An extensive analysis of the recidivism of male sex offenders (n = 9,691) over a 3 year period, who released in 1994 by the prison systems of 15 States. In addressing sex offender recidivism, this study addressed demographic characteristics, sentence length and time, criminal history, established risk assessment variables, and characteristics of the rearrest, as well as the characteristic of the victims.

Minnesota Department of Corrections analysis of sexual reoffense patterns of 224 recidivist initially released from prison between 1990 and 2002 and the current residency restrictions of that state. Results of this analysis suggest that residential proximity had very little impact on the 224 offenses for two identified reasons. First, social or relationship proximity was found to be of greater significance and, second, where direct contact was made, offenders were unlikely to do so close to their residences.

Minnesota Department of Corrections evaluation of sex offenders (n = 3,166) released from a Minnesota Correctional Facility between 1990 and 2002. Focus was placed on the impact of post-release supervision in recidivism reduction. However, established variables for risk assessment were evaluated as well as other variables associated with sex offender recidivism such as methods of sexual reoffending, offender characteristics, and treatment intervention.

Under Washington's SVP Law, Where No Petition Was Filed, Milloy, December 2003, WSIPP - Washington State Institute for Public Policy evaluation of sex offenders (n = 89) released to the community between July 1990 and July 1996 who were referred by the Washington Department of Corrections as meeting the filing standards for civil commitment petitions pursuant to Washington's Sexually Violent Predator stature under the 1990 Community Protection Act. The evaluation concluded that individuals in this group have a high risk of subsequent conviction for a felony offense, particularly a new against-person offense, a category that includes sex offenses.

This report updates results from previous reports about the effects of sanctions for juveniles, females, and minority groups. Findings are: 1. Type of sanction is unrelated to decreases in recidivism under any of the three conditions. 2. There are no differential effects of type of sanction on any of the 3 groups examined. 3. There are tentative indications that increasing lengths of incarceration are associated with slightly greater increases in recidivism. Conclusions are: 1. Prisons and intermediate sanctions should not be used with the expectation of reducing criminal behavior. 2. Excessive use of incarceration may have substantial cost implications. 3. In order to determine who is being adversely affected by time in prison, it is incumbent upon prison officials to implement repeated, comprehensive assessments of offenders’ attitudes, values, and behaviors throughout the period of incarceration and correlate these changes with recidivism upon release into the community.

Dr. Berlin reviews and comments on the Weinberger et al. article " The impact of Surgical Castration on Sexual Recidivism Risk. . . " He asserts that Weinberger et al. "appear to be most concerned that the castration data reviewed not be too heavily weighted in support of a possible release into the community, this commentary is meant to balance that argument by cautioning against underestimating its possible importance."

This 2005 article published in The Journal of the American Academy of Psychiatry and the Law reviews the relationship of surgical castration to sexual recidivism in a sexually violent predator/sexually dangerous person (SVP/SDP) population. A review of the literature on castrated sex offenders reveals a very low incidence of sexual recidivism. The low sexual recidivism rates reported are critiqued in light of the methodologic limitations of the studies.
