This study investigated the association between gender role attitudes, perceived friend support, and school bullying among male adolescents from 11 schools in two cities in China. A total of 3172 Chinese adolescents between 12 and 20 years of age (48.80% girls and 51.20% boys) completed questionnaires that included measures of bullying, gender role attitudes, and perceived social support. In terms of outcome measures, the Chinese version of the Illinois Bully Scale (IBS), Attitudes toward Women Scale for Adolescents (AWSA), and Multidimensional Scale of Perceived Social Support (MSPSS) were used to assess bullying perpetration, gender role attitudes, and perceived friend support, respectively. Based on masculinity theories and the stress-buffering theory, the study found that male adolescents held more traditional gender role attitudes (t = 30.78, p < 0.001) and reported higher prevalence of bullying behaviors (36.02%) than girls (31.20%). In addition, boys��� bullying behaviors were significantly predicted by gender role attitudes through perceived friend support. That is, male youth with more conservative gender role attitudes reported less perceived friend support (adjusted OR = 1.055; SE = 0.013), which elevated their risks of bullying perpetration (adjusted OR = 2.082; SE = 0.302). These findings have critical implications for bullying intervention and prevention through gender equity education.
