación es presentar una adaptaciòn y validación en población española de la Escala de expectativa de los hijos adolescentes sobre la reacción de sus padres frente al comportamiento prosocial y antisocial,desarrollado por Wyatt y Carlo (2002). La muestra estuvo compuesta por 631 adolescentes españoles de entre 15 y 18 años de edad,de ambos sexos, de clase media. Se realizó un análisis factorial confirmatorio para estudiar la validez de constructo de la escala y se analizó la consistencia interna a través de del cálculo de alpha de Cronbach.Los resultados indican que la escala posee buenos índices de ajuste al modelo teórico propuesto por los autores en su versión o…
Validación de la Escala de Satisfacción con la Vida y su relación con las dimensiones del Autoconcepto en universitarios peruanos
2018
Life satisfaction has been the object of several studies, mostly assessed with the Satisfaction with Life Scale (SWLS). Recently, interest has been shown in the relationship between life satisfaction and self-concept, because life satisfaction seems to depend on the cultural context. The purpose of this research was to study the properties of the SWLS in a sample of Peruvian students, and to analyze the relationship between life satisfaction and self-concept in the Peruvian context. The study population consisted of 527 university students from Lima, Peru. Firstly, a confirmatory factor analysis was estimated and assessed, and reliability estimates of the scale and its items were calculated…
Validación del Autoconcepto Forma 5 en Universitarios Peruanos: Una Herramienta para la Psicología Positiva
2015
ResumenEl autoconcepto, aunque central en la psicología tradicional, ha cobrado importancia recientemente en el contexto de la psicología positiva. El Autoconcepto Forma 5 (AF5) es una medida muy utilizada en el contexto hispanohablante. Sin embargo, no existen estudios sobre sus propiedades psicométricas más allá de la fiabilidad en población peruana. El objetivo es presentar las propiedades psicométricas de la escala multidimensional AF5 en universitarios peruanos. Se recogió una muestra de 527 estudiantes universitarios. La encuesta incluyó, además del AF5, medidas de esperanza disposicional y satisfacción con la vida. Se llevó a cabo un análisis factorial confirmatorio para evaluar la v…
The grapevine flagellin receptor VvFLS2 differentially recognizes flagellin-derived epitopes from the endophytic growth-promoting bacterium Burkholde…
2014
International audience; The role of flagellin perception in the context of plant beneficial bacteria still remains unclear. Here, we characterized the flagellin sensing system flg22-FLAGELLIN SENSING 2 (FLS2) in grapevine, and analyzed the flagellin perception in the interaction with the endophytic plant growth-promoting rhizobacterium (PGPR) Burkholderia phytofirmans. The functionality of the grapevine FLS2 receptor, VvFLS2, was demonstrated by complementation assays in the Arabidopsis thaliana fls2 mutant, which restored flg22-induced H2O2 production and growth inhibition. Using synthetic flg22 peptides from different bacterial origins, we compared recognition specificities between VvFLS2…
Urban upbringing and childhood respiratory and allergic conditions: A multi-country holistic study
2018
Objective: We integratively assessed the effect of different indoor and outdoor environmental exposures early in life on respiratory and allergic health conditions among children from (sub-) urban areas. Methods: This study included children participating in four ongoing European birth cohorts located in three different geographical regions: INMA (Spain), LISAplus (Germany), GINIplus (Germany) and BAMSE (Sweden). Wheezing, bronchitis, asthma and allergic rhinitis throughout childhood were assessed using parental-completed questionnaires. We designed “environmental scores” corresponding to different indoor, green- and grey-related exposures (main analysis, a-priori-approach). Cohort-specific…
Psychometric properties of the Satisfaction with Job Life Scale in Portuguese workers: A systematic study based on the IRT and CFA modeling
2020
Job satisfaction is related to better physical and mental health, as well as to factors specifically related to work. In this context, the measurement of work satisfaction is important for organizations that profess an interest in engaged and satisfied workers. Therefore, this study aims to examine the psychometric properties of the Satisfaction with Job Life Scale (SWJLS) in Portuguese workers by combining the procedures of the Classical Test Theory (CTT) and the Item Response Theory (IRT). Specifically, internal structure of the scale was studied, its reliability (consistency), correlations with other measures of wellbeing (life satisfaction, loneliness, emotional wellbeing at work, and j…
Spanish Validation of the Polymorphous Prejudice Scale in a Sample of University Students
2016
ABSTRACTThe shortened version of the Polymorphous Prejudice Scale (PPS) analyzes new manifestations of prejudice toward gay men and lesbian women. Specifically, this instrument consists of 16 items distributed in four subscales: values gay progress, positive beliefs about gay men, positive beliefs about lesbian women, and resistance to heteronormative expectations. The aim of the current study is to add new evidence about the reliability and validity of the scale. The scale is administrated to 348 heterosexual university students from Spain with a mean age of 22.62 years (SD = 7.63). Reliability and factorial validity estimates are presented. A four-factor structure is supported using confi…
The Development and Initial Validation of a Short, Self-Report Measure on Social Inclusion for People with Intellectual Disabilities-A Transnational …
2021
Sport has been promoted as a means of increasing the social inclusion of persons with intellectual disabilities. Suitable tools for evaluating this claim are not readily available. The aim of this study was to develop a self-report tool for use by people with intellectual disabilities regarding the social inclusion they experience in sport and in the community. A three-phase process was used. In the first phase an item bank of questionnaire items was created and field-tested with 111 participants. Initial factor analysis identified 42 items which were further evaluated in Phase 2 with 941 participants from six European countries. Construct validity was established first through Exploratory …
