Format: A four-feature abbreviated motor-subtyping scale derived by latent-class analysis. It assigns the same broad motor-subtype classes as the parent DMSS;

  • Strengths: Rapid four-feature classification with good concordance to the full DMSS
  • Limitations: Abbreviated subtype classifier, not a delirium detection or severity measure

Evidence

Evidence maturityNo eligible DTA study identified

Reported metric context

Four-item motor-subtype classification; good concordance with the full DMSS (κ=0.63; n=375 with delirium).
