What is the BPRS?
The Brief Psychiatric Rating Scale (BPRS) is an 18-item clinician-rated instrument for assessing the severity of psychiatric symptoms. Developed by Overall and Gorham in 1962, it covers a broad range of psychopathology including psychotic symptoms, mood disturbance, anxiety, hostility, and cognitive disorganisation.
The BPRS remains one of the most widely used measures of psychiatric symptom severity, particularly in acute psychiatry, clinical trials, and treatment monitoring for serious mental illness.
How BPRS Scoring Works
Each of the 18 items is rated from 1 (Not present) to 7 (Extremely severe) based on the clinical interview and observation. The total score ranges from 18 to 126.
Overall & Gorham (1962) published the BPRS without defining total-score severity cutoffs. Researchers typically set their own thresholds per study depending on the population and construct under investigation. Clinical interpretation should focus on individual item scores (rated against the published 1-7 severity anchors) and change over time rather than a total-score severity band.
Ratings should be based on both the patient's subjective report and the clinician's objective observation during the interview. Some items (e.g., emotional withdrawal, motor retardation) are rated primarily by observation; others (e.g., anxiety, guilt) rely more on patient report.

Clinical Applications
The BPRS is used in acute psychiatric inpatient settings, community mental health teams, and clinical research. It provides a comprehensive snapshot of symptom severity that is useful for treatment planning, monitoring treatment response, and communicating clinical status between providers.
The expanded 24-item version (BPRS-E) developed at UCLA adds items for bizarre behaviour, suicidality, self-neglect, elevated mood, motor hyperactivity, and distractibility.
BPRS in Australian Practice
The BPRS is used in Australian public mental health services, particularly in acute inpatient settings and early psychosis intervention programs. It complements the mandated HoNOS (Health of the Nation Outcome Scales) by providing more detailed symptom-level information.
As a US federal government funded work (NIMH/VA), the BPRS is in the public domain.
Frequently Asked Questions About the BPRS
Is the BPRS free to use?
Yes. The BPRS is a US federal government funded work (NIMH/VA) and is in the public domain. No permission is required.
How long does the BPRS take to administer?
The BPRS takes approximately 15-20 minutes to complete as part of a standard clinical interview. It can be incorporated into routine psychiatric assessment rather than requiring a separate administration.
Send this assessment to clients →What is the difference between the 18-item and 24-item versions?
The original BPRS has 18 items. The UCLA expanded version (BPRS-E) adds 6 items for more comprehensive assessment. Both versions are in the public domain.
