The aim of this study was to vefify whether static factors (criminal history, age, relationship status) and dynamic factors (deviance index based on phallometric data, score of psychometric testing) permit prediction of recidivism in sexual aggressors. Three types of recidivism (sexual, violent, criminal) were determined in 113 rapists and in 269 child molesters over an average follow-up of 64.5 months. The sexual reconviction rate was 21.2% in rapists and 13% in child molesters. Reconvicted rapists were younger and had more previous convictions than those who were not reconvicted, Compared with those who did not reoffend, the child molesters who were reconvicted for a sexual offense had higher pedophilic indices, had more previous sexual charges, were younger, more frequently had male victims, had more frequently extrafamilial victims, and a higher percentage of them were living alone. Psychometric data did not predict recidivism in either rapists or child molesters.

The aim of the current study was to assess the role of a treatment program (uncompleted; completed ; extended) on the posttreat-ment recidivism of sexual aggressors. Data on five types of recidivism (sexual ; violent ; property offense ; against a person ; total) were gathered for 102 pedophiles and 70 rapists. The recidivism rates for pedophiles who completed the treatment program was lower than for those of the pedophiles who did not complete the treatment. As to the rapists, the recidivism rates were lower for those who underwent an extended treatment program than for the other two groups. These data show that a treatment program reduces the recidivism rate in sexual aggressors. The optimal duration of treatment, however, varies according to the type of offender
