Examining the relationship between sexual offenders and their victims: Interpersonal differences between stranger and non-stranger sexual offences

Abstract

The present study examined the behavioural differences in sexual assault offences in relation to the offender–victim relationship (stranger versus non-stranger). These differences were examined specifically in the context of four interpersonal themes of interaction: dominance, submission, hostility and cooperation. The details of 100 sexual offence cases (50 stranger and 50 non-stranger) were content-analysed, generating 58 dichotomous variables, covering offender and victim behaviour during the offence. χ² tests comparing the two samples found that offenders who were strangers to their victims were more likely than non-stranger offenders to display behaviours that indicate a hostile, violent offence style. In contrast, those offenders who knew their victims were more likely than strangers to display a less violent and more personal, compliance-gaining offence style. These findings are discussed in terms of their implications for offender rehabilitation and victim support.     

Sexual Assault within Intimate Partner Violence: Impact on Helpseeking in a National Sample

Within intimate partner violence (IPV), sexual assault is often subsumed under the heading of physical abuse, but evidence suggests qualitative differences in outcomes when both types of abuse occur. This study explores the cumulative effect of sexual assault and physical abuse by a current or former intimate partner on helpseeking. Using a dataset of 1,072 IPV victims from 8 states, we found that women who had experienced sexual assault in addition to physical abuse (44%) used more help, but were also more likely to say that they did not seek help when they needed it. Among those who were aware of services, fear was the greatest obstacle to reaching out for help. Implications include the need for information on best practices in addressing the sequelae of both physical and sexual assault in victim service agencies.     

Developing a University-Wide Institutional Response to Sexual Assault and Relationship Violence

SUMMARY

Students may be predisposed to benefit from mandatory service-learning programs based on their gender and upon whether their parents serve as models of helping. The role of each of these variables was examined in a survey of seventh grade students (n = 86) who were required to complete service during the school year. Results demonstrated that girls felt more positively about the specific program and were more likely to intend to help in the future than boys. Students with parental helping models were also more likely to intend to help in the future. Girls with parental models were more likely to have altruistic self-images than girls without parental models whereas the presence of parental helping models had no effect on boys' altruistic self-image. These results are discussed with regard to socialization of prosocial behavior in both boys and girls.     

Novel recovery methods for biological materials in cases of alleged sexual assault: A word of caution

Many believe that an increase in the public confidence in the investigation of sexual crimes, and in conviction rates, will lead to an increase in the reporting of these crimes. Consequently, Forensic Science Providers are continually striving to make improvements in evidence recovery and examination and the subsequent interpretation of evidence. One development is in methods that enable an individual to self-sample. However, in cases where a complainant has self-sampled, questions of when the samples were taken, how they were stored and so on, can be legitimately raised. Additionally the continuity and integrity of evidential samples may be questioned resulting in them not being acceptable to the courts and potential evidence could therefore be lost. There is a large emotional and psychological impact of sexual assault and rape and no complainant who reports a sexual assault and recovers material should have that evidence inadmissible to a court. Specialised units for victims of alleged sexual violence are available and offer far more than the recovery of evidential samples. This commentary on behalf of the Faculty of Forensic & Legal Medicine (FFLM) and the Association of Forensic Science Providers Body Fluid Forum (AFSP BFF) highlights the need for after care for the victims of sexual assault and why all evidence recovered in cases of alleged sexual assault and sexual violence should be obtained in line with best practice protocols.     

Comparative analysis of gamma-hydroxybutyrate and gamma-hydroxyvalerate using GC/MS and HPLC

This paper describes two analytical techniques used to separate and quantify gamma-hydroxybutyrate (GHB) and gamma-hydroxyvalerate (GHV). The first technique was a N,O-bis(trimethylsilyl)triflouro-acetimide-trimethylchlorosilane derivatization, followed by gas chromatography/mass spectrometry analysis using an HP-5 capillary column at a rate of 1.0 mL/min with a run time of 9.25 min. This technique was found to be sensitive (LOD 1 pg on column) and gave a low average error (5%) in a beverage study. When supplemented by a surrogate spike, the method yielded 97% analyte recovery from beverages. The second technique was high-performance liquid chromatography/UV (HPLC/UV) using a C-18 column with a (20:80% v/v) methanol:dibasic phosphoric buffer (10 mM, pH 3) at a rate of 1.00 mL/min with a run time of 7.5 min. UV detection occurred at 254 nm. This method was found to be less sensitive (LOD 0.05 microg on column) for direct analysis of aqueous samples. To remove interferences seen in the beverage study, a liquid-liquid extraction before HPLC analysis was tested. However, a decreased sensitivity (LOD 100 microg on column) and irreproducible peak profiles resulted.     

The Impact of Negative Forensic Evidence on Mock Jurors’ Perceptions of a Trial of Drug-Facilitated Sexual Assault

Legal concerns with regard to the adverse impact of a negative toxicological screening for date-rape drugs in a case of drug-facilitated sexual assault (DFSA) were the focus of a recent Canadian case (R. v. Alouache, 2003). To assess the impact of a negative forensic report, as well as the impact of expert testimony explaining the many factors that may contribute to a negative outcome, participants (N=171) received a written trial stimulus in which the forensic evidence (negative report, negative report plus expert testimony, no negative report and no expert testimony control) and the complainant's beverage consumption (alcohol, cola) were systematically varied. Results indicate that a negative finding in the absence of expert testimony produced greater verdict leniency and more favourable evaluations of the defendant's case. In contrast, no differences were found between the case in which the expert testified and a case in which the negative report and expert testimony were omitted.

Legal aspects of sexual violence—Does forensic evidence make a difference?

A survey was done of 307 alleged victims of sexual violence reported to the police departments in Greater Aarhus, Denmark, in 1999–2004. The legal disposition was ascertained and related to victim and assault characteristics together with the forensic medical and laboratory findings. The police pressed charges in more than half of the cases and 11% turned out to be false allegations. Nineteen percent of all cases ended with sentencing of the defendant. Sperm was detected in 35% of the examined and analysed cases, and in 46% consumption of alcohol prior to the assault was reported. Information in the forensic report regarding injury documentation, intoxication, and detection of sperm and DNA match between victim and alleged assailant did not aid in the prosecution of the case. Severe coercion used by the assailant increased the likelihood of conviction. Intoxication estimation and sperm detection suffered from low sensitivity compared with laboratory analyses. Results suggest the need for new research and optimising the sexual assault examination protocol to strengthen the legal impact of forensic evidence.

Effects of Trait Anger and Negative Attitudes Towards Women on Physical Assault in Dating Relationships

The present study investigated the combined effect of trait anger and negative attitudes towards women (i.e., hostility towards women, calloused sexual beliefs) on frequency of physical aggression in premarital relationships. A total of 263 college-aged men who reported that they were either currently involved in a romantic relationship or had been involved in at least one romantic relationship during the past 12 months were recruited. Participants completed a battery of questionnaires, including the Conflict Tactics Scale-2, Trait Anger Scale, Hostility Towards Women Scale, and Hypermasculinity Inventory. Correlational analyses indicated that trait anger, hostility towards women, and calloused sexual beliefs were positively associated with frequency of physical assault. Further, hierarchical regression analyses indicated that both hostility towards women and calloused sexual beliefs moderated the relationship between trait anger and frequency of physical assault, such that in men who possess more negative attitudes towards women, higher levels of trait anger lead to increased physical assault. Results provide initial support for the role of trait anger in dating violence and suggest the existence of a subgroup among premaritally violent males who possess negative attitudes toward women and also possess a strong tendency to experience intense levels of anger.
