The use of different modes of inquiry about interpersonal violence experiences may result in different frequency estimates. Thus, we measured the frequency and identified the factors associated with cyberbullying among urban school-going adolescents using different tools. Participants were enrolled at the four largest public schools in Porto for seventh- to 12th-grade students and were evaluated during the 2014-2015 academic year. We studied 2,624 adolescents (1,186 males and 1,438 females), 60% of all eligible students. Information under anonymity was collected at the school premises, using a self-administered questionnaire that comprised information on sociodemographic characteristics, school life, emotional well-being, the Internet use monitoring and cyberbullying experiences. Cyberbullying was assessed with two general questions ("Have you ever been a victim of cyberbullying?" and "In the last 12 months, have you been a victim of cyberbullying?) and using the from the Centers for Disease Control and Prevention (CDC) that covers the last 30 days experience. The lifetime prevalence of cybervictimization was 7.6% and for the last 12 months 3.9%, similar in boys and girls, while the prevalence in the last 30 days was 38.2%, significantly higher in girls (43.1% vs. 33.3%). A statistically significant association of cybervictimization with negative emotional well-being and school bullying victimization experience was identified regardless of timing and the mode of ascertaining cyberbullying. Different measurement instruments resulted in different estimates of the prevalence of cyberbullying. Regardless of the instrument used, a strong association of cyberbullying involvement with negative emotional well-being in adolescents was observed.
使用不同的方法来调查人际暴力经历可能会导致不同的频率估计。因此，我们使用不同的工具来衡量频率，并确定与城市学校青少年网络欺凌相关的因素。参与者是在波尔图的四所最大的公立学校招募的，他们是 7 到 12 年级的学生，并在 2014-2015 学年期间进行了评估。我们研究了 2624 名青少年（男生 1186 名，女生 1438 名），占所有符合条件学生的 60%。在学校场所，匿名收集信息，使用自填式问卷，包括社会人口特征、学校生活、情绪健康、互联网使用监测和网络欺凌经历。网络欺凌使用两个一般问题进行评估（“你曾经是网络欺凌的受害者吗？”和“在过去 12 个月里，你是网络欺凌的受害者吗？”），并使用疾病控制和预防中心（CDC）的问题，涵盖过去 30 天的经历。网络欺凌的终生患病率为 7.6%，过去 12 个月为 3.9%，在男孩和女孩中相似，而过去 30 天的患病率为 38.2%，在女孩中显著更高（43.1%比 33.3%）。无论时间和确定网络欺凌的模式如何，网络欺凌的发生与负面情绪健康和学校欺凌受害经历都有统计学上的显著关联。无论使用哪种工具，网络欺凌的发生与青少年负面情绪健康之间都存在很强的关联。
