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.     

Juvenile Sex and Non‐Sex Offenders: A Comparison of Recidivism and Risk

Forty male juvenile sex offenders were compared with 133 male juvenile non‐sex offenders 2 years postrelease from residential treatment to assess recidivism and factors related to recidivism. Juvenile sex offenders had significantly lower recidivism rates than juvenile non‐sex offenders.     

Can we profile sex offenders? A review of sex offender typologies

Sex offenders constitute a heterogeneous population of individuals and can be classified into typologies based upon characteristics and motivations of offending. The most common classification systems are those differentiating between types of rapists, child molesters, female sex offenders, juvenile sex offenders and cyber sex offenders. Understanding the characteristics and motivations of sex offenders can lead to more effective treatment, supervision and management of offenders. This article outlines the development of sex offender typologies over the last quarter century.     

The Role of Dehumanization in Attitudes Toward the Social Exclusion and Rehabilitation of Sex Offenders

We examined the role of dehumanization in people's attitudes toward the rehabilitation of sex offenders. In Study 1, the more participants dehumanized sex offenders, the less they supported their rehabilitation and the longer the sentences they recommended. In Study 2, the more participants dehumanized sex offenders, the more likely they were to support their exclusion from society. In Study 3, the more participants dehumanized sex offenders, the more they supported their violent ill treatment. In Study 4, within a sample of correctional staff, good quality contact with sex offenders was related to less dehumanization and more support for rehabilitation. Mediation analyses indicated that the relationship between quality of contact and support for rehabilitation was mediated via dehumanization.     

What is to be done? future research on the assessment and behavioral treatment of sex offenders

Much progress has been made in the assessment and treatment of sexually aggressive men. There remains, however, a great deal of work to be done. Future research should move on three fronts simultaneously: the extension and refinement of assessment methods which will serve to discriminate sex offenders from other persons and different sorts of sex offenders from each other, the further development of, and comparison among, treatment techniques designed to change sex offenders on relevant dimensions, and long-term followups of sex offenders who have been treated with different methods. Basic research concerning not only sex offenders but also the development of human sexuality is also required for the formulation of a theory which will guide future research.     

societal reaction to sex offenders: a review of the origins and results of the myths surrounding their crimes and treatment amenability

Examination of societal reaction to sexual offenders reveals a history of harshness exemplified by the sexual psychopath laws of the 1930s. The latest round of legal attempts to control sex offenders uses Severe sentencing laws, civil commitment procedures and community notification statutes to confine and shame sex offenders. This paper shows these laws to be based on popular beliefs about the predatory nature of these men, the probability of their re-offense and their amenability to treatment rather than the facts about the sex offenses and offenders. The severe reaction to sexual offenders is a vindictive one based on myth and misunderstanding that serves many interests. The paper exposes the contradictory myths and skewed emotions that guide our view of sex crimes and compares these with the facts about re-offense rates and the effects of treatment.     

Reinforcement sensitivity of sex offenders and non‐offenders: An experimental and psychometric study of reinforcement sensitivity theory

This study tested predictions of Gray's Reinforcement Sensitivity Theory (RST) in subgroups of sex offenders and male non‐offenders using an experimental choice task consisting of a reward and a non‐reward phase. In addition, RST‐related psychometric measures were used. Both experimental and psychometric data were of interest to determine whether sex offenders could be reliably differentiated from non‐offenders. Paraphilic (N=50) and impulse control‐disordered (N=48) sex offenders showed greater sensitivity to continuous reward than male non‐offenders (N=51). Impulse control‐disordered sex offenders showed less behavioural adaptation under non‐reward than both paraphilic sex offenders and male non‐offenders. In addition, reward sensitivity, rash‐spontaneous impulsivity, and anxiety measures discriminated sex offenders from male non‐offenders. The results suggest that reinforcement sensitivity is a promising personality trait for differentiating subgroups of sex offenders from non‐offenders. The experimental and psychometric results illustrate that predictive accuracy in forensic settings could be improved by combining several types of data.     

Treating the Troubled Family by Nathan W. Ackerman

Abstract

Group therapy is a widely accepted model of care for sex offenders. However, most group therapy takes place in prison utilizing a cognitive-behavioral, psychoeducational model of care. Given that over 250,000 sex offenders are in ambulatory treatment, newer models of care may need to be employed to address their specific needs. I present a naturalistic outpatient study involving my private practice of 109 consecutive sex offenders treated over a 10-year period. A multimodal model of care informed by psychodynamic theory is presented with detailed case material from one group session. Preliminary results of recidivism are presented.     

Rape and sexual assault in investigative psychology: the contribution of sex offenders' research to offender profiling

Research on sex offenders has mainly guided clinical practice for risk assessment and therapeutic intervention. However, the current scientific knowledge on these offenders and their crimes is, in many aspects, of great importance to criminal investigations. Consequently, there is a need to build bridges between investigative psychology and the research being conducted on sex offenders. Four areas of research on sex offenders that have clear implications to investigative psychology can be identified: (1) the consistency or ‘crime‐switching’ patterns of sex offenders; (2) the recidivism patterns of different types of sex offenders; (3) the police response to specific victim characteristics; and (4) the A → C equation of sexual assaults. This paper argues for a need to establish a dialogue between these two fields of research so that knowledge about sex offenders keeps growing whilst being able to inform policing practices in investigative psychology.

Psychopathie,antisoziale Persönlichkeitsstörung und Sexualdelinquenz

In today’s field of forensic psychiatry, psychopathy is seen as a subtype of antisocial personality disorder and includes manipulative behavior, egocentric and arrogant characteristics, high-risk behavior as well as a lack of empathy. Empirical data on the prevalence of psychopathy and antisocial personality disorder among offenders greatly vary depending on the study design and the composition of the sampled population. Offenders who committed both violent and sex offenses seem to have antisocial traits with a higher probability than offenders who committed only violent or only sex offenses. In the context of criminal responsibility and risk assessment for sex offenders, antisocial and psychopathic traits have a negative impact on the prediction of recidivism. Many study results, even though not all, additionally indicate that the combination of psychopathic traits and sexual deviance (i.?e. for example a paraphilic disorder such as sexual sadism) in sex offenders may be associated with a particularly high risk to reoffend. Due to the specific interpersonal characteristics (e.?g., dominant, provocative behavior, exaggerated self-esteem), therapeutic treatment of sex offenders with antisocial and psychopathic traits is often difficult. The regular supervision by the therapist is considered to be crucial to avoid harmful relationship dynamics or distorted perception of the therapist.     

The Impact of Risk Factors on the Treatment of Adolescent Sex Offenders

The authors investigated the impact that 5 selected risk factors have on the treatment outcome of adolescent male sex offenders. The results indicated that the greatest risk factor among sex offenders was having a mother who had a substance abuse problem.     

Sexually Violent Predators: Toward Reasonable Estimates of Recidivism Base Rates

The sexual recidivism rate of sex offenders is a controversial issue. Perhaps as controversial is the sexual recidivism rate of the select group of sex offenders who are examined pursuant to sexually violent predator (SVP) statutes. At present, reliable estimates of SVP recidivism are unavailable. We propose that reasonable estimates of SVP recidivism can be reached by considering three available pieces of data: (i) a likely recidivism rate of the general population of sex offenders; (ii) procedures typically followed by jurisdictions that civilly commit sex offenders; and (iii) classification accuracy of procedures. Although sexual recidivism rates vary across jurisdictions, the results of our analyses suggest sex offenders referred for examination pursuant to SVP statutes recidivate at substantially higher rates than typical sex offenders. Our results further suggest that sex offenders recommended for commitment as SVPs recidivate at even greater rates than SVP respondents who are not recommended for commitment. We discuss practice and policy implications of these findings. Copyright © 2013 John Wiley & Sons, Ltd.     

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.     

“Motivation” and Routine Activities Theory

ABSTRACT

This study examines the motivation aspect of routine activities theory as it pertains to sex offenders. Using logistic regression, data from 163 convicted sex offenders who participated in treatment programs between 1982 and 2000 were analyzed to determine if demographic, abuse histories, sex abuse histories, drug/alcohol use, and other “motivating” variables were predictive of in and out of the home offending. Results indicate abuse and drug use are predictive of home sex offenses while alcohol use is indicative of community offending. While the results and differences were modest, they warrant further exploration of the motivation aspect of routine activities theory.     

Unravelling Crime Series Patterns amongst Serial Sex Offenders: Duration,Frequency, and Environmental Consistency

Crime linkage and the investigation of behavioural consistency amongst serial offenders has been a flourishing field of research over the past decade or so, especially with respect to serial sex offenders. The emerging research in this field has often portrayed serial sex offenders as a single, distinct, and homogeneous group. Such an assumption, however, has never been empirically examined. Using a criminal career approach and a sample of 72 serial sex offenders who have committed a total of 361 sexual assaults on stranger victims, the current study aims to examine and describe subgroups of crime series patterns amongst serial sex offenders in terms of duration and frequency of offending. The level of environmental consistency display (i.e. offender's choice of crime location and characteristics of the crime site selected) across subgroups of crime series patterns is also examined. Study findings suggest the presence and heterogeneity of crime series patterns amongst serial sex offenders, advocating for the consideration of subgroups of crime series patterns when studying serial sex offenders. Moreover, the offenders' level of environmental consistency varies across the different crime series patterns identified, allowing for the identification of subgroups of offenders showing a higher or lower level of environmental consistency.

Denial and minimization among sex offenders

A review of empirical studies of offenders—particularly sex offenders, and more particularly those who offend against children—demonstrates that denial of offenses and minimization of offending behavior are quite common at every stage of the criminal justice process. This is true during police interviews, during pretrial and presentencing mental health evaluations, among incarcerated offenders, among offenders seeking treatment, among offenders facing parole review, and among offenders already released into the community. This review highlights gaps in the research literature arising from inconsistencies in the definitions and measurement of denial and minimization, from the stage of adjudication or treatment at which measurements are made, and from the use of polygraphy to increase disclosures. Despite these limitations on the generalizability of empirical findings, it appears beyond dispute that many sex offenders maintain their innocence in the face of evidence to the contrary or even criminal conviction, and that many are able to recite additional crimes they have committed when they believe it is in their self-interest to do so.     

Treatment of non-incarcerated sexually compulsive/addictive offenders in an integrated, multimodal, and psychodynamic group therapy model

Group therapy is a widely accepted model of care for sex offenders. However, most group therapy takes place in prison utilizing a cognitive-behavioral, psychoeducational model of care. Given that over 250,000 sex offenders are in ambulatory treatment, newer models of care may need to be employed to address their specific needs. I present a naturalistic outpatient study involving my private practice of 109 consecutive sex offenders treated over a 10-year period. A multimodal model of care informed by psychodynamic theory is presented with detailed case material from one group session. Preliminary results of recidivism are presented.
