Expectancy violation and perceptions of rape victim credibility

Purpose. Rape victims have been found to have a heightened risk of secondary victimization in the legal system through biased perceptions of their credibility. In this study, participants observed a video of a rape victim reporting the crime and evaluated her credibility, to establish the influence of victim emotional expressiveness on evaluations of victim credibility. Methods. The nonverbal (eye‐contact, crying) and paralinguistic (tone of voice) behaviour of the rape victim was manipulated such that the emotional presentation viewed by observers was either expressive, or not expressive. One hundred and thirty seven participants were randomly allocated to observe a videotape of either an expressive or a non‐expressive victim. Participants’ specific expectations about the emotional expressiveness of rape victims in general were also measured. Results. Results revealed no significant main effect of emotional expressiveness on perceptions of credibility. However, among participants with a strong expectation of emotional expressiveness, a rape victim who was emotionally expressive was perceived to be significantly more credible than a victim who was not emotionally expressive. Conclusions. It appears to be expectancy violation rather than emotional expressiveness per se that biases observers’ perceptions of rape victim credibility.     

Interventions for Intimate Partner Violence: A Historical Review

Intimate partner violence (IPV), also known as domestic abuse or relationship violence, has generated a large research literature for the last half-century, particularly in the areas of criminal justice, psychology, and the social sciences. Interventions for victims and perpetrators of IPV have largely been sequestered to separately evolving efforts of law enforcement and the psychotherapeutic community (Chang et al. Women’s Health Issues, 15(1), 21–30, 2005; Dalton Journal of Aggression, Maltreatment & Trauma, 15(1), 59–75, 2007; Dobash and Dobash 2000; Feder et al. 2008; Gerbert et al. Journal of Family Practice, 49(10), 889–895, 2000; Wathen and MacMillan. Journal of the American Medical Association, 289(5), 589–600, 2003). This article presents a brief overview of the historical evolution and development of these discrete perspectives and identifies and assesses current collaborative interventions rooted in these historical precedents. In conclusion, the authors provide a summative discussion of the most current findings of research into IPV interventions, with a particular focus on the changing roles of race and gender in both the criminal prosecution of IPV and services provided to IPV perpetrators and victims.     

Incidence and Correlates of Posttraumatic Stress Disorder in Australian Victims of Domestic Violence

In recent years, evidence has emerged of the significant incidence of posttraumatic stress disorder (PTSD) among victims of domestic violence. The present study examined incidence and correlates of PTSD in 100 female victims of domestic violence resident in women's shelters in Adelaide, South Australia. Forty-five women were found to meet all diagnostic criteria for PTSD. Women meeting PTSD diagnostic criteria reported having experienced higher levels of violence and were more likely to report having a spouse with an alcohol problem and having believed they would be killed by their spouse than women who did not meet criteria. Diagnosis of PTSD was also associated with higher levels of anxiety and depression.

4F‐MDMB‐BINACA: A New Synthetic Cannabinoid Widely Implicated in Forensic Casework

This is the first report regarding the characterization of the new synthetic cannabinoid 4F‐MDMB‐BINACA. 4F‐MDMB‐BINACA was first analytically confirmed in seized drug material using gas chromatography–mass spectrometry (GC‐MS), liquid chromatography–quadrupole time‐of‐flight mass spectrometry (LC‐QTOF), and nuclear magnetic resonance (NMR) spectroscopy. Subsequent to this characterization, 4F‐MDMB‐BINACA was detected in biological specimens collected as part of forensically relevant casework, including medicolegal death investigations and drug impaired driving investigations, from a variety of regions in the United States. Further analysis of biological specimens resulted in the identification of the metabolites 4F‐MDMB‐BINACA 3,3‐dimethylbutanoic acid and 4‐OH‐MDMB‐BINACA. 4F‐MDMB‐BINACA is appearing with increasing frequency as a contributory factor in deaths, creating morbidity and mortality risks for drug users. Laboratories must be aware of its presence and impact, incorporating 4F‐MDMB‐BINACA into workflows for detection and confirmation.
