Demographic profile of each participant (age, sex, high school level) are included in the questionnaire. The questionnaire was administered per year level by the researcher during the homeroom period and took 15 minutes to be answered by the subjects. Exclusion criteria included those who were not able to complete answering the questionnaires and were absent during the time of administration of the questionnaire. 31 subjects were excluded only because they did not answer completely the questionnaires. Descriptive analysis of the prevalence of bullying in general and cyberbullying specifically and frequency of subjects as victims according to the subtypes of cyberbullying were done. Analysis of impact of various subtypes of cyberbullying using 2-way ANOVA at p=0.5 and 95% level of confidence was done by assigning values to the severity respondents believed each subtype of cyberbullying has on the victim compared to traditional bullying (less harmful = -1; the same = 0; more harmful = +1). The more positive score means that the impact of this form of cyberbullying is seen as high, a negative score as low.

For all types of cyberbullying, first year level has the most number of victims and fourth year having the least.
