Brief Psychiatric Rating Scale

The Brief Psychiatric Rating Scale (BPRS) is rating scale which a clinician or researcher may use to measure psychiatric symptoms such as depression, anxiety, hallucinations and unusual behaviour. Each symptom is rated 1-7 and depending on the version between a total of 18-24 symptoms are scored. The scale is the one of the oldest, widely used scales to measure psychotic symptoms and was first published in 1962.
