Violence Risk (violence + risk)
Selected AbstractsThe significance of protective factors in the assessment of riskCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 1 2010Charlotte E. Rennie Background,Few studies have explored protective factors in the assessment of risk, despite acknowledgement that protective factors may play an important role. Aim,To examine the significance of protective factors in assessment of risk using the Structured Assessment of Violence Risk in Youth (SAVRY). Method,The SAVRY was completed on 135 male adolescents in custody in the UK. Data on previous offending and childhood psychopathology were collected. Participants were prospectively followed up at 12 months using data from the Home Office Police National Computer (HOPNC). Results,Participants with protective factors were older when first arrested, were less prolific offenders and had fewer psychopathological problems. The number of protective factors present was significantly higher for participants who did not re-offend during the follow-up. The total number of SAVRY protective factors significantly predicted desistance at follow-up and resilient personality traits constituted the only significant individual protective factor. Conclusions and implications,Protective factors might buffer the effects of risk factors and a resilient personality may be crucial. Recognition of protective factors should be an essential part of the risk management process and for interventions with high-risk adolescents to reduce re-offending.

[source] The effect of discordance among violence and general recidivism risk estimates on predictive accuracyCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 3 2006Jeremy F. Mills Introduction,Previous research has shown that the prediction of short-term inpatient violence is negatively affected when clinicians' inter-rater agreement is low and when confidence in the estimate of risk is low. This study examined the effect of discordance between risk assessment instruments used to predict long-term general and violence risk in offenders. Methods,The Psychopathy Checklist , Revised (PCL,R), Level of Service Inventory , Revised (LSI,R), Violence Risk Appraisal Guide (VRAG), and the General Statistical Information on Recidivism (GSIR) were the four risk-prediction instruments used to predict post-release general and violent recidivism within a sample of 209 offenders. Results,The findings lend empirical support to the assumption that predictive accuracy is threatened where there is discordance between risk estimates. Discordance between instruments had the impact of reducing predictive accuracy for all instruments except the GSIR. Further, the influence of discordance was shown to be greater on certain instruments over others. Discordance had a moderating effect on both the PCL,R and LSI,R but not on the VRAG and GSIR. Conclusions,There is a distinct advantage when attempting to predict recidivism to employing measures such as the LSI-R, which includes dynamic variables and intervention-related criminogenic domains, over a measure purely of fixed characteristics, such as the GSIR; however, if there is discordance between the risk estimates, caution should be exercised and more reliance on the more static historically based instrument may be indicated.

Palmstierna Objective:, To simultaneously evaluate actuarial and dynamic predictors of severe in-patient violence among women involuntarily admitted for severe drug abuse. Method:, All patients admitted to special facilities for involuntary treatment of absconding-prone, previously violent, drug abusing women in Sweden were assessed with the Staff Observation Aggression Scale, revised. Actuarial data on risk factors for violence were collected and considered in an extended Cox proportional hazards model with multiple events and daily assessments of the Broset Violence Checklist as time-dependent covariates. Results:, Low-grade violence and being influenced by illicit drugs were the best predictors of severe violence within 24 h. Significant differences in risk for violence between different institutions were also found. Conclusion:, In-patient violence risk is rapidly varying over time with being influenced by illicit drugs and exhibiting low-grade violence being significant dynamic predictors. Differences in violence between patients could not be explained by patient characteristics. [source] SCL-90-R profiles in a sample of severely violent psychiatric inpatientsAGGRESSIVE BEHAVIOR, Issue 6 2002Stål Bjørkly Abstract A sample of 39 patients who had committed serious violent acts toward others were assessed with the revised Symptom Checklist (SCL-90-R). The SCL-90-R is a self-report symptom inventory for the measurement of psychopathology in psychiatric and medical patients. In addition to the patients' self-report, an observer-rated SCL-90-R was obtained. This was accomplished by letting one pair of nurses complete SCL-90-R ratings for each patient. The first aim of the study was to compare the SCL-90-R self-report scores of the patient sample with the psychiatric inpatient norms [Derogatis LR (1992): Clinical Psychometric Research Inc]. Another purpose of this study was to explore possible trends of discordance between the observer ratings and the self-reports of the study group. Always considering the limitations of the small sample, it was nevertheless also of interest to look for possible sex differences and differences between violent subgroups and between diagnostic groups in the self-reported scores as well as in the observer ratings. The most striking findings of the present study were that the self-reported scores were lower than the inpatient norms for SCL-90-R and that the patients' self-reported levels of distress were significantly lower than those found in the observer ratings. Underreporting of psychopathology as a marker of violence risk is discussed in light of these findings. In this study, women reported higher distress levels than men in the Interpersonal Sensitivity symptom dimension. There were no significant differences concerning SCL-90-R ratings between patients who had committed homicide, attempted homicide, or physically assaulted another person in a serious but not life-threatening way.

Elbogen Although empirical research has examined factors associated with increased violence risk among individuals with severe mental illness (SMI) and among veterans without SMI, less attention has been devoted to identifying violence risk factors among veterans with SMI. Using multivariable analysis of a large pooled sample of individuals with SMI, this study examines violence risk factors of N = 278 veterans with SMI. In multivariate modeling, violence by veterans with SMI was associated with head injury, posttraumatic stress disorder (PTSD), substance abuse, and homelessness. Results support the view clinicians assessing violence risk among veterans with SMI should consider a combination of characteristics empirically related to violence by non-veterans with SMI (e.g., homelessness) and veterans without SMI (e.g., PTSD). [source] Chronic Pain and Violent Ideation: Testing a Model of Patient ViolencePAIN MEDICINE, Issue 3 2007Daniel Bruns PsyD ABSTRACT Objective., Physicians are at risk of patient-perpetrated violence. The objective of this study was to test a clinical model of patient violence, which had been developed previously by Fishbain and colleagues. The developers of this model believed that it would be associated with increased risk of violence in pain patients. Design., Hypotheses generated by the model were tested using manova and chi-square procedures. Setting., A total of 527 subjects for this study were patients obtained from 90 medical facilities in 30 U.S. states. Patients., All subjects were patients being treated for injury and nonmalignant pain. All of the subjects were adults, ranging in age from 18 to 65 years, and were able to read at the sixth-grade level. The demographics of the sample approximated U.S. Census data for race, education, age, and gender. Results., The results included findings that violent ideation was associated with higher levels of physical difficulties, including pain (P = 0.01), problems with functioning (P = 0.0003), and somatic complaints (P = 0.0001). Significant psychosocial variables included hostility (P < 0.0001), dependency (P < 0.0001), substance abuse (P < 0.0001), litigation (P < 0.001), and a lack of trust in the physician (P < 0.001). Conclusions., Using the Battery for Health Improvement 2 as a measure, the findings of this study consistently supported the Fishbain Model of violence risk, and also reinforced the need for psychological assessment and management when working with chronic pain patients. Suggestions for intervention were also offered, but further research will be necessary to see whether these interventions are effective in decreasing patient violence. [source] Cognitive-behavioural rehabilitation of high-risk violent offenders: Investigating treatment change with explicit and implicit measures of cognitionAPPLIED COGNITIVE PSYCHOLOGY, Issue 3 2010Devon L. L. Polaschek Important as it is both to risk of re-offending and to cognitive behavioural treatment, violent cognition is seldom measured in rehabilitation programmes, and even more rarely linked to measures of violence risk. Most often, researchers measure violent cognition by having offenders complete transparent self-report questionnaires. This approach may be flawed both by socially desirable responding and by theoretical speculation that stronger links exist between automatic rather than explicit, consciously deliberated cognition and violent behaviour. We measured violent cognition in several ways; collecting data with two self-report scales, along with two Implicit Association Tests (IATs) from men commencing and completing an intensive cognitive-behavioural rehabilitation programme for high-risk violent prisoners. We addressed the questions of whether these two forms of assessment,explicit and implicit,are related, and which is most strongly linked to estimates of violence, based on the Violence Risk Scale. Explicit and implicit tests were not related to each other, although both self-report scales, and one of the IATs elicited significantly more pro-social responses following treatment. Further, the Aggression Questionnaire (AQ) scores were significantly correlated with dynamic risk both pre- and post-programme, while post-programme, scores on one of the two IATs was significantly correlated with dynamic and static risk, as measured pre- and post-programme. These findings suggest that implicit and explicit measures may be assessing different aspects of cognition, and only some are related to violence risk. Copyright © 2010 John Wiley & Sons, Ltd. [source] Juror decision-making in a mock sexually violent predator trial: gender differences in the impact of divergent types of expert testimony,BEHAVIORAL SCIENCES & THE LAW, Issue 2 2003Laura S. Guy M.A. Despite widespread use of mental health testimony in cases where violence risk is at issue, relatively little is known about the impact of such information on juror decision-making. This study addressed the effects of testimony based on three types of risk assessment instrument or method (clinical opinion, actuarial assessment, and ratings of psychopathy) to examine whether they would have differential impact on jurors' perceptions of the defendant. In a mock sexually violent predator civil commitment trial, 172 undergraduates were presented a case summary that included prosecution and defense expert testimony related to violence risk based on one of the three methods noted above. Consistent with earlier research, the hypothesis that a defendant described as a "high risk psychopath" by the prosecution would be judged more severely than a defendant judged as "high risk" based on other evaluation procedures was supported, but only among female jurors. Unlike prior studies, little support was found for the hypothesis that clinical opinion testimony would be more influential than actuarially based testimony for either gender. Mechanisms that may underlie the observed gender differences are discussed, as are the potential implications of these findings for civil commitment proceedings. Copyright © 2003 John Wiley & Sons, Ltd. [source] Assessing violence risk in Tarasoff situations: a fact-based model of inquiry,BEHAVIORAL SCIENCES & THE LAW, Issue 3 2001Randy Borum Psy.D. Although significant advances in risk assessment research and practice have been made in recent years, there has not been any analysis in the professional literature regarding how and whether the emerging practice recommendations apply in Tarasoff -type situations. We suggest that, when faced with a Tarasoff -type situation, the appraisal of risk should be guided by a method that is primarily fact-based and deductive, rather than by the more inductive risk assessment approach for general violence recidivism, which is guided primarily by base rates and historical risk factors. We review the principles underlying a fact-based, or threat assessment, approach and outline six areas of inquiry that can guide the appraisal of risk: A,attitudes that support or facilitate violence, C,capacity, T,thresholds crossed, I,intent, O,other's reactions, and N,noncompliance with risk reduction interventions.
