Over the last two decades, cyberbullying has gained increasing attention from the research community as the phenomenon has become a public health issue affecting children, adolescents, and young adults. Although several instruments assess cyberbullying worldwide, many still need to be adequately validated in different languages, countries, and cultures. The European Cyberbullying Intervention Project Questionnaire (ECIPQ) is one instrument that aims to measure two dimensions of cyberbullying: cyber-victimization and cyber-aggression. Although the instrument has been translated into various languages and validated in several European and non-European countries, validation studies have yet to be conducted in Turkish culture. This study aimed to adapt the ECIPQ into Turkish and to investigate the psychometric quality of the instrument in Turkish population. A total sample of 632 college students participated in the study. Along with the ECIPQ, the Buss-Perry Aggression Questionnaire, the Rosenberg Self-Esteem Scale, and the Satisfaction with Life Scale were administered for validation purposes. The results showed that the Turkish version of the ECIPQ had sufficient internal consistency. The confirmatory factor analysis supported the two-factor structure of the ECIPQ. The ECIPQ showed adequate convergent validity, as evidenced by the positive correlation between the cyberbullying and aggression scores and the negative correlation between cyberbullying and self-esteem scores. In conclusion, the ECIPQ can be considered a psychometrically sound measure to assess Turkish college students' perceived cyber-aggression and cyber-victimization levels.
