Predictive Validity of Lifestyle Impulsivity for Rapists

Abstract

This study examined the utility of lifestyle impulsivity as a typological discriminator for recidivism among rapists. Impulsivity was examined with respect to four criminal offense domains on a sample of 109 offenders discharged from a maximum-security treatment facility over a period of 25 years. In all instances, the hazard rate for the high-impulsivity group was at least twice as great as the hazard rate for the low-impulsivity group. For nonsexual, victimless charges, the hazard rate was almost four times as great.
