| Purpose | Delirium Rating Scale-Revised-98 (DRS-R-98) — administration and scoring reference. |
Administration
A trained clinician integrates examination and interval observations using the chosen DRS-R-98 anchors.
Scoring method
Thirteen severity items and three diagnostic items; severity and total scores distinct.
Interpretation & limitations
- Distinguish the severity subtotal from the overall score that also includes the diagnostic items.
- Interpret the findings alongside the clinical interview, functioning, history and relevant physical assessment.
- Do not compare the 13-item severity subtotal directly with a cutoff specified for the full 16-item score.
- Use the original instrument and manual for item wording, rating anchors, missing-data rules and any normative conversions. This reference does not establish a diagnosis or select treatment.
