In this study, we examined the psychometric properties of the Cyberbullying Inventory (CBI) for University Students. There were 635 Turkish university students (57.48% females) in the pilot data set. The results showed that the pilot data set confirmed the proposed factor structure for CBI for University Students with some modifications. The final form of CBI for University Students was cross-validated with a second data set, composed of 1281 Turkish university students (52.54% females). Confirmatory factor analyses revealed adequate fit to the data, the internal consistency coefficients showed good internal consistencies, and evidence for convergent validity was obtained. Therefore, CBI for University Students with 11 items is a valid and reliable assessment instrument that can be used by researchers, counsellors and other mental health practitioners.
