Predicting multiple victim versus single victim sexual abuse: an examination of distal factors and proximal factors associated with the first abuse incident

Abstract

Official and confidential self-report data on 83 convicted adult male sexual abusers were analysed to examine whether sexual offending progression can be better predicted from distal antecedents, or from proximal antecedents and outcomes associated with the first sexual abuse incident. Fifty-six offenders who sexually abused more than one victim (multiple victim offenders; MVOs) were compared to 27 offenders who sexually abused a single victim only (single victim offenders; SVOs). MVOs were younger at the time of their first sexual abuse incident, and were more likely to first abuse male and non-familial children. With the exception of sexual attraction to male children, no differences were found between the two groups on distal antecedents. Proximal antecedents and outcomes associated with the first sexual abuse incident were significantly related to multiple victim offending. Logistic regression analysis identified the presence of sexual difficulties in the month prior to the first abuse incident, and sexual excitement immediately preceding the first incident, as significant unique predictors. Implications for risk assessment and risk management are discussed, and future research directions proposed.     

Sentencing disparities for juvenile offenders sentenced to adult prisons: An individual and contextual analysis

While the punishment of juvenile offenders has increasingly become an issue of major concern to the public, there are few studies that test the government's coercive response to offending by this particular group. This study addresses this issue by examining the variation in sentence length for juvenile offenders adjudicated in the adult criminal courts for violent offenses. Results from the regression analyses consistently show that, while factors related to the specific offense are important contributors to the variation in sentence length, differences in the ideological climate of each state are a strong predictor of the variation in adult sanctions for minors. Specifically, the findings show that conservative citizen ideology and Republican control of state government are important contributors to the variation in sentencing of juveniles across U.S. states. Additional evidence shows that states where judges must run in an election to gain their seats proscribe more severe sanctions on juvenile offenders by sentencing more of them to adult prisons. Overall, the results suggest that the social and political climate of each state plays a very strong role in the sentencing of juvenile offenders to adult prisons.     

Predictive accuracy of static risk factors for Canadian Indigenous offenders compared to non-Indigenous offenders: implications for risk assessment scales

ABSTRACT

The over-representation of Indigenous offenders in Canadian prisons highlights the importance of research on the generalizability of potential static risk factors for this group. The current investigation examined whether 87 static indicators currently assessed in Canadian federal prisons were differentially present and related to outcomes (revocations, general recidivism, and violent recidivism) for Indigenous (n?=?1500) and non-Indigenous (n?=?6684) male federal offenders. The follow-up was eight months for revocations and five years for any/violent recidivism. Indigenous offenders scored significantly higher risk than non-Indigenous offenders on the majority of the indicators (particularly criminal history indicators). Generally, most criminal history indicators and some offence severity indicators predicted revocations, general, and violent recidivism for Indigenous offenders; however, several of the indicators had significantly lower accuracy for Indigenous offenders (particularly criminal history indicators). Overall, Indigenous offenders are a higher risk population and several static risk indicators do not perform as well for this group as for non-Indigenous offenders. Nonetheless, there were numerous static indicators that did predict outcomes for Indigenous offenders. The current findings suggest that it is possible to meaningfully assess static risk for recidivism among Indigenous offenders.     

Understanding the factors that affect the severity of juvenile stranger sex offenses: the effect of victim characteristics and number of suspects

Understanding factors that affect the severity of a juvenile-stranger sexual assault has implications for crime prevention, and potentially, the assessment and treatment of juvenile sex offenders. This study investigated how victim characteristics and the number of suspects affected the use of physical violence and weapons and the occurrence of penetration in 495 allegations of sexual assault committed by juveniles against strangers. Statistically significant interactions between victim age and gender were found for occurrence of penetration and use of violence. Differences in offense characteristics were also found between offenses with varying victim-suspect age differences. When comparing the rate of penetration in the presence and absence of violence, little change was observed for lone suspects. However, the rate of penetration increased significantly for groups in the presence of physical violence, suggesting that violence in this context may be more expressive than instrumental. Theoretical explanations and practical implications are considered.     

Individualization,criminalization, or problem resolution: A factorial survey of juvenile court judges' decisions to incarcerate youthful felony offenders

Existing research on the criteria used by juvenile court judges in choosing dispositions is limited in two respects. First, the predictor variables included in most investigations have been limited either in number or in the quality of their measurement. Second, research has not focused on sentencing decisions for serious offenders. Using a factorial survey of juvenile court judges, the present study seeks to determine what factors shape disposition decisions for juvenile felony offenders. The results suggest that judges focus primarily on offense characteristics, and are influenced only marginally by the offender's social characteristics. These findings are more consistent with the view that juvenile courts are becoming “criminalized” than with the view that individualized treatment is the goal. An alternative interpretation—that judges may be problem solvers, trying to dispose of cases efficiently—also is proposed.     

Training multi-disciplinary teams to work with sex offenders: Effects on staff attitudes

Abstract

A recent British Prison Service initiative has focused on providing sex offender programmes facilitated by multi-disciplinary teams of staff. A three week long training programme was designed to provide staff with the necessary knowledge, skills and experience to facilitate these structured treatment groups. Following the training, staff indicated they were more confident in their ability to provide treatment and showed a greater belief that treatment could be successful. In addition, they showed significantly more positive attitudes towards sexual offenders and to offenders in general. However, participants did not indicate undue concern about working in a sensitive treatment area. This pattern continued at six month follow-up, indicating that the training changed attitudes as expected, and that the training was seen by participants as adequately preparing them to undertake provision of a structured sex offender treatment programme in a secure setting.     

Applying the Consolidated Standards of Reporting Trials (CONSORT) to studies of mental health provision for juvenile offenders: a research note

The degree of reporting transparency in randomised controlled trials (RCTs) is an important factor when the validity of any results is being considered. The use of the Consolidated Standards of Reporting Trials (CONSORT) guidelines has improved the reporting standards of RCTs in many healthcare journals, but these guidelines have yet to be adopted universally. In this study, we applied the CONSORT Statement to RCTs identified from a systematic review of mental health provisions for juvenile offenders. We assessed the number of CONSORT items reported in each trial and investigated the extent of endorsement by journal editors. The findings showed that some items were fully endorsed (e.g., the aim of the study) whereas other items, such as sample size estimations, were not presented in any of the trials. A minority of journals supported the use of the CONSORT Statement in their journals’ instructions for authors. The overall reporting standard for this sample of trials was, therefore, mixed. Comparisons with trials conducted in other disciplines are discussed, and suggestions for improving reporting standards are presented.

The factors associated with criminal recidivism in Finnish male offenders: importance of neurocognitive deficits and substance dependence

Neurocognitive deficits and psychiatric disorders are often brought up as risk factors of recidivism. In this study, we investigated how neurocognitive and academic deficits and psychiatric disorders (including substance dependence) are associated with criminal recidivism and prison career among male offenders. In a health survey of Finnish prisoners, 72 sentenced male prisoners were examined in Turku prison using a neurocognitive test battery and psychiatric assessment including a standardized psychiatric interview (SCID-I, II). The neurocognitive and academic tests were chosen to assess domains of cognitive functioning and reading, spelling and mathematical skills. Our results showed that the combination of neurocognitive deficits and substance dependence was connected to recidivism. Axis I diagnosis (major mental disorders) and substance dependence were connected with neurocognitive and academic deficits. Moreover, first-time offenders had fewer neurocognitive deficits and Axis I disorders, less substance dependence and fewer personality disorders than those with several convictions. Rehabilitation of cognitive functions and academic skills, along with intervention for mental health problems and substance dependence could help to prevent the unfavourable circle of criminal career.     

Generating data with sexual offenders using qualitative material: A paradigm to complement not compete with quantitative methodology

This paper proposes triangulation as a research strategy in which the domain of sexual offending may be assessed using both qualitative and quantitative data. Examples of studies that have employed this approach with sexual offenders are outlined, showing the benefit that can be gained from utilizing multiple methods of assessment. The paper also outlines a range of quality criteria when conducting qualitative research, that Gaskell and Bauer (2000) argue are functional equivalents of reliability and validity.     

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.     

Developments in the assessment and treatment of sexual offenders: looking backward with a view to the future

This article provides a brief review of a number of key developments within the area of sexual offending over the past two decades. In addition, several directions for future research are discussed. The review presents information concerning several well-validated risk assessment instruments that are available. As well, some of the accumulating evidence concerning the efficacy of contemporary approaches to treatment with sex offenders is mentioned, as are theoretical developments within the field.     

Long-term psychological distress associated with marital rape and aggravated assault: A comparison to other crime victims

This study compared four groups of women who reported being the victims of a single violent crime (total N = 47) and a group of non-victimized women (N = 96). Victims were divided into groups based on the type of assault (rape vs. aggravated assault) and the identity of their assailant (husband vs. stranger). The groups were compared on measures of psychological functioning and symptoms of Post-Traumatic Stress Disorder. Crime victims reported higher levels of psychological distress than did the non-victimized women across a variety of symptom areas. There were no group differences among the four victim groups on any of the measures. Women assaulted by their husbands were more likely to report that the assault was one of a series of similar attacks. Victims of aggravated assault were more likely than rape victims to report that they feared for their lives during the assault. Results are discussed with respect to societal views on the comparative severity of marital and stranger assaults.     

Mentally ill offenders eligible for diversion at local court in New South Wales (NSW), Australia: factors associated with initially successful diversion

Diversion away from the criminal justice system and into mental health treatment services is a key strategy for addressing the well-established burden of mental illness suffered by those presenting to court. While mental health courts, court liaison and court diversion services have been developed in many jurisdictions internationally, there is limited research evidence to support their effectiveness in identifying those with mental health need and achieving successful diversion. The Statewide Community and Court Liaison Service in New South Wales, Australia, identifies mentally ill offenders likely to meet legal eligibility criteria for diversion at the busiest local courts across the state. Utilising data collected by mental health clinicians working in the service, 8317 individuals were identified as being eligible for court diversion on at least one occasion during the study period (1 July 2008 and the 30 June 2015) and 57.3% were subsequently diverted by Magistrates. Successful diversion at this first step was associated with being female, older, of non-Aboriginal and/or Torres Strait Islander background, and having a serious mental illness, replicated when stratified by sex and by Aboriginal and/or Torres Strait Islander background. There may be barriers to mental health diversion at court for individuals with particular socio-demographic characteristics which future service developments may need to take into account.     

Working with sex offenders in a climate of public blame and anxiety: How to make defensible decisions for risk

Abstract

Work with sex offenders takes place in a climate of public blame and anxiety. This requires practitioners to adopt the highest standards of practice to ensure that defensible decisions are made. These are decisions that must withstand hindsight scrutiny in the light of a risk management failure. This paper reviews the key practice points that will assist practitioners in making defensible decisions, and the key challenges for practitioners in this challenging area of work.     

Perpetrators of sexual assault continuing to have sex with their victims following the initial assault: evidence for evolved reproductive strategies

Among a sample of college students, roughly 30% of the women and 12% of the men reported having been the victim of a sexual assault sometime in their lives. Of the assault victims, approximately 23% of both sexes stated that they had sexual intercourse with their assaulters on at least one subsequent occasion. Female victims of a completed sexual assault were significantly more likely to continue being sexually active with their assailants than were female victims who managed to block the assault, while no such difference was found for male victims. This would imply that some men are using assaultive tactics to secure sex partners beyond a single sexual episode, thereby enhancing their potential reproductive success in evolutionary terms. Also, men who committed sexual assault reported having had more lifetime sex partners than did sexually experienced men with no sexual assault history. Overall, the idea that sexual assault is part of an evolved reproductive strategy is consistent with findings from this study.     

What to do with all these Bayes factors: How to make Bayesian reports in deception research more informative

Bayes factors quantify the evidence in support of the null (absence of an effect) or the alternative hypothesis (presence of an effect). Based on commonly used cut‐offs, Bayes factors between 1/3 and 3 are interpreted as evidentially weak, and one typically concludes there is an absence of evidence. In this commentary on Warmelink, Subramanian, Tkacheva, and McLatchie (Legal Criminol Psychol 24, 2019, 258), we discuss how a Bayesian report can be made more informative. Firstly, this implies a departure from the labels provided by commonly used cut‐offs when reporting Bayes factors. Instead, we encourage researchers to report the value of the Bayes factors, or to convert these values into nominal support for the hypotheses. Secondly, researchers can provide recommendations to design follow‐up studies by examining the posterior distribution of the magnitude of the effect size. Lastly, we show how individual Bayes factors can be evaluated in the context of large‐scale meta‐analyses.
