Some notes on the validation of VRS-SO static scores

ABSTRACT

The present study was a psychometric examination of Violence Risk Scale-Sexual Offender version (VRS-SO; Wong, S., Olver, M. E., Nicholaichuk, T. P., & Gordon, A. (2003 Wong, S., Olver, M. E., Nicholaichuk, T. P., & Gordon, A. (2003). The violence risk scale: Sexual offender version (VRS-SO). Saskatoon: Regional Psychiatric Centre and University of Saskatchewan. [Google Scholar]). The violence risk scale: Sexual offender version (VRS-SO). Saskatoon: Regional Psychiatric Centre and University of Saskatchewan) static item scores in a Canadian multisite sample of 668 treated adult male sexual offenders. Exploratory factor analysis (EFA) of 13 nonredundant Static-99R and VRS-SO static items generated three factors labelled Youthful Aggression, Sexual Criminality, and General Criminality. The factor and total scores converged with Static-99R and VRS-SO dynamic factor scores. Scores on the VRS-SO static items, EFA-derived factors, and total score each significantly predicted 5- and 10-year sexual, violent, and general recidivism through ROC analyses. Cox regression survival analyses showed all three factors uniquely predicted sexual recidivism to varying degrees in the overall sample; however, only Youthful Aggression and General Criminality uniquely significantly predicted violent and general recidivism in the overall sample and among sexual offender subgroups. Implications for theory, clinical practice, and instrument refinement are discussed.     

Mapping an agenda for the study of youth sexual aggression in Europe: assessment,principles of good practice,and the multilevel analysis of risk factors

ABSTRACT

Sexual aggression is a serious threat to young people's sexual health in Europe, but establishing the exact scale of the problem has been hampered by a variety of conceptual and methodological problems. This article presents a framework for studying youth sexual aggression that addresses both prevalence and risk factors of victimisation and perpetration. It proposes a research tool to comprehensively assess the perpetration of, and victimisation by, sexual aggression that captures different coercive strategies, sexual acts, victim–perpetrator relations, and gender constellations. The instrument is rooted in a clear conceptual definition of sexual aggression and was pilot-tested in 10 countries of the European Union (EU). Furthermore, a list of good practice criteria is proposed to promote the quality and comparability of research on youth sexual aggression in Europe. A multilevel approach combining individual-level and country-level predictors of sexual aggression is outlined and illustrated with data from the pilot study in 10 countries.     

Young adult sexual offenders with emerging personality disorders: developmental and offence-related characteristics and treatment engagement

ABSTRACT

In the context of the UK Government’s Offender Personality Disorder (OPD) Strategy, large numbers of high-risk young adult sexual offenders with emerging personality disorders are being screened for inclusion onto specialist intervention pathways (the OPD Pathway). However, little is currently known about the clinical and offence-related needs of this population or their impact on treatment engagement. The current study investigated the developmental, personality and offence-related characteristics of 87 incarcerated young adult sexual offenders, comparing those screened in to the pathway and those not screened in. Fifty per cent of the sample were potentially eligible for the OPD pathway. OPD eligible cases were found to have significantly higher rates of parental difficulties, developmental trauma, and childhood behavioural difficulties and to present with significantly higher rates of previous violent and sexual offences, previous allegations of sexual offences, and to have used physical coercion in their offences. The OPD sample was also significantly less likely to have pre-pubescent victims and more likely to refuse treatment, with over 70% failing to engage with the Sex Offender Treatment Programme (SOTP). SOTP non-engagement among OPD cases was most strongly predicted by categorical offence denial. Comparisons are made with the broader adolescent sexual offender literature.     

Factors associated with contact child sexual abuse in a sample of indecent image offenders

Abstract

This study explored a sample of 244 UK adult male offenders convicted of offences involving indecent images of children (IIOC): 120 had a previous contact child sexual offence (defined as dual offenders) and 124 had no evidence of an offence against a child (defined as non-contact offenders). Offender groups were compared regarding their socio-demographic characteristics, previous convictions and IIOC possession. Key discriminatory factors that differentiated dual offenders were: access to children, previous offence history, sexual grooming and possession of IIOC that depicts similar-aged victims. In contrast, non-contact offenders could be identified from their greater amount and wider range of IIOC possession. The results suggest a homology between Internet behaviours, IIOC possession and victim selection. Implications for law enforcement agencies are discussed in terms of assisting investigative prioritisation by identifying those most at risk of committing sexual abuse against children.     

Sexual recidivism: A review of static,dynamic and actuarial predictors

The need for accurate risk assessment of sexual offence recidivism has never been greater. It is widely accepted that actuarial risk instruments outperform clinical judgement and the literature has recently witnessed a surge of empirically derived actuarial measures. However, in spite of the increased levels of predictive accuracy, actuarial measures have been criticized as being unrepresentative, lacking specificity, and being heavily reliant on static risk factors without taking into account dynamic risk, psychological emotional states and treatment effects. Rather than offering a critique of the actuarial movement, this paper offers a summary of static and dynamic risk factors associated with sexual offence recidivism as identified from the literature. Implications of incorporating dynamic factors into risk assessments and actuarial measures are discussed.     

Multiplex high resolution melt (HRM) messenger RNA profiling assays for body fluid identification

Traditional body fluid identification methods use a variety of technologically diverse techniques that do not permit the identification of all body fluids. Definitive identification of the biological material present can be crucial to a fuller understanding of the circumstances pertaining to a crime. Thus definitive molecular based strategies for the conclusive identification of forensically relevant biological fluids need to be developed. Messenger (mRNA) profiling is an example of such a molecular based approach.Current mRNA body fluid identification assays typically involve either capillary electrophoresis (CE) or quantitative RT-PCR (qRT-PCR) platforms, each with its own limitations. Both platforms require the use of expensive fluorescently labeled primers or probes. CE-based assays require separate amplification and detection steps thus increasing the time required for analysis. For qRT-PCR assays, only 3 or 4 markers can be included in a single reaction since each requires a different fluorescent dye. To simplify mRNA profiling assays and to reduce the time and cost of analysis, we have developed multiplex high resolution melt (HRM) assays that provide an identification of all forensically relevant biological fluids and tissues.     

Effective Communication and Frame Persuasiveness for Food Safety Controversies： The Young Male Consumer＇s Perspective

This study explored effective risk communication for food safety targeting young male consumers who frequently dine outside by examining the controversy of US beef importation in Taiwan in 2012. Guided by risk perception theory and framing theory in issues management, the researcher developed a risk profile of young male consumers based on interview data. Persuasiveness of message frames used by the government was analyzed according to three distinct communicative objectives： to reduce risk perception, to motivate beef consumption, and to gain support for beef importation. The study suggested that the young male consumer＇s knowledge of US beef was formed by news reports and information from family members with experts as the most trusted source. They perceived US beef as risky but safe to eat if they wished. They seldom actively sought information about the beef. The new media were the most used by them for seeking and receiving such information. Frame persuasiveness varied across communicative objectives and was associated with the schemata employed in the configuration of risk-benefit trade-offs for each targeted behavior.
