Friendship is typically assumed to be a protective factor for victims of school bullying, so the possibility of victimization by friends is rarely explored. This study examines the prevalence of positive affiliation between the victims and aggressors in verbal and physical bullying. Peer nomination inventories were used to assess the friendship and dyadic bullying tendency among 237 Taiwanese middle school 7th graders. A total of 1,084 incidents of dyadic verbal bullying and 1,327 incidents of physical bullying were reported by the respondents. Friendship nominations among aggressors and victims could be unilateral (a peer nominates someone who does not in turn nominate them) or reciprocal (both the aggressor and the victim nominate each other as friends). Reciprocal nominations between victims and aggressors occurred in approximately 8% of cases of verbal bullying incidents and about 12% of physical bullying incidents. About 8% of victims of verbal or physical bullying unilaterally nominated the aggressor as a friend, with 9% and 12% of aggressors nominating victims as friends in the two cases. The self-reported strength of friendships was high among the reciprocal friends. Implications for the existence of bullying within friendship dyads for research and practice are discussed.
