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.     

Examining the relationship between sexual offenders and their victims: Interpersonal differences between stranger and non-stranger sexual offences

Abstract

The present study examined the behavioural differences in sexual assault offences in relation to the offender–victim relationship (stranger versus non-stranger). These differences were examined specifically in the context of four interpersonal themes of interaction: dominance, submission, hostility and cooperation. The details of 100 sexual offence cases (50 stranger and 50 non-stranger) were content-analysed, generating 58 dichotomous variables, covering offender and victim behaviour during the offence. χ² tests comparing the two samples found that offenders who were strangers to their victims were more likely than non-stranger offenders to display behaviours that indicate a hostile, violent offence style. In contrast, those offenders who knew their victims were more likely than strangers to display a less violent and more personal, compliance-gaining offence style. These findings are discussed in terms of their implications for offender rehabilitation and victim support.     

Self-serving aspects of social cognition among adult offenders

Abstract

The different cognitive beliefs about offending exhibited by offenders are discussed. The question addressed in this paper concerns the extent to which beliefs and social knowledge about offending differentiate between different characteristic types of offending (drug abuse, theft, sexual and violent). Two hundred and ninety adult male prisoners in four Taiwanese prisons provided self-reported criminal histories. From these a crime index indicative of the proportion of offences of each type (or specialism in offending) was calculated for each offender. Offenders legitimize their own offending while they tend to regard the offences of others negatively. In this way, cognitive representations may reinforce an offender's specific pattern of criminal acts while also insulating them from pressures towards other criminal activities. Evidence is presented that offenders' social knowledge development is consolidated around crime themes.     

Crime profiles and conditional release performance of psychopathic and non‐psychopathic sexual offenders

Purpose. This study investigated the influence of psychopathy and sex offender subtype on criminal history, probability of being granted conditional release, and performance while on conditional release in a diverse group of violent offenders. We predicted that psychopathic sexual offenders would be associated with relatively prolific violent and sexual offending, a high probability of successful conditional release applications despite their past behaviour (resulting from ‘putting on a good show’ in a parole hearing), and poor performance in the community. Methods. Information was gathered via a correctional file review of 310 Canadian male federal offenders. Offenders were categorized into groups based on their sexual offence history (non‐sex offender, rapist, child molester, or mixed rapist/molester) and Psychopathy Checklist – Revised (PCL‐R; Hare, 2003) ratings. Their offences (sexual, violent, or non‐violent) and their complete conditional release histories were coded. Results. Psychopathy was associated with more violent and non‐violent, but not sexual, offences. A significant interaction between psychopathy and offender subtype revealed that psychopathy was associated with a greater number of sex offences within child molesters. High‐psychopathy offenders (both sexual and non‐sexual offenders) were about 2.5 times more likely to be granted conditional release than non‐psychopathic offenders. Conclusions. Psychopathy is associated with more prolific sexual offending among child molesters and – despite their extensive criminal histories and high recidivism rate – a great proficiency in persuading parole boards to release them into the community. Specialized education and training in dealing with psychopathic offenders is urgently needed.     

International sex offender registration laws: research and evaluation issues based on a review of current scientific literature

In many jurisdictions, anyone convicted of a sexual offense is required to register with police, often for life. Nine different countries have now implemented sex offender registries in an attempt to protect the public from the perceived threat posed by sexual offenders. Yet such laws have been criticized as being overly inclusive, tying up limited law enforcement resources to track many offenders who pose little risk of sexual reoffending. This paper considers the available research evidence relevant to the effectiveness of such laws for the deterrence of sexual offending and the investigation of sex crimes. It is concluded that significant gaps persist in our knowledge of whether existing laws effectively reduce sexual offending or reoffending and that large-scale, well-designed studies of the impact of sex offender registration on rates of offending, the collateral consequences to offenders and their families, and the costs of such laws are needed.     

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.     

Offence characteristics and cognitive functioning in juveniles adjudicated for illegal sexual behaviour

Intelligence differences exist between sex offenders and non-sex offenders in adult populations, but comparable intelligence differences are not consistently found among juveniles. However, juveniles may differ on measures of intelligence across offence-related variables used to subclassify adults. The purpose of the present study was to determine if between- and within-group differences exist in a sample of 925 juveniles adjudicated for illegal sexual and non-sexual behaviours across offence-related variables. The results suggest that juveniles adjudicated for illegal sexual behaviour outperformed juveniles adjudicated for non-sexual offences on Wechsler Abbreviated Scale of Intelligence (WASI) performance, though full-scale intelligence quotients scores for both groups were lower than would be expected in the general population. Unlike adult offenders, juveniles adjudicated for illegal sexual behaviour do not tend to differ on WASI performance across offence-related variables. These results provide additional evidence that these juveniles adjudicated for illegal sexual behaviour are categorically distinct from adults who sexually offend.     

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.     

Responding to youth sexual offending: a field-based practice model that “closes the gap” on sexual recidivism among Indigenous and non-Indigenous males

Abstract

Most studies that have explored the impact of youth sexual offender treatment on recidivism have not assessed whether effectiveness varies for important subgroups. The present study evaluated the impact of treatment provided by the Griffith Youth Forensic Service (GYFS) on 104 adjudicated youth sexual offenders referred between 2006 and 2012. Sexual, violent and “other” offending outcomes were examined, based on Australian Indigenous cultural heritage and whether the youth resided in a remote community, over an average 2.5-year follow-up timeframe. The findings indicated that GYFS treatment was equally effective for Indigenous and non-Indigenous youth for preventing sexual recidivism and, for youth residing in remote and non-remote locations, for preventing sexual, violent and “other” recidivism. Treatment was less effective in preventing violent and “other” recidivism for Indigenous youth. The core components of the GYFS treatment programme therefore appear particularly well suited for reducing sexual recidivism by Indigenous offenders and those residing in remote communities.     

Sexual and violent recidivism by offender type and actuarial risk: reoffending rates for rapists,child molesters and mixed-victim offenders

Abstract

The current study examines sexual and violent reoffence rates for a sample of 2474 sexual offenders over an average of 15 years following release from prison. Reoffence rates are reported as a function of the offenders' victim type and level of risk as assessed by the Automated Sexual Recidivism Scale, a computer scored measure of relevant historical risk factors. Observed sexual recidivism rates for offenders with child victims, adult victims, and mixed victims were quite similar. Results indicate that offenders with exclusively female child victims not only showed a lower rate of sexual reoffending, but that the reoffence rates were relatively low across all levels of actuarial risk. In contrast, those with male child victims and adult victims showed a pronounced escalation of reoffence rates as actuarial risk increased. Results also indicated that adult victim offenders are less consistent in the victim type of their reoffences, with 37% sexually reoffending against child victims. Finally, combined rates of sexual and violent reoffending were particularly high for those with adult victim sexual offence histories. Risk assessment and public policy implications are discussed.     

Moroccan adolescent suspect offenders in the Netherlands: ethnic differences in offender profiles

Ethnic minority youths are over-represented in the juvenile justice system in Western societies. However, research on the nature of crime committed by these youths is lacking. In the present study, offending patterns of incarcerated native Dutch adolescents and adolescents of Moroccan origin were compared. Criminal record data were used to examine the offence history of 291 incarcerated adolescents. Offender types were determined through latent class analysis. Adolescents of Moroccan origin were incarcerated more often, for more offences and at a younger age than native Dutch adolescents. A four-class model of offender types was found: property offenders, violent offenders, sexual offenders and arsonists. Property offenders were mainly Moroccan adolescents, the other offender types consisted predominantly of native Dutch adolescents. Moroccan adolescents in pre-trial arrest in the Netherlands can be characterized as early starting offenders who persist in being incarcerated for property-based crime.     

Stranger rape: classifying Spanish sexual offences using multiple correspondence and cluster analyses

We have analysed the information in 342 police reports of stranger sexual offences recorded in 2010. We have carried out a multiple correspondence analysis and a cluster analysis using modus operandi variables to identify differential profiles in these types of sexual offences. We have come up with three profiles of stranger sexual offences, which concur in the two techniques used. By analysing the personal variables of the offenders with such profiles, we have found differences in terms of the offender’s country of origin and age. We will discuss the consequences of these results on the police investigation of stranger sexual offences.     

Low recidivism rates of child sex offenders in a Finnish 7-year follow-up

ABSTRACT

This study examines the recidivism rates of Finnish child sex offenders convicted in 2010 (n = 361) over a follow-up period of seven years. The results indicate that while reoffending for other types of offences was common (34%), offenders had very low sexual crime recidivism rates (1%). In terms of more persistent criminal careers, less than a quarter of the offenders had both a previous criminal history and at least one subsequent offence during the follow-up period. Offenders with child sexual abuse material-related crimes reoffended more rarely than did others. Study limitations and implications for policymaking, media and rehabilitation are discussed.     

Sexual coping,general coping and cognitive distortions in incarcerated rapists and child molesters

Abstract

Sexual coping, general coping and cognitive distortions were investigated in 25 rapists, 36 child molesters and 25 violent offenders. Rapists did not report more support for rape-supportive distortions than the violent offender comparison group. Child molesters scored higher than the other groups on the measure of molestation-supportive distortions, although mean scores were at the low end of the scale. Consistent with previous research, all offender groups reported ineffective coping styles and child molesters reported using more emotion-oriented coping than the non-sexual offenders. Child molesters but not rapists scored higher than violent offenders on deviant aspects of sexual coping, although mean scores were at the low end of the sub-scales. Evaluation of these comparisons was aided by effect sizes. The effect sizes reveal that there may indeed be differences between rapists and the comparison group with respect to cognitive distortions and sexual coping. Modest correlations were found between deviant sexual coping and cognitive distortions. The findings are interpreted in terms of etiological development and the sexual offence process.     

The internet and offending behaviour: A case study

Abstract

Summary: The COPINE Project at the Department of Applied Psychology, seeks to address children's vulnerability in relation to the Internet and child pornography. As part of the project, offenders convicted of downloading such images have been interviewed. This paper considers existing models of offender behaviour alongside literature relating to Internet use. A single case study is used to illustrate a process-focused model of offending, using interview material to demonstrate how the offender represented and accounted for his behaviour. The offender in question had no history of engaging in sexual behaviour with actual children, but his case illustrated many of the stages described by offenders in their involvement with pornography, including: setting events, engagement, collecting behaviour, and the emergence of relationships.     

Comparing Sexuality,Aggressiveness, and Antisocial Behavior of Alleged Juvenile Sexual and Violent Offenders,

Sexual delinquency in juveniles is insufficiently explored in regard to the specificity of offender characteristics. The aim is to investigate relevant areas for juvenile sexual offending in a precourt, pretreatment group. Thirty‐two alleged juvenile sexual offenders (ASO) referred to by police were compared with 32 juvenile nonsexual violent offenders (VNO) on standardized measures of aggressiveness and psychopathology, antisocial behavior, substance use problems, and sexuality. Less externalizing disorders and antisocial behavior were found among the ASOs than among the VNOs. The ASO group was sexually less experienced, had less trust in their relationship abilities, fewer victimization experiences, and reported more sexual deviance, while pornography use and obscene calls were reported less often. Few juvenile sexual offenders had severe problems in the investigated areas. Including groups of offenders before court, treatment or incarceration in research appears crucial to understand the full spectrum of sexual deviance in youth and avoid misguidance due to selection factors.     

The criminal career of men convicted of rape: evidence from a Norwegian national cohort

The extent to which sexual offenders are a group separate from other types of offenders has been debated for many years and investigated from different perspectives. The present study investigated similarities and differences regarding socio-economic background, criminal history and recidivism involving new crimes between rape offenders and three other groups: other sexual offenders, non-sexual violent offenders and other offenders. Data came from Norwegian population registers containing information on all crimes investigated from 1992 to 2012. The sample consisted of all persons convicted in 2002 and 2003 (N = 36,951). Background characteristics and estimated recidivism risk was described using hazard models. Results indicated that men convicted of rape (n = 142) had lower levels of education and that a higher percentage of them were on social benefits compared to the other crime groups. A large majority (79%) of rape-convicted men had previous convictions. Rape offenders were considerably more criminally active and diverse than the other crime groups. Prior criminal record, irrespective of type, increased the risk of recidivism in general. Controlling for other background characteristics did not alter this outcome. Treatment of convicted rapists needs to take into consideration that this offender group has much in common with violent offenders in general.     

Differentiating sexual violence: A comparison of sexual homicide and rape

Abstract

The present study sought to identify consistent patterns in the actions of sexually violent offenders to determine whether sexual homicide and rape reflect different behavioral emphasis of a single thematic model of sexual assault. Crime scene behaviors of 74 (37 sexual homicides and 37 rapes) solved cases of sexual assaults were compared, and results of a multi-dimensional analysis revealed three thematic styles of interacting with the victim during a sexual assault (Exploit, Control, and Violent). Further analysis indicated that offender–victim interactions in sexual homicide and rape are predominantly distinguished by the degree of violence, such that behaviors associated with each type of offense were found to occur in two discrete areas along a single continuum. Findings are discussed in terms of producing a general framework for understanding sexual violent interactions.     

Components underlying sex offender treatment refusal: an exploratory analysis of the Treatment Refusal Scale—Sex Offender version

Abstract

Approximately half of sexual offenders in prison and community settings refuse to participate in sex offender treatment programmes; however, the reasons for this remain largely unexplored. This pilot study used the previously untested Treatment Refusal Scale—Sexual Offender Version in an English prison, with 72 adult males (63 treatment accepters and nine treatment refusers) imprisoned for sexual or sexually motivated offences. Principal factors analysis revealed three factors within the scale: “pressured to take part in programmes”; “fear of negative effects”; and “programme is not relevant to/appropriate for me”. Treatment refusers scored more highly than treatment accepters on the first and last components, while there was no statistically significant difference in the scores of the two groups on the “fear of negative effects” component. Suggestions for further development of the scale are discussed, along with the practice implications of these findings.
