Abstract
The purposes of the present study were to develop an Aggressive Behavior Scale (ABS) to measure self-reported overt aggressive behavior, and to investigate the reliability and validity of the scale. In Study 1, the Aggressive Behavior Scale was developed with a sample of 372 undergraduate students, and its internal consistency was examined. The results suggested that the Aggressive Behavior Scale, which includes 17 items, consisted of 3 factors: physical aggression, verbal aggression, and indirect aggression. In addition, the internal consistency of the Aggressive Behavior Scale was adequate. In Study 2, 406 undergraduate students took the Aggressive Behavior Scale and an Anger Expression Scale. Using those data, the validity of the Aggressive Behavior Scale was examined. The results indicate that the Aggressive Behavior Scale has good cross-validity and acceptable construct validity. Overall, the results of the present study suggest that the Aggressive Behavior Scale provides a reliable and valid assessment of aggressive behavior.
