Rates of violence in patients classified as high risk by structured risk assessment instruments
TLDR
After controlling for time at risk, the rate of violence in individuals classified as high risk by SRAIs shows substantial variation and assigning predetermined probabilities to future violence risk on the basis of a structured risk assessment is not supported by the current evidence base.Abstract:
Background
Rates of violence in persons identified as high risk by structured risk assessment instruments (SRAIs) are uncertain and frequently unreported by validation studies.
Aims
To analyse the variation in rates of violence in individuals identified as high risk by SRAIs.
Method
A systematic search of databases (1995-2011) was conducted for studies on nine widely used assessment tools. Where violence rates in high-risk groups were not published, these were requested from study authors. Rate information was extracted, and binomial logistic regression was used to study heterogeneity.
Results
Information was collected on 13 045 participants in 57 samples from 47 independent studies. Annualised rates of violence in individuals classified as high risk varied both across and within instruments. Rates were elevated when population rates of violence were higher, when a structured professional judgement instrument was used and when there was a lower proportion of men in a study.
Conclusions
After controlling for time at risk, the rate of violence in individuals classified as high risk by SRAIs shows substantial variation. In the absence of information on local base rates, assigning predetermined probabilities to future violence risk on the basis of a structured risk assessment is not supported by the current evidence base. This underscores the need for caution when such risk estimates are used to influence decisions related to individual liberty and public safety.read more

TL;DR: It is suggested that violence risk assessment is a global phenomenon, as is the use of instruments to assist in this task, and improved feedback following risk assessments and the development of risk management plans could improve the efficacy of health services.

TL;DR: These Practice Guidelines for the Psychiatric Evaluation of Adults mark a transition in the American Psychiatric Association’s Practice Guidelines by using a “snowball” survey methodology to identify experts on psychiatric evaluation and solicit their input on aspects of the psychiatric evaluation that they saw as likely to improve specific patient outcomes.

Communicating the results of criterion referenced prediction measures: Risk categories for the Static-99R and Static-2002R sexual offender risk assessment tools
TL;DR: It is found that the new, common STATIC risk categories not only increase concordance of risk classification (from 51% to 72%)—they also allow evaluators to make the same inferences for offenders in the same category regardless of which instrument was used to assign category membership.

TL;DR: It is found that the evidence base for forensic-psychiatric practice is weak though there is some evidence to suggest that psychiatric care produces better outcomes than criminal justice detention only.

TL;DR: A prediction model in a Swedish prison population that can assist with decision making on release by identifying those who are at low risk of future violent offending, and those at high risk of violent reoffending who might benefit from drug and alcohol treatment is developed.

Use and Misuse of the Receiver Operating Characteristic Curve in Risk Prediction
TL;DR: The c statistic, or area under the receiver operating characteristic (ROC) curve, achieved popularity in diagnostic testing, in which the test characteristics of sensitivity and specificity are relevant to discriminating diseased versus nondiseased patients, may not be optimal in assessing models that predict future risk or stratify individuals into risk categories.
