Risk assessment of child-victim sex offenders for extended supervision in New Zealand

Recently enacted legislation in New Zealand, the Parole (Extended Supervision) Amendment Act 2004, allows for the imposition of up to 10 years of supervision in the community for child-victim sex offenders following their release from prison. The Act requires reports to be written specifically assessing the risk of sexual re-offending against children. This study examined the application of actuarial measures used by the New Zealand Department of Corrections in these assessments, including a computer-scored instrument based on static factors (the Automated Sexual Recidivism Scale; ASRS) and a clinically-based judgement of dynamic risk factors (the SONAR). It was expected that a conservative approach would be taken in making recommendations for or against extended periods of supervision, such that a high score on either measure would predict a recommendation for extended supervision. It was found, however, that a more individualized approach was often taken, whereby a baseline assessment of risk as predicted by the ASRS was adjusted by clinicians based on SONAR ratings. Implications for the practice of risk assessment in sexual re-offending are discussed.

Short term reoffending by child victim sex offenders in New Zealand : a comparison of those with and without extended supervision

Sexual offenders with child victims in New Zealand who are considered at high risk for reoffending are subject to an Extended Supervision Order. This allows for a period of supervision of up to ten years following release to the community. The present study examined 89 offenders given Extended Supervision Orders over the 33 month period since the legislation was enacted. All types of reoffending resulting in criminal convictions by this group were included. A matched sample of sexual offenders with child victims released prior to this legislation and a sample of offenders judged to be lower risk were compared to those under extended supervision. Offenders under extended supervision reoffended faster and at a higher rate for both sexual and general offences than those deemed lower risk, but at a lower rate than pre-extended supervision high risk offenders. The relationship between specialist treatment programme attendance and completion, actuarial risk level, and recidivism in the extended supervision sample were also investigated. These variables were found not to be significant predictors of sexual recidivism.

Programs for men who perpetrate domestic violence : an examination of the issues underlying the effectiveness of intervention programs

This review paper seeks to explore some of the reasons why rehabilitation programs for male perpetrators of domestic violence appear to be less effective in reducing recidivism than programs for other offender groups. It is argued that while the model of systems response to domestic violence has predominated at the inter-agency level, further consideration might be given to way in which men’s intervention groups are both designed and delivered. It is concluded that the program logic of men’s domestic violence programs is rarely articulated leading to low levels of program integrity, and that one way to further improve program effectiveness is to incorporate some of the approaches evident in more general violence prevention programs and from what is know about good practice in general about offender rehabilitation.

The process of change in offender rehabilitation programmes

Whilst the overall effectiveness of offender rehabilitation programmes in reducing recidivism is now well established, there has been less discussion of the reasons why rehabilitation programmes may be unsuccessful for some offenders. In this paper we suggest that models of change developed in counselling and psychotherapy may have utility in explaining how offender rehabilitation programmes bring about change, and argue that the dominance of cognitive-behavioural treatments in the rehabilitation field means that those offenders who have particularly low levels of problem awareness may be at increased risk of treatment failure. Understanding more about the mechanisms by which programmes help offenders to desist from offending is likely to lead to the development of more responsive and, ultimately, more effective programmes. Some suggestions for those involved in the delivery of offender rehabilitation programmes include: being mindful of the sequence of components of programmes, the development of preparation (or readiness) programmes and offering a broad suite of programmes to cater for different stages of problem awareness and assimilation among offenders.

Specific risk assessment based on victim type in children sexual offenders

Actuarial instruments for assessing sex offender recidivism have limited utility for specific risk assessment questions, such as the risk posed to particular types of victim. In order to obtain variables that discriminate between offenders with different classes of victim, data were coded from 324 files of child sexual offenders from a community-based sexual offender treatment program. Offenders with single or multiple victims were compared, as were offenders who did or did not offend against victims of both genders, and offenders with only intra-familial or extra-familial victims versus offenders with victims in both relationship categories. Variables that discriminated single-victim and multiple-victim offenders were similar to those identified in actuarial risk assessment scales, with the exception of history of childhood sexual abuse. With the exception of physical abuse history, the same variables discriminated specific offender groups according to victim gender and victim relationship, although in different combinations. There was limited support for the notion of specific risk variables.

Problem assimilation and offender rehabilitation

Whilst the overall effectiveness of offender rehabilitation programs in reducing recidivism is now well established, there has been less discussion of the reasons why rehabilitation programs may be unsuccessful for some offenders. In this paper we suggest that the Assimilation model of change (Stiles et al., 1991) may have utility in explaining how offender rehabilitation programs bring about change, and argue that those offenders who have particularly low levels of problem awareness may be at increased risk of treatment failure. Methods of measuring problem awareness and treatment readiness are discussed along with possible methods of intervention, including the Pennebaker method.

Alcohol use and negative affect in the offence cycle

Introduction : It is commonly acknowledged that, for many offenders, alcohol use is strongly associated with criminal behaviour. The belief held by many professionals that the two phenomena are associated, probably in a causal way, has led to the inclusion of alcohol use as a ‘criminogenic need’ in many settings where rehabilitation programmes are used to reduce recidivism. However, the mechanisms and pathways involved in the alcohol–crime link remain poorly understood.

Argument and conclusion : This paper reviews the literature relating to alcohol–offending links and draws some inferences about the role of alcohol use as a criminogenic need in offender rehabilitation. It is proposed that the bi-directional relationship between alcohol use and negative affective states is important in understanding the offence cycle, and that deficits in self-regulation not only characterize both alcohol misuse and negative affect but are also implicated in the offending behaviour itself.

The multifactor offender readiness model

There has been a resurgence of interest in the rehabilitation of offenders. Research has consistently shown that rehabilitation programs for offenders, when they adhere to general principles of program design and delivery, will achieve significant reductions in recidivism. In this paper, we suggest that even greater reductions in recidivism can be achieved when readiness is addressed at the level of the individual offender, the program, and the context. A comprehensive understanding of readiness allows for fuller engagement in treatment, thus increasing probability of good treatment outcomes. We describe person, program, and context factors in a model of offender treatment readiness and discuss implications of the model for both assessment of offenders and for modification of low readiness.

Pathways to sex offending

The research of the thesis aimed to contribute to the theoretical understanding of the various pathways that offenders follow in committing sexual offences. Using grounded theory a theoretical model was generated which described four major pathways to sexual offending. Quantitative analyses revealed that offenders who take different pathways differ significantly in respect of their risk of recidivism, demographic variables, rape myth acceptance and aggression. The portfolio considered the limitations of sex offender treatment programs for treating sex offenders with histories of childhood sexual abuse and presented four case studies.

Violent offending : the efficacy of a unitary and transtheoretical intervention

Examines "best practice" in reducing recidivism. Compares two interventions for violent offenders, and examines whether their different theoretical orientations (unitary or transtheoretical) affected program efficiency. Although the transtheoretical intervention was more efficacious, insufficient adherence to best practice principles within implementation of both programs significantly impinged upon program success.

Police officers' questioning of children about repeated abuse

This thesis examined the perceptions of police and legal professionals regarding how police officers should and do interview children about repeated abuse. It also examined the actual performance of police interviewers in mock and field interviews to understand the reason for interviewer's difficulties and how interview strategy can be improved. The portfolio examines and discusses the complexities associated with assessing the risk of sexual recidivism among different sex offender populations - adult sex offenders, sex offenders with an intellectual disability, adolescent sex offenders and indigenous sex offenders. Four case studies are presented.

Individual differences in affective responses to violence and sexual violence

The thesis aimed to identify and compare individual differences in anger related affective responses upon exposure to neutral, violent and sexually violent film. The findings revealed that both graphic and non-graphic sexually violent film content may have a stronger impact on viewers' anger levels than exposure to standard violent film. The portfolio examined in four case studies the utility of the Violence Risk Scale when seeking to identify factors associated with risk of violent recidivism and subsequent treatment targets for intellectually disabled offenders . Treatment indications must consider the impaired cognitive and adaptive abilities and the difficulties inherent in modifying the behavioural characteristics of intellectually disabled offenders.

Risk assessment with female sex offenders : can women meet the criteria of community protection laws?

Although females represent a small proportion of the sex offender population, they occasionally appear before the courts under the current generation of laws intended to protect the public from high-risk sex offenders. In this context, practitioners are called upon to provide assessment of the risk these women pose for sexual re-offending. The primary issues addressed in this paper are related to the validity of conducting such risk assessments and providing professional opinions as to the risk of further sexual offences that may be committed by female offenders. The approach taken is to summarize briefly the available professional literature regarding female sex offenders, and then to present the findings of the relatively few empirical studies that address sexual recidivism in females. The final section examines the positions taken in the published works of various international experts regarding risk assessment with females, followed by conclusions and recommendations in light of the standards typically prescribed by community protection laws.

Recent research (N=9,305) underscores the importance of using age-stratified actuarial tables in sex offender risk assessments

A useful understanding of the relationship between age, actuarial scores, and sexual recidivism can be obtained by comparing the entries in equivalent cells from “agestratified” actuarial tables. This article reports the compilation of the first multisample age-stratified table of sexual recidivism rates, referred to as the “multisample age-stratified table of sexual recidivism rates (MATS-1),” from recent research on Static-99 and another actuarial known as the Automated Sexual Recidivism Scale. The MATS-1 validates the “age invariance effect” that the risk of sexual recidivism declines with advancing age and shows that age-restricted tables underestimate risk for younger offenders and overestimate risk for older offenders. Based on data from more than 9,000 sex offenders, our conclusion is that evaluators should report recidivism estimates from age-stratified tables when they are assessing sexual recidivism risk, particularly when evaluating the aging sex offender.

Applying the good lives model to male perpetrators of domestic violence

Domestic violence is a pervasive social problem that has devastating emotional, physical, psychological, and financial costs for individuals, families, and communities. Despite the widespread use of current intervention programmes, recent reviews have demonstrated that these have only a small impact on the reduction of recidivism. In this article, we briefly summarise the features identified in the literature that distinguish domestically violent men from those who do not engage in such behaviours. We then explore the most common interventions used to treat domestic violence offenders and discuss the limitations of these interventions, before outlining the assumptions of the Good Lives Model (GLM), a strengthbased approach to the treatment of offenders. We discuss the advantages of using the GLM compared to existing approaches and finally, we consider future directions for the use of the GLM in domestic violence interventions.
