We analyse the consequences of experiencing bullying victimization in junior high school, using data on a cohort of English adolescents. The data contain self-reports of five types of bullying and their frequency, for three waves, when the pupils were aged 13–16 years. We assess the effects of bullying victimization on short- and long-term outcomes, including educational achievements, income and mental ill-health at age 25 years using a variety of estimation strategies – least squares, matching and inverse probability weighting. The detailed longitudinal data, linked to administrative records, allows us to control for many of the determinants of child outcomes that have been explored in previous literature, and we employ comprehensive sensitivity analyses to assess the potential role of unobserved variables. The pattern of results suggests that there are quantitatively important detrimental effects on victims. We find that both type of bullying and its intensity matter for high-stakes outcomes at 16 years, and for long-term outcomes at 25 such as mental health and income.

青少年学校欺凌受害和以后的生活结果

我们使用一组英国青少年的数据分析了在初中经历欺凌受害的后果。当学生年龄在 13-16 岁时，数据包含五种类型的欺凌及其频率的自我报告，分三波。我们使用各种估计策略（最小二乘法、匹配和逆概率加权）评估欺凌受害对短期和长期结果的影响，包括 25 岁时的教育成就、收入和心理健康状况。与行政记录相关的详细纵向数据使我们能够控制先前文献中探讨的许多儿童结果的决定因素，并且我们采用综合敏感性分析来评估未观察到的变量的潜在作用。结果模式表明，对受害者有数量上重要的不利影响。我们发现，欺凌的类型及其强度对 16 岁时的高风险结果和 25 岁时的长期结果（如心理健康和收入）都很重要。
