The Impact of a Public Health Campaign to Deter Viewing of Child Sexual Abuse Images Online: A Case Study of the UK Stop It Now! Campaign.

Public campaigns offer an opportunity to prevent child sexual abuse by raising awareness and promoting help available to bystanders, victims, and those at risk of perpetrating the abuse. This paper explores the impact of The Lucy Faithfull Foundation's 'Stop It Now!' campaign in the UK (2015-2018) on help-seeking. Helpline calls (11,190 unique callers), website analytics (109,432 new website visitors) and three website-hosted surveys (N = 252) provided data on help-seeking, awareness, and self-reported behavior. Results indicated that there were more visitors to the help website during active campaigning periods, and helpline callers and website visitors were more likely to seek help after viewing campaign materials during active than non-active campaign periods. Help-seekers were predominantly men concerned about their own behavior. Survey 2 respondents concerned about their own behavior (n = 53) indicated that their awareness of the law (75.5%), and legal and personal consequences (67.9%) had changed after hearing about the campaign, and 66% reported a change in behavior. Public health campaigns may be an effective way to promote help-seeking and prevent abuse.

Noncompleted Sexual Offenses: Internal States, Risks and Difficulties Related to Crime Commission through the Lens of Sexual Offenders.

The study aims to generate insights from sexual offenders on the influence of internal states and how they perceive risks of apprehension and difficulties in the context of noncompleted sexual offenses, that is when offenders initiated the offense but were stopped or discouraged either before or during sexual contact. Adult males incarcerated for sexually offending completed a self-report questionnaire. Regression models, including interaction effects, were estimated. Two interaction effects were found providing insights into which and how internal states, such as intoxication to alcohol, may influence perceived difficulties related to crime. Future research should promote the investigation of noncompleted sexual offenses, which could provide a real opportunity to generate new or complementary insights for better understanding and guiding prevention initiatives.

Effects of Automated Messages on Internet Users Attempting to Access "Barely Legal" Pornography.

With the increasing number of individuals accessing online child sexual exploitation material (CSEM), there is an urgent need for primary prevention strategies to supplement the traditional focus on arrest and prosecution. We examined whether online warning messages would dissuade individuals from visiting a honeypot website purporting to contain barely legal pornography. Participants (n = 419) seeking the site were randomly assigned to one of five conditions; they went straight to the landing page (control; n = 100) or encountered a warning message advising of the potential harm to viewers (n = 74), potential harm to victims (n = 65), ability of police to track IP addresses (n = 81), or possible illegality of such pornography (n = 99). We measured the attempted click-through to the site. Attrition rates for the warning message conditions were 38% to 52%, compared with 27% for the control group. The most effective messages were those that warned that IP addresses can be traced (odds ratio [OR] = 2.64) and that the pornography may be illegal (OR = 2.99). We argue that warning messages offer a valuable and cost-effective strategy that can be scaled up to help reduce the accessing of CSEM online.

Situational Crime Prevention in Sexual Offenses Against Women: Offenders Tell Us What Works and What Doesn't.

This study examined the perceived effectiveness of situational crime prevention (SCP) in sexual assault as rated by 140 offenders convicted for sex offenses against women in Australia. Participants were presented with three scenarios and asked to rate the perceived effectiveness of SCP techniques relating to guardianship, victim self-protective behavior, and crime prevention through environmental design (CPTED). Results indicate that the effectiveness of SCP methods was perceived to vary across different contexts. For offenses occurring in the private setting of an offender's home, victim self-protective behavior was seen as most effective, followed by guardianship and CPTED. In public settings, although the perceived effectiveness of victim self-protective behavior remained the same, guardianship and CPTED were rated as significantly more effective. Further variations were identified regarding specific strategies. Findings highlight the nuances of offender decision making in different situations and environments, and provide the first empirical comparisons of SCP perceptions among sex offenders.

Alcohol and drug problems among Australian homicide offenders.

BACKGROUND AND AIMS: Most homicide studies focus upon 'acute' situational intoxication as opposed to 'chronic' substance misuse. The aims of the study were to: (1) determine the extent of homicide offenders' alcohol and drug use in the year preceding the homicide; (2) compare the individual characteristics of homicide offenders across levels of problematic substance use; and (3) compare homicide incident characteristics across levels of problematic substance use. DESIGN AND SETTING: Observational study using data collected through face-to-face interviews in custodial and community correctional settings across Australia. Participants were recruited through an opt-in process. PARTICIPANTS: The data consist of 302 individuals convicted of murder or manslaughter. MEASUREMENTS: We used the Alcohol Use Disorder Identification Test and Drug Abuse Screening Test to determine problematic alcohol or drug use. We also used a range of self-report measures to ascertain offender characteristics [socio-demographics, developmental experiences, criminal history, personality] and incident characteristics (who was killed, and situational intoxication). FINDINGS: Of the sample, 38.8% displayed high levels of alcohol problems and 30.8% displayed high levels of drug problems. Those displaying high levels of alcohol and/or drug problems were more likely than those without high levels of alcohol and/or drug problems to report adverse developmental experiences, low education, financial difficulties, extensive criminal histories and high levels of trait anger, impulsivity and risk-seeking. In addition, offenders with problematic substance use were more likely to have killed non-family and to have used substances at the time of the homicide. CONCLUSIONS: High proportions of homicide offenders in Australia appear to have problematic substance use in the year preceding the homicide offence, and such use appears to be associated with a range of other challenging factors, including adverse childhoods, criminal involvement, low socio-economic factors and low self-regulation.

Criminal Careers Among Female Perpetrators of Family and Nonfamily Homicide in Australia.

Knowledge of women's pathways to serious offending, including homicide, is limited. This study contributes to a small but growing body of literature examining the criminal careers of serious female offenders by using interview data with females convicted of murder or manslaughter in Australia to examine various dimensions of their criminal careers, specifically, prevalence, frequency, age of onset, duration, and offending variety. In particular, in this study we compared criminal career dimensions across women who had killed a family member (e.g., intimate partner, children) and those whose victims were not part of the family unit (i.e., acquaintances or strangers). Our findings reveal differences between female homicide offenders who kill within and outside of the family unit. Although both groups had comparable overall lifetime prevalence of self-reported participation in criminal offending, findings indicate that participation among the family group was typically at low levels of frequency, of limited duration, and with relatively little variety in categories of offending. The family group also reported lower contact with the criminal justice system compared with the nonfamily group, and were less likely to have experienced some form of criminal/legal sanction in the 12 months prior to the homicide incident. This suggests that women who kill family members are more "conventional" than their nonfamily counterparts, in terms of having low and time-limited (i.e., short duration) lifetime participation in criminal offending.

What Deters Child Sex Offenders? A Comparison Between Completed and Noncompleted Offenses.

This study examined the role of the reaction of the victim, the nature of the physical setting, and the proximity of third parties in deterring offenders from completing an act of child sexual abuse (CSA). A self-report study was conducted with 238 adult males serving a custodial sentence for CSA, of whom 82 identified an occasion in which they had tried to have sexual contact with a child but did not because they were stopped or discouraged. We examined the situational characteristics of the noncompleted offense and compared these with the most recent completed offense by the same offenders. The most common reason for stopping the noncompleted offense, given by more than half of the participants, was the negative reaction of the child, and in particular, the direct request by the child to stop. Actual or potential actions by third parties were the next most cited reasons, with around a quarter of cases stopped because the offender was interrupted. In comparison to the noncomplete offense, in the completed offense the child was more likely to be younger and to be perceived as a willing participant. The most common suggestion for what might have stopped the completed offense, endorsed almost universally, was a negative reaction from the child. Factors that increased the chance of being detected-someone being nearby and the possibility of being observed-were also strongly endorsed. We argue that the findings provide the basis for devising offense-focused prevention strategies for CSA.

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.

Towards a 'smart' cost-benefit tool: using machine learning to predict the costs of criminal justice policy interventions.

BACKGROUND: The Manning Cost-Benefit Tool (MCBT) was developed to assist criminal justice policymakers, policing organisations and crime prevention practitioners to assess the benefits of different interventions for reducing crime and to select those strategies that represent the greatest economic return on investment. DISCUSSION: A challenge with the MCBT and other cost-benefit tools is that users need to input, manually, a considerable amount of point-in-time data, a process that is time consuming, relies on subjective expert opinion, and introduces the potential for data-input error. In this paper, we present and discuss a conceptual model for a 'smart' MCBT that utilises machine learning techniques. SUMMARY: We argue that the Smart MCBT outlined in this paper will overcome the shortcomings of existing cost-benefit tools. It does this by reintegrating individual cost-benefit analysis (CBA) projects using a database system that securely stores and de-identifies project data, and redeploys it using a range of machine learning and data science techniques. In addition, the question of what works is respecified by the Smart MCBT tool as a data science pipeline, which serves to enhance CBA and reconfigure the policy making process in the paradigm of open data and data analytics.

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.

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.

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 Snow's 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.

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.

Victim resistance in child sexual abuse: a look into the efficacy of self-protection strategies based on the offender's experience.

This study examines the efficacy, as experienced by offenders with their victim, of self-protection strategies used in child sexual abuse cases. It also investigates whether the efficacy of self-protection varies according to victim characteristics. The sample consists of 94 adult offenders who sexually abused a single child and who agreed to provide confidential self-report data on the efficacy of self-protection strategies used by their victim. Strategies taken into account are: (1) yelling or screaming, (2) fighting back, (3) saying no, (4) saying they didn't want to, (5) crying, (6) telling someone else about the abuse, (7) saying they were scared, (8) demanding to be left alone, (9) saying they would tell someone, (10) saying that people are not supposed to touch their private parts, (11) trying to get away, and (12) yelling for help. Saying that they do not want to have sexual contact and saying "no" to the offender are the most effective strategies. Because they are more likely to use self-protection initially, younger girls are also more likely to prevent episodes of abuse than older girls.

An exploratory study of victim resistance in child sexual abuse: offender modus operandi and victim characteristics.

The use of self-protection strategies and related situation in rape has been studied by several scholars. The circumstances in which children are more likely to resist sexual victimization have, however, not been studied. This study examines the association between offence-related factors-specifically, the preoffence situation, the modus operandi strategies adopted by offenders, and victim characteristics-and victim resistance in sexual offences against children.The sample consisted of 94 adult offenders convicted of having committed a sexual offence against a child (or adolescent) of 16 years of age or younger and who agreed to provide confidential self-report data concerning their offending behavior and victim resistance actions. Victim resistance strategies were regrouped into three categories, namely, physical resistance, forceful verbal resistance, and nonforceful verbal resistance. The total number of resistance strategies was also used in the analyses. Overall, the age of the victim was found to be related to nonforceful verbal resistance, and violence was related to all forms of resistance.Younger girls were found to be more likely to employ nonforceful verbal resistance than older girls and to use a greater number of strategies as well. To provide reliable knowledge to build on for reducing the risk of child sexual abuse, this study suggests the need for prevention programs to include empirical findings regarding the circumstances in which children are more likely to resist sexual victimization.

Onset, persistence, and versatility of offending among adult males convicted of sexual offenses against children.

Official sexual and nonsexual offense histories and confidential self-report data on sexual offending were obtained on 207 adult males serving sentences for sexual offenses against children (98 intrafamilial, 72 extrafamilial, and 37 mixed-type offenders). The mean self-reported age when offenders first had sexual contact with a child was 32.2 years (median = 31 years; range = 10-63 years). The mean age at first conviction for any offense was 30.5 years (median = 27 years, range = 12-66 years), and the mean age at first conviction for a sexual offense was 37.3 years (median = 37 years; range = 15-76 years). Sixty-nine percent (n = 143) of the combined sample had at least one previous conviction, and 80% of these (n = 114) had first been convicted for a nonsexual offense. ANCOVA revealed a systematic pattern of onset with first convictions for any offense preceding first sexual contact with a child. Taken together, results indicate that, in general, adult child molesters (a) begin sexual offending in their 30s, (b) have already become involved in nonsexual crime by the time they first have sexual contact with a child, (c) are criminally versatile, and (d) vary considerably in their persistence with respect to both sexual and nonsexual offending.

Criminal diversity and paraphilic interests among adult males convicted of sexual offenses against children.

Official demographic and offense history data (n = 362) and confidential self-report data on paraphilic interests and behavior (n = 221) obtained on adult males convicted of sexual offenses against children were analyzed. Considerable criminal diversity was observed, with all standard categories of offenses represented in offenders' criminal histories. Most (86%) of the offenders' previous convictions were for nonsexual offenses, and most (92%) of the recidivist offenders had previously been convicted of at least one nonsexual offense. The prevalence of diagnosable paraphilias was low, with only 5% meeting formal diagnostic criteria for multiple (two or more) paraphilias other than pedophilia. Sexual offenders' paraphilic interests were unrelated to the extent of their sexual offense convictions but were significantly related to the extent of their nonsexual offense convictions. The results are better explained by a general theory of crime than by traditional clinical conceptions linking sexual offenses specifically with sexual psychopathology.
