||This new self-report inventory makes it possible, and practical, to routinely screen children and adults for aggressive tendencies. The Aggression Questionnaire (AQ) measures an individual’s aggressive responses and his or her ability to channel those responses in a safe, constructive manner. The AQ can be administered quickly to large numbers of people. The AQ is a full revision of the Buss-Durkee Hostility Inventory, a long-time standard for assessing anger and aggression. It consists of just 34 items, scored on the following scales: Physical Aggression; Hostility; Verbal Aggression; Indirect Aggression; and Anger. Norms are presented in three age sets: 9 to 18, 19 to 39, and 40 to 88. In addition, norms for the Verbal Aggression and Physical Aggression scales are separated by gender. Written at a Grade three reading level, AQ items describe various characteristics related to aggression The respondent simply rates each item on a 5-point scale ranging from “Not at all like me” to “Completely like me”. Because it is brief and easy to read, the scale can be used with virtually anyone, including respondents who have difficulty with more complex verbal measures. The test can be hand-scored in minutes.
