We examine the nature, frequency, degree of violence and prevalence of cyber-bullying using data from a survey of 1,200 secondary and vocational students in Bangkok. The data were analyzed by using descriptive statistics. The results showed a considerable degree of cyberbullying among Thai youth. More than half had ever seen or heard of cyber-bullying occurring to their friends. About 11.0% of students had seen or heard online fights using electronic messages with angry and vulgar language more than 6 times per month. The potential relationship between cyber-bullying and duration of using the internet, family relationships, experience of violence in the family and family income is also examined.engMahidol UniversityCyber-bullyingFamily contextIndividual characteristicsSecondary studentsVocational studentsArticleInstitute for population and social research
