Sibling Bullying in Turkish Adolescents: Translation and Cross-Cultural Validation of the Sibling Bullying Questionnaire

Abstract

Purpose: The primary aim of this study was to translate the Sibling Bullying Questionnaire (SBQ) into Turkish and validate it. A secondary aim was to estimate the prevalence of sibling bullying in Turkish adolescents. Methods: The SBQ was forward and backwards translated by a team of English-Turkish bilinguals. Following this, self-report data were collected from Turkish adolescents (N=301) aged 10 to 18 years old (mean age=14.25 years, SD=2.46). Confirmatory factor analysis (CFA) was used to confirm the factor structure of the newly translated Turkish SBQ (T-SBQ). Descriptive analyses were then conducted to report the characteristics of the sample and the prevalence of sibling bullying. Results: CFA confirmed the original two-factor structure of the T-SBQ indicating that a first-order correlated two-factor (victimisation and perpetration) model show the best model fit: x2=160.33 (p <.001), df=61, RMSEA=.07, CFI=.95 and TLI=.93. The T-SBQ also showed satisfactory levels of internal consistency in victimisation (α=.84) and perpetration (α=.83) subscales with excellent reliability for the overall test scale (α=.90). The convergent validity of the scale was also high as demonstrated by the inter-scale correlation coefficients between the T-SBQ and Revised Sibling Bullying Questionnaire (α=.79). In terms of sibling bullying prevalence, approximately half of the adolescents (51%) reported having been involved in some form of sibling bullying in the preceding six months, either as pure-victim (18%), pure-bully (3%) or bully-victim (30%).Conclusions: The T-SBQ is valid and reliable in measure sibling bullying in Turkish adolescents and sibling bullying is prevalent in the lives of Turkish adolescents.Keywords.

A longitudinal study of sibling bullying and mental health in autistic adolescents: The role of self‐esteem

“…This well aligns with a recent report, as Toseeb, McChesney, Dantchev, and Wolke (2020) have also found that White adolescents are at increased risk of being a victim (i.e., victim‐only) but not a perpetrator (i.e., bully‐only) of sibling bullying. Perhaps, this may be because non‐White families are more inclined to protect their autistic child during sibling conflict and bullying situations than White families (Deniz, Asbury, & Toseeb, 2023).…”
