Personality Correlates of Aggression: Evidence From Measures of the Five-Factor Model, UPPS Model of Impulsivity, and BIS/BAS

Although many studies of personality and aggression focus on multidimensional traits and higher order personality disorders (e.g., psychopathy), lower order, unidimensional traits may provide more precision in identifying specific aspects of personality that relate to aggression. The current study includes a comprehensive measurement of lower order personality traits in relation to three forms of aggression: reactive, proactive, and relational. Traits related to interpersonal antagonism and impulsivity, especially impulsive behavior in the context of negative affect, were consistently related to aggression across multiple indices. These findings suggest that certain lower order traits are of critical importance to understanding who engages in aggressive behavior and why this behavior occurs.     

Inquiry into Local Government Responsibilities and Funding

On 30 May 2002 I announced a major inquiry into local government. The inquiry is to be conducted by the multi–party House of Representatives Standing Committee on Economics, Finance and Public Administration. In this article I look at the background to the inquiry and at some of the things I hope it will achieve.     

Developmental explanations of delinquent behavior among siblings: Common factor vs. transmission mechanisms

We compare the statistical fit of two developmental explanations of delinquent behavior using longitudinal sibling data. The transmission effects model relates future delinquency to prior delinquency, delayed sibling effects, and unique environment. The common-factor effects model adds to these influences a latent variable representing persistent causes shared by siblings. These two models were fit to longitudinal data on 470 sibling pairs interviewed on three occasions. The common-factor effects model fit the data more closely than the transmission model. Nonmutually exclusive interpretations of the common effects model include (a) personality dispositions and (b) unchanging aspects of the social environment such as concurrent sibling effects and siblings' common friends.
