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…
Modern health worries and idiopathic environmental intolerance.
2008
Abstract Objective We conducted two studies to test whether modern health worries (MHWs) were associated with central features of a condition called idiopathic environmental intolerance (IEI) and medical care utilization. Methods In Study 1, 474 Internet users completed an Internet-based questionnaire that assessed MHWs, IEI features, and medical care utilization. In Study 2, the diagnostic specificity of MHWs was investigated by comparing the level of MHWs of three diagnostic groups: 46 people with IEI, 38 people with somatoform disorder but without IEI, and 46 people with neither IEI nor somatoform disorder. Results The good psychometric properties of the MHW scale were confirmed. MHWs we…
The UNIPSICO questionnaire: psychometric properties of the scales measuring psychosocial demands
2016
espanolObjetivo. Analizar las propiedades psicometricas de las escalas de la Bateria UNIPSICO que permiten evaluar los factores psicosociales de recursos del contexto de trabajo. Metodos. La muestra estuvo formada por 2564 participantes, 1391 trabajadores de centros de atencion a personas con discapacidad psiquica, y 1173 docentes de secundaria de la Comunidad Valenciana. La recogida de datos se realizo mediante las escalas de la Bateria UNIPSICO que evaluan factores psicosociales de recursos del lugar de trabajo (26 items) que se agrupan en 4 escalas: Disponibilidad de recursos, Apoyo social en el trabajo, Retroinformacion y Autonomia. Se realizaron analisis de items, validez de constructo…
Black German identities
2009
This study examines the reliability and validity of a German version of the Multidimensional Inventory of Black Identity (MIBI) in a sample of 170 Black Germans. The internal consistencies of all subscales are at least moderate. The factorial structure of the MIBI, as assessed by principal component analysis, corresponds to a high degree to the supposed underlying dimensional structure. Construct validity was examined by analyzing (a) the intercorrelations of the MIBI subscales and (b) the correlations of the subscales with external variables. Predictive validity was assessed by analyzing the correlations of three MIBI subscales with the level of intra-racial contact. All but one predictio…
Validity of the Postural Control and Balance for Stroke test.
2007
Background and Purpose. To determine the construct and predictive validity and sensitivity of the sub-scale items for postural changes, sitting balance and standing balance of the Postural Control and Balance for Stroke (PCBS) test over a 90-day follow-up. Method. In the initial phase of stroke the PCBS test scores were compared with values obtained for the Barthel Index (BI) and the four neuropsychological domains most widely studied in the literature: memory; language; visuo-spatial functions; and visual inattention. The ability of the PCBS test at an early stage to predict functional status, as measured by the BI, and tendency to falls at 90 days after stroke was studied. The sensitivity…
Validation of a measure of Service Climate in organizations
2012
El Clima de Servicio resulta crítico en organizaciones del sector servicios. Refleja la importanciaque las organizaciones atribuyen a la calidad del servicio así como los esfuerzos para complacer a los clientes. Considerando el trabajo de Schneider, White y Paul (1998) como punto de partida, este trabajo valida una medida del clima de servicio en español. Para ello se han desarrollado dos estudios de campo. Un total de 120 hoteles, ubicados en España, participaron en la investigación. La muestra estuvo conformada por 508 empleados de hoteles distribuidos en 152 unidades de trabajo. Nuestros resultados confirmaron que la validez de constructo y predictiva son satisfactorias, con cuatro facto…
Validating justice climate and peer justice in a real work setting
2016
In this study we tested the validity of justice climate and peer justice, measured as second-order constructs, in a real work setting. First, we investigated the appropriateness of aggregating first-order facets of justice climate and peer justice to work-unit level of analysis. Second, we examined the construct validity of justice climate and peer justice as two different factor structures. Third, we tested the hierarchical structure of justice climate and peer justice as second-order factors. Finally, we examined the predictive validity of second-order factors justice climate and peer justice within a nomological network composed of reciprocity with the supervisor and reciprocity with cow…
Measuring perceived community support: Factorial structure, longitudinal invariance, and predictive validity of the PCSQ (perceived community support…
2007
Social support from intimate and confiding relationships has received a great deal of attention; however, the study of the community as a relevant source of support has been comparatively lacking. In this article, we present a multidimensional measure of community support (Perceived Community Support Questionnaire, PCSQ). Through exploratory and confirmatory factor analyses on data from three samples of adult population (two-wave panel: sample 1, N = 1009 and sample 2, N = 780; and an independent sample 3, N = 440), results show that community integration, community participation, and use of community organizations are reliable indicators of the underlying construct of perceived community s…
Comparative evaluation of three semi-quantitative radiographic grading techniques for knee osteoarthritis in terms of validity and reproducibility in…
2008
OBJECTIVE: The objective of this work was to compare the measurement properties of three categorical X-ray scoring methods of knee osteoarthritis (OA), both on semiflexed and extended views. METHODS: In data obtained from trials and cohorts, X-rays were graded using Kellgren and Lawrence (KL), the OA Research Society International (OARSI) joint space narrowing score, and measurement of joint space width (JSW). JSW was analyzed as a categorical variable. Construct validity was assessed through logistic regression between X-ray stages and Western Ontario and McMaster Universities OA Index. Inter-observer reliability was assessed in 50 subjects for extended views by weighted kappa. Intra-obser…
