The purpose of the present study is to test the psychometric properties of the Novaco Anger Scale-Provocation Inventory(NAS-PI). A total of one thousand nine hundred and fifty-four children, adolescents, adults, and older adults completed the NAS and the PI. The 44-item NAS and the 25-item PI display acceptable internal reliability; and good fit to three-factor model (cognition, arousal, behavior) and five-factor model (disrespectful treatment, unfairness, frustration, annoying traits of others, irritations), respectively. Moreover, the 12-item cognition scale, the 16-item arousal scale, and the 16-item behavior scale in the NAS, show good fit to three-factor model (justification, rumination, hostile attitude), four-factor model (intensity, duration, somatic tension, irritability), and four-factor model (impulsive reaction, verbal aggression, physical confrontation, indirect expression), respectively. This scale could be used to measure anger multidimensionally and effectively manage it in Koreans.
