This research aims at revising the Victim Scale of the School Bullying Scales to examine bullying behaviors with high frequency and high severity. Participants were 1611 secondary school students in Kaohsiung. The Rasch Rating Scale Model was employed to analyze the collected data. Results showed that the revised Victim Scale fit well, exhibiting good evidence of the construct validity. Male students considered that victimized behaviors with high frequency and high severity were ¡§friendship being breached,¡¨ ¡§belongings being taken without permission,¡¨ ¡§goods being breached,¡¨ ¡§being tattled,¡¨ ¡§being hit or kicked,¡¨ and ¡§being neglected intentionally. Female students revealed different patterns of bullying behavior, while female students regard ¡§friendship being breached,¡¨ ¡§being crowded out of a group,¡¨ ¡§being isolation,¡¨ ¡§belongings being taken without permission,¡¨ ¡§being tattled,¡¨ ¡§being criticized online,¡¨ ¡§being neglected intentionally¡¨ and ¡§others kept silent to me on purpose¡¨ as victimized behaviors with high frequency and high severity. Finally, the implications for school bullying intervention and prevention were discussed. Keywords: school bullying, Rasch measurement, multidimensional Rasch analysis, DIF
