Abstract Crime scene profiling has received considerable attention, particularly in popular media. First, since low inter-rater reliability would affect the validity of profiling, we tested inter-rater agreement for 33 variables often used in manuals for the coding of crime-related behaviour. Thirty cases were chosen randomly from 146 cases of assault rape with unknown male offenders in Sweden during 1990–1994. Second, we used multidimensional scaling (MDS) with all 146 cases to replicate earlier work by Canter and Heritage (Journal of Forensic Psychiatry, 1, 185–212, 1990) regarding motivational dimensions in unknown assault rapists. On average, inter-rater reliability was good; physical behaviours were more reliably coded than were verbal behaviours. However, a two-dimensional MDS solution with the motivational dimensions suggested by Canter and Heritage was not replicated. We argue for better empirical support for the inclusion of specific variables in coding formats for crime scene information. This is particularly important for analyses like the MDS, since the number, representativity, and intercorrelations of such variables could affect results considerably. 相似文献

Abstract Heterogeneity hinders our understanding of sexual violence; but does this problem extend to stranger rape and, if so, would the construction of homogeneous subtypes advance our understanding of this crime and aid criminal investigations and clinical practice? To answer these questions, 41 stranger rapists from the English high security hospitals were examined using version 3 of the Massachusetts Treatment Centre rapist typology (MTC:R3) and multidimensional scaling (MDS). The MTC:R3 suggested that sexual desire and opportunism were the primary motivations for these men, but that proportionately more psychopaths were violent and sadistic. In accordance with previous research, the men experienced problematic childhoods and displayed high rates of criminality and psychiatric morbidity in adulthood. However, MDS found that rapist histories and offence behaviours generally divide into sexual and violent themes. These results have important implications for theory, criminal investigations and clinical practice. 相似文献

Abstract Sturidsson et al. (Psychology, Crime & Law, 12, 221–230, 2006) published an article on the replicability of early multidimensional scaling (MDS) behavioural research by Canter and Heritage (Journal of Forensic Psychiatry, 1, 185–212, 1990). Sturidsson et al. were unable to find a ‘readily apparent, simple interpretation’ of their MDS solution and therefore suggested that the MDS approach may be flawed as a device for interpreting sexual assault. The current paper explains how the methods employed by Sturidsson et al. represent an incorrect use of MDS, specifically in their input of Jaccard similarity data into the MDS (ALSCAL) procedure in SPSS as opposed to the correct MDS (PROXSCAL) procedure. A comparative example is used to illustrate how adopting the ALSCAL procedure will result in an inverse MDS solution, where objects appearing closer together are more dissimilar, making interpretation of the MDS plot meaningless in this context. The current paper discusses this methodological flaw in greater depth and in the context of behavioural investigative research using MDS in general. It concludes with some general guidelines in utilizing the MDS procedure in SPSS specific to criminal profiling research. 相似文献

Abstract Examinations of treatment attrition form an important – although sometimes neglected – component of evaluating a correctional programme's effectiveness in reducing recidivism. Previous research has identified offender characteristics that predict non-completion. This study investigated non-completion in 138 high-risk, violent male prisoners attending an intensive cognitive–behavioural programme. Almost one-third of men who commenced it did not complete the 7-month programme. Most asked to leave of their own accord, or were removed for ongoing offending. In contrast to previous research, no support was found for the hypothesis that those who terminated treatment prematurely were more in need of intervention than those who completed the programme; non-completers did not differ from completers on static estimates of criminal risk, PCL-R scores, demographic variables or self-report scales measuring dynamic risk factors. It was concluded that successful prediction using variables related to criminal risk and criminogenic need depends both on the characteristics of programme participants, and on contextual factors such as programme policies: when high-risk high needs offenders are a programme's target clientele, variables related to risk and need will have limited predictive utility. From a practice perspective, the programme was successful in retaining through to completion a relatively untreatable group: high-risk offenders with moderate to high PCL-R scores. 相似文献

ABSTRACT Adverse childhood experiences have been associated with negative outcomes in adulthood, including sexual offending. Using a cross-sectional design, we investigated whether self-reported adverse childhood experiences related to the perpetration of coercive sexual acts among 250 females recruited from the community. Furthermore, we examined whether sexualised coping mediated any potential relationship between childhood experiences and sexual coercion. A Spearman’s rank order correlation revealed no relationship between adverse childhood experiences and sexual coercion. However, adverse childhood experiences were significantly correlated with sexualised coping, which in turn was correlated with sexual coercion. Additionally, there was a significant but small indirect effect of adverse childhood experiences on sexual coercion through sexualised coping. Findings may help researchers to better understand the causal relationship between childhood experiences, sexual coping, and sexual coercion in females. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

AbstractThe current study aimed to examine the transitioning experiences of adolescents with sexually harmful behaviour following treatment and to explore whether additional services are needed to facilitate their successful transition into the community. Qualitative methods were employed on data collected from in-depth interviews with 12 adolescents and 16 parent/caregivers. The age of adolescent participants at the time of interview ranged from 17 to 21 (average = 18.6 years). The results identified four key transitioning areas—accommodation, education/employment, social life and leisure, and emotional support. Several main overarching themes were also identified: reaching out for help is hard; adolescents need a focus and something to strive for; advice on financial management/budgeting would be useful; and adolescent motivation was important for successful transition. In addition, follow-up would be advantageous, as would mentors/role models during the transition period. The results are discussed in relation to current transitioning literature on similar at-risk populations, and recommendations are made to inform transitioning practice. 相似文献

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. 相似文献

Abstract Sexual homicide is a crime that receives much media attention, but one that still has a relatively small research base compared to other crimes. Although the idea of someone deriving sexual gratification from or during the killing of another is an anathema to many, forensic professionals need to understand sexual homicide and the range of circumstances and motivations that lie behind it. This paper explores this complex crime: it illustrates the various definitions and labels used; it suggests that sexual homicide is rare and is committed by individuals who, although having troubled histories, may not differ from other offenders. Then, by examining the various legal and behavioural circumstances in which sexual homicide can occur, this paper illustrates the diversity of sexual homicide and presents it in a more understandable manner. Finally, the paper suggests that knowledge of this diversity is required both for investigative and clinical purposes. 相似文献

Soil, being diverse and ubiquitous, can potentially link a suspect or victim to a crime scene. Recently scientists have examined the microbial makeup of soil for determining its origin, and differentiating soil samples is well-established. However, when soil is transferred to evidence its microbial makeup may change over time, leading to false exclusions. In this research, “known” soils from diverse habitats were stored under controlled conditions, while evidence soils were aged on mock evidence. Limited quantities of soil were also assayed. Bacterial profiles were produced using next-generation sequencing of the 16S rRNA gene. Overall, known soils stored open at room temperature were more similar to evidence soils over time than were known soils stored bagged and/or frozen. Evidence soils, even as little as 1 mg, associated with the correct habitat 99% of the time, accentuating the importance of considering ex situ microbial changes in soil for its successful use as forensic evidence. 相似文献

Soil has the potential to be valuable forensic evidence linking a person or item to a crime scene; however, there is no established soil individualization technique. In this study, the utility of soil bacterial profiling via next‐generation sequencing of the 16S rRNA gene was examined for associating soils with their place of origin. Soil samples were collected from ten diverse and nine similar habitats over time, and within three habitats at various horizontal and vertical distances. Bacterial profiles were analyzed using four methods: abundance charts and nonmetric multidimensional scaling provided simplification and visualization of the massive datasets, potentially aiding in expert testimony, while analysis of similarities and k‐nearest neighbor offered objective statistical comparisons. The vast majority of soil bacterial profiles (95.4%) were classified to their location of origin, highlighting the potential of bacterial profiling via next‐generation sequencing for the forensic analysis of soil samples. 相似文献

Abstract This paper argues that we should cease treating sexual offending as a problem best dealt with by psychology, medicine, or law. Sexual offending, like mental illness, alcoholism, or drug addiction, is a public health problem, one that is everyone's business. The paper first considers the traditional levels of prevention in public health: primary, secondary, and tertiary. The argument is made that most of our efforts have been directed to the tertiary level where they are least likely to be effective. Applications of the general public health model to sexual violence are considered. These include epidemiology, risk factor research, program evaluation, and dissemination of information on what works. Various methods for informing and educating the public about sexual violence are proposed. The paper concludes with suggestions on how harm can be minimised through the use of a public health approach. 相似文献

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. 相似文献

Abstract It is generally assumed that empathy acts to disinhibit behaviour that could be perceived as detrimental to others, and as a result is a common feature of offender treatment programmes. The present research hypothesised that empathy in all populations is both a situational and a selective process that is ultimately governed by self-interest, and further, that it is the nature of the self-interest that distinguishes individuals rather than a general empathy deficit per se. Empathic processes were observed in a non-offending population in a personal situation normally regarded as evocative of empathy: infidelity. Thematic analysis of data from individuals who reported being faithful or unfaithful to their partners revealed five dominant themes: vulnerable predisposition, emotional motivators, rational emotive decision making, avoiding cognitive dissonance and lack of remorse. The themes all revealed how individuals employed cognitive strategies, which were managed by self-interest that functioned to create cognitive states devoid of empathy. 相似文献

Abstract: Little is known about the racial patterns of crimes committed by sexual homicide offenders (SHOs). This study examined race and age influences on victim–offender relationship for juvenile and adult SHOs. A large sample (N = 3868) from the Supplemental Homicide Reports (1976–2005) was used. Analyses of victim–offender patterns included examining victim age effects (child, adolescent, adult, and elderly). The findings revealed several race‐ and age‐based differences. Black offenders were significantly overrepresented in the SHO population. This finding held for juveniles and adults independently. White SHOs were highly likely to kill within their race, “intra‐racially” (range 91–100%) across four victim age categories, whereas Black SHOs killed both intra‐racially (range 24–82%) and inter‐racially (18–76%), with the likelihood of their killing inter‐racially increasing as the age of the victim increased. This study underscores the importance of considering victim–offender racial patterns in sexual murder investigations, and it offers practical implications for offender profiling. 相似文献
