The Novaco Anger Scale is the only scale published that allows for the measurement of anger with relation to Novaco's (1976) widely used model of anger management. This paper is the first to present a statistical analysis of the factor structure of this scale. From a sample of healthcare employees and outpatients with problems with anger control, a factor solution was identified. It is suggested that the items loading on this scale contribute to valid assessment of anger. The implications for the use of the NAS are considered.
