“…On the whole, this study was the first to validate RBEQ and examine retrospective bullying experiences in Iranian students. The results showed that, meanwhile RBEQ has a single‐factor structure, and only same‐sex bullying occurs in Iranian schools, however, due to the consistency of the findings of the present study with the findings of studies in other cultures regarding normalization of bullying by students (Connell et al, 2019; Parada & Craven, 2002; Runions et al, 2019), high prevalence of reporting bystander role compared to victim or perpetrator roles (Tłuściak‐Deliowska, 2015, 2016), low percentage of reporting bullying perpetration by students (Rivers et al, 2009), high prevalence of bullying incidents in middle school (Rambaran et al, 2020; Salmivalli & Peets, 2018), the stability of different bullying roles over time (Farmer et al, 2011; Tłuściak‐Deliowska, 2015), positive correlation between different bullying roles (Dragone et al, 2020; Walters, 2020), and reliability of RBEQ (Tłuściak‐Deliowska, 2015, 2016), It can be confirmed that RBEQ is a valid and satisfactory questionnaire that can be utilized to determine levels of retrospective bullying experiences of individuals over 18 years of age, in different cultures.…”
