Measurement of the effectiveness of sex offender treatment

The aim of this paper is to review various methods of examining treatment effectiveness. A number of research methods used to examine the overall effectiveness of sex offender treatment, such as random assignment, risk band analysis, and matched control groups are discussed. Each of these designs offer advantages, but also have methodological shortcomings. While there are those who feel that only the most scientifically rigorous methodology must be employed if one hopes to draw meaningful conclusions, others feel that less stringent criteria in terms of comparison groups can yield meaningful inferential results. As a means of overcoming some of the shortcomings of recidivism outcome studies discussed, we suggest that the examination of more proximate outcomes, such as change within treatment, provide a useful addition to studies of treatment effectiveness.     

A longitudinal examination of sex offender recidivism prior to and following the implementation of SORN

The goals of the present study were to examine the recidivism rates of two matched samples of sexual offenders, those released prior to and after sex offender registration and notification (SORN) in New Jersey. The pre-SORN group (1990-1994) included 247 offenders, while the post-SORN group (1996-2000) included 248 offenders. The longitudinal analysis demonstrated that for sex offenders released from prison both prior to and after implementation of SORN, there are clearly two distinguishable groups of sex offenders in relation to patterns of recidivism. More than three-quarters of sex offenders were identified as at low risk of recidivism, with low rates of repeat criminal offenses. By contrast, the high-risk group of offenders was not only more likely to commit future criminal offenses, including sex offenses, but they were also more likely to commit significantly more offenses and to do so fairly quickly following release. Analyses also include an examination of the influence of demographics, substance abuse and mental health issues, treatment history, sex offense incident characteristics, and criminal history on recidivism. Finally, SORN status was not a significant predictor of sex or general recidivism. The study limitations and policy implications are discussed.     

Does criminal offender treatment work?

In examining the effectiveness of offender treatment, this article attempts to integrate disparate bodies of knowledge. An overview of the effectiveness of offender treatment is presented. To put offender treatment into perspectives, the psychotherapy outcome literature for nonoffenders is briefly reviewed. The complexity of offender treatment is further explored by reviewing correlates and antecedents of criminality that include antisocial personality disorder, antisocial behavior in children, and substance abuse. Implications of the existing body of knowledge on future policy and more active involvement by psychologists are discussed.     

Spatial patterns of sex offenders: Theoretical,empirical, and practical issues

The aim of the current article is to review the theoretical, empirical, and practical issues related to the spatial behavior of sex offenders. After describing three theoretical models related to geographic profiling, empirical studies are presented that investigate the links between offender characteristics, modus operandi variables, and the distances traveled by sex offenders. Different spatial typologies of sex offenders and investigative strategies that take into account the spatial component of criminal behavior are discussed.     

New directions in offender typology design,development, and implementation: Can we balance risk,treatment and control?

It should come as no surprise that there is no “one-stop shopping” offender typology available that can identify the risk level, targeted treatment protocols, and control levels of the offender groups examined in this special issue: murderers, sex offenders, batterers, violent prisoners, and violent mentally ill offenders. We are in desperate need of further research establishing the links between offender risk level, offender treatment needs, and offender control requirements for each of these offender groups. This article provides a “state of the art” discussion of the key issues that must be addressed by policymakers, practitioners, and ultimately, the public, vis-à-vis the design, development, and implementation of typologies for each of these targeted groups of offenders. This is followed by our assessment of the lessons learned from the great prison classification experiment. We conclude by providing an assessment of new directions in the development of typologies of offenders and the communities in which offenders reside, based on the simple notion that offender change–not offender control–needs to be the primary focus of the next generation of correctional classification systems.     

Legal issues raised in treating sex offenders

For the past 50 years the criminal justice system has distinguished sex offenders from other criminals. This has resulted in their differential treatment, with the goal being to eliminate their inappropriate behavior. This article discusses the history and status of mentally disordered sex offender (MDSO) statutes. A review of the legal issues which arise when treating a sex offender without statutory authorization is provided. A discussion of problems raised in treating the offender on both an inpatient and outpatient setting is presented. The article concludes with an analysis of the legal problems confronting the treatment provider in working with this group of individuals.     

An examination of the assumptions of specialization, mental disorder, and dangerousness in sex offenders

Sex offenders have been singled out for differential treatment by the legal and mental health systems. This article attempts to inform law reform efforts and criminal justice mental health policy by examining the assumptions underlying differential legal and mental health treatment of sex offenders. These assumptions include the theories that sex offenders are mentally disordered and in need of treatment, specialists in sex crimes, and more dangerous than other criminal offenders. Empirical findings demonstrate that sex offenders are not specialists in sex crimes and are not mentally disordered. Examination of past research suggests that sex offenders are not at more risk than other criminal offenders to commit future sex crimes. Implications of research findings for selective prosecution of sex crime cases, mental health policy, sex offender legislation, and predictions of future dangerousness are discussed. Proposals for future research needs and law reform are presented.     

Brief anger interventions with offenders may be ineffective: A replication and extension

Anger-management interventions are widely delivered in the criminal justice and forensic mental health systems. Whilst previous research has generally supported the thesis that anger management is an effective intervention for anger problems in general there remains a need to determine its effectiveness with offender populations. This paper reports the results of a controlled outcome study of a 20 h anger-management program offered to offenders. Those receiving treatment showed improvements in their knowledge about anger, but showed little change on measures of anger and anger expression when compared to waiting-list controls. Scores on measures of treatment readiness and level of need for treatment were however, correlated with post-treatment improvement. These findings are discussed in terms of their implications for the assessment and selection of appropriate participants for offender anger-management programs.     

Wie kann man in der Sozialtherapie Therapieerfolg feststellen oder messen?

The tradition of social therapeutic evaluation research in Germany is as old as the institution of social therapy itself. Social therapeutic facilities constitute the royal road to correctional treatment in the German prison system providing an integrated approach for offender treatment by means of psychotherapy (mainly cognitive-behavioral), vocational and job training, social work and leisure time therapy embedded in a therapeutic community. It was generally expected that evaluation research would prove the effectiveness of this method and generate results for the advancement of offender treatment. However, research results have yielded only moderate findings concerning the effects of social therapeutic interventions. This article considers how the outcome of social therapy and offender treatment is measured. Fundamental methodological challenges that evaluation research has to face are identified. In addition, a short overview of recent results from a longitudinal evaluation study is presented to substantiate the dilemmas and solutions of evaluation research in this field. It is discussed why it is so difficult to provide evidence for effectiveness of correctional treatment and concluded that this can by no means lead to a renunciation of the correctional treatment approach.     

Correctional institution based sex offender treatment: a lapse behavior study

The correctional community has engaged in a surge of sex offender treatment programs, both within the confines of the correctional institutions as well as at the community level. While there has been an increase in efforts to assess the effectiveness of these programs the research has been hampered by inconsistency in appropriate outcome measures. The present study addresses these shortfalls, while focusing on the early behavioral lapse indicators. The study focuses on the premise that not all sex offenders lapse in similar manners, and that those with adult and statutory victims would show more impulsive-criminal trends in lapse behavior when compared to those with child victims. The results support the premise on several variables, but not on sexual deviancy.     

Child versus peer/adult offenders: A critical review of the juvenile sex offender literature

Sexual offenses are serious crimes and it is believed that adolescents perpetrate 20% of all sexual assaults and 50% of all child sexual abuse (Barbaree & Marshall, 2006). To better understand the etiology of juvenile sexual offending, researchers have explored differences between those who offend children versus those who offend peers/adults. This paper critically reviewed 21 studies that compared juvenile sex offenders who abused children with those who abused peers/adults on a variety of variables including victim, offense, and offender characteristics; psychosocial variables; and predictors and rates of recidivism. Strengths and weaknesses of these studies as well as future directions for the literature are discussed. Common methodological limitations of victim-age based comparisons of juvenile sex offenders included inconsistent definitions, low-powered studies, lack of standardized measures, and recidivism data based solely on conviction rates. Overall, many inconsistent findings limit our ability to give overarching conclusions; however, the research does suggests that not only is it important to examine child and peer/adult offenders, but mixed offenders (i.e., offender with both child and peer victims) as a distinct group need to be included in comparisons as well.     

Adolescent sex offenders with mental retardation: Literature review and assessment considerations

Working with adolescent sex offenders can be a difficult challenge. When an offender also suffers from mental retardation, this challenge increases. Unfortunately, this has been a largely ignored population, and clinicians working with this group often find little empirical work to assist them. Yet, many theorists posit that addressing sexual offending behavior when the offender is an adolescent may help prevent that behavior from continuing into adulthood. This is important because adult sexual offenders are often very difficult to treat. The current paper begins by reviewing literature on social deficits of individuals who have mental retardation. These deficits may contribute to aberrant sexual behavior among adolescents. The focus of the paper is then a review of literature on adolescent sex offenders, including those with mental retardation. We conclude this review with suggestions for assessment of adolescent sex offenders and with recommendations for future directions.     

Sex-role orientation and attachment styles of sex offenders

Given the increase of individuals who have a history of sexual offenses, there has been an increase in research on the etiology of sex-offending behavior. The present purpose was to evaluate the relationship between sex-role orientation and attachment styles of males who were sex offenders. Analysis yielded statistically significant differences between comparison (n = 22) and clinical groups (n = 21) in gender roles, with little sign of the androgynous gender type for sex offenders. The offender group showed significantly lower frequency of androgyny scores and significantly higher scores on feminine and undifferentiated orientations, supporting the theoretical view of sex offenders as being "cross-sex-typed." In addition, the sex offender group had a significantly higher mean score on anxious-avoidant relationship attachment. Based on the present findings, there appears to be a need to help sex offenders explore how their gender roles may relate to their sex-offending behavior and assist sex offenders in the development of adaptive relationships with reduced anxiety and ambivalence.     

Veränderungen kriminogener Faktoren bei Sexual- und Gewaltstraftätern in Sozialtherapie und Regelvollzug

In the evaluation of offender treatment programmes, recidivism is still the most common measure of success. However, positive effects concerning future delinquent behaviour do not prove that treatment led to changes in the targeted criminogenic risk factors. Furthermore, little is known about whether such changes differ among the various offender types. This study investigated changes in self-reported criminogenic personality patterns and cognitions in a sample of treated and untreated sexual and violent offenders. Specific prosocial changes in treatment targets, such as self-control, excitability and neuroticism were found but similar improvements were also found in untreated offenders. In addition, changes in measured risk factors did not differ between offender types, although self-control, aggressiveness and neuroticism showed significant interactions between offence type and treatment delivery. Whereas treated violent offenders exhibited more positive changes than untreated violent offenders, an inverse pattern was observed in the case of sex offenders. Minor specific treatment effects as well as the limitations of the administered psychometric instruments are discussed as possible explanations for these results.     

Pro-criminal attitudes,intervention, and recidivism

We review the recent research literature on pro-criminal attitudes (PCAs) as a causal factor of recidivism with a focus on studies on the effectiveness of offender treatment programs targeting PCAs to prevent recidivism. The main conclusions that can be derived from the literature are: (1) the evidence supports the hypothesis that PCAs are related to reoffending; (2) most investigated offender treatment programs tend to reduce PCAs, although the general lack of adequate control group designs does not rule out alternative explanations for this reduction; and (3) there is no conclusive empirical evidence that intervention programs designed to reduce PCAs are effective in reducing recidivism. Empirical research in this area lacks the theoretical and methodological rigor to test causal models of the influence of treatment on reducing PCAs, and effects of PCAs on recidivism. Limitations of the empirical evidence are related to inadequate research designs and/or suboptimal data analysis strategies. Recommendations concerning optimized research designs and data analysis strategies that are likely to provide more conclusive evidence on the relation of PCAs, PCA treatment, and recidivism are given.     

Characteristics of juvenile sex offending against strangers: Findings from a non‐clinical study

Previous studies of the characteristics of juvenile sex offending have been restricted to clinical samples (with convicted offenders undergoing treatment or assessment), which have several inherent limitations. To overcome these limitations victim allegations made to the London Metropolitan Police, UK, in 2001, of sexual assault by juvenile stranger perpetrators were sampled. The study aimed to determine more accurately the alleged nature of sex offending by this type of juvenile offender (aged less than 18 years) and to determine what factors were associated with the most serious cases of this type of aggressive behaviour. The most common offence characteristics were identified, and relationships between suspect and offence/victim characteristics were statistically tested. Offence seriousness, as indicated by physical violence and the occurrence of penetration, was significantly associated with an assault by a team of offenders, a young victim, and older juvenile offenders. The potential for predicting offender characteristics from offence characteristics was examined. Estimated offender age was significantly predicted by the absence/presence of penetration. An older juvenile offender was predicted by a penetrative attack. Aggr. Behav. 30:243–253, 2004. © 2004 Wiley‐Liss, Inc.     

Uses of rational emotive behavior therapy with juvenile sex offenders

Juvenile sexual offenses appear to be on the rise. This contributes to harm and trauma to the victims and the community at large. For many years the major interest in sex offender treatment has been directed toward assessment and treatment of the adult offender in spite of the reported large proportion of all sex crimes committed by juveniles (Uniform Crime Reports, FBI, 1985). Our article addresses three uses of Rational-Emotive Behavior Therapy (REBT): 1) in group and individual therapy, 2) in work with the offender's family, and 3) in staff training. The issues of the client's faulty learning and cognitive distortions is critical in the habilitation and rehabilitation process and may include such messages as: 1) I am powerless to control my sexual arousal, 2) I won't get caught if I am careful, 3) Masturbating about little kids is OK, 4) I need to feel better and when I am sexual with someone I feel better. This article will describe how the theory and practice of REBT (Ellis' 1984) is applied with juvenile sex offenders. A key feature is its use with the offending juvenile in the teaching of a rational belief system as well as ways to reduce emotional disturbances.     

Offending Patterns,Control Balance,and Affective Rewards among Convicted Sex Offenders

We present results from a survey of 125 incarcerated sex offenders enrolled in a residential sex offender treatment program that reveal their offending behaviors, reasons for offending, and the affective states they say they experienced while committing their crimes. We supplement this survey information with qualitative data from audio-taped focus groups with these same offenders. Results provide a unique glimpse of the self-reported offending patterns of these offenders, as well as characteristics of their victims and the relationship of the offenders to their victims. Employing concepts from locus of control and control balance perspectives, we argue that many sex offenders, particularly high-volume and high-frequency offenders, are motivated to commit crimes due to an externalized locus of control (a control deficit), which reflects a perceived lack of control over events in their own lives. Their crimes can be viewed as a strategy or device that allows them to experience positive affect and sensations of power and control—even if only temporarily. Findings with regard to offending patterns, motivations, and affective rewards common to these offenders lend qualified support to control balance theory and the locus of control concept and help us understand what drives people to commit sex offenses.     

Examining Predictors Which May Influence Sentencing Outcomes for Individuals Convicted of Offenses against Children: A Brief Report

Numerous studies examine sentencing decisions, yet little attention has been given to sentencing of child maltreatment and, more specifically, on variables that could impact sentencing outcomes for this form of criminality. Using Pennsylvania Sentencing Data for 2006, this research adds to the existing sentencing research by exploring predictors that might influence sentencing decisions for individuals convicted of crimes against children. The findings indicate that offender sex significantly affects the sentencing decision and offender age significantly affects sentencing length. In addition, all offense characteristics significantly influence the sentencing length decision. Implication of these results and directions for future research are discussed.
