An Analysis of the Effectiveness of Community Notification and Registration: Do the Best Intentions Predict the Best Practices?

Abstract

This research measures group differences in recidivism before and after implementation of Megan’s Law. The pre–post study consists of a total of 550 male sex offenders released during the years 1990 and 2000, of which 250 offenders were released during 1990 and 1994 (i.e., the pre‐Megan’s Law group) and 300 offenders were released between 1995 and 2000 (i.e., the post‐Megan’s Law group). Offenders were released from a general population setting and a sex offender specific treatment facility. The main variables of concern include: (1) recidivism levels, (2) days to first re‐arrest, and (3) level of harm (i.e., number of sex offenses, violent offenses, and number of child victims). Statistical findings from chi‐square and survival analysis testing indicate significant group differences on levels of general recidivism; however, no significant differences were identified on measures of sex offense recidivism. Implications of these findings on sex offender specific policies are discussed.
