Violence Risk Assessment in a Prison Setting
Mr. S is a 35-year-old incarcerated man with a history of violent assaults in prison. He has been diagnosed with antisocial personality disorder and substance use disorder (in remission). He is up for parole in 6 months. The parole board requests a violence risk assessment. The psychologist has access to institutional records showing 4 physical fights in the past 2 years, but no detailed incident reports. The psychologist uses the HCR-20 V3 and finds several historical risk factors, but limited current clinical factors. The psychologist has only one 90-minute interview and no collateral from correctional officers.
1. What are the ethical and practical considerations in conducting this violence risk assessment?
Read the worked answer
Ethically, the psychologist must obtain informed consent (unless waived by legal mandate), clarify the purpose (parole decision) and limits of confidentiality. Practically, the lack of collateral information and incident details is a significant limitation. The psychologist should attempt to obtain incident reports and interview correctional officers. If unavailable, the psychologist must document the limitation and avoid overconfidence in the risk estimate. The HCR-20 V3 requires integration of historical, clinical, and risk management factors. With limited clinical factors, the psychologist may rely more on historical and future risk management items. The psychologist should use multiple methods (e.g., PCL-R, static measures) but note that static measures alone are insufficient. The report should clearly state the limitations and provide a range of risk, not a precise probability.
2. How should the psychologist communicate the risk level and recommendations to the parole board?
Read the worked answer
The psychologist should provide a structured professional judgment (SPJ) of risk (low, moderate, high) with a narrative explaining the factors. The report should distinguish between likelihood of violence and potential severity. Recommendations should be specific: e.g., participation in anger management, substance abuse treatment, monitoring, and avoidance of known triggers. The psychologist should avoid making the ultimate decision (parole) but can offer opinions on risk management needs. The report should acknowledge the base rates for violence in similar populations and the limitations of the assessment. The psychologist should be prepared to testify and explain the methodology and limitations.
