Severity Index for PIE Case Formulation

The Severity Index is a practitioner-only PIE case formulation tool. Practitioners use it to record a standardized severity indication for an already identified problem or condition so severity can be reviewed across issues or over time.

Use this background section to understand when the tool fits, how practitioners use it, and what to consider before sharing it with clients.

Requires a focal issue

A severity indication is meaningful only when attached to a specific identified problem or condition. The tool should prevent final severity entry without that connection.

Comparison boundary

The review may show higher, lower, changed, or missing only when the underlying index structure supports comparison. It must not create direct trend claims across incompatible structures.

Practitioner interpretation

The system displays the severity indication and history; intervention urgency and intensity remain practitioner decisions.

Does the Severity Index decide intervention urgency?

No. It records and displays a severity indication. Decisions about urgency or intensity remain practitioner interpreted.

Can severity be entered without a problem or condition?

No. A severity value must be tied to a focal problem or condition.

Are the severity levels included in this public demo?

No. Exact levels, labels, anchors, and scoring rules are unresolved and must come from the underlying index structure.

Can repeated severity ratings be compared?

Yes, when compatible index structures are used. Historical ratings should remain separate and reviewable.
