Background/Objective: Despite the great interest that bullying and cyberbullying have received during the last decades, the problem of defining these phenomena is still debated. Recently, this discussion has also been articulated in terms of how young people who are directly involved in bullying and cyberbullying understand these notions. This study aimed at investigating the operational definitions of both bullying and cyberbullying provided by adolescent victims and perpetrators, by inquiring the weight of traditional criteria (i.e., frequency, deliberateness, imbalance of power, and harm) as well as dominance in the perception of these phenomena. Method: A total of 899 students aged between 11 and 16 years filled out the Student Aggression and Victimisation Questionnaire. Results: Common traits and differences between the operational definition of bullying and cyberbullying and between the perspectives of victims and perpetrators of aggression were found. The most relevant criterion for the perception of both these phenomena was clearly the presence of dominance. By contrast, the imbalance of power showed no significant relationship with the perception of being bullied or bullying others both offline and online. Conclusions: Findings emphasise that young people conceptualise bullying with a clear reference to relational and group processes, rather than to individual differences.

背景/目的：尽管在过去的几十年中，欺凌和网络欺凌引起了极大的兴趣，但定义这些现象的问题仍在争论中。最近，还通过直接参与欺凌和网络欺凌的年轻人如何理解这些概念来阐明这一讨论。这项研究旨在通过询问传统标准的重要性（即频率，故意性，权力失衡和伤害）以及对这些现象的主导地位，调查青少年受害人和犯罪者提供的欺凌和网络欺凌的操作定义。现象。方法：共有899名11至16岁的学生填写了《学生侵略和被害调查表》。结果：发现了欺凌和网络欺凌的操作定义之间以及攻击的受害者和作案者之间的共同特征和差异。对于这两种现象的感知，最相关的标准显然是统治力的存在。相比之下，权力的不平衡与被离线或在线欺凌或欺凌他人的感觉没有显着关系。结论：调查结果强调，年轻人将欺凌概念化，并明确提及关系和群体过程，而不是个人差异。
