Summary
This study validated the Aggression Questionnaire, finding general support for its four-factor structure. Removing two suspicion items may improve the hostility factor
Area of Science:
- Psychology
- Social Psychology
- Personality Psychology
Background:
- The Aggression Questionnaire (AQ) by Buss and Perry (1992) is widely used.
- Assessing the AQ's factor structure is crucial for its valid application.
- Previous research suggests a four-factor model for aggression.
Purpose of the Study:
- To conduct a confirmatory factor analysis (CFA) of the AQ.
- To evaluate the empirical support for the proposed four-factor structure of the AQ.
- To identify potential improvements to the AQ's factor structure.
Main Methods:
- Confirmatory factor analysis (CFA) was employed.
- The AQ's factor structure was statistically examined.
- Item loadings and internal reliability were assessed.
Main Results:
- The general four-factor model of the AQ received support.
- Two specific items related to suspicion showed low loadings on the hostility factor.
- Removing these two items is suggested to enhance the hostility factor's reliability.
Conclusions:
- The AQ largely maintains its intended four-factor structure.
- The hostility subscale may benefit from item refinement.
- Further validation of the modified AQ is warranted.
