The Effect of Negative Media Exposure and Evaluators’ Attitudes Toward Offenders on Violence Risk Assessment with the HCR-20V3
Structured risk assessment instruments (SRAIs), such as the Historical Clinical Risk Management (HCR-20V3) are increasingly used to inform criminal justice decision-making, highlighting the significance of examining the potential for bias when using these measures and effective strategies to mitigate it. In this experimental study, we examined the possible biasing effects of (1) negative pretrial publicity (PTP) about a person who committed a double homicide and (2) evaluators’ attitudes toward offenders, on scale scores and final risk judgments of the HCR-20V3. Participants (N = 54) included graduate students, clinicians, and researchers who had been trained to complete the HCR-20. Contrary to expectation, negative PTP exhibited no effects on the HCR-20 total scores, subscale scores, or final risk judgments. In line with our hypothesis, more positive attitudes toward offenders were predictive of lower HCR-20 total scores and lower ratings on the Clinical and Risk Management subscales and final risk judgment of imminent violence. These findings add to a growing body of research indicating forensic risk evaluations conducted using SRAIs are not immune to the effects of some types of bias.
