Objectives: The aim of the research is to examine whether there is a higher prevalence of experiencing violence via the Internet in adolescents with a psychiatric disorder compared to adolescents who do not have a psychiatric diagnosis. Materials and methods: A total of 102 respondents participated in the research. Test group consisted of adolescents who came to the outpatient clinic for child and adolescent psychiatry, KBC Split, in the period from April 1 to May 31, 2023, for psychiatric examination or treatment. The second group is the control group, consisting of adolescents attending the fifth to eighth grade of elementary school and the first to fourth grade of high school. Students from Ivan Mažuranić elementary school, Obrovac Sinjski, and the Tourist and Hospitality School, Split, participated with the consent of their parents. The exclusion criterion for the control group is visiting a psychologist or psychiatrist. A questionnaire on violence over the Internet was conducted. The translated Spanish version of the European Cyberbullying Intervention Project Questionnaire was used (ECIP-Q). The questionnaire consists of eleven questions related to different types of online violence, and the individual answers on a scale from zero to four regarding the frequency of exposure to violence, where zero means never, and four means more than once a week. It covers a period of two months prior the moment of solving the questionnaire. Results: Adolescents with psychiatric disorders, such as anxiety and depressive disorders, and those who exhibit self-injurious behavior, experience significantly more violence via the Internet. Violence is defined as suffering some form of online abuse once a month or more often. This was stated by 66.67% of subjects with the disorder, compared to 25.49% of subjects without the disorder (P<0,001). Conclusions: There is a need for more research on internet violence among adolescents with psychiatric disorders, given that victimization among them is significantly higher than among adolescents from the general population.
