Validez y confiabilidad del 'Cuestionario de calidad de vida KIDSCREEN-27' versión padres, en Medellín, Colombia

OBJECTIVE Validate the KIDSCREEN-27 for parents in the metropolitan area of Medellín, Colombia, including the Social Acceptance (SA) subscale of KIDSCREEN-52, as it evaluates the effect of bullying in Life Quality of children. METHODS The study population was made up by parents of children between 8 and 18, from Medellín and its metropolitan area. A sample of 1,150 parents was estimated according to the different psychometric properties to be measured. Construct validation was made by comparing the mean scores between groups of high and low socioeconomic conditions. The content validity and the measurement of reliability were verified by internal consistency and test-retest stability. The parent-child agreement was also measured. RESULTS The internal consistency was adequate (Cronbach alpha 0,76-0,83). Parents of children with better socio-economic status had higher scores in all dimensions (p<0,05). Scores were higher among healthy children. Women had lower scores than men, while children registered higher scores than adolescents. The intraclass correlation coefficient for the reliability assessment was above 0.7 in all dimensions, except in School Environment-SE- (ICC 0,6-0,92). The parent-child agreement reached moderate and good levels (ICC 0,49-0,69). The exploratory factorial analysis, including social acceptance subscale, registered eight dimensions, four of which in agreement with the original questionnaire: Physical activity, SE, Social Support, and SA subscale. CONCLUSIONS KIDSCREEN-27 for parents is a valid and reliable instrument to be used in the Colombian context.Objective Validate the KIDSCREEN-27 for parents in the metropolitan area of Medellin, Colombia, including the Social Acceptance (SA) subscale of KIDSCREEN-52, as it evaluates the effect of bullying in Life Quality of children.

Artículo originalValidación por modelo de Rasch del Cuestionario de Calidad de Vida (PedsQL 4.0®) en niños y adolescentes colombianosRasch Model in the Validation of the Paediatric Quality of Life Inventory™ 4.0 (PedsQL 4.0™) in Colombian Children and Adolescents

INTRODUCTION The aim of this study was to validate the PedsQL 4.0™ in Colombian children and adolescents using the Rasch model. The Paediatric Quality of Life Inventory (PedsQL 4.0™) has demonstrated to be a reliable and sensitive measurement to changes in health status, as well as being quick and easy to use. METHODS Validation study of measurement tools. The PedsQL 4.0™ was applied to a convenience sample of 375 children and adolescents between 5 and 17 years old and 500 caregivers of children between 2 and 18 years old in five Colombian cities. The psychometric properties were analysed according to the Rasch model, including adjustment, separation, and differential item functioning (DIF). RESULTS The Rasch model provided adequate fits to data. The social dimension, for both versions, had greater difficulty than the physical health dimension. Internal consistency for the items was observed, while for individuals, the values of reliability and separation were lower than that established. The DIF occurred in very few variables, especially when comparing cities. The characteristic curves for the items presented disordered thresholds. CONCLUSIONS The items had adequate internal consistency. Analysis showed adequate individual separation, but disordered thresholds were found in the response categories. No DIF was observed by sex or disease, but it is noteworthy that the DIF occurred between cities.

Medición del bullying escolar: Inventario de instrumentos disponibles en idioma español

Se realizo una revision de literatura para identificar articulos sobre cuestionarios de medicion de bullying existentes en idioma espanol, que tuvieran informacion del contenido del instrumento, reportaran las propiedades psicometricas y que la poblacion objetivo fueran estudiantes. Se encontraron 36 instrumentos, de ellos 21 reportaban alguna medida psicometrica y 15 cumplieron los criterios de inclusion. Tres de los doce instrumentos se crearon en ingles y fueron posteriormente adaptados al espanol. Siete instrumentos informaron solo el alfa de Cronbach, 7 la consistencia interna y uno ambas caracteristicas. El numero de items de los cuestionarios vario entre 15 y 70 y la edad de administracion entre 7 y 20 anos. Las dimensiones incluidas fueron: comportamientos violentos, agresion, ira, ocurrencia de violencia, intimidacion, identificacion de actores, presencia de ansiedad y estres. La evidencia muestra que la mayoria de los cuestionarios se elaboraron a partir de otros cuestionarios de bullying y que poseen adecuadas propiedades psicometricas.
