The Brief Psychiatric Rating Scale (BPRS) does not focus solely on schizophrenia symptoms. Instead, it is used to measure symptoms such as depression, anxiety, hallucinations and other similar behaviors. It is a 24-item questionnaire on which symptoms are rated on a 1–7 scale. The BPRS schizophrenia scale is slightly older than other questionnaires. However, the BPRS has been shown to be particularly good at capturing affective symptoms related to the manic dimension of schizophrenia.
