Background: The assessment of bullying-related attributes is vital in developing anti-bullying intervention and prevention programs. The revised Olweus Bully/Victim Questionnaire (OBVQ-R) is one tool that has been widely used for this purpose. Thus, as we noticed a rising interest in research on bullying and there is a scarcity of proper psychometric tools to assess bullying-related attributes in Bangladesh, our study aimed to translate the OBVQ-R and test the psychometric properties of the Bangla version of this questionnaire on a large Bangladeshi adolescent sample.
Method: In Bangladesh, we collected data from grade 8-10 students (N = 567, 309 females, 258 males, AgeMean±SD=15.12 ± 0.81). The participants completed Bangla OBVQ-R, Beck Youth Inventory (BYI), and Children's Revised Impact of Events Scale-13 (CRIES-13).
Results: The item response theory (IRT) analysis discarded five items and retained 15 items (Victimization=8, Perpetration=7). Both subscales had items with high discrimination (Victimization: 3.14 ± 0.67; Perpetration: 3.40 ± 1.04). Confirmatory factor analysis supported a correlated two-factor model (CFI=0.99; TLI=0.99). Both subscales (Victimization and Perpetration) and the 15-item full scale exhibited satisfactory reliability (>0.80). In line with our predictions, both subscales demonstrated significant positive correlations with BYI and CRIES-13, indicating satisfactory concurrent validity.
Conclusion: The results of the psychometric analyses supported the reliability and validity of the 15-item Bangla-version OBVQ-R to assess bullying involvement. Hence, this new, adapted measurement can facilitate further bullying research in Bangladesh and, thus, the development of prevention and intervention programs.
