Diseño de un instrumento para la identificación del matoneo

Objective: to design an instrument that allows to identify bullying within educational contexts, taking into account the three main actors present in this issue (bully, victim, and observer) and different types of aggression (physical, social and verbal). Colombia does not have validated assessment instruments to identify these aspects adequately. Method: the test consists of 35 items; it was submitted for evaluation by expert judges, and it was later modified and applied to a sample of 300 students of both sexes, aged 9 to 17, belonging to a private school in the municipality of Subachoque in the Cundinamarca department. Results: the instrument was evaluated using reliability and validity criteria, obtaining a suitable statistical support, with a reliability index of .961 using Cronbach's Alpha coefficient. Conclusion: statistical analyses applied to the test indicate that it adequately meets the criteria of reliability and validity.
