Visual Reaction Time™ as a predictor of sexual offense recidivism.

In this study, we investigated the use of Visual Reaction Time™ (VRT™) for sexual interest in children to predict recidivism of sexual offenses among men who sexually abused children and men with other sexually deviant behaviors. The authors hypothesized that study participants with a higher VRT™ to stimuli of children would be more likely to sexually reoffend compared with those with a lower VRT™ to stimuli of children. Participants included 621 adult males on parole or probation for acting on a range of sexual paraphilias who sought outpatient treatment or evaluation at two separate therapists' practices.

Differences in the predictive validity of actuarial risk assessments in relation to sex offender type.

This study seeks to expand on the previously reported validity of the Static-99, RRASOR, MnSOST-R, and SORAG in predicting sexual recidivism utilizing a regional sample of offenders. The predictive validity of each test was determined utilizing subgroups of the sample based on each offender's known offense history. The effectiveness of each instrument varied depending on offender type.
