These changes have sparked concerns about potential increases in cyberbullying and its associated risks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study aims to explore how factors such as age, exposure to violent media, parental communication quality, internet access, sex, and sibling relationships influence cyberbullying behavior at school.

Exposure to violent media increased both cyberbullying perpetration and victimization, but the effect on perpetration decreased during the COVID-19 pandemic. The well-established correlation between internet access and both cyberbullying perpetration and victimization remained unaffected by COVID-19. Surprisingly, adolescents with siblings were less likely to become victims or perpetrators of school-related cyberbullying, irrespective of the pandemic.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In hindsight, COVID-19, functioning as a kind of natural experiment, has provided us with a unique opportunity to examine the effects of a global event, forcing major behavioral changes on the persistent challenge of cyberbullying in middle schools.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/70508","type":"journal-article","created":{"date-parts":[[2025,1,10]],"date-time":"2025-01-10T03:24:18Z","timestamp":1736479458000},"page":"e70508","source":"Crossref","is-referenced-by-count":13,"title":["Adolescent Cyberbullying and Cyber Victimization: Longitudinal Study Before and During COVID-19"],"prefix":"10.2196","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4281-489X","authenticated-orcid":false,"given":"Peter Johannes","family":"Schulz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1527-9652","authenticated-orcid":false,"given":"Marc-Olivier","family":"Boldi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8710-9193","authenticated-orcid":false,"given":"Ann","family":"van Ackere","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,3,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/ab.21986"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.copsyc.2023.101689"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2021.02.049"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2020.106341"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1080\/01639620701457816"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/s2215-0366(15)00223-0"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2016.12.026"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.2196\/45563"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1177\/0886260513506277"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1007\/s11218-015-9318-6"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/s2352-4642(20)30186-3"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2022.1090047"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1177\/15248380231171185"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1177\/1461444816634037"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.tele.2020.101362"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1037\/a0030309"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1111\/josh.12290"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1080\/15388220.2022.2075881"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1177\/1524838019888555"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1093\/jcmc\/zmz031"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2021.634909"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2009.11.014"},{"key":"ref23","author":"Kowalski, RML","year":"2012","journal-title":"Patricia.
