CERVANTES BOTERO, Víctor H; CEPEDA CUERVO, Edilberto  and  CORRALES BOSSIO, Martha. Analysis of a School Bullying Questionnaire Using Item Response Theory and Multiple Correspondence Analysis. Univ. Psychol. [online]. 2014, vol.13, n.2, pp.443-456. ISSN 1657-9267.  https://doi.org/10.11144/Javeriana.UPSY13-2.aaed.

This study presents reanalyzes of Cepeda et al. (2008)'s data using an Item Response Theory (IRT) model and Multiple Correspondence Analysis (MCA). Both internal consistency (α = 0.96) and fit to the unidimensionality assumption (per parallel analysis) were found to be satisfactory. Coincidences between both analyses are shown. The percentage of students affected by bullying in the sample is similar to that found in other studies in Colombia. Finally, the questionnaire appears to be a valid and reliable measure of bullying.

Keywords : Bullying; bullying assessment; Item Response Theory; scale anchoring; cluster analysis.
