Programs
Crisis prevention
Crisis prevention: early detection of acute mental-health crises, safety-plan support after emergency care, consent-based detection of transitions into isolation and immediate counsellor handoff for students. Specifications and evidence use abstract codes and placeholders only.
This is a research record, not a help service. If you are in Korea and need to talk to someone now, the suicide prevention counselling line 109 can be reached by phone. Elsewhere, contact your local emergency number.
Projects
Suicide Prevention Research for People with Mental Illness
Evaluate event timing and references to supporting evidence in synthetic longitudinal records.
Suicide Prevention Research for Bereaved People and Attempt Survivors
Use synthetic replay to check the flow of a safety plan and transitions to designated responses.
Social Isolation and Suicide Prevention Research
Assess whether changes in everyday routines can serve as indicators of sustained isolation.
Student Suicide Prevention Research
Test whether a designated screen opens promptly following a marked crisis state in synthetic counselling records.
Target, evidence, next check — kept apart
A target is what the project set out to reach. Evidence is what has been measured, in which scope. The next check is what would change the reading.
| Project | Internal target | Evidence so far | Next check |
|---|---|---|---|
| 12-1 · Acute crisis signals | At least 90% recall for acute crisis signals | Synthetic harness (prevent12) · Common synthetic checks | Use structured event markers for synthetic evaluation. Define the requirements for longitudinal labels in external evaluation. |
| 12-2 · Safety-plan transitions | Zero clinically disallowed response events on the fixed test | Synthetic harness (prevent12) · Common synthetic checks | Lock the synthetic transition table and denominator. Define the independent outcomes required for further follow-up. |
| 12-3 · Social isolation | At least 85% precision for detecting transitions into sustained isolation | Synthetic harness (prevent12) · Common synthetic checks | Register the scale, time window and eligibility criteria for isolation. Test missing sensor readings and ordinary interruptions in simulation. |
| 12-4 · Student crisis handoffs | 100% immediate handoff after a detected crisis state | Synthetic harness (prevent12) · Common synthetic checks | Lock decision, success state and maximum delay for synthetic events. Register eligibility criteria for adolescent reference material. |

Boundary cases recorded before evaluation
- 100% traceability of fixed test decisions to source documents and spans
- Leakage from records created after the event
- Sensitivity to missing records and shortcuts based on age or diagnosis labels
- Transition to the predefined pathway after an out-of-scope request
- Withholding or switching a response when records are incomplete or conflicting
- Separate denominators for follow-up scenarios involving bereaved people and attempt survivors
- Distinguish vacations, battery depletion and device non-wear from observed changes
- Check for storage of raw location or text fields
- Reject inferences drawn from unverified linkage of regional and individual data
- Transition tests based on structured synthetic crisis markers
- Abstention with ambiguous markers and missing context
- Check for unrestricted responses after a handoff
What the evidence covers
Recall in actual records requires a predefined population, observation window, timestamped independent reference and an eligible positive denominator.
Transition behaviour and prevention after discharge require different follow-up evidence. The source and access terms for the follow-up cohort remain unverified.
Living alone, short-term stress, subjective loneliness and sustained isolation are separate endpoints. Calculate precision only against verified transition labels.
Detection sensitivity and handoff rate use different denominators. An independent test corpus needs age, language and timestamped crisis annotations.
