In search of the origins of crime continuity: Aggressive versus nonaggressive delinquency as a key factor in the psychological inertia process

The purpose of this study was to test whether the psychological inertia process believed to give rise to crime continuity is limited to aggressive delinquency or evolves from both aggressive and nonaggressive delinquency. Self-report data provided by 845 early adolescent youth (406 boys, 439 girls) were analyzed in an effort to test the hypothesis that aggressive rather than nonaggressive delinquency precipitates a rise in delinquency through the intervening influence of cognitive impulsivity but not moral neutralization. The hypothesis stated that of the four models evaluated in this study (aggressive delinquency → moral neutralization → offense variety; aggressive delinquency → cognitive impulsivity → offense variety; nonaggressive delinquency → moral neutralization → offense variety; nonaggressive delinquency → cognitive impulsivity → offense variety), only the aggressive delinquency → cognitive impulsivity → offense variety model would achieve significance. Consistent with this hypothesis, only the aggressive delinquency → cognitive impulsivity → offense variety pathway was, in fact, significant. The current findings suggest that the psychological inertia process may be driven by a pattern of aggressive delinquency followed by cognitive impulsivity and that neither nonaggressive delinquency nor moral neutralization contribute to the process. Theoretical and practical implications of these results are discussed.
