The SVR-20 is a 20-item checklist of risk factors for sexual violence that were identified by a review of the literature on sex offenders. The checklist was developed to improve the accuracy of assessments for the risk of future sexual violence. Sexual violence is defined broadly as "actual, attempted, or threatened sexual contact with a person who is nonconsenting or unable to give consent." The goals of the SVR-20 guidelines include the following:
Make risk assessments more systematic.
Increase agreement among evaluators.
Provide detailed guidelines grounded in the scientific literature.
Assist in the planning and delivery of interventions (treatment and supervision).
Objectively evaluate the adequacy of risk assessments.
Risk assessment does not fall exclusively within the domain of any profession or discipline. Risk assessments are routinely conducted by correctional, psychological, and medical professionals, as well as by multidisciplinary teams. Evaluators need to understand the factors associated with general crime and violence as well as those associated with sexual violence. The SVR-20 manual provides information about how and when to conduct sexual violence risk assessments, research on which the basic risk factors are based, and key questions to address when making judgments about risk.
The SVR-20 specifies which risk factors should be assessed and how the risk assessment should be conducted. The list of risk factors is: (a) empirically related to future sexual violence; (b) useful in making decisions about the management of sex offenders; (c) nondiscriminatory; and (d) reasonably comprehensive without being redundant. The 20 factors essential in a comprehensive sexual violence risk assessment fall into three main categories: Psychosocial Adjustment, History of Sexual Offenses, and Future Plans. The actual risk for sexual violence depends on the combination (not just the number) of risk factors present in a specific case. Coding of the SVR-20 involves determining the presence/absence of each factor and whether there has been any recent change in the status of the factor. This item-level information is integrated into a summary judgment of the level of risk (Low, Moderate, or High), which can easily be translated into an action plan.
Developed primarily for use in criminal and civil forensic contexts, the SVR-20 is appropriate for use in cases where an individual has committed, or is alleged to have committed, an act of sexual violence:
Pretrial release decisions.
Presentence assistance to judges.
Development of treatment programs at correctional intake.
Prior to discharge to assist in post-release management.
Determination of need for a community warning.
Quality assurance or critical incident reviews.
Education and training. The HCR- 20 is a 20-item checklist to assess the risk for future violent behaviour in criminal and psychiatric populations. Items were chosen based on a comprehensive review of the literature and input from experienced forensic clinicians. The HCR-20 includes variables which capture relevant past, present, and future considerations and should be regarded as an important first step in the risk assessment process. The professional(s) completing the HCR-20 Coding Sheet must first determine the presence or absence of each of the 20 risk factors according to three levels of certainty (Absent, Possibly Present, Definitely Present).
20 Items are divided into Three Sections
- 10 Historical Items (previous violence, age at first violent offence, family and vocational background, and more).
- 5 clinical Items (current symptomatology and psychosocial adjustment).
- 5 Risk Management Items (release and treatment plan, and necessary services and support).
The final judgement regarding the risk for future violence (Low, Moderate, High) should be based on a careful analysis of the 20 risk factor items.
Any statement of risk should take into consideration the base rate of violence in the particular or setting (e.g., low, moderate, or high risk relative to other correctional inmates).
HCR-20 Violence Risk Management Companion Guide
This handy volume provides brief descriptions of violence intervention strategies. Section One covers general issues pertaining to violence risk assessment and management using the HCG-20. Section Two suggests intervention and management strategies that stem from the Clinical (“C”) factors of the HCR-20. Section Three addresses strategies that stem from the Risk Management (“R”) factors. Section Four offers practical assistance to people interested in using the HCR-20 for planning and tracking risk management activities.
