Consistencia interna y dimensionalidad del cuestionario breve para detectar intimidación escolar

espanolObjetivo. Corroborar el desempeno psicometrico, la consistencia interna y la dimensionalidad del Cuestionario Breve de Deteccion de Intimidacion Escolar (CBDIE). Metodo. Se diseno un estudio de validacion en el que participaron 350 estudiantes, entre los 10 y los 17 anos (M = 13.3; DE = 1.8), 53.7% de genero femenino. Se calcularon indicadores de consistencia interna (Kuder-Richardson, K-R, y omega de McDonald) para las tres subescalas del CBDIE. Resultados. La subescala de intimidacion percibida mostro K-R de 0.55 y omega de McDonald de 0.58; la subescala de sintomas emocionales, 0.80 y 0.81; y la subescala de intimidacion perpetrada, 0.41 y 0.33. No fue posible demostrar la dimensionalidad del instrumento. Conclusion. Solo la subescala de sintomas emocionales de CBDIE presenta alta consistencia interna. Se necesitan mas investigaciones de la dimensionalidad del CBDIE, para dar cuenta de su estructura interna. EnglishObjective. To corroborate the psychometric performance, internal consistency and dimensionality, of the Brief Questionnaire for Bullying Detection (BQBD). Method. A validation study was designed in which 350 students between 10 and 17 years of age (M = 13.3; SD = 1.8) participated, 53.7% of them female. Internal consistency indicators (Kuder-Richardson, K-R and McDonald’s omega) were calculated for the three sub-scales of the BQBD. Results. The sub-scale of perceived intimidation showed K-R of 0.55 and McDonald’s omega of 0.58; the sub-scale of emotional symptoms were 0.80 and 0.81, and the sub-scale of perpetrated intimidation were 0.41 and 0.33, respectively. It was impossible to demonstrate the proposed dimensionality. Conclusion. Only the sub-scale of emotional symptoms of the BQBD has high internal consistency. More research on the dimensionality of the BQBD is needed to explain its internal structure.
