Science
Instruments, scoring, flags and what is not yet proven.
This page is deliberately plain. It is built for a sceptical clinician or a diligence analyst: what ORMAI implements, how it is scored, what it flags, and exactly where validation stands.
Built on validated instruments, with psychometric validation under way. ORMAI is decision support and does not diagnose.
Instruments
What is implemented today.
| Instrument | Full name | Role in ORMAI |
|---|---|---|
| AMTS | Abbreviated Mental Test Score | Brief cognitive screening, scored deterministically with banding. |
| PHQ-9 | Patient Health Questionnaire, India-validated | Mood screening. Item 9 triggers an immediate escalation path, never a chatbot response. |
| CARI-Q India | Caregiver Assessment of Relative Independence Questionnaire | Five modules covering function, safety, behaviour, social and family context. Reverse-scored into the Care-Q Index, 0–100. |
| FAMILIA-Q India | Family and caregiver context instrument | Relationship modules for spouse, son, daughter and daughter-in-law, plus spiritual, community and financial subscales. |
| ZBI | Zarit Burden Interview, 12-item | Caregiver and care-staff burden screening. |
RUDAS and MADRS appear on the instrument roadmap; they are not implemented in the shipping product and are not scored today.
Deterministic alert engine
Flags are derived from scores, without AI.
This is the most credible AI-safety property ORMAI has: conversational support is AI, and scoring and alerting are not.
| Severity | Trigger | Action surfaced |
|---|---|---|
| Critical | PHQ-9 item 9 positive (thoughts of self-harm). | Immediate safety review and escalation. |
| High | CARI-Q A-Q8 = 3, family non-recognition. | Immediate specialist referral regardless of other scores. |
| High | CARI-Q A-Q11 = 3, safety judgment lost. | Must not be left unsupervised near gas, stairs or hot surfaces. Home-safety review. |
| High | CARI-Q B-Q6 = 3, kitchen fire risk. | Disable gas supply when staff are absent. |
| High | CARI-Q B-Q10, falls. | Falls-prevention review. |
| High | PHQ-9 ≥ 20. | Geriatric-psychiatry referral. |
| High | AMTS ≤ 3. | Severe cognitive impairment. Full supervision. |
| High | CARI-Q E-Q11, abandonment risk. | Social-work escalation. |
| Medium | Any CARI-Q module ≥ 28/36. | Module flagged “Needs support” with a named domain. |
The product ships free helpline routing for caregivers in distress.
