The cyberbully/victim scale allows determining whether they are subjected to a cyberbullying and/or victimization and if so, what kind of a bullying they are exposed or applied. The Internet Parenting Scale allows, such as laissez-faire/authoritarian/authoritative/permissive attitudes, to assess how parents approach to adolescents internet usage. Family Evaluation Scale enables assessment of successes and failures of family func-tions in problem solving, communication, roles, emotional reaction capability, capacity of showing interest, behavior control, general functions areas. 386 adolescents, between the ages of 12-14 (6th-8th grades) were taken to study.

Cyberbullying and/or victimization is found significantly related to disciplinary punishment, threatening/to be threatened, involving in a fight, smoking-alcohol consumption, internet/ mobile phone usage, and psychiatric treatment. The attitudes of families towards internet usage of adolescents and family functioning are also found related to cyberbullying and/or victimization.
