VALIDACIÓN DE UNA ESCALA PARA EL ANÁLISIS DE LAS PERCEPCIONES DE LOS RESIDENTES SOBRE EL IMPACTO SOCIAL DE UN CENTRO DEPORTIVO
2019
Resumen La finalidad de este estudio es validar una escala para el análisis de las percepciones de los residentes sobre el impacto social de un centro deportivo. Se recogió una muestra de 406 residentes del municipio de Moncada (Valencia), con un error de muestreo de ±4,82, que contestaron a una encuesta de 31 ítems que recogían posibles impactos sociales derivados de la presencia del centro deportivo en la localidad. La aplicación de análisis factorial exploratorio y confirmatorio redujo la escala a 28 indicadores distribuidos en siete dimensiones de impacto: impacto sociocultural, impacto socioeconómico, impacto en la imagen y la promoción del municipio, impacto en el desarrollo urbano y …
Brief report: Assessing dispositional optimism in adolescence – Factor structure and concurrent validity of the Life Orientation Test – Revised
2014
Dispositional optimism is an individual difference promoting psychosocial adjustment and well-being during adolescence. Dispositional optimism was originally defined as a one-dimensional construct; however, empirical evidence suggests two correlated factors in the Life Orientation Test - Revised (LOT-R).The main aim of the study was to evaluate the dimensionality of the LOT-R. This study is the first attempt to identify the best factor structure, comparing congeneric, two correlated-factor, and two orthogonal-factor models in a sample of adolescents. Concurrent validity was also assessed.The results demonstrated the superior fit of the two orthogonal-factor model thus reconciling the one-di…
Gender Confirmation Surgery: Guiding Principles
2016
Abstract Background At this time, no formal training or educational programs exist for surgeons or surgery residents interested in performing gender confirmation surgeries. Aim To propose guiding principles designed to aid with the development of formal surgical training programs focused on gender confirmation surgery. Methods We use expert opinion to provide a “first of its kind” framework for training surgeons to care for transgender and gender nonconforming individuals. Outcomes We describe a multidisciplinary treatment model that describes an educational philosophy and the institution of quality parameters. Results This article represents the first step in the development of a structure…
Self-efficacy and enjoyment of physical activity in children: factorial validity of two pictorial scales.
2019
BackgroundSelf-efficacy and enjoyment are two main constructs proposed within many motivational theories in any human endeavor, sport and physical activity included.MethodsThe purpose of this study was to examine the factor structure of two pictorial scales measuring self-efficacy and enjoyment levels in a sample of 14,035 Italian schoolchildren (7,075 boys and 6,960 girls, 6- to 7-year-olds). An important feature of the two scales is that they are in a pictorial format in order to prompt a straightforward understanding in children. The whole sample was randomly split in two subsamples according to gender and age and the factor structure of the measures was examined across subsamples.Result…
Measuring Social Solidarity. Some Research Notes
2012
Abstract There is an increasing public, political and research interest in social solidarity. Even though the concept has a long history and is embedded in solid approaches, there is not much literature concerned with its measurement. The paper falls into the area of the methodological studies of social solidarity and it deals with construct validation. The objective of this paper is to test for convergent validity and nomological validity of two sets of items aiming to measure social solidarity attitudes and acts. The main method employed is confirmatory factor analysis.
Development of a questionnaire to assay recalled liking for salt, sweet and fat
2012
Abstract Liking for a sweet, salty or fatty diet may induce overconsumption of simple carbohydrates, sodium or lipids. Measuring overall liking of the corresponding sensory sensations contributes to understanding the determinants of dietary behaviours. However, no standardized validated questionnaire assaying these sensations is currently available. In the present study, we developed a web-based questionnaire, “PrefQuest”, which measures recalled liking for the following four sensations: salt, fat and salt, sweet, fat and sweet. PrefQuest included four types of items: (1) liking for sweet, fatty-sweet and fatty-salty foods, (2) preferences in the level of seasoning by adding salt, sweetener…
The Somatic Symptom Disorder - B Criteria Scale (SSD-12): Factorial structure, validity and population-based norms.
2017
The Somatic Symptom Disorder - B Criteria Scale (SSD-12) assesses the psychological features of DSM-5 Somatic Symptom Disorder (SSD). The present study investigates the dimensionality and psychometric properties in a general population sample and provides norm values.Test dimensionality was evaluated via confirmatory factor analysis and nonparametric item response theory. Correlational analyses and logistic regression models based on related measures (SSS 8, PHQ-2, GAD-2, Health Care Utilization) were used to derive predictive validity. Age and gender specific norms were derived via quantile regression.The SSD-12 has good item characteristics and excellent reliability (Cronbach's α=0.95). C…

Refinement and validation of a comprehensive scale for measuring HR practices aimed at performance-enhancement and employee-support
2019
Abstract The purpose of this paper is to refine and validate a Human Resource practices (HRP) scale to measure employees' perceptions and test a two-tier model structured in eight practices and two bundles. In a sample of 554 employees, an EFA (Exploratory Factor Analysis) offered six factors that explained about 70% of the variance. Then, with 1647 employees (from 41 Spanish organizations), first- and second-order models were tested with Confirmatory Factor Analysis (CFA). The former encompasses eight practices. The latter grouped the practices in two bundles, one on enhancing performance and the other on supporting employees. The Cronbach's alpha, Rho coefficient (Composite Reliability Co…
Assessing Time Management Skills as an Important Aspect of Student Learning
2004
The main purpose of this study is to analyse the factorial structure, psychometric properties and predictive capacity for academic achievement of a scale designed to evaluate the time management skills of Spanish high school students. An adaptation of the Time Management Questionnaire was presented to two samples of 350 Spanish high school students. Exploratory and Confirmatory Factor Analysis results from the two samples shows an adequate fit of a three-factor oblique model, as well as its superior explanatory capacity compared to other competitive models considered. This model basically reproduces the structure of the original scale, integrating the subscales on short-range planning, lon…
