Static risk factors predict sexual misconduct among incarcerated female sexual offenders

Abstract

Although there has been a great deal of research conducted on sexual offenders in recent years, the vast majority of studies have focused on male perpetrators. Little is known about female sexual perpetrators, due primarily to the small number of offenders/offences and sociocultural factors. This study evaluated if there was an association between static risk factors [as delineated by the Static-99 and Rapid Risk Assessment for Sex Offender Recidivism (RRASOR)] and institutional sexual misconduct for incarcerated female sexual offenders. In addition to demographic information, total Static scores were obtained from a file review along with institutional conduct reports. The STATIC-99 and RRASOR scores from intake information significantly predicted sexual conduct reports in prison.     

Powerful perpetrators,hidden in plain sight: an international analysis of organisational child sexual abuse cases

ABSTRACT

There is virtually no literature on child sexual abuse committed by “powerful perpetrators”, who, use position, reputation, wealth and/or power, to become influential members of their organisation. Seventeen cases relating to youth serving organisations were identified using a comprehensive search of databases covering case reviews from England, Australia and the US. A Quantitative Content Analysis was used to analyse the sample with a focus on identifying offenders’ “modus operandi”. Findings revealed a number of critical differences between powerful perpetrators and other child sexual offenders described in the literature. Findings are discussed in relation to their implications for creating safer youth serving organisations. In particular, focusing on educating YSOs to recognise and address risks posed by powerful perpetrators; expanding organisational safety policies and practices and taking steps to develop a strong, positive organisational safety culture are commended as key approaches.     

The Motivation Behind Serial Sexual Homicide: Is It Sex,Power, and Control,or Anger?*

Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented.     

Sociodemographic and diagnostic characteristics of homicidal and nonhomicidal sexual offenders

The aims of this study were to compare the prevalence of psychiatric disorders and "psychopathy" in homicidal and nonhomicidal sexual offenders and to investigate the specificity of previous studies on psychiatric morbidity of a sample of sexual murderers. Information from court reports of 166 homicidal and 56 nonhomicidal sex offenders was evaluated using standardized instruments (SCID-II, PCL-R) and classification systems (DSM-IV). Sexual murderers were diagnosed more often with a personality disorder (80.1% vs. 50%; p < 0.001), especially schizoid personality disorder (16.3% vs. 5.4%; p < 0.05), as well as with sexual sadism (36.7% vs. 8.9%; p < 0.001) and sexual dysfunctions (21.7% vs. 7.1%; p < 0.05). Additionally, they had more often used alcohol during the offense (63.2% vs. 41%; p < 0.05). The results indicate that sexual murderers have more and a greater variety of psychiatric disorders when compared to nonhomicidal sex offenders.     

Psychopathy and Sexual Sadism

Psychopathic personality disorder and sexual sadism share several common characteristics, such as emotional detachment from the suffering of others or the preparedness to inflict pain or injuries. Based on a sample of 100 male forensic patients (all of them sex offenders, half of them sadistic), the concept of psychopathy and sexual sadism as a unified construct was tested empirically. Pooling indicator variables for psychopathic and sexually sadistic disorders showed that a two-factorial solution yielded a better fit than a single-factor model. The two factors identified psychopathy and sexual sadism as separate latent variables. More specifically, the data were compatible with a path model in which affective deficits and behavioral disinhibition of the psychopathy domain are precursors to sexually sadistic conduct.     

The impact of disrupted caregiving for juvenile sexual offenders

ABSTRACT

Research that attempts to understand why young people commit sex crimes points to an array of family factors that may uniquely contribute to sexual offending over general juvenile delinquency. This study examines the potentially moderating role of disrupted caregiving in the relationship between offending and caregiver-child relationship quality. Two distinct moderators were tested: gender of caregiver and biological relationship between caregiver and child. Results indicate that juvenile sexual offenders have particularly poor relationships with their primary caregivers compared to incarcerated non-sexual offenders and community controls. Furthermore, sexual offenders with male caregivers were found to have lower relationship quality scores than sexual offenders with female caregivers. In contrast, sexual offenders raised by non-biological caregivers reported better relationship quality than did offenders raised by their biological parents. These findings suggest opportunities for early intervention, before caregiving is disrupted.     

To what extent does civil commitment reduce sexual recidivism? Estimating the selective incapacitation effects in Minnesota

PurposeThis study examines the selective incapacitation effects of civil commitment on sexual reoffending among 105 Minnesota sex offenders who were civilly committed between 2004 and 2006.MethodsThe Minnesota Sex Offender Screening Tool-3, a sexual recidivism risk assessment instrument, was used to estimate what the four-year sexual recidivism rate would have been for these offenders had they been released to the community. Integration of Survival with Quality of Life (iSQoL) software was used to extrapolate the survival curves over a 50-year period to develop a lifetime sexual recidivism estimate.ResultsIf the 105 civilly committed sex offenders had been released to the community, an estimated nine percent would have been reconvicted of a new sex offense within four years. Civilly committing these offenders therefore likely reduced the overall four-year sexual recidivism rate by 12 percent. The results further suggest that if these offenders had been released to the community, an estimated 28 percent would be rearrested for another sex offense within their lifetime.ConclusionsTo better align the costs of civil commitment with its public safety benefits, states operating these programs should emphasize the use of intermediate alternatives in the community for a more positive return on investment.     

Arbitrary decision making in the absence of evidence: an examination of factors related to treatment selection and recidivism for female sexual offenders

ABSTRACT

As criminal justice professionals are asked to assign risk levels and treat females who sexually offend, identifying risk factors for recidivism prediction and treatment targets is important. Although the majority of risk and treatment studies have focused on males, general female offender research and developing research with female sex offenders both provide some evidence for possible factors related to sexual offending behaviour in women. The purpose of this study was to explore what possible factors were related to treatment selection in a sample of 506 females serving prison sentences for a sexual offense, and, in turn, to examine which factors predicted non-sexual and sexual recidivism. Results demonstrated that exploratory variables were significantly related to treatment selection, as opposed to variables previously supported in research. Furthermore, living with a significant other for more than two years, and prior sexual offending arrests predicted sexual recidivism, while decreased age and treatment participation predicted non-sexual recidivism. These findings indicate that while similarities between male and female sexual offenders exist, females still demonstrate gender-specific risk factors.     

Social networks of sexual offenders

Abstract

Despite the extensive research attention directed toward criminal peer groups, there has been little attention to the peer groups of sexual offenders. Sexual offenders are often considered to be loners who offend in isolation, but cases of sex crimes involving peer support are not difficult to find, e.g., child sex rings, gang rapes. To examine the role of peers in sexual offending, sexual offenders and nonsexual offenders were asked whether they knew other people who have committed sexual crimes. In comparison to the nonoffender community comparison group, the sexual offenders reported considerably more association and identification with sexual offenders. The associations also tended to be offence specific, such that child molesters knew other child molesters and rapists knew other rapists. These findings have important implications for the assessment and treatment of sexual offenders.     

Severe Sexual Sadism—An Underdiagnosed Disorder? Evidence from a Sample of Forensic Inpatients

Abstract:  Severe sexual sadism is a disorder of sexual preference that focuses on humiliation and subjugation of the victim, sometimes causing grievous injury or death. Sexual sadists pose a particular risk. However, the diagnosis as such is unreliable and prevalence estimates vary. In a sample of male high-security forensic inpatients who had committed sexual offenses, we found two-thirds of sexual sadists had not been identified as such prior to commitment. Possible reasons for missing the diagnosis are many fold. Present data support the notion that unrecognized sexual sadists more closely resembled non-sadistic sex offenders than accurately diagnosed sadists. In particular, initially unrecognized sexual sadists had less severe previous convictions, less vocational training, and experienced a less supportive upbringing than their correctly identified sadistic counterparts. The latter, in contrast, more often reached media coverage through their offense(s). We conclude that severe sexual sadism is likely an underdiagnosed, yet forensically highly relevant disorder.     

Psychological profile of sex offenders using weapons in their crimes

Abstract

A sample of 1533 sex offenders was examined for clinical characteristics associated with weapon use in their crimes. A total of 24.9% used weapons, most often knives (50.1%), with 13.6% using multiple weapons. Weapon-users were a very disturbed group, who showed a significantly higher prevalence than non-users of psychoses, suicide attempts, alcoholism, drug addiction and abuse, personality disorders, psychopathy, attention deficit hyperactivity disorder, cognitive impairment and violent criminal histories. The weapon-users recidivated more often than non-users and appeared in court on 8.7 separate occasions compared to 2.9 for non-users in an average follow-up of 21.5 years. The best predictors of weapon use were total violent offence convictions, sadism diagnoses and adult versus child victims. The importance of examining weapon use in assessing sex offenders is discussed.     

Rosemary west: Motives and meanings

Abstract

This article originally appeared in Trouble and Strife (Winter 1996/97, pp 44-52) and is reproduced, by kind permission of the original publishers, as Deborah Cameron's thought-provoking analysis of the Rosemary West case is felt to deserve a wider audience.

In the article, Deborah Cameron reports that feminists were mostly silent about the Rosemary West case in spite of having an analysis of sex crime, because female perpetrators of sexual murder seemingly did not fit that analysis. She argues, however, that female sexual murderers can be understood within a feminist framework. Identifying Rosemary West as one of only a handful of female sexual murderers, Cameron theorises that Rosemary and Fred West, like other sexual murderers, were constructing a form of identity based on sexual transgression and existential transcendence, perhaps as a strategy for dealing with their own history of abuse. What Cameron also provides us with is an explanation for why sexual murderers are overwhelmingly male, an analysis based on an understanding of the context of patriarchy.     

How should we understand the effect of age on sexual recidivism?

Abstract

Research into the effect of age on sexual recidivism risk is a relatively new and developing area of interest and is likely to be of great interest for forensic practitioners responsible for the community supervision of sexual offenders. Meta-analytical and follow-up reconviction studies indicate an inverse relationship between age and sexual recidivism risk, where younger sex offenders pose a greater risk of reconviction than older sex offenders. This finding has led to the development of actuarial risk scales which identify younger sex offenders (<25 years) as posing the greatest risk. However, recent research studies have reported contradictory results to this assumption and found a non-linear relationship between age and sexual recidivism risk. Only a small number of studies have investigated the effect of age on sexual recidivism by comparing age bands and rates of sexual recidivism. Researchers have also considered the effect of age on actuarial risk, which risk factors are associated with which age bands and sexual recidivism rates between sex offender subgroups. The purpose of this paper is to integrate this research and to link commonalities between these studies. This paper organizes the effect of age on sexual recidivism into five categories: (i) the effect of age and actuarial risk; (ii) the effect of age on sexual arousal; (iii) the effect of age-at-release on sexual recidivism risk; (iv) the effect of age-at-first-offence on sexual recidivism risk; and (v) the effect of age on child molesters and rapists on sexual recidivism risk. Important differences were found between age bands of sexual offenders in terms of sexual recidivism risk and actuarial risk factors as well as differences between rapists and child molesters. The relative importance of factoring age when assessing risk in sex offenders is discussed.     

Risk assessment with intimate partner sex offenders

Abstract

Risk assessment with any offender presents a number of challenges. However, risk assessment with offenders who have committed offences against their partners presents practitioners with a number of additional challenges. Intimate Partner (IP) sex offenders are reported to be responsible for the majority of adult serious sexual offences in England and Wales. However, despite calls for a unified approach to sex offender theory there has been little integration between this and the IP and family sexual violence literature. This paper summarizes the relevant literature on prevalence and cross over of sexual abuse by IP offenders, patterns of abuse, generality of offending, psychopathology and risk concerns (including risk of intimate partner homicide). Based on this, recommendations are made for best practice with IP sex offenders.     

The long term recidivism risk of young sexual offenders in England and Wales– enduring risk or redemption?

PurposeTo examine the long-term sexual recidivism risk of juvenile sex offenders in England and Wales, and to compare the risk to that of a first time sexual offense for non-convicted juveniles. Additionally, the study explores the long term sexual recidivism risk of other types of juvenile offenders, and the long term violent recidivism risk of these groups.MethodsThe England and Wales Offenders Index was used to extract birth cohort data. Life table methods were used to estimate cumulative recidivism risk, and discrete time hazard models were used to compare hazard functions.ResultsAt the five year period, 7% of juvenile sexual offenders have been reconvicted of a sexual offense; reaching 13% by the end of the 35 year follow-up. When the reconviction hazard of the juvenile sexual offenders was compared with the first sexual conviction risk of a non-convicted comparison group, the hazards converged statistically after 17 years.ConclusionsThe study has implications for the registration periods of juvenile sex offenders. Indefinite registration for some juveniles needs to be considered, and a review of registration after a conviction free period would provide more balance between the protection of the public and the rights of the offender.     

Sexual offenders with learning disabilities: risk,recidivism and treatment

Abstract

While the literature on the assessment, treatment and management of non-learning disabled sexual offenders is well established, it is only in recent years that researchers and clinicians have focused on sexual offenders with learning disabilities. In contrast to mainstream sex offender treatment programmes, there are few evaluated community-based treatment programmes for sexual offenders with learning disabilities, and of the small number of published studies that describe treatment programmes, most are based on small samples and few have been validated empirically. Sexual offenders with learning disabilities differ from their non-disabled counterparts in several important ways, having implications for management and treatment. Due to methodological differences between studies, the prevalence of sexual offending by men with learning disabilities is not clear. However, in some studies, the sexual recidivism rate of offenders with learning disabilities is 6.8 times and 3.5 times that of non-disabled sexual offenders at 2- and 4-years’ follow-up, respectively. Sexual offenders with learning disabilities are also at greater risk of re-offending in a shorter time period. There remains an urgent need for further research into the assessment of risk and whether components from mainstream treatment programmes can be adapted to meet the needs of learning disabled sexual offenders. Approaches to working with sexual offenders with learning disabilities and programme development are discussed.     

Long-term follow-up of criminal recidivism in young sex offenders: Temporal patterns and risk factors

Abstract

Recent studies indicate that risk for criminal re-offending in identified adult sex offenders may persist decades after the index offence, calling for inquiry into these issues also for younger sex offenders. The author studied temporal patterns for criminal reconvictions and the validity of 16 empirically motivated risk factors for recidivism among all young sex offenders (15–20 years of age) subjected to pre-sentence forensic psychiatric evaluations in Sweden during 1980–1995 (N = 126). The Ss were followed from release and for an average of 115 months. One-hundred-and-seventeen (115 male, 2 female) Ss were available for follow-up with a mean time-at-risk of 80 months. Base rates for sexual and violent non-sexual reconvictions were 30% and 42%, respectively. Using time-at-risk-adjusted hazard ratios derived from Cox regression, characteristics indicative of deviant sexual interest (any previous sex offending behaviour, an index sex offence in a public area, involving a stranger victim, offending on two or more offence occasions, and two or more victims) were found to increase the risk for sexual recidivism. Markers of antisocial lifestyle (early signs of DSM-IV Conduct Disorder and any prior violent conviction), sex offence-related characteristics indicating aggression proneness (use of threats or force and physical victim injury), and victim penetration, increased the risk for violent non-sexual reconvictions. Survival analyses indicated that the rate of sexual reconvictions as a function of time at risk decreased distinctly after 6–7 years whereas the rate for violent non-sexual reconvictions remained largely the same.     

Victim empathy in young sex offenders in the emergent adulthood developmental phase

ABSTRACT

This article reports on a study which focused on young sex offenders’ empathy levels for sexual abuse victims in general as portrayed in a case study, as well as empathy for the offenders’ own specific victims. Beckett and Fisher’s Victim Empathy Distortion Scale (1994) was used to measure and compare 96 young sex offenders’ empathy levels. The quantitative research results indicated that research participants displayed significantly less empathy towards their own victims when compared to the empathy displayed towards a general sexual abuse victim in a case study. Following the completion of the questionnaires, in-depth, qualitative data was obtained regarding the young sex offenders’ thoughts prior to, during and directly after committing the offence. In addition, they also explained their current thoughts and feelings for the victims in their case. The divergent responses which were given by the participants is a clear indication of the heterogeneous nature of youth sex offending.     

Group size does matter: differences among sexual assaults committed by lone,double, and groups of three or more perpetrators

ABSTRACT

We compared a total of 340 sexual assault cases based on offender characteristics, victim characteristics, and offence behaviours to identify differences among sexual assaults committed by lone, double, and groups of three or more perpetrators in South Korea. Several differences were found among sexual assaults committed by varying numbers of offenders. First, lone, double, and groups of three or more perpetrators differed with respect to age, marital status, and employment status. Second, substantial differences in victim characteristics were observed with respect to age and the victim–offender (v–o) relationship. Third, significant differences in offence behaviours, including offence type, planning, method of approach, knife possession, and stealing property, were found. Furthermore, we identified several variables that significantly predict group size using logistic regression analyses. The study has theoretical implications for understanding how group dynamics influence the behaviours of rape perpetrators, and practical implications for victim treatment and offender intervention.     

What has worked and what has not with Minnesota sex offenders: a review of the evidence

Abstract

Since the early 1990s, many states in the USA have attempted to control sexual offending and, more narrowly, sexual recidivism by implementing longer prison sentences for sex crimes, sex offender registration and notification, residency restrictions, involuntary civil commitment and lifetime probation and parole. The early 1990s also marked the beginning of a decline in official rates of sexual offending, including sexual recidivism. This study reviews recent research conducted on Minnesota sex offenders in an effort to identify which policies, programmes and practices might have contributed to the drop in sexual recidivism rates that have been observed over the last few decades. By assessing what has, and has not, worked with Minnesota sex offenders, this study discusses how lessons learned from the Minnesota experience may apply to broader efforts within the USA and abroad to control sexual offending.
