The Brief Psychiatric Rating Scale (BPRS) is one of the oldest and most widely used clinician instruments for measuring overall psychopathology across psychotic and affective illness. This scale covers the core, speech- and content-localizable items that an annotator can ground in a transcript.
Most items are evidence-mode: highlight the passage that supports a rating of somatic concern, anxiety, guilt, grandiosity, depressive mood, hostility, or suspiciousness. Two items concern disordered form or content of thought — Conceptual Disorganization and Unusual Thought Content — and are more instance-like: mark the specific utterances that are disorganized or that voice a delusional idea. Some items overlap neighbours (anxiety vs inner tension, hostility vs suspiciousness) — see each item's Contrastive Learning section. Rate only the subject's presentation.
