Elderly sexual offenders: two unusual cases*

The aim of this case report is to describe two cases of sexual abuse by elderly subjects for which the Judge commissioned an expert psychiatric-forensic opinion. The elderly are generally believed to commit nonviolent crimes, whereas the two cases we observed feature forcible rape committed by elderly offenders, who showed no form of mental disease and had rationally planned their offense. They had never previously committed similar acts and had no history of homosexuality; both had been married for many years before the death of their wives and had adult children. Finally, no previous episodes of rape emerged in their personal histories during interrogations. The sociocultural context in which the crimes were committed was identical and arouses interest as regards both the method employed and how the crimes were discovered. The legal authorities then commissioned accurate investigations including medicolegal and psychiatric-forensic evaluations of the offenders and their victims.     

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.     

Revisiting the use of pornography by sexual offenders: Implications for theory and practice

Abstract

Summary: This article examines the extant research on the use of pornography by sexual offenders and some of the debates engendered by such use. The analyses should assist in clarifying a number of issues of concern for all who work in the field of sexual offending.     

Sleep apnea as a possible factor contributing to aggression in sex offenders

Sleep disorders, such as obstructive sleep apnea (OSA), are often unrecognized and undertreated. A disruption in normal sleep may be associated with increased irritability and aggression. To elucidate further the impact of OSA on hostility of forensic patients, we performed a retrospective chart review of 10 consecutive outpatient sex offenders who were diagnosed with OSA and treated with continuous positive airway pressure (CPAP). The Buss-Perry Aggression Questionnaire was compared pre- and posttreatment. Following treatment, the total Buss-Perry score was significantly lower, with lower scores on the anger, physical aggression, hostility, and verbal aggression subscales. These results suggest that in sex offenders suffering from OSA, aggression and hostility may be significantly reduced through CPAP treatment. Further investigation is required to investigate if reducing aggression and hostility in this manner impacts recidivism and overall functioning.     

The highs and lows of working with sexual offenders: A New Zealand perspective

Abstract

The positive effects on clinicians responsible for the treatment of sexual offenders are little understood. The few available studies have focused upon the negative sequelae of this work. The current study of clinicians working therapeutically with sexual offenders at a community-based organization aimed for a more balanced picture of the effects of sex offender treatment provision. Using qualitative methods, both negative and positive aspects of this work emerged within three main themes: taking an optimistic perspective, working for community outcomes and supportive agency culture. Although the study revealed many challenges for therapists, these were found to be counterbalanced against rewards, affording a high degree of personal and professional fulfilment from working within this field.     

The paraphilia-related disorders: an investigation of the relevance of the concept in sexual murderers

Paraphilic disorders (PAs) and sexual preoccupation are known risk factors for recidivism in sexual offenders. Nonparaphilic sexual excessive behaviors-so-called paraphilia-related disorders (PRDs), like paraphilias, are also characterized by sexual preoccupation and volitional impairment and can be diagnosed in paraphilic men. The prevalence and clinical significance of PRDs in sexual homicide perpetrators, however, is unknown. We investigated the relationship between PAs and PRDs retrospectively in a sample of 161 sexual murderers. Four groups were compared: men without a PA or a PRD diagnosis, men with at least one PRD but no PA, men with at least one PA but no PRD, and finally, those with a combination of both (PA+PRD). The PA+PRD group had the most lifetime cumulative sexual impulsivity disorders, more developmental problems, the highest persistent frequency of sexual activity, the highest number of previous sexual offences, more sexual sadism, and compulsive masturbation. Men of the PRD subsample had suffered more from childhood sexual abuse, showed more promiscuity, psychopathy, and alcohol problems. The use of the PRD concept in this special offender group should be further investigated with prospectively designed studies.     

Young adult sexual offenders with emerging personality disorders: developmental and offence-related characteristics and treatment engagement

ABSTRACT

In the context of the UK Government’s Offender Personality Disorder (OPD) Strategy, large numbers of high-risk young adult sexual offenders with emerging personality disorders are being screened for inclusion onto specialist intervention pathways (the OPD Pathway). However, little is currently known about the clinical and offence-related needs of this population or their impact on treatment engagement. The current study investigated the developmental, personality and offence-related characteristics of 87 incarcerated young adult sexual offenders, comparing those screened in to the pathway and those not screened in. Fifty per cent of the sample were potentially eligible for the OPD pathway. OPD eligible cases were found to have significantly higher rates of parental difficulties, developmental trauma, and childhood behavioural difficulties and to present with significantly higher rates of previous violent and sexual offences, previous allegations of sexual offences, and to have used physical coercion in their offences. The OPD sample was also significantly less likely to have pre-pubescent victims and more likely to refuse treatment, with over 70% failing to engage with the Sex Offender Treatment Programme (SOTP). SOTP non-engagement among OPD cases was most strongly predicted by categorical offence denial. Comparisons are made with the broader adolescent sexual offender literature.     

Using wilderness therapy in treating adolescent sexual offenders

Abstract

This article describes a follow-up study of 14 adolescent sexual offenders who had attended a community treatment programme. A core component of their treatment included outdoor wilderness group therapy. Interviews were conducted with adolescents and parents and tapped several areas including social skills and peer relationships, victim empathy, cognitive distortions, safety plans and coping with high risk situations, sexual offending cycle, perceived level of risk, intimacy and sexuality. The study also examined the child protection service records of the It adolescents. Data from child protection service computer records showed that none of the adolescents had reoffended. Interviews with adolescents and families focusing particularly on the wilderness component of the programme showed positive changes.     

Review on female sexual offenders: findings about profile and personality

Introduction

Although in the past sexual abuse was perceived as an issue connected only with males the contemporary literature is placing increasing emphasis on the role of female sexual perpetrators. There is still disagreement about the definition of sexual abuse, the frequency that it occurs and the characteristics of the women that are sexual abusers.

Methods

Thorough research of the main databases (MEDLINE and PsycInfo), for case reviews and studies along with restriction on European and North American literature, is due to perceived culture differences. Further investigation for relevant studies through web search engines such as Google, locates agencies and organizations that are interested and connected to sexual abuse issues.

Results

Distinction between sexual offense and sexual abuse has as a result difference in the characteristics of female sexual perpetrators. They are mainly young (age up to 36 years old), friends or relatives of the victim, using more persuasion and psychological coercion and legally charged in a lesser extent compared with male abusers. However the psychological consequences for the victim can be more severe.

Conclusion

A unanimous view of what is female sexual abuse is difficult to reach. Often it is under reported, unrecognized or considered ethically more acceptable than male abuse. It is also connected with an increased self-report of history of sexual abuse of the perpetrators. A typology of female sexual abusers should be developed. Treatments focusing on different psychological interventions along with prevention and public awareness can be a powerful tool in reduction of sexual abuse perpetrated by females.     

Evaluation of Purkait's triangle method for determining sexual dimorphism

The identification of sex from the skeleton is an important demographic assessment in medicolegal investigations. Rama Purkait developed a method for estimating sex using measurements from a triangle defined by three points on the proximal end of the femur using skeletal material from Bhopal, India. This method was tested with measurements on 200 Indo-European and African American adult femora from the Terry collection using discriminant function analysis to determine if Purkait's method was valuable for determining sex in Americans. A side-by-side analysis was conducted of Purkait's "triangle method" and the maximum diameter of the femoral head to determine their relative value in assessing sexual dimorphism. In the study sample a single variable from Purkait's method provided 85.5% prediction accuracy, similar to 87% for the head diameter. Combining threshold values for a single variable from Purkait's method and the femoral head diameter raised the predictability to greater than 90% for both sexes.     

Alcohol and drug consumption among sexual offenders

Purpose

To evaluate the role of alcohol and drug consumption between sexual offenders against boys and girls.

Method

It was an observational, retrospective and cross-sectional study carried out by the Ambulatory for the treatment of sexual disorders of ABC Medical College, Santo André, São Paulo, Brazil (ABSex). The sample comprised 104 convicts, over 18 years old, sentenced only for sexual crimes against children (below 11 years old). Alcohol and drug consumption, sexual abuse history, sexual impulsivity, and risk of recidivism were evaluated.

Results

The sexual offenders against boys showed higher alcohol consumption problems than sexual offenders against girls (χ² = 19.76, 1 d.f., p < 0.01). The severity of alcohol consumption was also significantly higher in the sexual offenders against non-related boys than in the sexual offenders against non-related girls (p = 0.037, ANOVA). After adjustment for other variables, such as monthly income before the penalty and alcohol consumption at the moment of the crime, the alcohol consumption severity in sexual offenders against boys was significantly higher than in sexual offenders against girls (OR = 1.05, CI 1.01–1.08, p < 0.01).

Conclusions

Alcohol use or abuse is associated with the perpetration of sexual aggression. The role of alcohol consumption seems to be greater in sexual offenders against boys than in girls and this can contribute to criminal recidivism.     

Development of the supernormality scale-revised and its relationship with psychopathy

Abstract:  The current research addresses the psychometric and diagnostic qualities of the Supernormality Scale-Revised (SS-R), a self-report measurement. Supernormality is defined as the tendency to systematically deny the presence of common symptoms (e.g., intrusive thoughts). In study 1, the SS-R was administered to forensic patients ( n  = 63), psychiatric patients ( n  = 26), honestly responding students ( n  = 26), and students instructed to fake supernormality ( n  = 20). Findings indicated good test–retest stability, and adequate internal consistency. Furthermore, the SS-R showed overall good predictive and convergent validity. Moreover, the diagnostic accuracy was excellent (sensitivity and specificity being 0.80 and 0.92, respectively). In study 2, 115 (healthy) controls and 32 forensic patients completed the SS-R and the Psychopathic Personality Inventory (PPI) ( J Pers Assess 1996; 66 :488), an instrument measuring psychopathy. Results showed again that the SS-R is a reliable and valid instrument. However, supernormality was not related to psychopathy as measured by the PPI.     

The effects of visual priming on information processing in child sexual offenders

Abstract

Child sexual offenders are hypothesized to hold offence-supportive beliefs that set them apart from others. The current study seeks support for this view via a cognitive-experimental approach. Child sexual offenders and offender controls were exposed to pictures of semi-clothed children (priming condition) or clothed, mature adults (control condition). Participants then read ambiguous sentences describing children's actions that could be interpreted in a sexualized manner. Next, participants completed a surprise recognition test in which half the sentences were re-presented in an unambiguously sexual form, and half in an unambiguously non-sexual form. Contrary to hypotheses, primed and/or control child sexual offenders did not show a memory bias for sexualized sentences, suggesting that they did not interpret the original sentences in line with offence-supportive beliefs. Results raise questions about whether child sexual offenders universally hold abnormal beliefs that facilitate their offending. Results also highlight the need for further experimental research within this field.     

An estimate of the proportion of drug-facilitation of sexual assault in four U.S. localities

In recent years, drugs including flunitrazepam, gamma-hydroxybutyrate, ketamine, and ethanol, have become popularly associated with drug-facilitated sexual assault. Other drugs are also candidates as factors in "drug facilitated sexual assault" (DFSA). The true extent of DFSA is not known, and is difficult to estimate. We recruited sexual assault complainants at four clinics in different parts of the U.S. to anonymously provide urine and hair specimens, and to answer questions about suspected drugging, drug use, and the sexual assault incident. Urine and hair specimens were tested for 45 drugs, including ethanol, and those pharmacologically capable of inducing sedation, amnesia, or impairment of judgment. Analytical test results were used to estimate the proportion of subjects, and the proportion of all complainants to the clinic in the same time period, who were victims of DFSA. Overall, cases of 43% of 144 subjects, and 7% of 859 complainants, were characterized as DFSA. Subjects underreported their use of drugs. The role of toxicological results and history in characterizing DFSA cases is discussed.     

Socially desirable responding and psychometric assessment of dynamic risk in sexual offenders against children

Does socially desirable responding (SDR) represent a threat to the validity of dynamic risk assessment in sex offenders’ self-reports? We studied a sample of men (N?=?218) who completed a psychometric assessment battery while enrolled at Kia Marama, a prison-based treatment program for sexual offenders against children. SDR, as measured by the Marlowe-Crowne scale, was elevated compared to non-offender samples, increased from pre- to post-treatment, and was negatively correlated with dynamic risk (rs?=??.30 to ?.40), consistent with previous research. Measures of dynamic risk factors derived from the psychometric battery were correlated with sexual recidivism, but correlations were little changed when variance associated with SDR was removed using a regression procedure [Mills, J. F., &; Kroner, D. G. (2006). Impression management and self-report among violent offenders. Journal of Interpersonal Violence, 21(2), 178–192.]. These results suggest that there is a substantial component of the variance in psychometric self-reports of sexual offenders that is associated with SDR (approximately 10%), but that it does not compromise the predictive or construct validity of dynamic risk measures derived from these reports.     

A case of stalking in the workplace and subsequent sexual homicide

A case of stalking in the workplace and subsequent sexual homicide by a 33-year-old male is reported. Following several months of stalking a 38-year-old female, the male subject went to the woman's office after business hours and restrained, raped, and murdered her. The cause of death was multiple stab wounds. The facts of the case reveal that the subject fits a predatory-type stalker, which represents a small subgroup within stalkers that has received little attention. Unlike other types of stalkers, the predatory stalker gives little warning to their victim (or multiple victims), as their stalking behaviors tend not to be very invasive or harassing. In general, most stalkers are not physically violent; however, predatory-type stalkers, given their tendency for sexual violence, are dangerous and the importance of identifying them is emphasized. Factors associated with perpetrators of sexual homicide are discussed.
