A comparison of two structured professional judgment tools for violent extremism and their relevance in the French context

Abstract

France has repeatedly been hit by terrorist attacks making the use of a structured professional judgement tool essential. Two such tools currently are used in Europe: VERA (Canada) and ERG 22+ (England and Wales). We compare these tools to assess which one would better suit the French context. We find that they have a lot in common in terms of their general content and intrinsic value. However, VERA's main understanding of terrorism is ideology, whereas ERG's perceives it as being essentially about identity. ERG was the first tool to introduce a measure for psychopathology; only VERA contains a list of protective factors. The two instruments were developed in similar ways with, for ERG, more emphasis on extremist offenders' casework. Crucially, ERG 22+ has been developed on the basis of UK cases that are closer to the French extremist populations, with a legal threshold for what constitutes a terrorist or an assimilated terrorist offence, which is similarly low. Lastly, ERG's structure is simpler and contains less items requiring access to classified data, a crucial factor in a jurisdiction with little interagency information sharing. Although the two tools are intrinsically comparable, ERG seems overall better suited to the French context. This exploratory conclusion ought to be confirmed with field comparisons.

The Release and Community Supervision of Radicalised Offenders: Issues and Challenges that Can Influence Reintegration

“…While specific risk assessment tools for radicalised offenders have been developed, such as the Extremism Risk Guidance 22 + (ERG 22 +) 16 and Violent Extremist Risk Assessment Version 2 Revised (VERA 2R), 17 their predictive value is still unclear, particularly given the lack of validation studies. 18 Other important issues are the applicability of these tools across different jurisdictions and terrorist groups 19 and their consistent application by practitioners, which are essential to their validity. It is unknown whether these tools can help to improve the accuracy of any current assessments of risk and needs that are already being conducted by authorities.…”

Risk assessment and management in violent extremism: a primer for mental health practitioners

“…Specialist guidance on risk assessment and management in relation to violent extremism does exist (for recent overviews of the field, see Hart et al, 2017;Herzog-Evans, 2018;Logan & Lloyd, 2019;Scarcella et al, 2016). For example, in England and Wales, the Extremism Risk Guidance-22+ (ERG-22+, Lloyd & Dean, 2015;Webster et al, 2017) supports the work of forensic psychologists in Her Majesty's Prison and Probation Service (HMPPS) to understand and manage the risk potential of already convicted terrorist offenders.…”

Understanding Lone-Actor Terrorists: The Global Context and How it can be Applied to New Zealand

“…87 While there are still similarities between the two samples, it is also possible that the New Zealand context is somewhat different to those overseas. Although there are various gaps in the below table that could be enhanced by classified information, 88 the New Zealand-specific results could aid better understanding of the domestic lone-actor context. Understanding New Zealand's context can be further enhanced through analysis of Police data relating to a lone-actor cohort.…”
