The present study examines the role of violence tendecy on cyberbullying perpetrations and their victims. Turkish adolescents [N = 286,167 girls (58,4%) and 119 boys (41,6%)] aged 15-18 years [mean age of 17.6 years (df:0.78)] were recruited from different high school types [101 (35.4%) of the participants were students in vocational high school, 88 (30.7%) anatolian high school and 97 (33.9%) public high school]. Participants completed Revised Cyber Bullying Inventory (RCBI, Topcu & Erdur-Baker, 2010) and Violence Tendency Scale (VTS, Haskan & Yildirim, 2012). Collected data were analyzed Pearson correlation coefficients and simple regression. Pearson correlations revealed that violence tendency was positively related to cyberbullying perpetration (r = 0.344, p < 0.01). Also, violence tendency was positively related to cyber victimization (r = 0.242, p < 0.01). Also simple regressions revealed that violence tendency was significant individual predictors both cyberbullying perpetration and cyber victimization. (C) 2016 Elsevier Ltd. All rights reserved.
