Criminologists are ofren interested in examining interactive effects within a regression context. For example, “holding other relevant factors constant, is the effect of delinquent peers on one’s own delinquent conduct the same for males and females?” or “is the effect of a given treatment program comparable between first-time and repeat offenders?” A(More)
Age is one of the most robust correlates of criminal behavior. Yet, explanations for this relationship are varied and conflicting. Developmental theories point to a multitude of sociological, psychological, and biological changes that occur during adolescence and adulthood. One prominent criminological perspective outlined by Gottfredson and Hirschi claims(More)
Exposure to alcohol and illicit drugs during early adolescence has been associated with poor outcomes in adulthood. However, many adolescents with exposure to these substances also have a history of conduct problems, which raises the question of whether early exposure to alcohol and drugs leads to poor outcomes only for those adolescents who are already at(More)
Improving juvenile court decision making requires information about how serious adolescent offenders desist from antisocial activity. A systematic research agenda on this topic requires consideration of several processes, including normative development in late adolescence, what constitutes desistance, and the factors likely to promote the end of(More)
Prior studies have documented linkages between mental disorder and both offending and victimization. However, few studies have examined the violent offending-violent victimization overlap among mentally disordered individuals and none have examined the factors that are jointly related to their covariation. Here, we assess this overlap during the first ten(More)
For many years, notes Alex Piquero, youth of color have been overrepresented at every stage of the U.S. juvenile justice system. As with racial disparities in a wide variety of social indicators, the causes of these disparities are not immediately apparent. Some analysts attribute the disparities to "differential involvement"--that is, to differences in(More)
Multiple theories suggest mechanisms by which the use of alcohol and drugs during adolescence could dampen growth in psychosocial maturity. However, scant empirical evidence exists to support this proposition. The current study tested whether alcohol and marijuana use predicted suppressed growth in psychosocial maturity among a sample of male serious(More)
Gottfredson and Hirschi claim that self-control is the only enduring personal characteristic implicated in criminal activity. Other scholars, such as Moffitt and Rowe, claim that although self-control is important, so are neuropsychological and physiological factors. This study attempts to adjudicate between these two positions by examining the ways in(More)
INTRODUCTION Gottfredson and Hirschi's theory that there is an underlying factor accounting for all sorts of antisocial behaviour has attracted widespread theoretical and empirical attention. One of their most controversial statements is a 'generality' hypothesis, a notion that criminal, deviant and reckless acts are highly correlated because they are(More)
Because many serious adolescent offenders reduce their antisocial behavior after court involvement, understanding the patterns and mechanisms of the process of desistance from criminal activity is essential for developing effective interventions and legal policy. This study examined patterns of self-reported antisocial behavior over a 3-year period after(More)
