title: Examination of South Carolina's Sex Offender Registration and Notification (SORN) Policy in Reducing Sexual Violence, 1990-2005
title: Archival Version

description: This study examined the effects of comprehensive registration and community notification policies on rates of sexual violence in South Carolina. Specifically, it proposed to (1) evaluate whether broad sex offender registration and notification policies have reduced recidivism or deterred new sexual offenses, (2) examine whether unintended effects of broad registration and notification policies occurred, and (3) focus on the effects of registration and notification as it pertained to offenses committed by adults. The study examined whether the introduction of sex offender registration and notification laws in South Carolina were associated with reductions in sexual crimes and, if so, whether this reduction could be attributed to an actual reduction in sexual violence and/or recidivism (i.e., an intended effect) or to changes in criminal judicial processing of individuals for registry crimes (i.e., an unintended effect). Specific study aims included examining whether: (1) South Carolina registration and notification policies had the intended effect of preventing first time sexual offending; (2) South Carolina registration and notification policies had the intended effect of reducing sexual recidivism for known sex offenders; and (3) South Carolina registration and notification policies had the unintended effect of reducing the probability that individuals who committed sexual crimes would be prosecuted or convicted for such crimes. In addition to these primary aims, the researchers also investigated (4) registration violations (e.g., failure to register) were associated with sexual or general recidivism.
description: The program of research sought to extend research on the effects of registration and notification to an offense-based sex offender registration and notification (SORN) policy enacted by South Carolina. South Carolina was selected to model the effects of registration and notification on sex crime deterrence, sexual recidivism risk, and to examine unintended effects on judicial decision making for two reasons. First, South Carolina was one of the first states to respond to federal registration requirements, enacting an original registration policy in 1995 and expanding notification to require online notification in 1999. Thus, longer follow-up was achievable using South Carolina criminal justice databases than in states with more recent policies. Second, South Carolina's registration policies were of interest because they exceeded, in nearly every respect, the original federal registration and community notification requirements established by the Jacob Wetterling, Megan Kanka, and Pam Lychner Acts in the 1990's and continue to exceed many of the expanded requirements more recently established by the Adam Walsh Act. The specific aims of the program of research was: Prevention (General Deterrence) of Sexual Violence. This included an examination of whether South Carolina's SORN policy was associated with a general deterrent effect for adults. Specifically, it addressed the question of whether registration and notification deterred first time sex crimes. ; Specific Deterrence of Sexual Recidivism. This included an examination of whether South Carolina's SORN policy associated with specific deterrent effect on sexual and nonsexual violent recidivism rates for adults. Specifically, it addressed the question of whether registration and notification reduced sexual and nonsexual recidivism rates. ; Unintended Effects on Judicial Decision Making for Sex Crime Cases. This included an examination of whether South Carolina's SORN policy was associated with unintended effects on judicial decision making specific to adult sex crime cases. Specifically, it addressed the question of whether registration and notification influenced the likelihood that a sex crime charge would result in a formal judicial processing (versus being dismissed) and whether a sex crime charge would result in a guilty finding (vs. acquittal). ; Association Between Registration Violations and Sexual Recidivism. This included an examination of whether failure to register is associated with increased risk for sexual recidivism. ;
description: Sex Offender Registry Records South Carolina sex offender registry data were obtained from the South Carolina Law Enforcement Division (SLED) in collaboration with the South Carolina Office of Justice Programs Statistical Analysis Center. The SLED data files included all offenders registered from the date of initial registration policy implementation (January 1st, 1995) through December 31st, 2005. Adult Criminal History Records Computerized criminal history records between January 1, 1990 and December 31, 2004 were obtained from SLED, in collaboration with South Carolina State Budget and Control Board, Office of Research and Statistics (ORS) for analysis. Juvenile Justice Records Juvenile justice data were obtained from the South Carolina Department of Juvenile Justice in collaboration with ORS. These data were used primarily to provide information about prior arrest histories. South Carolina Population Records South Carolina population estimates were obtained from South Carolina Community Assessment Network (SCAN) population data tables, available at the South Carolina Department of Health and Environmental Control website.

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Performed consistency checks.; Created variable labels and/or value labels.; Standardized missing values.; Checked for undocumented or out-of-range codes..
