METHOD: After translating all 39 items of the questionnaire into Bangla, it was administered on 206 children, aged 3 to 6 years, recruited randomly from ten preschools in Dhaka. The schools were selected randomly from the official list of preschools prepared by the Dhaka City Corporation. Class teachers of the respective children completed the questionnaire with the assistant of research assistants.
RESULTS: The Bangla version of the questionnaire retained all 39 items, with seven factors as they were in the English version. The Bangla version shows sufficient reliability (Cronbach's alpha = 0.87; test-retest reliability = 0.89 for whole questionnaire and .79-.89 for sub-scales; inter-rater reliability = 0.88 for whole questionnaire and .79-.88 for sub-scales), and validity (correlated positively with the English version; r = 0.85).
CONCLUSION: Due to its robust psychometric properties, the Bangla DMQ-18 is suggested to be used for Bangladeshi preschool children to assess their mastery motivation.
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.
