美国性犯罪者登记制度的实证研究及反思

对性犯罪者进行登记是美国等西方国家普遍采用的用于遏制性犯罪的做法。但不少研究表明,性犯罪立法在控制性犯罪和减少再逮捕率方面并没有起明显作用,相反,性犯罪者登记制度给相当一部分性犯罪分子带来了诸多负面影响。关于性犯罪者登记制度需要进一步的研究,研究内容包括性犯罪者登记法是否能够减少性犯罪行为,谁来对登记程序进行监管,该制度对性犯罪者及其家庭的影响,以及实施登记法律的成本。     

Effectiveness of modified therapeutic community treatment within a medium-secure service for personality-disordered offenders

There is debate as to whether secure hospital treatment for offenders with personality disorder can be effective relative to criminal justice interventions. This study examines the evidence for long-term treatment of such offenders in hospital within in a modified therapeutic community model including accredited offending behaviour programmes. A panel sample of 47 patients were followed up on measures of violence risk (HCR-20, VRS) and symptom severity (SCL90-R). Intention-to-treat analysis with reliability thresholds showed significant positive change between assessment and discharge in both violence risk (VRS) and symptoms (SCL90-R) indicating a positive treatment effect. Threshold effects for treatment effectiveness seemed to occur at 1?year of treatment for risk and 3?years for symptom reduction.     

Characteristics of children with problem sexual behaviour and adolescent perpetrators of sexual abuse: a systematic review

ABSTRACT

People who commit sexual offences are a heterogeneous group, with research suggesting that children and young people commit a large proportion of all sex offences, especially those committed against other children. This systematic review provides a synthesis of literature concerning the characteristics of children and adolescents who exhibit harmful sexual behaviour. There is a particular focus in this review on studies that examine the characteristics of children and young people exhibiting these behaviours within institutional and organisational settings or which take a situational and/or developmental approach to understanding sexually abusive behaviour. Using a developmental and life-course criminology lens, this review explores implications from the literature for the prevention and response to child sexual abuse, with a particular focus on institutional contexts where the perpetrators are children and adolescents.     

Where Registered Sex Offenders Live: Community Characteristics and Proximity to Possible Victims

Recent developments in sanctions for sex offenders emphasize use of sex offender registries and residential restrictions in efforts to raise public awareness and keep offenders away from possible victims. One consequence of such efforts is to relegate registered sex offenders to socially disorganized communities. The present study draws on census tract level data from one urban county and assesses whether offenders are likely to be found in socially disorganized communities and in communities with high concentrations of potential victims. Findings show that registered sex offenders are more likely to reside in socially disorganized and disadvantaged communities, but not in locations with large pools of most types of possible victims (e.g., women living alone, children). Residential location is explained in terms of economic factors, not desire to live near possible victims. Implications for current policies and practices are discussed.     

Informing the Understudied R: Exploring and Advancing Typological Research

Creating offender typologies has become a growing interest and a potential method of improving understanding of programming needs and potential placements. Most typological research has only explored and described potential offender types. Relatively few studies have attempted to confirm the existence of created typologies or examine how offenders in each type predict important outcomes. Utilizing a large sample (N = 37,111) of reentering male offenders from Washington State Department of Corrections, we computed both an exploratory and confirmatory latent class analysis. After the confirmation of six offender types, we examined each type’s likelihood of several recidivistic outcomes. We anticipate that the described typology will assist case management, prioritizing offender needs, optimizing treatment services, and determining sequencing of multiple treatment types.     

The Effectiveness of Trace DNA Profiling—A Comparison Between a U.S. and a U.K. Law Enforcement Jurisdiction

Recovery, profiling, and speculative searching of trace DNA (not attributable to a body fluid/cell type) over a twelve‐month period in a U.S. Crime Laboratory and U.K. police force are compared. Results show greater numbers of U.S. firearm‐related items submitted for analysis compared with the U.K., where greatest numbers were submitted from burglary or vehicle offenses. U.S. multiple recovery techniques (double swabbing) occurred mainly during laboratory examination, whereas the majority of U.K. multiple recovery techniques occurred at the scene. No statistical difference was observed for useful profiles from single or multiple recovery. Database loading of interpretable profiles was most successful for U.K. items related to burglary or vehicle offenses. Database associations (matches) represented 7.0% of all U.S. items and 13.1% of all U.K. items. The U.K. strategy for burglary and vehicle examination demonstrated that careful selection of both items and sampling techniques is crucial to obtaining the observed results.     

“A different world” exploring and understanding the climate of a recently re-rolled sexual offender prison

Understanding how sexual offenders experience prison and its environment is important because such experiences can impact on rehabilitation outcomes. The purpose of this research investigation was to explore the rehabilitative and therapeutic climate of a recently re-rolled sexual offender prison. The research took a mixed methods approach and consisted of quantitative and qualitative phases. There were differences between prisoners and staff on their perception of the prison climate and for prisoner and staff relationships. The qualitative results helped to explain the quantitative findings and added a more nuanced understanding of the experience of the prison, the nature of prisoner and staff relationships and the opportunities for personal growth within the prison. The study has important implications for prisons that co-locate sexual offenders and want to provide an environment conducive to rehabilitation.     

The Sexual Violence Risk-20: factor structure and psychometric properties

Although the Sexual Violence Risk-20 (SVR-20) is widely used, its psychometric properties have only been investigated in a limited number of studies. This study explored the factor structure of the SVR-20 and examined its psychometric properties. Confirmatory factor analysis (CFA) was used to examine the fit of the original three-domain model of the SVR-20. The CFA showed that the original structure was not satisfactory. Exploratory principal components analysis (PCA) was conducted in search of a more optimal factor structure. Psychometric properties (i.e., internal consistency, predictive value, and convergent validity) of both the original domains and alternative factors were investigated. The PCA and subsequent CFAs pointed in the direction of an alternative, more optimal three-factor solution. The three alternative factors were labeled as Antisociality, Sexual deviance, and Problematic thinking and produced better internal consistency coefficients than the original domains. However, the validity of the SVR-20 was modest and no evidence was found indicating that the alternative factors were better in this regard as compared to the original domains. Despite the overall superiority of actuarial measures in predicting recidivism, the structured professional judgment of the SVR-20 proved to be more predictive of sexual, violent, and general recidivism than its actuarial scoring method.
