Establishing a web-based measurement of aggression (WTCRTT): Examining the validity of a modified Taylor’s competitive reaction time test

The current study attempted to develop a web-based state aggression measurement program (WTCRTT) and examine its applicability in terms of validity and reliability by conducting laboratory experiments. A repeated experimental design was employed, where subjects were exposed to both violent and non-violent media content. A physiological measure was also included to test the internal validity of media stimulation. The results showed the WTCRTT is a valid measure of behavioral aggression as the hypotheses on construct validity and internal validity were supported. For instance, the WTRCTT after exposure to violent media was positively correlated to anger, physical aggression, and total trait aggression scores. The WCRTT that was developed and tested in this study can be used not only by the scholars interested in aggression research with no cost and but also by the parents who want to monitor their children’s state (i.e., behavioral) aggression.
