Offenders' Attachment and Sexual Abuse Onset: A Test of Theoretical Propositions

Confidential self-report data obtained on 107 adult male child sexual abusers were analyzed to test theoretical propositions concerning the role of attachment problems in the onset of sexual offending. Offenders’ parent–child attachment relationships were most frequently characterized by affectionless control, reflecting low parental care and high overprotection and control. Offenders reported significantly less secure attachment with their fathers than with their mothers. Overall, weak continuity from childhood attachment to trait (general) adult attachment was found, with insecure attachment more stable than secure attachment. Childhood attachment problems, particularly with fathers, were more clearly reflected in state adult attachment (i.e., in the month preceding sexual offending onset) than in trait adult attachment. Offenders who were in an adult intimate relationship prior to their onset sexual offense reported significant state increases in attachment avoidance, and their onset offenses were more likely to involve a female familial victim. Offenders who were not in a relationship prior to offending onset were younger, and their onset sexual offenses occurred in much more diverse circumstances. These findings provide tentative evidence that directly and indirectly implicates offenders’ attachment problems specifically in the onset of their sexual abuse behavior. Implications for developmental prevention and early intervention, situational prevention, and offender treatment are discussed.

Predictors of victim disclosure in child sexual abuse: additional evidence from a sample of incarcerated adult sex offenders

The under-reporting of child sexual abuse by victims is a serious problem that may prolong the suffering of victims and leave perpetrators free to continue offending. Yet empirical evidence indicates that victim disclosure rates are low. In this study, we perform regression analysis with a sample of 369 adult child sexual offenders to examine potential predictors of victim disclosure. Specifically, we extend the range of previously examined potential predictors of victim disclosure and investigate interaction effects in order to better capture under which circumstances victim disclosure is more likely. The current study differs from previous studies in that it examines the impact of victim and offense variables on victim disclosure from the perspective of the offender. In line with previous studies, we found that disclosure increased with the age of the victim and if penetration had occurred. In addition, we found that disclosure increased when the victim came from a non-dysfunctional family and resisted the abuse. The presence of an interaction effect highlighted the impact of the situation on victim disclosure. This effect indicated that as victims get older, they are more likely to disclose the abuse when they are not living with the offender at the time of abuse, but less likely to do so when they are living with the offender at the time of abuse. These findings are discussed in relation to previous studies and the need to facilitate victim disclosure.

Prevention nearby: The influence of the presence of a potential guardian on the severity of child sexual abuse

The main aim of this study was to examine the effect of a potential guardian on the severity of child sexual abuse. Using data obtained on crime events from adult child sexual offenders incarcerated in Queensland (Australia), mixed-effects logistic regression analyses were conducted to examine the effect of potential guardianship on the severity of abuse. Controlling for victim and situational characteristics, the analyses showed that the presence of a potential guardian reduced the duration of sexual contact and the occurrence of penetration. Presence of a potential guardian decreased the risk of sexual penetration by 86%. The study highlights the importance of the presence of a potential guardian for reducing the severity of child sexual abuse, and suggests more broadly that guardianship may be an important protective factor in sexual offending.

John Snow's legacy: epidemiology without borders

This Review provides abstracts from a meeting held at the London School of Hygiene and Tropical Medicine, on April 11-12, 2013, to celebrate the legacy of John Snow. They describe conventional and unconventional applications of epidemiological methods to problems ranging from diarrhoeal disease, mental health, cancer, and accident care, to education, poverty, financial networks, crime, and violence. Common themes appear throughout, including recognition of the importance of Snows example, the philosophical and practical implications of assessment of causality, and an emphasis on the evaluation of preventive, ameliorative, and curative interventions, in a wide variety of medical and societal examples. Almost all self-described epidemiologists nowadays work within the health arena, and this is the focus of most of the societies, journals, and courses that carry the name epidemiology. The range of applications evident in these contributions might encourage some of these institutions to consider broadening their remits. In so doing, they may contribute more directly to, and learn from, non-health-related areas that use the language and methods of epidemiology to address many important problems now facing the world.

A Criminal Careers Typology of Child Sexual Abusers

We present a criminal careers typology of child sexual abusers constructed in terms of their offending persistence (persistent vs. limited) and versatility (specialized vs. versatile). Analyses were conducted on the official records of 362 convicted offenders, 213 of whom also provided confidential self-report data on their personal and offending histories. Forty-one percent of the sample were currently serving sentences for their first sexual offense conviction(s) but had at least one prior conviction for a nonsexual offense (limited/versatile); 36.4% had no previous convictions of any kind (limited/specialized); 17.8% had prior convictions for sexual and nonsexual offenses (persistent/versatile); and 4.8% had prior convictions for sexual offenses only (persistent/specialized). These four groups differed on a range of personal and offense-related variables, including abuse histories, sexual orientation, age at first sexual contact with a child, number of victims, duration of sexual involvement with victims, victim gender, and whether victims were familial or nonfamilial. These differences suggest the need to adopt different treatment and prevention strategies that target the specific characteristics of each group.

Police officers’ perceptions of the challenges involved in Internet Child Exploitation investigation

Purpose – The purpose of this paper is to explore police officers’ perceptions of the challenges and work stressors of working in Internet Child Exploitation (ICE) investigation. Design/methodology/approach – Participants were a heterogeneous sample of 32 ICE investigators across nine Australian jurisdictions. Officers’ perceptions of ICE work were elicited via individual, open-ended, anonymous, telephone interviews, which focused on both the nature and impact of work-related stressors and challenges. Findings – Thematic analysis revealed that viewing ICE material was not perceived to be a major stressor or particularly traumatic facet of ICE investigation. Rather, the challenges related to three areas; work relationships, workload and resources and the physical environment. Participants also suggested some improvements to their work environment which could reduce the impact of these challenges. Practical implications – The stressors identified by ICE investigators in this study place physical, psychologi...

Characteristics of Homicide-Suicide in Australia A Comparison With Homicide-Only and Suicide-Only Cases

Homicide-suicide represents one of the rarest forms of lethal violence but often precipitates calls to revise social, health, and justice policies. However, there is little empirical information about this type of violence. The current study uses two unique data sets to examine a wide range of individual and situational characteristics of homicide-suicide, with particular emphasis on establishing whether and how homicide-suicide differs from homicide-only and suicide-only. Findings suggest homicide-suicide may have unique characteristics that set it apart from both homicide-only and suicide-only, as well as sharing certain other characteristics with those two types of events.

Intimate Femicide: The Role of Coercive Control:

Severe and escalating violence is cited as a precursor to intimate partner homicide and figures prominently in risk assessments and domestic violence death reviews. Drawing on interviews from the Australian Homicide Project with a sample of men convicted of killing intimate partners, we examine the backgrounds of perpetrators and the contexts in which the killings occurred and find that fully half report no physical or sexual assaults against their partners in the year prior to the homicide. These results raise important questions about assessments of risk and the typification of the “battered woman” on which many policy responses rely.

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.

Situational precipitators and interactive forces in sexual crime events involving adult offenders

We investigated the role of situational precipitators in sexual offenses in relation to the use of physical force by offenders, penetration of the victim, and physical injuries to the victim. We used self-report data obtained from a Canadian sample of 553 incarcerated adult male sexual offenders. All data used in this study were gathered through a semi-structured interview conducted with each participant. First, we found that 75.8% of sexual crime events were somehow precipitated, or characterized, by the presence of precipitators before crime. Second, the relationship between each precipitator and the type of offense was statistically significant except for one precipitator. Third, although a number of precipitators were associated with the dependent variables, we also found two interaction effects that illuminated the complexity of the role of precipitators in sexual offenses. Interaction analysis can increase our understanding of sexual crime events and better inform prevention practices, such as relapse prevention.
