Cyberbullying and School Bullying Are Related to Additive Adverse Effects among Adolescents

Abstract

<b><i>Introduction:</i></b> The aim of this study was to examine whether (a) cyberbullying has unique associations with mental health problems, risk-taking, and self-harm behavior in victims and perpetrators when compared to school bullying and (b) if cyberbullying is associated with an additional burden for students already involved in school bullying. <b><i>Methods:</i></b> Data were collected from 6,561 students across 23 schools in Germany (grades 5–13). The sample was divided into the following four groups: cyber-only involvement (victims = 1.9%, perpetrators = 0.6%), school-only involvement (victims = 17.2%, perpetrators = 11.9%), dual involvement (victims = 5.7%, perpetrators = 2.9%), and noninvolvement (victims = 75.3%, perpetrators = 84.6%). Multilevel mixed-effects regression analysis was conducted to examine group differences in mental health (Strengths and Difficulties Questionnaire, KIDSCREEN-10), risk-taking, and self-harm behavior (e.g., substance use, suicide attempts). <b><i>Results:</i></b> Cyber-only bullying had unique associations with mental health problems and risk-taking behavior in victims (lower levels of peer relationship problems: <i>p</i> &#x3c; 0.001, greater substance use: <i>p</i> &#x3c; 0.05) and perpetrators (higher levels of peer relationship problems: <i>p</i> &#x3c; 0.05) when compared to school-only bullying. Dual victims and perpetrators reported significantly more mental health problems (victims: χ²₍₅₎ = 221.58, <i>p</i> &#x3c; 0.001; perpetrators: χ²₍₅₎ = 116.40, <i>p</i> &#x3c; 0.001) and were more likely to report risk-taking and self-harm behavior (victims: χ²₍₇₎ = 115.15, <i>p</i> &#x3c; 0.001; perpetrators: χ²₍₇₎ = 38.79, <i>p</i> &#x3c; 0.001) than students involved in school-only bullying. <b><i>Conclusion:</i></b> Cyber-only bullying appears to be related to specific mental health issues beyond those associated with school-only bullying. Cyberbullying and school bullying go along with additive mental health problems, risk-taking, and self-harm behavior in both victims and perpetrators. Thus, bullying prevention and intervention programs should also target cyberbullying.
