The Buss–Perry Aggression Questionnaire (also known as the Aggression Questionnaire and sometimes referred to as the AGQ or AQ) was designed by Arnold H. Buss and Mark Perry, professors from the University of Texas at Austin in a 1992 article for the Journal of Personality and Social Psychology.
[1] The AQ was meant to be an improvement from a previous scale developed by Arnold H. Buss in 1957 with Ann Durkee which measured different types of interpersonal hostility, called the Buss-Durkee Hostility Inventory.
The scales and items of the Hostility inventory were developed following observations in clinical psychology situations, with limited statistical analysis.
[1] In 2000, the AQ underwent further development which expanded its factors into five, with indirect aggression as the addition.
[3] The final version of the AQ is meant for usage in normal populations starting from the age of 9 until 88 years old.
