Purpose In this study, the cyber aggression in relationships scale (CARS) was intended to be adapted to Turkish. Design and Methods The study was designed as a methodological study with 426 students. Findings The best fit index values for both the cyber perpetration and cyber victimization scales (CVSs) were obtained through confirmatory factor analysis. Cronbach's alpha internal consistency coefficients for the overall and sub-dimensions of the cyber perpetration scale and CVS were found to range from 0.88 to 0.92 and 0.85 to 0.91, respectively. Practice Implications In the study, CARS was found to be a valid and reliable instrument for Turkish society.
