The aggressive behaviour of personality disordered patients and its relation to personality and perceptual motor performance

The present study investigates the relationship between the frequency of aggressive behaviour of patients in a therapeutic community and socialization, extraversion and perceptual-motor rule-breaking. The subjects were 33 males and 24 females who had been rated by two observers in regard to frequency of aggressive behaviour during the initial part of their stay in the community. Principal component analysis revealed two fairly pure factors, referred to as verbal and physical aggression. In females both factors correlated significantly with extraversion, lack of role-taking ability and perceptual-motor rule-breaking. No significant correlations were obtained in the male sample except that physical aggression correlated positively with perceptual-motor rule-breaking.
