Brief Psychiatric Rating Scale (BPRS)
Supplemental: Epilepsy, Mitochondrial Disease (Mito), and Parkinson's Disease (PD)
Short Description of Instrument
Purpose: To assess patients who display symptoms of schizophrenia and other psychotic disorders. The Brief Psychiatric Rating Scale (BPRS) is an 18-item scale measuring.
Description: An 18-item scale that measures positive symptoms, general psychopathology and affective symptoms. Each item is scored on 0-7 Likert scale
ranging from "Not Present" to "Extremely Severe". The instrument is administered through a combination of clinician interview and observations from the patient's family from the previous 2-3 days. A pediatric version is also available.
Comment: A well-established scale that is sensitive to changes and allows for broad evaluation. Item score grouping allows scoring on specific symptoms (i.e. mannerisms and posturing). However it is limited in scope as it focuses on positive and general psychopathology.
Primary Dependent Measures: Total score (0-126).
Time Estimates: 20-30 minutes.
