“…This methodology breaks down individuals into groups based on the factors that best discriminate between recidivators and non-recidivators, so that a progressive two by two branching of risk factors and individuals into lower and higher risk groups occurs (Monahan et al, 2001). Nicholls, & Grant, 1999). Additionally, it is becoming more common for clinicians to utilize the HCR-20 in their risk assessments (Webster et al, 1997).…”

Past research examining the effects of actuarial and clinical expert testimony on defendants' dangerousness in Texas death penalty sentencing has found that jurors are more influenced by less scientific pure clinical expert testimony and less influenced by more scientific actuarial expert testimony (Krauss & Lee, 2003; Krauss & Sales, 2001). By applying cognitive–experiential self‐theory (CEST) to juror decision‐making, the present study was undertaken in an attempt to offer a theoretical rationale for these findings. Based on past CEST research, 163 mock jurors were either directed into a rational mode or experiential mode of processing. Consistent with CEST and inconsistent with previous research using the same stimulus materials, results demonstrate that jurors in a rational mode of processing more heavily weighted actuarial expert testimony in their dangerousness assessments, while those jurors in the experiential condition were more influenced by clinical expert testimony. The policy implications of these findings are discussed. Copyright © 2004 John Wiley & Sons, Ltd.

“…Although it is a structured professional judgement risk assessment instrument and clinicians are discouraged from summing individual item scores to produce a total score, for research purposes a total sore may be calculated. The predictive validity of the HCR-20 has been demonstrated in numerous studies (Douglas, Ogloff, Nicholls, & Grant, 1999;Gray, Fitzgerald, Taylor, MacCulloch, & Snowden, 2007; for review see Douglas, Shaffer, Blanchard, Guy, Reeves, & Weir, 2002.…”

This study examined the impact of an intensive inpatient violent offender treatment programme, Life Minus Violence -Enhanced (LMV-E, Ireland, 2008), on intermediary treatment targets, risk for violence, and aggressive behaviour during treatment in a sample of male mentally disordered offenders. Using quasi-experimental design, offenders who completed LMV-E and a comparison group showed reduced problems with impulsivity and anger regulation and improvements in social problem solving.Aggregate risk for future violence lessened in both treatment and comparison groups, although by a significantly greater degree for the comparison group. The aggressive behaviour of both groups reduced. Completion of the LMV-E conferred additional improvements in some facets of social problem solving and anger regulation. Neither group showed improvements in empathic responses, coping skills or problematic interpersonal style. Overall, these results suggest anger regulation, impulsivity and social problem solving are most amenable to change, that reductions in certain facets of these dynamic risk factors transpires with nonspecific psychiatric inpatient treatment, but that the LMV-E, a cognitive behavioural violence specific psychological treatment, confers greater change in some facets of social problem solving and anger regulation.

Psychosis and Violence: Stories, Fears, and Reality

Individuals with psychosis are often feared. In fact, they are themselves likely to be victims of violence; however, the main aim of this review is to provide an overview of the evidence on relations between psychosis and violence to others. The terms psychosis and violence were used in a literature search limited to the Cochrane Library and PubMed, a manual search of 8 journals, and a follow-up of additional references in the articles found. The overview draws on new empirical data and major reviews. Almost all sound epidemiologic data on psychosis and violence dates from 1990. There is consistency on a small but significant relation between schizophrenia and violent acts. Since then there has also been movement toward understanding the nature of associations and progress on strategies for managing individuals who have psychosis and are violent. Public fears about individuals with psychotic illnesses are largely unfounded, although there would be benefit in greater attention to the safety of those in their close social circle. The task for the next 10 years must be the development and application of knowledge to improve specific treatments—that is, interventions that go beyond holding and caring to bring about substantial change.
