Adverse Childhood Experiences and Criminal Extremity: New Evidence for Sexual Homicide

Adverse childhood experiences are associated with a wide range of behavioral, health, and psychiatric deficits and have recently been used to study the development of serious offending careers. Unfortunately, this research paradigm has largely ignored forensic populations. This study utilized the adverse childhood experiences framework to examine the associations between exposure to violence, victimization, and total adverse childhood experiences on sexual homicide using a sample of 616 incarcerated adult male sexual offenders from Canada 85 of whom committed sexual homicide. Epidemiological tables of odds revealed that a gradient of adverse childhood experiences was associated with sexual homicide, but that the most significant risks were for offenders who had the most extensive abuse histories. In adjusted models, exposure to violence, victimization, and total adverse childhood experiences increased the odds of sexual homicide by 334%, 249%, and 546%, respectively. These effects intensified in models adjusted for childhood enuresis, cruelty to animals, parental abandonment, deviant sexual behaviors, poor self‐image, and sexual problems to 559%, 326%, and 849%, respectively. The adverse childhood experiences framework is a systematic way to organize the criminogenic developmental sequela in sexual homicide.     

Performance intelligence,sexual offending and psychopathy

Abstract

Previous studies have suggested that offenders have lowered verbal intelligence compared to their performance intelligence. This phenomenon has been linked traditionally to childhood risk factors (e.g. deficient education, abuse and neglect). Substantial discrepancies between performance intelligence quotients (PIQ) and verbal intelligence quotients (VIQ), however, might also point to neurobiological impairments which may be associated with specific types of criminal behaviour. From the files of 133 male hospitalized offenders, PIQ, VIQ, full scale IQ (FSIQ) scores and Psychopathy Checklist–Revised (PCL-R) scores were derived, along with information about their criminal histories. PIQ over VIQ discrepancies were most pronounced in sexual offenders, particularly in those who had committed sexual crimes against adult victims. Furthermore, PIQ as well as PIQ higher than VIQ discrepancies correlated modestly, but significantly, with PCL-R scores. The results suggest that lower verbal compared to visual and spatial abilities may be connected specifically to egocentric and narcissistic personality traits which, in turn, may be involved in raising the risk of sexual offending.     

Exploring the Relationship Between Childhood Sexual Abuse and Adult Sexual Perpetration

Empirical findings indicate that many adult sexual offenders experienced sexual abuse during childhood. It has been suggested that characteristics of offenders' sexual perpetrating behaviors may resemble their own victimization experiences, although there has been minimal empirical investigation in this area. The purpose of the present study was to provide preliminary data on the relationship between childhood sexual abuse and characteristics of sexual offending behavior. A sample of adult male sexual offenders with histories of sexual abuse completed the Sexual Victimization Survey as well as a measure on their sexual offenses. Such characteristics as the nature of sexual activities, duration and frequency of experiences, and age and relationship of participants were examined. Results showed trends in the hypothesized direction and revealed a variety of similarities between childhood sexual abuse and adult sexual perpetration. Findings of this exploratory study suggest the importance of addressing the nature of victimization in the treatment of sexually abused boys and offenders with histories of sexual abuse.     

Childhood attention deficit hyperactive disorder (ADHD) symptoms and adolescent female sexual victimisation: mediating and moderating effects of risky behaviours

Abstract

The mediating effects of risky behaviours on the linkage between childhood attention deficit hyperactive disorder (ADHD) symptoms and adolescent sexual victimisation in college women were examined using structural equation modelling (n=374). The moderating effects of timing onset of risky behaviours were also examined. General risky behaviour was not a significant mediator. Rather, findings supported a specificity hypothesis suggesting risky sexual behaviour is a better explanation of the ADHD symptoms–sexual victimisation association than is general risky behaviour. Early onset of alcohol or marijuana use, consensual sexual activity and staying out all night interacted with childhood ADHD symptoms to increase general risky behaviour and sexual risk-taking. We conclude that to understand the risk for sexual victimisation in adolescent females with childhood ADHD symptoms it would be advisable to focus specifically on sexual risk-taking.     

The association between childhood sexual abuse and sexual coercion in men: a test of possible mediators

ABSTRACT

We examined the associations between childhood sexual abuse (CSA), childhood physical abuse (CPA), sexual domain variables, antisocial tendencies, and sexually coercive behaviour in a non-forensic sample of 173 heterosexual men. CSA was associated with paraphilic interests and experiences, a more extensive sexual life history, and early antisocial tendencies. CPA was associated with paraphilic interests and experiences, more self-reported delinquency, higher sensation seeking, and early antisocial tendencies. Sexual domain variables (e.g. number of sexual partners, sexual interest in sadomasochism) mediated the link between CSA and sexually coercive behaviour, but antisocial domain variables (e.g. delinquency, sensation seeking) did not. Of the two sexual domains examined, extensive sexual life history rather than paraphilias mediated the association between CSA and sexually coercive behaviour. These results suggest CSA and CPA are associated with both sexual and antisocial outcomes, and that, for some victims of CSA, having an extensive sexual life history may account for the association between CSA and sexually coercive behaviour later in life.     

An analysis of the relationship between being deaf and sexual offending

Abstract

Research demonstrates that deaf offenders are over-represented within the criminal justice system. In addition, those deaf offenders who are incarcerated within prison estates or psychiatric units are predominantly incarcerated for sexual offences. This paper will evaluate the existing literature surrounding the reasons behind this bias. In particular, this review will examine the characteristics of deaf offenders in relation to their personalities, language and brain development and abilities to communicate. This paper will consider proposed associations between mental illness and childhood sexual abuse amongst deaf individuals and later sexual offending. This paper attempts to evidence differences between deaf and hearing offenders in order to explain why more deaf offenders commit sexual crimes than hearing offenders. This paper will conclude that the research is scarce and inconclusive and that current assessments and treatment are potentially inadequate due to the profound difficulties associated with accurately understanding and communicating with the deaf offender.     

Editorial

ABSTRACT

The current paper examined the association between childhood sexual victimization (CSV) and constructs thought to be relevant for sexual offending in secondary analyses of three samples of adult males who committed sexual offences against children (N?=?16, 28, and 20). Compared to participants who reported no CSV, those who reported CSV exhibited slightly to moderately more cognitive distortions and moderately to largely less negative evaluations of sexual offending against children; slightly to moderately higher self-esteem, positive evaluation of people who commit sexual offences, and identification with people who commit sexual offences against children; and much more emotional congruence with children. Our findings suggest that CSV may be associated with variables presumed to play a role in sexual offending against children. However, given the small sample sizes and other limitations of our studies, our evidence does not permit conclusions regarding causal relationships and any novel findings require replication.     

An overview of the literature on antecedents,perceptions and behavioural consequences of sexual harassment

Abstract

The detrimental effects of sexual harassment have been documented in the literature over the past 35 years, and recognized as a serious problem for all working women. In this paper, we review the existing research surrounding the phenomenon of sexual harassment, focusing upon the factors that may facilitate its occurrence. We also provide an overview of the differences in perceptions of what constitutes sexual harassment according to gender, organisational power and context. The negative impact of sexual harassment on its victims is also reviewed. Finally, the relatively new research on victims' responses to sexual harassment experiences and the link between this work and the stress and coping literature is recognized. Several suggestions are made for future research, policy making and treatment avenues.     

Victims of sexual assault perpetrated by female youth: an exploratory study of gender differences*

ABSTRACT

This study examines sexual offending behaviour of juvenile females and juvenile males who come to the attention of the police. Using victim age as an analytical tool and more than 20 years of incident-level crime data, perpetrator, victim, and offense characteristics are compared to assess if the offending behaviours of juvenile females and juvenile males differ when the victim is a child versus a peer. The multinomial logistic regression showed there were differences in offending between juvenile females and juvenile males dependent on type of victim. Perpetrator substance abuse, victim sex, victim-offender relationship, type of sexual assault, use of force, location of the sexual assault, the time of day of the sexual assault, and whether or not the incident resulted in an arrest all reliably predicted these differences. The results reinforce the field's call for a greater development of a gendered understanding of sexual offending behaviour.     

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.     

Toward a comprehensive theory of child sexual abuse: A theory knitting perspective

Abstract

In recent years a number of multifactorial theories of child sexual abuse have been developed. The most influential are Finkelhor's (1984) Precondition Model of child sexual abuse; Hall and Hirschman's (1992) Quadripartite Model; and Marshall and Barbaree's Integrated Theory (1990). While all three of these important theories have a number of strengths, each has serious weaknesses that limit its ability to provide a satisfactory explanation of child sexual abuse. In this paper we attempt to integrate the best elements of the three theories into a comprehensive etiological theory, or at least the beginnings of such a theory. After outlining the concept of theory knitting we briefly summarise each of the multifactorial theories and their major strengths and weaknesses. We then develop a comprehensive theoretical framework (the Pathways Model) integrating both the overlapping and unique elements of these broad perspectives with some additional concepts derived from various psychological domains. In the final section of the paper we consider the adequacy of the Pathways Model.     

Marshall and barbaree's integrated theory of child sexual abuse: A Critique

Abstract

The aim of the current article is to critically examine an extremely influential multi-factorial theory of child molestation, Marshall and Barbaree's (1990) integrated theory. This powerful model was developed as a general theory of sexual offending and used to explain the onset of child sexual abuse in addition to other forms of sexual deviance. Despite its prominent status the adequacy of its basic ideas have never been systematically evaluated. First, I describe the integrated theory in detail and outline its core assumptions. Next, these ideas are subject to critical analysis and I highlight its strengths and weaknesses. Finally, I conclude with some brief comments about the model and the role of theory development in the sexual offending area.     

Differential predictors of intimate partner sexual coercion versus physical assault perpetration

ABSTRACT

The current study attempted to strengthen existing literature regarding predictors of perpetrating intimate partner sexual violence to determine if there are unique predictors of sexual violence that differentiate it from physical abuse. It was hypothesised that men’s controlling, dominant and jealousy behaviours, and verbal aggression would significantly predict increased intimate partner sexual coercion and physical assault perpetration. These predictors were expected to be more predictive of sexual coercion than physical assault perpetration. Couples were recruited from the community (N?=?159) in a cross-sectional study recruiting couples with a violent male partner. Results demonstrated that men’s controlling behaviour was a significant predictor of sexual coercion and physical assault perpetration and behavioural jealousy was a significant predictor of sexual coercion perpetration. No predictors studied better predicted sexual coercion more than physical assault perpetration. These findings suggest that sexual coercion may be another type of physical assault without unique predictors.     

Female Sexual Homicide Offenders: A Descriptive and Comparative Study

Research on female sexual homicide has been very scarce. In Europe, it has rarely been examined, and in Scotland, it has never previously been studied. This exploratory study aims to examine the characteristics of sexual homicides involving female offenders between 1990 and 2015 in Scotland. Using data from the Scottish Homicide Database between 1990 and 2015, female sexual homicides (n = 7) were compared to nonsexual homicides committed by females (n = 106) and to sexual homicides committed by men (n = 89) using Fisher's exact tests. The findings show that although female sexual homicide offenders are similar to both female nonsexual homicide offenders and male sexual homicide offenders in certain aspects, there are important differences that distinguish sexual homicides involving female offenders from both groups. Female sexual homicide offenders can arguably be seen as a distinct group of offenders, with specific characteristics and specific needs.     

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.     

Beyond Traditional Definitions of Assault: Expanding Our Focus to Include Sexually Coercive Experiences

Traditionally, studies examining sexual assault have not considered experiences of coerced consensual sex. This study sought to compare women who endorsed experiences of coerced sexual intercourse with women who reported more traditionally defined experiences of sexual assault and with a group of women who had experienced neither sexual assault nor coercion. The authors hypothesized that women who had experienced sexual coercion would show symptom elevations on a measure of interpersonal trauma-related symptoms that were more consistent with sexual assault victims than with non-victims. Among a sample of undergraduate college women (N=300), women who endorsed coerced sexual intercourse (8.7%) were compared to women endorsing experiences meeting the legal definition of rape (21%), women endorsing childhood sexual abuse (11.7%), women reporting both rape and childhood sexual abuse (6.0%), and women reporting no victimization experiences (52.7%). Analysis of the Trauma Symptom Inventory (TSI; Briere, 1995) clinical subscales confirmed that women who reported coerced sexual intercourse endorsed symptoms levels more consistent with the adult rape group than with the non-victim group.     

Is sexually abusive behaviour in personality disordered inpatients analogous to sexual offences committed prior to hospitalization?

Abstract

Sexually abusive behaviour by personality disordered patients presents a serious threat to the integrity of staff–patient relationships and the safety of other residents. The occurrence of such behaviour is also problematic for the offending patient, as it may impact on perceived treatment needs and their access to the community. This paper reports on a study of sexually abusive behaviour in a high security psychiatric hospital. It also examines the relationship between these behaviours and patients’ history of sexual offending. The results showed a high frequency of low-severity sexually abusive behaviour and no significant associations between sexually abusive behaviour during hospitalization and sexual offence history. These findings imply that low-severity sexually abusive behaviour within secure settings may be determined, partly, by environmental conditions. This sexual abuse may also be functionally dissimilar to severe sexual abuse perpetrated in the community. The meaning and determinants of sexual abuse within secure settings must be scrutinized carefully and comprehensively before they are considered analogous to previous sexual offences.     

Sexual victimisation,sexual cognitions,desire and excitation/inhibition in community Spanish male and female sexual aggressors

Abstract

This study explored the relationship between some aspects of sexuality and individuals' likelihood to perpetrate sexual aggression in men and women. We assessed the following sexuality variables: content of positive sexual cognitions (PSCs)/negative sexual cognitions (i.e., intimate, exploratory, dominance/submission or impersonal), dyadic and solitary sexual desire, propensity for sexual excitation (SE)/sexual inhibition and sexual victimisation during childhood and/or adolescence/adulthood. We examined a community sample of 228 men and 333 women, of whom 67 men and 43 women had perpetrated sexual aggression. Compared to non-aggressors, male aggressors reported a higher frequency of PSCs of dominance; female aggressors reported a higher frequency of PSCs of dominance and exploratory and impersonal sexual cognitions as both positive and negative and negative impersonal cognitions. All sexual aggressors reported higher levels of solitary desire and propensity for SE. Regression analyses revealed that the most relevant variable in the prediction of sexual aggression was sexual victimisation during adolescence/adulthood in both sexes. Differences between male and female sexual aggressors are discussed.     

Childhood Sexual Abuse and Intimate Partner Violence among Women in Methadone Treatment: A Direct or Mediated Relationship?

Women in substance use treatment report rates of childhood sexual abuse and intimate partner violence that far exceed those reported by women in the general population. Previous research with nonrandom samples of women in substance use treatment suggests that there is a statistically significant relationship between childhood sexual abuse and intimate partner violence; however, little is known about the mechanisms of risk between these two public health concerns among this population of women. To address this gap in knowledge and to inform intervention strategies, this study examined direct and mediated relationships between childhood sexual abuse and intimate partner violence risk among a random sample of 416 women in methadone treatment. In addition to high rates of childhood sexual abuse (57.9%), intimate partner violence (lifetime prevalence, 89.7%; 6-month prevalence, 78.4%), posttraumatic stress disorder (PTSD, 28.6%), and global psychological distress (19.5%), findings suggest that the relationship between childhood sexual abuse and intimate partner violence is mediated by mental health problems and that women experiencing PTSD or global psychological distress are 2.7 and 2.4 times more likely to experience intimate partner violence than women without such experiences, respectively. Although not a mediator in this relationship, financial independence reduced women's risk of partner violence by two-thirds. The paper includes discussion of social learning and stress and coping theories to explicate the findings and to inform intervention strategies. This study is based, in part, on the first author's dissertation. A previous version of this paper was presented at the Society for Social Work and Research Annual Conference held in January 2005 in New Orleans, Louisiana.
