Differentiating patterns of substance misuse by subtypes of antisocial traits in male offenders

Among criminal offenders, two subtypes of antisocial traits, psychopathy and externalizing-only, are associated with an especially elevated risk for substance use disorders (SUDs). The present study examined the associations of these traits with patterns of substance misuse. In a sample of 1410 male offenders, we used diagnoses for alcohol, cannabis, opioids, and stimulants to examine the association between antisocial traits and SUD severity, as well as, age at substance use initiation. Results indicated that externalizing-only, but not psychopathic, traits predicted greater severity of SUDs (i.e. increased likelihood of dependence) across all substances. By contrast, psychopathic, but not externalizing-only, traits predicted earlier initiation of use across all substances. These differential patterns of substance misuse may be a reflection of distinct psychobiological processes. Ultimately, parsing the patterns of substance use across a continuum of clinically heterogeneous samples, rather than within circumscribed diagnostic categories, might help to refine the phenotype and improve the prediction of substance-related problems.     

On national and cultural boundaries: a cross-cultural approach to sexual violence perpetration in Brazil and the United Kingdom

The majority of research on rape has so far neglected to examine the effects of socio-cultural beliefs and practices on sexual violence perpetration, with most authors dedicating themselves, instead, to an individualistic approach of this phenomenon. Although these approaches are certainly valid, they often ignore how these behaviours are embedded in the culture and, as a result, do not adequately explore the causes and consequences of sexual violence perpetration. Therefore, the primary goal of this review is to redress this deficiency, focusing on the connection between the phenomenon and the cultural backdrop against which it occurs. Hence, a discussion around certain factors that may serve to either legitimise or to condemn sexual violence in two different countries (Brazil and UK) is necessary. To make this possible, differences regarding each country’s culture, rape legislation and prevalence are presented, and issues regarding the current individualistic theoretical approach to the subject are explored.     

Examining the Incidence of and Time to Recidivism Within the Risk Contingency Framework: A 20-Year Follow up Study

This study examined the extent to which the contingencies risk framework (consisting of dispositional, historical, contextual, and clinical domains) predicted detected recidivism (i.e., arrest or conviction). Secondary data were extracted on 413 prisoners who underwent a psychiatric evaluation, were assessed on the risk domains, and followed up over 20 years. There were 273 (66.1%) cases of recidivism for serious offenses (e.g., assaults). Criminal career outcomes examined included: years to and the incidence of recidivism. Statistics showed that chance classification of the incidence of recidivism was 21% more accurate for the recursive partitioning than the bilinear model. These results are consistent with the contingencies risk framework, support its use over linear models, and highlight its predictive utility.     

A diflunisal related fatality: a case report

A case is reported where the death of an individual resulted from the ingestion of diflunisal. Diflunisal was identified by a combination of liquid chromatography, UV spectrophotometry and colorimetry. Diflunisal was quantified in blood (260 mg/l), bile (71 mg/l), kidney (350 mg/kg), liver (400 mg/kg), stomach contents (34 mg) and urine (78 mg/l). No previous literature references discussing diflunisal related fatalities were available.
