Indicators of aggression: The dissipation-rumination scale

Discussion on results of recent studies on Irritability and Emotional Susceptibility scales introduces the presentation of a new scale to study individual differences related to aggressive behavior. The new Dissipation-Rumination Scale results from examining the influence of the interval of time between the instigation and the opportunity to aggress and is related to the inclination to overcome and abandon more or less rapidly feelings of distress and wishes of retaliation associated with the experience of insults suffered. While principal-components analysis confirms the unifactorial structure of the scale with respect to groups of Ss of different language and nationality, results of experimental studies clarify its construct validity.
