Psychometric validation of the audio-guided rBVQ instrument for bullying evaluation among students.

The revised Olweus Bully/Victim Questionnaire (rBVQ) is an internationally used instrument to identify bullying, but due to Brazilian students' low proficiency in reading and writing, it had to be adapted for audio-guided use through smartphones. We investigated construct validity, using Confirmatory Factor Analysis (CFA), under a two-correlated factor solution. Participated 1,742 fifth graders and 2,316 seventh graders from 30 public schools in the city of São Paulo. We found excellent fit indices models for both grades (fifth grade: CFI=0.985, RMSEA=0.020; seventh grade: CFI=0.990, RMSEA=0.015), as well as factor loading higher than 0.4 for all items, indicating their relevance to the construct. The rBVQ demonstrated excellent psychometric properties and may help future studies that aim to investigate bullying in populations with similar profiles. In addition, this study innovates by evaluating an audio-guided instrument and using mobile technology. [ABSTRACT FROM AUTHOR]
