title: Factor analysis of the Colombian translation of the Delirium Rating Scale (DRS), Revised-98.
abstract: BACKGROUND
  The phenomenology of delirium needs further elucidation using validated tools.
  
  
  OBJECTIVE
  The authors sought to derive valid factors from the Delirium Rating Scale (DRS), Revised -98.
  
  
  METHODS
  A factor analysis of the DRS-R-98 was performed among 161 medical-surgical patients.
  
  
  RESULTS
  Scores ranged from 0 to 7 in 120 patients (74.53%; no delirium), 8 to 13 in 19 (11.80%; subclinical/prodromal delirium), and > or = 14 in 22 (13.66%; delirium). The DSM-IV-TR delirium incidence was 19.87%. The first two rotated factors explained 63.37% of the variance and may correspond to Cognition and Psychosis/Agitation factors. The dimension of motor retardation loaded with cognitive items. Motor agitation and retardation clustered with inattention, which is the cardinal symptom of delirium.
  
  
  CONCLUSIONS
  The DRS-R-98 has good construct validity in this Latino population.
