A factor analytic study of the Delirium Rating Scale-Revised-98 in untreated patients with delirium.
Existing factor analytic studies of symptoms of delirium are mostly based on small numbers of patients from specialized settings. This study thus sought to examine the factor structure of symptoms of delirium in a reasonably large sample of untreated patients referred to liaison psychiatric services of a multi-specialty hospital in north India, employing the more commonly used Delirium Rating Scale-Revised Version-1998 (DRS-R-98). ⋯ Thus, the current factor analysis not only confirmed the presence of three principal symptom dimensions of delirium (found in several previous studies) but also extended these findings to a broader group of patients usually referred to liaison psychiatric services.
