The Extremist Risk Intervention Scale (ERIS) is a practical scoring tool useful for those on Behavioral Intervention Teams, law enforcement, and counter-terrorism teams to assess and intervene with extremist and terrorist violence.
The Extremist Risk Intervention Scale (ERIS) is a researched-based expert system useful for assessing individuals during an in-person interview who have expressed a hardened perspective (typically on religious, political or social justice issues) who then feels justified acting violently to others. Those using the SIVRA-35 are recommended to have completed a NaBITA course on the instrument to better understand the creation, administration and interpretation of the measure. The tool should be used in conjunction with further training and study. A starting place for this would be reading this article, this scoring sheet or contacting the author Brian Van Brunt, at the bottom of the page.
Risk Elements (RE): Score 0 (for not present), 1 (for partially present or unknown), or 2 (for present).
Free Falling: Experience of bleakness
Outsider: Experience of discrimination and societal disengagement
Roadblocks: Obstacles to goals
Hardened Warrior: Development of hardened point of view and justification for violence
Dangerous Belonging: Seeking reassuring group affiliation with polarizing, extremist ideologies
Protective Elements (PE): Score 0 (for not present), 1 (for partially present or unknown), or 2 (for present).
Firm Foundation: Experience environmental/ emotional stability.
Safe Spaces: Experience of social health and connections.
Open Roads: Access to non-violent outlets.
Otherness: Development of empathy/inclusivity.
Critical Awareness: Seeking positive social or individual action.
Mobilization Factors (MF): Score either 0 (for not present) or 1 (for present) each, then label low (if 1–2 factors are present), moderate (if 3–5 factors exist), and high (if 6–10 factors are present).
Direct threat
Escalation to action
Catalyst event(s)
Group pressure or rejection
Acquisition of lethal means
Narrowing on target
Fantasy rehearsal and preparation for attack
Note: Dangerousness and violence, from a student , faculty, or staff member is difficult, if not impossible, to accurately predict. This training topic offers research-based techniques and theories to provide a foundational understanding and improved awareness of the potential risk. The training or tool should not be seen as a guarantee or offer any assurance that violence will be prevented.
