The Static-99R Is Not Valid For Women: Predictive Validity in 739 Females Who Have Sexually Offended.

Abstract

Although many instruments have been validated to assess risk of sexual recidivism among men, no similar tool exists for women who have sexually offended. As a result, some jurisdictions use male-based instruments to assess women despite the lack of validation research examining the predictive utility for this subgroup. This study examined the utility of the Static-99R in predicting sexual recidivism among women. Based on a sample of 739 women convicted of sexual offenses in Texas, findings show that the total score was not significantly associated with sexual recidivism. When looking at individual items, other than a history of prior sexual offenses and noncontact sexual offenses, no item of the Static-99R was significantly associated with sexual recidivism among women. Furthermore, only three items (female victims/solo offender, 4+ sentencing dates, and having not lived with a romantic other for 2+ years) were significantly associated with nonsexual recidivism. These findings indicate that the Static-99R is not suitable to assess risk of recidivism among women convicted of sexual offenses.
