Abstract
The purpose of this study is to demonstrate the relationship between the five-factor model of personality and its association with aggression in 30 men and eight women who are suspects of domestic violence. The results show a positive correlation between neuroticism and hostility, a negative correlation between openness to experience and overall aggression, a negative correlation between agreeableness and physical aggression and anger, and a negative correlation between conscientiousness and anger. These results show us the need for personality assessment in domestic violence suspects and future research about personality and aggression.
