Evaluation of the Implementation of the Sex Offender Treatment Intervention and Progress Scale (SOTIPS), United States, 1978-2017 (ICPSR 37035)
The purpose of the project was to (1) determine whether the combined dynamic (SOTIPS) and static risk assessment (Static-99R) tools better predicted sexual recidivism than either alone, and (2) determine whether the tools could be implemented successfully in more representative populations. Previous research has established a "status quo" for risk assessments.
This study was set within the context of the developing sexual offender risk prediction field, where investigators explored reliable and valid means to assess what have been termed "dynamic risk factors." Instruments that identify the specific psychological risk factors present in the individual offender ought to allow treatment for that individual to be tailored to these specific needs, thus increasing its effectiveness. Thus, instruments have been designed to:
- Assess psychological factors that are empirically related to sexual recidivism, thus creating a basis for selecting treatment targets
- Show robust incremental predictive validity relative to Static-99R or other measures of static risk factors
- Measure change in a way that is convincingly related to sexual recidivism
- Incorporate and point risk managers towards some of the factors identified in the desistance literature
- Improve the effectiveness of treatment in reducing sexual recidivism
Enrollment of sex offenders in the evaluation study began in April 2013. To be included, offenders needed to be Static-99R eligible (an adult male convicted of a contact or non-contact sex offense with an identifiable victim), mentally cognizant, released to community supervision, and at least 18 years old in January 2013 in Maricopa County and April 2013 in New York City.
Multi-State Recidivism Study Using Static-99R and Static-2002 Risk Scores and Tier Guidelines From the Adam Walsh Act, Florida, Minnesota, New Jersey, South Carolina, 1990-2004 (ICPSR 34628)
This study seeks to examine important components of our nation's sex offender tracking and monitoring systems, with a focus on risk assessment and sexual recidivism (measured by re-arrest). Data were collected from 1,789 adult sex offenders in the following states.
- Florida: 500 cases
- Minnesota: 500 cases
- New Jersey: 291 cases
- South Carolina: 498 cases
The data file contains another 551 cases from the state of Massachusetts. However, due to how and when those cases were identified they were not included in the Principal Investigator's focus and analysis. There are also another 151 cases where a study participant's state is missing. Total there are 2,491 cases and 1,947 variables.
