Development and Validation of a Brief Version of the European Bullying and Cyberbullying Intervention Project Questionnaires (EBIP-Q and ECIP-Q).

Abstract

In order to prevent school bullying and cyberbullying, brief measurement instruments with adequate psychometric properties are required. The objective of this study was to develop a combined reduced version of the European Bullying Intervention Project Questionnaire (EBIP-Q) and the European Cyberbullying Intervention Project Questionnaire (ECIP-Q) for its use in the screening of bullying-related behaviors at school. The sample consisted of 1777 students, between 14 and 18 years of age (M = 15.71; SD = 1.26), of which 54.1% were female. The resulting reduced version presents adequate psychometric properties with reliability coefficients between ω = .72 and ω = .82. Factor analyses indicate that both bullying and cyberbullying are structured around two factors: victimization and aggression. The correlations between the scores of the original version and the reduced version were adequate. Bullying and cyberbullying was associated with different indicators of socioemotional adjustment. The European Bullying and Cyberbullying Intervention Project Questionnaire Brief version (EBCIP-QB) seems to be brief, useful, and have adequate psychometric properties for the assessment of bullying and cyberbullying in Spanish adolescents.
