Are risk assessment tools more accurate than unstructured judgments in predicting violent, any, and sexual offending? A meta‐analysis of direct comparison studies
We conducted a pre‐registered meta‐analysis of studies that directly compared the predictive validity of risk assessment tools to unstructured judgments of risk for violent, any, or sexual offending. A total of 31 studies, containing 169 effect sizes from 45,673 risk judgments, met inclusion criteria. Based on the results of three‐level mixed‐effects meta‐regression models, the predictive validity of total scores on risk assessment tools was sign…
Violence risk assessment of Sovereign Citizens
Sovereign Citizens comprise an understudied right‐wing extremist movement in the United States who have grown in notoriety in recent years due to several high‐profile instances of violence. Despite this, little empirical research has been conducted on Sovereign Citizens, including research on assessing their risk for violence. In this study, we sought to replicate and extend a prior study on Sovereign Citizen violence. Using open‐source data, we …
Do structured risk assessments predict violent, any, and sexual offending better than unstructured judgment? An umbrella review
Although it is widely believed that risk assessment tools lead to more accurate estimates of risk of violence and offending than unstructured clinical judgments, the nature and quality of evidence that supports this view is unclear. As such, we conducted an umbrella review of systematic reviews. Through a search of 15 databases, we identified nine systematic reviews, including six meta-analyses and three narrative systematic reviews, that compare…
Interrater reliability, concurrent validity, and predictive validity of the risk for sexual violence protocol
OBJECTIVE: This study empirically evaluated risk judgments made using the Risk for Sexual Violence Protocol (RSVP; Hart et al., 2003), a widely used set of structured professional guidelines for assessing and managing sexual violence risk. HYPOTHESIS: Based on evaluations of other structured professional judgment guidelines, we hypothesized that judgments made using the RSVP would demonstrate good interrater reliability, concurrent validity, and …
