Objective: The aim of this study was to perform validity and reliability studies for adapting the Cyber Bullying Scale (SBS), which consists of 15 cyberbullying behaviors and three sub-dimensions, to Turkish culture. Methods: This research was carried out in two stages. In the first stage, the scale was translated into Turkish, exploratory factor analysis for validity, internal consistency coefficient, test-retest and item analysis methods were used for reliability. In the second stage, confirmatory factor analysis and compliance validity studies were conducted for the validity of the scale. The first and second stages, respectively, 300 and 339 participants took part in the study. Results: As a result of exploratory factor analysis conducted in the first stage, approximately 48% of the total variance of the scale was explained. Item factor loads in the scale ranged from 0.42 to 0.78. For the reliability of the scale, internal consistency coefficient was calculated as 0.94, 0.90, 0.88, and 0.93 for the total, bullying, victimization and witness-ing subscales. The test-retest reliability coefficient was 0.94, 0.90, 0.88, and 0.87 for the scale total, bullying, victimization and witness subscales. As a result of confirmatory factor analysis conducted in the second stage, it can be said that the scale has a good level of goodness of fit (χ2=2830.18, sd=807, χ2/sd=3.51, RMSEA=0.08, RMR=0.02, SRMR=0.06, GFI=0.91, AGFI=0.90, CFI=0.97, NNFI=0.97, IFI=0.97). Conclusions: As a result of all he procedures, it can be said that the form of Cyber Bullying Scale adapted to Turkish culture is valid and reliable. [Anadolu Psikiyatri Derg 2020; 21(0.100): 39-47]
