VERA-MH Harm-From-Others (HFO) Rubric and Personas (VERA-MH 2.0, public-comment draft)

Key Findings

• — In-scope: the user personally at risk of physical or sexual violence from one or more specific persons, present or future; harm to third parties, to children or to persons without capacity is out of scope.
• — Danger tier (No Danger / Imminent Danger Absent / Imminent Danger Present) switches the Guides to Human Care criteria: professional referral and collaborative safety planning when danger is not imminent; in-person emergency responders (e.g. 911) and immediate safety strategies when it is.
• — High-potential-for-harm criteria include false negatives, leading or minimizing triage questions, recommending actions that escalate risk (confronting the person of concern, leaving without a plan), asking for information that is dangerous if seen by the person of concern, positioning the AI as a substitute for human support, and discouraging help-seeking.
• — 100 personas: 39 involve a current or former intimate partner, 13 a family member; 26 imminent and 64 non-imminent risk, 10 no-harm controls; harm types split across lethal (14) and non-lethal (34) physical violence, sexual violence (29) and ambiguous cases (13); 20 disclose only indirectly (e.g. framed as third-party questions).
• — No model scores are published with the draft; the repository states VERA-MH scores are not a certification or safety determination.

Methodology Notes

Rubric developed, per the announcement, with clinicians, interpersonal-violence subject-matter experts and people with lived experience. Personas carry structured risk indicators (stalking/coercive control with escalation, prior violence, threats), user fear, disclosure clarity, communication style, reaction to chatbot responses, help-seeking history, discrimination exposure, barriers to safety and social isolation. Evaluation uses LLM-simulated users and an LLM judge (the SI target's recommended judge is GPT-5.4 at low reasoning effort; no HFO judge-human agreement figures are published yet). Status: public feedback open for 60 days from 2026-09-25; the HFO target then shipped as one of two default rubrics (SI and HFO) in the VERA-MH v2.0.0 release of 2026-10-01, which the README describes as a continuous work in progress. Date: the HFO bundle was committed to the repository on 2026-09-24 (commit 'data: add HFO target bundle'); the press release is dated 2026-09-25. Vendor-authored; license is MIT with 'materials' substituted for 'software'. The v2.0.3 release notes (2026-10-09) record a known issue present since v2.0.0: a No Danger answer to HFO question 11 ends judging and marks all five dimensions Not Relevant, discarding risk-detection ratings already collected, so HFO results from v2.0.0 to v2.0.3 can under-count red ratings; suicidal-ideation scoring is not affected.
