Identify presence/absence of violence risk factors.


The HCR-20 is a 20-item checklist to assess the risk for future violent behavior in criminal and psychiatric populations. The HCR-20 should be regarded as an important first step in the risk assessment process. The manual provides information about how and when to conduct violence risk assessments, research on which the basic risk factors are based, and key questions to address when making judgments about risk. The 20 Items are divided into three sections: • 10 Historical Items (previous violence, age at first violent offense, family and vocational background, etc.) • Five Clinical Items (current symptomatology and psychosocial adjustment) • Five Risk Management Items (release and treatment plan, necessary services and support). Historical information serves as an anchor for risk assessments because there is a strong predictive link between past and future violent behavior. Such information should be verified carefully, as historical considerations may modify analyses of clinical and situational factors. In some cases, it may be necessary to contact friends or family members of the individual for verification of past events. The five clinical variables can be assessed at regular intervals so that risk level may be modified accordingly. The risk management items focus on predicting how individuals will adjust to future circumstances, and this is directly related to the context within which the individual will be living. The final judgment regarding the risk for future violence (Low, Moderate, High) should be based on a careful analysis of the 20 risk factor items. Any statements of risk should take into consideration the base rate of violence in the particular population or setting (e.g., low, moderate, or high risk relative to other correctional inmates).

Information about the new edition:

  • Built on the solid foundation laid by versions 1 and 2, the HCR-20 V3 embodies and exemplifies the structured professional judgment (SPJ) model of violence risk assessment.
  • Commonly used within correctional, forensic, and general or civil psychiatric settings, both institutional and community-based.
  • Allows you to determine the presence of 20 key violence risk factors in your client and their relevance to that client.
  • Contains information to help you construct meaningful formulations of violence risk, future risk scenarios, appropriate risk management plans, and informative communication of risk.
  • Subjected to exhaustive testing and evaluations, this revision is expected to be even more clinically useful than its predecessor while still enjoying a solid empirical basis.
