Propiedades psicométricas del European Bullying Intervention Project Questionnaire (EBIPQ) y el European Cyberbullying Intervention Project Questionnaire (ECIPQ) en una muestra de adolescentes del Ecuador

Introduction: School bullying has sparked considerable research interest, leading to the development of specific measures aimed at assessing both traditional bullying and cyberbullying (CB). Objective: To identify evidence of validity for the European Bullying Intervention Project Questionnaire (EBIPQ) and the European Cyberbullying Intervention Project Questionnaire (ECIPQ) in a sample of Ecuadorian adolescents. Method: A cross-sectional descriptive and psychometric study analyzing the construct validity, internal consistency, and convergent validity of both instruments. Sample: 341 adolescent students (56% female, 44% male), aged 14 to 19 years (M = 15.72; SD = 0.85), from different cities in Ecuador. Results: Oblique fit models with two dimensions per instrument provide the best factor representation. They also demonstrate adequate internal consistency across their dimensions and a high correlation between the two questionnaires. Conclusion: The EBIPQ and ECIPQ prove to be valid, reliable, and relevant instruments for measuring bullying and cyberbullying among adolescents in Ecuador.
