What is it about?
Using a multisite pooled international delirium database, we applied confirmatory factor analysis to Delirium Rating Scale-Revised-98 (DRS-R98) to verify the hypothesis of two factors for delirium.

Why is it important?
Because DRS-R98 evaluates in a standardized way the clinical characteristics of delirium, confirmatory factor analysis of this scale contributes to the understanding of the phenotype of the disorder.
Perspectives
Confirmatory factor analysis verifies that the delirium is composed of two factors. Core symptoms (cognitive, language, thought process, sleep-wake cycle, motor retardation), except motor agitation, loaded onto Factor 1. Motor agitation loaded onto Factor 2 with noncore symptoms (delusions, affective lability, and perceptual disturbances). Factor 1 loading supports delirium as a single construct, but when accompanied by psychosis, motor agitation’s role may not be solely as a circadian activity indicator.
