Assessing reconviction,reoffending and recidivism in a sample of UK sexual offenders

Purpose. The rate of sexual reconviction for sexual offenders is known to be low. Sexual reconviction, however, is currently the most commonly used outcome measure in sex offender treatment evaluation studies. It is expected that sex offender treatment programmes will reduce the likelihood of reconviction amongst participants. A low base rate of sexual reconviction means that any reduction in reconviction (which could be attributed to treatment) will be small and unlikely to be statistically significant. This study aimed to assess other offence‐related outcomes for sexual offenders, in addition to reconviction. Methods. The sample comprised 173 sexual offenders who had completed a community sex offender treatment programme. Follow‐up information was collected forthe sample from programme files containing multi‐agency information. Official reconviction rates were also calculated using both Home Office and police data. Results. Collecting evidence of any offence‐related sexual behaviour during this study multiplied the sample's sexual reconviction rate by a factor of 5.3. Conclusions. The results show that broadening the outcome measure under observation indicates a higher level of offence‐related sexual behaviour displayed by sexual offenders than reflected by reconviction data. These results have implications for the outcomes measured in treatment evaluation research for sexual offenders.     

Effective interventions for acquisitive offenders: An investigation of cognitive skills programmes

Purpose. Previous research has suggested that cognitive skills programmes completed by offenders may be more effective in reducing reconviction with nonacquisitive than acquisitive offenders. This study investigates whether a similar pattern is present with offenders who have completed accredited cognitive skills programmes in prisons in England and Wales. Method. Questionnaires measuring the cognitive deficits targeted by the programmes were administered to 8,303 offenders participating in cognitive skills programmes while in custody. A checklist on the individuals' behaviour was also completed for each participant. The questionnaires and the behaviour checklist were completed before, after, and at 8 weeks after the end of the course. Participants were assigned to one of three groups dependent upon the number of convictions they had received for acquisitive offences; non‐acquisitive, medium acquisitive and high acquisitive. Results. Offenders in the high acquisitive group showed greater need in the cognitive deficits at the pre‐course stage than the other two groups, for both the self‐completion questionnaires and the behaviour checklist. A comparison of preand post‐course scores on the questionnaires and the behaviour checklist showed positive effect sizes for all three groups. Some of the variables showed a greater change from pre‐ to post‐course in the groups that had been convicted of more acquisitive offences. Conclusion. Cognitive skills programmes appear to be as effective with offenders convicted of acquisitive crime as non‐acquisitive crime, although highly acquisitive offenders may benefit from an additional intervention. Further studies are needed to investigate whether this same result is upheld when the outcome measure is reconviction.     

Evaluation of a national prison-based treatment program for sexual offenders in England and Wales

Treatment efficacy is described for a sample of sexual offenders who had undertaken treatment in United Kingdom prisons (N = 647) and for a retrospectively selected comparison group (N = 1,910). The outcomes under observation in this study were sexual, sexual and/or violent, and general reconviction. Treatment impact was also examined in relation to offenders' risk of reconviction. The treatment group had slightly lower 2-year sexual reconviction rates than the comparison group, but these differences were not statistically significant. Significant differences were found between the treatment and comparison group for sexual and/or violent reconviction. Further analysis suggested that treatment produced a reduction in the probability of sexual and/or violent reconviction (p <.05) when other relevant variables were controlled for. General reconviction rates were consistently lower in the treatment group, but these differences were not significant.     

Cross-validation of the risk matrix 2000 sexual and violent scales

The predictive accuracy of the newly developed actuarial risk measures Risk Matrix 2000 Sexual/Violence (RMS, RMV) were cross validated and compared with two risk assessment measures (SVR-20 and Static-99) in a sample of sexual (n= 85) and nonsex violent (n= 46) offenders. The sexual offense reconviction rate for the sex offender group was 18% at 10 years follow-up, compared with 2% for the violent offenders. Survival analyses revealed the violent offenders were reconvicted at twice the rate compared to sexual offenders. The RMV significantly predicted violent recidivism in the sex and combined sex/violent offender groups. Although the RMS obtained marginal accuracy in predicting sexual reconviction in the sex offender group, none of the scales significantly predicted sexual reconviction. An item analysis revealed four factors not included in the risk scales that were significantly correlated with sexual and violent reconviction. Combining these factors with Static-99, RMV, and RMS increased the accuracy in predicting sexual reconviction.     

Motivational interviewing with offenders: A systematic review

Purpose. Offender motivation is one specific responsivity variable in offender treatment and motivational interviewing (MI) is commonly used by corrections personnel. Although evidence for the effectiveness of motivational interviewing is accruing overall, a review of MI specifically with offender populations is required. Method. Relevant databases and websites were searched using terms relating to MI with offenders. Results. In total, 13 published studies and 6 dissertation abstracts were identified. MI is most evaluated in relation to substance misusing offenders (N=10). Other applications are with domestic violence offenders (N=3), drink‐drivers (N=5), and general offending (N=1). In these populations, MI is used to enhance retention and engagement in treatment, improve motivation for change, and change behaviour. Conclusions. MI can lead to improved retention in treatment, enhanced motivation to change, and reduced offending, although there are variations across studies. To advance the study of MI with offenders, a theory of change needs to be articulated on which testable hypotheses may be based. The integrity of treatment in its application needs to be assured. Based on these foundations, more outcome research is needed to examine who responds to what type of MI in relation to treatment retention, readiness to change, and reconviction.     

Offending behaviour programmes in the community: The effects on reconviction of three programmes with adult male offenders

Purpose . This study presents the findings of an evaluation of the effect on reconviction of three general offending behaviour programmes in the English and Welsh Probation Service with adult male offenders. Method . The study employed a quasi‐experimental design comparing the reconviction rates of three groups: offenders who were allocated to and completed a programme, offenders allocated to a programme but failed to complete, and a comparison group. Results . The main finding from the analyses indicated that, controlling for salient population factors, the offenders who had completed a programme had a lower rate of reconviction as compared with non‐completers and comparison groups. Additionally, the non‐completers had a higher rate of reconviction than the comparison group. Conclusions . The findings are discussed in light of the extant literature and a range of explanations is presented.     

Using clinical variables to evaluate treatment effectiveness in programmes for sexual offenders

Abstract

Typically, sex offender programmes are evaluated using recidivism, a distal outcome measure. This paper proposes that sex offender programmes also incorporate proximal variables to evaluate treatment effectiveness. Proximal variables assess within treatment changes immediately following the intervention. To demonstrate this approach, the effectiveness of a sex offender treatment programme is evaluated using proximal variables, specifically locus of control, empathy, cognitive distortions and acceptance of responsibility. We provide the findings of this evaluation and discuss the implications of this approach. In particular, we conclude with the importance of identifying relevant treatment targets and selecting suitable proximal measures of those targets in evaluating treatment effectiveness.     

Measuring the real impact of accredited offending behaviour programmes

Purpose. This paper describes an integrated model for the evaluation of offending behaviour programmes in order to assess their real impact. Arguments. To date there has been an over‐reliance on reconviction data as the sole measure of treatment efficacy. Reconviction has a fundamental role to play but cannot be considered in isolation from other empirically related treatment and re‐settlement factors. A rigorous reconviction study requires an adequate comparison group but few papers describe with transparency how this has been achieved. There is also the assumption that participation in treatment renders an individual offender as treated. A treated profile is contingent upon the treatment climate, the quality of programme delivery and how the individual responds to treatment. The influence of life‐style or dynamic risk factors must also be acknowledged in terms of their effect on reconviction. Conclusions. It is recommended that researchers use an integrated approach to the evaluation of accredited offending behaviour programmes. In order to establish a broad balance of treatment outcomes, a shift away from reconviction rates is needed. This paper presents an integrated model for the evaluation of offending behaviour programmes.     

The impact of sex offender’s interpersonal style,treatment readiness and the therapeutic alliance on treatment gain

The impact of internal responsivity factors and therapeutic process variables on intra-individual within-treatment gain in sex offenders has received little empirical attention. This study examined how (1) internal responsivity factors, including treatment readiness and interpersonal style, and (2) therapy process variables, including the therapeutic alliance and the presence of ruptures in the therapeutic relationship, impacted intra-individual within-treatment gain. Participants comprised 71 sex offenders who participated in group-based sex offender treatment programmes in prison or the community. Results showed that offender hostile-dominance and the affective and interpersonal characteristics of psychopathy, as measured by the Psychopathy Checklist: Screening Version Factor 1 score, negatively impacted treatment gain. Pre-treatment readiness, client ratings of the therapeutic alliance and whether or not there were ruptures in the therapeutic relationship had no association with within-treatment gain. The strength of the therapeutic alliance later in treatment did not moderate the relationship between offender interpersonal style, or psychopathy, and treatment gain.     

The process of change in offender rehabilitation programmes

Abstract

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.     

THE IMPACT OF MEGAN'S LAW ON SEX OFFENDER RECIDIVISM: THE MINNESOTA EXPERIENCE*

Although Megan's Law was passed more than 10 years ago, very little is known as to whether it reduces sex offender recidivism significantly. Using a retrospective quasi‐experimental design, we examine whether community notification has a deterrent effect by comparing the recidivism rates of 155 level 3 (“high public risk”) sex offenders released from Minnesota prisons between 1997 and 2002 who were subject to broad notification with two separate control groups who were not. The first control group (referred to as the prenotification group) contained 125 sex offenders released between 1990 and 1996 (the 7 years preceding the implementation of the Community Notification Act) who likely would have been subject to broad community notification had the law been in effect at the time of their release. The second control group (referred to as the non‐notification group) was composed of 155 offenders (37 level 1 and 118 level 2) released between 1997 and 2002 who were not subject to broad community notification. The results from the Cox proportional hazards models reveal that broad community notification significantly reduced the risk of time to a sex reoffense (rearrest, reconviction, and reincarceration) compared with both control groups. The findings were mixed, however, for both non‐sex and general reoffending. Whereas broad community notification significantly reduced the risk of timing to both non‐sex and general recidivism compared with the prenotification group, no such effects were found in the non‐notification group analyses. We discuss the implications of these results and attempt to explain why Megan's Law seems to reduce sex offense recidivism in Minnesota.     

Sexual offenders discharged from prison in England and Wales: A 21‐year reconviction study

Purpose. This study examined the reconviction rates of a cohort of sexual offenders released from prison in England and Wales during 1979. A 21‐year follow‐up period was used and sexual, violent and general reconvictions assessed. Method. The sample consisted of all adult male sexual offenders discharged from prison in England and Wales during 1979 (N = 419). Criminal conviction histories were obtained for the sample from the Offenders Index and sexual, violent and general reconvictions were calculated, over a period of 21 years (1979‐2000). Results. A quarter (24.6%) of the sample received a reconviction for a sexual offence over the 21‐year follow‐up period, 21.7% received a violent reconviction and 61.8% received a general reconviction. A proportion of the sample received their first sexual reconviction 5, 10 or 15 years after being discharged from custody, thus remaining at risk of reconviction for many years. Conclusions. The findings from this study give a unique insight into the long‐term offending of discharged sexual offenders in England and Wales and have implications for the supervision of such offenders.     

Methodological considerations in the evaluation of offender interventions: the problem of attrition

Attrition from offender interventions presents methodological problems when the effectiveness of the intervention is under evaluation. This article proposes a treatment-received (TR) design, which incorporates one-to-one matching on criminogenic variables. This design permits the comparison of completer, noncompleter, and nonstarter groups with their paired comparisons and, hence, allows a more accurate evaluation of program completion and noncompletion effects. A sample of 173 offenders, referred to one of two general offending behavior cognitive skills programs within community settings, was matched one-to-one by criminogenic variables to offenders from an appropriate comparison group. Reconviction analyses were undertaken using intention to treat (ITT) analysis, TR analysis using the full comparison group, and TR analysis using matched comparison groups. The ITT design found no impact of group membership on reconviction. The TR designs, however, provided evidence of moderate effects of completion: For every three completers, five of the matched comparison group members were reconvicted. The analysis also suggested a noncompletion effect: Noncompleters were twice as likely as their matched comparison group to be reconvicted.     

The importance of appropriate allocation to offending behavior programs

This study examined the impact on reconviction of appropriate allocation to three general offending behavior programs involving adult male offenders in the English and Welsh Probation Service. Appropriate allocation was defined by level of risk for reconviction. There were three allocation groups: too low, appropriate, and too high. Using a quasi-experimental design, the reconviction rates of offenders who were allocated to and completed a program, offenders allocated to a program who failed to start, and a comparison group were compared. It was found that the appropriateness of allocation affected reconviction independently of treatment group. Furthermore, in line with the risk principle, there was an interaction between treatment group and the appropriateness of allocation.     

Neuropsychological and Criminological Features of Female Homicide Offenders

Few studies have examined life history and cognitive characteristics unique to female homicide offenders. Understanding these characteristics could aid in risk assessment for extreme violence in this group of offenders. The current study utilized t‐tests or chi‐square tests to compare 27 female and 81 male homicide offenders on psychiatric, neurologic, criminal, and cognitive characteristics. Additionally, we explored the role of abuse history in female offenders through Kruskal–Wallis or Fisher's exact tests. Results indicate that in comparison with male counterparts, females are more likely to have history of mood disorder, borderline personality disorder, and abuse. Cognitively, female homicide offenders exhibit circumscribed cognitive impairment in verbal abilities and perform similarly to male homicide offenders across most cognitive tasks. Within the female offender group, history of sexual abuse is associated with higher rates of impulsive homicide and poorer verbal abilities. These findings provide preliminary evidence for distinct factors associated with homicide in women.     

How long did it last? A 10-year reconviction follow-up study of high intensity training for young offenders

Objectives

Most research has suggested that correctional boot camps are not very successful in reducing reoffending, but recent evidence has been more encouraging for programs that include significant rehabilitative components. In line with this, High Intensity Training (HIT) for offenders aged 18–21 at Thorn Cross Young Offender Institution in England was followed by a significant reduction in the number of reconvictions in a 2-year follow up. This article aims to evaluate the impact of the HIT program after 10 years.

Methods

The evaluation used a quasi-experimental design in which male young offenders who received HIT were individually matched, on their risk of reconviction, to a comparison group who went to other prisons. Official reconviction data, including the prevalence, frequency, types, and costs of offenses were used as the outcome measures.

Results

Offenders who received HIT had a significantly lower prevalence and frequency of reconvictions, but their superiority over the control group reduced over time (after about 4 years). However, the cumulative number of convictions that were saved increased steadily over time, from 1.35 per offender at 2 years to 3.35 per offender at 10 years. The cumulative cost savings also increased over time, and the benefit:cost ratio, based on fewer convictions, increased from 1.13 at 2 years to 3.93 at 10 years.

Conclusions

The beneficial effects of the HIT program became more obvious over time. More randomized experiments and long-term follow-up research, including regular interviews, are needed to evaluate the cumulative and persisting effects of correctional interventions more accurately.     

Psychopathy,expert testimony,and indeterminate sentences: Exploring the relationship between Psychopathy Checklist‐Revised testimony and trial outcome in Canada

Purpose. Psychopathy, as measured by the Hare Psychopathy Checklist‐Revised (PCL‐R), has the potential to inform judges attempting to preventatively detain Canada's highest risk offenders. However, studies examining the stigma of the psychopathy label give reason to exercise caution when expert witnesses introduce PCL‐R scores into their testimony. Methods. Judges' written or oral judgments were gathered from a publically available database in Canada. Dangerous offender hearings (N = 136) were examined to determine how factors within expert witness testimony were related to sentences of indeterminate or determinate length. Results. Results show a trend for PCL‐R scores to be related to trial outcome. Specifically, psychopathy diagnoses were correlated to experts' ratings of treatment amenability which were in turn related to trial outcome. In addition, experts tended to show partisan allegiance in the way they scored offenders on the PCL‐R. Conclusion. Discussion advocates a measure of caution when using PCL‐R testimony in an adversarial court context. Further research clarifying the role psychopathy plays in court decisions is also encouraged.     

Assessing crossover in a sample of sexual offenders with multiple victims

Purpose . This study examined the proportion of sexual offenders in England and Wales who exhibited ‘crossover’ in their choice of victim, as defined by age, gender and relationship to the offender. It subsequently aimed to identify criminal and demographic variables predictive of crossover. Method . The sample comprised 1,345 adult male sexual offenders. All had offended against multiple victims and had been discharged from custody in England and Wales between 1992 and 1996. Offence summaries within police records were used to collect victim details for each sexual conviction for each offender, and criminal conviction histories were obtained from the Offenders Index for the sample. Results . A quarter of the sample (24.5%, n = 330) demonstrated crossover behaviour in regard to at least one of the victim dimensions examined (i.e. age, gender or relationship). Using the risk predictor Static‐99, these offenders were found to be significantly riskier than those who did not display crossover behaviour. Multinomial regression failed to identify reliable variables predictive of crossover. Conclusions . The findings from this study are likely to represent an underestimate of the prevalence of crossover within sexual offenders in England and Wales. Reasons for this are discussed, and the implications of crossover for offender risk assessment, treatment, community supervision and policing practices are explored.     

An evaluation of the Enhanced Thinking Skills (ETS) programme with mentally disordered offenders in a high security hospital

Purpose. Further to evidence of the successful application of cognitive skills programmes with offenders in HM prison service, the Enhanced Thinking Skills (ETS) training course is now delivered in various secure forensic hospitals, and its usefulness with an offender patient population merits examination. Our aim was to evaluate the impact of ETS using measures designed to capture change in key areas targeted by the course, and a more global measure of mental well‐being. Methods. Offender patients (N = 83) referred for ETS between 2001 and 2006 via a wider groupwork service within a high security hospital were administered questionnaires before and after the training course, which was minimally adjusted to meet the needs of the patient population. Attendance rates, including ‘drop‐out’ (completion of 10 or less sessions) were recorded. Demographics by subgroup (completers vs. non‐completers), and the clinical significance of any changes endorsed by participants post‐group were examined. Results. ETS completers were significantly more likely than non‐completers to endorse changes in thinking style (e.g. a reduction in post‐course scores). Significant differences were observed at both the group and individual level in the direction of less externalization of blame, a slight increase in tolerance of frustration, an increase in social conformity, and improvement in critical reasoning skills. Furthermore there was a reduction in the endorsement of aggressive solutions to social problems. Conclusions. These findings demonstrate a significant short‐term impact of the course for mentally disordered offenders with regards change in aspects of their thinking style and enhancement of their social problem solving skills. This profile lends some support to the provision of ETS within secure hospital settings.     

How useful are psychometric scores in predicting recidivism for treated sex offenders?

This study examined the relationship between psychometric test scores, psychometric test profiles, and sexual and/or violent reconviction. A sample of 3,402 convicted sexual offenders who attended a probation service-run sexual offender treatment programme in the community completed a battery of psychometric tests pre- and posttreatment. Using Cox regression, posttreatment scores on measures of self-esteem, an ability to relate to fictional characters, and recognition of risk factors were, individually, predictive of recidivism. When psychometric tests were grouped into dynamic risk domains, only the pretreatment scores of the domain labelled socioaffective functioning (SAF) predicted recidivism and added predictive power to a static risk assessment. The number of risk domains that were dysfunctional pretreatment also predicted recidivism outcome; however, this did not add predictive power to a static risk assessment tool. Possible explanations for the superiority of pre- over posttreatment scores in predicting reconviction are discussed, and directions for further research considered.
