DPRS^® (Derogatis Psychiatric Rating Scale)

Author: Leonard R. Derogatis, PhD

The Derogatis Psychiatric Rating Scale (DPRS) instrument, formerly known as the Hopkins Psychiatric Rating Scale, is a multidimensional psychiatric rating scale. The DPRS was designed for use with the SCL-90-R^® instrument or BSI^® self-report instruments. It is often used to validate patients' self-reports.

Designed for use by clinicians trained in psychopathology, the DPRS instrument enables the clinician to rate his or her observations of a patient's psychological symptomatic distress on the same nine primary dimensional scales as the SCL-90-R and BSI instruments. With the DPRS instrument, the clinician can also rate the patient on eight additional dimensions that are important to accurate clinical assessment but that are not amenable to patient self-report.

Common Questions and Answers

What is the difference between the DPRS and B-DPRS^® instruments?
Both the DPRS instrument and the B-DPRS instruments measure the nine symptom dimensions assessed by the SCL-90-R and the BSI instruments. The DPRS instrument measures an additional eight dimensions that are not amenable to patient self-report: sleep disturbance, psychomotor retardation, hysterical behavior, abjection-disinterest, conceptual dysfunction, disorientation, excitement, and euphoria. Thus, the B-DPRS instrument has nine scales and a global index, whereas the DPRS instrument has 17 scales and a global index.

What is the difference between the DPRS and the SCL-90 Analogue™ instruments?
The DPRS instrument is a clinician rating scale, whereas the SCL-90 Analogue instrument is an observer rating scale. The DPRS instrument is designed to be used by clinicians who are trained in psychopathology and who are familiar with the syndromes being assessed. The SCL-90 Analogue instrument is designed for use by health professionals without in-depth training or knowledge of psychopathology.

Is the DPRS instrument the same as the Hopkins Psychiatric Rating Scale?
Yes. They are the same clinician rating scale; only the name was changed.
