The researchers examined the relationships between dating violence and anger, psychoticism, and addiction. The participants were 440 Korean college students (173 males and 267 females) whose ages ranged from 17 to 33 (M=20.89, SD=2.27). The questionnaires and psychological tests used in this research included the following: Straus' Conflict Tactics Scale, Spielberger's State-Trait Anger Expression Inventory, and Eysenck's Personality Inventory. Research design was a 2 (sex) × 4 (types of dating violence experience) 2-way MANOVA. Results indicated that people who had inflicted and received violence in their dating relationship had significantly higher trait anger, anger-in, and anger-out than people who had not experienced dating violence, while people who received dating violence showed higher anger control than people who had inflicted dating violence or who had inflicted and received dating violence. There was a 2-way interaction in psychoticism by sex and types of dating violence experience. Males who had inflicted and received dating violence had significantly higher psychoticism than males who had not experienced dating violence. And it was found that people who had inflicted and received dating violence were likely to show higher addiction than people who had not experienced dating violence.
